High-strength thermal insulation concrete and preparation method thereof
The invention belongs to the field of building materials, and relates to a high-strength thermal insulation concrete and a preparation method thereof. The concrete is characterized by comprising the following raw materials in percentage by weight: 30-40% of ordinary Portland cement, 20-25% of titanium waste residues, 10-15% of red gypsum, 3-8% of a polymer emulsion, 1.5-5% of a foaming agent, 1-2%of calcium stearate, 2-3% of lithium chloride, 0.6-0.8% of a polycarboxylate water reducer, 0.1-0.3% of polypropylene fibers and 10-15% of water, wherein the polymer emulsion is formed by polymerizing a methacrylic acid sulfobetaine monomer, vinyl acetate, deionized water and a cosolvent under the action of an initiator. The prepared high-strength thermal insulation concrete is low in heat conductivity coefficient, high in strength, low in water absorption rate and good in thermal insulation effect, is an ideal building material and can be further popularized in related industries of buildings.
本发明属于建筑建材领域，涉及一种高强度保温混凝土及其制备方法，其特征在于，以质量百分数计，其配方原料的组成如下：普通硅酸盐水泥30‑40％，钛废渣20‑25％，红石膏10‑15％，聚合物乳液3‑8％，发泡剂1.5‑5％，硬脂酸钙1‑2％，氯化锂2‑3％，聚羧酸减水剂0.6‑0.8％，聚丙烯纤维0.1‑0.3％，水10‑15％；所述聚合物乳液由甲基丙烯酸磺基甜菜碱单体、醋酸乙烯酯、去离子水和助溶剂在引发剂的作用下聚合而成。本发明制备得到的高强度保温混凝土导热系数低，强度大，吸水率低，保温效果好，是一种理想的建筑材料，可进一步在建筑相关行业推广。
