Abstract
The invention relates to a post-printing process for paper printing, particularly a method for forming a coating on the surface of paper after printing. The technical proposal is that the method comprises using a piece of paper with colored patterns as substrate, printing and coating an organic paint containing silicon dioxide powder on the surface of paper. The coating has high transparency and moderate roughness and serves as a sub-gloss surface. The invention has the advantages of easily-accessible raw material, good color fastness of final products, no stripping and fading, application aswriting tool, suitability for dry or wet cleaning, and uniformity of writing effect. The paper is widely used in teaching, business and advertisement with low cost and good convenience.
Description
Technical field
The present invention relates to a kind of post-press finishing technology of printing sheets, especially relate to a kind of a kind of method that paper surface after the printing is coated with again.
Background technology
In the prior art, utilize the mode of coating to change paper surface hardness and coefficient of friction, thereby realize available slate pencil, chalk and blackboard eraser carry out repeatedly erasable purpose, according to the retrieval, Chinese patent ZL01133654.4 (a kind of coated paper) is arranged, it discloses a kind of " organic coating that contains element silicon mineral powder " and has been coated directly onto on the body paper, with the string paper is base material, rather than be base material to print the back paper surface, practice shows, because the colored picture and text at this paper surface are to be printed on the top layer, look takes place easily become, aberration and shedding, and problem such as moisture-proof wiping not.
Summary of the invention
The objective of the invention is to provide a kind of drawing and writing paperboard, and its not only anti-xerotripsis but also moisture-proof are wiped, and available slate pencil, chalk etc. carry out repeatedly erasablely repeatedly, and the picture and text that keep its surface to print can not fade and come off.
Above-mentioned purpose of the present invention mainly is achieved by following technical proposals: get the paper that is printed on colored picture and text and make base material, a kind of organic coating that contains SiO 2 powder on the surface coated after the printing then, its finished product is coated with rete and has higher transparency and moderate roughness, is dull surface.
Silica organic coating of the present invention is the transparent cold coating that does not contain colored pigment, filler.
As preferably, the granularity of SiO 2 powder is between 1000～1500 orders, and the mass ratio of macromolecule filming material is 0.2～0.8: 1 in the addition in organic coating and this coating.
Major technique characteristics of the present invention are:
Be base material normally in the coating process of prior art with the string paper do not printed; after having printed colored picture and text; the surface of paper is in inhomogeneous state; be that the part that distributes on the same plane is that to contain an element silicon powdery paints part be other colored inks; writing effect has notable difference at different positions; the shedding of easily fading of the part writing effect of printed color picture and text; the present invention is that the paper surface with the chromatic colour picture and text after printing is that base material is coated with; not only can make writing effect clear evenly, also play the effect of protection colored printing face.
Prior art adopts the stronger coating of covering power more, the organic coating that for example contains titanium dioxide and silica, can use this type of coating for the base material bottom surface, to embody the superior function of its strong covering power, but for the paper to have printed colored picture and text described in the present invention is base material and inapplicable, because of its strong covering power should not use as the lining of printed matter, the organic coating that contains SiO 2 powder of the present invention is a kind of other coloured face, filler of not containing, the coating that light transmission is stronger, the lining that can be used as the printed matter coating uses.
The SiO 2 powder that uses in the prior art normally granularity between 270～1000 orders, and SiO 2 powder granularity used in the present invention is between 1000～1500, why this difference is arranged, be that the related coating of prior art belongs to a kind of coating bed material because use in nature, this coating surface has suction and oil absorptive function preferably, and the change of its fineness, smoothness and color can be by coating or ink printing mode realize again.And coating involved in the present invention belongs to the cause that is coated with lining, can directly realize the requirement of fineness, smoothness.
Therefore, the present invention have selection extensively, the finished product fixation by force, do not come off, nondiscolouring, be suitable for that the writing implement scope is wide, the xerotripsis wet rubbing can, and characteristics such as writing effect is even can be used for teaching, office, advertising etc., and are applied widely, economical convenient.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1: coated substrate---and the surface is printed with the 120g/m2 wood-free paper of colored picture and text; Coating medium---go the transparent PVC resin to reach 1000 order SiO 2 powders easily, wherein SiO 2 powder is 0.4: 1 with the content ratio of polyvinyl chloride resin, fully is in harmonious proportion to stir to form; Coating---utilize silk screen blade coating mode to carry out, after the coating evenly, normal temperature is promptly curable.
Embodiment 2: coated substrate---and the surface is printed with the 210g/m2 art paper of colored picture and text; Coating medium---ultraviolet solidifiable UV resin solution and granularity is 1500 purpose SiO 2 powders, and wherein SiO 2 powder and the content of UV resin were than 0.5: 1, and the abundant dispersed with stirring that is in harmonious proportion forms; Coating---utilize cylinder coating machine and ultraviolet ray light source apparatus to be coated with, solidify.
Embodiment 3: coated substrate---and the surface is printed with the 300g/m2 white board of colored picture and text, it is 1200 purpose SiO 2 powders that coating medium---water soluble alkyd resin varnish adds granularity, wherein the proportion of resin present of SiO 2 powder and water soluble alkyd resin varnish is 0.3: 1, forms through the abundant dispersed with stirring that is in harmonious proportion; Coating---by roller coat, oven dry.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
Claims (1)
1, is used for slate pencil, powder enamel pen and wiper and carries out repeatedly erasable a kind of drawing and writing paperboard, it is characterized in that the paper surface to be printed with colored picture and text is a base material, on base material, scribble the silica organic coating of layer of transparent; Described silica organic coating is oily molten type or the water-soluble light transmission organic coating that does not contain coloured pigment; The granularity of described SiO 2 powder is between 1000～1500 orders, and the mass ratio of macromolecule filming material is (0.2～0.8) in its addition in organic coating and this coating: 1.
