Building energy-saving thermal insulation material and preparation method thereof
The invention belongs to the technical field of thermal insulation materials, and particularly relates to a building energy-saving thermal insulation material and a preparation method thereof. The method comprises the following steps: taking fly ash and coal gangue as raw materials, and taking magnesium carbonate, strontium carbonate, chopped glass fibers, nano silicon oxide whiskers and nano silicon carbide whiskers as additives; mixing raw materials and additives to form a mixed material, adding glucose, P123 and a polyvinyl alcohol aqueous solution, carrying out wet milling by using a ball mill, and uniformly mixing to prepare slurry; drying, crushing and sieving the obtained slurry, filling the sieved powder into a mold, then putting the mold into a heating furnace, and carrying out roasting, foaming and pore-forming; after roasting foaming pore-forming is completed, performing furnace cooling to the normal temperature, and obtaining the building energy-saving thermal insulation material, wherein the compressive strength of the prepared thermal insulation material ranges from 35.8 MPa to 39.6 MPa, the heat conductivity coefficient ranges from 0.041 W/(m.K) to 0.078 W/(m.K), the performance is excellent, and high-value recycling of waste can be achieved.
本发明属于保温材料技术领域，具体涉及一种建筑节能保温材料及其制备方法。本发明是通过以粉煤灰和煤矸石为原料，碳酸镁、碳酸锶、短切玻璃纤维、纳米氧化硅晶须和纳米碳化硅晶须作为添加剂；将原料和添加剂混合形成混合物料，添加葡萄糖、P123和聚乙烯醇水溶液然后用球磨机进行湿磨，混合均匀并制成料浆；将得到的料浆进行干燥，粉碎过筛，将过筛后的粉料填充到模具内，然后置于加热炉中，进行焙烧发泡造孔；焙烧发泡造孔完成后，随炉冷却至常温，获得建筑节能保温材料，所制备的保温材料的抗压强度为35.8～39.6MPa，导热系数为0.041～0.078W/(m·K)，性能优异，能够实现废物高价值再利用。
