Description

一种钢结构表面防冻防腐涂料及其制备方法
技术领域
本发明涉及机械材料领域,具体是一种钢结构表面防冻防腐涂料及其制备方法。
背景技术
钢材表面在与环境中的腐蚀介质接触时会发生化学或电化学反应而锈蚀,使钢材的性能发生退化,甚至破坏,因此钢结构的防腐技术对于钢结构的安全性能和耐久性起着极为重要的作用。实际工程中有很多钢构件的破坏就是由腐蚀而引起的。钢结构的防腐方法一般有两种:一是改变钢材的组织结构,在钢材冶炼过程中加入铜、镍、铬、锡等元素,提高钢材的抗腐蚀能力,这种方法造价较高,例如不锈钢;二是在钢材表面覆盖各种保护层,把钢材与腐蚀介质隔离,此种方法造价较低,效果较好,应用范围广。但是现有的用于钢材表面的防腐涂料在环境较为恶劣的环境下,其防腐能力大大降低,而且无法在低温下继续发挥作用,无法耐寒,保温效果差,导致钢材的腐蚀率大大加快,给钢结构带来极大的危险。
发明内容
本发明的目的在于提供一种钢结构表面防冻防腐涂料及其制备方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
一种钢结构表面防冻防腐涂料,由以下重量份的原料制备而成:氯乙烯改性聚丙稀酸乳液32~40份,二氧化硅12~14份,滑石粉6~8份,硅酸铝纤维11~13份,氧化铁10~12份,五氧化二钒11~13份,氧化锆4~6份,钛酸丁酯18~22份,氨基树脂24~30份,有机硅丙烯酸树脂40~44份,酚醛环氧树脂36~40份,聚醚多元醇二缩水甘油醚16~18份,去离子水60~80份。
作为本发明进一步的方案:具体由以下重量份的原料制备而成:氯乙烯改性聚丙稀酸乳液36份,二氧化硅13份,滑石粉7份,硅酸铝纤维12份,氧化铁11份,五氧化二钒12份,氧化锆5份,钛酸丁酯20份,氨基树脂27份,有机硅丙烯酸树脂42份,酚醛环氧树脂38份,聚醚多元醇二缩水甘油醚17份,去离子水70份。
一种所述的钢结构表面防冻防腐涂料的制备方法,具体步骤如下:(1)按配比称取上述各原料,备用;(2)将二氧化硅、滑石粉、硅酸铝纤维、氧化铁、五氧化二钒和氧化锆分别进行球磨5~6h,然后混合均匀;(3)将氯乙烯改性聚丙稀酸乳液、钛酸丁酯、氨基树脂、有机硅丙烯酸树脂、酚醛环氧树脂、聚醚多元醇二缩水甘油醚在36~40℃下混合,并搅拌12~16h,得混合液;(4)将混合粉加入去离子水中,在超声波中高速搅拌30~40min,然后加入混合液,继续高速搅拌15~17h,冷却至常温即可。
与现有技术相比,本发明的有益效果是:本发明涂料的附着力强,能有效附着在钢结构的表面,具有很好的防腐蚀、防水以及保温的特点,在恶劣的环境下能有效保护内部的钢不被腐蚀。
