AI Technical Summary

Problems solved by technology

Due to the poor hydrophilicity of the metal anti-corrosion coating, after the anti-corrosion coating is applied on the surface of the metal wet curtain of the air-conditioning fan, the hydrophilicity of the surface needs to be modified, usually by adding a layer of inorganic hydrophilic film on the surface of the anti-corrosion coating , but the adhesion of the inorganic hydrophilic film on the surface of the organic anti-corrosion coating is poor, so the general organic anti-corrosion coating is not suitable

Abstract

The invention discloses an anticorrosive paint, a preparation method, and application of the anticorrosive paint in an air conditioner fan metal wet curtain. The anticorrosive paint composition is prepared from the following components in percentage by weight: 10 to 30 percent of rare earth compound, 70 to 85 percent of oxysalt, 1 to 5 percent of organic resin, 1 to 5 percent of inorganic matter,and 1 to 3 percent of flatting agent. According to the anticorrosive paint, the preparation method, and the application of the anticorrosive paint in the air conditioner fan metal wet curtain providedby the invention, through adding the rare earth compound, the occurrence of corrosion reaction is inhibited, so that an anti-corrosion effect is greatly improved; meanwhile, through adding the organic resin into an inorganic binder formed by the rare earth compound and the oxysalt, a binding force and anti-corrosion performance of a coating on a metal surface are improved; in addition, through adding the flatting agent, a smooth anticorrosive coating film can be formed on an anticorrosive surface of metal, and the smooth anticorrosive coating film and an inorganic hydrophilic film coating a surface layer thereof form a favorable binding effect, so that the anticorrosive paint has favorable water resistance and excellent acidic-basic material corrosion resistance when being applied in theair conditioner fan metal wet curtain.

Description

technical field [0001] The invention relates to the technical field of metal anticorrosion treatment, in particular to an anticorrosion coating, a preparation method and its application in metal wet curtains of air-conditioning fans. Background technique [0002] The development of human culture is the development process of materials. The appearance of metal materials has significantly promoted the progress of human material civilization. However, the corrosion problem of the surface of metal materials widely used in human life has also caused huge losses to human society. Corrosion can deteriorate the performance of the parts, reduce the precision, make the surface uneven, shorten the service life, and even scrap them. According to statistics, in industrialized countries, the annual cost of repairing or replacing products due to corrosion accounts for about 5% of national income. Therefore, the anti-corrosion treatment of metal is of great significance. [0003] Among th...
