Problems solved by technology

However, its disadvantages are: because epoxy resin is a rigid material, its wear resistance, low temperature resistance, and surface scratch resistance are poor; its weather resistance is poor, it is easy to age, and its service life is short
Compared with epoxy floor coatings, polyurethane floor coatings have better wear resistance and weather resistance, but the hardness is not enough

Abstract

The invention discloses high-hardness two-component waterborne polyurethane floor paint and a preparing method thereof. The floor paint is formed by evenly mixing a first component and a second component by the mass ratio of 10:1. The second component is prepared from, by mass, 7%-15% of deionized water, 0.5%-1.5% of modified polymer dispersant, 0.4%-0.9% of multifunctional auxiliary, 0.1%-0.3% of non-ionic wetting agent, 1%-25% of pigment, 5%-30% of filler, 40%-55% of hydroxyl acrylic dispersion, 3%-7% of inorganic additive, 2%-8% of high-strength ceramic microspheres, 0.3%-0.5% of polyether defoaming agent, 0.2%-0.3% of BIT preservative and 0.5%-2.5% of polyurethane thickening agent. The high-hardness two-component waterborne polyurethane floor paint prepared through the method is high in paint film hardness and excellent in abrasion resistance and other physical and chemical properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-hardness two-component waterborne polyurethane floor coating and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the construction industry, floor coatings have entered a period of prosperity and development. At the same time, people's requirements for floor coatings are getting higher and higher. In the prior art, epoxy resin, as the earliest resin material used in floors, is the most mature technology and the largest proportion. [0003] The main advantages of resin floor coatings are high hardness and good acid and alkali resistance. However, its disadvantages are: because epoxy resin is a rigid material, its wear resistance, low temperature resistance, and surface scratch resistance are poor; its weather resistance is poor, it is easy to age, and its service life is short. Compared with epoxy floor c...
