Embodiment 1

[0043] Step 1: Take 100 parts of water and heat it to 60°C, then add 20 parts of β-cyclodextrin, adjust the pH value of the water body to 10 with 30% sodium hydroxide, and stir with a stirrer for 10 minutes. Then add 20 parts of cationic etherifying agent 3-chloro-2-hydroxypropyl-trimethylammonium chloride, stir for 4 minutes with a stirrer at 800 r / min, and shake for 10 minutes with a 300 kHz ultrasonic cleaner. Then use a microwave frequency of 2450MHz to heat for 6 minutes, and then add hydrochloric acid after standing for 8 minutes to adjust the pH to 6.9. The solution was vacuum-dried at 70°C for 10 h, and the resulting dried product was dissolved in 20 parts of N,N-dimethylformamide. 200 parts of acetone were added to the solution, and the obtained precipitate was vacuum-dried at 50° C. for 15 hours to obtain modified β-cyclodextrin.

Embodiment 2

[0047] Step 1: Take 100 parts of water and heat it to 40°C, then add 5 parts of β-cyclodextrin, adjust the pH value of the water body to 8 with 30% sodium hydroxide, and stir with a stirrer for 5 minutes. Then add 4 parts of cationic etherification agent 2,3-epoxypropyltrimethylammonium chloride, stir for 2 minutes with a stirrer at a speed of 300 r / min, and shake for 5 minutes with a 300 kHz ultrasonic cleaner. Then use a microwave frequency of 2450MHz to heat for 2 minutes, and then add hydrochloric acid after standing for 5 minutes to adjust the pH to 6.5. The solution was vacuum-dried at 60°C for 8 hours, and the resulting dried product was dissolved in 10 parts of N,N-dimethylformamide. Add 100 parts of acetone to the solution, and then vacuum-dry the obtained precipitate at 40°C for 10 hours to obtain modified β-cyclodextrin.

[0051] Step 1: Take 100 parts of water and heat it to 80°C, then add 30 parts of β-cyclodextrin, adjust the pH value of the water body to 11 with potassium hydroxide with a mass fraction of 30%, and stir with a stirrer for 15 minutes. Then add 25 parts of cationic etherifying agent 3-chloro-2-hydroxypropyl-trimethylammonium chloride, stir for 5 minutes with a stirrer at a speed of 1000 r / min, and shake for 15 minutes with a 300 kHz ultrasonic cleaner. Then use a microwave frequency of 2450MHz to heat for 10 minutes, and then add hydrochloric acid after standing for 10 minutes to adjust the pH to 7.0. The solution was vacuum-dried at 80°C for 15 hours, and the resulting dried product was dissolved in 25 parts of N,N-dimethylformamide. Add 300 parts of acetone to the solution, and then vacuum-dry the obtained precipitate at 60° C. for 20 hours to obtain modified β-cyclodextrin.

Abstract

The invention relates to an environment-friendly deodorant and a preparation method thereof. The method comprises the following steps: firstly adding beta-cyclodextrin into a water body, then adjusting the pH value of the water body by using alkali liquor, and then adding a cationic etherifying agent and stirring, and adding hydrochloric acid to adjust pH, and then performing vacuum drying; dissolving the dried product with N, N-dimethylformamide, filtering, precipitating the filtrate with acetone, and carrying out vacuum drying on the obtained precipitate to obtain a modified beta-cyclodextrin; subjecting plant fibers to defibering to prepare a fiber suspension, and circularly grinding the fiber suspension in a colloid grinder; homogenizing by using a high-pressure homogenizer to obtain nano microfibrils; adding the nano microfibrils into water, then adding the modified beta-cyclodextrin and water-soluble chitosan, stirring, and finally carrying out ultrasonic treatment by using an ultrasonic cleaner to obtain the environment-friendly deodorant. The raw materials used by the environment-friendly deodorant are natural high polymer materials. The raw materials have the characteristics of simplicity, easiness in obtaining, reproducibility and the like, also have the characteristic of biodegradability, and are environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of deodorant preparation, and in particular relates to an environment-friendly deodorant and a preparation method thereof. Background technique [0002] Odor gas is a problem that is widely concerned at present, and people are making great efforts to control the emission of odor, trying to reduce the impact of odor on the environment and human body. Industrial production, garbage disposal, municipal sewage, etc. will produce malodorous gas, especially in industrial production, where the odor is relatively strong, such as paper mills, dye factories, rubber factories, pharmaceutical factories, pesticide factories, plastic factories, paint factories, etc. At present, it is more difficult to control the exhaust gas that can be perceived by the human body. Because of the complex types of malodorous gases, there are volatile organic compounds (VOCs), hydrogen sulfide (H 2 S) and ammonia (NH 3 ), etc., and the e...
