Description
Technical field
The invention belongs to antibacterial phase-change material and its preparation field, in particular to a kind of antibacterial phase-change microcapsule and its preparation
Method.
Background technique
Phase-change microcapsule is that phase-change material is wrapped in wall shell using microcapsules technology, forms small particle, thus
It prevents phase-change material from revealing, phase-change material is prevented to contact with the external world.Using the phase-change material of package phase is occurring for phase-change microcapsule
The characteristic for storing and releasing energy when transformation achievees the purpose that control material temperature, in food, weaving, medicine, coating, makeup
Product, transport, electronic device etc. are widely used.
Current its function of existing phase-change microcapsule is relatively single, is unable to satisfy that people are diversified to product function to be wanted
It asks, especially in daily textile or medical textile field, in constant same of the temperature for maintaining body temperature or use environment
When, bacterial growth or infection must be avoided as far as possible, this just proposes requirement to the antibiotic property of phase-change microcapsule.Chinese patent
CN106351017 provides a kind of microcapsules and preparation method thereof with mosquito repellent anti-bacterial heat storage temperature adjustment complex function, by phase transformation
The microcapsules that preparation has the temperature adjustment of mosquito repellent anti-bacterial heat storage are blended with the plants essential oil with mosquito repellent antibacterial functions for material, but it is used
Essential oil achievees the purpose that antibacterial, not persistently.Chinese patent CN108686262A provides a kind of sustained release based on double-walled microcapsules
The preparation method of antibacterial phase transformation medical dressing, using pretreated expanded perlite as carrier, after vacuum suction liquid state phase change material
In the chitosan layer of adsorption argentiferous, sodium alginate porous gel layer is re-formed, obtains double-walled sustained-release antibacterial phase-change microcapsule,
But it is porous material absorption phase-change material, and enthalpy is not high, and complex process.Chinese patent CN106351017A provides one
Kind has the microcapsules and preparation method thereof of mosquito repellent anti-bacterial heat storage temperature adjustment complex function, using composite core material (phase-change material and tool
Have the plants essential oil of mosquito repellent antibacterial) the mosquito repellent anti-bacterial heat storage temperature adjustment microcapsules using melamine resin as shell are prepared by in-situ polymerization,
But essential oil, which accounts for core material certain proportion, causes enthalpy not high, up to 81J/g.
Also there is the report of antibacterial phase-change microcapsule in pertinent literature.Geng et al (DOI:10.1016/
J.energy.2018.06.218 emulsifier) is made using styrene maleic anhydride copolymer and prepares phase-change microcapsule, is then deposited
Silver is deposited in surface of microcapsule, prepares silver-colored antibacterial phase-change microcapsule, enthalpy 170.2J/g.Wang et al (DOI:
It is 10.1016/j.energy.2018.06.118) that emulsified particle prepares the micro- glue of phase transformation using improved silica nanoparticle
Capsule, then using DEXTROSE ANHYDROUS as the reducing agent of silver ion in silica phase-change microcapsule surface reduction silver, preparation contains
Silver-colored antibacterial phase-change microcapsule, enthalpy 110.76J/g.But they use emulsifier and reducing agent substep preparation antibacterial phase transformation
Microcapsules cause preparation process cumbersome, complicated for operation, and microcapsules are both increased cost and also reduced by a large amount of silver coatings
Microcapsules enthalpy limits its industrial application.
