Embodiment 1

[0027] First, prepare the screen printing protection ink composition in the present invention: first prepare the acid-resistant ink and the amine curing agent in proportion and stir evenly, then add superfine Stir the rubber powder and diluent (ketone solvent) evenly; the weight ratio is ink:curing agent:diluent:rubber powder=100:1:8:10. Among them, the acid-resistant ink is the acid-resistant ink of the model IP-505-03 produced by Matsui Chemical, the ultra-fine rubber powder is the ultra-fine rubber powder produced by Mingjintai Rubber and Plastic Products Company, and the curing agent is the model DA-043 produced by Matsui Chemical The amine solidifying agent, the diluent is the ketone-containing solvent of the model KJ001 that Matsui Chemical produces.

[0028] Preparation: Prepare the screen version (screen version of about 120T mesh), screen printing machine and such as figure 1 The shapes and dimensions shown in are all processed white glass.

Embodiment 2

[0033] The weight ratio of the screen printing protective ink composition in this embodiment is ink:curing agent:diluent:rubber powder=100:0.8:8:8, and the rest of the conditions are the same as in Example 1. The obtained screen printing protective ink composition can play an ideal protective effect when used for screen printing.

Embodiment 3

[0035] The weight ratio of the screen printing protective ink composition in this embodiment is ink:curing agent:diluent:rubber powder=100:1.2:10:15, and the rest of the conditions are the same as in Example 1. The obtained screen printing protective ink composition can play an ideal protective effect when used for screen printing.

Abstract

The invention provides a screen printing protective ink composition. The ink composition comprises acid-resistant ink and ultrafine rubber powder, wherein the average particle diameter of the ultrafine rubber powder is less than or equal to 0.04mm and the mass of the ultrafine rubber powder accounts for 5-20% of mass of the acid-resistant ink. The invention also correspondingly provides a screen printing method. According to the technical scheme, a product of which a specific position on the surface of glass has a frosting effect is produced, the blocking of a fixture is not needed in the blasting process, the ink at a non-frosting region can resist blast and strike and meanwhile, after the etching process is completed and the plating layer is removed, the condition of poor appearance caused by corrosion on the surface of glass at the non-frosting region is caused.

Description

technical field [0001] The invention relates to a screen printing protection ink composition and a screen printing method. Background technique [0002] The frosting effect on the glass surface is popular in the market because of its fog and hand feeling. More and more industries are developing sandblasting and etching processes for preparing the frosting effect on the glass surface. To obtain the effect of frosting on the glass surface, in this field, the frosting area on the glass surface is generally determined first, and then the non-frosting area on the glass surface is covered with silk screen printing ink by accurately positioned silk screen; and then the entire surface of the glass surface is covered. Sandblasting and etching, the area covered with screen printing protection ink will not be affected by the impact and corrosion of sandblasting and etching steps; after that, the covered screen printing protection ink is deplated and cleaned, thus obtaining a frosting e...
