Property, fastness are good.
Realize the technical scheme is that the preparation method of a kind of Viscose glue product, it is characterised in that include
Following steps:
1) by basement membrane coiled material and protective layer coiled material upper volume respectively；
2) being cast straight to adhesive be previously heated in the patterned roll of 70-230 DEG C, adhesive starts solidification,
The ridge design utilizing patterned roll directly makes viscose glue oxidant layer form hole or groove；
3) by high temperature patterned roll, viscose glue oxidant layer and base membrane layer are pressed together；Pressing through high temperature patterned roll
After, adhesive is at least up to semi-cured state；
4) protective mulch compresses, rolling finished product.
Described step 3) complete after, for the solidification of anti-adhesive not exclusively, can be by above-mentioned laminating base membrane layer and viscous
Glue agent layer, then the curing reaction of adhesive is completed by the high temperature oven that temperature is 70-150 DEG C.
Described step 3) in, control height and the patterned roll pressure size to base membrane layer of patterned roll temperature, make
Patterned roll is not pressed and is worn base membrane layer, or makes decorative pattern roll-in wear base membrane layer；When base membrane layer is worn in decorative pattern roll-in, at basement membrane
Form hole or groove on layer, and the hole of base membrane layer or groove corresponding with the hole of viscose glue oxidant layer or groove.
Described basement membrane coiled material is polyurethane film, polyamide membrane, polyethylene film, non-woven fabrics, fabric, foam volume
One of material
Described adhesive is one of polyacrylic acid pressure sensitive adhesive, soft silicone gel, polyurethane gle, PUR.
A kind of Viscose glue product made in aforementioned manners, including protective layer, base membrane layer, viscose glue oxidant layer；Wherein
Base membrane layer is plane sequential like, and viscose glue oxidant layer is grid sequential like, grid protocol regular shape or irregular
Half logical hole or groove of shape；
Described base membrane layer and viscose glue oxidant layer are all in grid sequential like, and the grid of base membrane layer and the net of viscose glue oxidant layer
Lattice are corresponding, these grid protocol regular shapes or erose through hole or groove.
The invention has the beneficial effects as follows:
1, the production technology of wound dressing of the present invention is to utilize the direct pore-forming of high temperature patterned roll or groove, one
The molding of secondary property, efficiency is high, advantage of lower cost
2, obtained Viscose glue product not only ventilative, liquid permeability is good, its intensity also viscous than secondary pore-forming or groove
Glue goods are high.
