Problems solved by technology

[0003] At present, there are many types of solid air fresheners available on the market, and most of them have complex components, which have poor dust suppression and sterilization effects, and are prone to odors that make indoor people feel uncomfortable.
And most of the solid air fresheners are liquid sprays, which cannot continuously and automatically purify and freshen the air, and need to be sprayed artificially to play the role of fresh air; while some commonly used indoor places or closed workplaces such as the car need continuous Purify and refresh the air, so provide a solid air freshener with good air purification effect

Embodiment 1

[0018] First add 100kg of agar powder into 100kg of deionized water for heating and stirring to obtain an agar dispersion;

[0019] Next, add 10 kg of fresh fragrance agent, 1 kg of aluminum oxide (50 nm), and 1 kg of ethylene glycol monobutyl ether into 50 kg of ethanol, and select a rotation speed of 2000 rpm to stir for 1.5 h to obtain a mixed solution;

[0020] Finally, when the agar dispersion is cooled to 30-35°C, the mixed solution is added to the agar dispersion for stirring, mixing, and natural cooling and solidification to obtain the solid air freshener, which is denoted as A1; It is prepared by the following method: first mash mint, tangerine peel, chrysanthemum, and aloe vera, then add the mashed mixture to ethanol and heat at 25°C for 1.0h, then stir and filter, and then add activated carbon to the The deodorant was obtained by filtering the obtained filtrate and closing the system for 5 hours to remove color.

Embodiment 2

[0022] First add 100kg of agar powder into 300kg of deionized water for heating and stirring to obtain an agar dispersion;

[0023] Next, 15kg of fresh fragrance agent, 3kg of aluminum oxide (80nm), and 2kg of ethylene glycol monobutyl ether were added to 100kg of ethanol, and the selected rotation speed was 2500rpm and stirred for 1.2h to obtain a mixed solution;

[0024] Finally, when the agar dispersion is cooled to 35°C, the mixed solution is added to the agar dispersion for stirring and mixing, and the solid air freshener is obtained after natural cooling and solidification, which is denoted as A2; Prepared by the method described above: first mash mint, tangerine peel, chrysanthemum, and aloe vera, then add the mashed mixture to ethanol and heat at 28°C for 0.8h, then stir, filter, and then add activated carbon to the filtered Put in the obtained filtrate and close the system to stand still for 8h to remove the color to obtain the fragrance clearing agent.

Embodiment 3

[0026] First add 100kg of agar powder into 500kg of deionized water for heating and stirring to obtain an agar dispersion;

[0027] Next, 20kg of fresh fragrance agent, 5kg of aluminum oxide (100nm), and 3kg of ethylene glycol monobutyl ether were added to 150kg of ethanol, and the selected rotating speed was 3000rpm and stirred for 1.0h to obtain a mixed solution;

[0028] Finally, when the agar dispersion is cooled to 35°C, the mixed solution is added to the agar dispersion for stirring and mixing, and natural cooling solidifies to obtain a solid air freshener, which is denoted as A3; Preparation method: first mash mint, tangerine peel, chrysanthemum, and aloe vera, then add the mashed mixture to ethanol and heat at 30°C for 1.0h, then stir and filter, and then add activated carbon to the filtered Put it in the filtrate and close the system for 10 hours to remove the color to obtain the fragrance clearing agent.

Abstract

The invention discloses a solid air freshener. The solid air freshener consists of agar powder, deionized water, ethanol, a freshener, active aluminum oxide and ethylene glycol monobutyl ether, wherein relative to 100 parts by weight of the agar powder, the content of the deionized water is 100-500 parts by weight, the content of the ethanol is 50-150 parts by weight, the content of the freshener is 10-20 parts by weight, the content of the active aluminum oxide is 1-5 parts by weight, and the content of the ethylene glycol monobutyl ether is 1-3 parts by weight. The solid air freshener can be used for persistently performing air purification and refreshing indoor or at a closed work place. A manufacturing process of the solid air freshener is simple and easy, raw materials are simple and easy to obtain, and quantitative production can be achieved.

Description

technical field [0001] The invention relates to a solid air freshener, in particular to a solid air freshener and a preparation method thereof. Background technique [0002] Indoor air quality is very important to human health, especially the frequent environmental pollution in recent years has made people pay more attention to air quality. Indoors, such as many public places, due to poor ventilation and high flow of people, the indoor air cannot be purified through its own air circulation; and the accumulation and floating of dust and the stagnation of various odors make people feel uncomfortable indoors, and are prone to Bacterial infection. Therefore, the control of indoor air quality is very important. Usually people will use simple and easy-to-operate liquid spray solid air fresheners with anti-virus effect and aromatic smell to kill germs in the air and improve peculiar smell. [0003] Currently, commercially available solid air fresheners come in a wide variety and...
