Problems solved by technology

[0003] Plastic skins are used in panels such as plywood, multi-layer boards, decorative panels, and building templates due to their flexibility and convenience. However, these panels have high requirements for wear resistance. The plastic skins prepared by the prior art have low mechanical strength and poor wear resistance. , causing the plate to crack and wear easily, failing to meet the technical requirements and affecting the service life

Abstract

The invention discloses a plastic dough with high wear resistance, which is composed of the following raw materials in weight percentage: recycled polypropylene 25-35, PVC 15-20, ABS plastic 10-20, filler 8-15, vinyl double Stearamide 5-8, flame retardant 0.5-3, antioxidant 1076 0.5-1, processing aid 0.5-3, styrene-butadiene-styrene block copolymer 2-5, polyimide 5-10, acetyl triethyl citrate 2-3, methyl tin 0.5-1, anti-aging agent 264 0.5-1.5. The invention uses recycled polypropylene as the main raw material to realize the economic recycling of solid waste, and the plastic dough can be recycled and reused repeatedly; through the synergistic effect of various raw materials, not only the compatibility of raw materials and the wear resistance of materials are improved , At the same time significantly improve the mechanical properties of the plastic skin, prolong the service life, thereby reducing production and use costs.

Description

technical field [0001] The invention relates to a plastic dough with high wear resistance, which belongs to the field of materials. Background technique [0002] During the development of nearly a hundred years, plastics and plastic products have brought great contributions and infinite convenience to human production and life, but as time goes by, some plastic products are seriously polluted by plastic waste after their life cycle ends. The environment has become an increasingly serious problem. Ma Zhanfeng, deputy secretary-general of China Plastics Processing Industry Association and secretary-general of the Special Committee on Plastic Recycling, also believes that landfilling is not the best way to deal with waste plastics. He said: "The small weight and large volume of plastics in garbage determine its Its final disposal is not suitable for landfill, but it is a macromolecular material with a high calorific value, and its recycling is in line with the basic national po...
