Abstract

The invention discloses woodenware coating formed by matching of hydroxyl acrylic resin and synthetic fatty acid modified short-oil alkyd resin and preparation method of the woodenware coating. The preparation method of the woodenware coating comprises the step of taking hydroxyl acrylic resin, the synthetic fatty acid modified short-oil alkyd resin, an aliphatic diisocyanate curing agent, an isocyanate tripolymer curing agent, inorganic metallic oxide pigment, a polyurethane polymeric dispersant, anti-precipitant polyethylene wax, extinction powder, an acrylates flatting agent, a silicon oils flatting agent, an organic tin drier, an assistant and an esters solvent as raw materials for making white finish of woodenware. The invention also provides a preparation method of the white finish of the woodenware. The woodenware coating disclosed by the invention is based on the matching of the hydroxyl acrylic resin and the synthetic fatty acid modified short-oil alkyd resin, has the characteristics of high fullness and yellowing resistance and has the characteristic of quick drying at the same time.

Description

technical field [0001] The invention relates to a home decoration wood finish paint, in particular to a wood paint made of hydroxyl acrylic resin and synthetic fatty acid modified short oil alkyd resin and a preparation method thereof. Background technique [0002] Solvent-based wood lacquers, which have long been known, are used due to their excellent properties such as scratch, chemical and weather resistance as well as high gloss. Furthermore, for reasons of environmental protection it is necessary to provide coating compositions which can be applied with lower and lower solvent contents and are therefore required to be applied with higher and higher solids contents (so-called high solids). Those topcoats that do not comply with the volatile organic compound (VOC) limit based on the total weight at the time of application are difficult to comply with the volatile organic compound (VOC) limit because they are diluted by solvent blending during application. The volatile o...
