Wooden fireproof door core plate and preparation method thereof
The invention discloses a wooden fireproof door core plate and a preparation method thereof, and the wooden fireproof door core plate is prepared from the following raw materials: perlite as aggregate, magnesium oxide, magnesium chloride, water and an auxiliary agent. The preparation method comprises the following steps: adding magnesium chloride, an auxiliary agent and water in proportion, uniformly stirring, standing for half an hour or more to prepare brine with the glass magnesium degree of 23-27, adding perlite and magnesium oxide into stirring equipment in proportion, uniformly sprayingand adding brine while stirring, stirring for 1-5 minutes until all the materials are uniformly distributed, transferring the mixed materials to a hopper, discharging to a mold frame, compressing to arequired height, and finally, curing in an environment of 30+/-5 DEG C until the moisture content is less than or equal to 12% to obtain a finished product. According to the wooden fireproof door core plate prepared by the invention, pollutants are reduced, the maintenance period of the core plate can be shortened, the turnover of sites and equipment is improved, and the production cost is reduced.
本发明公开了一种木质防火门芯板及其制备方法，由以下原料制备而成：以珍珠岩为骨料，加入氧化镁，氯化镁，水，助剂。本发明先将氯化镁、助剂与水按比例加入并搅拌均匀，静置半小时以上，制成玻镁度为23－27卤水；然后在搅拌设备中按比例加入珍珠岩、氧化镁，边搅拌边均匀喷淋加入卤水，搅拌1‑5min至所有物料均匀分布，再将混合好的物料转移至料斗，放料至模框，压缩至要求高度；最后在30±5℃环境中养护至含水率≤12％，制得成品。本发明制备的一种木质防火门芯板，在减少污染物产生的同时，还能缩短芯板的养护周期，提高场地和设备方面的周转，降低生产成本。
