Description

Technical Field

[0001] The invention relates to the technical field of pet breeding, in particular to a method for preparing a cat litter deodorant. Background Art

[0002] Different types of cat litter have different water absorption and clumping effects, which directly affect the deodorization effect. For example, bentonite cat litter has a good clumping effect, but it is dusty; tofu cat litter is environmentally friendly, but it is easy to get wet. Humid weather will make cat litter more likely to stink, because high humidity will accelerate the growth of bacteria and the release of ammonia. In addition, poor ventilation will also aggravate the accumulation of odor. The cat's excretion habits will also affect the smell of the cat litter. If the cat does not develop good excretion habits, such as defecating on the edge of the cat litter box, it will cause the cat litter to fail to effectively wrap the feces, thereby increasing the odor.

[0003] There are a variety of cat litter deodorizing products on the market, but not all products are suitable for every type of cat litter. For example, some deodorizers work well with some types of cat litter, but may destroy the clumping effect of other types of cat litter. Even if you use the best cat litter and deodorizing products, odors in the cat litter box will quickly accumulate if feces and urine clumps are not removed in time. Cat litter deodorization is a common problem, especially for families with multiple cats or families with small living spaces.

[0004] Therefore, for most families, an efficient, long-lasting, broad-spectrum, non-irritating cat litter deodorizer is undoubtedly essential.

[0005] The present invention just fills this gap. This cat litter deodorant has the characteristics of strong deodorizing activity, fast speed, and long duration. The induced zinc ions have the functions of decomposition, oxidation, catalysis, complexation, reduction, etc. The deodorant acts on the reactants, changes the reaction pathway, and thus reduces the activation energy of the odor factor reaction. Moreover, the zinc ions in this deodorant can not only react with hydrogen sulfide and ammonia in the odor, but also react with -NH, -COOH, -SH, etc. in cat litter bacteria, thereby destroying the cell structure of the bacteria, preventing their reproduction, and achieving the effect of killing bacteria and mold; the cat litter deodorant shows excellent decomposition and adsorption properties, and can quickly decompose the hydrogen sulfide, ammonia, methyl mercaptan and other odor molecular structures in cat litter and cat feces, thereby reducing the toxicity of pollutants and destroying their chemical structure. Summary of the invention

[0006] The object of the present invention is to provide a method for preparing a cat litter deodorant to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The invention provides a method for preparing a cat litter deodorant, comprising the following steps:

[0009] Add sodium carboxymethyl cellulose to amino acid chelated zinc S01, heat to 50°C to 90°C, react for 2h to 5h, so that the sodium ions in the sodium carboxymethyl cellulose and the zinc ions in the amino acid chelated zinc undergo a replacement reaction to generate a carboxymethyl cellulose zinc precursor solution, and cool to obtain a precursor solution;

[0010] Add diammonium hydrogen phosphate, wheat dextrin, plant extract, and deionized water to the S02 precursor solution, stir for 2 h to 5 h at a temperature of 65 ° C to 90 ° C, and cool to obtain a cat litter deodorant;

[0011] Furthermore, in step S01, the mass ratio of amino acid chelated zinc to sodium carboxymethyl cellulose is 100:1 to 50:1.

[0012] Furthermore, in step S02, the mass ratio of the precursor solution to diammonium hydrogen phosphate is 50:1 to 10:1.

[0013] Furthermore, in step S02, the mass ratio of diammonium hydrogen phosphate, wheat dextrin, plant extract, and deionized water is 1-10: 0.1-1: 0.1-0.5: 88.5-98.8.

[0014] Furthermore, the plant extract in step S02 is one or more of mugwort plant extract and lemon plant extract.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Zinc carboxymethyl cellulose (Zn-CMC) is a composite material that combines zinc with carboxymethyl cellulose. It has the characteristics of both carboxymethyl cellulose and zinc. At the same time, zinc has a broad-spectrum antibacterial activity and can inhibit the growth of a variety of bacteria. Zinc carboxymethyl cellulose can release zinc ions to exert deodorizing, antibacterial and antibacterial effects, and is used to eliminate the spread of harmful odorous substances caused by bacterial growth.

[0017] In step S01 of the present invention, sodium ions in sodium carboxymethyl cellulose and zinc ions in amino acid chelated zinc undergo a replacement reaction, so that carboxymethyl cellulose and zinc ions can be combined through a new coordination bond to form a new and more stable chelate. The role of zinc ions can be better exerted through this new combination mode. The interaction between diammonium hydrogen phosphate, wheat dextrin, plant extract and zinc carboxymethyl cellulose added in the present invention can be more fully and evenly dispersed in the product, so that the product has the functions of rapid adsorption and deodorization and is long-lasting. The current related products on the market only have simple deodorization, and the deodorization effect is poor and easy to recur. The present invention not only has the effect of rapid deodorization, but also has the effect of long-lasting deodorization, and the overall effect will be better.

