Abstract

The invention relates to a high-strength and flame-retardant polycarbonate composite and a preparation method thereof, and solves the problem that the conventional polycarbonate composite cannot integrate high flame retardance and high strength. The high-strength and flame-retardant polycarbonate composite is prepared from 50-90 parts of polycarbonate, 1.0-1.5 parts of polyisobutene, 1.0-5.0 partsof a phosphorus-based halogen-free flame retardant, 0.5-0.8 parts of phosphorus-containing maleimide ester, 2.0-3.0 parts of hydrotalcite powder, 10-15 parts of condensed polynuclear aromatic resin,2.0-4.0 parts of a nitrogen flame retardant, 1.0-2.0 parts of sodium perfluorooctanesulfonate, 0.5-0.7 parts of kaolin, 0.01-10 parts of an anti-drip agent, 2.0-4.0 parts of glass fiber, 3.0-5.0 partsof an impact modifier, 5.0-8.0 parts of a flexibilizer and 1.0-1.5 parts of an antioxidant; the raw materials are mixed in proportion and subjected to extrusion and granulation. The polycarbonate composite has high flame retardance and bending strength.

Description

technical field [0001] The invention relates to a high-strength flame-retardant polycarbonate composite material and a preparation method thereof, belonging to the technical field of flame-retardant polymer materials. Background technique [0002] Polycarbonate (PC) is one of the five most widely used engineering plastics. It has high impact resistance and heat resistance, and is widely used in electronics, electrical appliances, automobiles, aerospace and other fields. In recent years, with the expansion of the application field and production scale of polycarbonate, people have higher and higher requirements for its performance, especially for the flame retardancy and strength performance of the material. However, due to the PC material itself Generally, the flame retardant performance can only reach the V-2 level in the UL94 standard, and only has certain flame retardant characteristics. With the application requirements of various industries, this flame retardant level i...
