Description

Technical Field

[0001] This invention belongs to the field of disinfection and deodorization, specifically an inorganic plastic oxygen composite material and its application in a disinfection and deodorization system for pet environments. Background Technology

[0002] With the increasing popularity of pet ownership, the demand for disinfection and deodorization in pet homes, veterinary hospitals, and boarding facilities is becoming increasingly urgent, and people are placing higher demands on the safety, effectiveness, and durability of products. Currently, pet environment disinfection and deodorization products on the market are mainly divided into three categories, all of which have significant shortcomings: Chemical products mostly rely on fragrances to mask odors or strong oxidants to kill bacteria. Not only do they fail to eliminate odors at the source, but they may also irritate pets' sensitive respiratory tracts and skin. Long-term use can easily lead to dry fur, skin inflammation, and even residual harmful substances that may endanger human health. Physical adsorption products, such as activated carbon packs, can only passively adsorb odor molecules. Once saturated, they need to be replaced frequently, resulting in limited deodorization effects and high operating costs, making it difficult to meet the needs of all-day protection. Traditional peroxide disinfection products, while possessing certain bactericidal capabilities, suffer from the core problem of poor stability. Effective oxygen is easily decomposed prematurely, leading to a rapid decline in disinfection and deodorization effects. At the same time, they lack targeted catalytic systems and stabilization mechanisms, failing to balance high efficiency and long-lasting effects.

[0003] Furthermore, some existing products blindly increase the concentration of active ingredients to enhance effectiveness, further aggravating irritation and corrosiveness; while low-concentration products suffer from incomplete sterilization and deodorization, making it difficult to balance safety and effectiveness. Meanwhile, the specific needs of pet environments require products to be noiseless and residue-free during use, and adaptable to varying humidity and temperature conditions—features that most existing products cannot meet. Therefore, developing a safe, non-irritating, highly effective disinfection and deodorization material that is stable in storage and easy to use has become a pressing technical challenge for the industry. Summary of the Invention

[0004] The purpose of this invention is to provide an inorganic plastic oxygen composite material and its application in a pet environment disinfection and deodorization system, so as to make up for the shortcomings of the prior art.

[0005] The technical solution adopted in this invention is as follows:

[0006] An inorganic plastic oxygen composite material is prepared by a composite process from the following components by mass fraction:

[0007] Inorganic internal peroxide bridge composite compound 30-70g / 100g: a composite system of main peroxide and hydrogen peroxide addition crystal powder;

[0008] Inorganic mediated catalytic material 1.5-3.0g / 100g: composed of Co 0.5 Zn 0.5The composition consists of O nanosheets, carbon nanodots, cerium chloride, curcumin, and ZnS quantum dots in a mass ratio of 5:2:1:1:1;

[0009] Material balance and stabilization system 15-22g / 100g: composed of magnesium silicate, sodium citrate, and polyethylene glycol with a molecular weight of 2000-4000 in a mass ratio of 2:1:1;

[0010] The composite process is as follows: mixing, adding to a twin-screw extruder, extrusion, pelletizing, and curing to obtain the finished product; specifically: the above components are mixed and added to a twin-screw extruder, the extrusion temperature is controlled at 45-55℃, the screw speed is 250-280r / min, after extrusion, it is cut into particles with a particle size of 1.5-2.5mm, and then cured at 5-8℃ for 18-22h to form the finished product.

[0011] As a further technical solution, the main peroxide is selected from calcium peroxide or magnesium peroxide, and the hydrogen peroxide addition crystal powder is a mixture of urea hydrogen peroxide complex and sodium percarbonate in a mass ratio of 1-3:1, and is subjected to low-temperature eutectic composite modification treatment.

[0012] As a further technical solution, the preparation method of the low-temperature eutectic composite modification includes the following steps:

[0013] Weigh the main peroxide and hydrogen peroxide adduct crystal powder at a mass ratio of 2:1, pulverize them separately to a particle size of 80-150μm, and place them in a low-temperature mixer;

[0014] Introduce nitrogen into the mixer, control the temperature at -5~0℃, stir at a speed of 500-600 r / min, and premix for 40-50 min;

[0015] Add 1.0%-1.5% of the mass of the main peroxide as a composite dispersant, and continue stirring at low temperature for 90-100 minutes to form a eutectic structure;

[0016] The temperature was raised to 25-28℃ and vacuum dried for 3 hours to obtain a low-temperature eutectic modified inorganic internal peroxide bridge composite compound.

