Description
Technical field
The present invention relates to a kind of disposable surgical hole towel films and preparation method thereof.
Background technique
Surgical operation towel is just used exclusively for doing the surgical paper of surgical operation, the band on the surgical paper to patient's privileged site
Promising particular procedure position and the hole opened up, surgical operation teacher can perform the operation at the hole position that this presets.
The surgical operation towel of early stage is mainly made of cotton or PE film, due to the limit of the physical property of cotton or PE film itself
System is merely able to realize simple paving Dan Eryi.But the complexity of modern surgery operation requires surgical operation towel according to different function
It can need that a variety of materials is cooperated to go using traditional textile has been difficult to adapt to modern surgical operation.
Summary of the invention
A kind of the object of the present invention is to provide production costs low, elastic and comfort is good and barrier property is excellent disposable hand
Art hole towel film and preparation method thereof.
The present invention adopts the following technical scheme:
A kind of disposable surgical hole towel film comprising A material and B material obtain after being plasticized co-extrusion；
The A material includes the component of following parts by weight: 100 parts of metallocene PE resin and blue 0 ~ 5 part of master batch；
The B material includes the component of following parts by weight: 40-60 parts of SEBS resin, 60-40 parts of POE elastic resin and blue masterbatch
1 ~ 5 part of grain.
Further, the A material includes the component of following parts by weight: 100 parts of metallocene PE resin and blue master batch
4 parts；
The B material includes the component of following parts by weight: 50 parts of SEBS resin, 50 parts of POE elastic resin and blue 4 parts of master batch.
A kind of preparation method of above-mentioned disposable surgical hole towel film comprising following steps:
(1) blender is added in load weighted SEBS resin, POE elastic resin and blue master batch, stirs 3 ~ 8 minutes, takes out
It is spare to expect for B；Metallocene PE resin and blue master batch are weighed as A material；
(2) A is expected that A screw machine extrusion plasticizing is added, B screw extruder extrusion plasticizing is added in B material, and the allocated device enters T simultaneously
Pattern head squeezes out, and forms sheet material；
(3) sheet material obtained in step (2) is formed by knurling steel roll and rubber roll press, is passed through cooling in steel rider and rubber roller
Water, cooling and shaping film forming.
In preparation method, mixing time described in step (1) is 5 minutes.
In preparation method, A screw extruder described in the step (2) is equipped with 5 heating zones, and temperature is respectively as follows: 180
DEG C, 200 DEG C, 210 DEG C, 230 DEG C and 240 DEG C.
In preparation method, B screw extruder described in the step (2) is equipped with 6 heating zones, and temperature is respectively as follows: 180
DEG C, 190 DEG C, 200 DEG C, 210 DEG C, 230 DEG C and 240 DEG C.
In preparation method, the A material and B expect the allocated device distribution, structure are expected using A material/B material/A, with (mass ratio) A material
: B material: A material=1: 1: 1 enters T-die and squeezes out.
In preparation method, the T-die is equipped with 11 heating zones, and each area's temperature is 240 DEG C.
The beneficial effects of the present invention are: it is solved using A/B/A structure in forming press-roller, glue is too viscous and is sticked to rubber roller
Or in flower roll, continuously cannot normally it produce.Solve the problems, such as that simple SEBS raw material is unable to sticking two-faced adhesive tape simultaneously.SEBS resin
POE raw material is added, solves SEBS poor fluidity, phenomenon in uneven thickness.POE resin price is low, same with SEBS resin
When be added relatively be used alone SEBS resin reduce costs, improve economic benefit.
