Abstract

The invention relates to a high-hardness super-wear-resistant two-component waterborne polyurethane terrace coating, and belongs to the technical field of terrace coatings. The coating comprises a component A and a component B in a weight ratio of (3-5):1; the component A comprises the following raw materials in parts by weight: 10-15 parts of water, 0.2-0.8 part of a water-based dispersing agent,0.5-2 parts of a water-based wetting agent, 0.5-2 parts of a water-based defoamer, 0.5-2 parts of a water-based leveling agent, 25-35 parts of wear-resistant powder and 45-55 parts of a water-based polyurethane dispersion body; the component B comprises 15-25 parts of a water-based polyurethane curing agent. After the ground is brushed with the terrace coating, the ground has the characteristicsof high hardness and super wear resistance, in addition, the terrace coating also has the advantages of no dust, no yellowing, bright color, no fading, no pollution and the like, and the attractiveness and the practicability of the ground are greatly improved.

Description

technical field [0001] The invention relates to a high-hardness and super wear-resistant two-component water-based polyurethane floor coating, which belongs to the technical field of floor coatings. Background technique [0002] At present, the floor materials on the market are divided into two categories: inorganic floor materials and organic floor materials. Organic floor materials are further divided into epoxy floor, polyurethane floor, acrylic floor and so on. Due to its own performance, organic floor materials have great advantages over inorganic floor materials. The polyurethane floor material is one of the products with the highest performance among the organic floor materials. [0003] Polyurethane floors are divided into solvent-based, solvent-free and water-based. Among them, although solvent-based products have excellent performance and low price, they are seriously polluting the environment and are gradually being eliminated. Solvent-free products have excell...
