Lightweight high-strength mixed-phase phosphogypsum-based fireproof door core plate and preparation method thereof
The invention belongs to the field of fireproof door core boards, and discloses a lightweight high-strength mixed-phase phosphogypsum-based fireproof door core board and a preparation method thereof. The raw materials comprise semi-hydrated-anhydrous mixed phase ardealite polypropylene short fibers, wood flour, an animal foaming agent, a superplasticizer, a composite foam stabilizer, a fiber modifier, a retarder, a fluidity improver, a moisture-proof agent, a consolidation agent and water according to the solid concentration. The dry density of the fireproof door core board prepared by the invention is 350-395 kg/m < 3 >, the absolute dry compressive strength can reach 0.8-1.35 MPa, the absolute dry breaking strength can reach 0.5-0.8 MPa, and the combustion performance can meet the A1 fireproof grade of GB8624-2006 Classification of Combustion Performance of Building Materials and Products. The mixed-phase ardealite-based fireproof door core board is light in weight, high in strength, excellent in fire resistance, low in manufacturing comprehensive cost, simple in production process, green and environment-friendly, and can effectively solve the problems that aluminum silicate wool, rock wool and mineral wool door core boards are complex in manufacturing process, foamed polystyrene and extruded foamed polystyrene door core boards are high in combustion smoke toxicity and low in fire resistance. And the magnesium chloride door core board is an excellent energy-saving fireproof door core board.
本发明属于防火门芯板领域，公开了一种轻质高强混合相磷石膏基防火门芯板及其制备方法。原料组成包括半水—无水混合相磷石膏聚丙烯短纤维、木粉、动物发泡剂、高效减水剂、复合稳泡剂、纤维改性剂、缓凝剂、流动度改善剂、防潮剂、固结剂、水按照固体浓度计。本发明制备的防火门芯板干密度350~395kg/m3，绝干抗压强度可达0.8~1.35MPa，绝干抗折强度可达0.5~0.8MPa，燃烧性能满足GB8624‑2006《建筑材料及制品燃烧性能分级》的A1级防火等级。混合相磷石膏基防火门芯板轻质、强度高、耐火性能优良，制作综合成本低，生产工艺简单，绿色环保，可以有效解决了硅酸铝棉、岩棉、矿物棉门芯板制作工艺复杂，发泡聚苯乙烯、挤压发泡聚苯乙烯门芯板燃烧烟毒性高，氯镁门芯板容易吸潮返卤泛霜问题，是一种优良节能型防火门芯板。
