Zinc metallic coating

Abstract

The invention discloses a zinc metal coating layer, the zinc metal coating is characterized in that when being calculated according to the parts by weight, the components of the the zinc metal coating are as follows: 50 parts to 100 parts of polyether silicate ester or polymerized silica acid ester, 50 parts to 100 parts of polyvinyl butyral or ethyl cellulose, 1 part to 20parts of one or a plurality of component (s) among nanometer silicon dioxide, nanometer titanium dioxide, nanometer molybdenum dioxide, or nanometer zinc oxide, 80 parts to 200 parts of zinc powder, 0 to 20 parts of rust preventing agent,, 5 parts to 100 parts of coupling agent, 5 parts to 25 parts of brightening agent, 8 parts to 250 parts of film forming auxiliary agent, 5 parts to 10 parts of wettinh agent, 1 part to 5 parts of surface activating agent, 100 parts to 200 parts of thinning agent, 0.5 part to 3 parts of anti-foaming agent and 0.5 part to 5 parts of anti-scratching agent. The bright metal zinc coating layer related by the invention can be taken as the anti-corrosive oxidation resistant zinc metal coating layer of metal product, particularly the black metal product, which can replace the commonly adopted galvanizing technology. The bright zinc metal coating layer of the invention can very conveniently and effectively paint a zinc metal coating layer the binding of which is firm on the metal product, particularly the black metal product.

Description

technical field [0001] The present invention relates to a zinc metal coating. Background technique [0002] People usually plate a layer of other metals or alloys on the surface of metal or ferrous metal products, such as: metal zinc, nickel, chromium, copper, rhodium, etc., to achieve or improve the corrosion resistance and other properties of the base metal. In industry, the most widely used production process is the electroplating process, but the traditional electroplating process uses a variety of toxic and harmful substances, such as: various inorganic, organic acids, cyanides, chromates and other chemicals; thus , will cause serious safety and environmental problems. In addition, the process of the traditional electroplating process is very complicated. Before electroplating, a series of process treatments must be performed on the surface of the metal parts, such as: roughening, activation, sensitization or other corresponding metal transition layers need to be pre-p...

Problems solved by technology

In industry, the most widely used production process is the electroplating process, but the traditional electroplating process uses a variety of toxic and harmful substances, such as: various inorganic, organic acids, cyanides, chromates and other chemicals; thus , will cause serious safety and environmental problems

In addition, the process of the traditional electroplating process is very complicated. Before electroplating, a series of process treatments must be performed on the surface of the metal parts, such as: roughening, activation, sensitization or other corresponding metal transition layers need to be pre-plated; After electroplating, it must be processed by hydrogen removal, passivation, drying and other processes; in short, in addition to solving environmental protection problems, the traditional electroplating process also urgently needs to consider and solve how to reduce the labor intensity of operators and safety production issues; of course, other High process cost also needs to be solved