[0017] As a further technical solution, the composite dispersant is composed of calcium stearate and silicon dioxide mixed in a mass ratio of 1:2.

[0018] As a further technical solution, the vacuum drying process uses a vacuum degree of 0.1 Pa and a temperature of 60°C.

[0019] As a further technical solution, the preparation method of the material equilibrium and stabilization system includes:

[0020] Polyethylene glycol was heated to 65°C to melt, and magnesium silicate and sodium citrate were added and stirred and dispersed for 30 minutes.

[0021] Spray drying yields a composite stabilizer with a surface coating of polyethylene glycol;

[0022] Add anhydrous sodium carbonate to adjust the pH buffer range of the composite stabilizer to 6.5-7.5.

[0023] As a further technical solution, the spray drying controls the inlet air temperature to 130-140℃ and the outlet air temperature to 70-75℃.

[0024] Inorganic plastic oxygen composite material is used in pet environment disinfection and deodorization systems. The inorganic plastic oxygen composite material is dissolved in warm water at 30-40℃ at a mass ratio of 1:80-100 to obtain a mixed solution, which is then sprayed onto the pet environment disinfection and deodorization system.

[0025] As a further technical solution, 0.2-0.3 wt% of essential oil is also added to the mixture.

[0026] As a further technical solution, the essential oil is lavender essential oil, and the terpenoids in the lavender essential oil form a "photosensitive-aromatic synergistic system" with the inorganic mediated catalytic material ZnS quantum dots, which is then sprayed through a spraying device.

[0027] Beneficial effects:

[0028] Because this invention employs low-temperature eutectic composite modification to prepare inorganic internal peroxide bridge composite compounds, and through low-temperature stirring under nitrogen protection and the assistance of a composite dispersant, the main peroxide and hydrogen peroxide adduct crystals form a stable eutectic structure, thus inhibiting the premature decomposition of available oxygen at the microscopic level. This extends the product's shelf life and usability, thereby solving the core problems of easy decomposition and short action cycle of traditional peroxide materials; and the Co in inorganic mediated catalytic materials... 0.5 Zn 0.5 The synergistic catalytic system formed by O nanosheets and carbon nanodots can accelerate the conversion of available oxygen into reactive oxygen species. Cerium chloride and ZnS quantum dots further optimize the catalytic reaction rate, while curcumin enhances the stability of the catalytic system, making the disinfection and deodorization reaction faster and more complete, effectively solving the problem of low efficiency of traditional products. The material balance and stabilization system isolates the external environment through the coating effect of polyethylene glycol, and the combination of magnesium silicate and sodium citrate with pH buffer adjustment avoids direct reaction between the active ingredients and the environment, protecting the structural integrity of the active components at the microscopic level and solving the problem of easy loss and inactivation of active ingredients.

[0029] The synergistic effect of various components and processes forms a highly efficient technical system: the low-temperature eutectic modified inorganic internal peroxide bridge composite compound provides a stable source of active oxygen for disinfection and deodorization; the inorganic mediated catalytic material maximizes the reaction efficiency of active oxygen; and the material balance and stabilization system ensures the effectiveness of the former two. Combined with low-temperature extrusion at 45-55℃, a screw speed of 250-280 r / min, and a low-temperature curing process of 5-8℃, this ensures uniform mixing of all components while avoiding the destruction of effective ingredients by high temperatures, allowing for precise and continuous release of active oxygen during use. This synergistic effect not only improves the disinfection and deodorization effect but also ensures the stability of the product during storage and use.

[0030] This invention completely overcomes the shortcomings of traditional pet disinfection and deodorization products: the product contains no irritating chemical additives, and its gentle formula with lavender essential oil leaves no residue and causes no irritation, harming neither pets nor humans, thus meeting the safety requirements of pet-friendly environments. During disinfection, it achieves a kill rate of over 99.9% against Escherichia coli and Staphylococcus aureus, and a removal rate of over 94% for odorous gases such as ammonia and hydrogen sulfide, with an effective oxygen retention rate of over 95%, achieving a balance between high-efficiency disinfection, long-lasting deodorization, and stable storage. Furthermore, the product's preparation process is simple; it only requires dissolving in warm water according to a specific ratio before spraying, making it suitable for various scenarios such as pet homes and veterinary clinics, and easy to use. In summary, this invention, through the design and synergistic cooperation of its components and processes, successfully solves the technical problems of poor safety, limited effectiveness, and insufficient stability in existing products, providing a comprehensive and high-performance pet environment treatment solution with significant practical value and market potential.

Other raw materials, dosages and process parameters are the same as in Example 1.
