背景技术
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38～47份、滑石粉4～8份、纳米氧化铝8～11份、纳米氧化钛1～4份、氯化铬2～5份、硅烷偶联剂2～6份、陶瓷空心微珠6～9份、丁二醇11～17份、聚酰胺树脂21～28份、羟甲基纤维素14～19份、纳米二氧化硅9～14份、磷酸三丁酯6～13份、甲醇11～19份、膨润土10～17份、聚四氟乙烯8～16份、炭黑6～11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。
本发明与现有技术相比，具有如下的优点和有益效果：
1、本发明用于高温环境的防腐蚀涂料，本发明的涂料适用于高温环境中，并且在高温下也不会影响本发明涂料的性能，使用寿命更长；
2、本发明用于高温环境的防腐蚀涂料，本发明具有较好的防腐蚀效果，更便于使用；
