Embodiment 1
[0061] The present embodiment provides a mosquito repellent sustained-release product, wherein the base material is porous polystyrene (macropore refers to a hole with a pore diameter greater than or equal to 50 nm) whose macropore volume accounts for more than 82% of the total pore volume, and the synthetic porous polystyrene The ethylene emulsion is composed of the following components in mass percentage: 15.3% styrene, 1.6% divinylbenzene, 0.5% azobisisobutyronitrile, 1.6% emulsifier, and 81.0% deionized water.
[0062] The size of the molding die is a cylindrical aluminum container with a diameter of 55mm and a thickness of 3mm. The product is made according to the process flow. The weight of the porous polystyrene is 2g, and the pyrethroid is loaded with 300mg to obtain a mosquito repellent slow-release product.
Embodiment 2
[0064] This embodiment provides a mosquito repellent sustained-release product, wherein the base material is porous polystyrene whose macropore volume accounts for more than 82% of the total pore volume, and the emulsion of the synthesized porous polystyrene consists of the following groups in mass percentage: Composition: styrene 17.5%, divinylbenzene 2.0%, azobisisobutyronitrile 0.6%, emulsifier 1.8%, deionized water 78.1%.
[0065] The size of the molding die is a cylindrical aluminum container with a diameter of 55mm and a thickness of 3mm. The product is made according to the process flow. The weight of the porous polystyrene is 2g, and the pyrethroid is loaded with 300mg to obtain a mosquito repellent slow-release product.
Embodiment 3
[0067] This embodiment provides a mosquito repellent sustained-release product, wherein the base material is porous polystyrene whose macropore volume accounts for more than 82% of the total pore volume, and the emulsion of the synthesized porous polystyrene consists of the following groups in mass percentage: Composition: styrene 10.6%, divinylbenzene 1.1%, azobisisobutyronitrile 0.5%, emulsifier 2.7%, deionized water 85.1%.

Abstract
The invention relates to the technical field of daily chemical products, in particular to an anti-insect slow-release product and a preparation method thereof. Adjusting and optimizing the pore structure of the substrate through the method of the present invention not only makes the pore structure of the substrate relatively developed, but also increases the migration rate of the medicament inside the substrate to the outside, and can also greatly reduce the residual rate of the medicament in the substrate to obtain a more Excellent slow release properties. The preparation of the base material by the method of the invention can achieve the goal of regulating the release rate of the drug according to different demand conditions. The mosquito repellent sustained-release product prepared by the invention can be placed indoors or outdoors at a temperature of 20-35° C., and can provide continuous mosquito repellent effect for more than 30 days without electrification or heating. The mosquito repellent slow-release product prepared by the invention can maintain a stable product structure under the attack of a small amount of rainwater or domestic water, reduces the loss rate of the mosquito repellent, and has good environmental friendliness.
Description
technical field [0001] The invention relates to the technical field of daily chemical products, in particular to an anti-insect slow-release product and a preparation method thereof. Background technique [0002] As a sanitary pest, mosquitoes are intermediate hosts of pathogens such as dengue fever, malaria, and yellow fever. In recent years, people's outdoor activity time has increased significantly with the improvement of socioeconomic level, so they are more likely to encounter the problem of mosquito bites. Disc-type mosquito-repellent incense needs to be ignited to release mosquito-repellent ingredients, which poses a burn and fire hazard. Electric mosquito-repellent liquid and electric mosquito-repellent sheets require extra electricity to release mosquito repellent ingredients, which is less convenient to use. The smear-type mosquito repellent has a short action time and needs to be applied repeatedly, and the mosquito repellent effect is easily affected by sweat. ...
