Problems solved by technology

However, as a degradable composite material, most of its components are still plastic, and the filled plant fibers are all modified. Only the fiber part of the waste composite material can be naturally degraded. Due to the influence of coupling agents, The fiber part is also difficult to completely degrade
"Plastic Industry" published a paper on the development of a degradable plant fiber reinforced starch plastic foam tableware in the 5th issue of 2002, page 45, but the mechanical strength of the material is very low, and it is difficult to be used in other fields except for tableware

Description

technical field [0001] The invention relates to an impact-resistant polystyrene composite material and a preparation process thereof, in particular to a modified impact-resistant polystyrene composite material and a preparation process thereof. Background technique [0002] In today's shortage of petroleum resources, wood-plastic composite materials have excellent physical and mechanical properties and special molding methods (extrusion, injection molding, etc.), which make them widely used. On the one hand, it makes full use of waste plant fiber materials. The cost of raw materials is reduced in terms of production. On the other hand, the filling of plant fibers improves the physical and mechanical properties of composite materials, enabling them to replace wood and plastic products in many fields and change the current situation of serious shortage of oil and forest resources. However, as a degradable composite material, most of its components are still plastic, and the fi...
