Abstract

The invention discloses a basalt fiber enhanced environment-friendly flame-retardant ABS composite material. The composite material is prepared from, by weight, 100 parts of acrylonitrile-butadiene-styrene copolymers, 20-40 parts of basalt fibers, 0.2-1 part of coupling agent, 0.1-8 parts of flexibilizer, 10-20 parts of flame retardant, 2-10 parts of flame-retardant synergist, 1.5-2 parts of antioxidant, 1-1.5 parts of light stabilizer, 10-20 parts of heat-resisting auxiliaries, 0.5-1.0 part of dispersant and 4-10 parts of interfacial compatibilizer. Preferably, the basalt fibers are treated through 0.2-1 part of the coupling agent by weight before the basalt fibers are used and then immersed in 4-10 parts of the compatibilizer by weight. The invention further discloses a preparation method of the composite material. The basalt fibers and an ABS matrix in the composite material have the good bonding effect, so that the composite material has good strength, rigidity and impact toughness, and meanwhile has the advantages of being resistant to inflaming, good in heat resistance, easy to process, long in service life and low in cost.

Description

technical field [0001] The invention belongs to the field of ABS composite materials, in particular to a high-strength basalt fiber reinforced flame-retardant and environment-friendly ABS composite material and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-butadiene-styrene copolymer) is a thermoplastic composed of three components: acrylonitrile, butadiene and styrene. It is a two-phase structure polymer material in which the polybutadiene rubber phase is dispersed in the continuous phase of AS resin. ABS is widely used in machinery, household appliances, daily appliances and other industries due to its good rigidity, hardness, toughness, chemical resistance and processing fluidity, low cost and light weight. The characteristics of the three components that make up the resin, namely the gloss and formability of styrene, the excellent mechanical properties of acrylonitrile, the impact resistance of polybutadiene rubber, etc., the effective c...
