Embodiment 1

[0031] Embodiment 1: the invention provides a kind of solid air freshener and preparation method thereof, described solid air freshener is made up of the component of following parts, and described parts are parts by weight:

[0032]

[0033]

[0034] The preparation method of solid air freshener of the present invention is as follows:

[0035] (1) Preparation of peppermint essential oil: cut the picked mint leaves into 1cm 2 The fragments are placed in a distillation vessel, and then 200°C high-temperature steam is passed into it, and the essential oil containing aromatic components in the plant gradually diffuses into the water vapor to form an oil-water azeotrope; (2) After 3 hours, the azeotrope After cooling and standing for 1 hour, use a liquid separation device to separate, dry with anhydrous sodium sulfate and seal to obtain peppermint essential oil, and store in the dark at 0°C;

[0036] (3) Gradually add carrageenan and agar into deionized water, gradually rai...

Abstract

The invention relates to a solid air freshening agent and a preparation method thereof and belongs to the field of air purification. Natural peppermint essential oil used by the solid air freshening agent can remove harmful substances in the air, so that the solid air freshening agent has effects of air purification and bacteria resistance and inhibition. Meanwhile, due to a variety of health efficacies of the natural peppermint essential oil, people can feel comfortable and fresh after inhaling aroma. Adopting activated carbon, the solid air freshening agent has the effect of adsorbing suspended particles and harmful gases such as formaldehyde in the air and is great in adsorption capacity. Taking carrageenan and agar as a carrier, the solid air freshening agent is safe and non-toxic. The solid freshening agent is simple in manufacture, safe and low in consumption.

Description

technical field [0001] The invention relates to an air freshener, in particular to a solid air freshener and a preparation method thereof, belonging to the field of air purification. Background technique [0002] Indoor air quality is very important to human health. Especially the outbreak of SARS in 2003 has prompted people to pay more and more attention to the problem of microbial pollution in indoor air. In addition, many public places cannot be naturally purified by fresh air due to poor ventilation and other reasons. The environment will inevitably accumulate peculiar smells, which will make people feel uncomfortable. [0003] Air is the transmission medium of many diseases. Microorganisms in the air, especially pathogenic bacteria, are very harmful to human health. Therefore, air sterilization is an important measure to purify the air, prevent diseases, and control the spread of diseases. It has become a main choice for people to use a solid freshener with sterilizing...
