Problems solved by technology

However, at present, most of the deodorizing products launched by many manufacturers use the methods of adding flavors and masking agents, which can only cover up the pungent smell of benzene solvents in the paint film but cannot fundamentally solve the problem. Has a strong smell and cannot meet the needs of customers
Disclosed as CN1557894A " a kind of polyurethane matt white finish for woodware, its invention is to propose a kind of quick-drying, anti-yellowing matte white finish, does not mention " no benzene clean taste " problem, therefore The present invention has certain difference with above-mentioned invention aspect function effect

Abstract

The invention relates to polyurethane matte white finish coat for non-benzene and odor-free furniture, which consists of a main agent, a curing agent and a diluent, wherein the main agent comprises hydroxyl acrylic resin, titanium white, solvent, a defoaming agent, a flatting agent, an anti-settling agent, a dispersing agent and a flatting agent; the curing agent comprises a toluene diisocynate tripolymer, toluene diisocynate-trimethylolpropane addition product and butyl acetate; and the diluent comprises the butyl acetate, cyclohexanone and propylene glycol monomethyl acetate. By adopting the technical scheme, the polyurethane matte white finish coat has the advantages that: an obtained paint film has less residual solvent and is tasteless after 12 hours; a formula does not contain chemical substances harmful to body health of human beings, such as benzene, methylbenzene, dimethylbenzene, other aromatic solvents and derivatives, methanol, glycol ether ester solvents, halogenated hydrocarbon and the like, and the excellent decorative and protective effects of the conventional polyurethane (PU) dual-component furniture paint are reserved in the formula; and the polyurethane matte white finish coat is easy to construct and is applicable to various construction modes such as spraying, electrostatic spraying and brush coating.

Description

technical field [0001] The invention relates to a polyurethane matte white finish, in particular to a polyurethane matte white finish for furniture without benzene and net odor. Background technique [0002] At present, with the improvement of people's material and cultural living standards, household products are no longer limited to general aesthetics and decorative effects, but more attention is paid to health, comfort, and environmental protection. Although the alkyd polyurethane white topcoat for wooden furniture on the market has a good decorative effect, it contains substances harmful to human health such as benzene, and the solvent and a small amount of free TDI remain for a long time, are not easy to volatilize, and the odor is difficult to eliminate. Therefore, it is particularly necessary to develop new furniture paint products that are benzene-free, odor-free, low in free TDI, and harmless to human health, and have become a focus of attention and development dire...
