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

Embodiment Construction

[0014] A composite high flame retardant cable material with excellent insulation properties, made of the following raw materials in parts by weight (kg): high-density polyethylene 89, polyolefin elastomer 9, decabromodiphenyl ether 15, antimony trioxide 7 , metallocene polyethylene 2, nano magnesium hydroxide 2, cyclohexane 4, γ aminopropyl triethoxysilane 0.2, dimethyl silicone oil 2, accelerator TMTD 0.6, ditetradecyl alcohol ester 2, chlorine Chemical paraffin 3, zinc oxide 3, calcium zinc stabilizer 1.

[0015] The composite high flame-retardant cable material with excellent insulation performance is made by the following specific steps:

[0016] (1) Add decabromodiphenyl ether and antimony trioxide into the high-speed mixer, mix at 80°C for 15 minutes, then add half of the amount of high-density polyethylene into the high-speed mixer, and mix at 90°C for 10 minutes Finally, put the mixed material in an open mill, masticate it at 145°C for 8 minutes to produce a tablet, c...

Abstract

The invention discloses a composite flame-retardant cable material with an excellent insulation performance. The cable material is composed of the following components in parts by weight: 89 to 91 parts of high density polyethylene, 9 to 11 parts of polyolefin elastomer, 15 to 17 parts of decabromodiphenyl ether, 7 to 9 parts of antimony (III) trioxide, 2 to 3 parts of metallocene polyethylene, 2 to 3 parts of nano magnesium hydroxide, 4 to 5 parts of cyclohexane, 0.2 to 0.3 part of gamma-amino propyl triethoxysilane, 2 to 3 parts of dimethyl silicone oil, 0.6 to 0.8 part of promoter TMTD, 2 to 3 parts of bis(tetradecyl alcohol ester), 3 to 4 parts of chlorinated paraffin, 3 to 5 parts of zinc oxide, and 1 to 2 parts of calcium-zinc stabilizing agent. The formula is reasonable, high density polyethylene is compounded with polyethylene elastomer, the cable speed and insulation performance of the material are both improved, the fluidity of the produced material is good, and the material can be easily plasticized, does not contain any substance that does not meet the environment-friendly requirements, will not pollute the environment, and at the same time, has the advantages of high efficient low smoke flame retardant property, strong anti-puncture performance, and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a composite high flame-retardant cable material with excellent insulation performance 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 begin...
