Description
Technical field
The present invention improves the preparation method of a kind of mosquito incense, the preparation method of a kind of microcapsule mosquito incense.
Background technology
Radix Artemisia ordosicae, for the perennial wild herb of Compositae artemisia, the Radix Artemisia ordosicae quintessence oil physiologically active ingredient kind therefrom extracted
More, many of which monoterpene and sesquiterpenoids chemical substance all have antibacterial and anophelifuge, its antibacterial anti-as a kind of natural, environmental protection
Mould dose, meet the green consumption idea of people.But owing to the unstability of Radix Artemisia ordosicae quintessence oil makes its duration of efficacy short, limit
Application.Microcapsule technology is by being coated with essential oil so that it is slowly discharge through cyst wall, improves the pressure-sensitive of Radix Artemisia ordosicae quintessence oil
Property, heliosensitivity and thermal sensitivity, improve product specification and added value.
Microcapsule technology is to utilize a class material to be coated with by another kind of material as filmogen, forms microencapsulation
A kind of technology.Capsule size, generally in nanometer to micron order, along with the development of nano fabrication technique, prepares nanoscale grain
The microcapsule in footpath is widely studied.Microcapsule is usually the nucleocapsid structure of monolayer, and the core that cyst membrane is coated with can also be in many
Core shape, is wrapped in the material within microcapsule and is referred to as the capsule heart, active substance, core etc., and the coating film outside microcapsule is referred to as wall
Material, cyst wall, housing etc..Material is carried out micro encapsulation and can improve the stability of material, control the rate of release of core, improve
It is wrapped by the physical property of material, it is simple to process etc..
Gelatin is that one is effectively protected colloid, can stop the gathering of crystal or ion, and have good biology
The compatibility, biodegradable and moulding property, be to prepare wall material raw material important in microcapsule.Prepare gelatin-microcapsule generally to select
Method have Simple coacervation, complex coacervation, freeze-drying, spray drying method etc..Carboxyl on gelatin side chain, amino and
Hydroxyl makes it have higher chemism, can be modified gelatin by various methods, obtains many and had both retained gelatin
Excellent properties, has again the new material of new features.Leng Yan state etc. utilizes acrylamide that gelatin carries out graft modification, with list
Microcapsule prepared by coacervation, research shows that the increase with grafted gelatin molecular weight, Microcapsules Size distribution broaden, along with connecing
The reduction of branch gelatine molecular weight, the particle diameter distribution of microcapsule is more concentrated, and tends to normal distribution.By other natural polymer
Sub-material is blended with gelatin, significantly improves its biocompatibility, controlled degradation, such as chitosan etc..
Existing technology is fast to Radix Artemisia ordosicae rate of release, and antibacterial repelling effect is the best, and the present invention improves its antibacterial anophelifuge
Effect.
