Description
Technical Field
The invention relates to the field of cat litter, and particularly relates to environment-friendly composite biological enzyme deodorant cat litter and a preparation method thereof.
Background
The domestic and foreign cat litter mainly comprises diatomite cat litter, bean curd cat litter, mixed cat litter and the like. At present, bentonite cat litter is generally adopted, diatomite, organic matter base material and organic adhesive are generally adopted to be mixed and granulated to prepare the cat litter, when the excrement or urine of a cat is contacted with the cat litter, the cat litter which is contacted with the excrement or urine forms an integrated sphere with the excrement or urine due to the moisture absorption effect of the cat litter, the cat litter which is not stained with the excrement or urine is not polluted, and the cat litter can be continuously used, so that the excrement and urine of small animals are very easy to clean. Although the bentonite cat litter is low in manufacturing cost, the bentonite cat litter has large dust and has hidden environmental protection hazards. The soybean curd cat litter solves the problem of dust of bentonite cat litter to a certain extent, is environment-friendly and easy to degrade, but the main raw material of the soybean curd cat litter is soybean curd residue which is prepared from food, so that grains are wasted, and the cost is high.
The urine of cats contains felinine (Felnine) and enzyme protein (Cauxin), which are essential components for the unique odor of cat urine, and these substances form a special strong odor when being discharged from the body and contacted with the air. Because time and condition restriction, the cat litter after using can't in time clear up in the very first time under most conditions, and the excrement of cat is not cleared up for a long time, can lead to the foul smell, and the bacterium also can constantly breed. When the cat litter is polluted, only the polluted local agglomerated cat litter observed by naked eyes is eradicated, the remaining part of the cat litter is difficult to ensure to be not polluted, the polluted cat litter cannot be completely cleaned, peculiar smell still remains, bacteria are bred, and the living environment is polluted.
In the prior art, an adsorptive substance is usually adopted to adsorb odor, or other raw materials with fresh odor are adopted to cover the odor, so that the effect of controlling the odor to diffuse into the environment is achieved. For example, the Chinese patent with the application number of 201610189158.7 discloses a safflower seed composite cat litter and a preparation method thereof, and the raw materials comprise: safflower seed particles, traditional Chinese medicine powder, water-absorbent resin particles, active carbon particles, an alkaline modifier, a binder and a proper amount of water, and the technical effect of deodorization is achieved through the traditional Chinese medicine particles and the adsorptive particles. However, odor cannot be fundamentally prevented by the adsorption and masking methods, the adsorption effect gradually weakens with the prolonging of the service time, the masking effect also becomes worse, and the methods cannot prevent the breeding of bacteria and easily cause health hidden troubles.