[0018] The cat litter deodorant of the present invention can quickly absorb and inhibit harmful malodorous substances such as NH3, H2S, amines, etc., quickly eliminate the odor of cat feces and garbage, inhibit bacterial growth, purify the environment, and reduce diseases. This product is actually non-toxic, has a long-lasting deodorizing effect, has no irritation to the mucous membrane, can form a breathable film, and protect the family space environment for a long time. It is a broad-spectrum, high-efficiency new cat litter deodorant. DETAILED DESCRIPTION

The olfactory test method is a method for evaluating the odor intensity and suitability based on human sense of smell, and determining the characteristic parameters of malodor, including olfactory threshold or concentration, and sensory intensity. A 10-person olfactory test team was set up, which was 15-50 years old, non-smokers with normal sense of smell. The effect evaluation index of the cat litter with obvious odor after being treated with the cat litter deodorant prepared in Examples 1-5 was divided into five indicators: significant 4-5 points, good 3-4 points, general 2-3 points, poor 1-2 points, and invalid 0 points. There were seven groups in total, and the average score of each group was statistically averaged, that is, the best was 5 points and the worst was 0 points. After the test group was evaluated, the evaluation index of more than 5 people could be used as the test conclusion, otherwise it was re-evaluated. The specific results are shown in Table 1 below.

[0048] Table 1 Olfactory sensory evaluation results of simulated cat litter deodorant test

[0049]

[0050] It can be seen from the data in Table 1 that the deodorization evaluation results of the cat litter deodorizers prepared in Examples 1-4 are average, and Example 5 has the best effect, which can quickly and efficiently deodorize the odorous cat litter effectively.

[0051] Test Example 2

[0052] Select 5 enclosed spaces, each with a size of 2m 3, a bucket of cat litter with malodor was placed in each space, each bucket of cat litter weighed 8kg, the indoor temperature was controlled at 40-45°C, 5 spaces were selected as the deodorization test of the cat litter deodorant prepared in Examples 1-5, and the cat litter deodorant was directly sprayed on the cat litter; after the cat litter deodorant was sprayed, the ammonia, hydrogen sulfide concentration, methyl mercaptan concentration, and methyl sulfide concentration in the room were detected every 5 days, and the removal rates of ammonia concentration, hydrogen sulfide concentration, and odor concentration were calculated respectively with the blank room as the control, and the monitoring time was 30 days. The specific results are shown in Table 2 below. The detection methods used include GB / T14678-1993 Air Quality-Determination of Hydrogen Sulfide, Methyl Mercaptan, and Methyl Sulfide-Gas Chromatography, GB / T14675-1999 Air Quality-Determination of Malodor-Three-Point Comparison Stink Bag Method.

[0053] Table 2 Results of simulated cat litter deodorant test

[0054]

[0055] It can be seen from the data in Table 2 that the cat litter deodorizers prepared in Examples 1-4 have average deodorizing effects, while Example 5 has the best effect and can quickly and efficiently deodorize and remove odorous cat litter.

[0056] The cat litter deodorant prepared in Comparative Examples 1-5 was tested, and the results were as follows:

[0057] Test Example 3

[0058] The deodorizing effect was evaluated by olfactory test. The olfactory test method is a method for evaluating the intensity and suitability of odor based on human sense of smell, and determining the characteristic parameters of malodor, including olfactory threshold or concentration, and sensory intensity. A 10-person olfactory test team was established, which was 15-50 years old, non-smokers, and had normal sense of smell. The cat litter with obvious odor was treated with the cat litter deodorant prepared in comparative examples 1-5. The effect evaluation index was divided into five indicators: significant 4-5 points, good 3-4 points, general 2-3 points, poor 1-2 points, and invalid 0 points. There were seven groups in total, and the average score of each group was statistically averaged, that is, the best was 5 points and the worst was 0 points. After the test group was evaluated, the evaluation index of more than 5 people could be used as the test conclusion, otherwise it would be re-evaluated. The specific results are shown in Table 3 below.

[0059] Table 3 Olfactory sensory evaluation results of simulated cat litter deodorant test

[0060]

[0061] It can be seen from the data in Table 3 that the deodorization evaluation results of the cat litter deodorants prepared in Comparative Examples 1-5 are average, mainly because less corresponding components are added during the preparation process, resulting in the prepared cat litter deodorants having a poorer deodorizing effect on odorous cat litters than those in Table 1.

[0062] Test Example 4

[0063] Select 5 enclosed spaces, each with a size of 2m 3 , a bucket of cat litter that has produced a foul odor is placed in each space, each bucket of cat litter weighs 8kg, the indoor temperature is controlled at 40-45°C, 5 spaces are selected as the deodorization test of the cat litter deodorant prepared in Comparative Examples 1-5, and the cat litter deodorant is directly sprayed on the cat litter; after the cat litter deodorant is sprayed, the ammonia, hydrogen sulfide concentration, methyl mercaptan concentration, and methyl sulfide concentration in the room are detected every 5 days, and the removal rates of ammonia concentration, hydrogen sulfide concentration, and odor concentration are calculated respectively with the blank room as the control, and the monitoring time is 30 days. The specific results are shown in Table 4 below. The detection methods used include GB / T14678-1993 Air Quality-Determination of Hydrogen Sulfide, Methyl Mercaptan, and Methyl Sulfide-Gas Chromatography, GB / T14675-1999 Air Quality-Determination of Malodor-Three-Point Comparison Stink Bag Method.

[0064] Table 4 Results of simulated cat litter deodorant test

[0065]

[0066] From the data in Table 4, it can be seen that the deodorizing effects of the cat litter deodorants prepared in Comparative Examples 1-5, such as removing toxic and harmful gases such as ammonia and hydrogen sulfide, are not ideal. This is mainly due to the fact that less corresponding components were added during the preparation process, so the overall deodorizing effects are quite different from those in Table 2.
