Special sealing grease for sanitary valves and preparation method thereof

Abstract

The invention discloses special packing grease for sanitary valves. The grease is prepared from the following raw materials according to percentage by weight: synthetic base oil with ultra high viscosity, a hydrated magnesium silicate inorganic thickener, an antioxidant, a phosphoric acid phenolic ester type extreme pressure agent and an adhesive, wherein the synthetic base oil with ultra high viscosity, the adhesive and the unique hydrated magnesium silicate inorganic thickener ensure excellent water flushing resistance for the packing grease; the unique hydrated magnesium silicate inorganic thickener and the high-quality synthetic base oil are treated by a special process to guarantee the long-term shearing resistance of the packing grease; the special waterproof extreme pressure anti-wear agent is adopted to ensure the excellent lubricity of the packing grease under an environment with a large amount of water. The special packing grease for sanitary valves disclosed by the invention can be used for solving the water flushing resistance problem of the packing grease of valves and prolonging the service life of the packing grease, and the packing grease can have the same service life as the valves and can ensure the sealing property and lubricity of the valves after being opened and closed for 300000-500000 times, so that the sanitary valves are free of water seepage phenomenon so as not to generate influence or pollution on water quality.

Description

technical field [0001] The invention relates to the field of sealing lubrication, in particular to a special sealing grease for sanitary valves. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, diversion or overflow pressure relief. Valves can be used to control air, water, steam, various corrosive media, mud, etc. , oil, liquid metal and radioactive media and other types of fluid flow. The sealing performance of the valve is directly related to the quality of the valve, and the sealing material is one of the key factors to ensure the sealing performance of the valve. Especially for bathroom valves, because they are in the water shower environment for a long time, the switch has reached 300,000 to 500,000 times, so the requirements for sealing and lubricity are higher. Shearing, and will not cause pollution and impact o...

Problems solved by technology

When the traditional sealing grease is used for bathroom valves, it often has poor water resistance. After a long time of use, the shear resistance becomes worse and worse, causing water seepage in the bathroom valves. The service life is short, and the grease needs to be replaced continuously. Large replacement rate, increased waste and not environmentally friendly
