Description
Technical field
The present invention relates to a kind of bandage, specifically a kind of four sides elasticity bandage.
Background technique
Bandage is widely used in the medical fields such as operation, wound dressing as a kind of medical dressing, while daily
Also there is more application in nursing, movement protection, has primarily served support, protection, orthopedic and other specific functions.It is existing
Bandage is roughly divided into two kinds: one is the bandage for having glue without any elastic force, such as athletic tape hangs salt water use
Papery Non-woven tape, this bandage do not have any elasticity, because variation synchronous with body deformation cannot be achieved, when use
Comfort it is inadequate；Another kind for through to elastic and broadwise does not have elastic force and has the bandage of glue, such as self-adhesion is taut
Band etc..Existing Elastic bandage majority be through to elastic and broadwise do not have elastic force, after being attached to skin surface, bandage
Always in a state of stress, with the extension of use time, edge will appear the phenomenon that warps, and especially be attached to elbow joint, when
When elbow is bent, bandage is easy to collapse out, to leave coating surface, leverages the comfort and persistently of patient
Property.
Summary of the invention
The purpose of the present invention is to provide a kind of four sides elasticity bandages, have good elasticity, can stretch to four sides, by
Power is uniform, and tension is also more stable, effectively prevents warping phenomenon and collapses out phenomenon.
To achieve the above object, the invention provides the following technical scheme:

Raw material according to mass percent includes EVA resin 50-80%, tackifier 10-30%, viscosity modifier 5-20% and antioxidant 5-
10%。
As a further solution of the present invention: the elongation at break of the polyurethane spandex thread is up to 500%, releases external force
After can recover immediately former length.
As a further solution of the present invention: the tackifier are rosin and its derivative, terpene resin and its modifier
One or more of.
As a further solution of the present invention: the viscosity modifier is one of paraffin and microwax.
As a further solution of the present invention: the antioxidant be phosphite ester, antioxidant 264, N, N- DPD di p phenylenediamine,
Dibutyl two dredges the mixture for one or more of carbaminate and 2,6 di-t-butyl methylphenols.
The preparation process of the four sides elasticity bandage, comprising the following steps:
(1) preparation of environment-friendly type plasticity adhesive, comprising the following steps:
11) EVA resin is weighed, using heating water bath to 95-100 DEG C, is heated while stirring, until EVA resin melts；
12) tackifier, viscosity modifier and antioxidant are then sequentially added in proportion, stir 30-40min；
13) again by strainer filtering, filtered liquid is environment-friendly type plasticity adhesive；
(2) ready environment-friendly type plasticity adhesive, four sides elasticity cloth and polypropylene film are respectively pivoted to glue-smelting machine
Glue case and corresponding roll shaft on, in the case where glue box temperature degree is set as 100-140 DEG C, to glue case heat, in glue case
After environment-friendly type plasticity adhesive melts, environment-friendly type plasticity adhesive is coated on polypropylene film by the roll shaft of gluing
Face, then the environment-friendly type plasticity adhesive above polypropylene film is transferred to above four sides elasticity cloth by transfer roll shaft；
(3) glue-coated four sides elasticity cloth passes through splitting winding, forms four sides elasticity bandage.
Compared with prior art, it the beneficial effects of the present invention are: the present invention has good elasticity, can be drawn to four sides
It stretches, uniform force, tension is also more stable, effectively prevents warping phenomenon and collapses out phenomenon.The present invention has splendid comfortable
Property and gas permeability, while texture it is soft, convenient for being fastened, after being bonded with human skin, the activity of human body is adapted to, with stretching
It is brisk comfortable with contracting, it is more convenient when wrapping up use.
