Flame-retarding polyphenyl ether composite, and preparation method and use thereof

Abstract

The invention discloses a flame-retarding polyphenyl ether composite, and a preparation method and use thereof. The flame-retarding polyphenyl ether composite comprises the following components in percentage by weight: 18 to 28 percent of polyphenyl ether, 5 to 30 percent of acrylonitrile-styrene copolymer, 20 to 35 percent of elastomer, 20 to 35 percent of fire retardant, 5 to 18 percent of plasticizer, and 0.1 to 1.5 percent of antioxygen. The composite can be prepared by the following steps: dispersing and mixing the polyphenyl ether, acrylonitrile-styrene copolymer, elastomer, fire retardant, plasticizer and the antioxygen in a high-speed mixer; melting, blending and extruding in a double-screw extruder; and cooling, drying, granulating and packing. The composite is free from halogen and flame-retarding, and has high mechanical performance, electrical performance and heat resistance. It is easy to print the surface of the composite. And the composite is very suitable for preparingpower wires, data transmission wires and the like of electronic appliances.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant polyphenylene ether compound and its preparation method and application. Background technique [0002] Halogenated compounds such as polyvinyl chloride (PVC) and neoprene have excellent flame retardant properties and are widely used in the wire industry, but they will produce a large amount of toxic gases during fire or incineration, which will cause great damage to the human body and the environment. In recent years, some non-governmental environmental protection organizations have actively called on major electronic and electrical manufacturers to remove PVC materials and halogen-containing flame retardant materials from their products. Major companies are also actively looking for non-halogenated materials to replace PVC, making The development of halogen-free flame-retardant soft materials is increasingly urgent. [0003] At present, there are many composit...
