Problems solved by technology

At present, when making closed furniture materials in the market, oil-based paints are often used for finishing. Oil-based paints emit a strong pungent smell during construction. Most of them are formaldehyde and benzene volatile substances, which seriously endanger human health. Water-based paints can replace oil-based paints. To avoid the release of organic solvents, the existing water-based furniture varnish can achieve the effect of paint finishing on ordinary flat solid wood panels, but the existing water-based wood varnish has poor stain resistance and poor weather resistance

Abstract

The invention provides oily-pen-resistant waterborne woodware varnish and a preparation method thereof. The varnish comprises a component A and a component B, wherein the component A comprises, by weight, 60-80 parts of waterborne hydroxylated acrylic resin, 0.05-0.5 part of pH regulator, 0.1-0.5 part of waterborne defoaming agent, 0.1-0.5 part of waterborne wetting agent, 0.1-0.5 part of waterborne leveling agent, 1-5 parts of coalescing agents, 5-10 parts of nano additives, 5-10 parts of anti-doodling auxiliaries, 0.5-4 parts of wear-resistant auxiliaries, 0.05-2 parts of bactericide and 1-20 parts of water; the component B comprises, by weight, 15-30 parts of curing agent. The anti-doodling auxiliaries and the nano additives are added, so that the anti-doodling and anti-dirt propertiesof a coating are remarkably improved; the anti-doodling auxiliaries are preferably polydimethylsiloxane anti-doodling auxiliaries containing hydroxyl functional groups, and the anti-doodling auxiliaries contain hydroxyl and can participate in a curing reaction, so that the anti-doodling performance of paint film is further improved.

Description

technical field [0001] The invention relates to the technical field of wood ware formulations, and specifically discloses an oil-resistant pen water-based wood varnish and a preparation method thereof. Background technique [0002] Water-based wood lacquer is a coating product that is applied on the surface of wooden furniture or wood products. In addition to its protective effect on wood products, it also needs to have a certain decorative effect. At present, when making closed furniture materials in the market, oil-based paints are often used for finishing. Oil-based paints emit a strong pungent smell during construction. Most of them are formaldehyde and benzene volatile substances, which seriously endanger human health. Water-based paints can replace oil-based paints. To avoid the release of organic solvents, the existing water-based furniture varnishes can achieve the effect of paint finishing on general flat solid wood boards. However, the existing water-based wood var...
