Description

One kind transfusion rubberizing and preparation method thereof
Technical field
The invention belongs to macromolecule adhesive technical field, more particularly it relates to a kind of transfusion rubberizing and its system Preparation Method.
Background technology
Medical infusion is attached to when being treated to patient infusion, is fixed woven hose and transfusion needle, is protected transfusion needle mouthful not infected, What woven hose and transfusion needle were fixed during transfusion is too tight, when infusion paste is taken off, is easy for driving transfusion needle mouthful, gently then to patient with Carry out pain, it is heavy then cause infection and needle point to scratch skin, if woven hose and transfusion needle fix it is too loose, easily cause loosening, nothing Method plays fixed fixed effect.
Pressure sensitive adhesive is to bond firm adhesive with adherend by a class need to only apply slight pressure.Due to pressure sensitive adhesive tool Have certain tack and hold viscosity, and in the case of free of contamination can Reusability, after stripping to by maxxaedium without dirt The features such as dye, it is widely used to many necks such as electronic isolation, electronic component processing, enlarged color photograph, automotive trim and medical treatment Domain.Wherein, pressure sensitive adhesive is always popular problem in medical patch field, and the selection correctness of pressure sensitive adhesive is to be related to product Using the principal element of success or failure.Medical pressure-sensing glue adhesive agent is very high to performance requirement, and it must is fulfilled for:(1)To various skins Type(Dry, moisten)Can be bonded very well;(2)Can remove without staying any residue or not causing skin injury, not stimulate skin. The pressure sensitive adhesive in field of medicaments application mainly has polyurethanes, acrylic compounds, silicone rubber kinds, thermoplastic elastomer (TPE) and natural at present Rubber etc..All these pressure sensitive adhesive is all hydrophobic polymer, and the compatibility with skin is not good enough, gas permeability and water imbibition Difference, can produce seeping phenomenon, skin maceration even to whiten, damaged to skin when being attached for a long time on skin.
Accordingly, it would be desirable to develop a kind of preferable bioadhesion performance, good permeability, without sensitization, noresidue and very strong The transfusion rubberizing of holding power.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of transfusion rubberizing and preparation method thereof, is applied using the transfusion rubberizing The infusion paste that cloth is made has preferable bioadhesion performance to skin, and energy relatively good moisture absorbing and sweat releasing will not when pasting and taking off Cause pain, have no cull and leave, stimulation is not produced to skin.
In order to solve the above problems, the invention provides one kind transfusion rubberizing and preparation method thereof.
In order to realize foregoing invention purpose, this invention takes following technical scheme:
One kind transfusion rubberizing, the transfusion rubberizing is prepared from by the raw material including following percentage by weight:
SBS 20~40%
Tackifier 30 ~ 60%
HO-SBS 5~10%

In one embodiment, the SBS is the mixture of different molecular weight, wherein, number-average molecular weight be 5000 ~ Account for SBS gross weights the 10 ~ 25% of 20000, number-average molecular weight is account for SBS gross weights the 35 ~ 50% of 30000 ~ 85000, counts equal Account for SBS gross weights the 25 ~ 40% of molecular weight 90000 ~ 110000.
In one embodiment, the tackifier are the one kind in polyethylene, polypropylene, polystyrene and polyisobutene Or it is various.
In one embodiment, in the HO-SBS, the grafting rate of hydroxyl is 25-40%.
In one embodiment, in the HO-SBS, the grafting rate of hydroxyl is 33%.
In one embodiment, the polyaminoacid is in polylysine, poly-aspartate and Polyurethane-epoxy resin Kind.
In one embodiment, the polyaminoacid is polylysine.
In one embodiment, the antioxidant is BHT or DLTP.
Another object of the present invention is to provide the method for preparing transfusion rubberizing, including following methods:
1)First by naphthenic oil, antioxidant input stainless steel cauldron, after being warming up to 120 ~ 130 DEG C, SBS and HO- is added SBS, and by temperature of reaction kettle control within 140 DEG C;
2)After tackifier and polyaminoacid is put into after SBS and HO-SBS all dissolving, by stainless steel cauldron temperature control Stirred 30 ~ 60 minutes within 155 DEG C;
3)By reaction kettle for vacuumizing to -0.085Mpa, packed after discharging, cooling.
In one embodiment, the step 2)In temperature be 140 DEG C.
The present invention based on SBS, because SBS is nonpolar and hydrophobic polymer, using HO-SBS to SBS and polar material The compatibility of matter is improved, while-the NH on the polyaminoacid for adding2- OH can be formed firmly in HO-SBS with-NH Hydrogen bond, so as to improve the bioadhesion performance of pressure sensitive adhesive.Compared with prior art, transfusion rubberizing of the invention has preferable Bioadhesion performance, good permeability, the transfusion rubberizing without sensitization, noresidue and very strong holding power.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to described further below.
