Abstract

The invention relates to the technical field of a paint, and concretely discloses an aqueous polyurethane paint and a preparation method and an application thereof. The aqueous polyurethane paint comprises the following components in parts by weight: 15-35 parts of organic silica glass resin, 25-50 parts of an aqueous hydroxy-acrylic resin emulsion, 5-20 parts of a curing agent, 2-5 parts of a cosolvent, 1-5 parts of organic silicone powder, 1-5 parts of nano alumina, 0.5-2 parts of nano zirconia, 0.1-3 parts of nano negative ion powder, 0.05-0.5 parts of nano zinc oxide, 0.1-1 part of silicasol, 0.1-0.2 parts of a pH conditioning agent, 0.1-0.2 parts of an antifoaming agent, 2-5 parts of a film-forming auxiliary agent, 0.3-0.5 parts of a dispersant, 0.3-0.5 parts of a base material wetting agent, 5-10 parts of deionized water, and 0.5-1 part of a thickening agent. The aqueous polyurethane paint has the advantages of excellent hardness, water resistance, wear resistance and antibacterial activity.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based polyurethane coating and a preparation method and application thereof. Background technique [0002] In daily life, due to the long-term use of the surface of ceramic tiles and coffee tables, it is easy to cause scratches, especially the transparent packaging materials covering the surface of marble coffee tables are easy to fall off, exposing the rough stone surface, thus losing the beautiful luster. Therefore, the coatings on the surface of ceramic tiles, coffee tables and other materials must be high-gloss, beautiful, water-resistant, and wear-resistant. However, the current traditional coatings have poor water resistance and abrasion resistance, and cannot be repaired. After repairing, there are obvious traces that affect the appearance. If ceramic tiles, coffee tables and other materials are not properly maintained during use, bacteria will grow and multiply o...
