preparation example Construction

[0040] The preparation method of the above-mentioned halogenated flame-retardant TPE material comprises the following steps:

[0041] 1) Mix the non-oil-extended styrene-ethylene-butylene-styrene block copolymer SEBS and mineral oil at a ratio of 1:0.5-2 to obtain oil-extended styrene-ethylene-butylene =Styrene block copolymer styrene-ethylene-butylene-styrene block copolymer SEBS, the mixer speed is 1000 rpm, and the mixing time is 3 minutes;

[0042] 2) Disperse and premix the oil-extended styrene-ethylene-butylene-styrene block copolymer SEBS, chlorinated polyethylene, polypropylene, antioxidant, and lubricant in a high-speed mixer to obtain premix B , the speed of the mixer is 800 rpm, and the mixing time is 3 minutes;

[0043] 3) Disperse and mix decabromodiphenylethane, antimony trioxide, talcum powder, and mixture B through a high-speed mixer to obtain premix C. The speed of the mixer is 100 rpm, and the mixing time is 5 minutes;

[0044] 4) Premix C is melted, kneade...

Abstract

The invention discloses a halogen-containing flame-retardant TPE (thermoplastic elastomer) material. The TPE material consists of the following raw materials in parts by weight: 15 to 30 parts of a styrene-ethylene-butylene-styrene block copolymer (SEBS), 10 to 20 parts of chlorinated polyethylene (CPE) , 10 to 20 parts of homo-polypropylene, 15 to 30 parts of paraffin oil, 10 to 20 parts of decabromodiphenyl ethane, 4 to 8 parts of antimonous oxide, 5 to 10 parts of talcum powder, 0.5 to 1 part of a lubricant and 0.15 to 0.3 part of an antioxidant. The halogen-containing flame-retardant material is good in compatibility, high in tensile strength, high in tearing strength and good in environmental protection performance, and has excellent performance in all aspects.

Description

technical field [0001] The invention relates to a halogen-containing flame-retardant TPE material and a preparation method thereof. Background technique [0002] As an important species of organic flame retardants, halogen flame retardants are the earliest used type of flame retardants. Because of its low price, good stability, less addition, good compatibility with synthetic resin materials, and can maintain the original physical and chemical properties of flame retardant products, it is currently the organic flame retardant with the largest output and usage in the world. [0003] Halogen flame retardants can be divided into chlorine flame retardants and brominated flame retardants. [0004] (1) The price of chlorine-based flame retardants is cheap, but their thermal stability is poor, so they are only suitable for products whose processing temperature is lower than 200°C. [0005] (2) The flame retardant efficiency of brominated flame retardants is high, twice that of ch...
