Description
Technical Field
The application relates to the field of pet supplies, in particular to a pet urinal pad with a deodorization function and a preparation method thereof.
Background
With the improvement of living standard of people, more and more people also start to raise pets, and how to solve the defecation of the pets in the process of raising the pets also becomes a headache problem. Especially for animals with large excretion such as pet dogs, the utility model causes great inconvenience to the indoor environment, generates large peculiar smell and affects the indoor living environment sanitation. In order to improve the household environment, many pet raising personnel purchase a pet toilet or a pet urinal pad at home, and the pet urinal pad can absorb urine excreted by animals, so that the household sanitary cleaning burden of the raising personnel is reduced.
The pet urinal pad commonly used in the market at present does not generally have a deodorization function, and most of the pet urinal pads with the deodorization function adopt materials such as activated carbon and the like as deodorizers, and the activated carbon can adsorb some odor components in animal excrement, so that the odor generated by the animal excrement is reduced, and the living environmental sanitation is improved.
However, there are many disadvantages in using activated carbon as a deodorant, the activated carbon has a deodorizing effect by adsorbing odor components in animal excreta, but the activated carbon has a weak adsorption capability to odor and weak adsorption at the same time because of its limited pore size; on the other hand, the odor generated by pet excrement is mostly odor components mainly comprising ammonia gas, hydrogen sulfide and some volatile organic compounds, the adsorption performance of the activated carbon to the substances is poor, and the pet urinal pad added with the activated carbon deodorant cannot play a good odor adsorption role, so that the improvement effect of the indoor environmental sanitation of the pet urinal pad is limited, and the effect of comprehensively removing the odor cannot be achieved.
