Abstract

The invention provides a wood insect-proof essential oil. Raw materials comprise a plant compound extract and a solvent, wherein the plant compound extract is a mixture of a chinaberry leaf extract, achinaberry flower extract, a celastrus angulatus leaf extract and platycaryae extract, and an extract is a mixture of an ethyl acetate extract and an ethanol extract in a mass ratio of 1 to 2. The wood insect-proof essential oil does not contain chemical insecticidal ingredients and preservatives, and the ingredients are all plant materials, environmentally friendly, non-polluting, non-toxic andharmless. The essential oil is capable of purifying air and not damaging clothes, can prevent frogs and eliminate odor, is also suitable for infants and young children, and can be used not only for plant pest control, but also for pest control in daily life at home.

Description

technical field [0001] The invention belongs to the technical field of insect repellents, and in particular relates to a wood insect repellent essential oil and a preparation method thereof. Background technique [0002] Household insect repellents are generally placed in indoor wardrobes or lockers, and use the odor produced by the natural volatilization of insect repellents to prevent insects, moths and remove odors. [0003] In the prior art, there are many kinds of insect repellents, but the most commonly used in the living room is moth balls, which are divided into synthetic moth balls and natural moth balls. Synthetic moth balls are artificially synthesized aromatic organic compounds, which have obvious pungent odor and are toxic. Side effects, harmful to the human body. [0004] Therefore need to develop a kind of natural, environment-friendly, nontoxic and harmless novel insect repellant. Contents of the invention [0005] In order to solve the problems in the pr...
