Anti-corrosive paint

Abstract

The invention discloses anti-corrosive paint and belongs to the field of fine chemical engineering. The paint is prepared from raw materials in parts by weight as follows: 1.2-2.4 parts of feldspar powder, 0.8-1.6 parts of tribenzyl phenol polyoxyethylene ether, 1.4-2.9 parts of zinc phosphate, 2.6-4.7 parts of polysiloxane, 6-12 parts of epoxy grafted aacrylic resin, 1.8-3.9 parts of polyether sulfone, 1.6-3.2 parts of sodium thiocyanate and 1.2-2.9 parts of sodium diisopropyl naphthalene sulphonate. Compared with existing anti-corrosive paint, the paint has the advantages of corrosion resistance, aging resistance, high / low-temperature resistance, good ductility and high elongation at break, is suitable to be applied to surfaces of multiple base materials, has good friction resistance and has excellent storage stability.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an anticorrosion coating. Background technique [0002] The material is in the external environment, and the material deterioration and destruction caused by the reaction with the corrosive medium occur every moment, causing huge losses to human beings. The metal materials scrapped due to metal corrosion account for 20-40% of the annual metal production in the world, resulting in a great waste of natural resources. According to the authoritative data analysis of the National Association of Anti-Corrosion Engineering (NACE), the United States is caused by rotten candles every year. In my country, the direct and indirect economic losses caused by metal corrosion are about 500-600 billion yuan, accounting for 5% of GDP. %, so finding a suitable method to prevent material corrosion is of great significance to the energy saving, environmental protection and sustainable development of the ...

Problems solved by technology

[0004] At present, traditional coatings are generally used for corrosion protection of metal materials. Most of the coatings are limited to anti-corrosion features. Their water resistance and storage stability are poor, and flash rust occurs. At the same time, pigments and fillers often flocculate during storage. Problems that seriously affect the performance of anti-corrosion coatings
