Problems solved by technology

At present, PE resin-plastic composite materials on the market generally have the problems of excessive rigidity and insufficient toughness, which are manifested in the bending failure load and low ball impact strength during testing, that is, they are prone to cracking and crushing when they are impacted during actual assembly and use. , which is determined by the physical and chemical properties of the added waste resin powder and other organic resin waste itself
Although the addition of wood flour can improve some of the mechanical properties of PE resin-plastic composites, the interface compatibility between wood flour and PE plastics is too poor, and excessive addition will reduce the mechanical properties
In addition, although the mechanical properties of PE resin-plastic composite materials are higher than those of wood products and plastic products, the overall range is not very large.

Description

technical field [0001] The invention relates to the technical field of processing polymer materials, in particular to a PE-PMMA plastic material and a preparation method thereof. Background technique [0002] Resin-plastic composite material is a new type of polymer composite material with excellent performance in recent years. It is mainly made of organic resin waste, plastic and fiber materials in a certain proportion to form a processing unit, adding an appropriate amount of processing aids and other functional modifications. It is a profile processed by extrusion, injection, pressing and other molding methods. It combines the dual advantages of wood and plastic, not only has the characteristics of acid and alkali resistance, corrosion resistance, low water absorption, and easy cleaning, but also has greatly improved mechanical properties. At present, PE resin-plastic composite materials on the market generally have the problems of excessive rigidity and insufficient tou...
