Abstract

The invention relates to a reutilization material for a silk screen board and a reutilization method of the reutilization material. The material comprises sensitive glue and demolding powder, the sensitive glue comprises, by weight, 100 parts of second alcohol soluble or nylon terpolymer, 20-35 parts of acrylic amide and bisacrylamide monomers, 2.6-4.8 parts of benzophenone and 0.08-0.23 parts of heat stabilizer, and the weight ratio of the acrylic amide to the bisacrylamide is 1: (1-2). The demolding powder comprises, by weight, 50-60 parts of sodium metaperiodate, 5-10 parts of surface active agents, 1-3 parts of chelating agents, 6-10 parts of peroxide and 3-5 parts of inorganic salt. Characteristics of thick molding printing screen are considered on the whole, clearly printing and completely demolding are achieved by the aid of sensitive glue, demolding powder and demolding process of mutual coordination effects, silk screen tension of the silk screen board is larger than or equal to 20N / CM based on completely demolding, normal circulation use requirements are met, the silk screen board can be reutilized by 7-8 times, and printing cost is effectively reduced.

Description

technical field [0001] The invention relates to a material for reusing screen printing screen plates and a reusing method thereof, belonging to the technical field of screen printing. Background technique [0002] The method of direct plate making in the automotive industry is to first put the photosensitive film coated with photosensitive material face up on the working table, put the stretched screen frame flat on the film base, and then put it in the screen frame. The photosensitive paste is coated under pressure with a soft scraper, and the plastic film base is removed after it is fully dried, and the photosensitive film wrist screen is attached to the printing plate, and the screen printing screen is produced after developing and drying. Most of the screen frames are made of aluminum alloy screen frames. Since the pre-applied glue on the surface of the gasket plays a role in strengthening the seal, thick film printing is used. The special photosensitive glue on the surf...
