Water-based electric heating liquid mosquito-repellent incense and preparation method thereof

Abstract

The invention discloses water-based electric heating liquid mosquito-repellent incense and a preparation method of the water-based electric heating liquid mosquito-repellent incense. The water base electric heating mosquito-repellent incense comprises the following components by weight percent: 0.1-1.8% of pyrethriod mosquito-repellent component, 45-80% of glycol ether solvent, 0-0.6% of anti-oxygenant, 0-0.5% of cosolvent and the balance of deionized water. The water-based electric heating liquid mosquito-repellent incense provided by the invention is environment-friendly, excellent in effect, safe and incombustible, and stable to volatilize, and further has the effect of reducing the volatile organic compounds (VOC) content (low VOC), meets the concept of 'low carbon', and is an ideal choice for healthy living environment.

Description

technical field [0001] The invention relates to an environment-friendly electric heating liquid mosquito coil, which belongs to the technical field of daily chemicals, in particular to a water-based electric heating liquid mosquito coil and a preparation method thereof. Background technique [0002] Since Japan developed the first electric heating liquid mosquito-repellent incense product in 1966, due to the breakthrough of many technical problems, and because the electric heating liquid mosquito-repellent incense is easy to use, stable and safe, this dosage form has become the fourth choice for global consumers to prevent and control mosquitoes. One of the larger dosage forms. my country's electric heating liquid mosquito coils appeared in the late 1980s, and its sales have recently increased by about 25% per year. However, their formula systems are all oil-based, that is, organic alkanes are used as solvents, and the carbon chain distribution is generally C13~C16, C14~C19...

AI Technical Summary

Problems solved by technology

[0004] 1. Alkane solvents are derived from industrial distillation and hydrofining of petroleum, but with the rise of petroleum prices in recent years, it has caused certain cost pressures on enterprises;

[0005] 2. The alkane solvent is formed by rectification, etc., and its carbon chain distribution is relatively wide, especially among the low-carbon alkane, which is easy to form organic volatiles, namely VOC. In the daily home life of consumers, it will be used by heating and using electric heating liquid mosquito coils. Natural volatilization causes pollution to the home environment and has a certain impact on the health of consumers;

[0006] 3. Alkane solvents can burn when exposed to open flames, and are flammable liquids, which bring certain fire risks to transportation, storage and household use

[0008] The existing technology for preparing water-based electric heating mosquito-repellent incense (patent publication number: CN102232379A) ​​is thermodynamically unstable due to the use of an emulsified formula system, and cannot be volatilized by the existing matching heating appliances, and the actual application value is difficult to evaluate
