Lightweight foamed ceramic insulation board prepared by regenerating waste glass and preparation method of lightweight foamed ceramic insulation board
The invention discloses a lightweight foamed ceramic insulation board prepared by regenerating waste glass and a preparation method thereof, the lightweight foamed ceramic insulation board is characterized by comprising the following materials by mass: 80-95% wt of waste glass powder, 0.1-5% wt of a foaming agent, 0.1-3% wt of a foaming aid, 0.1-2% wt of a fluxing agent and 3-20% wt of clay mineral powder, and the lightweight foamed ceramic insulation board is prepared by mixing the materials, sintering, foaming and cooling. According to the method, anhydrous borax subjected to heat treatment is added into a raw material mainly comprising waste glass powder, and the granularity and proportion of the waste glass powder, the foaming agent, the foaming aid and the clay mineral powder are adjusted, so that the sintering temperature and the sintering time are greatly reduced, and the raw material does not need to be wet-ground into slurry and then subjected to high-temperature spray drying. The manufacturing process is simple, the cost is low, and the method is a low-cost method for recycling the waste glass. The thermal insulation board prepared by the method is of a hexagonal honeycomb independent pore structure, and is small in volume density, high in compressive strength, low in water absorption rate, low in thermal conductivity and high in cost performance.
本发明公开了一种由废玻璃再生制备的轻质发泡陶瓷保温板及制备方法，其特征在于：按质量百分比，包括以下材料：废玻璃粉80～95％wt，发泡剂0.1～5％wt，发泡助剂0.1～3％wt，助熔剂0.1～2％wt和粘土矿物粉3～20％wt，以上材料混合后，经烧结发泡、冷却制备而成。通过在以废玻璃粉为主的原材料里添加经过加热处理的无水硼砂，以及调整废玻璃粉、发泡剂、发泡助剂、粘土矿物粉的粒度和配比量，大幅降低烧结温度和烧结时间，并且原材料不需要湿磨成泥浆后再进行高温喷雾干燥。制造工艺简单、成本低，是一种低成本再生利用废玻璃的方法。本发明制备的保温板为六角形蜂窝状独立气孔结构，体积密度小、抗压强度高、吸水率低、热传导率低、性价比高。
