Composite cement foaming fireproof door core plate
The invention discloses a composite cement foaming fireproof door core plate, and belongs to the technical field of fireproof doors. The preparation method comprises the following step: preparing thefollowing raw materials in parts by weight: 10-20 parts of magnesium chloride, 10-15 parts of sodium polyacrylate, 4-6 parts of a foaming agent, 5-9 parts of sodium pyrophosphate, 15-20 parts of lime,15-18 parts of cement, 30-34 parts of mica powder, 30-42 parts of furnace slag and 16-18 parts of lime powder. The mica powder is added, so that the fireproof performance of the door core plate can be enhanced; meanwhile, nitrogen is added into the heated raw materials during pouring forming, the foaming effect of the fireproof door core plate can be effectively improved, and the self weight of adoor in the later period is reduced; and sodium polyacrylate is added as a corrosion and scale inhibitor and a water quality stabilizer, so that the direct fusion degree and temperature of the raw materials and water can be effectively enhanced, and corrosion is reduced in the later use process.
本发明公开了一种复合水泥发泡防火门芯板，属于防火门技术领域，包括如下制备步骤：原料准备，按重量份数计，包括氯化镁10～20份、聚丙烯酸钠10～15份、发泡剂4～6份、焦磷酸钠5～9份、石灰15～20份、水泥15～18份、云母粉30～34份、炉渣30～42份和粉白灰16～18份。本发明添加云母粉能够增强门芯板的防火性能，同时在浇筑成型时对加热后的原料中加入氮气，能够有效增加防火门芯板的发泡效果，减少后期门的自重；添加聚丙烯酸钠用作缓蚀防垢剂和水质稳定剂，能够有效增强原料与水直接的融合度和温度度，在后期使用过程中减少腐蚀。
