Problems solved by technology

However, PPS also has some disadvantages: 1. It is very easy to flow, and it is difficult to inject molding with pure resin; 2. The surface of the glass fiber reinforced and filled product is rough and the gloss is poor; 3. The cost is high, and the price is higher than that of general engineering plastics. twice; 4. The impact strength is poor, the product is brittle, and the welding strength is not good; 5. Because PPS has excellent chemical resistance, its coating and coloring properties are not ideal
[0003] Polyphenylene ether (PPO) is an amorphous material with very good dimensional stability, excellent mechanical properties, and dense surface, but polyphenylene ether (PPO) has the disadvantages of poor fatigue resistance and poor stress crack resistance when used alone, and Its temperature resistance grade is below 150°C, which is lower than that of polyphenylene sulfide (PPS)

Abstract

The invention discloses a fiberglass enhanced polyphenyl thioether / polyphenylether composite material and a preparation method thereof. The composite material is mainly prepared by the following raw materials: polyphenyl thioether, polyphenylether, fiberglass, mineral filler, a compatibility agent, an antioxidant and a processing aid. The preparation method of the fiberglass enhanced polyphenyl thioether / polyphenylether composite material comprises the following steps of: (a) firstly, respectively blasting and drying polyphenyl thioether resin and polyphenylether resin; (b) weighting the polyphenyl thioether resin and the polyphenylether resin which are dried, the mineral filler, the compatibility agent, the antioxidant and the processing aid; (c) mixing the dry materials in the step (b) to obtain a compound; and (d) adding the compound in the step (c) and the fiberglass to a double screw extruder for melt blending and pelleting. The fiberglass enhanced polyphenyl thioether / polyphenylether composite material can unconspicuously lower the temperature-resistant level and the rigidity of the polyphenyl thioether resin, further improve the molding accuracy of the polyphenyl thioether resin and decrease the cost.
