High-mechanical-strength aerogel thermal insulation material and preparation method thereof
The invention discloses a high-mechanical-strength aerogel thermal insulation material and a preparation method thereof. The high-mechanical-strength oxide aerogel thermal insulation material is prepared through fiber modification, sol preparation and dipping, aging and gel modification, supercritical drying and high-temperature sintering. A binder solution is adopted to carry out liquid phase modification on wet gel, a binder dispersion liquid is adopted to modify a fiber reinforced phase, and an aerogel matrix and a composite material thereof are reinforced through physical and chemical reactions, so that the mechanical properties of the aerogel thermal insulation material are remarkably improved.
本发明公开了一种高机械强度气凝胶隔热材料及其制备方法，本发明通过纤维改性、溶胶配制与浸渍、老化与凝胶改性、超临界干燥、高温烧结制备得到高机械强度的氧化物气凝胶隔热材料。采用粘结剂溶液对湿凝胶进行液相改性，采用粘结剂分散液对纤维增强相进行改性，通过物理与化学反应对气凝胶基体及其复合材料进行强化，显著提高气凝胶隔热材料的力学性能。
