Internal burning type electrically heated insect repellent piece

Abstract

An internal combustion type electrically heated insect repellent in the form of tablet is prepared from allethrin, tetramethrin, propargylthrin, piperonyl butoxide, diesel oil, starch, fatty acid, oxidant, talc powder and modified starch through proportional mixing and die pressing.

Description

Technical field: [0001] The invention relates to an internal-combustion electric heating insect repellent sheet, which belongs to the electric heating mosquito-repellent incense sheet. Background technique: [0002] The traditional electric heating mosquito-repellent incense sheet is made by soaking base paper or cotton fiber in the liquid medicine or drying it after dripping with the liquid medicine; it is conceivable that the active ingredient molecules (drugs) at this time are directly exposed and surrounded by the carrier ( Around the original paper sheet or cotton fiber) molecules, the more volatile drug molecules can easily escape within a few hours of use, but because the only driving force for the traditional electric heating mosquito-repellent incense sheet to push the drug molecules to escape is the temperature of the electric heater, therefore, After 4-5 hours, the volatilization temperature of the drug molecules remaining in the mosquito coil is higher than the t...
