Problems solved by technology

However, ABS and PBT composite materials are usually used as flame retardant materials. Due to the low heat distortion temperature of ABS itself, existing ABS and PBT composite materials still have poor thermal stability as flame retardant materials; The flame retardant performance of ABS itself is extremely low. It is usually necessary to add flame retardants to the ABS and PBT composite materials to improve the flame retardant performance of the material, and the flame retardants have a certain degree of consumption, especially the antimony-based flame retardants. Make the physical and mechanical properties of ABS and PBT worse, and also reduce the gloss of the surface

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ABS composite flame retardant material and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-butadiene-styrene copolymer) resin is a general-purpose thermoplastic developed in the 1940s and has excellent comprehensive properties. However, ABS has a low heat distortion temperature, especially its resistance to organic solvents. [0003] Polybutylene terephthalate (PBT) is a crystalline polyester with good resistance to organic solvents, chemical resistance, self-lubricating properties and molding processing properties. In recent years, it has been used in electrical and electronic industries. It has a wide range of applications. Blending ABS and PBT can not only significantly increase the impact strength of PBT and reduce its brittle-to-ductile transition temperature, but also keep the alloy good tensile properties, thermal properties and chemi...
