[0003] Mosquito-repellent incense is a necessity in life. Mosquito-repellent incense has been an industry in my country since the Song Dynasty. The traditional concept has always been that the smoke of mosquito-repellent incense has the effect of repelling mosquitoes. Insect components, but the smoke itself is harmful to human health, especially the smoke produced by the burning of wood fibers in mosquito coils contains strong carcinogens

Abstract

The invention discloses a method for producing a smokeless mosquito coil by taking cumin straw as a main raw material. The method comprises the following steps: firstly drying, dewatering and crushing the cumin straw, then proportionally mixing with an adsorbent, carbon powder, an adhesive and a pesticide, adding water, uniformly stirring, moulding, pressing a layer of graphene onto each of the two surfaces of a sheet-like substrate, drying and dewatering to obtain the smokeless mosquito coil. By taking the cumin straw powder as the main raw material, the obtained mosquito coil has special aroma, and can expel wind and cold, warm kidney, relieve the gastric disorder and regulate Qi; in order to prevent smoke generation in the electric heating process, the adsorbent is added into a formula provided by the invention, and the adsorbent can adsorb toxic gases and large particulate substances; moreover, through addition of graphene, smoke can be confined inside, and only a nano-sized effective substance of which the particle size is smaller than the pore size of the graphene can be released into air. The smokeless mosquito coil is not only low in cost, good in effect and harmless to a human body, but also uses a large amount of cumin straws, so that farmers are effectively prevented from burning the straw to cause environment pollution.

Description

technical field [0001] The invention relates to the technical field of smokeless mosquito-repellent incense, in particular to a preparation method of smokeless mosquito-repellent incense with fennel straw as the main raw material. Background technique [0002] Fennel, the name of traditional Chinese medicine. It is the dry ripe fruit of umbelliferous plant fennel Foeniculum vuLgare Mill. Harvest the plants when the fruits are first ripe in autumn, dry them in the sun, lay down the fruits, and remove impurities. As a spice plant, cumin has a planting area of ​​about 300,000 mu nationwide. After the cumin seeds are picked and utilized, the cumin stalks are discarded or incinerated. Cumin straw contains anethole, anisone, anisaldehyde and other compounds. Anisaldehyde has the aroma of anise and hawthorn, which is strong and long-lasting. Anethole is used as fennel essence and licorice essence; it is also used in food, beverage, soap spices, etc. As a medicine, anethole has ...
