Abstract

The invention discloses a flame-retardant toughening type PC composite material and a preparation method thereof. The flame-retardant toughening type PC composite material comprises the following components in percentage by mass: 60-80 percent of PC, 10-15 percent of flame retardant, 10-15 percent of a toughening agent, 5-10 percent of organic montmorillonite, 1-4 percent of a compatilizer, 0.1-0.5 percent of antioxidant, and 0.1-2 percent of other auxiliaries. Compared with the prior art, the flame-retardant toughening type PC composite material has the benefits of high flame retardency ( the oxygen index can reach more than 32), high impact-resistant efficiency, high heat stability, high strength, high electric performance, low cost and the like, is simple in processing procedures and easy for industrial production, and has a good application prospect in the industries of automobiles, electric appliances, mechanical components, material construction and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant and toughened PC composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a kind of engineering plastic with excellent comprehensive performance, excellent impact performance and stable size, so it is more and more widely used in the fields of electrical insulation transportation, instrumentation and electrical lighting. But it has some serious shortcomings, such as: poor processing performance, easy stress cracking, sensitive notch resistance, poor chemical resistance, low flame retardancy (oxygen index is 21% to 24%), etc. Therefore, modifying PC is an effective way to make up for its lack of performance, achieve high performance, reduce production costs and broaden application fields. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant and toughened...
