Description

technical field [0001] The invention relates to the technical field of inorganic coatings, more specifically, it relates to an inorganic anti-graffiti environmental protection coating and a preparation method thereof. Background technique [0002] Insufficient stain resistance of coatings is a common problem common to exterior wall coatings. It is also an outstanding technical problem restricting the popularization and application of exterior wall coatings in my country. Fluorocarbon resins with low surface energy, silicone-modified acrylic resins or additives containing fluorine and silicon are commonly used at home and abroad to reduce the adhesion of pollutants, thereby improving the stain resistance of coatings. [0003] At present, the Chinese invention patent with application number CN2006100291638 discloses a preparation method of self-cleaning fluorocarbon resin coating. The main preparation steps include: first react diisocyanate and trihydric alcohol to a certain...
