Abstract

The invention discloses a flame-retardant PP / ABS (propene polymer / acrylonitrile butadiene styrene) composite material and a preparation method thereof. The composite material is prepared from the following components in parts by weight: 63-70 parts of PP resin, 27-33 parts of ABS resin, 0.1-0.4 part of crosslinker, 1-4 parts of assistant crosslinker, 0.1-0.5 part of antioxidant, 10-25 parts of fire retardant and 1-3 parts of flame-retardant synergist. The composite material prepared according to the invention has the advantages of excellent mechanical strength, good flame-retardant effect, low toxicity and low cost.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a flame-retardant PP / ABS composite material and a preparation method thereof. Background technique [0002] The price of styrene-butadiene-acrylonitrile copolymer (ABS) is higher than that of ordinary plastics, which limits the wide application of ABS to a certain extent. Although the overall performance of polypropylene (PP) plastics is not as good as that of ABS resins, PP has heat resistance. It has better fluidity and fluidity than ABS, is very stable to polar organic solvents, and can be used at a temperature of 100°C to 120°C. It is a cheap and light general-purpose plastic. Therefore, the development of ABS and PP blends can produce light and cheap plastic alloys on the one hand, and on the other hand can achieve complementary performance advantages, achieve the purpose of modification, and expand the application fields of ABS resin and PP pl...
