Abstract

The invention relates to the technical field of alloy materials, particularly a novel polyphenylene oxide alloy which comprises the following components in parts by mass: 20-30 parts of polyphenylene oxide resin, 5-12 parts of phosphate, 15-23 parts of polyethylene terephthalate, 3-9 parts of polytetrachloroethylene, 3.5-4.2 parts of polymethyl methacrylate, 35-40 parts of nylon resin, 4-10 parts of maleic acid and 8-15 parts of polystyrene resin. By adopting the formula, the polyphenylene oxide alloy material has favorable heat stability, can keep the physical dimensions constant, and can not generate the phenomena of stress cracking and the like. Besides, the material has higher heat resistance, and the oil resistance and solvent resistance are greatly improved.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a novel polyphenylene ether alloy. Background technique [0002] Unmodified polyphenylene ether resin has good mechanical properties, electrical properties, heat resistance, flame retardancy and chemical stability, etc., but its solvent resistance is poor, the product is prone to stress cracking, and the notched impact strength is low. It has a fatal weakness—high melt viscosity, poor processability, and pure polyphenylene ether resin cannot be molded by injection, which greatly limits its application. In order to overcome these shortcomings, or endow it with new properties, people have carried out various modifications to polyphenylene ether resin. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel polyphenylene ether alloy with superior performance. [0004] In order to solve the above-mentioned techn...
