Problems solved by technology

Based on the modified plastic particle production equipment combined by the above devices, the modified plastic particle production equipment has the following disadvantages: Considering that the modified plastic wire enters the particle cutting machine only after being cooled by water, the cut plastic particles have water on the surface, Dust will be stuck in the subsequent screening and bagging process, which will affect the quality of modified plastic particles
In addition, the existing plastics have poor wear resistance and are not environmentally friendly.

Abstract

The invention discloses a wear-resistant non-toxic modified plastic production method. The method comprises S1, preparation: weighing 40 to 45 parts of polypropylene, 30 to 35 parts of polyvinyl chloride, 25 to 30 parts of glass fibers, 15 to 20 parts of carbon fibers, 1 to 1.5 parts of a coupling agent, 10 to 15 parts of Teflon, 0.5 to 1 part of a lubricant and 5 to 7 parts of low density polyethylene, S2, blending: adding the weighed materials into a mixer and carrying out full mixing and grinding, S3, extrusion: putting the fully mixed materials into a twin-screw extruder and carrying out extrusion, S4, cooling: putting the molded plastic into a cooling room and carrying out cooling, S5, dry air drying: carrying out dry air drying and cooling on the product obtained by the step S4 through a dry air machine, S6, grain-sized dicing: putting the product obtained by the step S5 into a pelletizer and carrying out grain-sized dicing, and S7, vulcanization: carrying out vulcanization on the particles in a press vulcanizer. Through filling modification of polypropylene and polyvinyl chloride, the wear resistance of the modified plastic is greatly improved, good thermal performances areobtained, environmental friendliness is obtained and toxicity is avoided.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and more specifically relates to a production process of wear-resistant and non-toxic modified plastics. Background technique [0002] Modified plastic particle production equipment is a combination of a series of devices that mix plastic powder raw materials and plastic additives into an extruder, extrude modified plastic wire, and then pass through a particle cutter to complete cutting. [0003] The existing production equipment for modified plastic particles includes a feeding device, an extruder, a cooling device and a particle cutting machine. The cooling device has a very simple structure and is a water tank with cooling water. Based on the modified plastic particle production equipment combined by the above-mentioned devices, the modified plastic particle production equipment has the following disadvantages: Considering that the modified plastic wire enters the particle cutting m...
