Effect of cryogenic treatment on microstructure and properties of acrylonitrile–butadiene–styrene

In order to improve the mechanical behavior of polymer materials for three-dimensional printing. acrylonitrile–butadiene–styrene (ABS) samples are divided into five groups, based on different degrees of cryogenic treatment. A hydraulic universal testing machine is used to test the samples’ tensile properties, percent elongation and bending strength, while each sample’s wear performance is tested by using a tribometer. In addition, the functional groups and the internal molecular chain in every sample are characterized by Fourier transform infrared spectroscopy. The experimental results show that cryogenic treatment is an effective technique for the enhancement of the mechanical properties of ABS, such as its tensile strength, bending strength, wear performance and crystallinity. Particularly, the mechanical properties of ABS are improved after cryogenic treatment at −130°C for 4 h. The tensile strength is improved by 6·31 MPa, 93% higher than that of unprocessed samples. The bending strength is improved by 2·46 MPa, and the wear performance significantly exceeds that of the other groups.

In this research, the effect of adding a virgin Styrene Butadiene rubber (SBR) on the morphology and properties of Acrylonitrile Butadiene Styrene (ABS) waste plastic has been investigated. The blends were prepared by melting method and characterized by means of mechanical testing, Scanning Electron Microscopy (SEM), Thermogravimatric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The obtained results indicated that virgin SBR phase dispersed efficiently, effectively in the ABS matrix and impact strength along with thermal resistance of the blends significantly improved. Thus, investigated results in this work will open promising approach for recycling ABS waste plastic.

A Study on the Influence of Process Parameters on the Viscoelastic Properties of ABS Components Manufactured by FDM Process

Fused Deposition Modelling (FDM) is a fast growing Rapid Prototyping (RP) technology due to its ability to build parts having complex geometrical shape in reasonable time period. The quality of built parts depends on many process variables. In this study, the influence of three FDM process parameters namely, slice height, raster angle and raster width on viscoelastic properties of Acrylonitrile Butadiene Styrene (ABS) RP-specimen is studied. Statistically designed experiments have been conducted for finding the optimum process parameter setting for enhancing the storage modulus. Dynamic Mechanical Analysis has been used to understand the viscoelastic properties at various parameter settings. At the optimal parameter setting the storage modulus and loss modulus of the ABS-RP specimen was 1008 and 259.9 MPa respectively. The relative percentage contribution of slice height and raster width on the viscoelastic properties of the FDM-RP components was found to be 55 and 31 % respectively.

Plating on acrylonitrile–butadiene–styrene (ABS) plastic: a review

ABS is an engineering plastic that has butadiene part uniformly distributed over the acrylonitrile-styrene matrix. It possesses excellent toughness, good dimensional stability, easy processing ability, chemical resistance, and cheapness. However, it suffers from inherent shortcomings in terms of mechanical strength and vulnerability to environmental conditions. Furthermore, it is non-conducting and easily fretted. Plating on ABS can serve to enhance the strength and structural integrity as well as to improve durability and thermal resistance resulting in metallic properties on the ABS material. ABS is described as the most suitable candidate for plating because it is possible to deposit an adherent metal coating on it by only the use of chemical pretreatment process and without the use of any mechanical abrasion. This article aims to review the history of ABS plastics, properties of ABS, processes and mechanisms of plating, and studies of plating on ABS involving mainly eco-friendly methods of plating by discussing the literature published in recent years. The details of electroplating of ABS carried out in the authors’ laboratory are also presented.

Effect of friction and wear parameters on acrylonitrile butadiene styrene/aluminum-boron carbide-glass spheres polymer composites

In the present work, the friction and wear properties of acrylonitrile butadiene styrene based composites filled with aluminum, boron carbide and glass spheres particles were studied. Fillers contents in the ABS were 5, 10, 15, and 20 wt%. The result showed that the addition of fillers to the composite changed the friction coefficient and wear rate. All specimen wear loss increases with increasing load and sliding distance; meanwhile the friction (static and dynamic) coefficient increases. DOI: http://dx.doi.org/10.5755/j01.mech.20.4.7883

Influence of natural clinoptilolite nanoparticles on thermal stability, scratch resistance and adherence properties of Acrylonitrile butadiene styrene (ABS)

In order to improve thermal stability of Acrylonitrile-butadiene-styrene (ABS) polymer, ABS/natural clinoptilolite (Clino) nanocomposite was produced using solvent/non-solvent method. The influence of natural clinoptilolite nanoparticles on scratch resistance and adherence properties of ABS coating on steel coupons was investigated. In order to study the scratch resistance and adherence properties, thin (20 µm) coatings of ABS and ABS/Clino nanocomposites, were prepared by solution casting method. The formation of ABS/Clino nanocomposite was characterized using FTIR spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). Results showed that there is a strong interaction such as hydrogen bonding between ABS and clinoptilolite nanoparticles. The thermal stability of the nanocomposite was examined using thermogravimetric analysis (TGA). TGA results showed an increase in the thermal degradation temperature of the nanocomposite. TGA results indicated that the thermal stability of ABS increases by increasing the Clino content of nanocomposite up to 5 % w/w. Scratch resistance and adherence properties of ABS/Clino nanocomposite coatings were also evaluated. Results showed that the scratch resistance and adherence strength of ABS/Clino nanocomposite coatings are higher than that of pure ABS coatings.

