High-fluidity, scratch-resistant and low-temperature-resistant brominated flame-retardant ABS (acrylonitrile-butadiene-styrene)/TPU (thermoplastic polyurethane) alloy material as well as preparation method and application thereof

Abstract

The invention discloses a high-fluidity, scratch-resistant and low-temperature-resistant brominated flame-retardant ABS (acrylonitrile-butadiene-styrene) / TPU (thermoplastic polyurethane) alloy material. The ABS / TPU alloy material mainly comprises the following components in parts by weight: 45-70 parts of ABS resin, 10-30 parts of thermoplastic polyurethane (TPU), 10-15 parts of a brominated flame retardant and 2-5 parts of an antimony compound. The flame-retardant ABS / TPU alloy material prepared by the invention has the advantages of both ABS and TPU, has good wear resistance, good low temperature resistance, excellent flame-retardant effect and wonderful processability; in a preparation method of the alloy material, blending, extrusion and granulation are conducted at one time by a twin-screw extruder, so the process is simple, convenient to operate and suitable for industrial production; and a final product has application values in the fields of electronic electric appliances, communications and transportation, military and national defense and the like.

Description

technical field [0001] The invention relates to an ABS modified composite material, in particular to a high-fluidity, scratch-resistant, low-temperature-resistant bromine-based flame-retardant ABS / TPU alloy material and its preparation method and application, belonging to the field of polymer materials. Background technique [0002] ABS resin is a terpolymer composed of styrene, butadiene and acrylonitrile. It combines the high fluidity of styrene, the rubber toughness of butadiene and the chemical resistance of acrylonitrile. It has excellent processing performance, Low temperature resistance, electrical insulation, chemical corrosion resistance, high gloss and excellent electroplating performance, as well as good creep resistance, high dimensional stability, small molding shrinkage, etc., are widely used in military industry, automobiles, electronic appliances, etc. The field of application is very wide. However, the oxygen index of ABS resin is only 18, which is a flamma...
