Abstract
The present invention relates to an embossed wall paper having a superior 3-dimensional appearance and its preparation, wherein 2 or more kinds of post-printing processes selected from the group consisting of wiping, valley, and top printing can be used in combination, and thus embossed patterns can be delicately expressed and printing can be conducted over a large area. The wall paper of the present invention has superior durability and a 3-dimensional appearance, thus is useful for an interior decoration material for hotels, condominiums, offices, commercial buildings, etc.
Description
Technical field
The present invention relates to a kind of embossing style and have embossing wallpaper of good three-dimensional appearance and preparation method thereof owing to its exquisite performance.More particularly, the present invention relates to a kind of embossing wallpaper and preparation method thereof, this embossing wallpaper thereby can be used as the interior material of hotel, apartment, office, commercial building etc. with good durability and three-dimensional appearance.
Background technology
According to its material, wallpaper that wallpaper can be divided into wallpaper made of paper, made by the vinyl wallpaper of making in conjunction with wallpaper, polyvinyl chloride that constitutes in conjunction with the scraps of paper more than 2 or 2, wallpaper that fiber is made and natural materials etc.; According to its structure, further be categorized as flat wallpaper and embossing wallpaper.A kind of embossing wallpaper prepares by the method that comprises embossing process, and wherein the pattern of concavo-convex engraving is provided on the surface of wallpaper so that the maximization of the sense of reality of product.
A kind of traditional preparation process method of embossing wallpaper comprises step: a), for example use printing methods such as intaglio plate stamp, a gentle version stamp, roller printing, pigment printing on the plane on the surface that will become product printed patterns with the preparation semi-finished product; B) semi-finished product are through heating simultaneously with application pressure between relief roller (embo roll) and the relative backing roll (buck-up roll), thereby formation is as the pattern of relief pattern form; (c) cooling.
The open No.1991-3890 of Korean Patent discloses a kind of preparation and has had the printing of accurate correspondence and the technology of embossed portion, this method is passed through combination by the facing paper of gravure printing apparatus and the protruding seal of emebosser and the auxiliary paper of being introduced by bond roll, so that the corresponding embossed portion of Printing Department, thereby between embossed portion and auxiliary paper, form the space.But according to this common embossing process, all printing process were finished on the plane of product before carrying out embossing process, so printed patterns only is provided on the plane on the final protruding and recessed surface that comprises embossed pattern, can not show three-dimensional appearance fully.
In order to solve the problem in planographic and the embossing process, in order to extrude exquisiter embossed pattern, developed synchronous embossing method, it is a printed patterns and make printed patterns corresponding to the embossed pattern with convex-concave portion that obtains from steel relief roller surface, to show three-dimensional appearance slightly on the product surface of plane wallpaper.For instance, Japan Patent discloses the synthetic resin foam wallpaper that flat 61-70100 discloses a kind of synchronous printing.But this method has also only provided the pattern effect of printing in the plane, and therefore figure (for example, the pattern of flower, setting pattern) performance is not enough, and the three-dimensional appearance performance is restricted.
Therefore, traditional technology is handled because they comprise preparation half product, print and carry out embossing owing to be that planographic has the problem that the three-dimensional appearance performance is restricted.
In order to address the above problem, the back printing treatment is carried out in suggestion, for example wiping printing (wipingprinting), bottom of trench printing (valley printing) and top printing (top printing).But because operating condition, these processing can not be used in combination, and therefore printing can only be carried out at every turn among a small circle.
Japan publication No.06-39984 discloses a kind of by using polyvinyl chloride colloidal sol to form pattern on PVC sheets and removing the method that the barrier paper with convexconcave part is transcribed convex-concave pattern.This method adopts the bottom of trench printing to print on concave portion.But, because wallpaper is by making the semi-finished product of PVC collosol and gel preparation, basic unit's (a kind of base material: non-woven fibre, simile paper (simili) etc.) that need have the ability of the tension force that applies in the processing procedure of being supported on, and because contraction repeatedly and expansion that continuous heating and cooling cause make that this process is impossible substantially.In addition, only can obtain that area is little, width is narrow, ropy type product, and the application of back printing will make productive rate and commercial value in the practical operation reduce.
Japan publication No.08-218298 discloses a kind of method, and this method provides local floral designs such as line and flower by back printing process such as intaglio printing, flexographic printing or roll printing after forming the burr decorative pattern.But above-mentioned patent has been enumerated printing plane process of semi-finished simply.
Simultaneously, according to common wiping method, colored polyvinyl chloride colloidal sol or China ink are a little excessively introduced the convexconcave part of embossing style, use the cutter wiping then, if the height difference of convexconcave part is big, product quality can be unstable.In addition, if embossing style complexity, it is very difficult using cutter.
In addition, traditional bottom of trench typographical display goes out bending (phenomenon that produces the difference of amount of ink transferred around influencing relief roller and transfer printing squeegee of anti-application roll), because the concave portion of embossed pattern is printed simultaneously with embossing, so color is deepened in the middle of final products.Therefore, if carry out large-area printing, product quality is abnormal, therefore can only be applied to small size.
In addition, wherein a kind of of traditional intaglio printing, top method of printing shows level (change gradually of black concentration) on plane surface, if and print at the convex portion of embossing style with big height difference, the expression of printing is restricted so that can only show the part figure.In addition, because the tension difference from convex portion one side to opposite side makes traditional roll printing that poor operability be arranged, and because coarse outward appearance performance can not show exquisite printing.In addition, the China ink that is used in the polyvinyl chloride colloidal sol base in the flexographic printing usually needs the high temperature drying condition, so be suitable for rough image expression.
And the said method of prior art is not mentioned the component that China ink is used in the printshop, back particularly.Up to the present, have high boiling organic solvent such as polyvinyl chloride colloidal sol, cyclohexane, toluene, dimethylbenzene etc. mainly as China ink.But, since dry and cooling period these organic solvents need high temperature to heat (170-200 ℃, 10-20 second), the hardness and the definition that are formed on the embossing style in the embossing process have been lost, and in final products remaining organic matter because its harmful smell total volatile organic compound) and harmful (TVOC:.In addition, the alcohol radical China ink that tradition is used causes unsettled product quality, because China ink volatilizees fast black concentration is increased during long-time operation, only allow the printing or the local batch operation of small size because the mesh of G/V roller and F/X roller blocks, and it can not be used for wherein adopting two continuous methods and the stack printing that repeats drying and cooling.
Therefore, needs are a kind of can large-area applications and the method that shows meticulous three-dimensional appearance.
Summary of the invention
