Method for manufacturing composite-material electromagnetic valve

Abstract

The invention provides a method for manufacturing a composite-material electromagnetic valve. The method comprises the following steps of selecting a high-strength carbon fiber, wherein the high-strength carbon fiber is in T300-T700 grade or higher, the carbon content of the high-strength carbon fiber is 93-95%, the elastic modulus is 220Gpa, and the length is 3-5mm; adding 45 parts by weight of high-strength carbon fiber, 35 parts by weight of an unsaturated resin, 15 parts by weight of an acetone curing agent and 5 parts by weight of a nano-scale carbon fiber material into a container, and agitating uniformly by using a mechanical agitator; injecting the carbon-fiber composite material obtained by agitating the components uniformly into a mold, heating at the temperature of 120-200 DEG C, molding for 50 minutes, decreasing the temperature to room temperature, removing the mold, compacting and calcining for 2-3 times, and electroplating the surface of the product or spraying plastics on the surface of the product. The electromagnetic valve manufactured from the composite material is light in weight and has high strength, good compression resistance and corrosion resistance and long service life.

Description

technical field [0001] The invention relates to the application field of composite materials, in particular to a manufacturing method of a composite material electromagnetic valve. Background technique [0002] Valves are widely used in all walks of life. The improvement of valve materials and quality has further improved the modernization and automation of the equipment manufacturing industry, and improved the level, performance and functions of the industry and all walks of life. However, the current valve industry is all about castings and castings. Steel and non-ferrous metals, etc., and anti-corrosion valves are made of high-quality non-ferrous anti-corrosion materials. Because the functionality, applicability and necessity of valves are widely used, the amount of steel and rare metals consumed is also increasing sharply. While the increase in steel and rare metals also increases the weight of the overall equipment, the weight of the overall equipment is increased Will...

Problems solved by technology

Because the functionality, applicability and necessity of valves are widely used, the amount of steel and rare metals consumed is also increasing sharply. While the increase in steel and rare metals also increases the weight of the overall equipment, the weight of the overall equipment is increased Will bring a lot of energy consumption and resource shortage

Due to the high pressure of the valve, the manufacturing material of the valve needs to have high strength, and the material used must have a product safety factor, which needs to be durable. Due to the high proportion of steel, it is difficult to reduce the weight of the overall equipment. If a new type of valve can be developed The specific gravity of the material can be small, which can effectively reduce the overall weight, improve the performance, and has anti-corrosion function, which will bring a qualitative leap to the field of materials and manufacturing
