Abstract

The invention discloses a hydrophobic stain-resistant polyurethane interior wall coating. The interior wall coating is prepared from the following components in percentage by weight: 0.1 to 0.5 percent of a pH regulator, 0.2 to 0.7 percent of hydroxyethyl cellulose, 0.1 to 0.4 percent of a preservative, 0.8 to 2 percent of a wetting dispersant, 0.3 to 0.5 percent of a de-foaming agent, 5 to 18 percent of titanium dioxide, 3 to 9 percent of mica powder, 2 to 7 percent of talcum powder, 12 to 26 percent of calcium carbonate, 5 to 10 percent of straw powder, 5 to 10 percent of a water repellent agent, 0.3 to 1 percent of a drier, 15 to 35 percent of polyurethane emulsion, 1 to 1.2 percent of an anti-freezing agent and the balance of water. The water-based ink is prepared from the following components in percentage by weight: 0.2-0.4% of a thickening agent, 0.5-3% of a fluorescent whitening agent, 0.05-0.3% of pigment The key performance of the hydrophobic stain-resistant polyurethane interior wall coating meets the requirements, besides the basic decoration function of the interior wall coating, the coating also has a stain-resistant effect and is particularly suitable for places such as homes and kindergartens, and the later attractiveness and the easy-to-clean property are effectively improved; the invention also discloses a preparation method of the hydrophobic stain-resistant polyurethane interior wall coating, and the hydrophobic stain-resistant polyurethane interior wall coating is developed by screening various emulsions and assistants and researching the dosage ratio.

Description

technical field [0001] The invention relates to the technical field related to paint production, in particular to a hydrophobic stain-resistant polyurethane interior wall paint and a preparation method thereof. Background technique [0002] Now in the process of interior decoration, in order to make the interior more beautiful and the wall smoother, it is usually necessary to use interior wall paint to paint the interior wall, so that it presents different styles and colors, which is more suitable for daily living . [0003] But in daily life, the wall painted with latex paint is easy to get dirty, especially if there are children at home. I often knock over things or paint pictures. Due to the poor density of ordinary latex paint, the stains on it can easily penetrate in and make it difficult to clean. This product adopts high-density polyurethane emulsion and hydrophobic agent to achieve hydrophobicity, It is not easy to penetrate and double protection, which makes the w...
