Problems solved by technology

The application of DMD lithography technology is a great progress in the field of screen making technology, but it also puts forward high requirements on the resolution performance and exposure rate of photosensitive adhesives. Currently, commercially available photosensitive adhesives are not only polluted by heavy metals such as hexavalent chromium The problem is that the resolution accuracy and exposure rate are far from meeting the requirements of DMD lithography technology, and there is no way to maximize the advantages of DMD lithography technology
Equally, also do not see the relevant high-sensitivity photoresist patent disclosure that can be used for DMD lithography technology

Abstract

The invention relates to a new environment-friendly photosensitive polymer material, in particular to a high-sensitivity environment-friendly single-component rotary mesh photosensitive adhesive and a preparation method and application thereof. The high-sensitivity and environment-friendly one-component rotary network photosensitive adhesive of the present invention is mainly composed of a thermosetting resin, a latent curing agent, a toughening resin, a photocurable resin, a photopolymerization initiator, a sensitizer, a free radical scavenger and an additive. The self-emulsifying process is used to make high-sensitivity and environmental-friendly one-component rotary screen photosensitive adhesive. Due to the efficient sensitization reaction of the photosensitive system, a high-sensitivity photosensitive speed and an ultra-high resolution of 20um are obtained; the environmentally friendly one-component rotary screen photosensitive adhesive made from this can be stored stably for a long time, not only can replace the traditional Bichromate / PVA and other two-component photosensitive systems solve the problem of hexavalent chromium heavy metal pollution in the prior art, and its exposure speed is extremely fast, which can be quickly exposed and cured under low ultraviolet energy under DMD lithography rays to complete fine The requirements for rapid mesh making of the pattern are suitable for the rapid mesh making of DMD lithography technology.

Description

technical field [0001] The invention relates to a new environment-friendly photosensitive polymer material, in particular to a high-sensitivity environment-friendly single-component rotary mesh photosensitive adhesive and a preparation method and application thereof. Background technique [0002] Rotary screen printing is a printing technology that uses a scraper to make the color paste in the circular screen made of the pattern printed on the substrate under pressure. This technology can continuously and quickly produce printed textiles or walls in large quantities. cloth, etc., so as to be applied on a large scale. The exquisite patterns of rotary screen printing are realized by rotary screen printing screen plates made of rotary screen photosensitive adhesives through the processes of coating-drying-ultraviolet exposure-developing imaging-heat curing. [0003] DMD lithography technology is currently the most advanced mesh technology in the world. The core of the system i...
