Abstract

The invention relates to a scratch resistant PU (Poly Urethane) floor varnish and a preparation method thereof. The scratch resistant PU floor varnish is prepared from a first ingredient and a second ingredient at weight ratio of (0.8-1.2):(0.8-1.2), wherein the first ingredient is prepared from the following raw materials in parts by weight: 30-50 parts of hydroxy acrylic resin, 20-40 parts of high-hydroxyl number alkyd resin, 0.1-0.5 part of leveling agent, 0.1-0.5 part of antifoaming agent, 1-10 parts of epoxy resin, and 20-40 parts of composite environment-friendly solvent, and the second ingredient is prepared from the following raw materials in parts by weight: 10-40 parts of TDI-TMP, 10-30 parts of HDI (Hexamethylene Diisocyanate) tripolymer, 10-20 parts of moisture curing agent, and 30-50 parts of butyl acetate. By adopting the scratch resistant PU floor varnish disclosed by the invention, the scratch resistance of the varnish surface on the floor is obviously improved, while the other performances of transparency, storage stability and the like are rarely influenced; simultaneously the varnish film is uniform, smooth, and good in adhesion force; the number of the varnish coating layers can be reduced, therefore the cost is reduced; in addition, fracture is unlikely to form to influence the beautiful appearance of the floor.

Description

technical field [0001] The invention relates to an anti-scratch PU bright floor paint and a preparation method thereof. Background technique [0002] At present, PU wood lacquer occupies a very important position in the Chinese market. As the market demand for PU wood lacquer increases and competition intensifies, many higher and newer requirements are put forward for PU wood lacquer, especially for PU glossy floors. Paint requirements on scratch resistance and abrasion resistance. Existing PU floor paints (especially PU bright floor paints) are prone to scratches and wear-resistant problems during use, and it is difficult to meet customer requirements. In the past, the number of coating layers of paint was basically increased to improve The abrasion resistance of the wooden floor increases the amount of paint greatly, which not only increases the cost, but also easily produces cracks and other disadvantages. At the same time, the scratch resistance of the paint film cannot...
