| 目的 提高丙烯酸氨基烤漆的耐DOT4制动液性能，并保留其良好的耐冲击性能。方法 通过制备高酸价的丙烯酸树脂并与一定量的高分子量的环氧树脂（E20）共混改性后，与氨基树脂混合加热固化制备涂层，分别采用DOT4制动液高温浸泡法、划格法和冲击试验测涂层的耐制动液、附着力和耐冲击性能。结果 成功制备了酸价为60 mgKOH/g与固含量为60%高酸价丙烯酸树脂。当高酸价丙烯酸树脂以质量比为3:1的比例与氨基树脂混合并加入4%的E20时制备的涂层具有优异的综合性能，涂层的附着力为0级，耐冲击性能为50 kg•cm，在100 ℃的DOT4制动液中浸泡7 h后，涂层不脱落，不起泡。结论 该方法适用于提高丙烯酸氨基烤漆的耐DOT4制动液性能。 |

| Objective To improve the DOT4 braking-oil-resistance of polyacrylate/amino resin coating and retain its good shock resistance. Methods Polyacrylate resin with high acid value was synthesized with high molecular weight epoxy resin (E20) to prepare polyacrylate/amino resin coating by mixing, heating and curing with the polyacrylate resin. The braking-oil-resistance, adhesive force and shock resistance of the polyacrylate/amino resin coating were tested with high temperature soaking method, grid test and shock test of DOT4. Results The polyacrylate resin with acid value of 60 mgKOH/g and solid content of 60% was synthesized successfully. When the ratio of polyacrylate resin to the amino resin equaled to 3:1 and the concentration of E20 equaled to 4% based on the sum of the mass polyacrylate resin and amino resin, the coating had the best combination property with adhesive force of 0 grade and shock resistance of 50 kg•cm. The coating could stand baking in DOT4 at 100 ℃ for 7 h without exfoliating or blistering. Conclusion This method is suitable for improving DOT4 brake fluid resistance of acrylic amino paint. |
