Abstract

The invention discloses a preparation method of an environmental-friendly nano-filming agent. The environmental-friendly nano-filming agent is prepared from the following raw materials in percentage by mass: 3 percent to 9 percent of fluorozirconic acid, 1 percent to 6 percent of a coupling agent, 0.5 percent to 1.2 percent of zirconium oxychloride, 0.4 percent to 2 percent of citric acid and the other being 50 percent to 80 percent of water. The compound silane coupling agent is obtained by compounding two silane coupling agents, the consumption of the silane coupling agent A is 1 percent to 6 percent, the consumption of the silane coupling agent B is 0.3 percent to 0.6 percent, the silane coupling agent A is 3-aminopropyltriethoxysilane, and the silane coupling agent B is gamma-glycidoxy propyl trimethoxy silane. According to the preparation method of the environmental-friendly nano-filming agent disclosed by the invention, through a spraying or soaking way, a layer of colorless anti-corrosion passivating layer is formed on the surface of iron and aluminum, so that the adhesive force and the corrosion resistance of coatings and a substrate can be improved, and the method has a good environmental protection effect.

Description

technical field [0001] The invention relates to the technical field of nano-coating agents, in particular to a preparation method of an environment-friendly nano-coating agent. Background technique [0002] On the basis of the successful development and production of non-phosphorus degreasing agent, we also borrowed and introduced the technology of non-phosphorus coating film from abroad, and produced a non-phosphorus coating film agent in China to replace the phosphating solution, and successfully realized the whole line of China's coating pretreatment process No phosphating, fundamentally eliminates the problem of phosphorus pollution in the pretreatment process. Phosphorus-free degreasing agent and non-phosphorus film liquid developed and produced by Surface Technology Research Institute fundamentally eliminate phosphorus pollution and meet the urgent needs of environmental protection. The treatment effect is also very outstanding. The treatment effect of phosphorus degr...
