The invention provides an aerogel material processing device, and relates to the technical field of aerogel processing. The aerogel material processing device comprises a glue tank, wherein a base is mounted at the lower end of the glue tank, and sol is arranged in the glue tank and contains a solvent A; an evaporating tank which is mounted on the right side of a gas filling box; a modification tank, wherein the left end of the modification tank is connected with the right end of a second group of gas filling box; a drying tank which is located on the right side of the modification tank, wherein aerogel enters the evaporation tank to be subjected to azeotropic distillation with an entrainer B, when evaporation is finished, a gel composite material passing through the evaporation tank enters the modification tank, a modifier in the modification tank conducts hydrophobic modification on hydroxyl in the gel composite material, and a hydrophobic gel composite material is obtained, the aerogel water resistance and permeability are improved, the solvent is replaced through azeotropic distillation, so that the replacement is more efficient and thorough, and the problem of poor water permeability resistance of the aerogel is solved; and in the discharging process, an air rod is shortened, a material collecting wheel can be stably placed on the ground, and the problem that discharging is troublesome is solved.
Description
technical field [0001] The invention relates to the technical field of airgel processing, in particular to an airgel material processing device. Background technique [0002] Airgel is an ultra-light and high-porosity mesoporous material obtained by replacing the liquid in the pores of the wet gel with gas without the structure collapsing. The supercritical method utilizes the characteristics of supercritical fluids such as no surface tension, high diffusivity, and high solubility to effectively avoid the collapse of the gel skeleton during the drying process, and at the same time realize the separation of the solvent and the gel skeleton, and can prepare airgel products with excellent performance , is the most commonly used standard method for preparing high-quality aerogels. However, the supercritical method involves high-temperature and high-pressure use of special equipment such as high-pressure containers and dangerous chemicals. At the same time, materials need to be ...
