| titleOfInvention | Preparation method of flame-retardant micro-foaming polyphenyl ether composite material and product thereof |
| abstract | The invention discloses a preparation method of a flame-retardant micro-foaming polyphenyl ether composite material, which comprises the following steps: A. blending 10-90 parts by weight of polyphenyl ether, 10-90 parts by weight of high impact polystyrene, 1-50 parts by weight of organic phosphorus flame retardant and 1-50 parts by weight of inorganic hypophosphite, and carrying out mixing and hot pressing to obtain a prefabricated product; B. and C, placing the prefabricated product prepared in the step A into a high-pressure kettle, introducing foaming gas, and foaming by adopting a heating foaming method after the prefabricated product reaches the saturation pressure to obtain the flame-retardant micro polyphenyl ether composite material. The preparation method disclosed by the invention is simple and safe in process, high in efficiency, green and environment-friendly; the prepared polyphenyl ether composite material has high expansion rate and excellent flame retardant property. |
