Ultra-light thermal insulation material based on physical-chemical synergistic foaming and preparation method of ultra-light thermal insulation material
The invention discloses an ultra-light thermal insulation material based on physical-chemical synergistic foaming and a preparation method of the ultra-light thermal insulation material, and belongs to the technical field of building thermal insulation materials. The ultra-light thermal insulation material based on physical-chemical synergistic foaming is prepared from the following components in parts by weight: 28 to 37 parts of light calcined magnesia, 18 to 26 parts of magnesium sulfate heptahydrate, 3.6 to 5.4 parts of a foaming agent, 4.1 to 5.7 parts of a thickening agent, 0.1 to 0.4 part of a modifying agent, 1.5 to 2.3 parts of hydrogen peroxide, 0.6 to 1.3 parts of potassium iodide and 45 to 58 parts of water. The volume weight of the light thermal insulation material is greatly reduced to 60-80 kg/m < 3 >, the 7d strength is larger than or equal to 100 kPa, A-level non-combustibility is achieved, the heat conductivity coefficient is smaller than or equal to 0.038 W/(m.K), the problems that an existing cement-based thermal insulation material is high in volume weight and large in heat conductivity coefficient are effectively solved, and application and popularization of the cement-based thermal insulation material are greatly improved.
本发明公开了一种基于物理‑化学协同发泡的超轻质保温材料及其制备方法，属于建筑保温材料技术领域。本发明的基于物理‑化学协同发泡的超轻质保温材料，按重量份计，包括以下组分：轻烧氧化镁：28‑37份，七水硫酸镁：18‑26份，发泡剂：3.6‑5.4份，增稠剂：4.1‑5.7份，改性剂：0.1‑0.4份，过氧化氢：1.5‑2.3份，碘化钾：0.6‑1.3份，水45‑58份。本发明的轻质保温材料容重大幅降低至60‑80kg/m3，且7d强度≥100kPa，A级不燃，导热系数≤0.038W/(m·K)，有效解决了现有水泥基保温材料容重高、导热系数大的问题，大大提高了水泥基保温材料的推广与应用。
