Nanometer environment-friendly anti-freezing and waterproof gypsum block
The invention relates to the technical field of building material product gypsum blocks. The problems that a waterproof gypsum block is poor in anti-freezing capacity and high in cost, and raw materials are polluted are solved. The key points of the scheme are as follows: a proper amount of ethylene glycol, nano silica sol (or silica gel), viscose powder or common glue, styrene-acrylic emulsion (or acrylic emulsion), an emulsifier, sodium carboxymethyl cellulose and the like are respectively poured into a water tank to prepare a waterproof liquid, so as to produce the nano environment-friendlyanti-freezing and waterproof gypsum brick-2. The invention relates to a formula process. Silica sol styrene-acrylic emulsion (or acrylate emulsion), an emulsifier, sodium carboxymethyl cellulose andthe like are polymerized into a waterproof film, the used waterproof material and adhesion promoter are pollution-free and are directly added into water, the formation of the waterproof film is prevented from being influenced by ethylene glycol, the formula process is simple, and a large number of anti-freezing and waterproof gypsum blocks required by outer walls and toilets can be produced.
技术领域：建材产品石膏砌块。解决问题：解决防水石膏砌块防冻能力不强，成本高，原料有污染的问题。方案要点：用适量乙二醇、纳米硅溶胶(或者硅胶)、粘胶粉或者普通胶水、苯丙乳液(或者丙烯酸乳液)、乳化剂、羧甲基纤维素钠等分别倒入水箱中制作防水液生产纳米环保防冻防水石膏砌块‑2。该发明为配方工艺发明，靠硅溶胶苯丙乳液(或者丙烯酸脂乳液)、乳化剂、羧甲基纤维素钠等聚合成防水膜，所用防水材料及助粘剂无污染，都直接加入水中，避免乙二醇影响防水膜的形成，配方工艺简单，可以大量生产出外墙和卫生间需要的防冻防水石膏砌块。
