preparation example 1

[0026] Preparation Example 1: Preparation of Rose Flower Essential Oil

[0027] Use 4 mass times of 95% ethanol as the extraction solvent for dried rose flowers, and perform Soxhlet extraction under reflux for 2-4 hours, then filter with Buchner funnel and concentrate the filtrate to the original 1 / 30 of the volume, get rose flower essential oil.

preparation example 2

[0028] Preparation Example 2: Preparation of active ingredients from camphor leaves

[0029] Dried camphor leaves were soaked in 95% ethanol with 3 times the mass percentage for 3-5 hours, then microwave extraction, microwave power 900W, extraction time 60 minutes, and then the extract was concentrated to 1 / volume 20. Get the active ingredients of camphor leaves.

[0030] Unless otherwise specified, all parts in the following examples are parts by mass.

Embodiment 1

[0032] (1). Add 0.4 parts of pyrethroid and 2 parts of fluorescein isothiocyanate to 10 parts of ethanol and stir until the mixture is uniform;

[0033] (2). Continue to add 4 parts of rose flower essential oil and 3 parts of active ingredients of camphor leaves, then heat up to 40°C, continue to stir until the mixture is uniform, and obtain a mixed liquid;

[0034] (3). Make 80 parts of agar in a wet state into a slurry form, then add the mixed liquid obtained in step (2), stir uniformly, and then cool and shape to obtain the solid mosquito repellent of the present invention.

Description

Technical field [0001] The invention relates to a solid mosquito repellent and a preparation method of the solid mosquito repellent, belonging to the field of daily chemicals for mosquito repellent. Background technique [0002] In terms of physical form, current mosquito repellents are mainly divided into two types: solid or liquid. The solid is generally in the form of a sheet, which contains a mosquito repellent. The mosquito repellent is dispersed or volatilized into the air by heating to achieve the mosquito repellent effect. The liquid mosquito repellent is to dissolve the mosquito repellent ingredients in the volatile liquid, and realize the volatilization and emission of the volatile liquid through electric heating, so as to disperse the mosquito repellent ingredients into the indoor air together to achieve the mosquito repellent effect and effect. [0003] However, both solid and liquid mosquito repellents have certain defects. For solid mosquito repellent, its effectiv...
