Preparation method of PVDC packaging ink

The invention relates to the field of printing ink, in particular to a preparation method of PVDC packaging ink. According to the method, PVC (polyvinyl chloride), modified styrene resin, color paste, a coloring agent, a wetting dispersant, a surfactant, an anti-sticking aid, an HDI (hexamethylene diisocyanate) curing agent, ethyl ester, n-propyl ester and propylene glycol methyl ether acetate are adopted to prepare the PVDC packaging ink. The PVDC packaging ink prepared by the invention has excellent anti-sticking performance, and an ink layer is not anti-sticking and does not fall off after being resistant to steaming and boiling. Therefore, the hidden danger that the printing ink is adhered and falls off after the PVDC packaged product in the existing market is cooked at high temperature is solved. 本发明涉及印刷油墨领域，具体关于一种PVDC包装用油墨的制备方法；本方法采用PVC、改性苯乙烯树脂、色浆、着色剂、湿润分散剂、表面活性剂、抗粘助剂、HDI固化剂、乙酯、正丙酯、丙二醇甲醚醋酸酯，来制备PVDC包装用油墨；本发明制备的PVDC包装用油墨，具有优异的抗反粘性能，耐蒸煮后墨层不反粘，不脱落。从而解决了现有市场上PVDC包装的产品在经高温蒸煮后油墨反粘脱落的隐患。
