Reaction kettle and preparation method of silicon dioxide aerogel heat insulation composite material
The invention discloses a reaction kettle and a preparation method of a silicon dioxide aerogel heat insulation composite material, wherein the preparation method comprises the following steps: providing the reaction kettle, wherein the reaction kettle comprises a kettle body and a plurality of ultrasonic device groups, the kettle body is provided with a reaction cavity, the plurality of ultrasonic device groups are arranged on the side wall of the reaction cavity along the vertical direction, each ultrasonic device group comprises a plurality of ultrasonic transducers, and the plurality of ultrasonic transducers are arranged at intervals along the circumferential direction of the reaction cavity; providing a wet gel composite material subjected to aging treatment; placing the wet gel composite material in the reaction cavity, adding a silsesquioxane solution and an acid solution, and carrying out annular ultrasonic cavitation treatment to enable a liquid in the reaction cavity to be emulsified and react to obtain a modified material; and drying the modified material to obtain the silicon dioxide aerogel heat insulation composite material. The modification speed is high, the quality of the obtained silicon dioxide aerogel heat insulation composite material is good, the consumed solvent amount is greatly reduced, and the production cost is reduced.
本发明公开一种反应釜及二氧化硅气凝胶隔热复合材料的制备方法，包括以下步骤：提供反应釜，所述反应釜包括釜体和多个超声器组，所述釜体具有反应腔，多个所述超声器组沿上下方向设于所述反应腔的侧壁，各所述超声器组包括多个超声换能器，多个所述超声换能器沿所述反应腔的周向间隔设置；提供经老化处理过的湿凝胶复合材料；将所述湿凝胶复合材料置于所述反应腔中，加入倍半硅氧烷溶液和酸溶液，环形超声空化处理，以使得所述反应腔中的液体乳化并发生反应，得到改性材料；对所述改性材料进行干燥，得到二氧化硅气凝胶隔热复合材料。本发明改性速度快且得到的二氧化硅气凝胶隔热复合材料的品质较好，且大大减少了耗费的溶剂量，降低了生产成本。
