Waterborne polyurethane floating color sand self-leveling mortar and preparation process thereof
The invention relates to waterborne polyurethane floating color sand self-leveling mortar and a preparation process thereof, and belongs to the technical field of floor coatings. Comprising a component A, a component B, a component C and a component D. The component A is a high-molecular hydroxyl donor, the component B is a high-molecular isocyanate donor, the component C is filler, the component D is self-grinding color paste, and the mass ratio of the four components is 1: (0.9-1.3): (1.5-4.6): (0-0.1). The waterborne polyurethane floating color sand self-leveling mortar provided by the invention is extremely good in mechanical property, extremely low in volatile organic compound (VOC) content (less than 2g/L) and resistant to a strong corrosive medium, can be used for five times in cold and hot cycles at the temperature of-45 DEG C to 175 DEG C, keeps excellent use performance, and has elegant decoration of a traditional color sand floor in appearance.
本发明涉及一种水性聚氨酯浮动彩砂自流平砂浆及其制备工艺，属于地坪涂料技术领域。包括A、B、C和D四个组分，其中，A组分为高分子羟基供体，B组分为高分子异氰酸酯供体，C组分为填料，D组分为自磨色浆，上述四个组分的质量比为：1:(0.9‑1.3):(1.5‑4.6):(0‑0.1)。本发明提供一种机械性能极好，挥发性有机化合物含量(VOC)极低(＜2g/L)，耐强腐蚀介质，可在‑45℃至175℃的冷热循环中五次，且保持优良的使用性能，外观上具有传统彩砂地坪典雅装饰性的水性聚氨酯浮动彩砂自流平砂浆。
