Problems solved by technology

Traditional solvent-based floor materials contain about 50% organic solvents. During the manufacturing, processing, drying and curing of coatings, a large amount of volatile organic compounds (VOC) are released into the atmosphere, which has a negative impact on the human ecological environment. cause great pollution and threats

Abstract

The invention discloses a solvent-free polyurethane-acrylate floor material, comprising assemblys A and B, the raw material compositions of the assembly A comprise trimethylol propane, 2,2,4-trimethylhexamethylene diisocyanate, di(propylene glycol) methyl ether acetate, color paste, kaolin, talc powder, precipitated barium sulfate, N,N-dimethylcyclohexylamine, BYK-358N, BYK-066N and BYK-163; and the raw material compositions of the assembly B comprise acrylic resin, diethylene glycol and dibutyltin diacetate. The solvent-free polyurethane-acrylate floor material of the invention is green and friendly to environment, is applicable to various fields, is suitable for indoor and outdoor application, has high decorative property, good weather resistance, good wear resistance, good impact resistance, good hardness, good anti-slip property, good temperature-change resistance, and good adhesion even without a grounding primer, and can be combined with epoxy, cement, polyurethane and other foundations for use with high gloss.

Description

technical field [0001] The invention belongs to the field of floor materials, and in particular relates to a solvent-free polyurethane acrylic floor material. Background technique [0002] The floor refers to the use of specific materials and processes to carry out construction treatment on the original ground and present a certain decorative and functional ground. It is suitable for some places that require relatively high sanitary conditions, such as hospital floors, food factory workshop floors, and pharmaceuticals. The floor of the workshop, the floor of the laboratory building, the floor of the machine room, etc.; with the improvement of people's living standards, the requirements for the floor have become higher, in addition to requiring a certain strength, stiffness, waterproof, moisture-proof, warm, wear-resistant, durable In addition to corrosion and other performance, in some places (such as track and field, sports field, etc.), the floor is also required to have t...
