Problems solved by technology

The current method of using mosquito-repellent incense is to ignite or electric heating takes about 8 hours, because the powder in the mosquito-repellent incense is more, the user has to spend a long time in an environment full of smoke, poisoning is inevitable, it will pollute the environment, and it will also increase Great fire hazard
In order to change this situation, people have researched and invented smokeless mosquito-repellent incense. Although the emission of smoke has been reduced, the defect is that the mosquito-repellent effect of mosquito-repellent incense has been affected, and even the promotion and use of the product have been affected.

Embodiment 1

[0016] The base materials and additives in this embodiment include by weight: 65 parts of charcoal powder, 5 parts of sodium carboxymethyl cellulose, 5 parts of wood powder, and 0.5 part of dextro-trans allethrin. method to obtain mosquito coils. 15 grams of the incense is ignited and used in a room of 100 square meters, and the volatilization rate of its active ingredients is determined to be 75%, and the fumigation time is 2.5 hours, which can completely prevent mosquitoes.

Embodiment 2

[0018] The base materials and additives in this embodiment include by weight: 75 parts of charcoal powder, 15 parts of sodium alginate, 10 parts of wood powder, and 2 parts of dextro-trans allethrin. Preparation of mosquito coils. 12 grams of the incense was ignited and used in a room of 100 square meters, and the volatilization rate of its active ingredients was determined to be 80%, and the fumigation time was 2 hours, which could completely prevent mosquitoes.

Embodiment 3

[0020] The base materials and additives in this example include by weight: 90 parts of charcoal powder, 18 parts of starch, 25 parts of pyrethrin extraction residue powder, and 4 parts of dextro-trans allethrin-rich materials. , to make mosquito coils. 15 grams of the incense is ignited and used in a room of 120 square meters, and the volatilization rate of its active ingredients is determined to be 78%, and the fumigation time is 3 hours, which can completely prevent mosquitoes.

Abstract

A quickly burning mosquito-repellent incense is prepared from charcoal powder (60-90 wt.%), adhesive (carboxymethylcellulose sodium, sodium alginate, or starch) (3-20 wt.%), wood poder and pyrethrin dregs powder (5-25 wt.%) and allethrin (0.5-4 wt.%). Its advantages are high volatilizing rate up to 75-80%, quickly taking its effect and less environmental pollution.

Description

technical field [0001] The invention relates to a mosquito-repellent incense, in particular to a fast-burning mosquito-repellent incense, and belongs to the technical field of pesticides and preparation thereof. Background technique [0002] At present, mosquito coils sold on the market are basically divided into two forms: burning mosquito coils and electric mosquito coils. The composition of mosquito coils is mainly powder of pine, fir or its shrubs, supplemented by adhesives and other mosquito repellent additives are added to form tablets. Such traditional mosquito coils have been used for many years. Since mosquito coils generate smoke when they are burned or heated by electricity, recent scientific experiments have shown that the smoke has no effect on repelling mosquitoes. The real disinfecting effect is the organic additives in mosquito coils. The current method of using mosquito coils requires about 8 hours to ignite or electrically heat. Due to the large amount of ...
