Description

Technical Field

[0001] The invention relates to the field of deodorization, in particular to a composite deodorizing agent and a preparation method thereof. Background Art

[0002] Among all kinds of waste gas, malodorous gas is particularly polluting to the environment, bringing great impact and harm to the environment and residents' production. The odor can be perceived by people because of its high volatility and hydrophilicity and lipophilicity. The main reason for the odor of malodorous substances is that they contain characteristic odorous groups. Gas molecules containing odorous groups interact with olfactory cells and transmit information to brain nerves through olfactory nerves, thereby completing the identification of odors.

[0003] At present, the odor in garbage dumps, public toilets, slaughterhouses and other places is mainly solved by spraying deodorants. The types of deodorants are mainly plant and microbial, suitable for different environments, such as the plant deodorant and its preparation method disclosed in CN112316693A. The plant deodorant, by weight, includes: 2-4 parts of mint, 2-3 parts of ginger, 7-9 parts of dandelion, 6-7 parts of tea, 5-9 parts of grapefruit peel, 2-4 parts of Cistanche deserticola, 4-6 parts of Sophora japonica leaves, 5-7 parts of drug-absorbing grass, 2-4 parts of wormwood, 42-49 parts of aloe, 2-4 parts of mangosteen, 3-5 parts of orange, and 3-5 parts of eucalyptus leaves. The deodorant can remove ammonia, methane, and odor, and has good treatment effect and good durability; at the same time, it also has the effects of inhibiting, repelling insects, and purifying the air.

[0004] However, single plants or microorganisms always have their own limitations in removing various odors, and the composite agent obtained by simply combining plant and microbial formulas is difficult to exert the combined effects of both, and there are still shortcomings. Summary of the invention

[0005] The present invention aims to avoid the deficiencies of the prior art and provides a composite deodorizing agent and a corresponding preparation method.

[0006] The present invention solves the technical problem by adopting the following technical solution: a composite deodorizing agent, the composite deodorizing agent is composed of the following components:

[0007] Plant extract components, including tea extract, ginger extract, oak leaf extract, lavender extract, licorice extract, green persimmon extract, pine bamboo extract, and schizonepeta extract;

[0008] A microbial component, wherein the microbial component comprises a proteolytic enzyme, an aldehyde hunting factor and nano-diatomaceous earth;

[0009] The auxiliary component comprises a stabilizer, topologically structured titanium dioxide, syringol, a fermented rice product, a flavor improver, a chelating agent, an antioxidant, a plant preservative and a solvent.

[0020] Furthermore, the pine and bamboo extract is prepared by the following method: fresh pine bark and bamboo chips with a mass ratio of 1:1.2.5 are selected, the bark and bamboo chips are washed and then dried, the dried bark and bamboo chips are put into a furnace for burning at the same time, the burning flue gas is condensed through a condenser, the condensate is collected and then filtered to obtain the pine and bamboo extract.

[0021] The present invention has the following beneficial effects:

[0022] The present invention can promote the mutual mixing of other plant extract components through pine wood extract, and effectively integrate with microbial components and auxiliary components. The topological structure of titanium dioxide can effectively promote the mixing reaction and adsorb the sediment in the mixed solution to keep it clean.

[0023] The deodorant of the present invention adopts natural ingredients separated and extracted from natural plants and combined with microbial reactions, has antibacterial, bactericidal and deodorizing effects, is environmentally friendly and harmless, has no toxic side effects on the human body, is non-irritating, non-flammable and non-corrosive, can adsorb, cover and effectively decompose the odors of inorganic substances such as ammonia and hydrogen sulfide and organic substances such as low-molecular fatty acids, amines, aldehydes, ketones, ethers and halogenated hydrocarbons, can collide with odor molecules, react, and prompt the odor molecules to change their original molecular structures, make them lose the odor, and solve the odor problem from the source.

[0024] This deodorant is atomized into the air to form a large range of small mist particles, which can quickly and efficiently absorb odor molecules in the air. The adsorbed odor molecules can react with the deodorant containing bactericidal molecules and decompose into non-toxic and odorless substances. The decomposition products of odor molecules do not cause any harm to humans, animals, plants and soil, and there is no secondary pollution. It is safe and environmentally friendly.

[0025] This deodorant can quickly remove odors and formaldehyde generated during interior decoration. It can effectively decompose odors in pollutants through the special catalytic function of enzymes. It is non-toxic, harmless and has no side effects during the decomposition process. It can quickly wrap and decompose and remove malodorous gases such as ammonia NH3, hydrogen sulfide H2S, formaldehyde, methyl sulfide, methyl mercaptan, etc., and decompose and convert them into harmless substances such as water and carbon dioxide, thereby improving the living environment.

[0026] This deodorant has low cost and is easy to use. It can be widely used but not limited to: garbage transfer stations, farms, slaughterhouses, meat processing plants, printing and dyeing plants, pharmaceutical factories, leather factories, plastic factories, rubber factories, spraying workshops; industrial waste gas places such as organic waste gas, chemical waste gas spray towers, leather factory waste gas; public toilets, workshops, office buildings; civilian places such as pet deodorization, decoration odor, and new car odor.

[0027] The deodorant is diluted according to the actual scene requirements, with a maximum of 1:1000 times, but is not limited to the above dosage form. The above mixture can be made into various environmental deodorizing preparations according to known methods in the industrial field. Its usage and dosage are diluted according to the scene area and the size of the odor. If the smell is strong, it is generally used at 1:200 to 300 times, and if the smell is small, it can be used at 1:500 to 600 times. If the smell is mild, it can be used at 1:1000. The number of spraying times depends on actual needs. The raw materials of the present invention are selected from natural plant ingredients. The raw materials are mild and harmless to humans, livestock and poultry. It can remove environmental odors and odors through various channels. It also has the effects of sterilization, formaldehyde removal and mosquito repellent. It is relatively convenient in production process, easy to improve the environmental air, and remove the harm caused by odor pollution. It has good application prospects and market prospects.
