Insulation board and preparation method thereof
The invention discloses an insulation board and a preparation method thereof. Relates to an insulation board with expanded perlite as a main material and a preparation method thereof. The defects that in the prior art, the cement mixing amount is high, the compression ratio is large, the material production cost is high, the water glass reaction degree is low, and the humidity and heat resistance of materials is poor are overcome. The invention discloses an alkali-activated thermal insulation material which comprises the following components in percentage by mass: 65-75% of expanded perlite, 10% of fibers, 15-25% of a cementing material and 0.1% of a water repellent, and the cementing material is an alkali-activated cementing material which takes water glass as an exciting agent and takes slag-fly ash-steel slag composite micro powder as a raw material. According to the invention, the characteristics of fast setting and hardening, high early-age strength and the like of the alkali-activated cementing material are combined, the alkali-activated cementing material is used as a cementing raw material to prepare the expanded perlite insulation board, and the expanded perlite is subjected to proper'pre-saturated water 'treatment, so that the water content in the material at the initial stage of'drying' is increased, and the'curing 'stage and the'drying' stage in the traditional process are combined into one.
一种保温板及其制备方法。涉及以膨胀珍珠岩为主料的保温板及其制备方法的改进。解决现有技术水泥掺量偏高、压缩比较大、材料生产成本较高，以及水玻璃反应程度较低、材料耐湿热性能较差等不足。按质量份计包括：65%～75%的膨胀珍珠岩、10%的纤维、15%～25%的胶凝材料和0.1%的憎水剂，胶凝材料为：以水玻璃为激发剂，以矿渣‑粉煤灰‑钢渣复合微粉为原料的碱激发胶凝材料。本发明结合碱激发胶凝材料凝结硬化快、早龄期强度高等特点，以碱激发胶凝材料为胶结原料制备膨胀珍珠岩保温板，并通过膨胀珍珠岩适当“预饱水”处理，增加“烘干”初始阶段材料内部水分含量，使传统工艺中的“养护”、“烘干”阶段合二为一。
