Abstract

The invention provides a wormwood mosquito-repellent incense, which is prepared from the following raw materials by weight: 20-25 parts of wormwood, 5-12 parts of biomass fiber, 3-5 parts of rosin, 3-7 parts of a marigold extract and 5-10 parts of deionized water. The mosquito-repellent incense is prepared from wormwood, biomass fibers and rosin and is matched with a small amount of mosquito-repellent liquid to achieve dual mosquito repelling, the marigold extract is obtained through ultrasonic-assisted extraction and supercritical fluid extraction, a large number of mosquito-repellent aromatic components are effectively extracted and compounded with wormwood, and a synergistic interaction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of mosquito repellent products, in particular to a mugwort mosquito coil and a preparation method thereof. Background technique [0002] Since the 20th century, the Japanese Shangshan Matsusan used the Archimedes spiral and the Chinese Yin-Yang gossip principle to make spiral-shaped mosquito-repellent incense. Its low price has occupied a leading position in my country's household hygiene insecticide market. At present, the traditional disc-type mosquito-repellent incense is all with carbonaceous powder (charcoal powder or bamboo charcoal powder), and wood powder (fir powder, wood powder etc.) is added binding material (elm bark powder, bakelite powder, α-starch, Methyl cellulose), antifungal agent, flame retardant, flame retardant, etc. are formed by spraying after homogenization, stirring and blending, extrusion, stamping and drying. Because the particle size of carbonaceous powder is very fine (about 100...
