High-adhesion waterproof gypsum tile adhesive and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to a high-adhesion waterproof gypsum tile adhesive. The high-adhesion water-resistant gypsum tile adhesive is prepared from the following raw materials in parts by weight: 50 to 60 parts of II type anhydrous gypsum, 30 to 45 parts of quartz sand, 3 to 5 parts of cement, 2 to 5 parts of mineral powder, 0.6 to 1.8 parts of latex powder, 0.05 to 0.12 part of a water reducing agent, 0.1 to 0.25 part of a water-retaining agent and 0.10 to 0.15 part of a retarder. The selected II-type anhydrous gypsum powder is mainly anhydrous gypsum prepared by adopting a medium-high temperature calcination (600-850 DEG C) technology, harmless transition of harmful impurities is realized through medium-temperature calcination, the negative influence of the harmful impurities on the performance of the phosphogypsum is eliminated, the performance and quality stability of downstream products are ensured, and the production cost is reduced. The active activated cementing material has the characteristics of fast setting and hardening, micro-expansion in volume, high bonding strength and the like, and highly accords with the indoor tile adhesive technology and wall bonding material index requirements, and the main hydration product calcium sulfate dihydrate of the cementing material has good compatibility with a gypsum base material; and a complete industrial chain can be formed with a phosphogypsum product system mainly pushed in the market.
本申请属于建筑材料领域，尤其涉及一种高粘结度耐水石膏瓷砖胶。本申请的高粘结度耐水石膏瓷砖胶有以下重量份的原料制成：Ⅱ型无水石膏50‑60份、石英砂30‑45份、水泥3‑5份、矿粉2‑5份、乳胶粉0.6‑1.8份、减水剂0.05‑0.12份、保水剂0.1‑0.25份、缓凝剂0.10‑0.15份。所选用的Ⅱ型无水石膏粉主要是采用中高温煅烧(600℃～850℃)技术制备的无水石膏，通过中温煅烧实现有害杂质的无害化变迁，消除了有害杂质对磷石膏性能的负面影响，保证下游产品性能与质量稳定性，经活性激发后的胶凝材料具有凝结硬化快、体积微膨胀、粘结强度高等特点，高度契合室内瓷砖胶技术和墙体粘结材料指标要求，且该胶凝材料主要水化产物二水硫酸钙与石膏基材具有良好兼容性，能够与市场上主推的磷石膏产品体系形成完整产业链。
