Description
技术领域
本发明属于建筑材料领域，具体涉及防水渗透涂料、含有该涂料的硅酸钙板及其制备方法。
背景技术
硅酸钙板是以无机矿物纤维或纤维素纤维等松散短纤维为增强材料，以硅质-钙质材料为主体胶结材料，经制浆、成型、在高温高压饱和蒸汽中加速固化反应，形成硅酸钙胶凝体而制成的板材。是一种具有优良性能的新型建筑和工业用板材，其产品防火，防潮，隔音，防虫蛀，耐久性较好，是吊顶，隔断的理想装饰板材。
硅酸钙板因为在外墙应用易吸水而鼓泡脱层，所以在涂装前必须进行基层防水封闭处理。现有的方法有两种：用溶剂型UV涂料辊涂；用环氧树脂加有机溶剂如甲苯、醋酸丁酯稀释后再加入酚醛胺类固化剂搅匀后辊涂。以上两种方法都是用油性溶剂型涂料，有机溶剂如甲苯、醋酸丁酯类使用量大，生产车间气味浓烈，即危险又不环保，其中UV涂料渗透力有限，即使渗透进板材里也因为光照不到而无法固化，达不到防水封闭效果很难保证。而环氧树脂操作不便，涂层厚薄不一，涂层太薄，防水封闭效果差，辊涂厚，又影响层间附着。薄厚在辊涂生产线上很难掌握，急需新的产品与工艺方法来改进提高。
发明内容
针对以上技术问题，本发明的目的是提供防水渗透涂料、含有该涂料的硅酸钙板及其制备方法，制备的涂料无毒无味，对环境和人体无害，施用后碳酸钙板更耐刷洗、耐高低温，防水性更强。
为了实现上述目的，本发明采用如下技术方案：
首先，本发明提供一种防水渗透涂料，包括以质量百分比计的以下成分：甲基硅酸钾35-43％，余量为纯净水，将所述甲基硅酸钾和纯净水加热搅拌，溶解完全即得所述防水渗透涂料。
进一步地，甲基硅酸钾40％，余量为纯净水，将所述甲基硅酸钾和纯净水加热搅拌，溶解完全即得所述防水渗透涂料。
其次，本发明提供上述含有防水渗透涂料的硅酸钙板的制备方法，包括以下步骤：
(1)按质量百分比将所述甲基硅酸钾和所述纯净水混合，一边加热，一边搅拌，直到溶解完全得到所述防水渗透涂料；
(2)将硅酸钙板用砂纸砂平，除浮尘，将所述防水渗透涂料辊涂到硅酸钙板表层直至饱和渗透，待干后即得所述含有防水渗透涂料的硅酸钙板。
进一步地，所述步骤(1)中加热温度为55-65度。
进一步地，所述步骤(2)中将硅酸钙板用平120目砂纸砂平。
进一步地，所述步骤(2)中待干12小时即得所述含有防水渗透涂料的硅酸钙板的。
本发明还保护一种含有防水渗透涂料的硅酸钙板。
与现有技术相比，本发明具有如下有益效果：无毒无味，对环境和人体无伤害；工艺施工简单效果持久，耐刷洗，耐高低温度；防水性好、吸水率减少到8％。
