Roof light heat insulation material
Portland cement is used as a basic material of the lightweight thermal insulation material, hydrogen peroxide is used as a foaming agent, sodium dodecyl benzene sulfonate is used as a surfactant to reduce the surface tension of bubbles, calcium stearate is used as a foam stabilizer, and PP fibers are used to improve the flexibility of the material. And the light heat insulation material with porosity, heat conductivity coefficient and compressive strength meeting use requirements is obtained by adjusting the addition amount of the metakaolin. Compared with similar materials in the prior art, the raw material composition is simple, the preparation process is convenient, and production is efficient. In addition, too low addition amount of the metakaolin can cause insufficient compressive strength of the light heat insulation material, and too high addition amount of the metakaolin can cause too low porosity and too high heat conductivity coefficient of the light heat insulation material. Therefore, relative to 100 parts by weight of the Portland cement, the use amount of the metakaolin needs to be controlled to be 36-73 parts by weight.
本发明公开了一种轻质隔热保温材料，以硅酸盐水泥作为轻质隔热保温材料的基本物料，以双氧水作为发泡剂，以十二烷基苯磺酸钠作为表面活性剂，减小气泡的表面张力，以硬质酸钙作为稳泡剂，以PP纤维提高材料的柔韧性，并通过调整偏高岭土的添加量得到了孔隙率、导热系数和抗压强度满足使用需求的轻质隔热保温材料。相对于现有技术的同类材料，原料组成简单，制备工艺方便，生产高效。另外，偏高岭土的添加量过低会导致轻质隔热保温材料的抗压强度不足，偏高岭土的添加量过高会导致轻质隔热保温材料的孔隙率过低以及导热系数过高。所以，相对于100重量份硅酸盐水泥，需将偏高岭土的用量控制在36重量份‑73重量份。
