Abstract

The invention discloses an odor-free yellowing-resistant UV (ultraviolet) curing coating and a preparation method thereof. The odor-free yellowing-resistant UV curing coating comprises the following components in parts by weight: 30-45 parts of resin, 35-55 parts of reactive diluent, 6-10 parts of delustering agent, 0.8-1 part of wax powder, 0.3-0.5 part of anti-settling agent, 0.1-0.3 part of defoaming agent, 0.2-0.5 part of flatting agent, 0.1-0.5 part of dispersing agent, 3-5 parts of photoinitiator, 0.5-1 part of BP, 0.5-1.5 parts of active amine and 0.01-0.05 part of polymerization inhibitor, wherein the resin is modified epoxy acrylic ester resin, aliphatic urethane acrylate resin and hyperbranched polyester acrylate resin. The odor-free yellowing-resistant UV curing coating disclosed by the invention has the performances of low odor and high yellowing resistance, and can meet higher requirements of the UV curing coating on low odor and yellowing resistance in the furniture industry.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a clean odor and anti-yellowing UV-curable coating and a preparation method thereof. Background technique [0002] In recent years, ultraviolet (UV) light-curing 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. Signs such as the rapid increase in the output of furniture and wooden door UV light-curing coatings indicate that UV light-curing coatings will be a rapid development in the entire wood product industry. [0003] As we all know, based on the concept of environmental protection, the furniture industry is sensitive to the smell, not only the smell of the paint itself, but also the smell of the paint film after the paint is cured, and the smell emitted by the finished furniture during use. At the same time, white products in the furniture industry have diff...
