Abstract

The invention discloses a surface light-curing odor-free paint for wood and a construction technology of the paint. The surface light-curing odor-free paint for wood is low in environment pollution, rapid in curing speed, energy-saving, capable of a and less in irritation to human body; and through adoption of the paint, the cured product has good performance and a substrate hardly gets yellow after film formation. In addition, the invention also provides the construction technology of the surface light-curing odor-free paint for wood. The surface light-curing odor-free paint for wood comprises the following components by weight percent: 25-45% of bisphenol-A epoxy acrylate, 8-10% of urethane acrylate, 35-45% of trimethylopropane triacrylate, 1-5% of 4-phenyl-benzophenone, 1-5% of dimethylaminobenzoate, 8-12% of filler and 0.1-1% of additives, wherein the additives include defoaming agent, dispersing agent and flatting agent. The invention can be widely applied to the production manufacturing field of flat plate coating.

Description

technical field [0001] The invention relates to a light-cured deodorizing coating for wood surfaces and a construction process. Background technique [0002] Traditional coatings such as PU coatings, NC coatings, PE coatings, and water-based coatings are commonly used in ordinary coatings. Now water-based coatings and UV light-curing coatings are developing rapidly, especially UV light-curing coatings, which are free of volatile organic compounds ( VOC), low environmental pollution, fast curing speed, energy saving, good performance of cured products, suitable for high-speed automatic production and other advantages have become the main substitutes for traditional coatings. Existing UV photocuring coatings often use small molecule photoinitiators such as BP, 1173 (HMPF) or 184 (HCPK), which provide free radicals during photocuring and also make these small molecules remain in the paint film, and gradually Migrate to the surface of the paint film, release odor and toxicity, ...
