Magnesium oxide for damp-proof fireproof cable and preparation method thereof
The invention provides magnesium oxide for a damp-proof fireproof cable and a preparation method of the magnesium oxide. The preparation method of the magnesium oxide for the damp-proof fireproof cable comprises the following steps: mixing magnesium oxide, kaolin talc, aluminum hydroxide and zirconium silicate; preparing a solution from high-hydrogen-content organic silicon resin, high-hydrogen-content organic silicon oil, an aluminate coupling agent and solvent oil; and mixing the material and the solution, and baking the mixture in a low-temperature rotary furnace to obtain the magnesium oxide for the moisture-proof fireproof cable. The invention also discloses the magnesium oxide for the moisture-proof fireproof cable prepared by the method. The preparation method of the magnesium oxidefor the moistureproof fireproof cable is simple and easy to implement, the prepared magnesium oxide for the moistureproof fireproof cable has excellent moistureproof and insulating properties, and the insulation is still greater than or equal to 1000 Momega under the condition that the humidity is 80% RH for 5 hours.
本发明提供一种防潮型防火电缆用氧化镁及其制备方法。防潮型防火电缆用氧化镁的制备方法包括以下步骤：将氧化镁、高岭土滑石，氢氧化铝和硅酸锆混合；将高含氢有机硅树脂、高含氢有机硅油、铝酸酯偶联剂、溶剂油配置成溶液；将物料和溶液混合后在低温回转炉内烘制得到防潮型防火电缆用氧化镁。本发明还公开了采用上述方法制备而成的防潮型防火电缆用氧化镁。本发明防潮型防火电缆用氧化镁制备方法简单、易行，制备得到的防潮型防火电缆用氧化镁具有优异的防潮绝缘性能，在湿度80％RH，5小时的情况下，绝缘仍≥1000MΩ。
