Abstract
The invention relates to a scratching-resistant waterproof coating compound. The scratching-resistant waterproof coating compound is made of a montmorillonite material modified by lauryl ammonium chloride and triethanolamine, and the modified montmorillonite material is excellent in dispersity, thickening performance and thixotropy and capable of improving stability of the coating compound. By adoption of modified nano compound powder in specific ratio, coating strength, toughness and scratching resistance can be effectively improved after the nano compound powder is subjected to surface modification. Owing to mutual synergy of specific compositions of the coating compound, the scratching-resistant waterproof coating compound is high in adhesiveness, strength, hardness and water resistance after film formation.
Description
Technical field
The application relates to a kind of scratch-resistant waterproof paint composition and preparation method thereof.
