Abstract
The invention discloses a bicyclic caged phenyl phosphate silicone modified flame-retardant PC/ABS (polycarbonate/acrylnitrile-butadiene-styrene) alloy and a preparation method thereof. The flame-retardant PC/ABS alloy is prepared from the following raw materials in percentage by mass: 55-60% of polycarbonate, 20-25% of an ABS copolymer, 7-9% of phosphate, 5-7% of bicyclic caged phenyl phosphate silicone, 5-7% of a polydimethylsiloxane-styrene-methyl methacrylate copolymer, 0.3-0.5% of an anti-dripping agent and 0.2%-0.4% of an antioxidant. The flame retardant rating of the flame-retardant PC/ABS alloy disclosed by the invention is UL94V-0@1.6mm, the heat deflection temperature is above 92 DEG C, the notched impact strength is above 31kJ/m<2>, and the melt flow rate is above 16g/10min. The flame-retardant PC/ABS alloy has the advantages of high flame retardant rating, good heat resistance, excellent mechanical properties and good processing fluidity.
Description
technical field [0001] The invention relates to a flame-retardant polycarbonate / styrene-butadiene-acrylonitrile copolymer (PC / ABS) alloy material, in particular to a double-ring cage-shaped phosphate ester siloxane flame-retardant PC / ABS alloy material and its preparation The method belongs to the technical field of polymer material modification. Background of the invention [0002] PC has the advantages of high impact strength, thermal stability and insulation performance. ABS has good chemical resistance and excellent forming and processing performance. The PC / ABS alloy obtained by blending the two has the advantages of both. It has good comprehensive performance, so it is widely used in the manufacture of electrical and electronic parts and auto parts. Because such applications require high heat resistance, flame retardancy and mechanical strength of materials, and PC / ABS alloys have poor flame retardancy, especially alloys with a high proportion of ABS are easy to burn,...
