一种耐洗碗机的水溶性涂料及其制备方法
摘要：
本发明公开了一种耐洗碗机的水溶性涂料，包括以下质量份的原料：水性环氧改性型有机硅树脂15‑35份，水性聚酯改性型丙烯酸树脂15‑35份，部分甲醚化三聚氰胺树脂6‑12份，改性型硅烷偶联剂1‑3份，乙二醇单丁醚8‑15份，异丁醇8‑15份，pH调节剂2‑5份，预分散颜料3‑8份，去离子水10‑30份，并经过制备工艺制成成品。采用以上方案，得到的水溶性涂料具有极好的耐水煮性及耐酸碱性，大大提高水性涂料的适用范围；将得到的涂料经160‑180℃烘烤25‑30min后，耐洗碗机清洗及烘烤的次数可达200次以上，并且该种水溶性涂料适用于玻璃、陶瓷等难附着的底材。
摘要（英）：

The invention discloses a water-soluble coating resisting a dish washing machine. The water-soluble coating is prepared from, by mass, 5-40 parts of waterborne epoxy modified organic silicon resin, 5-40 parts of waterborne polyester-modified acrylic resin, 3-15 parts of partially methyl-etherification melamine resin, 0.5-3 parts of a modified silane coupling agent, 5-15 parts of ethylene glycol butyl ether, 1-15 parts of isobutanol, 0.5-8 parts of a PH regulating agent, 1-10 parts of predispersed pigments and 5-30 parts of deionized water, and the finished product is prepared through the preparation process. By adopting the scheme, the obtained water-soluble coating has the excellent boiling resistance and acid and alkali resistance, and the application range of the water-soluble coating is greatly widened; after the obtained coating is baked for 25-30 min at the temperature of 160 DEG C to 180 DEG C, the dish washing machine resisting cleaning and baking frequency can reach 200 times or above, and the water-soluble coating is suitable for substrates such as glass and ceramic which are difficult to adhere.
