Modified A-grade fireproof thermal insulation material and preparation method thereof
The invention provides a modified A-grade fireproof thermal insulation material. The modified A-grade fireproof thermal insulation material is prepared from the following raw materials in parts by weight: 20-70 parts of inorganic microbeads, 15-40 parts of a cementing material, 30-50 parts of water, 1-8 parts of inorganic whiskers, 8-25 parts of aluminum dihydrogen phosphate, 20-35 parts of inorganic nanoparticles, 2-12 parts of inorganic fibers and 20-50 parts of inorganic aerogel powder. The preparation method of the modified A-grade fireproof thermal insulation material comprises the following steps: 1.1) uniformly stirring and mixing; and 1.2) carrying out mold box compression molding or rolling molding on the mixed slurry, then curing, and then maintaining. Due to the addition of modified materials such as the inorganic nano particles and the inorganic aerogel powder, the combustion performance reaches grade-A fireproof performance, the thermal insulation performance is not obviously reduced, the standard requirement is met, and the heat conductivity coefficient is 0.023-0.050 W/(m.K); the inorganic whisker and the inorganic fiber are both reinforcing materials, so that the strength, the hardness, the tensile strength, the compression resistance, the bending resistance, the durability and the like are obviously improved.
本申请提供了一种改性A级防火的保温材料，原料包括：20～70份的无机微珠、15～40份的胶凝材料、30～50份的份的水、1～8份的无机晶须、8～25份的磷酸二氢铝、20～35份的无机纳米颗粒、2～12份的无机纤维、20～50份的无机气凝胶粉末。一种改性A级防火的保温材料的制备方法，1.1)搅拌混合均匀；1.2)将混合浆料进行模箱压制成型或辊压成型，然后固化，然后养护。由于添加了无机纳米颗粒与无机气凝胶粉末这些改性材料，使得燃烧性能达到了A级防火，且保温性能未明显降低、达到标准要求，导热系数为0.023～0.050W/(m·K)；无机晶须以及无机纤维均为增强材料，显然地提高了强度、硬度、抗拉、抗压、抗弯曲、耐久性等性能。
