ABS flame retardant alloy

Abstract

The invention discloses an ABS flame retardant alloy, which comprises the following materials by weight: 1-2 parts of PE ester, 2-8 parts of zinc borate, 1-9 parts of an acetylacetonate salt, 10-30 parts of PBT, 30-40 parts of ABS, 20-30 parts of styrene, 10-18 parts of montmorillonite, 1-9 parts of an antioxidant, 1-7 parts of a flame retardant APP (ammonium polyphosphate), 1-8 parts of a flame retardant PER (pentaerythritol), 3-9 parts of trichloroethyl phosphate, and 2-9 parts of a halogen-free intumescent flame retardant. By utilizing the synergistic effect of the montmorillonite and the halogen-free flame retardant, the ABS flame retardant alloy disclosed in the invention abandons the traditional flame retardant system, has excellent flame retardant performance and mechanical properties, is harmless to the environment and human health, thus belonging to an environmental protection product. Moreover, the use of montmorillonite reduces the flame retardant dosage, so that the mechanical properties and heat resistance of flame retardant materials are improved to a large extent. More importantly, the production cost is greatly reduced.

Description

technical field [0001] The invention relates to an ABS flame-retardant alloy. Background technique [0002] Nearly 95% of the flame retardants used in the current flame-retardant PBT / ABS are halogen-containing flame retardants, which have little effect on the performance of the material, and the price is moderate, and its performance / price ratio is unmatched by other flame retardants. 70%~80% of the exported electronic and electrical products use this kind of flame retardant. However, in recent years, halogenated flame retardants have been troubled by the problem of dioxins. At the same time, the use of flame-retardant polymer materials will generate a large amount of smoke and corrosive gases during pyrolysis and combustion. At present, the European Union and Japan have successively issued laws and regulations to prohibit the use Such flame retardants. The European Union has fully implemented the ROHS directive since July 1, 2006. This decree requires that electrical and ...
