Abstract

The invention provides a light aerogel material. Preparation raw materials of the material include a high polymer material and clay. The light aerogel material is a light strong-adsorptivity materialprepared by mixing clay, a hydrophilic high polymer material and other possibly added inorganic raw materials, then using water as a medium to perform high-speed stirring to reach a sticky state and adopting a freeze-drying method. The prepared light aerogel material has a nanoscale and micron-scale structure, so that the material has very large water absorbing capability and very high water absorbing rate. The light aerogel material can serve as cat litter, and the water absorbing capability and water absorbing rate of the material are higher than those of like products. In addition, the light aerogel material is controllable in density, so that the density of the material can meet the demands on different adsorption occasions including cat litter. Furthermore, the material can form an irregular structure with a rough surface through crushing and can also form various special shapes through freeze formation of dies.

Description

technical field [0001] The invention relates to a lightweight airgel material and a preparation method thereof, more specifically, to a lightweight airgel material with high water absorption rate and fast water absorption speed and a preparation method thereof. Background technique [0002] Cat litter, commonly known as pet toilet paper, is a daily necessities for families with regular pets. In addition, cat litter is also used in pet shops and pet breeding farms. Cat litter is a pet product with huge consumption. It can absorb waste such as pet urine and feces, and prevent odor from spilling out. Its importance in the entire pet market is second only to cat food. When using, pour the cat litter into the cat litter box, spread it 7-10cm thick, and then it can be used by the cat. Put it into the trash can, and the remaining cat litter in the cat litter box is still clean and can be used continuously. [0003] At present, common cat litter products include bentonite montmori...
