Abstract
The invention relates to single-sided back processing dust-free paper for fabricating a medical adhesive tape and an adhesive tape fabricated by the same. A resin layer is coated on one side of a substrate layer quantitatively, one side of the substrate layer forms a film basically, and less resin is permeated into the other side of the substrate layer so as to force a glue water layer not to be permeated into the substrate layer when sequentially coating the glue water layer, a glue water layer is coated on the other side of the substrate layer, and a silicon oil layer is quantitatively coated on the resin layer. The invention enables the fabrication of the single-sided dust-free paper for the medical adhesive tape to be realized and has simple fabrication process, stable product quality and low cost.
Description
Technical field
The present invention relates to a kind of single face back of the body of making medical adhesive tape and handle dust-free paper and handle the adhesive tape that dust-free paper is made, belong to dust-free paper and adhesive tape and make the field with the single face back of the body.
Background technology
CN101484639A, title " a kind of dust-free paper and manufacturing technique thereof " with liquid-absorbent performance; This dust-free paper is formed by the air-laid process manufacturing, and its structure is formed by three layers altogether: ground floor mainly comprises cellulose fibre, bicomponent composite fibre and emulsion; The second layer comprises cellulose fiber peacekeeping water absorbing polymer particle (SAP); The 3rd layer mainly comprises cellulose fibre, bicomponent composite fibre, water absorbing polymer particle (SAP) and emulsion, and the two sides to this dust-free paper product has sprayed emulsion in production technology in addition, in order to the surface finish of dedusting and product.This dust-free paper can be separately or is disposable or with the absorption core of promptly abandoning amenities as women sanitary articles, adult-incontinence articles, baby paper diaper etc. with other dust-free paper or nonwoven fabric combination.Its weak point: can't be used to make medical adhesive tape.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of single face back of the body of making medical adhesive tape that can be used in and handle dust-free paper and handle the adhesive tape that dust-free paper is made with the single face back of the body.
Design: in order to realize above-mentioned purpose of design.Single face that the present invention the designed back of the body is handled dust-free paper, is through on base material, resinizing, and is coated with silicone oil again and processes.Base material: mainly being nonwoven fabric, also can be cloth, cotton yarn and so on.Be commonly called as and be coated with silicon nonwoven fabric, release nonwoven fabric, separation cloth, release yarn etc., be mainly used in and make medical adhesive tape.
Key technology of the present invention is that single face is shaped: 1, quantitatively resinize in the one side of base material, the effect of resin is in the basic film forming of the one side of layer and has and be penetrated into reverse side on a small quantity.In subsequent production gluing water layer, glue layer can not permeated.The coating of resin bed must be quantitative coating, very little, is unfavorable for film forming; Too much, nonwoven fabric can dissolve in resin, and quantitative methods is that anilox roll quantitatively is coated with.2, behind the coated substrate layer, on three rollers or the five roller coat leftover of bolt of cloth, quantitatively be coated with silicon layer, silicon layer is coating quantitatively, does not peel off effect very little; Too many, silicone oil still can pass resin bed, substrate layer, is penetrated into the reverse side of substrate layer, causes glue layer to come unstuck.So the coating weight of silicone oil should not surpass the critical point of infiltration.3, coating method: anilox roll is selected in (1), and the speed ratio between adjustment rubber rollers, the anilox roll can be controlled coating weight.(2) selected anilox roll is regulated the speed ratio between each roller, can control coating weight.Three-roller is the same with the operation principle of five-roller, but the uniformity of five-roller can be better, and quantitative accuracy is also higher.4, because of nonwoven dry goods base material elasticity is bigger, the distortion of coating back is very big, through closed loop tension system control tension, reaches no tension coating, and deflection is controlled in 6%.
Technical scheme 1: the single face back of the body is handled dust-free paper, and base material simultaneously scribbles resin bed, scribbles one deck silicon layer on the resin bed.
Technical scheme 2: the single face back of the body is handled the preparation method of dust-free paper; At quantitatively resinize layer and in the basic film forming of the one side of substrate layer and have the another side that low amounts of resin is penetrated into base material of the one side of substrate layer; Force in follow-up gluing water layer; Glue layer can not permeate substrate layer, and resin bed quantitatively scribbles silicon layer.
Technical scheme 3: adopt the single face back of the body to handle the adhesive tape that dust-free paper is made, base material simultaneously scribbles resin bed, scribbles one deck silicon layer on the resin bed, and the base material another side scribbles glue layer.
Technical scheme 4: adopt the single face back of the body to handle the method that dust-free paper is made adhesive tape; At quantitatively resinize layer and in the basic film forming of the one side of substrate layer and have the another side that low amounts of resin is penetrated into base material of the one side of substrate layer; Force in follow-up gluing water layer; Glue layer can not permeate substrate layer, substrate layer another side gluing water layer, and resin bed quantitatively scribbles silicon layer.
The present invention compares with background technology, and the one, the making of medical adhesive tape single face dust-free paper is achieved; The 2nd, the adhesive tape of made reaches the requirement of the U.S. and European importer; The 3rd, manufacture craft is simple, constant product quality, and cost is low.
