Problems solved by technology

As we all know, one of the disadvantages of sheet metal is that it is easy to be corroded, especially when stored and used under high temperature and humid conditions, not only the appearance is obviously damaged, but also the mechanical quality is also significantly reduced, which affects the quality of use. There are countless originals or products, so they need to be protected
Coating is a common substance to protect metal plates from corrosion. The raw material composition of existing coatings is not well prepared, resulting in poor protection effect and durability, which needs continuous improvement.

Abstract

The invention discloses anticorrosion paint for metal plates. The anticorrosion paint is prepared from epoxy resin, C9 petroleum resin, urea formaldehyde resin, polyurethane, styrene-acrylic emulsion,n-butyl alcohol, an antifoaming agent, a thickening agent, a silane coupling agent, a wetting agent, an ultraviolet absorbing agent and modified reinforcing filler. By improvement and modification ofthe anticorrosion paint, the protection performance and utilization effects of the paint are evidently improved, corrosion resistance of the metal plates can be remarkably improved, service lives ofthe metal plates are prolonged, and the anticorrosion paint is extremely high in market competitiveness and popularization and utilization values.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-corrosion coating for metal plates. Background technique [0002] Metal sheet, as the name implies, is a sheet made of metal processing, such as iron sheet, aluminum sheet, stainless steel sheet, copper sheet and so on. Sheet metal is an indispensable raw material for modern machinery, construction, shipbuilding and other industries. The characteristics of the sheet itself are closely related to the performance of the product or processing. As we all know, one of the disadvantages of sheet metal is that it is easy to be corroded, especially when stored and used under high temperature and humid conditions, not only the appearance is obviously damaged, but also the mechanical quality is also significantly reduced, which affects the quality of use. There are countless originals or products, so they need to be protected. Coating is a common material for protecting metal plates from corrosion. T...
