Silk screen printing ink for metal

Abstract

The invention relates to silk screen printing ink for metal, which comprises the following components in parts by mass: 25-30 parts of colloidal calcium carbonate, 10-20 parts of ethylene glycol butyl ether, 15-30 parts of china clay, 35-40 parts of titanium dioxide, 50-60 parts of linseed alkyd resin, 10-15 parts of precipitated barium sulphate, 15-20 parts of butylated melamine resin, 15-20 parts of paraffin, 15-20 parts of painter naphtha, 30-40 parts of dehydrated castor alkyd resin and 1-2 parts of n-butyl alcohol. The silk screen printing ink for the metal is high in production efficiency, low in energy consumption, and good in surface hardness, friction resistance and light resistance, and the labor intensity of a worker is reduced greatly.

Description

technical field [0001] The invention relates to an ink, in particular to a screen ink for metal. Background technique [0002] Screen printing ink, also known as screen printing ink, usually refers to the ink used in screen printing. It is widely used, including fabric printing, plastic printing, metal printing, ceramic printing, glass printing, electronic product printing, lottery screen printing And so on. [0003] The range of metal screen printing is very wide, and it can print all kinds of logo roots, panels, signs and metal moldings. Most of them are decorated by direct printing, and there is not much difference in silk screen printing skills, but metal products are durable goods, and the surface decoration requirements are higher and more durable. Therefore, surface treatment is often carried out before printing, such as surface coating, electroplating, and anodizing. Oxidation or mechanical roughening (travel pattern, wire drawing), etc. When printing, it is neces...
