Embodiment Construction

[0017] The specific embodiment to realize the preparation method of the photocurable modified polyurethane wood paint of the present invention is: the wood paint is divided into two components: a main agent and a curing agent, and the raw materials of the main agent are selected according to the following weight (%) Preparation:

[0018] Isocyanate-containing polyurethane acrylate resin 65;

[0019] Tripropylene glycol diacrylate 27;

[0020] 2-Hydroxy-2-methyl-1-phenylacetone 5.8 as a cleavage-type photoinitiator;

[0021] Foam-breaking polysiloxane solution 0.7;

[0022] High molecular weight block copolymer 0.7;

[0023] Modified urea solution 0.8.

[0024] The raw material of the curing agent is selected from fatty acid modified polyester resin.

[0025] The production process of the main agent of wood lacquer is as follows: the isocyanate-containing urethane acrylate resin is put into the stirring vessel in advance, and then the tripropylene glycol diacrylate, the fo...

Abstract

The invention provides a preparation method of light-curing polyurethane modified carpentry paint. The light-curing polyurethane modified carpentry paint prepared according to the method solves the problems that common polyurethane carpentry paint is not environment-friendly due to long volatilization cycle, and consecutive operation can not be conducted when the common polyurethane carpentry paint is painted on abnormal-shaped parts. The light-curing polyurethane modified carpentry paint is high in priming paint solid content and thick in paint coating film, and effectively reduces painting times, and can be instantly solidified after painted for multi-layers and irradiated by light. A workpiece leaving after painted can enter next procedure instantly, and therefore consecutive operation is realized, and construction efficiency is remarkably improved, and high environment protection performance is achieved. The light-curing polyurethane modified carpentry paint is good in scratch resistance due to the fact that adhering density is larger than that of polyurethane paint when finish paint is solidified.

Description

technical field [0001] The invention relates to a preparation method of wood lacquer for furniture, in particular to a preparation method of a light-curable modified polyurethane wood lacquer. Background technique [0002] At present, the types of paints commonly used by domestic and foreign furniture manufacturers are: nitro wood paint, acid-cured wood paint, unsaturated resin wood paint, polyurethane wood paint, light-cured wood paint, and water-based wood paint. Among them, polyurethane wood paint and nitro wood paint are widely used at present, accounting for more than 80% of the total market. In terms of performance, the polyurethane wood paint film is full and the hardness is relatively high, but after the paint film is cured, the solvent is not fully volatilized, causing a long volatilization cycle of volatiles, which has a certain impact on the living environment; although the solvent volatilization speed of nitro wood paint is relatively high. Fast, but the paint f...
