Inorganic microcrystalline electret material and preparation method thereof
The invention belongs to the technical field of electret materials, and particularly relates to an inorganic microcrystal electret material and a preparation method thereof. The inorganic microcrystal electret material is prepared from the following raw materials in percentage by weight: 35%-45% of silicon dioxide, 15%-25% of zinc oxide, 15%-25% of diboron trioxide, 10%-15% of magnesium oxide and the balance performance modifier, the preparation method comprises the following steps: mixing silicon dioxide, zinc oxide, diboron trioxide and magnesium oxide, melting at a high temperature to prepare a composite powder material which has multi-component compounding, microcrystalline structure, single and stable energy trap mechanism and positive and negative symmetrical electricity standing properties, preparing the composite powder material and natural wax or rosin in a molten state into a sol body, so that the sol body can be more conveniently coated on the polished surface of monocrystalline silicon, and then the inorganic microcrystalline electret material has a higher dielectric constant by selecting a specific heating rate and a heating stage value.
本发明属于驻极体材料技术领域，具体涉及一种无机微晶驻极体材料及其制备方法，其原材料组成及相应重量百分比为：二氧化硅35％‑45％、氧化锌15％‑25％、三氧化二硼15％‑25％、氧化镁10％‑15％、其余为性能调节剂，选取二氧化硅、氧化锌、三氧化二硼和氧化镁进行混合，经高温熔制，制备出复合粉体材料，具有多组分复合化、微晶结构、单一稳定的能阱机制、正负对称的驻电性能，将复合粉体材料与熔融状态的天然蜡或松香一同配置成溶胶体，更加便于涂覆于单晶硅的抛光面上，再经特定升温速率及升温阶段值的选取，使得无机微晶驻极体材料具有较高的介电常数。
