Abstract

The invention belongs to the technical field of high-polymer alloy materials, and relates to a phosphate flame-retardant PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) alloy and a preparation method thereof. The alloy material is prepared from the following components in parts by weight: 55-75 parts of PC resin, 25-45 parts of ABS resin, 2-10 parts of compatilizer, 2-10 parts of toughening agent, 10-20 parts of flame retardant, 2-10 parts of inorganic filler, 0.1-0.5 part of antioxidant, 0.2-1.0 part of lubricant and 0.2-1.0 part of anti-dripping agent. The compatilizer, toughening agent and inorganic filler are utilized to enhance the interfacial binding force between the PC resin and ABS resin and the mechanical properties of the PC/ABS alloy. Besides, the nano silicon dioxide and other inorganic fillers added into the PC/ABS alloy can effectively perform the synergic flame-retardant function; and the anti-dripping agent in the formula can effectively inhibit the melt from dripping in the alloy material combustion process, thereby enhancing the flame retardancy of the material.

Description

technical field [0001] The invention belongs to the technical field of polymer alloy materials, and relates to a phosphate ester flame-retardant PC / ABS alloy and a preparation method thereof. Background technique [0002] Since the successful development of PC / ABS alloy by Borg Warner Company of the United States in 1963, it has rapidly become popular in the world. In 2003, the world's total alloy production exceeded 700,000 tons. In the past five years, the output of PC / ABS alloy has been growing at a rate of about 10% every year. The growth rate ranks in the forefront in the field of plastics. It has become the largest commercial polymer alloy in the world and is widely used in the automotive industry. , household appliances and office equipment and other fields. In order to meet the fire safety requirements in the application field, PC / ABS alloy must have good flame retardancy. [0003] At present, the flame retardants used for PC / ABS alloys mainly include brominated f...
