The invention discloses a stain-resistant resin as well as a preparation method and application thereof, and belongs to the field of synthetic resin. The stain-resistant resin comprises the following components in parts by weight: 30-43 parts of epoxy resin, 12-19.5 parts of methacrylic acid, 2-6.5 parts of a chain extender and 5-15 parts of glycidyl ester containing tertiary carbon groups. Epoxy resin and methacrylic acid are polymerized to obtain an epoxy acrylate prepolymer with side hydroxyl and terminal carboxyl, then the epoxy acrylate prepolymer further reacts with a chain extender for chain extension, glycidyl ester containing tertiary carbon groups is used for end capping, non-polar tertiary carbon groups are introduced into molecular chains, the surface tension of the resin is increased, and the surface of a product is not prone to being infiltrated by pollutants. An artificial quartz stone product containing the stain-resistant resin disclosed by the invention has better stain resistance, is convenient to clean, and can enlarge the application range of the product.
本发明公开了一种耐污树脂及其制备方法与应用，属于合成树脂领域。所述耐污树脂包含如下重量份的成分：环氧树脂30～43份、甲基丙烯酸12～19.5份、扩链剂2～6.5份和含叔碳基缩水甘油酯5～15份。环氧树脂与甲基丙烯酸聚合可得到带侧羟基和端羧基的环氧丙烯酸酯预聚物，再与扩链剂进一步反应扩链，用含叔碳基缩水甘油酯进行封端，把非极性的叔碳基团引入分子链，增加树脂的表面张力，使得制品表面不容易被污染物浸润。本发明公开的包含所述耐污树脂的人造石英石制品具有较好的耐污性，便于清洁，可增大产品的使用范围。
