Problems solved by technology

The deodorization method of masking is to use some pleasant fragrances to cover up the odor, but when the fragrances volatilize, the odor molecules still exist and cannot be completely eliminated; the deodorization method of adsorption is to use some porous substances similar to activated carbon and diatomaceous earth to adsorb The disadvantage of this method is that the adsorption is selective (for example, the deodorization effect of activated carbon on ammonia, trimethylamine and other amines is extremely unsatisfactory)
Moreover, the active carbon needs to be replaced or regenerated regularly, and the cost is high; the feasibility of deodorizing by odor or enzyme reaction is not high

Embodiment 1

[0023] Embodiment 1: Preparation of EGCG-ZnO nanoparticles

[0024] According to the molar ratio of EGCG and ZnO as 1:50, accurately weigh 4.58g EGCG and 68.2g zinc chloride respectively, dissolve EGCG and zinc chloride in water, adjust the pH of the system to 7.0 with 1.25M sodium hydroxide solution , the mixed solution was refluxed at 100° C. for 3 h, allowed to stand at room temperature for 72 h, centrifuged at 15,000 rpm for 15 min, and the precipitate was collected. The precipitate was repeatedly washed with water and dried to obtain EGCG-ZnO nanoparticles.

Embodiment 2

[0025] Embodiment 2: Preparation of EGCG-ZnO nanoparticles

[0026] According to the molar ratio of EGCG and ZnO as 1:60, accurately weigh 4.58g EGCG and 81.8g zinc chloride respectively, dissolve EGCG and zinc chloride in water, adjust the pH of the system to 7.5 with 1.25M sodium hydroxide solution , the mixed solution was refluxed at 100° C. for 2 hours, allowed to stand at room temperature for 24 hours, centrifuged at 12000 rpm for 20 minutes, and the precipitate was collected. The precipitate was repeatedly washed with water and dried to obtain EGCG-ZnO nanoparticles.

Embodiment 3-7

[0027] The preparation of embodiment 3-7 liquid deodorant

[0028] The liquid deodorant of embodiment 3-7 comprises the component of mass percent shown in the table below:

[0029]

[0030]

[0031] Preparation steps: mix hydroxypropyltrimethylammonium chloride chitosan, zinc salt, aminocaproic acid and water, stir to dissolve, then add subtilisin sodium and cetearyl glucoside, stir evenly, Add nano TiO 2 , EGCG-ZnO nanoparticles, plant essential oil and γ-caprolactone, and use a high-speed homogenizer to homogenize for 3 minutes to obtain a liquid deodorant.

Abstract

The invention discloses a liquid deodorant and a preparation method thereof. The liquid deodorant is prepared from the following components in percentage by mass: 6%-9% of nano titanium dioxide, 5%-10% of EGCG-ZnO nano particles, 6%-10% of chitosan quaternary ammonium salt, 3%-6% of zinc salt, 1%-4% of plant essential oil, 3%-5% of gamma-caprolactone, 1%-3% of sodium surfactin, 3%-5% of cetostearyl glucoside, 2%-6% of auxiliaries and the balance water. The liquid deodorant disclosed by the invention integrates a plurality of deodorization technologies; the deodorant has the characteristics ofcomprehensive deodorization effect, high efficiency and quick-acting deodorization, can inhibit the generation of odor from the source, radically and thoroughly eliminate the odor, is harmless to human bodies, is suitable for antibacterial odor removal and odor treatment of home furnishing, hotels, hospitals, meeting places, other public places and facilities thereof, and has wide application range.

Description

technical field [0001] The invention relates to the field of deodorization, in particular to a liquid deodorant, in particular to a liquid deodorant and a preparation method thereof. Background technique [0002] Odor substances are highly volatile substances with various chemical properties, such as acidity, alkalinity, polarity and nonpolarity, and mainly exist in sewage treatment plants, garbage dumps, farms and other places. Odor pollution has a great impact on the surrounding ecological environment, and it will also cause serious harm to human health, causing people to experience symptoms such as olfactory disorders, nausea, headaches, cancer, and distortion. With the increasing requirements of environmental protection, the problem of odor pollution has been widely concerned and highly valued by people. The research on deodorization is of great significance and has broad application prospects. [0003] The composition of the odor is complex and difficult to control. A...
