Lightweight composite building partition board and preparation method thereof
The invention provides a lightweight composite building partition board and a preparation method thereof, and belongs to the technical field of resource utilization. The light composite building partition board comprises the following components in percentage by mass: 40-45% of plant ash, 20-25% of coal ash slag, 15-20% of cement, 8-10% of perlite, 0.5-1% of special resin rubber powder for mortar, 5-10% of styrene-acrylic emulsion and 0.5-1% of polyethylene powder. The solid content of the styrene-acrylic emulsion is 40 to 50 percent. The compressive strength of the lightweight composite building partition board is 4.2 MPa; after the board is stood for 24 hours under the load of 1000N, the board has no crack exceeding 0.5 mm, and no crack appears; after 50 times of freezing and thawing cycles, the damage phenomena such as layering and stripping are avoided; the combustion performance reaches A1 level; the bending failure load/plate self-weight multiple is larger than or equal to 1.5 times, and damage does not occur when 1.5 times of self-weight is loaded; the water absorption rate is 8%.
本发明提供了一种轻质复合建筑隔墙板及其制备方法，属于资源化利用技术领域。本发明的轻质复合建筑隔墙板，以质量分数计，包括以下组分：草木灰40～45％，煤灰渣20～25％，水泥15～20％，珍珠岩8～10％，砂浆专用树脂胶粉0.5～1％，苯丙乳液5～10％，聚乙烯粉末0.5～1％；所述苯丙乳液的固含量为40～50％。本发明轻质复合建筑隔墙板的抗压强度为4.2MPa；荷载1000N静置24h，板面无超过0.5mm的裂缝，未出现裂纹；经50次冻融循环，无起层剥落等破坏现象；燃烧性能达到A1级；抗弯破坏荷载/板自重倍数≥1.5倍，加载1.5倍自重未出现破坏；吸水率为8％。
