Description

一种低成本水性双组份喷胶及其制备方法
技术领域
本发明涉及胶粘剂技术领域，特别是涉及一种低成本水性双组份喷胶及其制备方法。
背景技术
喷胶是一种具有合适的粘度，适合于喷枪作为施工工具喷涂施工，将两种不同的物质界面紧密连接起来，起到传递应力作用的胶粘剂，广泛用于家具、皮革和装饰行业等。传统油性喷胶使用大量有机溶剂，不仅对环境造成严重危害，而且对工人和用户的身体造成损伤，远不能满足当前对环保和健康的需求，因此，以水为溶剂的水性喷胶逐渐获得市场的认可。目前水性喷胶基本以氯丁树脂为主，如公开号为CN 102212320 B、CN 101560367B、CN 103865439 A的专利公开的水性喷胶，水性氯丁树脂具有起粘快、持粘强等优点，用于水性喷胶具有较好的使用效果。然而，国产氯丁胶乳存在不稳定、粒径粗等问题，使用效果较好的水性氯丁树脂基本为进口产品，制得的水性喷胶相比油性喷胶价格昂贵，在推广过程中存在很大障碍。
其余水性喷胶如，公开号为CN 106753086 A的专利公开的水性喷胶，该水性喷胶由天然胶乳配合丙烯酸酯乳液制得，在配置过程中需要加入氨水，氨水易挥发且具有刺鼻味道，而且天然胶乳搭配丙烯酸酯乳液等也无法满足海绵捏边等对喷胶具有较高要求的操作。公开号为CN 106753086 A的专利公开的双组份喷胶中，A组分水性聚氨酯以脂肪族异氰酸酯配合含双键的聚酯多元醇制成，所用原材料成本高，B组分用量占A组分50%-100%，配合使用时严重降低了有效成分的比例，客户喷胶量高，进一步提高了使用成本。
发明内容
本发明的目的在于克服现有技术的不足，提供一种低成本水性双组份喷胶及其制备方法，本发明采用固化剂使得水性树脂快速成膜，提升树脂的冷贴即粘性能，同时水性聚氨酯与丙烯酸酯性能互补，改善水性喷胶的低温粘性和耐热性。
