Abstract

The invention provides a polyphenylene oxide resin composite material which comprises the following ingredients in parts by weight: polyphenylene oxide resin, an elastomer, a fire retardant, polyolefin, functional master batches, a primary antioxidant and an auxiliary antioxidant, wherein the 10% total weight of the functional master batches comprise the following ingredients by weight percentage:60-79% of resin binders, 20-39% of gas phase nano-silica with a branch structure and 1-3% of a coupling agent; the coupling agent is coated on the surface of the gas phase nano-silica with the branchstructure. On the basis that the excellent property of the polyphenylene oxide resin can be effectively maintained, the polyphenylene oxide resin composite material provided by the invention also hasexcellent high temperature and high pressure resistance and has obviously improved toughness and stress cracking resistance.

Description

Technical field[0001]The invention belongs to the technical field of polymer materials, and particularly relates to a polyphenylene ether resin composite material and a preparation method thereof.Background technique[0002]Polyphenylene ether resin alloy has many excellent properties, such as high modulus, high temperature resistance, creep resistance, self-flame retardant, etc., and is widely used in electronic appliances, auto parts, communication photovoltaics and other fields. The polyphenylene ether resin with the above-mentioned properties is also suitable for making valves for cold and hot water supply pipes. However, because polyphenylene ether materials have low impact strength, poor toughness, and poor resistance to stress cracking, they are prone to stress cracking when used in water pipe valves, which limits the application of polyphenylene ether materials in the field of water pipe valves.Summary of the invention[0003]The purpose of the present invention is to provide a ...
