Abstract

The invention discloses a bacteria-resistant polyphenylene ether and nylon alloy material and a preparation method thereof. The material is composed of the following components in parts by weight: 20to 60 parts of polyphenylene ether resin, 20 to 50 parts of nylon resin, 3 to 10 parts of a compatibilizer, 5 to 10 parts of a toughening agent, 5 to 10 parts of a silver ion antibacterial agent, and0.1 to 1 part of an antioxidant. The bacteria-resistant polyphenylene ether and nylon alloy material has excellent properties which cannot be achieved by multiple common materials, and has the main features of excellent processing performance, high impact resistance and excellent bacteria resistance. The bacteria-resistant polyphenylene ether and nylon alloy material has the advantages of polyphenylene ether and nylon, overcomes the disadvantages of poor processing property and poor impact resistance of polyphenylene ether, has bacteria resistance and broadens the field of application of polyphenylene ether.

Description

technical field [0001] The invention relates to a bacteria-resistant polyphenylene ether and nylon alloy material and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Polyphenylene ether (PPO) resin is one of the five general-purpose engineering plastics. It has the advantages of high rigidity, good heat resistance, good flame retardancy, and high strength, but its impact performance is poor, and its poor fluidity is difficult to process, which limits its use in applications in certain fields. Nylon resin has good heat resistance, good fluidity and easy processing. The polyphenylene ether / nylon alloy obtained by blending polyphenylene ether and nylon has both the unique advantages of both polyphenylene ether and nylon. At present, the attention of polyphenylene ether / nylon materials at home and abroad is mainly focused on the automotive industry, reducing gasoline consumption, reducing toxic gas emissions, e...
