Problems solved by technology

[0002] Floor materials commonly used in the traditional market, such as epoxy floor and solvent-based polyurethane floor, etc. contain solvents, pollute the environment, and most of them are constructed by hand, the construction efficiency is low, and there are defects such as scratches and vesicles on the surface.
The spray polyurea technology has a very fast reaction speed, and the gel time is usually only about 10 seconds. Therefore, the surface of the sprayed polyurea floor cannot be leveled into a flat surface, and there are many small particles on the surface, so the surface is visually unattractive. , the bigger disadvantage is that it is easy to hide dirt and dirt, and it is not easy to clean
If the gel time of ordinary polyurethane spraying materials is extended, the system will often cause foaming, which will greatly affect the performance of the material

Abstract

The invention belongs to the technical field of elastic terrace coating, and in particular relates to a leveling type terrace material, and a preparation method and a spray-coating method thereof. The leveling type terrace material consists of a prepolymer component A and a curing agent component B, wherein the component A consists of the following raw materials in percentage by mass: 45 to 65 percent of isocyanate and 35 to 55 percent of polyether polyol; and the component B consists of the following raw materials in percentage by mass: 60 to 80 percent of hydrophobic polyol, 20 to 36 percent of a chain extender, 0.3 to 1 percent of a leveling agent and 0.3 to 0.6 percent of a catalyst. The steric hindrance chain extender and the hydrophobic polyol are adopted, so the reaction speed is greatly reduced, the flat and smooth surface with high leveling property is achieved, and bubbling is avoided; and the construction efficiency is high, a solvent is not provided, environmental friendliness is achieved, the surface defects such as scratch and bubbles are avoided, the final product has high wear resistance and elasticity, and the elongation percentage is several times higher than that of an epoxy terrace.
