Problems solved by technology

However, when the existing water-based light-curing materials are actually used, the glossiness of the cured film formed on the wood surface is low, which may affect the aesthetics to a certain extent in some applications; The hardness of the cured film formed by the light-cured material is also poor, and it is easy to be scratched or scratched in daily life
Therefore, the prior art has the problems of poor gloss and low hardness

Abstract

The invention discloses an aqueous photocuring material and a preparation process thereof. The aqueous photocuring material is prepared from the following components in parts by weight: 45-55 parts ofa waterborne polyurethane acrylate emulsion, 18-22 parts of an aqueous aliphatic polyurethane dispersoid, 9-11 parts of an anionic polyurethane acrylate emulsion, 2.3-2.5 parts of an emulsifier, 2.5-3.5 parts of a photoinitiator, 0.8-1.3 parts of a wetting agent, 0.3-0.5 part of a flatting agent, 0.3-0.5 part of a feeling agent, 0.1-0.3 part of a defoamer, 0.3-0.4 part of a thickener and 9-11 parts of deionized water. The components are mixed and dispersed in proportions to obtain the aqueous photocuring material. The aqueous photocuring material has the characteristic of improving the glossiness and hardness of a cured film effectively.

Description

technical field [0001] The invention relates to a photocurable material, in particular to a water-based photocurable material and a preparation process thereof. Background technique [0002] The development of light-curing materials in my country began in the early 1970s, and industrial production began in the 1990s. Water-based light-curing materials are a new generation of light-curing materials that have recently emerged. They have the characteristics of fast curing speed and high production efficiency. ; At the same time, since water-based light-curing materials do not need to use active diluents when used, they will not produce pungent odors and are very environmentally friendly; in addition, water-based light-curing materials also have the characteristics of safety and relatively simple construction; so water-based light-curing materials Curing materials have developed rapidly in recent years and are widely used in wood and other fields. However, when the existing water...
