Abstract
The invention discloses a kind of medical silica-gel adhesive tape, including gelatinous layer and cloth substrate, cloth substrate is the one in PE film, TPU membrane, foam and non-woven fabrics cloth material, and described adhesive tape is followed successively by the one in PE film, TPU membrane, foam, non-woven fabrics cloth material and gelatinous layer from outside to inside；The adhesive tape good permeability that the present invention provides, the laminating with skin is effective, is difficult to degumming, and can reuse during use.
Description
Technical field
The invention belongs to medical adhesive tape field, particularly to a kind of medical silica-gel adhesive tape and preparation method thereof.
Background technology
The adhesive tape commonly used in medical science and daily life at present is typically double-layer structure, and one layer is bottom cloth layer, and one layer is glue-line, sticker or base material coating layer because its each component difference be likely to cause adhesive tape airtight, affect comfort.
Adhesive tape in the market no doubt can reach preferably to fit at the beginning effect, but pro-skin not, usually can tearing skin and hair, impact uses impression, and position of fitting is the most movable, degumming phenomenon the most easily occurs；Existing adhesive tape is bad with the laminating effect of skin, easy degumming during use.
After adhesive tape uses once, cannot repeat owing to sticking effect is bad to paste, after normal tape uses once, it repeats sticking effect and can decline to a great extent, and usually can not use by secondary, can only reuse new adhesive tape, cause waste.
Therefore, it is badly in need of a kind of medical silica-gel adhesive tape and preparation method thereof and overcomes above-mentioned defect.
Summary of the invention
The main object of the present invention is to provide a kind of medical silica-gel adhesive tape and preparation method thereof, airtight to solve adhesive tape in prior art, bad with the laminating effect of skin, easy degumming during use, it is impossible to the problem repeating to paste.
For achieving the above object, the present invention is by the following technical solutions:
A kind of medical silica-gel adhesive tape, including gelatinous layer and cloth substrate, described gelatinous layer in parts by weight, is made up of following material:
Component A
30-50 part,
Component B
30-50 part,
Described component A is according to the mass fraction meter of component A, including following material:
Polysiloxanes 80%-90%,
Calcium carbonate 9%-19%,
Platinum water 0.5%-1%；
Described component B is one or more mixture mixed with arbitrary proportion in hydroxyl silicone, methyl silicone, silicon dioxide, polydimethylsiloxane.
Described cloth substrate is the one in PE film, TPU membrane, foam and non-woven fabrics cloth material.
Described adhesive tape is followed successively by the one in PE film, TPU membrane, foam, non-woven fabrics cloth material and gelatinous layer from outside to inside.
The preparation method of a kind of medical silica-gel adhesive tape, comprises the following steps:
Step A. is weighed, and weighs component A and component B in proportion；
Step B. stirs, and joins in container by component A and component B, and then stirring makes both react；
Step C. gluing, is coated onto the glue glue spreader prepared on non-woven fabrics cloth material.
The invention has the beneficial effects as follows: the gelatinous layer of the present invention have employed organosilicon composite glue as sticker, its breathability moisture retention is no less than hydrogel, to no skin irritation, drastically increases the biocompatibility of adhesive tape and adds its possible scope of application.Use novel organosilicon composite glue as sticker, because its gelatinous layer is different from general sticker, by under the attachment tear band on former use surface, thus the secondary use of adhesive tape will not interfered with when tearing.The present invention has effect of preferably fitting, gentleness, repeatable stickup, good permeability to skin.
PE film, TPU membrane can protect pasted position the most contaminated, and TPU membrane has good elasticity, thermostability, are ripe environment-friendly materials.PE with TPU with non-woven fabric compounded through special formulation, do not affect flexibility and the skin-friendly of non-woven fabrics, but also is that composite membrane has possessed certain ductility, decreases the tight sense of skin produced when general adhesive tape uses.If it is required, improve visual experience when user uses also by the color increasing PE Yu TPU.In addition foam is than PE Yu TPU more soft feeling, and tool water proofing property.The scope of application of the multiple base material non-woven fabric compounded silica gel adhesive tape that improve the present invention of collocation.
The adhesive tape good permeability that the present invention provides, the laminating with skin is effective, is difficult to degumming, and can reuse during use.
