Technical field: gypsum blocks for building materials, the invention solves the problem of acid and alkali resistance and high and low temperature of gypsum blocks; the main points of the program are: nano silica sol (or silica sol), styrene acrylic emulsion, polyvinyl alcohol acetaldehyde two aldehyde, modified sodium silicate, polyacrylic emulsion, various auxiliaries, ordinary glue or adhesive powder, glycol (the proportion of each material is determined by their respective concentration), respectively, respectively. In water solution, water-proof solution is formed to produce acid-alkali-resistant, high and low temperature water-proof gypsum block. The invention relies on nano silica sol (or silica sol), styrene acrylic emulsion, polyvinyl alcohol acetaldehyde two aldehyde, modified sodium silicate, polyacrylic acid emulsion, various auxiliaries are polymerized into waterproof membrane, and waterproof materials and auxiliary adhesives are basically pollution-free, respectively, adding water to form water proofing liquid, and avoiding affecting the formation of waterproof membrane and simple production process. Disinfection capacity, the use of polyvinyl glycol acetal to enhance the product's acid and alkali resistance and high temperature resistance, the production of chemical industry plant-building products.
【技术实现步骤摘要】
耐酸碱耐高低温防水环保石膏砌块
：建材产品石膏砌块
技术介绍
：市场上缺乏耐酸碱耐高低温专用的防水石膏砌块。
技术实现思路
：就是用纳米硅溶胶(或者硅溶胶)、苯丙乳液、聚乙烯醇缩乙二醛，改性硅酸甲钠，聚丙烯酸脂乳液，各类助剂，普通胶水或者粘胶粉、乙二醇(各材料比例由各自浓度而定)分别加入水溶液中，形成防水溶液生产石膏砌块。该专利技术为配方与工艺专利技术，纳米硅溶胶(或者硅溶胶)、苯丙乳液、聚乙烯醇缩乙二醛，改性硅酸甲钠，聚丙烯酸脂乳液，各类助剂助粘剂形成防水膜；所用防水材料和助粘剂基本无污染，分别加入水中形成防水液，也避免影响防水膜的形成，生产工艺简单；聚乙烯醇缩乙二醛的加入增强产品耐酸碱能力和抗高温能力，乙二醇加入增强产品防冻及消毒能力，可生产出化工行业建厂专用产品。实施方式：将以上防水溶液加入石膏粉中搅拌成石膏浆再倒入设备模具中冷却干燥，自然成型。
