Inorganic-organic lightweight aggregate aerogel composite thermal insulation material
The invention discloses an inorganic-organic lightweight aggregate aerogel composite thermal insulation material which comprises the following components in parts by weight: lightweight aggregate: 10-50 parts of polyphenyl granules, 10-50 parts of expanded and vitrified microbeads, 20-40 parts of expanded perlite, 20-40 parts of fly ash hollow microbeads and 15-25 parts of aerogel; a cementing material: 15-40 parts of a cement-based inorganic material; additives: 1.5 to 4 parts of high-viscosity cellulose ether, 1.5 to 4 parts of ash calcium powder and 1.5 to 4 parts of lignocellulose; the preparation method comprises the following steps: S1, mixing and preparing the lightweight aggregate, namely mixing and stirring the polyphenyl granules, the expanded and vitrified micro-beads, the expanded perlite, the fly ash hollow micro-beads and the aerogel to prepare the lightweight aggregate. Good durability, crack resistance and compressive strength are guaranteed through the cement-based inorganic material, the bonding strength and durability of the thermal insulation material can be improved through the high-viscosity cellulose ether, the crack resistance and durability of the thermal insulation material can be improved through the ash calcium powder, and the tensile strength and durability of the thermal insulation material can be improved through the lignocellulose.
本发明公开了一种无机‑有机轻集料气凝胶复合保温材料，包括以下重量份：轻集料：聚苯颗粒10‑50份、膨胀玻化微珠10‑50份、膨胀珍珠岩20‑40份、粉煤灰空心微珠20‑40份、气凝胶15‑25份；胶结料：水泥基无机材料15‑40份；添加剂：高粘度纤维素醚1.5‑4份、灰钙粉1.5‑4份、木质纤维素1.5‑4份；其制备方法如下：S1、轻集料混合制备，将聚苯颗粒、膨胀玻化微珠、膨胀珍珠岩、粉煤灰空心微珠以及气凝胶进行混合搅拌，制备得到轻集料。本发明通过水泥基无机材料保证良好的耐久性、抗裂性和抗压强度，高粘度纤维素醚可以增加保温材料的粘结强度和耐久性，灰钙粉可以增加保温料的抗裂性和耐久性，木质纤维素可以增加保温材料的抗拉强度和耐久性。
