Waterproof coating for humid roof environment, and preparation method thereof
The invention provides a waterproof coating for a humid roof environment, and a preparation method thereof. The waterproof coating is prepared by the following steps: adding a crystallization activator into water to prepare a solution, then adding nano-silicon dioxide aerogel to carry out saturated adsorption on the crystallization activator, then filtering and drying to obtain a silicon dioxide aerogel loaded activator, and then grinding and uniformly mixing the silicon dioxide aerogel loaded active agent, Portland cement, silica fume, quartz sand, a water reducing agent, a water retaining agent and redispersible latex powder to obtain the product. The waterproof coating uses the slow release effect of the silicon dioxide aerogel loaded activator on the crystallization active agent to prevent the early crystallization of the crystallization activator, so that the crystallization activator is slowly released and permeates into capillary pores of the concrete to generate insoluble crystals, and the capillary pores are blocked, thereby the concrete is more compact, and the concrete has better waterproof performance.
本发明提出一种用于屋顶潮湿环境的防水涂料及其制备方法，所述防水涂料是将结晶活性剂加入水中制成溶液，然后加入纳米二氧化硅气凝胶对结晶活性剂进行饱和吸附，接着过滤干燥制得二氧化硅气凝胶负载活性剂，再与硅酸盐水泥、硅灰、石英砂、减水剂、保水剂、可再分散乳胶粉研磨混合均匀而制得。本发明提供的防水涂料，利用二氧化硅气凝胶负载活性剂对结晶活性剂起到了缓释作用，防止结晶活性剂的过早结晶，使得结晶活化剂缓慢释放出来，渗透混凝土毛细孔中，生成不溶性结晶体，阻塞了毛细孔使得混凝土更加致密，从而使得混凝土具有更好的防水性能。
