Mould-proof environmentally-friendly smokeless mosquito coil and production process thereof

Abstract

The invention relates to the technical field of chemical industry, and in particular relates to a mould-proof environmentally-friendly smokeless mosquito coil and a production process thereof. The mosquito coil comprises the following the components in parts by weight: 50-60 parts of sticky powder, 20-30 parts of corn flour, 10-20 parts of starch, 20-35 parts of lignite, 20-30 parts of light calcium carbonate powder, 2-8 parts of potassium nitrate, 0.2-0.9 part of a toner, 2-5 parts of copper sulfate, and 70-80 parts of water. Compared with a traditional smokeless mosquito coil, the smokelessmosquito coil provided by the invention has a plurality of advantages that carbon powder is not added, and gases including CO which are unfavorable to human health are not generated during use; the smokeless mosquito coil provided by the invention is prepared by refining of pure natural materials, and does not pollute the environment; the copper sulfate is used as a mould inhibitor, and the coppersulfate is non-toxic and long-acting, has a low VOC content, thermal stability, and very good killing and inhibiting ability against fungi, bacteria, mould and enzymes; the lignite subjected to desulfurization and denitrification can greatly reduce the smoke discharging amount and reduce pollution to the environment; the potassium nitrate is used as a combustion improver, and can prevent the smokeless mosquito coil from being suffocated in the ignition process; and after a mosquito coil blank is subjected to compression molding and drying, secondary drying is performed, so that the smokelessmosquito coil can be effectively prevented from being cracked because heating is rapid in the drying process.

Description

Technical field [0001] The invention relates to the technical field of chemical engineering, in particular to an anti-mold and environmentally friendly smokeless incense and a manufacturing process thereof. Background technique [0002] Mosquito coil is a kind of mosquito repellent. The smoke emitted by the drug after it is ignited can drive away or kill mosquitoes. Our country has a very long history of mosquito-repellent incense, the traditional mosquito-repellent incense and coil incense. The smoke burned by mosquito coils contains 4 types of substances harmful to the human body, namely ultrafine particles-soot (particulate matter with a diameter of less than 2.5 microns), polycyclic aromatic hydrocarbons (PAHs), carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene. At the same time, in addition to these four types of obvious harmful substances, there are a large number of organic fillers, binders, dyes and other additives in the mosquito coils to make the m...
