Abstract

A composite material modified with nanometer calcium carbonate and used for valve sealing is disclosed. The composite material comprises 60-80 parts by weight of the nanometer calcium carbonate, 20-35 parts by weight of nanometer ceramic powder, 15-20 parts by weight of nanometer titanium dioxide, 20-30 parts by weight of nanometer silicon carbide, 10-18 parts by weight of boron carbide, 6-10 parts by weight of nanometer bentonite, 5-8 parts by weight of talcum powder, 25-30 parts by weight of polytetrafluoroethylene, 20-30 parts by weight of polyurethane resin, 12-16 parts by weight of sodium carboxymethylcellulose, 8-12 parts by weight of glycerol, 8-10 parts by weight of linear type phenol formaldehyde resin and a plurality of auxiliary agents. The composite material can form a dense and hard coating on the surface of a metal valve and plays roles of high strength, high wear resistance, high-temperature resistance, corrosion resistance and ageing resistance, thus improving sealing performance of the valve, effectively prolonging the service lifetime of the metal vale, and broadening the using range of the metal valve.

Description

technical field [0001] The invention relates to the technical field of valve sealing materials, in particular to a nano calcium carbonate modified composite material for valve sealing and a preparation method thereof. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Therefore, the paint sprayed on the surface of the valve must have water resistance, impact resistance, heat resistance, heat insulation and other properties, especially the paint sprayed on the surface of the metal valve needs to have strong anti-corrosion and oxidation resistance. [0004] However, there are few coatings dedicated to metal valves in the market at present, and their anti-corrosion and anti-oxidation effects are relatively poor. [0005] At present, the non-metallic sealing materials comm...
