Inorganic intumescent cured foam material and preparation method thereof
The invention discloses an inorganic intumescent cured foam material and a preparation method thereof. The inorganic intumescent cured foam material is prepared by mixing, expanding and foaming 20%-30% of a material A, 45%-55% of a material B and 20%-30% of water, wherein the material A is prepared from the following raw materials in percentage by weight: 10%-30% of fly ash, 10%-30% of bentonite, 5%-20% of calcium carbonate and 40%-60% of phosphate cement; and the material B is prepared from the following raw materials in percentage by weight: 15%-25% of 1-hydroxyethylidene-1, 1-diphosphonic acid, 1%-10% of ammonium chloride, 1%-5% of sodium phosphate, 0.1%-0.8% of cocamidopropyl betaine and 50%-80% of water. The inorganic intumescent cured foam material has the characteristics of non-combustibility, almost no heat release, strong bonding and reinforcing capability, high compressive strength, controllable foaming times and the like, has a very obvious effect of preventing and controlling spontaneous combustion of coal, and is simple and safe in operation process and low in cost.
本发明公开了一种无机膨胀型固化泡沫材料及其制备方法。该无机膨胀型固化泡沫材料由20％～30％A料、45％～55％B料和20％～30％水混合膨胀发泡而成，其中A料由以下重量百分比的原料制得：粉煤灰10％～30％、膨润土10％～30％、碳酸钙5％～20％、磷酸盐水泥40％～60％；B料由以下重量百分比的原料制得：羟基乙叉二膦酸15％～25％、氯化铵1％～10％、磷酸钠1％～5％、椰油酰胺丙基甜菜碱0.1％～0.8％和水50％～80％。本发明的无机膨胀型固化泡沫材料具有不燃、几乎不放热、粘结加固能力强、抗压强度大、发泡倍数可控等特点，防治煤自燃效果十分显著，操作工艺简单、安全、成本低廉。
