Wear-resistant non-toxic modified plastic production method

[0021] A production process of wear-resistant and non-toxic modified plastics, the specific steps of the production process of wear-resistant and non-toxic modified plastics are as follows:

[0022] S1. Ingredients: Weigh 40 parts of polypropylene, 30 parts of polyvinyl chloride, 25 parts of glass fiber, 15 parts of carbon fiber, 1 part of coupling agent, 10 parts of polytetrafluoroethylene, 0.5 parts of lubricant and 5 parts of low-density polyethylene ;

[0023] S2, material mixing: add the material weighed by S1 into the mixer to fully mix and grind, put it into the vacuum mixer after mixing and grind for 5 minutes, so that the mixture in S1 is fully mixed;

[0024] S3. Extrusion: put the fully mixed material in S2 into a twin-screw extruder to extrude. The temperature of the twin-screw extruder is kept at 180°C, and the speed of the screw is 280r / min. After extrusion, the injection molding temperature 160°C;

[0025] S4. Cooling: Place the injection-molded plastic in S3 i

[0047] A production process of wear-resistant and non-toxic modified plastics, the specific steps of the production process of wear-resistant and non-toxic modified plastics are as follows:

[0048] S1. Ingredients: Weigh 45 parts of polypropylene, 35 parts of polyvinyl chloride, 30 parts of glass fiber, 20 parts of carbon fiber, 1.5 parts of coupling agent, 15 parts of polytetrafluoroethylene, 1 part of lubricant and 7 parts of low-density polyethylene ;

[0049] S2, material mixing: add the material weighed by S1 into the mixer to fully mix and grind, put it into the vacuum mixer after mixing and grind for 5 minutes, so that the mixture in S1 is fully mixed;

[0050] S3. Extrusion: Put the fully mixed material in S2 into a twin-screw extruder to extrude. The temperature of the twin-screw extruder is kept at 220°C, and the speed of the screw is 280r / min. After extrusion, the injection molding temperature 180°C;

[0051] S4. Cooling: Place the injection-molded plastic in S3 i
