Description

环保低碳自转锈涂料及其制备方法 技术领域
本发明涉及水性涂料领域，特别是涉及一种用于钢结构产品上环保低碳自转锈涂料及其制备方法。
背景技术
目前用于钢结构产品上的涂料主要采用有机溶剂型涂料，有机溶剂型涂料中含有大量挥发性有机化合物(简称VOC)，大多数VOC为易燃、易爆的有毒物质，其中包含有多种致癌物质，它会伤害人的肝脏、肾脏、大脑、神经系统，刺激眼睛和呼吸道，使皮肤过敏，使人产生头痛、咽痛与乏力，对人类生态环境造成了严重影响。随着各国环保法规对挥发性有机化合物的限制，目前涂料的研究主要向着绿色环保型涂料方向发展。作为环境友好型涂料的水性涂料，其中含有的挥发性有机物的含量非常低，因而钢结构产品的涂装将朝着环保的水性涂料方向发展，但是目前市场上常见的水性涂料涂装后形成的涂层还无法达到溶剂型涂料涂装后形成的涂层的性能要求，无法满足使用要求。
另外，在涂装过程中，由于钢结构产品属于易锈蚀产品，因而在对钢结构产品涂装前需对锈蚀的钢结构产品进行抛丸或喷砂等除锈处理，而后再对钢结构产品进行涂装，抛丸或喷砂处理会产生粉尘污染，施工环境十分恶劣，此外受施工条件限制，除锈后的钢结构产品如若不能及时涂装，则易出现二次生锈问题，这样就需再次对生锈的钢结构产品进行除锈处理，大大增加了施工人员的工作量，成本及能耗均较高。
