Nano-modified cement-based thermal insulation material for high-strength thermal insulation prefabricated member and preparation method thereof
The invention discloses a nano-modified cement-based thermal insulation material for a high-strength thermal insulation prefabricated member and a preparation method thereof. The nano-modified cement-based thermal insulation material for the high-strength thermal insulation prefabricated member is prepared from 400-550 parts of cement, 5-100 parts of silane modified nano silica fume, 0.5-3 parts of a water reducing agent, 4-8 parts of a nano crystal nucleus early strength agent, 0.5-10 parts of fibers, 0.0001-0.1 part of an air entraining agent, 1-50 parts of a modifier, 1-150 parts of thermal insulation particles and 375-575 parts of sand. According to the present invention, the requirements of the A-grade fireproof material can be met, the heat conductivity coefficient can be less than or equal to 0.25 (W/m.k) when the mortar density is 1000-1500 g/L through the combination and the proportioning of the raw materials, and the strength of the final finished product at 28 d can be significantly improved, and can achieve more than 20 MPa.
本发明公开了高强隔热预制件用纳米改性水泥基隔热材料及其制备方法，其中，一种高强隔热预制件用纳米改性水泥基隔热材料，包括水泥400‑550份，硅烷改性纳米硅灰5‑100份，减水剂0.5‑3份，纳米晶核早强剂4‑8份，纤维0.5‑10份，引气剂0.0001‑0.1份，改性剂1‑50份，保温颗粒1‑150份，沙子375‑575份。本发明能够达到A级防火材料的要求，并且通过原料的组合和比配，可以在砂浆密度为1000‑1500g/L时，使导热系数≤0.25(W/m·k)，并显著提高最终成品在28d时的强度，在28d时的强度可以达到20MPa以上。
