Abstract
The invention provides a matte spraying-free polycarbonate/acrylonitrile-butadiene-styrene alloy and a preparation method thereof in the technical field of the high polymer materials. The matte spraying-free polycarbonate/acrylonitrile-butadiene-styrene alloy is composed of the following components: 40-80 parts of PC-g-EVA (Ethylene-Vinyl acetate), 20-60 parts of ABS (Acrylonitrile Butadiene Styrene), 5-30 parts of ACS (Acrylonitrile Chlorinated-Polyethylene Styrene), 1-10 parts of silicon dioxide, 0.1-2 parts of antioxidant, and 0.05-1 part of thermal stability; the luster of the polycarbonate/acrylonitrile-butadiene-styrene alloy reaches 4-25Gu at 60 DEG C. The PC/ABS alloy achieves the matte effect by use of the characteristic that ACS and PC-g-EVA are incompatible; meanwhile, the inorganic powder silicon dioxide is added so that the PC/ABS alloy has the matte effect; ACS and silicon dioxide are used for achieving the synergetic matte effect. Meanwhile, as the alloy prepared by the preparation method contains EVA, the problem of low impact property of the inorganic powder modified matte PC/ABS is solved. Moreover, as ACS is added, the alloy materials has flame-retarding, anti-aging and weather-resisting characteristics.
