Abstract
The invention relates to anti-scratch UV photocuring odorless matte white finish paint. The white finish paint is characterized in that the white finish paint comprises following raw materials by mass: 15-20 parts of epoxy acrylate, 5-10 parts of aliphatic urethane acrylate, 7-15 parts of a high-functional active monomer, 15-25 parts of a bifunctional active monomer, 4-12 parts of extinction powder, 0.3-0.5 part of an anti-settling agent, 0.1-0.3 part of an antifoaming agent, 0.2-0.4 part of a leveling agent, 1-2 parts of a dispersing agent, 3-5 parts of nepheline syenite powder, 0.5-2 parts of wax powder, 20-30 parts of titanium dioxide and 4-6 parts of a photoinitiator. The product provided by the invention has the advantages of quick drying, high hardness, wear resistance, excellent scratch resistance, easy curing and no residual smell, and is applied to coating of white cupboards, wooden doors and handicrafts, and the production efficiency can be greatly improved.
Description
technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a scratch-resistant light-curing odor-free matte white finish. Background technique [0002] UV light-curing coating is a kind of high-efficiency, environmental protection, energy-saving, high-quality light-curing material, and it is a kind of furniture paint widely used at present. Because the coating film is cross-linked and cured, it has high hardness, good wear resistance, and the product is scratch-resistant and friction-resistant, so it is widely used in office furniture, cabinets, handicrafts, etc. Moreover, in recent years, the cabinet series products have developed extremely rapidly, especially in white cabinets and handicrafts. At the same time, consumers have higher and higher requirements for product performance. Specific to UV white topcoat, higher requirements are put forward for anti-scratch and odor of daily necessities. For example, put some keys, ...
