Problems solved by technology

The difference is: "Dacromet" coating is a mixed solution composed of flaky zinc, aluminum powder, anhydrous chromic acid, reducing agent, dispersant, control agent, and distilled water. The metal surface is then roasted and dried at 300°C to form a layer of coating. So far, this technology is only suitable for metal substrate anti-corrosion. Because this technology is a US patent and is used in my country, the cost is relatively high.

Abstract

An environmental-protection type nano-class liquid aluminium foil as a chemicoplating material on the surface of metal is prepared from pure coster oil, TDI, epoxy resin, aluminium powder and nano-class filler through a special process. It has solvent type and water type. Its advantages are low cost, excellent anticorrosion performance, and no environmental pollution.

Description

1. Technical field [0001] The nano-environmentally friendly liquid aluminum foil of the invention and its preparation method and use method belong to the technical field of nano-scale chemical coating or electroless plating. 2. Background technology [0002] Galvanizing is the main means of surface protection of steel products. The traditional galvanizing process is divided into hot-dip galvanizing and electro-galvanizing. During the process, as well as before and after galvanizing, pollution will be produced to varying degrees. However, due to the good anti-corrosion performance of galvanized steel products, it protects machinery, buildings and some special facilities. It has become an indispensable part of human civilization and is still widely used. However, with the development of science and technology and the needs of human survival, the traditional electro-galvanized coating can no longer meet the needs, especially the environmental requirements. It is urgent to inve...
