Problems solved by technology

However, polyurethane bright white topcoats for furniture in the market are always difficult to meet customer needs in terms of fullness, leveling and hardness of the paint film.
In theory, such problems can be improved by changing the filler system in the formula. Barium sulfate is also one of the choices. However, due to the easy-to-sink characteristics of barium sulfate and the limitations of the formula system, adding barium sulfate can easily make the paint many disadvantages

Abstract

The invention discloses a nanoscale barium sulfate-containing polyurethane bright white finish for furniture. The nanoscale barium sulfate-containing polyurethane bright white finish comprises a main agent, a curing agent and a diluting agent, wherein the main agent comprises 50-55 percent of synthetic fatty acid resin, 4.0-6.0 percent of butyl acetate, 0.1-0.3 percent of antifoaming agent, 0.1-0.2 percent of flatting agent, 30-35 percent of titanium dioxide, 0.5-1.0 percent of dispersing agent and 5-10 percent of nanoscale barium sulfate; the curing agent comprises 40.0-50.0 percent of toluene diisocynate tripolymer, 20.0-30.0 percent of hexamethylene diisocyanate tripolymer and 20.0-30.0 percent of butyl acetate; the diluting agent comprises 25.0-40.0 percent of butyl acetate, 25.0-30.0 percent of dimethylbenzene and 35.0-45.0 percent of propylene glycol methyl ether acetate. After the nanoscale barium sulfate-containing polyurethane bright white finish forms a film through construction, a finish film has the characteristics of better sand mark shielding capacity, fullness, excellent leveling, high hardness and the like.

Description

technical field [0001] The invention relates to a polyurethane bright white finish paint for furniture containing nano-scale barium sulfate. Background technique [0002] At present, with the improvement of people's material and cultural living standards, the requirements for the aesthetics and decorative effects of home furniture are getting higher and higher, especially the light series. However, polyurethane bright white topcoats for furniture in the market are always difficult to meet customer needs in terms of fullness, leveling and hardness of the paint film. In theory, such problems can be improved by changing the filler system in the formula. Barium sulfate is also one of the choices. However, due to the easy-to-sink characteristics of barium sulfate and the limitations of the formula system, adding barium sulfate can easily make the paint There are many disadvantages. This product adopts the nano-scale barium sulfate produced by the most advanced technology, and i...
