Description

一种高粘度且粘温特性局部敏感的聚酯热熔胶的制备方法 技术领域
本发明涉及一种聚酯热熔胶的制备方法，具体涉及一种低熔点、高粘度且在特定温度范围内粘度大幅下降的聚酯热熔胶的制备方法。
背景技术
低粘度聚酯通过二次加工制备相应的高粘度聚酯，其制备工艺繁琐，如中国专利CN1317030A先生产低粘度聚酯与噁唑啉组成母料，再与高粘度聚酯混合，进行下一步加工，其工艺繁多，且噁唑啉对生物及环境有一定的危害。为了克服现有技术的不足，本专利提供了一种熔点为130℃～135℃，粘度为700～750Pa.s(160℃)的低熔点高粘度且粘温特性局部敏感的聚酯热熔胶的制备方法。
发明内容
本发明提供了一种高粘度且粘温特性局部敏感的聚酯热熔胶的制备方法，包括以下步骤：
(1)将二元酸和二元醇及催化剂钛酸四丁酯按一定比例加入酯化釜中进行酯化反应，反应温度为140℃～200℃，当酯化反应馏出水的量为理论出水量的93％以上时，酯化反应结束；
(2)将抗氧剂加入步骤(1)的产物中，在240～245℃、50～80Pa的条件下进行减压缩聚反应1.0小时，即可获得高粘度且粘温特性局部敏感的聚酯热熔胶，从160℃升温至170℃时，其粘度下降幅度为75％～80％；
所述二元酸为对苯二甲酸、间苯二甲酸、丁二酸、十二二酸和己二酸的混合物；
所述二元醇为丁二醇、二丙二醇和己二醇的混合物；
所述二元酸和二元醇的摩尔数之比为1:1.50；
所述的对苯二甲酸和间苯二甲酸的摩尔比为1:0.10～0.15；
所述的对苯二甲酸和丁二酸的摩尔比为1:0.20～0.30；
所述的对苯二甲酸和十二二酸的摩尔比为1:0.1～0.25；
所述的对苯二甲酸和己二酸的摩尔比为1:0.40～0.50；
所述的丁二醇和二丙二醇的摩尔比为1:0.20～0.60；
所述的丁二醇和己二醇的摩尔比为1:0.30～0.70；
所述的抗氧剂选自磷酸三甲酯、抗氧剂168、抗氧剂1010中的一种；
所述催化剂钛酸四丁酯的质量为二元酸总质量的0.03～0.06％；
所述抗氧剂的质量为二元酸总质量的0.5～0.8％。
本发明的创新之处在于通过特定的原料配方设计及简单的聚酯工艺，合成出一种熔点为130～135℃，高粘度且粘温特性局部敏感的聚酯热熔胶。
性能测试：以下实施例和对比例中各产品的性能测试标准分别为：熔点测试参照国际标准ISO 11357，粘度测试参照国家标准GB/T 7193.1-1987。
本专利所制备的聚酯热熔胶在170℃及以上的温度涂胶，具有较好的流动性及流平性。在冷却的过程中，温度降至160℃时，其粘度瞬间增大，被粘物之间的粘接力也瞬间增大，更加有效的粘接在一起，也可有效的防止由于各种外力作用，被粘物之间移位。本专利所制备的聚酯热熔胶可直接应用或制成热熔胶膜应用于服装、鞋材、烫画、商标、地毯、木材等领域的粘合。
