Abstract

The invention provides a surface coating composition and a preparation method thereof; the components of the composition comprises polyvinyl butyral, alcohol, methyl substituted benzene, rosin, zinc phosphate, oxalic acid and fluorine-silicon polymers; the alcohol is alcohol having 2-4 C; the weight ratio of the components is 1:5-8:2-4:0.5-1.5:0.5-1:0.05-0.1:0.5-1.5; the method comprises: mixing,emulsifying and grinding the polyvinyl butyral, alcohol, methyl substituted benzene, rosin, zinc phosphate, oxalic acid and fluorine-silicon polymers; the surface coating composition can be applied to surface of metal members such as iron tower and other electricity equipment as permanent corrosion resistant coating material.

Description

technical field [0001] The invention provides a composition, especially a surface coating composition, which belongs to a fluorosilicon anticorrosion coating. Background technique [0002] As a main channel of energy transportation, the power system has played a huge role in the development of the national economy. Metal materials are an important structural material of power transmission and transformation equipment in power systems, including towers of overhead power transmission lines, bases of power transmission and transformation equipment, cabinets, etc. are all metal components mainly made of steel. However, a large number of line towers and other metal components have been operating in various harsh environments for a long time, including chemical plants, chemical fertilizer plants, pharmaceutical factories, mines and other heavily polluted environments. Under long-term operating conditions, corrosion often occurs on the surface of metal components. According to inc...
