Description

Technical Field

[0001] The invention belongs to the technical field of cat litter, and particularly relates to a deodorizing cat litter with antibacterial and insect repellent effects and a preparation method thereof. Background Art

[0002] Cat litter is an object provided by owners for their cats to bury feces and urine. It has good water absorption and is generally used together with a cat litter box (or cat toilet). Pour an appropriate amount of cat litter into the litter box, and when the cat needs to defecate, it will walk into the litter box and defecate on it.

[0003] Cat litter is a relatively traditional niche product. There are many types of cat litter commonly used, such as bentonite litter, crystal (silica gel) cat litter, paper litter, sawdust litter, etc. Among them, bentonite litter has the characteristics of low cost and water absorption and agglomeration, making it the current mainstream product. However, it has the disadvantages of poor water absorption, high specific gravity, troublesome cleaning after water absorption and agglomeration, and poor deodorization effect, which brings a lot of troubles to pet owners. Crystal cat litter has the disadvantages of poor water absorption, poor deodorization effect, and high specific gravity. Although paper litter and sawdust litter are more environmentally friendly and have good water absorption effects, they have the disadvantages of high cost and poor deodorization effect. Therefore, most of the cat litters on the current market cannot really solve the pain points of pet owners.

[0004] Many researchers are also constantly improving the preparation process of cat litter. A cat litter produced with attapulgite and bentonite as the main materials has poor water absorption and deodorization effects, and is difficult to clean up after absorbing water, which is similar to the products on the market. For details, please refer to CN106550894A~A cat litter with deodorization and insect repellency, CN108739427A~A bentonite cat litter and its preparation method, CN108849559A~A attapulgite natural mineral cat litter, CN105359991A~An environmentally friendly attapulgite mineral cat litter, CN101810146B~A production method of bentonite cat litter, CN107897009A~A bentonite cat litter and its preparation method, CN1279808C~Cat litter for pets and its preparation method. Using attapulgite and bentonite in a high proportion can effectively reduce production costs, but the poor deodorization effect of the material and the difficulty in cleaning up after moisture absorption are more prominent. It cannot be an ideal cat litter product for pet owners. In particular, the poor deodorizing effect easily attracts mosquitoes and breeds bacteria, which affects the health of pets and pet owners.

[0005] Therefore, developing a deodorizing cat litter with antibacterial and anti-insect effects is an ideal product urgently needed by cat owners. Summary of the invention

[0006] The purpose of the present invention is to provide a deodorizing cat litter with antibacterial and insect repellent effects and a preparation method thereof.

[0009] Furthermore, the plant fiber powder is one of hydroxymethyl cellulose, hydroxyethyl methyl cellulose, modified starch, bentonite, dextrin, and pectin, or a mixture of at least two of them. The preparation method of the modified starch is as follows: according to the mass fraction, 40 to 45 parts of starch are weighed, added to 60 to 65 parts of alkaline sodium sulfate solution with a concentration of 0.5-2.0 mol / L, 1 to 1.2 parts of epichlorohydrin are added, stirred at 45 to 50° C. for 4 to 5 hours, and then filtered, washed, and dried to obtain the modified starch.

[0039] The deodorization effect refers to the "QB / T 2761-2006 Method for Determination of Purification Effect of Indoor Air Purification Products" standard to test ammonia removal performance.

[0040] The indoor efficacy test method and evaluation experiment of mosquito repellent effect are carried out in accordance with the method of national standard GB / T13917.9-2009. The experiment uses Aedes albopictus, female adults that have not sucked blood for 3 to 5 days after emergence. The temperature is 26+1℃; the relative humidity is 65%+10%. Specific process: 300 mosquitoes are placed in a 300mm*400mm*400mm mosquito cage, and 4 testers are selected (half male and half female, and no alcohol, tea or coffee should be consumed before and during the test, and no products containing flavors should be used). Draw a 50mm×50mm skin area on the back of each hand, and evenly apply the mosquito repellent to be tested at a dose of 1.5μL / cm2 on one hand, exposing 40mm×40mm of skin, and tightly covering the rest. The other hand is a blank control. Apply the mosquito repellent for 2 hours, put your hand into the mosquito cage for 2 minutes, and observe whether there are mosquitoes coming to land and suck blood. Then test it every 0.5 hours. If only one mosquito comes to suck blood, the mosquito repellent is considered ineffective.
