Embodiment 2

[0022] The difference between this example and Example 1 is that the UV-curable wood coating is composed of the following components by weight percentage: 40% epoxy resin, 32% aliphatic polyurethane resin, 8% monomer EO-HDDA, 8% monomer EO -TMPTA9.6%, monomer HEMA5%, photoinitiator 5%, leveling agent 0.2%, defoamer 0.2%.

[0023] In this embodiment, the epoxy acrylate is 621-100 epoxy acrylate; the aliphatic urethane acrylate is 6145-100 aromatic urethane acrylate; the defoamer is BYK-8800 defoamer. The leveling agent adopts TEGO-410 leveling agent; the photoinitiator adopts IHT-PI6022 photoinitiator, and in practical application, the photoinitiator can also adopt other photoinitiators, such as but not limited to IHT-PI907 Photoinitiator or 184 photoinitiator or IHT-PIPBZ photoinitiator or IHT-PI917 photoinitiator.

[0024] Experiments have proved that the UV-curable wood coatings prepared by the formula of this embodiment have the following advantages:

Abstract

The invention discloses a low-odor ultraviolet-curing woodenware paint formula. The paint comprises the following components by weight percentage: 35-50% of epoxy resin, 25-35% of aliphatic polyurethane resin, 8-12% of a monomer EO-HDDA, 8-12% of a monomer EO-TMPTA, 4-7% of a monomer HEMA, 3-6% of a photoinitiator, and 0.2-1% of an auxiliary agent. The auxiliary agent comprises a leveling agent and an antifoaming agent. The prepared paint has the advantages of good adhesive force, high heat resistance, low benzene content, low odor before and after curing is carried out, and little influence on human body.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to a low-odor ultraviolet light curing wood coating formula. Background technique [0002] Ultraviolet light-curing coatings refer to the photoinitiator (Initiator) in liquid coatings being excited to become free radicals or cations under the irradiation of ultraviolet rays (Ultra-Violet), thereby triggering reactive substances (Oligomer or A chemical reaction occurs between the monomers, which eventually leads to the formation of the body structure, thereby curing the paint. UV light-curing coatings are mainly used in wood, paper, plastic coating, glass, metal materials, liquid crystal panels and other materials. [0003] In recent years, UV-curable coatings have been widely used in the fields of wood furniture and wooden doors, and will be favored by more and more furniture and wooden door companies in the next few years. However, as a coating, it is inevitable to release some odoro...
