Waste stone powder light microcrystal foaming thermal insulation material and manufacturing method thereof
The invention discloses a waste stone powder light microcrystal foaming thermal insulation material and a preparation method thereof, and belongs to the technical field of building thermal insulationmaterials. In the implementation process, waste stone powder is used as a main raw material and mixed with a foaming agent and auxiliary materials to prepare the light microcrystal foaming thermal insulation material, stone powder resources can be fully utilized, and the production cost is reduced. By controlling the type and the mass ratio of the foaming agent, the pore uniformity of the light microcrystal foaming thermal insulation material is obviously improved, and the thermal insulation effect and the strength are obviously improved. By controlling the mass ratio of the waste stone to theauxiliary materials to be (150-300): 1, the stability of the product is obviously improved, and the product has an ultralow heat conductivity coefficient and a good thermal insulation effect. In addition, the technologies of dry ball milling, dry granulation and double-layer roller kiln are adopted in the preparation process, the firing temperature is low, the preparation period is short, the energy consumption is low, the yield is high, and kiln blockage accidents are not likely to happen.
本发明公开了一种废石粉轻质微晶发泡保温材料及其制备方法，属于建筑保温材料技术领域。在实施过程中采用废石粉作为主要原料混合发泡剂和辅料用于制备轻质微晶发泡保温材料，可以充分利用石粉资源，降低了生产成本，通过控制发泡剂的种类以及质量比，明显提高了轻质微晶发泡保温材料孔隙均匀度、使保温效果和强度明显提高，通过控制废石料与辅料的质量比为150‑300：1，明显提高了产品的稳定性，使产品具有超低的导热系数，保温效果好；另外在制备过程中采用干法球磨、干法造粒、双层辊道窑的技术，烧制温度低，制备周期短，能耗低、产量大，不容易发生堵窑事故。
