Problems solved by technology

[0004] However, water-based polyurethane flooring also has certain problems. Due to its large surface tension, if there is oil or dust on the foundation during paving, shrinkage cavities will easily occur, and the abrasion resistance of water-based polyurethane flooring is currently still low. It needs to be improved for more durable use, so the market needs an anti-shrinkage polyurethane self-leveling floor material

Abstract

The invention belongs to the technical field of polyurethane and specifically relates to a polyurethane self-leveling floor material and a preparation method thereof. The polyurethane self-leveling floor material is prepared form a component A and a component B, wherein the component A comprises a resin emulsion, water, modified castor oil, a thickener, a defoaming agent, nano silica, filler, pigments, a leveling agent, an anti-cratering agent, a mildew preventive and a wetting dispersant; the component B is a curing agent. Cratering is effectively reduced during spreading, and the product hasgood hardness and superhigh wear resistance.

Description

technical field [0001] The invention belongs to the technical field of polyurethane materials, and in particular relates to a polyurethane self-leveling floor material and a preparation method thereof. Background technique [0002] Due to its excellent weather resistance, durability, low cost, waterproof, anti-corrosion, and bright, polyurethane floor coatings are widely used in indoor environmental protection floor laying and outdoor hard court laying, especially outdoor basketball courts in schools, communities, etc. Badminton courts, etc., are also used in factories, parking lots, etc. [0003] Due to the presence of a large amount of volatile organic solvents in common solvent-based acrylic floor coatings, it is not environmentally friendly, consumes a lot of solvent thinners, and has a greater toxic effect on construction workers. The water-based acrylic paint basically does not contain organic solvents and has very low VOC. It is an environmentally friendly paint, and...
