Abstract

The invention discloses a camphor tree leaf mosquito repellent air fresher which comprises a camphor tree leaf extracting solution, lemon essential oil, menthol, citronella essential oil and the like. A preparation method of the camphor tree leaf mosquito repellent air fresher includes: A, camphor tree leaves, ethanol and distilled water are mixed according to weight ratio of 1:1:3-6 and put in a distillation still; B, the distillation still is heated to 50-100 DEG C, pressure of steam in the distillation still is maintained at 0.01-0.05 MPa, condensate is collected, and a camphor tree leaf extracting solution crude product is obtained; C, reduced pressure distillation is performed on the camphor tree leaf extracting solution crude product to obtain comprises camphor tree leaf extract concentrate; and D, by weight, 5-20 parts of lemon essential oil, 5-10 parts of menthol and 5-10 parts of citronella essential oil are dissolved in 5-30 parts of absolute ethanol, the camphor tree leaf extract concentrate obtained in the step C and distilled water are added and mixed evenly to obtain the camphor tree leaf mosquito repellent air fresher. The camphor tree leaf mosquito repellent air fresher is low in cost, excellent in mosquito repellent effect, fresh in smell and environment-friendly.

Description

technical field [0001] The invention relates to a camphor leaf mosquito repelling air freshener prepared by using natural camphor leaf extract concentrate, belonging to the technical field of comprehensive utilization of agricultural and forestry products; the invention also relates to a preparation method and application of the camphor leaf mosquito repellent air freshener. Background technique [0002] In order to avoid mosquitoes, mosquito-repellent incense produced from pyrethrum resin is widely used, but relevant tests have proved that it can cause obvious damage to the nervous system and hematopoietic system of the human body, so extra care should be taken when using it. [0003] At present, it has been found that many plant essential oils have certain mosquito repelling effects. E.g: [0004] Chinese patent 200910154435.0 discloses the application of a kind of Torreya essential oil in mosquito repellent. [0005] Chinese patent 200610042582.5 discloses a plant essen...
