Hydrophobic and oleophobic polymer film material and preparation method thereof

The invention provides a hydrophobic and oleophobic polymer film material and a preparation method thereof, the polymer film material is prepared from the following raw materials by weight: 1-10 parts of hydroxyl-terminated hyperbranched polyester, 1-2 parts of PAMAM, 4-15 parts of a curing agent, 1-2 parts of an antifouling agent, 5-15 parts of propylene glycol methyl ether acetate, 2-8 parts of an organic solvent, and 0.01-0.02 part of a catalyst; and the curing agent is isocyanate propyl triethoxy silane or 3-(methacryloyloxy) propyl trimethoxy silane. IPTS/G-570 is used as a curing agent, enough alcoholic hydroxyl group crosslinking sites are provided by HBPE, IPTS/G-570 is selected as the curing agent to form heavy crosslinking with HBPE, and all the reagents are mixed to form a uniform coating solution. The coating material can be still in a flowing liquid state after being kept for 3 days, and construction is convenient. 本发明提供一种疏水疏油高分子薄膜材料及其制备方法，该高分子薄膜材料，是由以下重量份的原料制成：端羟基超支化聚酯1～10份、PAMAM1～2份、固化剂4～15份、防污
