Abstract

The invention provides a mosquito repellent tablet and a preparation method thereof, relating to the field of mosquito repellent products. The mosquito repellent tablet of the invention comprises thefollowing raw materials in parts by weight: 500-950 parts of a matrix, 50-450 parts of plant essential oil, 100-150 parts of sustained release agent, 10-50 parts of preservative, 20-100 parts of foaming agent, 5-50 parts of foaming accelerator part, 0.5-1.5 part of a bridging agent, 50-300 parts of filler and 5-50 parts of lubricant. The mosquito repellent tablet of the invention can control the volatilization amount of essential oil, improve the volatilization uniformity of essential oil in the early and late stages, prolong the mosquito repellent lasting period and improve the mosquito repellent effect.

Description

technical field [0001] The invention relates to the field of mosquito repellent products, in particular to a mosquito repellent sheet and a preparation method thereof. Background technique [0002] Mosquito repellent sheets are common mosquito repellent products, and the existing plant essential oil mosquito repellent sheets are mainly divided into surface type and mixed type. The surface-type mosquito repellent sheet is obtained by spraying or soaking plant essential oil on the surface of the substrate. Its disadvantage is that the content of mosquito repellent essential oil is small, and it is mainly concentrated on the surface of the mosquito repellent sheet. The interior of the substrate basically does not contain mosquito repellent essential oil components. Larger, the essential oil content drops rapidly, resulting in less essential oil content in the follow-up, and poor mosquito repellent effect. The hybrid mosquito repellent sheet is made by fully mixing the mosquito...
