Problems solved by technology

[0002] Chlorinated polyethylene rubber is a saturated polymer material with excellent heat aging resistance, weather resistance, ozone resistance, oil resistance, flame retardancy, corona resistance and processing performance; chlorinated polyethylene rubber is a non-toxic Self-reinforcing rubber, when used to manufacture wire and cable sheath rubber, the vulcanized rubber will have insufficient tear strength, and the demoulding process will often cause product damage and high scrap rate, so appropriate reinforcement must be used by adjusting the formula agent to improve its performance

Abstract

The invention discloses a preparation method of chlorinated polyethylene rubber, and belongs to the field of a rubber material. The chlorinated polyethylene rubber comprises the components in parts bymass: 100 to 140 parts of chlorinated polyethylene rubber CPE135A, 10 to 30 parts of toughening agent POE1851, 20 to 30 parts of a plasticizer TP95, 2 to 4 parts of a plasticizer TAIC, 100 to 200 parts of talcum powder, 0.5 to 2 parts of a coupling agent KH570, 3 to 10 parts of a vulcanizing agent BIPB, 1 to 2 parts of magnesium oxide, 1 to 5 parts of zinc stearate, 2 to 6 parts of chlorinated paraffin, 1 to 5 parts of paraffin, 4 to 12 parts of inorganic flame retardant Sb2O3, and 30 to 80 parts of a casting waste residue XJ01 reinforcing agent; after the components are mixed, the mixture isvulcanized to obtain the product. The invention provides the chlorinated polyethylene rubber which is excellent in appearance, high and medium in hardness, good in demoulding performance, high tear resistance and high in elongation at break.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a chlorinated polyethylene rubber. Background technique [0002] Chlorinated polyethylene rubber is a saturated polymer material with excellent heat aging resistance, weather resistance, ozone resistance, oil resistance, flame retardancy, corona resistance and processing performance; chlorinated polyethylene rubber is a non-toxic Self-reinforcing rubber, when used to manufacture wire and cable sheath rubber, the vulcanized rubber will have insufficient tear strength, and the demoulding process will often cause product damage and high scrap rate, so it is necessary to use appropriate reinforcement by adjusting the formula agent to improve its performance. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention intends to develop a chlorinated polyethylene rubber with excellent appearance, medium to high hardness, good mold release pe...
