Xonotlite fiber intercalation expanded vermiculite composite thermal insulation material as well as preparation and application thereof
The invention provides a xonotlite fiber intercalation expanded vermiculite composite thermal insulation material, which is prepared from the following raw materials in parts by mass: 10 to 20 parts of expanded vermiculite, 10 to 45 parts of quick lime and 10 to 45 parts of quartz sand. The expanded vermiculite is activated expanded vermiculite obtained by heating vermiculite raw ore at 300-1000 DEG C for 1-10 minutes; the quick lime is quick lime powder obtained by taking heavy calcium carbonate as a raw material, heating the heavy calcium carbonate to 700-1200 DEG C at a heating rate of 3 DEG C/min, preserving heat for 3-6 hours, cooling, crushing and sieving with a 300-400-mesh sieve; and the quartz sand is quartz sand powder which is ground to pass through a 300-400-mesh sieve. The composite thermal insulation material disclosed by the invention has excellent high-temperature thermal insulation performance and thermal stability. The invention also provides a method for preparing the composite thermal insulation material, which has the characteristics of wide raw material source, simple process, low production cost and the like.
本发明提供一种硬硅钙石纤维插层膨胀蛭石复合隔热材料，以膨胀蛭石、生石灰和石英砂作为原材料制备得到，各原料的质量份数如下：膨胀蛭石10‑20份，生石灰10‑45份，石英砂10‑45份；膨胀蛭石是由蛭石原矿在300‑1000℃加热1‑10min得到的经活化的膨胀蛭石；生石灰是由重质碳酸钙作为原料以3℃/min的升温速率将其加热至700‑1200℃并保温3‑6h，冷却后再破碎至过300‑400目筛得到的生石灰粉末；石英砂是经研磨至过300‑400目筛的石英砂粉末。本发明的复合隔热材料具有优良的高温隔热性能和热稳定性能。本发明还提供制备复合隔热材料的方法，具有原料来源广、工艺简单、生产成本低等特点。
