Abstract
The invention discloses a high-efficiency deodorizing high-performance mixed cat litter and a preparation method thereof, belonging to the technical field of cat litter, and the high-efficiency deodorizing high-performance mixed cat litter is prepared from the following raw materials in parts by weight: 3-7 parts of bean curd cat litter; 3-7 parts of bentonite cat litter; 3-7 parts of high-efficiency deodorizing zeolite cat litter, which can be realized, has good caking property, good water absorption, good water-soluble collapsibility, strong odor masking and deodorizing power, less dust, moderate specific gravity, difficult carrying of cats out of a cat basin and good mildew resistance.
Description
Technical Field
The invention relates to the technical field of cat litter, in particular to high-performance mixed cat litter capable of efficiently deodorizing and a preparation method thereof.
Background
With the acceleration of the process of Chinese urbanization, the development of the pet industry in China is rapid, wherein pet cats are increasingly popular with young people with busy urban work due to the characteristics of small exercise amount, fondness of solitary and the like, and related industries are explosively increased in recent years. The cat litter is used as a pet cat excretion place, is a necessity for closed cat raising in cities, and is also a pet product with the largest daily consumption. At present, cat litter in the market is produced in various types and has advantages and disadvantages, and evaluation criteria are generally considered from four aspects of condensation force, water absorption, odor masking force and dust amount.
The bentonite cat litter on the market at present has good water absorption and caking property and the lowest price and cost, but the dust is extremely large, so that the dust is easily accumulated in room furniture, the long-time use of the cat litter can cause certain influence on the respiratory tract of the cat, the specific gravity is too large, and the cleaning is laborious. The zeolite cat litter has strong deodorization capacity, moderate specific gravity, is difficult to plane out of a cat basin by a cat, has no water absorption, needs to be matched with a water absorption gasket for use, and has poor wrapping capacity on loose excrement. The bean curd cat litter has the advantages of no harm to eating, small dust, good water absorption and agglomeration effect and good foot feel, and has the defects of being too light and easy to dig out of a cat basin by a cat, and simultaneously, because the bean dregs contain protein, the bean dregs are easy to mildew and deteriorate in a humid environment, and bacteria are bred quickly. Therefore, the cat litter with good water absorption and caking property, low dust and effective deodorization is not capable of being applied to a single cat litter at the same time, but can be applied to make up for deficiencies only by compounding modified cat litters of different types.
The invention aims to provide high-performance mixed cat litter with good water absorption and caking property, low dust and high-efficiency deodorization.
Disclosure of Invention
1. Technical problem to be solved
Aiming at the problems in the prior art, the invention aims to provide the high-performance mixed cat litter for efficient deodorization and the preparation method thereof, and the cat litter has the advantages of good water absorption and caking property, low dust and efficient deodorization.
2. Technical scheme
In order to solve the above problems, the present invention adopts the following technical solutions.
The high-performance mixed cat litter with high efficiency deodorization is prepared from the following raw materials in parts by weight:
3-7 parts of bean curd cat litter;
3-7 parts of bentonite cat litter;
3-7 parts of high-efficiency deodorizing zeolite cat litter.
Further, the bean curd cat litter is prepared from the following raw materials in parts by weight:
25-35 parts of bean dregs;
25-35 parts of stone powder;
5-15 parts of poplar powder;
0.5 to 0.8 portion of nano zinc oxide powder;
5-15 parts of corn flour;
15-25 parts of corn starch;
1-3 parts of pregelatinized starch;
1-3 parts of rubber powder;
1-3 parts of guar gum;
0.05 to 0.2 portion of nano sulfur solution;
0.25 to 0.5 portion of milk essence.
Further, the bentonite cat litter is prepared from the following raw materials in parts by weight:
80-90 parts of calcium bentonite;
2-4 parts of sodium carbonate;
2-3 parts of 4A zeolite;
2-5 parts of activated carbon;
0.55 to 1.1 portions of corn oil;
0.375 to 0.75 portion of soybean oil;
0.375 to 0.75 portion of palm oil;
1-3 parts of glycerol;
5-8 parts of calcium carbonate.
Further, the high-efficiency deodorizing zeolite cat litter is prepared from the following raw materials in parts by weight:
85-91 parts of zeolite particles;
0.3 to 0.5 portion of waterborne polyurethane;
7-13 parts of deionized water;
0.3-0.5 part of soybean oil-based ethyl morpholinium ethyl sulfate;
0.7 to 1.2 parts of 2,2' -dichlorodiethyl ether.
Furthermore, stone powder and poplar wood powder in the bean curd cat litter can be completely replaced by bean dregs;
corn starch in the bean curd cat litter can be replaced by cassava starch, and the pregelatinized starch can be replaced by oil powder;
the glycerol in bentonite cat litter can be replaced with propylene glycol.
A preparation method of high-performance mixed cat litter with high-efficiency deodorization comprises the following steps:
step 1: adding the bean curd cat litter, the bentonite cat litter and the high-efficiency deodorizing zeolite cat litter into three vibrating screens respectively, wherein the bottoms of the vibrating screens are guided to the same charging basket together;
step 2: and adjusting the vibration frequency of each vibrating screen to ensure that the tofu cat litter, the bentonite cat litter and the high-efficiency deodorizing zeolite cat litter are respectively 7:3, uniformly mixing the components in parts by weight;
and step 3: and (5) obtaining the high-performance mixed cat litter with high efficiency deodorization in the charging barrel.
Further, the bean curd cat litter is prepared by the following steps:
(1) Weighing the bean dregs, the stone powder, the poplar powder and the nano zinc oxide powder according to the mass parts, and putting the bean dregs, the stone powder, the poplar powder and the nano zinc oxide powder into a first ingredient mixing and stirring device for mixing and stirring for 13-15 minutes;
