Elastic bandage and preparation method thereof
Technical field
The present invention relates to a kind of binder, relate in particular to a kind of elastic bandage and preparation method thereof.
Background technology
On present market in the binder of all the band glue that can see, can be divided into two kinds, a kind of is not have any elastic force and the binder that has glue, papery non-woven fabrics adhesive tape such as motion adhesive tape, the use of extension saline, this binder is without any elasticity, because do not realize and the synchronous variation of physical disfigurement that the comfort during use is not enough; Another kind of for warp-wise has the binder that the elastic force broadwise does not have elastic force and has glue, as self-adhering fascia etc.Chinese patent CN1827177A discloses " a kind of self-adhesive elastic bandage and manufacture method thereof ", and the glue of this Elastic bandage adopts synthetic rubber, and its feature is to have only binder self bonding mutually, and not ixoderm skin, hair, medicated clothing etc.Can only uninterruptedly twine, just can cling with the handing-over that reaches lining and lining, can't directly stick in human body surface, though synthetic rubber is lower than common natural emulsion anaphylaxis simultaneously, because it can only be dissolved in the gasoline, the risk of production is very high.In the gluing mode, the transfer that this patent is mentioned be coated with come down to irrealizable: principle is to produce self-adhering fascia if use to shift the method that is coated with, be coated with the method technology and can find from transfer, transfer is coated with method can only realize the single face gluing, and self-adhering fascia generally requires the lining surface can not be too smooth, too leveling gum point just can not evenly scatter on the surface, if shift the method that is coated with, the glue of irregular lining and transfer all can't be realized the handing-over of smooth driving fit, just can't realize that also glue is transferred to lining from medium, if just single face shifts gluing, single face has self-adhesive not realize that lining and lining are bonding, thus do not become self-adhering fascia, and if increase glue consumption or change the kind of glue, so certainly will will bonding human body, can not be self-adhering fascia.
If the binder four direction all has elastic force and has viscosity glue, so it use will be more comfortable and convenient, but the occupation mode of self-adhering fascia is that binder is wrapped in body surface, give certain pulling force and make that certain pressure is arranged between glue and the glue, at this moment need the size and shape of lining relatively stable, otherwise can't fix.And if there is elastic force at the four sides, when warp direction stretching advances, broadwise will indentation, in this case, the viscosity that self-adhesive is extremely low promptly can only glue and the adherent characteristic of glue, just can't fix the contraction distortion that produces owing to lining elastic force, also just fail to stick, can't realize that there is elastic force at the four sides.Therefore will produce four direction all has elastic force and has viscosity glue, can be bonding securely with human body, when peeling off, do not leave remaining Elastic bandage product and just face following technical barrier: one at human body surface, if make lining have very high elastic force, can not be less than 180%, and accomplish that four direction all has, just must adopt the enough linings of elasticity, but the molding of this elastic fabric is difficulty relatively, it is irregular to produce gluing when gluing, and on technology controlling and process, when lining is drawn back gluing, just be easy to generate the space, glue can see through lining and arrive another side, thereby does not have workability; Two, need to solve the not enough problem of fastness that combines of the glue that produces in the gluing process and lining, this problem of bringing is in use, when binder uses when peel off the object or person surface, have glue and come off from the binder surface and be bonded at the object or person surface, very trouble.
Summary of the invention
First purpose of the present invention provides a kind of brand-new binder product, and its longitude and latitude all has the elastic force of height, scribbles on it to be suitable for the glue that human body uses, and uses splendid comfortableness.
The technical scheme that realizes first purpose of the present invention is a kind of elastic bandage, comprises lining and is covered in glue layer on the lining; Described lining is that longitude and latitude all has spandex silk knit lining; Described glue layer and lining are combined closely, and glue is a kind of in zinc oxide, PUR, the medical acrylic acid glue; Described elastic bandage warp-weft two-way all has elastic force.
Described elastic bandage warp-weft two-way elastic force all 〉=300%.
Described glue layer close adhesion is in the one side of lining, and glue is discontented to be applied to lining, makes described elastic bandage have breathability.
Also comprise the silicone oil paper that covers on the glue layer.
Second purpose of the present invention provides a kind of manufacture method of elastic bandage, and this method can be produced the elastic bandage that longitude and latitude all has elastic force and glue and lining strong bonded.
The technical scheme that realizes second purpose of the present invention is a kind of manufacture method of elastic bandage, comprises following steps:
1. lining is selected: adopt longitude and latitude all to have spandex silk knit lining;
2. gluing: adopt directly to be coated with or to shift the one side gluing of the mode that is coated with to lining;
3. oven dry: will have the lining oven dry of glue;
4. rolling: after covering one deck silicone oil paper on the glue layer, carry out rolling.
Described the 2. the step adopts and shifts the concrete steps that are coated with and be:
A, will dilute good medical acrylic acid glue and be coated on the silicone oil paper;
B, draw back lining is smooth, the silicone oil paper and the lining pressurization that will have glue again are compound, glue is transferred on the lining, and is embedded in the lining;
C, silicone oil paper is removed.
2. described the when going on foot gluing, earlier according to the glue face decorative pattern die sinking head of client's needs.Described the 2. the step adopts and shifts the concrete steps that are coated with and be: at first will dilute the medical acrylic acid glue of getting well and be coated on the silicone oil paper according to the shape of die head; Draw back lining is smooth then, the silicone oil paper and the lining pressurization that will have glue again are compound, glue is transferred on the lining, and is embedded in the lining; Again silicone oil paper is removed.
