Description
Technical field
The present invention relates to a kind of medical adhesive tapes to belong to medical material skill more particularly to a kind of medical adhesive tape manufacturing process
Art field.
Background technique
The substrate of medical paper self-adhesive tape is mainly terylene short fiber or viscose, also has the paper self-adhesive tape of large scale wood pulp ingredient, greatly
The medical paper self-adhesive tape in part produces base fabric using dry non-woven technique, and this base fabric is soft, good permeability, but its feature
Ultimate strength is inadequate and the back side is almost without off-type force as in adhesive tape class product, then showing as, so needing before gluing
Pretreatment is done to reach gluing requirement.The technique of mainstream is to first pass through to pad base fluid (base fluid is generally adopted by butadiene-styrene rubber at present
Cream or acrylic acid ester emulsion) come complete increase strength requirement, then by substrate backside mould release it is release to reach single side
Effect, finally carry out gluing and subsequent technique, complete after packaging to be exactly a complete product.But after prior art processing
Substrate feel it is partially hard, gas permeability be deteriorated etc., also will cause retraction loss；It is common organic when carrying out release processing substantially
Silicon is although environment friendly and pollution-free, but the unstability due to silicon class product after in conjunction with substrate, will cause production after gluing
Raw serious migration, so that product gluing performance dramatic decrease, causes the stability of product inadequate.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of medical adhesive tape manufacturing process, and substrate is made to be provided simultaneously with increase
Strength and back side generation are release, while reducing the injury to the entire performance of substrate, and the loss of the breadth of substrate reduces, and improve and apply
The viscosity of glue rear substrate.
To achieve the above object, a kind of medical adhesive tape manufacturing process of the present invention, includes the following steps:
(1), substrate is configured；Made of the raw material that substrate is matched following weight, wood pulp 20~40%, polyvinyl 20~
30%, water-soluble fibre 20~40%, composite man-made fibre 10~20%；
(2), the configuration of padding liquid: first configuring base fluid, and by 6 to 10 parts of butadiene-styrene latex, 1 to 3 part of water is mixed to get base fluid, so
10% to 15% emulsifying wax of base fluid total amount and 0.1% to 0.3% crosslinking agent is added in base fluid afterwards, after mixing sufficiently,
Obtain padding liquid；
(3) arrangement of substrate: using the padding liquid in step (2), evenness calender is configured, and by evenness calender to substrate
It carries out padding processing, padding the time is 0.8 to 1.5 second.
Further, the specific preparation flow of substrate is as follows:
1), be beaten using beater: beating consistency 2.5~3.0%, be beaten 50~60A of ampere, 15~20 points of beating time
Clock；
2), in reserve pit, add brightening agent 0.1%, add water-and oil-repellent agent 1.5~2.0%, the swollen time was on 3 hours left sides
It is right；
3) it, uses on machine and is coated with: smears PVA, coating concentration 2~3%；4), make drying and processing, temperature and time with
Oven-dry paper is principle.
2) and 4) further, in optic vesicle foam situation between process, in stock tank plus 10~20ml silicon class defoaming agent.
It further, include water-soluble paraffin and butyronitrile in step (2), in the ingredient of emulsifying wax.
Further, after the arrangement of step (3) substrate, the gain in weight of substrate is controlled 12 to 18gsm.
Compared with prior art, the present invention only through single treatment, can make substrate while reaching had increase strength and
The back side generates release purpose, while reducing the injury to the entire performance of substrate, and the loss of the breadth of substrate reduces；It pads
Afterwards, water-soluble paraffin can effectively fill the gap on substrate, be conducive to subsequent coating technique, improve the glue on substrate unit area
Water, to improve the viscosity of gluing rear substrate；After being handled by long mesh paper making machine, the vertically and horizontally distribution of fiber is relatively uniform, knot
For structure than more loose, air permeability is higher than the product that other formers are manufactured paper with pulp；Due to using longer synthetic fibers, so that product
Intensity is also improved.
