Composite building material and preparation method thereof
The invention discloses a composite building material and a preparation method thereof, and the composite building material comprises the following raw materials by weight: 10-20 parts of calcium silicate powder, 15-25 parts of aluminum silicate powder, 5-10 parts of magnesium oxide, 10-15 parts of low density polyethylene resin, 8-12 parts of a modified basalt-montmorillonite composite material, and 0.5-1 part of carbon black. The polyurethane is grafted on the basalt fiber, so that the pore size of the basalt fiber is effectively reduced, the heat conduction is limited, meanwhile, the polyurethane has a relatively low heat conductivity coefficient, and the polyurethane and the basalt fiber have a synergistic effect to jointly inhibit various heat transfer modes, so that the heat preservation and heat insulation performance of the composite building material is improved; besides, the basalt fiber is modified, so that the dispersing performance of the basalt fiber is improved, the structure of the composite building material is more compact, and the mechanical property of the composite building material is further improved.
本发明公开了一种复合建筑材料及其制备方法，以重量份计，包括如下组分的制备原料：硅酸钙粉10‑20份、硅酸铝粉15‑25份、氧化镁5‑10份、低密度聚乙烯树脂10‑15份、改性玄武岩‑蒙脱土复合材料8‑12份、碳黑0.5‑1份，本发明通过将聚氨酯接枝在玄武岩纤维上，有效的降低了玄武岩纤维的孔径尺寸，使热传导受到限制，同时聚氨酯本身具有较低的导热系数，两者协同作用，共同抑制各种热传递的方式，从而提高了复合建筑材料的保温隔热性能；此外，通过对玄武岩纤维进行改性，提高了玄武岩纤维的分散性能，使复合建筑材料的结构更加密实，进而提高了复合建筑材料的力学性能。
