Water-borne antirust coating having good heat dissipation and applied to pump valve

Abstract

The invention discloses a water-borne antirust coating having good heat dissipation and applied to a pump valve. The water-borne antirust coating is prepared from raw materials in parts by weight as follows: 65-70 parts of methyl methacrylate, 60-65 parts of styrene, 0.5-0.6 parts of ammonium persulfate, 4-5 parts of phosphate ester monomers, 20-24 parts of deionized water, 2-3 parts of SDS (sodium dodecyl sulfate), 35-40 parts of glass flakes, 1-1.2 parts of a silane coupling agent KH560, 30-35 parts of an ethanol solution with the concentration of 75wt%, 40-43 parts of a sodium hydroxide solution with the concentration of 10wt%, 2-3 parts of isopropanol, 3-4 parts of catechol, 0.7-0.8 parts of alkylphenol polyoxyethylene alcohol, 3-4 parts of zinc phosphate, 12-14 parts of aluminum nitride, 3-4 parts of heat conducting silicone grease, 10-12 parts of zinc oxide, 1.5-2 parts of dimethicone and proper amount of water. The prepared coating can release high temperature caused by work after being sprayed to the surface of a pump valve material and has excellent heat dissipation effect and mechanical properties, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based antirust coating with good heat dissipation for pump valves. Background technique [0002] The working environment of the pump and valve is diverse and harsh, and the requirements for the material are very high. At present, the materials used for the pump and valve are various, and the technology has made great progress, but there are still many problems, especially when it is used to transport liquids. The anti-rust performance of the valve is very high, and ordinary paints often cannot meet the needs of the environment, which requires the modification of the coatings for multi-pump valves, so as to prepare more suitable coatings for pump valves. [0003] In order to ensure the anti-corrosion quality of the coating, the traditional anti-corrosion coating needs to carry out a thorough surface treatment on the steel by certain means before construction.

Problems solved by technology

[0002] The working environment of the pump and valve is diverse and harsh, and the requirements for the material are very high. At present, the materials used for the pump and valve are various, and the technology has made great progress, but there are still many problems, especially when it is used to transport liquids. The anti-rust performance of valves is very high, and ordinary paints often cannot meet the needs of the environment, which requires the modification of coatings for multi-pump valves, so as to prepare more suitable coatings for pump valves

[0003] In order to ensure the anti-corrosion quality of the coating, the traditional anti-corrosion coating needs to carry out a thorough surface treatment on the steel by certain means before construction. The cost of the traditional surface treatment process accounts for about 30%-40% of the total cost of coating. The cost of the paint itself only accounts for about 19%, and traditional surface treatment methods are prone to produce a lot of dust pollution and noise pollution, especially in some special occasions such as complex steel structure dead corners that cannot even be surface treated by traditional sandblasting methods. Therefore, it is of great significance to find a treatment method that is more environmentally friendly and cost-effective.
