Description

One kind easily tears medical proof fabric
Technical field
The present invention relates to a kind of medical proof fabric, more particularly to one kind easily tears medical proof fabric.
Background technology
Adhesive plaster is a kind of sticking plastic products adhesive plaster, and common adhesive plaster includes medical proof fabric, insulating tape etc., its Middle medical proof fabric has good permeability, and nontoxic nonirritant, and Nature comparison is gentle, has good viscosity, is usually used in Fixed injection needle, wrapping etc.；But when existing medical proof fabric is taken off from adult, it often can all experience and " tear for a moment The pain split ", if so this adhesive plaster is taken off from the tender and lovely skin of baby, it is likely that skin can be damaged, it is also possible to can cause When medical complaint and dispute event, certain negative effect is caused to medical institutions.
In the prior art, there is also the adhesive plaster being much easy to tear off, in Application No. CN201510781909.X A kind of novel medical proof fabric of state's patent, such adhesive plaster good permeability is environmentally protective, and is easy to tear off after being attached on human body, Some feeling of pains will not be produced to human body.
But with time change, viscosity has significantly to be reduced existing easily openable medical proof fabric, waits until certain time Afterwards, since adhesive plaster viscosity is too small, it can be separated with human body automatically, can not just play fixation, it is often necessary to repeatedly paste, It is cumbersome and time consuming, or even influence treatment results.
The content of the invention
In view of the deficiencies of the prior art, the present invention intends to provide one kind easily to tear medical proof fabric, the medical adhesive After cloth is pasted on human body, it is easy to tear, and keep stronger viscosity in a long time, will not mutually be taken off with human body automatically From.
To achieve the above object, the present invention provides following technical solution：One kind easily tears medical proof fabric, including following weight Part composition：

Tert-pentyl alcohol bismuth：2 parts；
N, N- dibutyl -1,3- propane diamine：3 parts；
Sodium cellulose glycolate：1 part；
Zinc oxide：2 parts；
Water：50 parts.
The coupling agent is 3-aminopropyltriethoxysilane.
The crosslinking agent is cumyl peroxide.
The emulsifying agent is two (2- ethylhexyls) amine.
The solubilizer is ethoxylated dodecyl alcohol and the mixture of ethylene oxide, its mass ratio is 1:1.
The antiseptic is the mixture of glycerin monostearate, potassium sorbate and povidone iodine, its mass ratio is 2:1: 2。
The plasticizer is o-phthalic acid dibutyl ester.
The waterproofing agent is (3,3,3- trifluoro propyls) trimethoxy silane.
The antioxidant is N-N'- diphenyl-p-phenylenediamines and the mixture of 4- tert-butyl catechols, its mass ratio is 1:2。
A kind of preparation method for easily tearing medical proof fabric：
The first step：The processing of cloth material, non-woven fabrics progress bleaching is bleached cloth, then poured into modified working solution first In the stock tank of starching machine, control and roll point pressure for 3500~4500 kilograms, above-mentioned bleach cloth is passed through with 8~18 meters of speed per minute Roller mangle, pick-up rate is 60~80%, then by 90~110 ° of preliminary dryings of cylinder about half a minute, through tenter expanding to open width Width, enters drying tunnel, and by drying tunnel at 170~195 DEG C, drying time is about 1-5 minutes, that is, obtains the modification nonwoven as base fabric Cloth；
Second step, prepares rubber cement, and 20-50 parts of sheets are given birth to natural rubber block is rolled into radish filiform or thin slice through rubber mixing machine Shape, is dipped in 30-80 parts of mass ratioes as 2:It is abundant that swelling is allowed in 1 gasoline and the mixed liquor of toluene, obtains raw rubber swelling thing, so The 3-5 parts of glyceryl tristearates as softening agent are added afterwards, add 5-20 parts of coumarone indene resins, stir 5-20min, then Sequentially add carbon black, magnesia, coupling agent, crosslinking agent, emulsifying agent, solubilizer, antiseptic, plasticizer, waterproofing agent, antioxidant and Stabilizer, continues to stir 30-60min, so as to obtain rubber pressure-sensitive adhesive slurry；
3rd step, rubber cement coating, the rubber cement obtained in second step is placed in the rubber cement groove before coating machine painting drum, It is 0.1~0.25mm to control cylinder gap, makes base fabric slowly by roller, through drying, winding, cut-out finished product.
Beneficial effects of the present invention：One kind easily tear medical proof fabric, using non-woven fabrics as base material, first by non-woven fabrics into Row bleaching is bleached cloth, and is then allowed and is bleached cloth by the roller mangle equipped with the starching machine for being modified working solution, then carries out cylinder Preliminary drying, is then dried by drying tunnel, you can obtains modification nonwoven cloth；Then rubber cement is prepared, the life with rubber mixing machine sheet Natural rubber block be made that radish is Filamentous or flake, be then dipped in the mixed liquor of gasoline and toluene, the matter of gasoline and toluene Measure as 2：1, the mixing liquid energy being configured so that makes raw rubber sufficiently be swollen, and after swelling completely, adds three glycerol stearates Ester is as softening agent and coumarone indene resin as tackifier, and coumarone indene resin is except playing tackifying effect, moreover it is possible to plays plasticizing, soft Change the effect with reinforcement, first stir certain time, add various auxiliary agents, you can obtain the pressure-sensitive rubber cement of rubber-type, finally use Pressure-sensitive rubber cement is coated onto in modified base fabric by coating machine, and the thickness of coating is 0.1-0.25mm, and the processing such as winding is then dried, It can be prepared by finished product；What the present invention made easily tears medical proof fabric, is not only easy to tear off, and patient will not produce feeling of pain when tearing, And after adhesion when 3 is small, still with good skin adherence, it will not be separated, ensure that with skin automatically The adhesive plaster can play fixation, play its due effect.
One of innovative point as the present invention, carries out the bleached non-woven fabrics that obtains and is handled with modification liquid, modified working solution is with water For solvent, by adding acrylic emulsion, tert-pentyl alcohol bismuth, N, N- dibutyl -1,3- propane diamine, sodium cellulose glycolate and oxidation Zinc these types material, can carry out good modification so that final system under the collective effect of these types of material to non-woven fabrics Easily tear medical proof fabric and be easy to tear off, patient will not be made to produce feeling of pain, more skin will not be caused to damage；Another innovation Point is that stabilizer have selected double [3- (triethoxysilane) propyl group] amine, magnesium stearate, lauryl sodium sulfate, bay imino groups Disodium beclomethasone and phosphorous acid three (2- ethylhexyls) ester this 5 kinds of materials；These materials it is mutually coordinated under, ensure that and easily tear Medical proof fabric has preferable viscosity, and viscosity change with time it is smaller, even if after when adhesion 3 is small on the skin, viscosity It is still relatively strong, good fixation can be played.
Antiseptic have selected glycerin monostearate, potassium sorbate and povidone iodine this 3 kinds of materials, in this 3 kinds of materials Under collective effect, obtained easily tearing medical adhesive tape has good antibacterial property, reduces the possibility to patient's secondary injury, more It is safe and healthy；It has selected N-N'- diphenyl-p-phenylenediamines and 4- tert-butyl catechols this 2 kinds of materials on antioxidant, this 2 kinds Under the collective effect of material, good anti-aging effect can be played, it is easy to aging to ensure that the present invention does not allow, can be placed for a long time, Easy to produce, transport and storage.
