CN104962146A 一种高阻氧自粘性聚乙烯醇涂料及其制备方法 无效 - 驳回

一种高阻氧自粘性聚乙烯醇涂料及其制备方法
摘要：
本发明提供一种高阻氧自粘性改性聚乙烯醇涂料，该涂料是由含有下述重量含量的原料配制成：10.4～15％聚乙烯醇、0.3～0.8％N-甲基烯丙基胺、1.2～1.5％环氧树脂、0.008～0.03％催化剂、0.001～0.004％消泡剂、83～88％去离子水。该涂料集高阻氧性能和自粘性于一体，用于涂布工艺无需涂底胶即可直接涂布于基材上，在很大程度上节约了成本，而且保证了涂布工艺的环保性。
摘要（英）：

The invention provides a high-oxygen-barrier self-adhesive polyvinyl alcohol coating. The coating is prepared by using the following raw materials in content by weight: 10.4-15 percent of polyvinyl alcohol, 0.3-0.8 percent of N-methylallylamine, 1.2-1.5 percent of epoxy resin, 0.008-0.03 percent of catalyst, 0.001-0.004 percent of defoaming agent and 83-88 percent of deionized water. The coating is integrated with high-oxygen-barrier performance and self-adhesiveness and can be directly coated on a substrate by using a coating process without coating primer, the cost is reduced to a very great extent and the environmental friendliness of the coating process is guaranteed.
