Problems solved by technology

The European Union will fully implement the ROHS directive on July 1, 2006. This decree requires that electrical and electronic products placed in the EU must not contain polybrominated diphenyl ethers and polybrominated biphenyls. This decree has seriously restricted the export of electrical and electronic products in my country.

Embodiment 1-3

[0026] Using PBT / ABS as matrix resin, styrene-acrylonitrile copolymer grafted glycidyl methacrylate as compatibilizer, TPP as flame retardant, adding montmorillonite, 1098 / 168 (1:1) and 1076 For antioxidants.

[0027] Matching ratio 1-3

[0028]

[0029] Put all the components in proportion into a high mixer and mix for 4 minutes, then extrude and granulate with a screw extruder, and the processing temperature is 240°C.

[0030] The sample prepared according to embodiment 1-3 is compared with traditional bromine-antimony flame retardant system:

[0031] The mechanical performance test is based on the ASTM standard, and the flame retardant performance test is based on the UL94 standard.

Abstract

The invention relates to a PBT and ABS flame- proof material. The component and their weight proportion are follows: 30-70% of PBT, 10-50% of ABS, 1-20% of copolymers of styrene and acrylonitrile, 1-20% of styrene-acrylonitrile copolymer graft glycidyl methacrylate, 1-20% of montmorillonite, 1-20% of flame- proof agent, 0.1-1% of anti-oxidant. The PBT / ABS flame- proof material possesses high flame- proof performance, the flame- proof grade reaching V0 class of UL 94 standard, and also improves material performance, especially the rigidity and thermal resistance. The stability of the product size is good. The inventive flame- proof material belongs to the environmental protection product, and is applicable to inject and shape electrical apparatus that requires environmental protection and flame proof.

Description

technical field [0001] The invention relates to a PBT and ABS flame retardant material, in particular to a PBT and ABS nano flame retardant material which can be used for injection molding various electronic and electrical equipment and household electrical appliances which have environmental protection flame retardant requirements and are for export. technical background [0002] Nearly 95% of the flame retardants used in the current flame-retardant PBT / ABS are halogen-containing flame retardants, especially the bromine-containing flame retardants represented by polybrominated diphenyl ethers and polybrominated biphenyls have high efficiency and low dosage. The performance of the material has little impact, and the price is moderate, and its performance / price ratio is unmatched by other flame retardants. Therefore, 70% to 80% of the electrical and electronic products for export in my country use this type of flame retardant. However, in recent years, brominated flame retarda...
