Preparation method of aerogel dispersible particles, prepared aerogel particles and application
The invention provides a preparation method of aerogel dispersible particles, which comprises the steps of firstly, preparing aerogel powder into a master batch, wherein the step includes the sub-steps of 1, slowly adding a filler 1 into deionized water, and uniformly mixing in a stirrer; 2, adding a filler 2 into the mixture obtained in the step 1; 3, slowly adding a filler 3 into the mixture obtained in the step 2, uniformly mixing in the stirrer, and sealing for later use; and 4, taking aerogel powder, adding a small amount of the aerogel powder into the solution obtained in the step 2 for multiple times, stirring, stopping when the intermediate temperature rises, continuously adding the aerogel after cooling, stirring, and finally, completely mixing all the aerogel powder with the components obtained in the step 3 to obtain a master batch; and feeding the master batch prepared according to the formula into a mixer through a feeder to be mixed, and and then drying. The invention also provides aerogel dispersible particles and application thereof. The method has the advantages that the process is simple and convenient to popularize; and the high-content aerogel dispersed particles prepared by the method are good in dispersity, uniform in particle size, not easy to break and free of dust in use.
本发明提供一种气凝胶可分散颗粒的制备方法，首先将气凝胶粉末制作成母料，包括：一、向去离子水中缓慢加入填料1，在搅拌器中混合均匀；二、向步骤一中加入填料2；三、向混合好的步骤二中缓慢加入填料3，在搅拌器中混合均匀，密封待用；四、取气凝胶粉，少量多次向步骤二溶液种加入气凝胶粉进行搅拌，中间温度升高应停下待降温后继续添加气凝胶，搅拌，最终，将气凝胶粉全部与步骤三的组分完全混合，成母料；将上述配方做好的母料经过送料器送入混料机中混料后，烘干。本发明还提供了一种气凝胶可分散颗粒及应用。本发明的优点为：工艺简单，便于普及；且本方法制备的高含量气凝胶分散粒分散性好、颗粒大小均匀、不易碎、使用无粉尘。
