一种复合聚酯热熔胶、制备方法及抗冲刷土工布的制备方法
技术领域
本发明涉及聚酯类热熔胶制备技术领域，具体涉及一种复合聚酯热熔胶、制备方法及抗冲刷土工布的制备方法。
背景技术
由于土工布具有质量轻、柔性好、强度高、整体性强且不易腐烂的优点，在工程中具有反滤、排水、隔离、增强和防渗等作用，可提高工程质量，因此广泛应用于水利、水运、公路、建筑等工程领域。
其中聚酯类热熔胶常常被用于土工布的粘合加工，其制备方法主要是包括直接酯化缩聚法和酯交换缩聚法，其中酯交换缩聚法合成过程中会生成低分子量有毒物质对环境造成污染，因此在应用上存在一定限制。而现有的通过直接酯化缩聚法得到的聚酯类热熔胶，普遍存在粘接强度低、固化速度慢、抗冲刷性能差的问题。
此外，目前我国水利工程使用的土工布存在抗冲刷强度低、保土性能差防护能力差、使用寿命短的问题，已经无法满足人们对土工布的高要求。
发明内容
本发明的目的是提供一种复合聚酯热熔胶、制备方法及抗冲刷土工布的制备方法，以解决现有聚酯类热熔胶普遍存在粘接强度低、固化速度慢、抗冲刷性能差的问题以及土工布存在抗冲刷强度低、保土性能差、防护能力差、使用寿命短的问题。
本发明解决上述技术问题的技术方案如下：

(3)在常压且氮气保护下，向聚酯热熔胶中加聚甲基丙烯酸甲酯微球在温度在230℃～240℃混合搅拌1h-1.5h，得到复合聚酯热熔胶。
进一步地，在本发明较佳的实施例中，上述步骤(1)中钛/钴复合催化剂由钴系催化剂与钛系催化剂复合，硅系催化剂为醋酸钴，钛系催化剂包括钛酸四丁酯、钛酸四异丙酯或钛酸四甲酯；钛/钴复合催化剂加入量为二元酸总质量的0.01％～0.03％，且钛系催化剂占钛/钴复合催化剂的65-75wt％，其余量为钴系催化剂。
进一步地，在本发明较佳的实施例中，上述步骤(2)中稳定剂为亚磷酸三苯酯或磷酸三甲酯。

进一步地，在本发明较佳的实施例中，上述复合聚酯热熔胶和水加入量的质量比为3-4：1。
本发明具有以下有益效果：
1、本发明采用具有直链结构的2-苯基戊二酸和二乙烯己二醇对聚酯热熔胶进行改性，能有效提高聚酯热熔胶的粘结强度，同时还可以降低聚酯高分子链的刚性，改善其柔顺性，从而降低其玻璃化转变温度，从而提高其固化速度。

3、本发明采用由钴系催化剂与钛系催化剂复合的钛/钴复合催化剂，钛系催化剂为主催化剂用于加快酯化放应进程，钴系催化剂为助催化剂用于防止聚酯分解产生其他物质降低主催化剂的催化活性。
4、本发明的复合聚酯热熔胶中还添加了葡萄糖酸内酯作为促进剂，促进聚甲基丙烯酸甲酯微球和聚酯热熔胶的共混进程，同时还能提高复合聚酯热熔胶的粘结强度和固化速度。
5、本发明采用聚对苯二甲酸乙二醇脂编织布和聚丙烯土工布均具有耐高温、不吸水性、耐冲击性和无毒性的优点，并通过复合聚酯热熔胶相粘合，得到高抗冲刷强度高、保土性能好、防护能力强、使用寿命长的的抗冲刷土工布。
