Abstract
The invention relates to a medical high molecular bandage and a preparation method thereof. The preparation method comprises the following steps of: adding 5-30 parts by mass of macromolecule resin into 50-90 parts by mass of organic solution to obtain a resin solution; stirring the resin solution at a temperature of 30-70 DEG C and then adding 1-10 parts by mass of nanometer filler and 0.05-5 parts by mass of coupling agent into the solution; impregnating fiber cloth into the solution for 1-10 min and longitudinally stretching the fiber cloth impregnated with the resin solution; and finally, cooling and shaping the fiber cloth through cold air to obtain the medical high molecular bandage. The medical high molecular bandage prepared by the invention has the advantages of good mechanical property, heat resistance and excellent air permeability.
Description
Technical field
The present invention relates to technical field of material, specifically is a kind of medical polymer bandage and preparation method thereof.
Technical background
For a long time, plaster bandage is widely used in aspects such as orthopaedics external fixation, rehabilitation be orthopedic, but gypsum material exist density big, airtight, do not pass through defectives such as X ray and cracky, bring many inconvenience to treatment.Medical polymer bandage is on cloth, to soak a kind of high-performance binder of processing with macromolecular material; Since have in light weight, intensity is high, good permeability, X ray penetrance are good, patient feels many advantages such as comfortable; Progressively replace the conventional gypsum binder, mechanical property is low, the not high shortcoming of thermostability yet medical polymer bandage matrix material commonly used at present still exists.
Summary of the invention
Deficiency to prior art; The present invention provides a kind of medical polymer bandage and preparation method thereof; The present invention adopts nanometer inorganic filler that the medical polymer bandage matrix material is carried out modification, and prepares thus and have the better new medical AGMA of combination property.
The present invention realizes that the technical scheme that purpose adopts is:
A kind of method for preparing of medical polymer bandage; Comprise the steps: that each components in mass portion counts meter, 5～30 parts of macromolecule resins are added in 50～90 parts of organic solvents to being made into resin solution, stir down at 30 ℃～70 ℃; Add 1～10 part of Nano filling and 0.5～5 part of coupling agent again; After stirring, cloth is immersed in the above-mentioned solution 1～10 minute, and this cloth that is impregnated with resin solution is carried out longitudinal stretching; Its draw ratio is 1～3, with cold wind its cooling and shaping is got final product at last.
Said macromolecule resin is polycaprolactone, polyurethane elastomer, ethane-acetic acid ethyenyl ester or using trans-polyisoprene.
Said organic solvent be in acetone, ethyl acetate, oxolane, butanone, chloroform, dichloromethane, toluene, Ethyl formate or the butyl acetate any one and more than.
Said Nano filling is nano imvite, nano silicon or nano-calcium carbonate.
Said coupling agent be in silane coupler, titanate coupling agent or the aluminate coupling agent any one and more than.
Said cloth is cancellated glass fabric.
Compared with prior art, the present invention has following advantage and beneficial effect:
(1) it is composite modified to utilize inorganic nano-filler that the macromolecule resin matrix is carried out, and through the nano-dispersed of inorganic filler in matrix, realizes resin mechanical property and stable on heating raising;
(2) adding of a small amount of Nano filling on the basis of improving material mechanical performance, changes little to material proportion;
(3) the support frame material glass cloth of binder has regular RF, adopts stretch processes that resin matrix is evenly distributed on the backing material, thereby obtains the even gap structure of good air permeability.
