Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyphenylene sulfide laminated composite board and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a new type of high-temperature resistant thermoplastic engineering plastic. It not only has high strength and good dimensional stability, but also has excellent chemical resistance, flame retardancy and good processing properties. , Is a special engineering plastic that can be used for a long time under high temperature conditions. However, due to the existence of a large number of benzene rings on the PPS main chain, the rigidity of the polymer chain is increased, making it brittle and low in impact toughness, so it is limited in its application. [0003] Chinese Patent 101386218 B discloses a manufacturing method of polyphenylene sulfide fiber composite laminate sheet. The method adopts the sequential stacking of A-layer / B-layer unit...

However, due to the presence of a large number of benzene rings in the main chain of PPS, which increases the rigidity of the polymer chain, making it brittle and not high in impact toughness, it is limited in application.

[0003] Chinese patent 101386218 B discloses a method for manufacturing polyphenylene sulfide fiber composite laminated boards. The method adopts A-layer / B-layer unit structures to be laminated sequentially to form a composite layer. Medium-melt thermocompression molding; Chinese patent CN101148107 A discloses a manufacturing method of high-performance polyphenylene sulfide fiber laminates, which uses sodium sulfide and p-dichlorobenzene as raw materials to synthesize polyphenylene sulfide resin, and then melt-spun The finished fiber is obtained by spinning and hot drawing, and the finished fiber resin composition is laminated with other thermoplastic resins to prepare a high flame-retardant fiber laminate; the polyphenylene sulfide fiber laminate prepared by the above method has both good properties. Mechanical properties and excellent properties of polyphenylene sulfide, but there are also some shortcomings, such as weak bonding between fiber layers, poor melt impregnation effect between fibers and resin, etc., which cannot meet higher standard performance requirements