Described the 4. the concrete steps in step be: on winder, add dise knife, the elastic bandage that covers on the glue layer behind one deck silicone oil paper cut monovolume rolling more synchronously.
After having adopted technique scheme, the present invention has following good effect: (1) elastic bandage of the present invention is owing to be that the four sides all has elastic force, thereby after fitting, can change the shape of binder according to the shape of human body surface skin with human body, have splendid comfortableness.
(2) after being attached to skin surface after common Elastic bandage stretches, binder is in stress always, along with the prolongation of service time, the phenomenon that warps can occur in edge.And elastic bandage of the present invention has the elastic force at longitude and latitude four sides, and stressed more even, tension force is also more stable, and the docile property after the applying is fine, and the phenomenon that warps is well below through bullet or there is not the bullet product.
(3) common binder is fitted in the human synovial position, elbow joint for example, if the user fits when the arm elongation state, when elbow is crooked, the surface area of elbow joint just increases, if through bullet or there is not the bullet product, the binder with the vertical direction of arm will collapse out so, thereby leave coating surface, influence is used.Elastic bandage of the present invention four sides all has elastic force, can change synchronously according to the variation of human body with the binder of arm vertical direction, does not collapse state thereby can not produce binder.
(4) existing lining generally can adopt cotton or cotton base material, and this is because of all Comparatively speaking more coarse on cotton base material yarn surface, gluing easily.And if the bonding not firm of glue and lining when producing with common process, will take place, thereby glue is separated with lining in more comfortable, the more slick lining of employing.Elastic bandage simultaneously of the present invention requires and the human body good bond, thereby requires glue to become bulk to be bonded on the lining continuously, and the another side of lining does not allow the glue existence.For reach simultaneously comfortable, bonding firmly and lining have only one side glue again, when adopting medical acrylic acid glue and transfer, the present invention is coated with method, thereby can guarantee the fastness that combines with lining, can solve common glue and lining to combine fastness not enough, when peeling off bonded surface, have residual problem, guaranteed in use do not come unstuck and permanent superpower viscosity in also guaranteed hypoallergenic with human body, and binder more smooth exquisiteness, comfortable feel.
The specific embodiment
(embodiment 1, Elastic bandage)
The elastic bandage of present embodiment comprises lining, be covered in the glue layer on the lining and cover silicone oil paper on the glue layer; Lining is that longitude and latitude all has spandex silk knit lining, thereby guarantees the elastic force of warp-weft two-way; The glue layer close adhesion is in the one side of lining, and glue is discontented to be applied to lining, makes described elastic bandage have breathability, and glue adopts zinc oxide.Elastic bandage warp-weft two-way elastic force all 〉=300%.
(embodiment 2, Elastic bandage)
Present embodiment is substantially the same manner as Example 1, and difference is that glue adopts PUR.
(embodiment 3, Elastic bandage)
Present embodiment is substantially the same manner as Example 1, and difference is that glue adopts medical acrylic acid glue.
(manufacture method of embodiment 4, Elastic bandage)
Present embodiment specifies the manufacture method of embodiment 3.
1. lining is selected: for comfort level and the suitable strong elasticity that guarantees human body, selected lining should have elasticity and thickness should be approaching as far as possible with the thickness of human body skin, like this, after fitting in the human body surface, could guarantee comfortableness, so present embodiment adopts longitude and latitude all to have spandex silk knit lining.
2. gluing: this is the committed step of present embodiment, because it is relatively more difficult in molding that longitude and latitude all has the lining of elastic force, when spreading knife can make the lining distortion when streak on the surface, thereby thereby make the inhomogeneous standard of producing that does not meet use of product glue face, thereby present embodiment adopts the method that is coated with that shifts, in this state, lining is smooth and evenly stressed, the fold that can not produce, the glue face also can be even, owing to need not draw back the lining gluing, do not have the space on the lining simultaneously, glue can not be penetrated into another side.Specifically, this step is: at first according to the glue face decorative pattern die sinking head of client's needs, will dilute good medical acrylic acid glue then and be coated on the silicone oil paper according to the shape of die head, medical acrylic acid glue is discontented to be applied on the lining, thereby makes binder have breathability; Draw back lining is smooth, the silicone oil paper and the lining pressurization that will have glue again are compound, glue is transferred on the lining, and is embedded in the lining again; At last silicone oil paper is removed.
3. oven dry: will have the lining oven dry of glue; With the oven dry of the moisture in the medical acrylic acid glue of dilution, remaining pure acrylic acid glue.Owing to contain moisture when combining with lining, by oven dry, glue can have certain infiltration on lining, guaranteed the bonded firm degree of glue and lining, avoided because lining is a chemical fibre, with the not enough problem of glue bonding force, in use, produce degumming phenomenon in the time of just can after use, not peeling off.
4. rolling: carry out rolling after covering one deck silicone oil paper on the glue layer, concrete steps are: add dise knife on winder, the elastic bandage behind covering one deck silicone oil paper on the glue layer is cut monovolume rolling more synchronously.The benefit that adds one deck silicone oil paper is not only and is user-friendly to, and has also guaranteed the stationarity of lining simultaneously, is unlikely to because be four sides bullet and being out of shape.Because there has been paper at the surface with glue material back side, the edge of a knife and divides the product tangent plane that cuts out smooth with regard to smooth and easy and non cohesive gel when cutting like this, and itemize is accurate.After this length on request is divided into desired monovolume dress and gets final product.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
