Abstract

The invention discloses a smokeless mosquito coil. The mosquito coil is prepared by charcoal dust, ash, starch and plant extract, wherein the plant extract is obtained by using folium artemisiae argyi and hemerocallis miner as raw materials and adding water for boiling and extracting; the ash is smashed fine powder after calcining mixtures of wood slag, coal slag, sandy soil and gravels; the preparation method of the mosquito coil is as follows: the charcoal dust and the ash are mixed to form a dry material; the pasted starch is added to form a wet material; the wet material is extruded to slices; the slices are punched to spiral blanks, and are dried to obtain dry blanks; the plant extract is attached on the dry blanks to obtain the smokeless mosquito coil. The smokeless mosquito coil adopts the natural plant extract as mosquito repellent, has good mosquito repelling effect, and has no toxic and side effects on human bodies. The smokeless mosquito coil further has such advantages as stable combustion, no smoke and dust and faint scent.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and in particular relates to a smokeless mosquito-repellent incense. Background technique [0002] Disc-type mosquito-repellent incense is mainly composed of mosquito-repellent incense and mosquito repellent. The components of mosquito repellent include organophosphorus (trichlorfon, chlorpyrifos, and pest-resistant, etc.), carbamates (propoxur, propoxur) and pyrethroids. Class (cypermethrin, proparthrin, allethrin, ES biothrin) three categories. Organophosphates and carbamates are highly toxic. Long-term use will cause physical discomfort, such as coughing and upper respiratory tract infections. They will also cause environmental pollution during industrial production, and their production and use are now prohibited. Pyrethroid mosquito repellents need to use kerosene and alcohol as solvents in the production process of mosquito coils and adopt a coating process, which means that mosquito ...
