Problems solved by technology

The defect of this patent is that there is no residual irritating smell after curing, and the function of "clean taste" cannot be achieved. Moreover, the manufacturing process before curing still pollutes the environment
At the same time, some compounds mentioned in the technical background of the patent formula contain benzene before being exposed to light, and it does not increase after being exposed to light; it shows that benzene remains in the manufacturing process or has already caused a great impact on human health and the surrounding environment

Abstract

The invention relates to an odorless ultraviolet-curing wood lacquer and a preparation method thereof. The wood lacquer is prepared from the following components in percentage by weight: 45-65% of ultraviolet-curing resin, 10-25% of reactive monomer, 5.0-15% of talcum powder, 5.0-15% of transparent powder, 0.5-1.0% of gas-phase silicon dioxide, 1.0-5.0% of photoinitiator, 0.2-0.5% of defoaming agent, 0.2-1.0% of leveling agent and 0.2-1.2% of wetting agent. The odorless ultraviolet-curing wood lacquer does not have irritating odor before and after construction, does not contain benzene, and can be used immediately after construction; and meanwhile, the surface effect and fullness are not inferior to those of nitrocellulose dope, unsaturated paint or polyester paint.

Description

technical field [0001] The invention relates to an ultraviolet light-curable coating for wood products, in particular to an odor-cleaning ultraviolet light-curable wood transparent varnish for wood products. Background technique [0002] UV-curable coatings have developed rapidly due to the advantages of short recoating time, high production efficiency, and environmental protection. However, nitro coatings, unsaturated resin coatings, and polyurethane coatings are all inferior to UV light-curing coatings due to their environmental protection, efficiency, and production costs. Especially in terms of environmental protection, it is also inferior to UV photocurable coatings, and the formulations commonly used in the existing UV photocurable coating technology have been systematically analyzed and tested. Combined with the experimental data of the market, the regularity Recognition, a formula composed of a variety of acrylic compounds, the mechanism of benzene produced during t...
