Problems solved by technology

Traditional non-agglomerating cat litter is limited to providing a place for cats to excrete, but its coagulation and water absorption are poor, and it can only be used once or a limited number of times, so the entire cat litter needs to be replaced

Abstract

The present disclosure provides a lightweight aerogel material including a polymer and clay. The lightweight aerogel material in the present disclosure may be a lightweight and strong absorbent material prepared by mixing the clay, hydrophilic polymer, and other inorganic raw materials that may be added, adding water to the mixture as a medium, stirring the mixture at a high speed to become viscous, and lyophilizing the mixture. The lightweight aerogel material prepared in this manner may have a micron-sized and nano-sized pores, which contributes to the high water absorbency and water absorption rate. When the lightweight aerogel material is used as cat litter, the water absorbency and water absorption rate of the cat litter may be much higher than the similar products. Furthermore, the density of the lightweight aerogel material in the present disclosure is controllable, which may meet the needs for different applications including the cat litter. Moreover, the lightweight aerogel material may be crushed to obtain irregular structures with rough surfaces, or may be formed into various special shapes through mold freezing.

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...
