Problems solved by technology

However, the crystallinity of PPS is greatly affected by the thermal history of the material, but still retains a high degree of crystallinity
Due to the relatively high crystallinity and the relatively low surface tension of the material, it is difficult to achieve a good adhesion effect when spraying paint, so it is very difficult to achieve spraying or electroplating on PPS products, so that it is difficult to meet products with very high appearance requirements.
Moreover, after glass fiber or carbon fiber reinforced PPS or mineral filled PPS, the appearance will also deteriorate, and the appearance effect of spraying will also be greatly affected

Abstract

The invention discloses a high-glossiness high-adhesion enhanced PPS composite material and a preparation method thereof. The high-glossiness high-adhesion enhanced PPS composite material comprises polyphenylene sulfide, a nucleating agent, a toughening agent, inorganic filler, a main antioxidant, an auxiliary antioxidant, a lubricating agent, a coupling agent and glass fiber. According to the invention, an ethylene methyl acrylate copolymer, an ethylene butyl acrylate copolymer and polyethylene octylene block copolymer grafted maleic anhydride are added into a composite material formula. Thestrength of the composite material is greatly enhanced by ethylene-methyl acrylate-glycidyl methacrylate (GMA).

Description

Technical field [0001] The invention relates to the technical field of modified polyphenylene sulfide resins, in particular to a high-gloss and high-adhesion reinforced PPS composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a new type of polymer material that can be used in harsh environments for a long time. It not only has high temperature resistance (long-term use temperature is 200-220℃), and chemical resistance (hardly soluble in any solvent at 200℃) ), good flame retardancy (LOI> 35), easy to process and other characteristics, and has good dimensional stability and superior mechanical properties. In the plastics industry, PPS is recognized as the sixth largest after polyamide (PA), polyoxymethylene (POM), polycarbonate (PC), modified polyphenylene ether (MPPO), and thermoplastic saturated polyester (PBT / PET) Engineering plastics are widely used in fields such as automobiles, petrochemicals, electronic applia...
