一种氟-磷酸酯改性水性醇酸树脂及其制备方法
摘要：
本发明涉及一种氟‑磷酸酯改性水性醇酸树脂，由植物油、有机酸酐、多元酸、多元醇、二羟甲基丙酸、烷基丙烯酸酯磷酸酯、氟烯类单体、苯甲酸和中和剂通过反应制得；本发明提供一种氟‑磷酸酯改性水性醇酸树脂的制备方法。本发明制得的氟‑磷酸酯改性水性醇酸树脂，其数均分子量为10000～20000，粒径为400～600nm，玻璃化温度Tg为25～45℃；本发明制得的氟‑磷酸酯改性水性醇酸树脂，其分子结构中含有氟原子和磷酸酯功能基团，具有优良的附着力、疏水性、耐化学品性、耐油性、耐老化性、耐腐蚀性、耐盐雾性；广泛用于水性防腐涂料、水性钢构涂料、水性机械涂料、水性木器涂料、水性塑胶涂料等。
摘要（英）：

The invention relates to a fluorine-phosphate modified waterborne alkyd resin. The fluorine-phosphate modified waterborne alkyd resin is obtained through the reaction of vegetable oil, organic acid anhydride, polybasic acid, polyhydric alcohols, dimethylolpropionic acid, alkyl acrylate phosphate, fluoroolefin monomer, benzoic acid and a neutralizing agent; the invention provides a preparation method of the fluorine-phosphate modified waterborne alkyd resin. The number-average molecular weight range is 10,000-20,000, the particle size range is 400-600nm and the glass transition temperature Tg range is 25-45 DEG C; the molecular structure of the fluorine-phosphate modified waterborne alkyd resin comprises fluorine atoms and phosphate ester functional groups and has excellent adhesive force,hydrophobicity, chemical resistance, oil resistance, aging resistance, corrosion resistance and salt fog resistance; the fluorine-phosphate modified waterborne alkyd resin can be widely used for waterborne anticorrosive coatings, waterborne steel structure coatings, waterborne mechanical coatings, waterborne wood coatings, waterborne plastic coatings and the like.
