Abstract

The invention relates to the field of coatings, in particular to a UV light-cured wood coating and a preparation method thereof. The wood coating comprises the following components in parts by weight: 20-50 parts of resin, 20-40 parts of a monomer and 3-7 parts of an initiator, wherein the resin is epoxy acrylate or modified bisphenol A epoxy acrylate; the monomer is a mixture of trimethylolpropane triacrylate and diethylene glycol diacrylate; the initiator is a mixture of active amine and one or more of TPO, PBZ and OMBB. The wood coating provided by the invention can be cured under UV light, and the wood coating can realize complete odor removal; meanwhile, the wood coating has good viscosity, heat resistance, stability, leveling property and adhesive force, and relatively high curing speed.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV light-cured wood coating and a preparation method thereof. Background technique [0002] In recent years, UV-curable coatings have been rapidly developed and widely used in wood furniture and other fields. Combined with market feedback, higher requirements are put forward for the additional effects of UV-curable coatings, especially for odor; the existing UV-curable coatings have a relatively strong odor, so apply them to children's study tables, wardrobe interior panels, etc. When entering the field, it will cause certain damage to the human body. Therefore, it is a technical problem that those skilled in the art urgently need to solve to develop a low-odor or even clean-taste UV-curable coating. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The object of the present invention is to provide a kind of wood coating, the residual s...
