Problems solved by technology

Polyethylene is a large variety of thermoplastics. It has the characteristics of light weight, non-toxicity, and excellent chemical corrosion resistance. However, polyethylene has a very low oxygen index and is a flammable material. Polyethylene will produce serious melting when it is burned. Dripping behavior, which brings great difficulties to flame retardancy. In addition to being flammable, polyethylene has high volume resistivity and surface resistivity, which makes it very difficult to charge static electricity during processing and use. Difficult to eliminate, the above two shortcomings have brought great safety hazards to the use of polyethylene and reduced the scope of use

Abstract

The invention discloses an aging-resistant and high-hardness cable material and a preparation method thereof. The cable material is prepared from materials in parts by mass as follows: 20-35 parts of a modified polyurethane composite, 15-30 parts of styrene butadiene rubber, 5-8 parts of polystyrene resin, 3-10 parts of pentaerythritol tetrakis(2-mercaptoacetate), 0.5-1.5 parts of ammonium dichromate, 1-3 parts of dibenzothiazyl disulfide, 20-30 parts of nano-silica, 45-50 parts of activated calcium carbonate, paraffin and the like. The cable material has very high weather resistance, the effect of the environment on a cable sheath is reduced, and besides, the cable material is high in strength, good in hardness, high in shock resistance, excellent in stability, long in service life, good in thermo-oxidation stability, aging-resistance and excellent in mechanical property.

Description

technical field [0001] The invention belongs to the technical field of cable production, and in particular relates to an aging-resistant high-hardness cable material and a preparation method thereof. Background technique [0002] Communication and electric power are the key points of national construction. No matter where the development is, the construction of communication and electric power always takes the lead, so the development of communication and electric power is very fast. The development of communication and electric power industry requires the cooperation of various aspects, among which the cable material is one aspect. The general-purpose wire and cable covering materials are mainly plastic and rubber, and the thermoplastic materials for wire and cable only need to have polyvinyl chloride, polyethylene, and polypropylene. , fluoroplastics, chlorinated polyethers and polyamides, among which polyethylene and polyvinyl chloride are widely used. In my country, the...
