Ways to improve physico-mechanical properties of polymer composites on the basis of secondary polypropylene and natural extenders

Abstract

Creation of composition polymeric materials is one of the most perspective directions of the modern polymeric materials science. When developing such systems there can be problems of compatibility of components, for example between polymer and an excipient. Binding agents enter into composite structure for the purpose of ensuring connectivity of elements. The influences of part-time workers on rheological and physicomechanical behavior of polymeric composition on the basis of the secondary polymeric raw materials filled with natural components of a phytogenesis is studied in this work. It is shown that introduction of the part-time worker to composition affects MFR values - the more the part-time worker is in composition, the more MFR value, and so, and workability is easier. At the same time it should be noted that in case of use as part-time workers of EN13F1F3HH and SanUMBUGO F1 of regularity of change of the MFR a bit differents - increase of MFR values is observed only when content of the part-time worker in composition up to 1% of masses. Studying of rheological data demonstrates that introduction even of a small amount of the part-time worker leads to the fact that resilient properties at the composition containing the modifier are expressed less, the probability of formation of marriage at manufacture of products from these compositions respectively is less. Introduction of modifiers affects also physicomechanical properties of composition. Operation of SunUNBUGO F1 and EN13F1F3HM modifiers is close to each other, and MPP5X – differs. The lowest values of an elastic modulus take place when using as the SunUNBUGO F1 modifier. At the same time, increase filler content in composition reduces already not high values of an elastic modulus. Thus, during the research the basic possibility of regulation of rheological and physicomechanical behavior of polymeric composites not only by introduction of the part-time worker to composition playing a role superficially of the active material but also by regulation of conditions of receiving composites is shown.
