Embodiment Construction

[0014] The principle of the present invention is to obtain a new type of photocurable glas by selecting suitable photocurable resins and extremely low toxicity and irritating active monomers to solve the above-mentioned shortcomings. The base color can also fill the wood conduit, reduce the coating amount of the primer, no organic solvent volatilizes, and the curing is completed within 5 seconds under the irradiation of ultraviolet light, with high efficiency and suitable for industrial production.

[0015] Production formula of the present invention is:

[0016] raw material name Mass fraction % Modified epoxy acrylic resin 10-20% active monomer 40-50% Photoinitiator 5-8% color essence 0-10% Wetting and leveling agent 0.1-0.5% Dispersant 0.5-1% filler 10-15% fumed silica 1-5%

[0017] Wherein, the modified epoxy acrylic resin is at least one of ETERNAL6202, ETERNAL622-100, CN2101, CN112C60, EB3702, LR8986; the act...

Abstract

A rib crack or bogging resistant environmentally-friendly photocurable high-filling GLAZE coloring agent comprises, by mass, 10-20% of modified epoxy acrylic resin, 40-50% of an active monomer and 5-8% of a photoinitiator, and has the advantages of good dispersion stability and adhesion, high hardness, good leveling, good fullness, fast drying speed, high production efficiency, few organic volatile matters, and simple and convenient construction. The coloring agent has good compatibility and interlayer binding force with various aqueous priming paints and finishes, well improves the wood grain contrast of the surface of wood, and also has the characteristics of safety, environmental protection, no pungent smell, uniform coloring, plump filling, and excellent color fixation.

Description

technical field [0001] The invention relates to IPC International Patent Classification C09C inorganic material coloring or filling technology or C09D coating composition coating technology, especially an environmentally friendly light-curing high-filling Grace colorant for explosion-proof ribs or sags. Background technique [0002] At present, the coating process of furniture primer is mainly based on polyurethane (Polyurethane, abbreviated as PU, referred to as polyurethane) or unsaturated polyester paint (PE). Good focus performance. However, the content of volatile matter (VOC) is high (about 50-60%), the pot life is short (the prepared paint needs to be used up as soon as possible), it is greatly affected by temperature, and the production efficiency is low, which hinders the development of furniture enterprises. UV paint is the abbreviation of Ultraviolet Curing Paint (Ultraviolet Curing Paint), also known as photoinitiated coatings, photocured coatings, after being c...
