| titleOfInvention | Magnetic silica aeroge and its constant pressure and dry preparation method |
| abstract | The invention discloses a kind of magnetic SiO 2 Aeroge and its constant pressure and dry preparation method, various multi-polysiloxanes are made by raw material of positive esters of silicon acis and are used as silicon source for this method, by the way that positive esters of silicon acis, magnetic nanoparticle, alcohol or ketone and base catalyst are well mixed, gel, aging are formed under stirring, then wet gel is blended, and replaced with the liquid alkane or fluoroalkane of low surface tension, and be modified using water-repelling agent, pass through natural filtration or centrifugation, finally dry, so as to obtain various magnetic SiO 2 Aerogel powder.The method of the present invention can realize magnetic SiO 2 The continuous production of aeroge, with short production cycle, cost is low, energy-conserving and environment-protective, and obtained magnetic SiO 2 Aeroge is nano-porous structure, and with ideal density, thermal conductivity, specific surface area etc., while heat preservation and insulation is met, imparts aeroge magnetic function. |
