The invention relates to the technical field of building materials, and discloses a building waterproof thermal insulation material. The building waterproof thermal insulation material is characterized by comprising the following raw materials in parts by weight: 15 to 20 parts of fly ash, 5 to 10 parts of calcium stearate, 50 to 80 parts of Portland cement, 0.3 to 0.5 part of sodium phosphate, 1to 2 parts of ferric chloride, 5 to 6 parts of bentonite, 6 to 8 parts of talcum powder, 8 to 10 parts of polyphenyl granules, 3 to 5 parts of polyvinyl alcohol, 1 to 3 parts of glutinous rice glue and 6 to 8 parts of a polyacrylic emulsion. According to the building waterproof thermal insulation material and the preparation method thereof, a plurality of hydroxyl groups in phosphate molecules canform hydrogen bonds with hydroxyl groups of the Portland cement, so the cementing property of the cement and the mechanical strength of a thermal insulation layer are enhanced; a melamine cross-linking agent is added for a cross-linking reaction with polyvinyl alcohol, and a reaction product forms a water-insoluble interpenetrating three-dimensional network structure with polypropylene cellulose,a silicon dioxide aerogel and the glutinous rice glue, so the strength of modified polyvinyl alcohol glue after curing is improved; meanwhile, the modified polyvinyl alcohol glue is not dissolved inwater any more, so the waterproof and heat-insulating properties are effectively enhanced.
本发明涉及建筑材料技术领域，且公开了一种建筑防水保温材料，其特征在于，包括以下重量份数配比的原料：粉煤灰15‑20份、硬脂酸钙5‑10份、硅酸盐水泥50‑80份、磷酸钠0.3‑0.5份、氯化铁1‑2份、膨润土5‑6份、滑石粉6‑8份、聚苯颗粒8‑10份、聚乙烯醇3‑5份、糯米胶1‑3份、聚丙烯酸乳液6‑8份。该建筑防水保温材料及其制备方法，而且磷酸盐分子中的多个羟基也可以和硅酸盐水泥的经羟基成氢键，从而增强了水泥的胶结性能和保温层的力学强度；加入三聚氰胺交联刘使之与聚乙烯醇发生交联反应，与聚丙烯纤维素、二氧化硅气凝胶、糯米胶形成不溶于水的互穿立体网络结构，使改性后聚乙烯醇胶水固化后的强度增加，且不再溶于水，有效的增强了防水保温性能。
