Problems solved by technology

[0006] Most of the existing valves are made of metal, but they will be corroded during long-term use, so that the valves cannot work normally. Some valves are protected by spraying, but the surface paint film is prone to peeling off due to aging, so it cannot be protected normally Valve

Abstract

The invention discloses a high-strength tire valve and a production process thereof. An aluminum alloy valve is sprayed with a reinforcing coating, and heat preservation is performed for 1-1.5 h at the temperature of 50-60 DEG C, so that the high-reliability corrosion-resistant valve is obtained. The reinforced coating is prepared from the following raw materials in parts by weight: 100 to 150 parts of acrylic emulsion, 10 to 15 parts of reinforcing filler, 10 to 15 parts of talcum powder, 10 to 15 parts of propylene glycol butyl ether, 1 to 5 parts of dispersing agent, 10 to 20 parts of plasticizer and 50 to 80 parts of water. A reinforcing filler is prepared in the process of preparing the reinforcing coating, the reinforcing filler takes modified graphene as a carrier, the modified graphene can enhance the corrosion resistance of a coating film, and a large number of hindered phenol and phosphite structures exist on the surface, so that hydroperoxide can be eliminated, and a coating film is not prone to aging; and the long-time protection of the coating film on the inflating valve is ensured.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-strength tire valve and a production process thereof. Background technique [0002] The valve is an independent valve body device that allows gas to enter the space of a tubeless tire or inner tube when it is opened, and then automatically closes and seals the gas to generate air pressure to prevent the gas from escaping the tire or inner tube, except for solid tires. Outside the tire, other tires or inner tubes that must be inflated need to be inflated with this device, and the tire valve is used to inflate the tire with gas or liquid, and it is a one-way valve that can maintain and detect the internal pressure. There are inner tube tires installed on the inner tube. Tubeless tires are installed on the rim, and can be divided into rubber metal valves and metal valves with rubber pads according to the structure. The former is used for car tire inner tubes, and the latter is...
