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 high-wear resistance plastic veneer. The plastic veneer comprises the following raw materials in percentage by weight: 25-35% of recycled polypropylene ethylene, 15-20% of PVC (polyvinyl chloride), 10-20% of ABS (acrylonitrile butadiene styrene) plastic, 8-15% of a filler, 5-8% of vinyl bisstearamide, 0.5-3% of a fire retardant, 0.5-1% of an antioxygen 1076, 0.5-3% of a processing aid, 2-5% of styrene-butadiene-styrene block copolymer, 5-10% of polyimide, 2-3% of acetyl triethyl citrate, 0.5-1% of methyltin mercaptide and 0.5-1.5% of an anti-aging agent 264. The plastic veneer takes the recycled polypropylene ethylene as a main raw material, so that economical recycle of solid waste is achieved; the plastic veneer can be repeatedly recycled for use; through synergistic effect of multiple raw materials, not only are compatibility of the raw materials and wear resistance of the plastic veneer enhanced, but also mechanical properties of the plastic veneer are significantly improved, the service life of the plastic veneer is prolonged, and thus the production cost and the using cost are reduced.

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 p...
