Abstract

The invention relates to a high-efficiency depainting film for metal materials, which comprises 26-69 wt% of Ni, 15-35 wt% of Si, 5-15 wt% of polyurethane resin and 25-49 wt% of hydroxymethylated phenol. The depainting film is 5-50 mu m thick. The high-efficiency depainting film for metal materials has the advantages of low toxicity, low volatility, high depainting capacity, wide application range, low raw material cost and the like.

Description

technical field [0001] The invention relates to a metal treatment agent, in particular to a high-efficiency paint stripping film for metal materials. Background technique [0002] The recycling of scrap metal is of great significance to alleviate the increasingly prominent contradiction of the relative shortage of resources in our country, and to realize the optimal allocation of resources and sustainable development. However, many recycled scrap metal surfaces are coated with a protective paint. In order to obtain relatively pure metal materials, the protective paint attached to the surface must be removed. Therefore, a high-efficiency paint stripper for metal materials is proposed. Therefore, providing a high-efficiency paint stripping film for metal materials has become an urgent problem to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0003] In view of the above problems, the main purpose of the present invention is to provide a high-efficiency pai...
