High-performance flame-retardant ABS composite material and preparation method thereof

Abstract

The invention discloses a high-performance flame-retardant ABS composite material. The high-performance flame-retardant ABS composite material comprises the following components in parts by weight: 28to 73 parts of ABS resin and 5 to 50 parts of POK polyketone resin, wherein the POK polyketone resin has a melt index of larger than 120 g / 10 min under the test conditions of 240 DEG C and 2.16 kg. According to the invention, the POK polyketone resin with specific structure is creatively alloyed with ABS, so the technical bottleneck problem of compatibility of a resin system is well solved, and mechanical properties of the material are greatly improved; meanwhile, due to advantages of the POK resin, the material has the characteristics of excellent weather resistance, solvent resistance, heatresistance and the like, so disadvantages of a conventional flame-retardant ABS alloy material are compensated, and great industrial application value is obtained. Meanwhile, the invention also provides a preparation method for the high-performance flame-retardant ABS composite material.

Description

technical field [0001] The invention belongs to the technical field of ABS composite materials, and in particular relates to a high-performance flame-retardant ABS composite material and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer composed of styrene, butadiene and acrylonitrile. It has the high fluidity of styrene, the toughness of butadiene and the chemical corrosion resistance of acrylonitrile. It has excellent processing performance, resistance Low temperature performance, electrical insulation performance, high gloss and excellent electroplating performance, as well as good creep resistance, high dimensional stability, small molding shrinkage, etc., are used in plastic products in the fields of household appliances, automobiles, electronic appliances, etc. very broad. [0003] The oxygen index of ABS resin is only 18%, the glow wire ignition temperature is only about 700°C, the vertical combustion can only reach HB level, and i...

AI Technical Summary

Problems solved by technology

[0003] The oxygen index of ABS resin is only 18%, the glow wire ignition temperature is only about 700°C, the vertical combustion can only reach HB level, and it is difficult to pass the needle flame test. These performance defects make it difficult to apply to some electrical appliances with high safety requirements. For products, only by developing a new flame-retardant technology through performance improvement and endowing materials with high flame-retardant properties can they meet the performance requirements of oxygen index, glow wire, and needle flame tests in product applications.
