Magnesium oxide for damp-proof fireproof cable and application thereof
The invention provides magnesium oxide for a damp-proof fireproof cable and application thereof. The magnesium oxide for the moisture-proof fireproof cable comprises the following components in partsby weight: 95 to 99 parts of MgO; 0.5 to 2.0 parts of CaO; 0.3 to 1.0 part of Fe2O3; 0.1 to 0.6 part of Al2O3; 1.0 to 4.0 parts of SiO2; and less than or equal to 0.2 part of water (LOI). The invention further discloses a preparation method of the magnesium oxide for the moisture-proof fireproof cable and application of the magnesium oxide for the moisture-proof fireproof cable in the field of cables. The magnesium oxide for the moisture-proof fireproof cable has excellent moisture-proof and insulating properties, and the insulation is still greater than or equal to 1000M[omega] under the condition that the humidity is 80% RH and the time is 5 hours.
本发明提供一种防潮型防火电缆用氧化镁及其用途。防潮型防火电缆用氧化镁包括重量配比如下的各组分：MgO 95‑99份；CaO 0.5‑2.0份；FeO0.3‑1.0份；AlO0.1‑0.6份；SiO1.0‑4.0份；水(LOI)≤0.2份。本发明还公开了防潮型防火电缆用氧化镁的制备方法和防潮型防火电缆用氧化镁在电缆领域的用途。本发明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。
