Embodiment 1

[0021] A method for preparing a wide temperature range chlorinated polyethylene cable material, comprising the following steps: in a closed rubber mixer, the high-performance chlorinated polyethylene sample 1 prepared by the patent 201410135748.2 technology: magnesium oxide: zinc stearate: The mass ratio of N,N'-m-phenylene bismaleimide: dicumyl peroxide: antioxidant 1076: carbon black N660: dioctyl phthalate (DOP) is 100:5:2 :0.5:1:1:20:5 are added sequentially. The temperature of the rubber mixing machine is 60°C, and the speed is 20 rpm. After the rubber mixing machine is finished, open the top bolt and discharge the glue. The compounded rubber is extruded and granulated through a single-screw extruder, and dried to a constant weight to obtain a wide temperature range chlorinated polyethylene cable compound.

Embodiment 2

[0025] A method for preparing a wide temperature range chlorinated polyethylene cable material, comprising the following steps: in a closed rubber mixer, the high-performance chlorinated polyethylene sample 2 prepared by the patent 201410135748.2 technology: magnesium hydroxide: zinc oxide: three Allyl isocyanurate: 2,5-Dimethyl-2,5-bis(tert-butylperoxy)hexane: Antioxidant RD: Carbon black N550: Dioctyl sebacate (DOS) The mass ratio of 100:20:5:3:3:5:60:30 was added in sequence. The temperature of the rubber mixing machine is 80°C, and the speed is 100 rpm. After the rubber mixing machine is finished, open the top bolt and discharge the glue. The compounded rubber is extruded and granulated through a single-screw extruder, and dried to a constant weight to obtain a wide temperature range chlorinated polyethylene cable material.

Embodiment 3

[0029] A method for preparing a wide temperature range chlorinated polyethylene cable material, comprising the following steps: in a closed rubber mixer, the high-performance chlorinated polyethylene sample 3 prepared by the patent 201410135748.2 technology: magnesium oxide: zinc oxide: triene Propyl isocyanurate: 2,5-Dimethyl-2,5-bis(tert-butylperoxy)hexane: Antioxidant RD: White carbon black Si-175: Dioctyl sebacate ( DOS) were added sequentially at a mass ratio of 100:10:3:1:1:2:40:15. The temperature of the rubber mixing machine is 70°C, and the speed is 60 rpm. After the rubber mixing machine is finished, open the top bolt and discharge the rubber. The compounded rubber is extruded and granulated through a single-screw extruder, and dried to a constant weight to obtain a wide temperature range chlorinated polyethylene cable material.

Abstract

The invention provides a preparation method for a wide-temperature-range chlorinated polyethylene cable material. Acid acceptors, activating agents, vulcanizing accelerators, vulcanizing agents, antioxidants, filler and plasticizers are added into chlorinated polyethylene prepared according to the patent 201410135748.2, so that the temperature resistance grade of the material is improved, and the defects of poor weather resistance, ozone resistance and heat resistance of the material are overcome. Meanwhile, the original physical and mechanical properties of the material are improved by 20-40%, the temperature resistance grade is improved by 30 DEG C, and the aging resistance is improved by 20-30%.

Description

technical field [0001] The invention relates to a preparation method of a wide temperature range chlorinated polyethylene cable material, which belongs to the technical field of material formula modification, and specifically relates to a process method for preparing a wide temperature range cable material using a wide temperature range chlorinated polyethylene as the main material . Background technique [0002] Today, the temperature range and utilization of polyolefin materials for cables are undergoing major changes. The temperature application range of traditional cross-linked polyolefin materials can no longer meet the needs of the market, and it is also difficult to be compatible with complex electrical components and electrical equipment. At present, the main insulating material for the production of wire and cable is cross-linked polyethylene material. The cross-linking methods of cross-linked polyethylene mainly include chemical cross-linking, silane cross-linkin...
