Corrosion-resistant high-strength environment-friendly fireproof door core plate and manufacturing method
The invention discloses a corrosion-resistant high-strength environment-friendly fireproof door core plate and a manufacturing method, and relates to the field of fireproof doors. The corrosion-resistant high-strength environment-friendly fireproof door core plate comprises non-woven fabric layers and gypsum grouting layers, the non-woven fabric layers are distributed on the surfaces of the two sides of the gypsum grouting layers, and the gypsum grouting layers and the non-woven fabric layers are poured into an integral structure; the manufacturing method of the door core plate comprises the steps that alpha high-strength gypsum powder, fireproof glue, a reinforcing agent, short fibers, water and a retarder are prepared and put into stirring equipment, and raw material slurry is obtained through stirring; the slurry mixed with a foaming agent is injected into a forming mold which is made of an aluminum alloy material and is paved with non-woven fabric; and after the gypsum slurry is solidified and formed, the aluminum alloy mold is opened, the gypsum-based fireproof door core plate is taken out and conveyed to a drying room, drying, stacking and packaging are achieved. According to the corrosion-resistant high-strength environment-friendly fireproof door core plate and the manufacturing method, the gypsum-based fireproof door core plate does not contain chloride ions, the PH value is neutral, the phenomena of halogenation, alkali efflorescence, odor efflorescence and fishy smell efflorescence do not exist, the non-woven fabric is laid on the surface of the aluminum alloy mold, and the flexural and compressive strength is improved due to the fact that the slurry and the non-woven fabric are mixed together.
本发明公开了一种抗腐蚀高强环保防火门芯板及制造方法，涉及防火门领域，其包括无纺布层和石膏灌浆层，所述无纺布层分布在石膏灌浆层的两侧表面，且所述石膏灌浆层和无纺布层浇筑为整体结构，门芯板的制造步骤为：准备ɑ高强石膏粉、防火胶、增强剂、短纤维、水以及缓凝剂原料投入搅拌设备中，通过搅拌得到原料浆液；将参入发泡剂的浆液注入到已经铺垫无纺布的铝合金材质的成型模具中；等石膏浆料凝固成型后打开铝合金模具，取出石膏基防火门芯板运到烘干房，烘干后码盘打包。本发明石膏基防火门芯板不含氯离子，PH值为中性，不存在返卤、返碱、返臭、返腥现象，由于铝合金模具表面铺贴了无纺布，浆料和无纺布混合在一起提高了抗折抗压强度。
