Abstract
The invention discloses improved aqueous medical pressure sensitive adhesive bands of a kind of antiperspirant and preparation method thereof, are related to medical belt field.The improved aqueous medical pressure sensitive adhesive band of the antiperspirant coats the bottoming of water-base resin coating using the blended base fabric of polyester-cotton blend as substrate layer on one side, and the improved water-borne pressure sensitive adhesive water of antiperspirant is further coated on prime coat layer, compound with release layer after drying.The improved water-based glue layer formula of the antiperspirant is by weight are as follows: 65-85 parts of water-based glue, 1-3 parts of coupling agent, 0.5-2 parts of PH regulator, 15-30 parts of antiperspirant, 0.3-1 parts of levelling agent.The present invention, which obtains a kind of improved aqueous medical pressure sensitive adhesive band of antiperspirant, can be widely applied to the application with skin contact such as Medical bandaging, patient identifier stickup, bandage, traditional medical adhesive tape is eliminated because sweat gland of skin sweat is secreted, caused adhesive tape falls off to inconvenience caused by patient.
Description
Technical field
The invention belongs to medical belt field, the improved aqueous medical pressure sensitive adhesive band of specifically a kind of antiperspirant and its
Preparation method.
Background technique
In increasingly developed medical periphery and color spray consumptive material industry, the application of pressure sensitive adhesive tape is ubiquitous, such as:
Minor cut or wound debridement is fixed, Medical bandaging, bandage are pasted, patient identifier is pasted, injection needle is fixed, particularly is detained syringe needle and fixes
Deng.Medical belt is many kinds of currently on the market, but most of is all solvent type adhesive tape or adhesive plaster, is had to human body certain
Toxicity is stimulated, the allergic reaction that especially many people can generate brings more ailing pains.Either solvent type adhesive tape or water
Property adhesive tape, can all occur the problems such as viscous force decline in surface falls off to failure under water Wet Out, to medical medical procedures band
It is inconvenient to come.And it is pasted in medical belt in use, the moisture for soaking glue-line is mainly exactly human body sweat, and to spread around sweat gland
Formation is fallen off or crimping point, gradually falls off so as to cause adhesive tape.In medical belt, in particular for being pasted on skin for a long time
After the delay syringe needle fixation adhesive tape on surface falls off, greatly inconvenient and pain will cause to patient.
Summary of the invention
The present invention provides a kind of improved aqueous medical glue of antiperspirant for the deficiency of medical belt product on existing market
Band and preparation method thereof, for medical belt particularity that human skin is pasted require and existing market on major part adhesive tape
There are the problem of make improvement.Antiperspirant composition is added in glue, human sweat glands secrete the sweat gland of sweat in paste process
Point position, antiperspirant migrates under small range water wet environment to sweat pore cuticula and the gelled in conjunction with sweat, reduces
Reduce sweat continue to be secreted into surface layer, thus guarantee sweat will not long range diffusion and cause glue-line viscous force decline, lead to adhesive tape
It falls off.Though human epidermal sweat pore is more, shared body surface area is less, when antiperspirant need to only reach a certain amount of in glue, just
It can be reacted rapidly in sweat gland secretion, so antiperspirant is very small for tape-stripping influential effect, it can be by suitably mentioning
High glue application amount makes up.The above reactive moieties can greatly improve adhesive tape in the stickup time of human body surface, and all
Coating is water soluble green environment-friendly coating, and human body compatibility is strong.
To realize that above-mentioned advantage, the technical solution adopted by the present invention and preparation method thereof are as follows:
A kind of aqueous medical belt of antiperspirant and preparation method thereof, it is characterised in that substrate layer uses the blended base fabric of polyester-cotton blend
Layer, the base fabric is laminated to do water-base resin coating bottoming, and the improved water-based glue of antiperspirant is coated on prime coat layer
Pressure-sensitive adhesive layer dries and covers release layer.
Substrate layer of the present invention uses the blended base cloth layer of polyester-cotton blend, is that the close polyester-cotton blend of knitting of plain weave is blended, is less than containing the amount of washing
60%, it is adapted to clinical adhesive tape tearing on the basis of some strength and divides demand and takes into account certain air permeability.
Substrate layer bottoming of the present invention is water-based acrylic resin coating or waterborne polyurethane resin coating.
Antiperspirant of the present invention improves glue pressure-sensitive adhesive layer formula are as follows: 65-85 parts of water-based glue, silane coupling agent 1-
3 parts, 0.5-2 parts of PH regulator, 15-30 parts of antiperspirant, 0.3-1 parts of levelling agent.
