Problems solved by technology

But all have their big limitations: UV coatings are usually applied by roller coating or flow coating, which is more suitable for coating large flat substrates, but not suitable for special-shaped parts, and is restricted by ultraviolet light in coating and coloring; water-based The performance of wood coatings is not as good as that of traditional solvent-based wood coatings
Compared with traditional solvent-based coatings, existing environmentally friendly coatings still have some shortcomings in application and performance

Abstract

The invention belongs to the field of wood coatings and particularly relates to a wood surface coating which can be cured to form a film under any weak light source. The weak light-cured wood coating is composed of two components of A and B. The component A is main paint and is composed of a main resin, sealing wax, an accelerator, a polymerization inhibitor, a thixotropic agent, auxiliaries, an active diluent and a dye. The component B comprises an initiator. The weak light-cured wood coating has solid content near to 100%, is not limited by a wood shape and is a low-VOC emission, excellent performance, widely used, environment-friendly and resource-saving wood coating.

Description

technical field [0001] The invention belongs to the field of wood coatings, in particular to a coating for wood surface coating that can be cured to form a film under any weak light source. Background technique [0002] During the production and use of traditional coatings, solvents and some chemical substances (paint VOCs) will be volatilized into the atmosphere, which not only causes waste of resources, but also endangers the human body and the environment. [0003] The sustainable development strategy requires the coordinated development of the social economy and the environment, absolutely not at the expense of the environment, and at the same time requires the rational use of resources to the maximum extent. As a consumable, coating products, especially the traditional low-solid solvent-based coatings, face huge challenges, and must be completely reformed to meet the requirements of sustainable development strategies. [0004] The development of environmentally friendl...
