Problems solved by technology

Although this technology can use the liquid MDI in the low-viscosity B component to balance the A component with a certain viscosity to reduce the final construction viscosity of the system, but the liquid MDI with an NCO equivalent of 127 is almost MDI monomer, and the temperature is below 30 ° C. There is a tendency to solidify, so it will be very difficult to construct in winter. At the same time, MDI monomer is also volatile, which will cause certain hazards to constructors and users.

Abstract

The invention relates to a solvent-free polyurethane wear-resistant terrace paint and a preparation method thereof. The paint is composed of a component A and a component B, wherein the component A comprises the following components by mass parts: 60-80 parts of solvent-free hydroxyl-terminated epoxy resin, 1-13 parts of coloring pigment, 15-22 parts of wear-resistant filling material, 0.2-0.5 part of defoaming agent, 0-0.3 part of drier and 3-5 parts of oxazolidine dewatering agent; and the component B is 100 mass parts of solvent-free isocyanate-terminated prepolymer. When the paint is used, the component A finished product and the component B finished product are mixed and stirred uniformly at a ratio of 3:1 to obtain the solvent-free polyurethane wear-resistant terrace paint. According to the invention, the terrace paint can be cured at low temperature, is free of volatile organic compounds in the system, is low in residual isocyanate monomer content, can improve coating performance, and is suitable for terrace decoration and protection with wear-resistant and dustless requirements in plants, shops, guesthouses, gymnasia, stations, parking lots and other places.

Description

technical field [0001] The invention relates to a solvent-free polyurethane wear-resistant floor coating and a preparation method thereof, belonging to the technical field of floor coatings. Background technique [0002] In recent years, with the rapid development of my country's industry and the continuous advancement of urbanization, large-scale industrial workshops, supermarkets, garages, cultural and entertainment venues and other buildings have emerged, which has driven the rapid development of floor coatings. Modern buildings require the ground to be clean and beautiful, wear-resistant and heavy-pressure resistant, oil-resistant and anti-corrosion. Different requirements for building floors. At present, under the dual guidance of national industrial policies and environmental protection policies and regulations, low-VOC, non-toxic and pollution-free environmentally friendly floor coatings are becoming more and more popular; solvent-free floor coatings as an environmen...
