随着工业技术进步,金属材料的使用越来越广泛,金属及其构件的腐蚀问题已遍及国民经济的各个领域,给人类社会造成了巨大损失。涂料防腐以其施工简便、经济适用、不受设备面积、形状的约束等特点而被广泛的应用。目前的涂料,其防腐性、耐热性差,有的会有不同程度的毒副作用及刺激气味,有害人体健康。近些年,随着科学技术的发展,对涂料的技术要求越来越高,要求在高温下漆膜不变色、不脱落、仍能保持良好的物理机械性能、隔热性能和防腐性能。
发明内容
本发明所要解决的技术问题是现有涂料在高温环境中性能较差,使用寿命效果变差,目的在于提供用于高温环境的防腐蚀涂料,解决在高温环境中涂料的使用的问题。
本发明通过下述技术方案实现:

用于高温环境的防腐蚀涂料,包括以下重量份数的组分:环氧改性有机硅树脂40~45份、滑石粉5~7份、纳米氧化铝9~11份、纳米氧化钛1~3份、氯化铬2~4份、硅烷偶联剂3~5份、陶瓷空心微珠7~9份、丁二醇12~15份、聚酰胺树脂23~27份、羟甲基纤维素15~18份、纳米二氧化硅10~13份、磷酸三丁酯7~12份、甲醇13~18份、膨润土12~16份、聚四氟乙烯10~15份、炭黑7~10份。
用于高温环境的防腐蚀涂料,包括以下重量份数的组分:环氧改性有机硅树脂43份、滑石粉6份、纳米氧化铝10份、纳米氧化钛2份、氯化铬3份、硅烷偶联剂4份、陶瓷空心微珠8份、丁二醇13份、聚酰胺树脂25份、羟甲基纤维素16份、纳米二氧化硅12份、磷酸三丁酯10份、甲醇15份、膨润土14份、聚四氟乙烯14份、炭黑9份。
本发明的制作方法为:将环氧改性有机硅树脂、滑石粉、丁二醇、聚酰胺树脂、羟甲基纤维素、磷酸三丁酯、膨润土、炭黑依次加入反应容器中混合,用搅拌机以搅拌速度1800~2300r/min的速度搅拌15~20min后,在170~210℃下保温半小时;将分散后的物料混合组分加入研磨机进行研磨,研磨至粒度为3~5um,再依次加入纳米氧化铝、纳米氧化钛、纳米二氧化硅、硅烷偶联剂、陶瓷空心微珠、氯化铬、甲醇、聚四氟乙烯,以搅拌速度为1000~1300r/min的速度搅拌分散25~35min至粒度为30~45um,即可得到成品。
在本发明中环氧改性有机硅树脂的作用是提高涂料的耐高温、防腐蚀、耐溶剂性、机械性能、耐真空紫外线辐照性能;在本发明中滑石粉也可以增强涂料形状的稳定性、机械性能、降低变形性,提高粒度均匀分散性。
纳米二氧化硅可以快速形成网状结构,提高漆膜的耐老化性能、漆膜强度、光洁度等。纳米材料形成致密的涂层可以提高抗渗性及防紫外线吸收、防热老化能力,能起到增加结合强度的作用。
