Embodiment 1

[0030] A safe and environment-friendly mosquito repellent, which is composed of the following components by mass fraction: icaridin 4.5%, chitosan 10%, sodium lignosulfonate 6%, pH buffer salicylic acid 1%, rutin 0.7% , citronellol 0.8%, urea peroxide 1.5%, ethanol 13% and water 62.5%.

[0031] The preparation method of the safe and environment-friendly mosquito repellent comprises the following steps:

[0032] S1: After fully mixing water and ethanol, add chitosan and sodium lignosulfonate, heat to 70°C, and stir evenly to obtain a mixed solution A;

[0033] S2: Cool the mixed solution A obtained in step S1 to 43° C., add icaridin, rutin, and citronellol, and stir evenly to obtain solution B;

[0034] S3: Lower the solution B obtained in step S2 to 30°C, add urea peroxide, stir evenly, and then use the pH buffer agent salicylic acid to adjust the pH to 7.5.

Embodiment 2

[0036] A safe and environment-friendly mosquito repellent, which is composed of the following components by mass fraction: 5% icaridin, 8% chitosan, 7% sodium lignosulfonate, 0.5% pH buffer salicylic acid, and 1% rutin , citronellol 0.5%, urea peroxide 2%, ethanol 11% and water 65%.

[0037] The preparation method of the safe and environment-friendly mosquito repellent liquid is similar to that of Example 1.

Embodiment 3

[0039] A safe and environment-friendly mosquito repellent, which is composed of the following components by mass fraction: icaridin 4%, chitosan 12%, sodium lignosulfonate 5%, pH buffer agent sodium salicylate 1.5%, rutin 0.5% %, citronellol 1%, urea peroxide 1%, ethanol 15% and water 60%.

[0040] The preparation method of the safe and environment-friendly mosquito repellent liquid is similar to that of Example 1.

Abstract

The invention belongs to the technical field of daily chemical preparations, and particularly relates to safe environment-friendly mosquito repellent liquid and a preparation method thereof. The mosquito repellent liquid is mainly prepared from the following components in percentage by mass: 4-5% of icaridin, 8-12% of chitosan, 5-7% of sodium lignin sulfonate, 0.5-1.5% of a pH buffering agent, 0.5-1% of rutin, 0.5-1% of citronellol, 1-2% of urea peroxide, 11-15% of ethyl alcohol and 50-75% of water. The mosquito repellent liquid disclosed by the invention is prepared by adding other auxiliary components on the basis of an active substance for eradicating mosquitoes, namely the icaridin, so that the mosquito eradicating effect of the icaridin is better. The mosquito repellent liquid disclosed by the invention has the advantages that the range of eradicating mosquitoes is wide, the time of maintaining the mosquito eradicating effect is prolonged, and the mosquito repellent liquid disclosed by the invention can replace traditional high-concentration mosquito repellent liquid.

Description

technical field [0001] The invention belongs to the technical field of daily chemical preparations, and in particular relates to a safe and environment-friendly mosquito repellent liquid and a preparation method thereof. Background technique [0002] Mosquitoes can transmit a variety of viruses, leading to human diseases, such as encephalitis, hemorrhagic fever, hepatitis, fever, mild discomfort, arthritis, etc. In China, mosquitoes mainly transmit dengue fever, meningitis B, malaria and type B diseases such as hepatitis. Taking hepatitis B as an example, the positive detection rate of hepatitis B surface antigen in the mosquitoes in the living room of hepatitis B patients is more than 85%, while the infection rate of mosquitoes in the living room of healthy people is less than 10%. When mosquitoes bite the blood of hepatitis B patients, they also inhale If infected with hepatitis B virus, and then bite healthy people, the hepatitis B virus will be transmitted to healthy pe...
