Abstract

The invention discloses a method for manufacturing a polyphenylene sulfide composite film. The method comprises the following steps of: performing polycondensation under the action of an alkaline metal cosolvent by taking sodium sulfide and paradichlorobenzene as raw materials and N-methyl-2 pyrrolidone as a solvent so as to produce a polyphenylene sulfide resin, wherein the molar ratio of the sodium sulfide and the paradichlorobenzene is 1:1; and synthesizing polyphenylene sulfide under a certain condition, refining, purifying, washing and drying the polyphenylene sulfide to obtain the polyphenylene sulfide resin, adding a mixture comprising 1.5 to 0.9 percent of heat stabilizer, 8.5 to 4.1 percent of organic elastomer and the like into 90 to 95 percent of resin, extruding and pelletizing by a double-screw extruder, drying and performing a film preparation process so as to obtain a polyphenylene sulfide resin film. The film obtained by the method can be widely applied to fields such as electronic and electric products, war industry, space flight and aviation, machinery, chemical industry and the like.

Description

Technical field [0001] The invention belongs to the field of polymer products, especially composite film manufacturing. Background technique [0002] With the advancement of science and technology and the development of society, the development and application of new technologies and new materials have become more and more extensive, and the requirements for electronic and electrical insulation materials have become higher and higher, especially those with high temperature heat resistance and hydrolysis resistance. Electrical insulating materials are also new materials with very low water absorption and moisture absorption. [0003] The high-performance polyphenylene sulfide film has excellent chemical resistance and thermal stability at high temperatures, and has flame retardant, insulation, radiation resistance and good mechanical properties. In order to explore the application method of this material, researchers from various countries have been constantly seeking for it. [000...
