Problems solved by technology

[0004] But the above-mentioned water-emulsion type rotary screen photosensitive adhesive, the adhesive layer after hot air baking is in a high-temperature and high-humidity environment (such as Huangmeitian), and its surface is sticky (hereinafter referred to as "sticking phenomenon") to hinder the movement of the film sheet, and the image is drawn correctly. It is difficult to form, and even affect the flower-shaped net cylinder with high-definition patterns

Embodiment 1

[0015] 100g of tung oil anhydride, 17g of 4.4' diaminodiphenyl sulfone, heated to 50-85°C under stirring, and kept for 1.5 hours. Use this as epoxy resin curing agent to prepare water-emulsion type garden net photosensitive adhesive, and pour it on the garden net nickel net. Dry at 40°C with hot air, test with a film sheet in an environment with a relative humidity of ≥95% at 40°C, it is non-sticky, smooth, and can be pushed freely. After the flower-shaped net cylinder was cured at 170°C for 2.5 hours, the printed fabric was 30,000 meters, and the pattern was complete without damage.

Embodiment 2

[0017] Tung oil anhydride 100g, 4.4' diaminodiphenyl sulfone 23g, heat to 45-85°C under stirring, keep warm for 2 hours, use this as epoxy resin curing agent, make water-emulsion type garden net photosensitive glue, cast on the garden net Nickel mesh. Dry at 40°C with hot air, test with a film sheet in an environment with a relative humidity of ≥95% at 40°C, it is non-sticky, smooth, and can be pushed freely. After the flower-shaped net cylinder was cured at 165°C for 1.5 hours, the printed fabric was 30,000 meters, and the pattern was complete without damage.

Embodiment 3

[0019] Tung oil anhydride 100g, 4.4' diaminodiphenyl sulfone 14g, heat to 50-90°C under stirring, keep warm for 2 hours, use this as epoxy resin curing agent to prepare water-emulsion type photosensitive adhesive for garden net, pour it on the garden net Nickel mesh. Dry with hot air at 40°C, in an environment with a relative humidity of ≥95% at 40°C, test with a film sheet, it is non-stick, smooth, and can be pushed freely. After the flower-shaped net cylinder was cured at 180°C for 2 hours, the printed fabric was 30,000 meters, and the pattern was complete without damage.

Abstract

The present invention discloses an eleostearic acid anhydride / 4,4'-diaminodiphenylsulfone addition product, also discloses its production method and also discloses its application. Said addition product can be used as epoxy resni solidifying agent, can be used in water-emulsion type cylinder mould photosensitive resists.

Description

technical field [0001] The present invention relates to a curing agent for epoxy resin for coatings, in particular to an effective curing agent for epoxy resin in water-emulsion type cylinder photosensitive glue. Background technique [0002] Water-emulsion type rotary screen plate-making photosensitive glue is composed of two parts: photosensitive system and adhesion system. The photosensitive system is dichromate / polyvinyl alcohol; the adhesion system is epoxy resin with excellent adhesion to metal nickel mesh, good corrosion resistance to chemicals and outstanding wear resistance, and its matching curing The agent is tung oil anhydride. The thus prepared circular mesh flower-shaped net tube (ie, the stencil) can run at a high speed for a long time and withstand the extrusion of a scraper (or magnetic bar) after being cured at a high temperature. It meets the requirements of various fabric printing techniques and technology development, and is very popular. [0003] The...
