Abstract
The utility model relates to a single-sided back treatment dust-free paper for preparing medical adhesive tapes and an adhesive tape prepared from the single-sided back treatment dust-free paper. A resin layer is quantitatively coated on one surface of a backing material layer to substantially form a film thereon, and a small quantity of resin permeates into the other surface of the backing material layer, so that when coating a glue layer in the subsequent step, the glue layer does not permeate to the backing material layer; and the resin layer is quantitatively coated with a silicone oil layer. The single-sided back treatment dust-free paper can be used for preparing medical adhesive tapes, and has the advantages of simple preparation process, stable product quality and low cost.
Description
Technical field
The utility model relates to a kind of single face back of the body of making medical adhesive tape and handles dust-free paper, belongs to dust-free paper and makes the field.
Background technology
CN101484639A, title " a kind of dust-free paper and manufacturing technique thereof " with fluid absorbent, 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.
Design: in order to realize above-mentioned purpose of design.The designed single face of the utility model back of the body is handled dust-free paper, is by resinizing on base material, is coated with silicone oil again and makes.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.
The utility model key technology 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.
Technical scheme: 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.
The utility model is compared 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.
Description of drawings
Fig. 1 is the structural representation that the single face back of the body is handled dust-free paper.
Fig. 2 is resin-coated structural representation.
Fig. 3 is the structural representation that silicone oil is coated with three rollers.
Fig. 4 is the structural representation that silicone oil is coated with five rollers.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～4.The single face back of the body is handled dust-free paper, and base material 3 one sides scribble resin bed 2, scribble one deck silicon layer 1 on the resin bed 2.Described base material 3 is meant nonwoven fabric, cloth, yarn.Its single face back of the body is handled the preparation method of dust-free paper: by closed loop tension system control nonwoven dry goods base material tension, reach no tension coating, deflection is controlled in 6%.At quantitatively resinize layer 2 and in the basic film forming of the one side of substrate layer 3 and have the another side that low amounts of resin 2 is penetrated into base material 3 of the one side of substrate layer 3, force in follow-up gluing water layer, glue layer can not permeate substrate layer 3, resin bed 2 quantitatively scribbles silicon layer 1, the coating weight of its silicon layer 1 is no more than the critical point of resin penetration, in order to reach this point, adopt anilox roll quantitatively to be coated with silicone oil.Its coating method: (1) selectes anilox roll, adjusts the speed ratio between rubber rollers, the anilox roll, can control 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, by closed loop tension system control tension, reaches no tension coating, and deflection is controlled in 6%.
The 4th, pressure roller; The 5th, even cloth rewinder roll; The 6th, anilox roll; The 7th, resin solution; The 8th, scraper; The 9th, base material; The 10th, squeegee.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; it is simple description to the utility model mentality of designing; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection model of the present utility model.
Claims (2)
1. a single face back of the body is handled dust-free paper, and it is characterized in that: base material simultaneously scribbles resin bed, scribbles one deck silicon layer on the resin bed.
2. the single face back of the body according to claim 1 is handled dust-free paper, and it is characterized in that: described base material is meant nonwoven fabric, cloth, yarn.
