Problems solved by technology

[0002] Anti-corrosion and wear-resistant coatings are an indispensable coating in paints and coatings. The annual economic losses caused by corrosion in the world are about 1 trillion US dollars, which is the sum of the losses caused by earthquakes, fires, and wind disasters. Anti-corrosion and wear-resistant coatings are the most effective. , the most economical and most commonly used anti-corrosion method has received widespread attention at home and abroad. Under normal conditions, anti-corrosion and wear-resistant coatings can prevent corrosion of metals and prolong the service life of non-ferrous metals. The anti-corrosion function lies in the coating The shielding effect, resistance effect, wet adhesion, chemical passivation and cathodic protection. Although many kinds of anti-corrosion and wear-resistant coatings have been developed at home and abroad, they still cannot meet the needs. How to prepare a kind of anti-corrosion coating with excellent anti-corrosion performance and small friction loss , the coating with long service life has become a technical problem that needs to be solved at present
