Abstract

The invention provides a hydrophilic modified plant fiber cat litter material and a preparation method thereof. The preparation method comprises the following steps of (1) pretreatment, wherein a plant fiber base material is crushed, the crushed plant fiber base material is extruded and puffed, and alkalization treatment is performed by spraying alkali liquor or soaking with the alkali liquor; (2)hydrophilic modification, wherein water, an initiator, acrylic acid and a cross-linking agent are sequentially added into the pretreated plant fiber base material under the conditions of heating andstirring, heating and stirring are continued, and a reaction is performed to obtain a reaction product; and (3) post-treatment, wherein the reaction product is extruded and filtered to remove excessive moisture, and then drying and crushing are performed to obtain hydrophilic modified plant fibers. The selected plant fiber base material is subjected to hydrophilic modification through physical andchemical methods, the water absorption performance of the material is improved, and therefore the novel plant fiber cat litter material with the water absorption performance superior to that of pea dregs and soybean dregs is prepared.

Description

technical field [0001] The invention belongs to the field of pets, and in particular relates to a hydrophilic modified plant fiber cat litter material and a preparation method thereof. Background technique [0002] Cat litter was invented by Americans in 1948. After 50 years of research and development, its quality and requirements have been continuously improved. The early cat litter was mainly non-condensing cat litter, and people mainly used it to store cat feces. However, with the continuous improvement of cat litter technology, people are not limited to simple storage, so the current bentonite cat litter continues to appear. Litter, wood and paper cat litter, crystal litter, etc. Among them, the water absorption and agglomeration of bentonite cat litter are very good, and the deodorization ability is better than other cat litters. In addition, the texture of bentonite cat litter is very similar to the original sandy soil, which is more acceptable to cats, so bentonite ...
