Calcium magnesium silicate thermal insulation material and preparation method and application thereof
The invention discloses a preparation method of a calcium magnesium silicate thermal insulation material. The preparation method comprises the following steps: S1, preparing silica sol, S2, preparingcalcium oxide powder and active magnesium oxide powder, S3, preparing raw slurry, S4, preparing a magnesium-xonotlite active slurry, and S5, standing, precipitating the magnesium-xonotlite active slurry, removing the supernatant, injecting the lower active slurry into a forming mold, filtering out water in the slurry at a pressurization rate of 5-10N/s, maintaining the pressure for 60s at 2-4KN, demolding, and drying to obtain the finished product. By adopting the preparation method of the calcium magnesium silicate thermal insulation material, the prepared plate has the characteristics of light weight, incombustibility, environmental protection (no formaldehyde or benzene), sound attenuation, heat transfer, fire prevention, moisture prevention, stress resistance, excellent thermal insulation performance, excellent durability and the like, and meets the requirements of the current national and provincial building energy-saving design standard and fire prevention specification.
本发明公开了一种硅酸钙镁保温材料的制备方法，包括以下步骤：S1、制备硅溶胶；S2、制备氧化钙粉和活性氧化镁粉；S3、制备生料浆；S4、制备镁‑硬硅钙石活性料浆；S5、静置、沉淀镁‑硬硅钙石活性料浆，除去上层清液，将下层活性料浆注入成型模具中，以5～10N/s加压速率滤去料浆中的水，2～4KN保压60s，脱模烘干，制得成品。本发明采用上述硅酸钙镁保温材料的制备方法，制成的板材具有轻质、不燃、环保(无醛无苯)、消音、输热防火、防潮、抗应力、保温隔热性能优良、耐久性优良等特点，满足了现行国家及我省建筑节能设计标准要求和防火规范要求。
