Wear-resistant and scratch-resistant coating and preparation method thereof

Abstract

The invention discloses a wear-resistant and scratch-resistant coating and a preparation method thereof, and belongs to the technical field of wear-resistant coatings. According to the wear-resistantand scratch-resistant coating and the preparation method thereof, the wear-resistant and scratch-resistant coating is formed by uniformly coating a wear-resistant and scratch-resistant coating on a composite film and curing the wear-resistant and scratch-resistant coating, the wear-resistant and scratch-resistant coating is prepared from the following components: polyvinyl acetal modified phenolicresin, polyacrylic acid vinyl ester emulsion, composite rare earth, nano aluminum powder, nano calcium oxide, ceramic powder, a flame retardant and the like. The wear-resistant and scratch-resistantcoating disclosed by the invention has excellent bonding strength; the wear-resistant and scratch-resistant coating has the advantages of favorable dielectric properties, favorable product dimensionalstability, high hardness, favorable flexibility, high stability for alkali and most solvents, favorable corrosion resistance, favorable gas resistance, favorable water resistance, favorable flame retardancy and the like, and has long service life, and the wear-resistant and scratch-resistant coating obtained by coating the wear-resistant and scratch-resistant coating can not have the problems ofblistering, cracking, whitening, delaminating and the like. The preparation method is simple, and large-batch and large-scale production is easy to carry out.

Description

technical field [0001] The invention relates to the technical field of wear-resistant coatings, in particular to a wear-resistant and anti-scratch coating and a preparation method thereof. Background technique [0002] Anti-corrosion and wear-resistant coatings are coatings used to protect substrates or objects to be protected, and most of them are obtained by curing after coating. Coating is an indispensable coating in paints and coatings. The annual economic loss caused by corrosion in the world is about 1 trillion US dollars, which is the sum of the losses caused by earthquakes, fires and wind disasters. Coating anti-corrosion and wear-resistant coatings is the most effective and economical. , The 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...

Coating is an indispensable coating in paints and coatings. The annual economic loss caused by corrosion in the world is about 1 trillion US dollars, which is the sum of the losses caused by earthquakes, fires and wind disasters. Coating anti-corrosion and wear-resistant coatings is the most effective and economical. , The 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 shielding effect of the coating , 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 coating with excellent anti-corrosion performance, small friction loss and long service life? Long paint has become a technical problem that needs to be solved at present
