The aerogel material is prepared by fiber-reinforced technology, which is prepared by impregnating sol, gel, solvent replacement and supercritical drying. It has the characteristics of low thermal conductivity, high hydrophobicity, good shock absorption and natural fire resistance. At the same time, flexible or rigid inorganic fiber reinforced aerogel materials can be produced according to demand, which are used in thermal insulation and flame retardant of new energy commercial vehicles, thermal insulation and energy saving and anti-corrosion protection of oil pipelines, thermal insulation and energy saving of heating pipelines, thermal insulation and fire prevention of building exterior walls, thermoelectric Thermal insulation of high temperature pipelines and equipment in the field, cold insulation of pipelines and equipment in deep fields such as LNG, etc.
