Abstract
The invention discloses a preparation process of microcapsule slow-release type essential oil mosquito repellent gel, and particularly relates to the technical field of articles for daily use, which comprises the following steps of preparing 10-20 parts of plasticizer, 10-25 parts of compound plant essential oil, 5-10 parts of initiator, 5-8 parts of emulsifier, 80-90 parts of deionized water, and 240 parts of calcium chloride aqueous solution 230-containing materials with the mass percentage concentration of 10%. According to the invention, the plant essential oil is compounded, the double-layer slow-release microcapsules are prepared, the plant essential oil is processed into a sheet of 2g, the sheet is pasted with the gum and the release paper and can be pasted on the surfaces of articles such as a wardrobe, a bedside or a backpack, so that the mosquito-repellent sheet prepared by the invention is convenient to use and carry.
