Embodiment 1

[0014] A preparation method for tough and wear-resistant rubber and plastic products, the method comprising the following steps:

[0015] Step 1. Clean the PVC waste to remove surface impurities, then dry the PVC waste in the sun and air-dry, then send the PVC waste to the crusher for crushing, then pass through the sorting machine to collect the powder, and then put it into the centrifuge to separate the water , and then dried by hot air to reduce the water content to below 1% to obtain PVC waste powder;

[0016] Step 2. Weigh the following raw materials in parts by weight: 200 parts of PVC waste powder, 100 parts of polyvinyl chloride, 20 parts of polycaprolactone, 10 parts of methyl acrylate, 2 parts of triallyl isocyanate, and 2 parts of bayberry wax , 4 parts of ethylene-vinyl alcohol copolymer, 6 parts of phthalic dimethyl anhydride, 1 part of tribasic lead sulfate, 4 parts of sodium polymethacrylate, 3 parts of bis-tert-butylperoxycumene, chlorine 20 parts of sulfonate...

Abstract

The invention discloses a preparation method of a tough wear-resistant rubber and plastic product, which comprises the following steps: proportionally adding the raw materials into a mixer, and uniformly stirring to obtain a mixture; adding the mixture into a reaction kettle, mixing and reacting, extruding and granulating by using a double-screw extruder to obtain modified granules, and grinding the modified granules into powder; mixing polyurethane, the powder, a foaming agent and an emulsifying agent, putting the mixture into a stirrer, uniformly stirring, heating, foaming, and curing for 3-12h to obtain the tough wear-resistant rubber and plastic product. According to the method, the recycled waste PVC plastic is crushed and modified to serve as a production raw material, harmless and resource utilization of the waste plastic is achieved, shortage of plastic resources is relieved, and the method is environmentally friendly, free of pollution and nuisance, capable of being recycled and beneficial to the society. Meanwhile, the prepared rubber and plastic product is good in flame retardance, impact resistance and wear resistance.

Description

technical field [0001] The invention relates to a preparation method of strong and wear-resistant rubber and plastic products. Background technique [0002] The rubber industry is an important part of my country's chemical industry. The basic raw materials of the rubber industry are natural rubber and synthetic rubber. In order to manufacture rubber products that meet the actual performance requirements and improve the processing performance, various chemical processing aids must be added. At present, the general production of rubber and plastic products uses nitrile rubber and polyvinyl chloride resin as the main material, and other auxiliary materials are added for high-temperature blending, and then vulcanizing agent and foaming agent are added to undergo vulcanization and foaming, and finally the preparation of rubber and plastic products is realized. Rubber and plastic materials have excellent properties such as softness, bending resistance, cold resistance, heat resi...
