Preparation method of aerogel composite thermal insulation material
The invention discloses a preparation method of an aerogel composite thermal insulation material, and relates to the technical field of material preparation, the preparation method of the aerogel composite thermal insulation material comprises the following steps: 1, weighing raw materials; 2, preparing an aerogel heat insulation material; step 3, preparing a refractory coating; 4, curing and forming; and 5, extruding and cooling. According to the preparation method, the wet gel felt body is soaked in the organic siloxane solution at a specific temperature, and impurity removal, aging, solvent exchange and alkylation treatment of the wet gel felt body can be synchronously realized at one time, so that the preparation period of the aerogel composite thermal insulation material is greatly shortened; meanwhile, the heat preservation performance of the aerogel composite heat preservation material can be improved by adding the heat-resistant coating, the PH adjusting time of a mixed solution can be shortened by utilizing the PH adjusting agent with the specific concentration, the preparation period of the aerogel composite heat preservation material is further shortened, and the raw materials are dried by utilizing a microwave oven, so that the raw materials can be rapidly dried under normal pressure.
本发明公开了一种气凝胶复合保温材料的制备方法，涉及材料制备技术领域，该气凝胶复合保温材料的制备方法包括以下步骤：步骤一：称取原料；步骤二：制备气凝胶绝热材料；步骤三：制备耐火涂料；步骤四：固化成型；步骤五：挤压并冷却。本发明将湿凝胶毡体浸泡在特定温度下的有机硅氧烷溶液中，可一次性同步实现湿凝胶毡体的除杂、陈化、溶剂交换及烷基化处理，从而大幅缩短了气凝胶复合保温材料的制备周期，同时加入耐热涂料可以提高气凝胶复合保温材料的保温性能，利用特定浓度的PH调节剂可以加快混合溶液PH的调节时间，进一步缩短了气凝胶复合保温材料的制备周期，利用微波炉对原料进行干燥，使原料在常压下就能快速干燥。
