The invention belongs to the field of polymer coatings, and provides a cigarette holder profile outer packaging coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: a fluorine-modified octavinyl polyhedral oligomer 5-40 parts of silsesquioxane, 40-70 parts of modified polyurethane, and 0.5-2.0 parts of 2-hydroxy-2-methylacetophenone. The cigarette holder profiled outer packaging coating of the invention has excellent heat resistance, super-hydrophobicity, chemical stability and fluidity, and the molding process adopts the UV curing method, the curing rate is fast, and the quality stability of the packaging coating is effectively improved. and production efficiency, and at the same time, it can effectively improve the isolation effect of the filter part on the sidestream smoke. |
