Description
Technical field
The invention belongs to medical bandage manufacture field, and in particular to a kind of preparation side of filler for medical bandage manufacture
Method.
Background technology
Medical polymer bandage is the common used material for promoting conditions of patients to recover, and is made to improve mechanics of above-mentioned material etc.
With quality, inorganic filler components are generally added into raw material during fabrication, and composition be present in existing most inorganic filler components
It is single, the problems such as using quality-improving unobvious for bandage.And existing most bandages are just discarded after use, in natural bar
Degraded in part slow, be unfavorable for environmental protection.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of preparation side of filler for medical bandage manufacture
Method.
The present invention is achieved by the following technical solutions：
A kind of preparation method of filler for medical bandage manufacture, comprises the following steps：

The Potassium Hydrogen Phthalate solution that cerium solution and concentration are 0.55mol/L by volume 1：3, which carry out mixing, is put into reactor, so
After adjust its solution ph as 7.5 ~ 8.0, heating water bath then is carried out to it again, the temperature for keeping heating is 80 ~ 85 DEG C, constantly
Suction filtration separation is carried out to the sediment of reaction gained after 1 ~ 2h of stirring reaction, dried after finally cleaning one time with distilled water to constant weight
.
Further, step（4）Described in drying box in drying temperature control be 80 ~ 85 DEG C.
Using montmorillonite as main matrix composition the special filler of structure has been made, by being surface-treated, at calcining in the present invention
After reason, the specific surface area and characterization of adsorption of montmorillonite are obviously improved, and are laid a good foundation for follow-up processing, are then carried out
Special immersion modification, the silane coupler composition of addition effectively improve point of the montmorillonite in macromolecule matrix material
Dephasing capacitive, improves its mutual bond strength, and the chinaberry Aqueous extracts of addition are that chinaberry is put into boiling water to decoct
Boil and form, active ingredient therein is adsorbed to be fixed in montmorillonite so that montmorillonite has good antibacterial activity, Jin Erti
The safety in utilization and quality of bandage are risen, the auxiliary agent of addition is a kind of cerium-phthalic acid complex, utilizes rare earth element
Special energy jump effect, the absorption to photon can be strengthened, and then cause bandage that there is good degradability.
The present invention has advantages below compared with prior art：
Filler produced by the present invention can effectively lift the antibiotic property of bandage, mechanical characteristic, degradability etc., improve making for bandage
With quality, have good value for applications.
