Sublimation printing stainless steel and preparation method thereof

Abstract

The invention discloses sublimation printing stainless steel and a preparation method thereof. The sublimation printing stainless steel comprises a stainless steel body. The front face and the back face of the stainless steel body are each coated with a dewatering resin coating layer, the outer surface of each dewatering resin coating layer is covered with a layer of printed transfer printing film, the surface of each transfer printing film is coated with a hydrophilic material layer, and the surface of each hydrophilic material layer is printed with a layer of heat transfer printing ink. The heat transfer printing ink comprises, by weight, 25-45 parts of disperse dyes, 8-17 parts of carboxymethylcellulose, 3-12 parts of viscosity modifier, 3-8 parts of a surface active agent, 4-12 parts of sodium lignin sulfonate, 3-7 parts of inorganic oxide, 2-6 parts of preservative, 5-15 parts of corrosion inhibitor, 3-13 parts of styrene acrylic resin and 3-12 parts of polyvinyl alcohol. The preparation method is simple, a printed pattern on the prepared stainless steel is high in definition and not prone to falling off and improves the ornamental value of the stainless steel, and the degree of adhesion is achieved.

Description

technical field [0001] The invention relates to the technical field of printing stainless steel preparation, in particular to a sublimation printing stainless steel and a preparation method thereof. Background technique [0002] At present, both at home and abroad, most of the stainless steel surface printing technology adopts screen printing overlay technology. Because this kind of technology can only be screen printed after processing and forming, and requires overlay and printing, the process is very complicated. Some coconut oil uses continuous inkjet on the surface. , or the pattern is cold-rolled on the stainless steel surface, and the use of ink spraying will cause volatilization and pollution during the processing process. At the same time, the printing pattern is not clear, and the stainless steel surface will be worn during the processing process, affecting its aesthetics. Contents of the invention [0003] The purpose of the present invention is to provide a sub...

[0002] At present, both at home and abroad, most of the stainless steel surface printing technology adopts screen printing overlay technology. Because this kind of technology can only be screen printed after processing and forming, and requires overlay and printing, the process is very complicated. Some coconut oil uses continuous inkjet on the surface. , or cold-roll the pattern on the surface of stainless steel. When spraying ink, it will volatilize and easily cause pollution during the process. At the same time, the printed pattern is not clear, and the stainless steel surface will be worn during the process, which will affect its aesthetics.
