Problems solved by technology

Yet the mosquito-repellent incense that this method makes can not eliminate peculiar smell well, and simultaneously, artificial fragrance can not play better inhibitory effect, and insecticide content is on the high side
In addition, in actual operation, the process of this method is more complicated, and the processing time of anthracite is longer, which reduces the production efficiency

Embodiment 1

[0024] First, add 30g of charcoal powder, 60g of wood powder and 9.47g of natural wild chrysanthemum, crush them through a 100-mesh sieve, and mix them well. Then add 0.1g of starch and stir evenly. Then, the mixed paste is extruded into tablets through a tablet press, and the blank is punched into a spiral blank of mosquito coils with a punching machine, and then the spiral blank is put into a drying room and dried at 80°C for 4 hours , to obtain a dry body with a density of 0.7g / cm 3 . Subsequently, the dry compact is put into the spraying workshop and sprayed with 3 ml of ethanol solution of allethrin with a concentration of 0.01 g / ml. Finally, put the processed dry blank into a carton, shrink the film, and pack it into a box to obtain a burning mosquito-repellent incense. The resulting product number is 1.

Embodiment 2

[0026] First, add 45g of charcoal powder, 45g of wood powder and 7.67g of natural wild chrysanthemum, crush them through an 80-mesh sieve, and mix them well. Then add 0.4g of starch and stir evenly. Then, the mixed paste is extruded into a sheet by a tablet press, and the sheet is punched into a spiral billet of mosquito coils with a punching machine, and then the spiral billet is put into a drying room and dried at 60°C for 6 hours , to obtain a dry body with a density of 0.7g / cm 3 . Subsequently, the dry compact is put into the spraying workshop and sprayed with 33 ml of ethanol solution of transfluthrin with a concentration of 0.01 g / ml. Finally, put the processed dry blank into a carton, shrink the film, and pack it into a box to obtain a burning mosquito-repellent incense. The resulting product number is 2.

Embodiment 3

[0028] First, add 60g of charcoal powder, 30g of wood powder and 8.98g of natural wild chrysanthemum, crush them through a 120-mesh sieve, and mix them well. Then add 0.3g of starch and stir evenly. Then, the mixed paste is extruded into a sheet by a tablet press, and the sheet is punched into a spiral billet of mosquito coils with a punching machine, and then the spiral billet is put into a drying room and dried at 50°C for 8 hours , to obtain a dry body with a density of 0.8g / cm 3 . Subsequently, the dry billet was put into the spraying workshop and sprayed with 20 ml of an ethanol solution of perfluthrin with a concentration of 0.01 g / ml. Finally, put the processed dry blank into a carton, shrink the film, and pack it into a box to obtain a burning mosquito-repellent incense. The resulting product number is 3.

Abstract

The invention relates to combustion mosquito coil incense and a preparation method thereof. The combustion mosquito coil incense comprises the following components in proportion by weight: 30-60% of carbon powder, 30-60% of vegetable powder, 0.1-0.5% of starch, 0.02-0.5% of pyrethroid and 5-10% of natural wild chrysanthemum flower. The preparation method of the combustion mosquito coil incense comprises the following steps: crushing and fully mixing the carbon powder, the vegetable powder and the natural wild chrysanthemum flower to form a first mixture; adding the starch to the first mixture, and evenly stirring to form a second mixture; extruding the second mixture into slices, and stamping the slices into a spiral billet shape to form spiral billets; drying the spiral billets to obtaindried billets; and attaching the pyrethroid to the dried billets to obtain the combustion mosquito coil incense. The combustion mosquito coil incense of the invention has the advantages of stable combustion, small smoke quantity, fragrant odor and good mosquito repelling effect.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and in particular relates to a burning mosquito-repellent incense containing natural wild chrysanthemum components and a preparation method thereof. Background technique [0002] It is very common to use mosquito-repellent incense to repel mosquitoes in daily life in summer, and the types of mosquito-repellent incense are also increasingly diverse. Mosquito coils mainly include electric heating sheet mosquito coils, electric heating liquid mosquito coils, and burning mosquito coils. The electric heating sheet mosquito-repellent incense is a tablet made of repellent (killing) mosquitoes made of absorbable material as a carrier and added with an insecticide solution. It is used in conjunction with a constant temperature electric heater. At a certain heating temperature, it is evaporated by hot air Drugs, generally effective for 6 to 8 hours, so as to repel (kill) mosquitoes as a household san...
