High-performance single-component polyurethane waterproof coating and preparation method thereof

The invention provides a high-performance single-component polyurethane waterproof paint and a preparation method, and relates to the technical field of paints.The main method includes the steps that special organic modified layered silicate is stripped into a two-dimensional sheet-shaped nano-structure in the paint synthesis process, and the two-dimensional sheet-shaped nano-structure is formed by means of the small size of the two-dimensional sheet-shaped nano-structure; the characteristics of large specific surface area, high surface energy and the like improve the interaction with a polyurethane molecular chain segment, and enhance the cohesion of a polyurethane hard segment structure, thereby improving the mechanical properties of the polyurethane waterproof coating. By adjusting formula composition design and synthesis process conditions, the single-component polyurethane waterproof coating with good storage stability and high mechanical properties can be obtained. 本发明提供了一种高性能单组分聚氨酯防水涂料及制备方法，涉及涂料技术领域，主要
