Description
Technical Field
The invention belongs to the technical field of pet products, and particularly relates to bentonite-based composite cat litter and a preparation method thereof.
Background
Cat litter is a type of product that is needed in pet products and, because it is used to treat pet waste, must absorb water quickly and have excellent wrappability. With the improvement of understanding degree of the habit of the cat and the standard of the environmental sanitation requirement, various types of cat litter continuously emerge, and common cat litter products in the market at present comprise bentonite cat litter, crystal cat litter, sawdust cat litter, paper scrap cat litter, bean curd cat litter and the like.
The bentonite cat litter can better simulate a desert environment, has the foot feel closest to the original nature and most accords with the original nature of cats, so that the bentonite cat litter is the favorite cat litter type of cats; in particular, sodium montmorillonite is superior to other types of cat litter in its strong adsorption, extraordinary swelling and encapsulation properties.
Although the bentonite cat litter has strong adsorbability, can completely absorb moisture and urine in excrement and then coagulate into a large hard mass, the bentonite cat litter does not have antibacterial and deodorant properties, can not inhibit breeding of bacteria in large and small excrements of cats and can not cover the taste of the excrements of the cats.
In order to solve the above problems, deodorizing components such as perfume, porous materials (including diatomaceous earth, activated carbon, sepiolite), and the like are generally additionally added to the existing bentonite cat litter.
For example, the chinese patent with the publication number of CN106718976B discloses a method for preparing activated carbon cat litter, which contains activated carbon, bentonite, medical stone and tourmaline, wherein the activated carbon has strong adsorption capacity and also has the functions of decoloring, deodorizing, disinfecting and sterilizing; maifanitum is effective in treating skin ulcer, dermatoses, and fungi; tourmaline has the functions of generating negative ions, radiating far infrared rays, disinfecting, sterilizing and disinfecting.
However, the existing deodorizing components used in the cat litter have the following disadvantages: (1) the perfume can cover the peculiar smell of excrement, but only performs smell deception, and the ammonia nitrogen harmful molecules still exist; (2) the adsorption of the porous material is non-selective, and other gases are continuously adsorbed in the preparation, transportation and storage processes of the cat litter, so that the real deodorization efficiency is low. Therefore, there is a need to develop deodorizing compositions that can be used in cat litter and that specifically deodorize cat pet waste.
Disclosure of Invention
The invention aims to provide bentonite-based composite cat litter and a preparation method thereof.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the bentonite-based composite cat litter comprises raw materials of bentonite and a deodorizing component, wherein the deodorizing component comprises at least one of calcium superphosphate, calcium monohydrogen phosphate and straw powder.
In the invention, calcium superphosphate, calcium monohydrogen phosphate or rice straw powder (obtained by crushing straw stalks into 800 meshes of 600 meshes) is adopted to replace the traditional porous adsorption material (simultaneously adsorbing ammonia gas, formaldehyde, carbon dioxide and other gases) as the cat litter deodorization component, compared with the nonselective physical adsorption of the porous adsorption material to ammonia gas, formaldehyde, carbon dioxide, water vapor and other gases, in the deodorization component of the invention, the calcium superphosphate, the calcium monohydrogen phosphate and the straw powder can specifically perform ammoniation or super-chemical reaction with ammonia nitrogen odor substances (including ammonia gas) in cat pet excrement to generate superphosphorized ammonia or ammonium sulfide, thereby realizing the selective anchoring and conversion of the ammonia nitrogen odor substances in the cat pet excrement, preventing the ammonia gas and other odor substances from escaping, achieving the complete chemical deodorization effect, having good deodorization effect and not influencing the deodorization effect after being placed for a long time, the deodorization time is long; meanwhile, the reaction product is not only harmless to the health of cats, but also can be used as a fertilizer, thereby achieving two purposes at one stroke.
The deodorizing component of the present invention is preferably at least two of calcium superphosphate, calcium monohydrogen phosphate and rice straw powder. The calcium superphosphate and the calcium monohydrogen phosphate are main components of the phosphate fertilizer, and although free acid and the calcium monohydrogen phosphate contained in the calcium superphosphate can both fix ammonia and generate ammoniated calcium superphosphate, the reaction activity of the calcium monohydrogen phosphate and ammonia gas is higher, and the reaction amount of the calcium superphosphate and the ammonia gas is larger, so that the gradient reaction can be obtained by combining the calcium superphosphate and the calcium monohydrogen phosphate, namely, the two-hand grasping of instantaneous and rapid ammonia capture and long-acting ammonia laying. The rice straw powder can react with ammonia gas to generate ammonium sulfate, and any two of calcium superphosphate, calcium monohydrogen phosphate and the rice straw powder are used in combination, so that the continuous conversion of pet excrement of cats can be realized; moreover, the straw powder has the functions of micro-pore adsorption and fungus growth inhibition, is more favorable for anchoring ammonia gas and improving the adsorption performance of bentonite.
Preferably, in the bentonite-based composite cat litter, the deodorizing component comprises 10-20 parts by weight of calcium superphosphate, 8-20 parts by weight of calcium monohydrogen phosphate and 8-20 parts by weight of straw powder; the particle size of the deodorization component is between 200 meshes and 800 meshes.
The calcium superphosphate, the calcium monohydrogen phosphate and the straw powder are used in combination, so that the deodorizing effect of the cat litter is optimal. The grain diameter of the deodorization component is equal to or smaller than that of the bentonite, so that the influence of the deodorization component on bentonite granulation is avoided; further, the smaller the particle size of the deodorizing component is, the larger the specific surface area is, and the deodorizing effect is more excellent.
In the bentonite-based composite cat litter, the raw materials also comprise anion powder. The anion powder can produce negative oxygen ions, and the negative oxygen ions have the functions of bacteriostasis and formaldehyde removal, can purify air in the space around the cat litter, and improve the immunity of people and cats.
Preferably, in the bentonite-based composite cat litter, the anion powder comprises at least one of tourmaline powder, hexacyclic ring stone powder, titanium dioxide phosphate and fullerene. The tourmaline powder, the hexacyclic stone powder, the titanium dioxide phosphate and the fullerene have excellent negative ion release functions, wherein the tourmaline powder and the hexacyclic stone powder have the best negative ion release capability, and the titanium dioxide phosphate and the fullerene have excitation effects on the tourmaline powder and the hexacyclic stone powder. Therefore, the anion powder of the present invention preferably includes at least one of tourmaline powder or hexacyclic stone powder, and more preferably at least one of titanium dioxide phosphate and fullerene is added.
Preferably, in the bentonite-based composite cat litter, the anion powder contains 15-25 parts of tourmaline powder, 10-20 parts of hexacyclic ring stone powder, 3-5 parts of titanium dioxide phosphate and 2-5 parts of fullerene in parts by weight;
the particle size of the anion powder is between 1000-1500 meshes.
