Fireproof door core board and manufacturing method thereof
The invention relates to the technical field of fireproof door core preparation, and discloses a fireproof door core board which is prepared from magnesium oxide, magnesium sulfate, a plant fiber powder mixture, a modifier, a foaming agent, a release agent, silica gel, tourmaline and diatom ooze. Wherein the magnesium oxide accounts for 20-25% by weight, the magnesium sulfate accounts for 20-25% by weight, the plant fiber powder mixture accounts for 20-30% by weight, the modifier, the foaming agent, the release agent and the silica gel account for 5-15% by weight, the tourmaline accounts for 10-35% by weight, and the diatom ooze accounts for 10-30% by weight. According to the fireproof door core board, the content of Mg (OH) 2 phase in a magnesium sulfate solution can be effectively inhibited by adding the modifier in the ingredients, so that the content of high-strength 5Mg (OH) 2. MgSO4.H2O phase in the solution is increased, and the breaking strength of the modified fireproof door core board is remarkably improved.
本发明涉及防火门芯制备技术领域,公开了一种防火门芯板,防火门芯板的配方如下:包括氧化镁、硫酸镁、植物纤维粉末混合体、改性剂、发泡剂、脱模剂、硅凝胶、电气石和硅藻泥,其中按重量配制比例:氧化镁占比设为20~25%、硫酸镁占比设为20~25%、植物纤维粉末混合体占比设为20~30%、改性剂、发泡剂、脱模剂、硅凝胶占比设为5~15%、电气石占比设为10~35%和硅藻泥占比设为10~30%。该防火门芯板,通过在配料中加入改性剂能有效抑制硫酸镁溶液中Mg(OH)2相的含量,以提高溶液中高强度的5Mg(OH)2·MgSO4·H2O相的含量,从而使改性防火门芯板的抗折强度显著提高。
