A kind of ABS/ oyster shell whiting matrix material, it is obtained by the raw material of following weight parts:

ABS resin 40-80, oyster shell whiting 5-15, coir fibre 3-5, stearoyl lactate 0.5-1, maleic anhydride 4-6, Viscotrol C 2-4, dibenzoyl peroxide 0.02-0.04, vinylbenzene 6-8, aluminate coupling agent 0.05-0.1, antioxidant 1010 0.2-0.5, hydrogenated lanolin 2-4.

A preparation method for ABS/ oyster shell whiting matrix material, comprises the following steps:

(1) oyster shell whiting is calcined 1-2h under 800-900 DEG C of condition, add coir fibre 100-120 DEG C of process 1-2h after cooling, be ground to 300-400 order, obtain mixed powder;

(2) prior to grinding 3-5h under 60-80 DEG C of condition after the mixed powder in (1) being mixed with maleic anhydride, mix with vinylbenzene and appropriate dimethylbenzene again and jointly add reactor, insulated and stirred process 2-4h under first 80-90 DEG C of condition, 6-10h is stirred under adding dibenzoyl peroxide similarity condition again, cool and filter, wash, after vacuum-drying completely active powder;

(3) active powder in (2) is uniformly mixed 1-2h with aluminate coupling agent, Viscotrol C and hydrogenated lanolin under 100-110 DEG C of condition, obtains modified filler;

(4) ABS resin is mixed 5-10min with the modified filler in (3) and all the other raw materials in premixing machine, obtain mixture;

(5) added in twin screw extruder by the mixture in (4) and melt extrude granulation, obtain ABS composite material, wherein twin screw extruder extrusion temperature is 210-230 DEG C.

Advantage of the present invention is:

By oyster shell whiting, coir fibre is composite as filler, carry out surface recombination modified by maleic anhydride and cinnamic graft copolymerization to it, its toughness of effective lifting, improve fracture property and the tensile property of material, and in conjunction with the further modification of aluminate coupling agent etc., improve filler intensity and with the affinity of matrix resin and bonding force, it is made to be dispersed in matrix, the weathering resistance of material and physical strength are played a role in improving, thus make the matrix material obtained have excellent mechanical property, corrosion resistance, high thermal resistance and weathering resistance, and it is wear-resistant, surface gloss is high, stable performance, there is certain elimination peculiar smell simultaneously, the effect purified air.
