Problems solved by technology

[0005] (1) For the botanical pesticides of plant essential oils and some specific pyrethroid chemical pesticides, although the release rate of their effective substances can be slowed down by encapsulation with microcapsules, it has been proved by experiments that microcapsules The structure has a good coating effect on substances with medium molecular weight, but the coating effect on botanical pesticides such as eucalyptol, D-limonene, cinnamaldehyde, cinnamyl alcohol, citronellal, eugenol or nerol is poor. not ideal
[0006] (2) Directly use slow-release agents or solvents to adjust the volatilization rate of active substances, and the adjustment effect is difficult to control. At the same time, it is difficult to apply to a class of mosquito repellent effective substances
[0007] (3) The method of microcapsule coating needs to prepare the coating material of microcapsules first, and then perform coating. The preparation steps are complicated and difficult

Abstract

The invention discloses a mosquito-repellent volatile core and a preparation method thereof. The mosquito-repellent volatile core is prepared by mixing mosquito-repellent liquid medicine and a liquid slow-release carrier according to the weight ratio of 100:(10-200) into combined dropwise adding liquid, the combined dropwise adding liquid is dropwise added to a framework carrier, the mosquito-repellent volatile core is prepared, the liquid slow-release carrier is non-fluidics fluid, and through the space resistance of the non-fluidics fluid, small molecular compounds with high volatilization rate and solvents with good volatility in a suspension system can move in the fluid in a decelerated manner and slowly overflow from the non-fluidics fluid material, the purpose of slowing down the release speed of mosquito-repellent effective substances is achieved, and the mosquito-repellent volatile core is especially suitable for slow-release control of botanical pesticides with small molecular weight.

Description

technical field [0001] The invention relates to a mosquito repellent dispersant core and a preparation method thereof, in particular to a mosquito repellent dispersant core with adjustable volatilization rate and a preparation method thereof, belonging to the field of household hygienic insecticide products. Background technique [0002] At present, there are a variety of mosquito repellent products on the market. The common ones are mosquito repellent liquid, mosquito repellent toilet water, mosquito repellent sheet, mosquito repellent patch, mosquito repellent ring, etc. The active ingredients of these mosquito repellent products are roughly divided into two categories, one is containing Mosquito repellent active ingredients such as mosquito repellent, DEET or pyrethroids, and other natural and environmentally friendly mosquito repellent products containing natural plant essential oils such as citronella oil and eucalyptus essential oil. The current situation is: the activ...
