Description
Technical Field
The invention belongs to the technical field of cat litter, and particularly relates to non-caking cat litter and a preparation method thereof.
Background
With the improvement of the quality of life of people, the pet breeding is favored by more and more people, but the problem of environmental pollution caused by pet excrement in the process of breeding the pet is solved, and the great attention of people is paid.
The cat litter is a substance used for burying excrement and urine and controlling odor for cats kept by a feeder, has good water absorption and is a necessary product for families for keeping pet cats. The cat urine contains about 95% of water and about 5% of ammonia, and can generate serious odor and bacteria if not cleaned in time after the cat excretes.
The existing cat litter is basically divided into two types, one type is caking type cat litter, and the other type is non-caking type cat litter. The caking cat litter, particularly the cat litter prepared from sodium bentonite, can form cat urine into a mass after the cat urinates, so that the cat urine is convenient to clean, but the cat litter has large dust and poor deodorization capability; in the prior art, some environment-friendly caked cat litters prepared by using crop straws, light-density cellulose, pine trees and the like have good water absorption effect, can be directly thrown into a closestool, are easy to breed bacteria, have poor caked strength, and are easy to scatter by a cat after excretion, thus bringing inconvenience to the collection; the development of non-caking type cat litter is about to be earlier than caking type cat litter to clay cat litter that does not agglomerate is given first place to, and this kind of cat litter brings certain inconvenience for picking up owing to can not caking, however, this kind of cat litter water saturation time is long, can excrete the back at the cat and absorb cat urine rapidly, with cat litter moisture dry suction sclerosis, the water saturation time extension, then the live time of cat litter also prolongs, this can be for needing to use the cat litter for a long time and inconvenient in time the raiser who cleans up brings the convenience, saves the resource. However, the conventional non-caking cat litter has a short water saturation time and causes a serious odor when the cat litter is not cleaned in time after excretion. Therefore, the cat litter with short water absorption time, long water saturation time and long service time is of great significance for feeding cats.
