Problems solved by technology

In order to reduce the amount of smoke produced in mosquito-repellent incense, the content of carbonaceous powder in its combustible raw materials is usually high. Due to the lack of charcoal resources in our country and the forestry department's restrictive use rules for wood, combustible materials from other fields have also been used in recent years. Non-recycling materials (such as waste paper, sawdust, etc.) are used instead of carbonaceous powder and other raw materials as the burning base material of mosquito coils, but this type of material will generate a lot of smoke, making the ultrafine particles and smoke content in the air Increase, affect the air quality, bring great inconvenience, not conducive to the use of infants, pregnant women, the elderly or asthma patients, need to be further improved

Abstract

The invention relates to low-smoke sterilization disc type mosquito-repellent incense and a preparation method thereof, and the low-smoke sterilization disc type mosquito-repellent incense comprises the following raw materials: hemp stem core powder, wormwood powder, an adhesive, zeolite powder, bentonite, diatomite, carboxymethyl cellulose and an insecticide. The hemp stem core powder and the wormwood powder are used as combustible substances to replace carbon powder and wood powder in traditional raw materials, the prepared coiled mosquito-repellent incense generates little smoke during combustion, hemp stem cores are recycled, the raw materials are saved, the hemp stem cores can be recycled, and environmental friendliness is improved.

Description

technical field [0001] The invention belongs to the field of mosquito coil preparation, in particular to a low-smoke sterilization disc type mosquito coil and a preparation method thereof. Background technique [0002] As a commonly used daily chemical product, mosquito coils are mainly used for mosquito repellent in daily life. The common disc type mosquito coils are dipped or sprayed with mosquito repellent liquid (usually pyrethroids) after the mosquito coil blank is formed. become a finished product. With the burning of the coiled mosquito coil, the mosquito repellent liquid adsorbed on the mosquito coil blank will slowly dissipate, which has the effect of killing and repelling mosquitoes. [0003] In the manufacture of traditional coil mosquito coil blanks, charcoal powder (charcoal powder or bamboo charcoal powder) and wood powder (cedar powder, elm powder, etc.) are used as combustible materials to add binders, combustion accelerants, and flame retardants. It is for...
