Problems solved by technology

But there is the defect that the impact strength is not high in the composite material of this invention, and the scope of application is also limited simultaneously
[0004] Chinese patent CN: 1272124A introduces the manufacture method of the polyphenylene sulfide (PPS) composite material that adopts zinc oxide whisker and glass fiber or carbon fiber and polyphenylene sulfide (PPS) resin to carry out blending modification, and its purpose is to adopt Zinc oxide is used as a corrosion inhibitor to improve the corrosion of metals and eliminate the adverse effects on mechanical and physical properties; however, after adding zinc oxide, the tensile strength and fracture of polyphenylene sulfide (PPS) composites made of injection molding The elongation is reduced, and its impact strength is also reduced

Embodiment 1

[0012] Add polyphenylene sulfide resin with a molecular weight of 20,000 to 80,000 into a thermal crosslinking machine, control the temperature between 200-260°C, and conduct thermal crosslinking for 2-8 hours. The polyphenylene sulfide resin of 30% by the total mass of the product (the following are based on the total mass of the product), 0.1% cyclohexanemethanol polyoxystyrene ether phosphate ester amine salt and 1% styryl triethoxysilane, 0.1% metazincic acid, 30% alumina ceramic powder (90% particle size 10um content), and 0.5% antioxidant GK-1098 were stirred evenly in a high-speed mixer. Then add 30% of the glass fiber treated with the KH550 surface treatment agent and the rest of the cross-linked polyphenylene sulfide resin, so that the polyphenylene sulfide composite material reaches 100% of the total product quality. Twin-screw extruder for mixing and extrusion, cooling, pelletizing and packaging.

Abstract

The invention discloses a manufacturing method of polyphenyl thioether ceramic powder alloy compound particles. Polyphenylene sulfide resin is processed through oxidation heat crosslinking accounting for 30 percent to 40 percent of the total mess percentage of the product, white ceramic powder as filling agent accounting for 30 percent to 35 percent, fatty alcohol polyphenylene oxide vinyl ether phosphate ester amine salt as heat stabilizer accounting for 1 percent to 5 percent and zincic acid as anti-corrosion inhibiting agent accounting for 0.1 percent to 5 percent are added into the polyphenylene sulfide resin and are fully and evenly mixed in high speed agitator, then glass fibers with the surface processed through KH550 surface treating agent accounting for 30 percent are added, the mixture is extruded, formed, cooled and cut into finished product composite particles through the compounding of a double screw extruder. The composite particles obtained by adopting the manufacturing method of the invention have the advantages of high thermal denaturation stability and tensile strength and low metal corrosion rate. The manufacturing method can be widely applied to the fields of the electronic equipments, the machinery, the chemical industry, the petroleum, the military industry and the aerospace and aviation.

Description

Technical field [0001] The invention belongs to the application field of special polymer materials Background technique [0002] Polyphenylene sulfide (PPS) has excellent thermal stability, has excellent high temperature resistance, and has a melting point of 285°C, which is higher than other special engineering plastics currently produced industrially. PPS composite pellets have excellent injection processing performance and can be processed into various Various specifications and shapes of PPS composite products. However, in some fields with more demanding application conditions, it is still the goal that people pursue to explore and discover PPS composite materials with better performance. [0003] In Chinese Patent No. CN: 1462771A, a method of manufacturing a polyphenylene sulfide (PPS) composite material that polyphenylene sulfide (PPS) resin is blended and modified with a kind of nanometer material and glass fiber is introduced, through such Modification improves it...
