preparation example Construction

[0049] The preparation method of anti-corrosion anti-fingerprint surface treatment agent, it comprises the following steps:

[0050] Under the condition of stirring, the surface treatment agent is prepared according to the above-mentioned weight percentage ratio; grinding; the solid content of the mixed treatment agent is adjusted to 10-50%, and the viscosity is 10-50CPS; the material is packed.

[0051] The nano-oxide is added in the form of nano-oxide concentrated slurry during the preparation of the surface treatment agent.

[0052] The nano-oxide concentrated slurry is composed of 30-65% of nano-oxide, 10-50% of silane mixture and the rest of water.

[0053] First add the pH adjuster to the water, then slowly add the mixture of silane and nano-oxide to make a concentrated slurry of nano-oxide, and then add the metal compound to the mixed slurry of organic polymer resin, silicone resin, and water-based wax according to the proportion , after stirring and mixing evenly, the...

Abstract

The invention discloses a corrosion and fingerprint resistant surface treatment agent and a preparation method thereof as well as a use method on stainless steel plates. The weight percentages of the chemical ingredients are as follows: 7-45% of organic macromolecule resin, 2-15% of organic silicon resin solution, 0.5-10% of water system wax, 0.5-10% of nano-oxide, 0.1-20% of metallic compound, 0.1-15% of silane mixture and water being the rest. The preparation method comprises: a pH regulator is added into water, and then the silane mixture and nano oxide are slowly added to prepare nano oxide concentrate; the concentrate is mixed and stirred with the ingredients to form film and is mixed into a treatment agent. The use method of the treatment agent on the stainless steel plates comprises washing, coating and drying. Compared with the prior art, the coating of the invention has good adhesion and ductibility on the surface of the stainless steel and is free from flaking off, thereby enhancing the production efficiency. Coatings resisting corrosion, fingerprint and scratch and stainless steel plates can be obtained.

Description

technical field [0001] The invention relates to a corrosion-resistant and fingerprint-resistant stainless steel plate, in particular to a corrosion-resistant and fingerprint-resistant surface treatment agent and a method for preparing and using the same on the stainless steel plate. Background technique [0002] Anti-fingerprint processing itself is a relatively mature technology with a certain development history. The research and production of electro-galvanized fingerprint-resistant panels originated in Japan and entered commercial production in the early 1980s. By the 1990s, Baosteel, Taiwan China Steel, South Korea's Posco and other steel mills also produced electro-galvanized anti-fingerprint steel plates one after another. The traditional production process of anti-fingerprint steel plate: carbon steel cold-rolled plate → electro-galvanizing → phosphating → chromium or chromium-free passivation → resin coating → drying → cooling. The original purpose of anti-fingerp...
