Embodiment 1

[0041] Epoxy resin / curing agent diluted with 30 parts DPGDA per 100 parts epoxy resin 125g

[0042] Modified SBQ resin aqueous solution: (13%) 210g

[0043] ITX 2.5g

[0044] Additive 15g

[0045] water 220g

[0046] The emulsion prepared by the above formula is poured on a nickel mesh. After drying with hot air at 40°C, the pattern is exposed. Soak in water at 20°C, and the flower shape will appear after entering the water. Rinse the screen with tap water after 2 minutes, and the image reproducibility is good. After the pattern screen was cured at a high temperature of 165°C for 2 hours, 30,000 meters of fabric could be printed without damage to the pattern.

Embodiment 2

[0048] Epoxy resin / curing agent diluted with 35 parts phenoxydiethylene glycol diacrylate per 100 parts epoxy resin 160g

[0049] Modified SBQ resin aqueous solution (13%) 200g

[0050] Benzoin methyl ether 3g

[0051] Additive 15g

[0052] water 200g

[0053] Prepare an aqueous emulsion with the above formula and pour it on a nickel mesh. After drying with hot air at 40°C, the pattern is exposed. Immersed in water at 30°C, the flower shape will appear. Rinse with tap water after 1.5 minutes to reveal a flower pattern. Image reproducibility is good. After the pattern screen was cured at 180°C for 1.5 hours, 30,000 meters of fabric could be printed without damage to the pattern.

Embodiment 3

[0055] Epoxy resin / curing agent diluted with 15g hydroxyethyl acrylate and 20g EO-TMPTA per 100 parts epoxy resin 60g

[0056] Modified SBQ resin aqueous solution (13%) 63g

[0057] Benzophenone 5g

[0058] Additive 10g

[0059] water 477g

[0060] Prepare an aqueous emulsion with the above formula and pour it on a nickel mesh. After drying with hot air at 40°C, the pattern is exposed. Soak in water at 35°C, see flower shape in water. Rinse with tap water after 1.5 minutes to reveal a flower pattern. The image is clear. After the screen was cured at 170°C for 2 hours, 30,000 meters of fabric could be printed without damage to the pattern.

Abstract

The invention discloses an environment-friendly aqueous emulsion type cylinder photoresist, which comprises modified SBQ resin aqueous solution, epoxide resin diluted by hydrophilic unsaturated monomer, epoxide resin curing agent and light polymerization initiator.

Description

technical field [0001] The present invention relates to water-emulsion type cylinder photosensitive glue, especially the water-emulsion type cylinder photosensitive glue made of hydrophilic unsaturated monomer with ethylenic group instead of dichromate as photosensitizer. . Background technique [0002] The current water-emulsion type rotary screen photosensitive adhesive on the market is mainly composed of dichromate / PVA to form a photosensitive system; epoxy resin is used to form an adhesive system. Because of its relatively cheap price, good photosensitive performance, convenient net making, and good printing fastness. It has dominated the rotary screen printing market at home and abroad for a long time. [0003] For the above-mentioned water-emulsion type rotary screen photosensitive adhesive, the photosensitizer dichromate aqueous solution is mixed into the photosensitive adhesive before use, and an adhesive layer of a certain thickness is coated on the rotary screen....
