Antibacterial anti-acarien microcapsule and preparation method thereof

Abstract

The invention relates to an antibacterial anti-acarien microcapsule and a preparation method thereof. An antibacterial anti-acarien liquid is used as a core material, and the methyl methacrylate added with nano-silver particles is used as a wall material. The preparation method is as follows: (a) shearing a water phase under a high-speed shearing machine, adding an oil phase and stirring to obtain uniform emulsion; (b) adding methyl methacrylate and an initiator in the emulsion obtained in the step (a), stirring, and then adding a silver nitrate solution; (c) cooling the liquid obtained after the reaction of the step (b), standing, and then washing, rinsing and drying precipitate to obtain the antibacterial anti-acarien microcapsule. At early stage, the microcapsule is used for inhibiting the crosslinking of polysaccharide chain and tetrapeptide by using the formation of the Ag<+> interfering bacteria cell wall so that the cell wall is out of completeness, the protection effect to the osmotic pressure is lost, the bacteria are damaged and dead, and the added silver nitrate solution is embedded in the micropore of the microcapsule wall to reduce the size or number of the micropore; at late stage, the cleanness of the fabric can be continuously maintained through the slow releasing of the antibacterial anti-acarien liquid.

Description

technical field [0001] The invention relates to the technical field of textile manufacturing, in particular to an antibacterial and anti-mite microcapsule. technical background [0002] Dust mites are a kind of mites, which belong to the phylum Arthropoda. They are small in size, generally about 0.1-0.5mm in size, so they cannot be seen with the naked eye. It is ubiquitous in the home environment, such as parasitizing on bedding, carpets, cushions, clothing, plush toys and other articles, and feeds on the dander shed by the human body with the help of fungi. It is most suitable to live in an environment with a temperature of 20-30°C and a relative humidity greater than 55%. Therefore, modern rooms equipped with air conditioners, carpets, and better airtightness provide it with a good living and breeding environment. According to reports, more than 75% of the home environment in my country harbors dust mites. The main harm of dust mites is to cause allergic diseases such as...