Dielectric, Thermal, and Mechanical Properties of Acrylonitrile Butadiene Styrene Reinforced with Used Tires

AbstractMass production of tires as well as their storage or elimination is a real environmental problem. Various methods for recycling of tires are currently used, such as mechanical grinding, which separates vulcanized rubber, steel, and fibers from tires. Rubber is, then, used in several industrial applications such as flooring, insulations, and footwear. This paper focuses on a new application for old used tires (ground tire rubber, GTR). Tire dust and acrylonitrile butadiene styrene (ABS) have been mixed, and the maximum accepted concentration of GTR can be attained while keeping dielectric, thermal, and mechanical properties within acceptable limits, and therefore their possible industrial application will be in manufacturing of, for example, dielectrics for capacitors, low‐voltage electric fences or electrical cable pipes, and trays. Actually, tire dust with particle sizes <700 µm has been classified into three different groups depending on the particle sizes (p < 200, 200< p < 500, and p > 500 µm). Afterward, ABS has been mixed with different concentrations of GTR, i.e., 5%, 10%, 20%, 50% and 70%, to establish its properties through thermal, mechanical, and dielectric tests. Finally, the fracture surfaces of the composite samples have been evaluated by using scanning electron microscopy. © 2012 Wiley Periodicals, Inc.

Effect of particle size of fly ash cenospheres on the properties of acrylonitrile butadiene styrene-filled composites

Fly ash cenospheres are inexpensive, readily available from coal burning or heavy oil combustion, not an eco-friendly material. If ways can be found to use this, it will serve the twin purposes of facilitating applications for the ash bearing materials and at the same time reduce pollution. One way to achieve this task is to make ash-bearing composites having polymer matrices. The performance of filled polymers is generally determined on the basis of the interface attraction of filler and polymers. Fillers of widely varying particle size and surface characteristics are responsive to the interfacial interactions with the polymers. The present study deals with the effect of particle size (150 mesh, 100 mesh, and 300 mesh) variations in fly ash cenospheres, as a filler with different concentrations (0–40 wt%), on various properties of acrylonitrile butadiene styrene. The mechanical, thermal, and electrical properties of the composite material were evaluated, and the microstructure was investigated through scanning electron microscopy. The smaller particle size showed better properties in comparison with larger particle size. As increasing filler loading, the saturation level is influenced by the agglomeration of filler particles in the polymer matrix. Thus, the performance of polymer filled with fly ash cenosphere composites is the function of the particle size, the dispersion, and the interfacial interaction between the filler particles and the polymer matrix.

Effect of Compatibilizers on the Morphological Properties of ABS and LCP Blends

The blends of acrylonitrile butadiene styrene (ABS) polymer and liquid crystalline polymer (LCP) were prepared using a melt-blending technique in presence and absence of different types of nanosilica. The effect ofZn++coated nanosilica on thermal, dynamic mechanical, and morphological properties of ABS/LCP blends was studied. TheZn++coated nanosilica showed a significant effect on the above-mentioned properties of ABS/LCP blends by reacting at the interface between ABS and LCP. A substantial improvement in storage modulus of ABS/LCP blends was observed in presence ofZn++coated nanosilica. Epoxy encapsulated nanosilica was also used as a compatibilizer in this blend system. It is known that the epoxy end group reacts with the LCP reacting groups. But in this case, we cannot find desirable results, may be due to the presence of ABS as the matrix. So Zn-ion-coated nanosilica proved to be better than that epoxy encapsulated nanosilica for the ABS/LCP containing blends. The SEM morphology also corroborates the above-mentioned argument.

Influence of rubber content in ABS in wide range on the mechanical properties and morphology of PC/ABS blends with different composition

A series of acrylonitrile-butadiene-styrene (ABS) with different rubber content were prepared by diluting ABS grafting copolymer containing 60% rubber with a styrene-acrylonitrile copolymer. ABS prepared were blended with bisphenol-A-polycarbonate (PC) at the ratio of 70/30, 50/50, and 30/70 to prepare PC/ABS blends. Influence of rubber content in ABS on the properties of ABS and PC/ABS blends were investigated. PC/ABS blends with different compositions got good toughness when the rubber in ABS increased to the level that ABS itself got good toughness. The tensile properties and processability of PC/ABS blends decreased with the increase of the total rubber content introduced into the blends. ABS with the rubber content of 30 wt% is most suitable to be used to prepare PC/ABS blends. The rubber content in ABS affected the viscosity of ABS, and subsequently the viscosity ratio of PC to ABS. As a result, the morphology of PC/ABS blends varied. The increase of rubber content in ABS results in finer structure of PC/ABS blends.
