Abstract

The invention provides antibacterial cat litter and a preparation method thereof, and relates to the technical field of cat litter preparation. According to the invention, a double-adding mode is adopted, the long-acting antibacterial hydrogel chemical antibacterial agent is added into cat litter raw materials, and after the cat litter raw materials are dried in a drying box at 150-200 ℃ for 10-15min, the plant extract composite liquid antibacterial agent is uniformly and thinly coated on the surfaces of cat litter particles at 360 ℃ by adopting ultrasonic spraying, so that potential risks caused by direct contact of cat skin with the chemical antibacterial agent can be avoided, deactivation of the plant extract composite liquid antibacterial agent caused by high temperature is avoided, and the external spraying and internal adding antibacterial agent adding mode can enable microorganisms to contact the plant extract composite liquid antibacterial agent for the first time to influence propagation of the plant extract composite liquid antibacterial agent and ensure slow release of the chemical antibacterial agent to achieve a lasting antibacterial effect. And the cat litter can be quickly dried by using the cat litter residual temperature, so that the energy consumption is reduced.

Description

Antibacterial cat litter and preparation method thereof Technical Field The invention relates to the technical field of cat litter preparation, in particular to antibacterial cat litter and a preparation method thereof. Background Cat litter is an important hygiene product for feeding companion animals, and the deodorizing and antibacterial properties of cat litter directly affect the quality of the feeding environment, the health of pets and the user experience. Under the moist and organic-rich use environment, the cat litter is extremely easy to grow microorganisms such as bacteria and mould, so that malodorous substances such as ammonia and hydrogen sulfide are generated, and the cat litter can become a potential medium for pathogen transmission, thereby threatening the health of pets and family members. Therefore, an effective antibacterial technology has become one of the core research directions for improving the functionality and safety of cat litter products. At present, the bacteriostasis technology adopted by cat litter in the market mainly depends on a single bacteriostasis mechanism, and can be roughly divided into two types according to the action mode and material source: The chemical bacteriostat adding technology is that silver ion, quaternary ammonium salt, p-chloro-m-xylenol (PCMX) and other broad-spectrum chemical bacteriostat are mixed into the raw material before the cat litter is formed or are attached to the particle surfaces through post treatment. The technology has the characteristics of strong antibacterial effect and rapid action. However, a significant disadvantage is that the bacteriostatic agent may come into direct and sustained contact with the cat's paw pad, skin, and even the respiratory tract (by dusting). The frequent licking of the cat with the hair also increases the risk of oral ingestion, and long-term exposure may cause skin irritation and anaphylaxis, even cause potential burden on liver and kidney functions, and have serious health and safety hazards for pets. The plant source bacteriostat adding technology is that in order to meet the safety challenge of chemical preparations, partial products are turned to natural components extracted from peppermint, camphor, tea tree, mugwort and other plants to be used as bacteriostat. Such technologies are mainly based on the concept of "natural" and "safe" and are more attractive to consumers. Their use faces serious process and performance bottlenecks, most plant extracts are sensitive to heat, and high temperature drying (typically above 150 ℃) is commonly involved in cat litter production to achieve rapid cure and dehumidification. In the high-temperature link, the plant active ingredients are extremely easy to decompose, volatilize or oxidize and deactivate, but are easy to deactivate due to high Wen Jiagong, and the antibacterial effect is greatly attenuated or even completely lost due to poor antibacterial durability. Therefore, even if the antibacterial agent is added into raw materials, the effective antibacterial concentration in the final finished product is difficult to ensure, and the defects of poor antibacterial durability and unstable effect are exhibited. In summary, the prior art falls into the two difficulties that the chemical bacteriostat has lasting efficacy but outstanding safety risk, and the plant bacteriostat has high safety but is difficult to survive in a key production process, so that the long-acting bacteriostasis capability is insufficient. The limitation of the single bacteriostasis mode makes the market need an innovative solution which can give consideration to instant efficient bacteriostasis, long-acting safe maintenance and is compatible with the existing production process. Disclosure of Invention The invention provides antibacterial cat litter and a preparation method thereof, in order to ensure that the conventional cat litter has high-efficiency antibacterial performance, long-acting antibacterial maintenance and is friendly to cat skin. In a first aspect, the application provides a preparation method of antibacterial cat litter, comprising the following preparation steps: Uniformly mixing a chemical antibacterial agent, starch and water to obtain a premix, uniformly mixing the premix and a main raw material of the cat litter, puffing and granulating to obtain a main cat litter, spraying a plant extraction antibacterial agent solution on the surface of the main cat litter, and drying to obtain antibacterial cat litter; The plant extract bacteriostatic agent solution comprises plant extracts and water, wherein the plant extracts are any one or a combination of more of sunflower extracts, pomegranate extracts and spearmint extracts. Further, the chemical antibacterial agent is any one or a combination of a plurality of guanidine, ammonium salts and phenol antibacterial agents. Further, the mass ratio of the chemical bacteriostat to the starch in the premix is 1:5-15. Further, the starc
