Description

一种防龟裂的环氧陶瓷涂料及其制备方法
技术领域
本发明涉及防腐涂料领域，具体涉及一种防龟裂的环氧陶瓷涂料及其制备方法。
背景技术
球墨铸铁管以强度高、韧性好、可靠性高、耐腐蚀性能好等优点正逐步取代灰铁管，近年来，随着城市化规模不断扩大，对管材的需求特别是大口径管材的需求不断增加，在国内以及国际各大城市供水管道和管网改造中发挥越来越大的作用，作为这些项目工程的首选材料，被广泛应用于城建输水、输气等工程上，为球墨铸铁管行业提供了巨大的市场。
环氧树脂陶瓷是铸铁管内衬的一种新型防腐涂层，它是将环氧陶瓷涂料以机械喷涂或手工刷涂，自然固化在铸铁管内衬水泥内壁上，最终得到致密光滑、坚如陶瓷、粘结牢固、厚度均匀，耐水、防腐蚀、电绝缘性能优异的内衬层，适用于输送污水、中水、饮用水的供排水工程。内衬环氧树脂陶瓷铸铁管耐水、耐稀酸、耐盐、耐碱性好，涂层光滑、致密，可长期与混凝土表面牢固结合，并耐海洋生物和微生物腐蚀，是混凝土表面首选的防渗防腐涂层，寿命可达20年以上。
作者叶秀芳等人在《新型陶瓷改性环氧树脂涂料的制备及性能表征》一文中，利用甘氨酸改性环氧树脂，制备了水性环氧乳液，所制得的水性环氧乳液与陶瓷粉混合，在固化剂的作用下，得到了环氧树脂陶瓷涂料。该涂层虽然具有较好的涂膜性能，涂层可在室温下固化，使用方便；但是涂层耐腐蚀性能差。

（2）将十二碳醇酯、磷酸三苯酯、二乙二醇丁醚加入到分散罐中，以800-1000转/min的搅拌速率搅拌至均匀；将步骤（1）的产物、膨胀蛭石、纳米二氧化硅、硫酸钡加入到分散灌中，以1500-1800转/min的搅拌速率高速搅拌40-50min，加入三（十二烷基苯磺酰基）钛酸异丙酯、苯丙乳液和相当于苯丙乳液重量份4-5倍的去离子水，继续高速搅拌1.5-2h，搅拌制成浆料；加入碳纤维，以1500-1800转/min的搅拌速率高速搅拌40-50min，使得碳纤维在浆料中分散均匀；
（3）将环氧树脂E-44、稀释剂660A混合搅拌均匀，水浴加热至70-80℃搅拌3-4h，取出，冷却，加入三缩水甘油基对氨基苯酚、双环己酮草酰二腙，混合搅拌均匀后加入步骤（2）的产物中，再加入水玻璃，以1800-2000转/min的搅拌速率高速搅拌40-50min，再加入羟丙基甲基纤维素，继续高速搅拌1-2h，得到防龟裂的环氧陶瓷涂料。
