摘　　要：主要探讨了高温烘烤对有机硅改性丙烯酸树脂涂膜应用性能的影响,并进行了评估。试验结果表明,采用不同的硅胶修饰剂,其对丙烯酸酯类树脂涂层的抗老化能力有一定的影响。以乙烯基硅氧烷、甲基三氯硅烷、聚乙烯基硅氧烷、聚二甲基硅氧烷为主要原料,采用多种硅氧烷对水溶性硅氧烷进行改性,并系统表征硅氧烷对水溶性硅氧烷的影响。研究表明,该体系在较高温度下具有较好的耐焙烧能力,其耐焙烧能力的表现由低到高依次为:乙烯基硅氧烷、甲基三氯硅烷、聚乙烯基硅氧烷、聚二甲基硅氧烷。In this paper,the effect of high temperature baking on the application performance of silicone modified acrylic resin coating was discussed and evaluated.The experimental results show that different silicone modifiers have a certain effect on the anti-aging ability of acrylate resin coatings.Water-soluble siloxanes were modified with vinylsiloxanes,methyltrichlorosilanes,polyethylenylsiloxanes and polydimethylsiloxanes as the main raw materials,and the effects of siloxanes on water-soluble siloxanes were systematically characterized.The results show that the roasting resistance of the system is as follows:vinylsilicane、trichloromethylsilicane、polyvinyl siloxane、polydimethylsiloxane.
