Building energy-saving thermal insulation material and preparation method thereof
The invention discloses a building energy-saving thermal insulation material and a preparation method thereof, and relates to the technical field of building thermal insulation materials, the building energy-saving thermal insulation material comprises the following components: 40-50 parts of silicon dioxide aerogel, 10-20 parts of expanded perlite, 5-10 parts of clay, 5-10 parts of glass fiber, and an inorganic binder, the inorganic binder is liquid water glass, and the inorganic binder is water glass. The dosage is 2-5% of the total mass of the components. The silicon dioxide aerogel is ultra-light in volume weight, small in heat conductivity coefficient and excellent in heat preservation performance and has excellent heat preservation performance and mechanical performance after being compounded with the expanded perlite, the glass fibers and the clay, and after the silicon dioxide aerogel is combined with the inorganic binder, the porosity and the specific surface area of the material are increased, and the pore size and the heat conductivity are reduced; the glass fiber can enhance the strength of the thermal insulation material, solves the problems that the existing thermal insulation material is poor in thermal insulation efficiency and part of materials are inflammable, and achieves the effects of reducing pollution, improving the material strength and enhancing thermal insulation.
本发明公开了一种建筑节能保温隔热材料及其制备方法，涉及建筑隔热材料技术领域，该建筑节能保温隔热材料，包括以下成分：二氧化硅气凝胶40‑50份、膨胀珍珠岩10‑20份、粘土5‑10份、玻璃纤维5‑10份、无机粘结剂，所述无机粘结剂是液体水玻璃，用量为总成分质量的2％‑5％。本发明通过使用二氧化硅气凝胶，其容重超轻，导热系数小，保温性能优良，在与膨胀珍珠岩、玻璃纤维和粘土复合，兼具有极佳保温性能和机械性能，在与无机粘结剂结合后，材料的孔隙率和比表面积增高，孔径尺寸和热导率下降，玻璃纤维可以增强隔热材料的强度，解决现有保温隔热材料保温热效率差，部分材料易燃的问题，达到减少污染，提高材料强度和加强保温隔热的效果。
