Saltpetering-free low-alkalinity high-fire-resistance interior and exterior wall facing mortar and preparation method thereof
The invention relates to saltpetering-free low-alkalinity high-fire-resistance interior and exterior wall facing mortar and a preparation method thereof. The building material is mainly prepared from the following components in parts by weight: 100-300 parts of phosphoaluminate cement, 5-50 parts of gypsum, 500-800 parts of aggregate, 10-100 parts of mineral filler, 0.5-2 parts of thickening agent, 1-5 parts of wood fiber, 0.2-4 parts of retarder, 1-6 parts of water repellent, 0.2-0.5 part of air entraining agent, 0.2-1 part of water reducing agent and 5-50 parts of redispersible latex powder. The mortar overcomes the defects of easy efflorescence, high alkalinity and no fire resistance of the existing facing mortar due to the adoption of Portland cement (including white Portland cement) or a ternary system (Portland cement high-alumina cement-gypsum) as a main cementing material, and due to the adoption of aluminophosphate cement as the main cementing material and gypsum as an auxiliary cementing material, aggregate and mineral filler are matched, so that the material has the advantages of no efflorescence, low alkalinity, high fire resistance and the like.
本发明涉及一种无泛碱低碱度高耐火内外墙饰面砂浆及其制备方法，主要由以下的组分按照以下的重量份数比制备而成：磷铝酸盐水泥100‑300份石膏5‑50份骨料500‑800份矿物填料10‑100份增稠剂0.5‑2份木质纤维1‑5份缓凝剂0.2‑4份憎水剂1‑6份引气剂0.2‑0.5份减水剂0.2‑1份可再分散乳胶粉5‑50份。该发明克服了现有饰面砂浆由于采用硅酸盐水泥(包括白色硅酸盐水泥)或三元体系(硅酸盐水泥‑高铝水泥‑石膏)为主要胶凝材料，存在易泛碱、含碱度高、不耐火的缺点，通过采用磷铝酸盐水泥作为主要胶凝材料，石膏作为辅助胶凝材料，配合骨料和矿物填料，具有无泛碱、低碱度、高耐火等优点。
