Embodiment 1

[0034] With 100 parts by weight of hydrogenated styrene-butadiene block copolymer resin (SEBS) (Baling Petrochemical, YH-561), 30 parts by weight of simethicone oil (Wacker, AK201), polystyrene (poplar BASF, 476L) 15 parts by weight, 40 parts by weight of composite flame retardant, 10 parts by weight of ethylene acrylate maleic anhydride copolymer (Arkema, LOTADER 4210), 1 part by weight of anti-dripping agent PTFE, 1 part by weight of calcium stearate 3 parts by weight of silicon copper and 1 part by weight of each of antioxidant 1010 and antioxidant 168 were fully mixed for 10 minutes at high speed in a high-speed mixer (Zhangjiagang Yili Machinery SHR-500A). Among them, in the composite flame retardant, the weight ratio of phosphoric acid ester, polyphosphate amine and whiteness coated red phosphorus is 1:0.1:2, the phosphoric acid ester is bisphenol A bis(diphenyl phosphate), polyphosphoric acid The degree of polymerization of the amine is 1500, and the whiteness red phosp...

Embodiment 2

[0041] The flame retardant resin composition of the present invention was prepared according to the method described in Example 1, except that a nitrogen-phosphorus composite flame retardant (Hangzhou Jieersi, PNP1) was used to replace the composite flame retardant.

Embodiment 3

[0043] 100 parts by weight of SEBS resin, 40 parts by weight of phenyl silicone oil (Shenzhen Jipeng silicon fluoride material, 255-A / 500CS), 20 parts by weight of polypropylene, 25 parts by weight of composite flame retardant, ethylene methyl acrylate copolymer ( EMA) 15 parts by weight, 5 parts by weight of anti-dripping agent PTFE, 0.3 parts by weight of calcium stearate, 0.3 parts by weight of silicon copper and each 0.2 parts by weight of antioxidant 1010 and antioxidant 168 are fully fully Mix for 10 minutes. Among them, in the composite flame retardant, the weight ratio of phosphoric acid ester, polyphosphate amine and whitening coated red phosphorus is 1:2:5, the phosphoric acid ester is resorcinol (diphenyl phosphate), polyphosphoric acid The degree of polymerization of the amine is 1800, and the red phosphorus coated with whiteness is Lianyungang trust silicified FRW30.

Abstract

The invention provides a flame-retardant resin composition. The composition comprises hydrogenated styrene-butadiene block copolymers, polypropylene and / or polystyrene, a flame retardant and a compatilizer, wherein the composition also comprises silicone oil. The flame-retardant resin composition has good mechanical property and high stretching strength of 100 percent.

Description

technical field [0001] The invention relates to a flame retardant resin composition. Background technique [0002] At present, commonly used wire and cable covering materials and plugs of electrical appliances and chargers are polyvinyl chloride (PVC) and ethylene-vinyl acetate copolymer (EVA) materials. Due to the increasing requirements for environmental protection, the materials for making wire and cable coverings and plugs for electrical appliances and chargers are required to meet ROHS ("Restriction of Hazardous Substances" (Restriction of Hazardous Substances)) environmental protection detection, and must not contain halogens. The PVC material contains a large number of halogen atoms, which will release toxic gases when burned, which will damage the environment and poison human health. In addition, the EVA material has poor heat resistance temperature and oil resistance and corrosion resistance. [0003] Therefore, it is necessary to seek wire and cable covering mat...
