Description

水性超薄型钢结构防火涂料
技术领域
本发明涉及涂料领域，具体涉及一种水性超薄型钢结构防火涂料。
背景技术
随着我国经济建设的飞速发展，钢结构建筑大量出现在公共建筑、商业建筑等高层建筑及工业产房中。钢材具有良好的抗拉强度，但是随着温度的升高，特别是在温度达到400-600℃时，其强度几乎成直线下降，当温度达到600℃以上时，钢材几乎失去了承载能力。因此，对钢结构采取有效的保护措施，使其能在意外发生时免受高温火焰的直接灼烧，延缓塌陷时间，为消防救援提供宝贵的时间就显得十分重要。目前，世界各国对钢结构采用了多种方法进行防火保护，主要有在钢结构表面粘贴无机防火板、喷涂无机纤维板、粘帖纤维板、粘帖柔性板材及结构内部通水，但是往往施工比较复杂，成本较高，同时会影响美观。而目前通用的防火涂料往往需要涂层厚度达到5mm以上才能达到较好的防火效果，需要进行多次重复喷涂，费工费料。
发明内容
本发明的目的是提供一种水性超薄型钢结构防火涂料，可提高钢结构的耐火极限，涂层2毫米就能达到耐火2小时，施工方便，成本较低。
为了实现本发明的目的，采用以下技术方案：
水性超薄型钢结构防火涂料，其特征在于，包括以下重量百分比的原料：聚磷酸铵25％-30％、三聚氰胺6％-10％、季戊四醇8％-11％、钛白粉7％-9％、硼酸锌5％-6％、滑石粉2％-3％、丙烯酸树脂20％-22％、余量水。
进一步地，所述聚磷酸铵的聚合度为2000。
进一步地，所述季戊四醇的纯度≥99.8％。
本发明还提供了所述水性超薄型钢结构防火涂料的制备方法，其特征在于，包括以下步骤：
依次称取上述重量百分比的原料，将其加入球磨机内；球磨至少15小时，同时调节粘度，测试细度；粘度为300±50S，细度≤100um时放料，即得防火涂料。
本发明的有益效果为：该涂料在普通防火涂料的基础上进行改进，加入的丙烯酸树脂使丙烯酸增大成碳剂，遇火产生，增加碳化层强度，耐高温火焰冲击，提高钢结构的耐火极限，涂层2毫米就能达到耐火2小时，施工方便，成本较低。
本发明可应用于机场、电厂、石化、体育场、商业广场、工业厂房、高层建筑等室内裸露钢结构的防火保护。该涂料受火烧时能膨胀发泡并形成致密的隔热层，从而延缓钢材的升温，可提高钢结构的耐火极限，耐火极限可达2小时。与普通的钢结构涂料相比，该涂料粒度更细、涂层更薄、施工方便、装饰性好，具有优越的黏结强度和装饰效果，既可满足防火要求，又能满足人们对装饰性的需要。
具体实施方式
下面结合实施例对本发明作进一步阐述，但这并不是对本发明权利要求的限制。

实施例2：
一种水性超薄型钢结构防火涂料，包括以下重量百分比的原料：聚合度为2000的聚磷酸铵26％、三聚氰胺8％、纯度为99.8％的季戊四醇9％、钛白粉8％、硼酸锌6％、滑石粉3％、丙烯酸树脂20％、水20％。依次称取上述重量百分比的原料，将其加入球磨机内；球磨17小时，同时调节粘度，测试细度；粘度为300±50S，细度≤100um时放料，即得防火涂料。
