Abstract
The utility model relates to a color coating structure on the steel workpiece surface without applying middle coating, which is characterized in that at least three layers of film are arranged on the steel workpiece surface; wherein, a first layer is a phosphate conversion film; a second layer is an electrophoretic paint film; a fourth layer is a transparent finishing paint layer. The utility model is characterized in that a third layer is a metallic flashing fundamental color paint or true and fundamental color paint layer. The utility model has the advantages of reducing color coating application cost on the steel workpiece, saving energy and meeting the higher requirements of environmental protection regulations with excellent performance.
Description
Technical field
The utility model belongs to surface of the work and decorates and the guard technology field structure of the coloured coating of coating during particularly a kind of surface of steel workpiece is exempted from.
Background technology
At present, both at home and abroad iron and steel parts enamel coating traditional application techniques maturation, be widely used, technology is relatively stable.Traditional coloured coating is made up of phosphate conversion film and multilayer nonmetallic materials.Coating structure is: ground floor is the phosphate conversion film; The second layer is an electrophoretic paint layer; The 3rd layer is floating coat; The 4th layer is flash metal luster primary colours enamelled coating or true qualities primary colours enamelled coating or true qualities top coat layer; Layer 5 is transparent Lacquer finish enamelled coating.Because new application techniques is in order to pursue the reduction painting cost, energy-conservation and the satisfied environmental requirement of raising day by day, consideration has breakthrough on the coloured coating structure of iron and steel parts.
Summary of the invention
The purpose of this utility model be exactly deficiency at traditional iron and steel parts coloured coating provide a kind of surface of steel workpiece exempt from the coloured coating structure of coating.
The technical solution of the utility model is achieved in that
The coloured coating structure of coating during surface of steel workpiece is exempted from, at surface of steel workpiece film more than three layers or three layers is arranged, first tunic is that phosphate conversion film, second tunic are electrophoretic paint layer, the 4th tunic is transparent Lacquer finish enamelled coating, it is characterized in that: trilamellar membrane can be flash metal luster primary colours lacquer or true qualities primary colours enamelled coating or true qualities top coat layer.
The utility model has solved the difficult problem of the painting cost that reduces the coloured coating on the existing iron and steel parts, saves the energy, adapts to the requirement and the function admirable of the environmental regulation of higher degree.
