Abstract
In this paper, the areca fiber was extracted by physical and chemical treatment, and then the areca fiber/natural latex composite was prepared by natural latex impregnation technology. In order to combine areca fiber and natural rubber latex better, three silane coupling agents with different action mechanism were selected: Si−69, KH550, and KH570 which were used to treat the areca fiber/natural latex compound. The results show that the silane coupling agent can change the surface of the fiber from hydrophilic surface to organophilic surface, making the bonding of areca fiber to natural latex more closely. At the same time, the mechanical properties, physical and mechanical properties, swelling properties, and dynamic viscoelastic properties of the tightly bonded areca fiber/nature latex composites were improved. After observing the micro-structure through a scanning electron microscope, it was found that the three silane coupling agents could effectively bind areca fiber and natural latex to enhance the performance of the composite material, of which Si−69 performed best, and the tensile strength and tear strength of the composite increased by 21.19% and 12.90% respectively.
Highlights
With the development and research of rubber, it was found that the combination of natural rubber and fiber helps rubber heighten its properties of high modulus, high hardness, cutting resistance, tear resistance, puncture resistance, fatigue resistance, and creep resistance [1,2,3]
This paper mainly studied the effect of silane coupling agent on the modification of areca fiber/natural latex
According to the experimental results, it was found that the –R group in the silane coupling agent was an organic functional group which could react with organic compounds; −Si(OR0 )3 was the silane oxygen group which could react with inorganic substance
Summary
With the development and research of rubber, it was found that the combination of natural rubber and fiber helps rubber heighten its properties of high modulus, high hardness, cutting resistance, tear resistance, puncture resistance, fatigue resistance, and creep resistance [1,2,3]. Natural plant fiber with its green environmental protection, renewable, degradable, pollution-free, and many other advantages has been widely used in medicine, construction, paper, textile, and other fields, and is becoming more and more mature [4]. The green treatment of waste tires and recycling of plant fiber is an urgent problem to be solved. The waste tire powder was combined with ordinary plant fiber and the tire was reinforced by natural plant fiber, which could be used in plate production, which can improve the recycling of waste tire [5]. In order to give full play to the function of fiber, it is necessary to improve the interface adhesion between fiber and rubber through modification
