Problems solved by technology

However, because this treatment method contains harmful heavy metal ions such as zinc and nickel and chemical components such as phosphorus, and will produce a large amount of phosphating slag during the treatment process, it will cause great harm to the environment. Furthermore, the phosphating treatment technology consumes The performance is large, and the degree of dependence on the previous surface adjustment process is large, which also increases the processing cost and management difficulty

Abstract

The invention discloses a special ceramic membrane treating agent for an environment-friendly non-phosphorus electrophoresis. The treating agent comprises zirconium fluoride and / or fluotitanic acid, water-base resin, silane and disperse nano particles. Each kilogram of treating agent comprises, by mass, 30-50 g of zirconium fluoride acid or fluotitanic acid, 80-120 g of water-base resin, 30-50 g of amino silane or epoxy silane, 1-10 g of disperse nano particles, and the balance water. The invention further provides a preparation method of the special ceramic membrane treating agent for the environment-friendly non-phosphorus electrophoresis, and further provides a method for forming a membrane through treatment of the special ceramic membrane treating agent for the environment-friendly non-phosphorus electrophoresis. The membrane formed by the treating agent and the electrophoresis form a metal layer, the metal layer is high in combination degree, and the physical combination capacityof a ceramic body and an electrophoresis coating can be effectively improved.

Description

technical field [0001] The invention specifically relates to an environment-friendly and non-phosphorus electrophoresis special ceramic membrane treatment agent. The invention also relates to a preparation method of the above-mentioned environment-friendly and non-phosphorus electrophoresis special ceramic membrane treatment agent. The present invention also relates to a method for forming a film layer by using the above-mentioned environment-friendly non-phosphorus electrophoresis special ceramic film layer treatment agent. Background technique [0002] Phosphating treatment is mostly used in the metal surface treatment technology before traditional electrophoretic coating. However, because this treatment method contains harmful heavy metal ions such as zinc and nickel and chemical components such as phosphorus, and will produce a large amount of phosphating slag during the treatment process, it will cause great harm to the environment. Furthermore, the phosphating treatme...
