一种用于汽车轮毂漆的聚酯改性羟基丙烯酸树脂及其合成方法
摘要：
本发明公开了一种用于汽车轮毂漆的聚酯改性羟基丙烯酸树脂及其合成方法，它由甲基丙烯酸甲酯15~30份、甲基丙烯酸羟乙酯3~10份、丙烯酸异辛酯5~10份、丙烯酸丁酯1~5份、聚酯预聚物5~15份、有机溶剂40~60份和引发剂0.3~0.6份制成。本发明提供的聚酯改性羟基丙烯酸树脂制得的漆膜具有常温下耐腐蚀性好，硬度高，抗冲击性好，附着力强，柔韧性好等优点，可广泛使用于轮毂漆领域。
摘要（英）：

The invention discloses a polyester modified hydroxyl acrylic resin for automobile hub paint and a synthetic method thereof. The polyester modified hydroxyl acrylic resin for automobile hub paint is prepared from, by weight part, 15-30 parts of methyl methacrylate, 3-10 parts of hydroxyethyl methylacrylate, 5-10 parts of 2-ethylhexyl acrylate, 1-5 parts of butyl acrylate, 5-15 parts of polyester prepolymer, 40-60 parts of organic solvent and 0.3-0.6 part of initiator. A paint film prepared from the polyester modified hydroxyl acrylic resin for the automobile hub paint has the advantages of being good in corrosion resistance at normal temperature, high in hardness and impact resistance, good in adhesive force and flexibility and the like and accordingly can be applied to the field of hub paint.
