Anti-cracking waterproof high-performance asphalt cable material and preparing method thereof

Abstract

The invention discloses an anti-cracking waterproof high-performance asphalt cable material. The cable material is prepared from, by weight, 94-96 parts of high-density polyethylene, 15-17 parts of decabromodiphenyl ether, 7-9 parts of antimonous oxide, 2-3 parts of metallocene polyethylene, 2-3 parts of nano-magnesium hydroxide, 4-5 parts of cyclohexane, 0.2-0.3 part of gamma-aminopropyl triethoxy silane, 4-6 parts of silicon carbide, 3-4 parts of zinc oxide, 2-3 parts of graphene, 9-11 parts of asphalt, 1-1.3 parts of accelerant DM, 2-3 parts of epoxy linseed oil, 10-12 parts of ethylene-vinyl acetate copolymer and 10-13 parts of absolute ethyl alcohol. By means of a series of modification, viscosity is reduced, fluidity is improved, compatibility with a base material is improved, flame retardant master batch and anti-breakdown modified master batch are added, and therefore the cable material is higher in high-temperature stability and low-temperature crack resistance, flexible, waterproof, resistant to abrasion, economical and durable and absorbs shock.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an asphalt anti-crack and waterproof high-performance cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with a wide range of uses. According to the amount of plasticizer added, it can be made into rigid, semi-rigid and soft products, and can also be modified by blending with other polymers. , made into a wide variety of products with different properties, the amount is very large, it is one of the world's top five general-purpose plastics. The global demand for PVC resin ranks the top three along with polyethylene and polypropylene, while its consumption in China has risen to the first place. Polyvinyl chloride itself is also an intrinsically flame-retardant material, with a high oxygen index and a good flame-retardant effect, but pure PVC is a rigid segment, which begins to decompose ab...

Problems solved by technology

Among them, blending technology is the most widely used method to improve the dielectric properties of polyethylene, but the blending of different components will form a microscopic interface of two-phase structure, and even the phenomenon of penetration and separation to the surface of the material will affect other aspects of the blend. Dielectric properties, as blending may result in reduced dielectric strength
