[0033] The preparation method of this coating is as follows:
[0034] The first step, after mixing water and modified epoxy resin, add graphene oxide, coupling agent, defoamer, substrate wetting agent, leveling agent and dipropylene glycol butyl ether while stirring, and then continue stirring for 25-30min , and then add the thickener, after adding, continue to stir for 10-20min, filter to obtain the primer;
[0035] The second step is to mix the primer and the curing agent evenly to prepare the coating.
Embodiment 1
[0037] A high-grade wood handicraft coating, including a primer and a curing agent, the primer includes the following raw materials in parts by weight: 60-70 parts by weight of modified epoxy resin, 2-3 parts of graphene oxide, 0.8-1 parts of coupling agent, and defoaming agent 0.2-0.3, 0.4-0.5 parts of thickener, 0.7-0.9 parts of substrate wetting agent, 0.1-0.2 parts of leveling agent, 4-5 parts of dipropylene glycol butyl ether, 12-15 parts of water;
[0038] The curing agent is polyisocyanate curing agent WT101, wherein the ratio of the amount of hydroxyl groups to isocyanate groups in the modified epoxy resin is controlled to be 1:1.3-1.4.

Abstract
The invention discloses a high-grade woodware artware coating. The high-grade woodware artware coating comprises a primer and a curing agent, wherein the primer is prepared from the following raw materials in parts by weight: 60 to 70 parts of modified epoxy resin, 2 to 3 parts of graphene oxide, 0.8 to 1 part of a coupling agent, 0.2 to 0.3 part of an antifoaming agent, 0.4 to 0.5 part of a thickener, 0.7 to 0.9 part of a base material wetting agent, 0.1 to 0.2 part of a leveling agent, 4 to 5 parts of dipropylene glycol butyl ether and 12 to 15 parts of water; the curing agent is a polyisocyanate curing agent, and the molar ratio of hydroxyl to isocyanate groups in the modified epoxy resin is 1: 1.3-1.4. According to the invention, the modified epoxy resin is used as a resin matrix of the coating, a modifier is used for graft modification of the epoxy resin chain, and then the modified epoxy resin chain is copolymerized with the polyurethane, so that the performance complementation of the epoxy resin and the polyurethane can be realized, and a coating film has excellent impact resistance, adhesive force, flexibility, hardness, gloss and liquid medium resistance; the obtained coating is suitable for surface coating of high-grade woodware artware, and a paint film with high protection performance is formed on the surface of the coating.
Description
technical field [0001] The invention belongs to the field of paint production, and in particular relates to a paint for high-grade wood crafts and a preparation method thereof. Background technique [0002] As we all know, wooden handicrafts require meticulous craftsmanship. Wooden products must be perfect in terms of wood selection, pattern depiction, beautiful appearance, and use time. Because wood crafts are very popular in Japan, Singapore, Taiwan, Malaysia and other countries, the climate of these countries has its own unique side. Especially affected by the marine climate and environment, wood products are required to have good adaptability to temperature and humidity, and good corrosion resistance. Considering the use function of wooden products, most of them are high-grade handicrafts, so the requirements for their appearance are very strict. This also puts high demands on the paint and coating process. It not only requires good plane effect and sharpness of image...
