Abstract

The invention provides a water-proof emulsion material for laser engraving. The material is composed of epoxy resin, epoxy resin curing agent, polyisocyanate compound with blocked-end groups (hereinafter referred to as blocked isocyanate compound), bonding promoter and emulsifier. The composition further enhances the water resistance of the moderate-temperature cured emulsion material for laser engraving. During the fabrication and the application, the material produces no toxic gas and harmful liquid, and is of significant industrial use value.

Description

Technical field: [0001] The present invention relates to a water-emulsion type cylinder laser plate-making material with water resistance, more specifically, the present invention relates to a water-emulsion type cylinder laser plate-making material with epoxy resin as the adhesive component, especially the medium-temperature Water-emulsion type rotary screen laser plate-making material with significantly improved water resistance after post-curing. Background technique: [0002] There are currently two methods for photosensitive plate-making and laser plate-making for the preparation method of pattern pattern drawing plate (ie pattern screen plate) for printing. [0003] Photosensitive plate-making is to obtain the pattern on the screen coated with photosensitive emulsion by coating film, spraying wax, ink-jet, etc., after exposure, water development and imaging, a negative pattern screen is obtained; laser plate-making is in On the screen plate coated with polymer plate-m...
