Abstract

The utility model provides a mirror surface white board. The white board comprises a white board body and a mirror surface layer formed on the surface of the white board body, wherein the mirror surface layer is a water-based direct coating transfer layer or an assembly of a water-based transfer bonded coating layer, a water-based bridging coating layer and a release layer which are compounded on the surface of the white board body from inside to outside in sequence. The mirror surface white board has a bright and flat surface, is high in flexibility, elasticity and inking property, and can adapt to various printing modes, powder does not fall off the white board, and a finished product is high in flatness after the white board is printed.

Description

A kind of minute surface white duplex board

Technical field

The utility model relates to the cigarette wrapping paper field, specifically a kind of minute surface white duplex board.

Background technology

Cigarette package mainly use white duplex board or with white duplex board as the various gold and silver paperboards of base stock, radium-shine paperboard, high light tipping paper, with regard to the feature of environmental protection, obviously white duplex board is environmental protection the most; Common white duplex board is because its printing surface uses is the scraper coating of twice or three times; Do not do further processing, when printing,, cling coating easily and also pull up on paper because the printing ink stickiness of using is bigger; Can cause dry linting to fall a mao phenomenon; Make and grow dim on the printed matter image, thereby influenced print quality, also can cause printed matter to be scrapped when serious.

The utility model content

The technical problem that the utility model will solve is, to the shortcoming that traditional cigarette packing white duplex board exists, provides that a kind of brightness is high, suppleness and good springiness, inking property are good, dry linting not, can adapt to the high-quality cigarette package white duplex board of multiple mode of printing.

In order to solve the problems of the technologies described above.The utility model adopts following technical scheme: a kind of minute surface white duplex board; Comprise a white duplex board and a specular layer that forms on the white duplex board surface, said specular layer is that water-based directly is coated with transfer layer or shifts the assembly that combines dope layer, water-based bridge formation dope layer and release layer by the water-based that is compounded in the white duplex board surface successively from inside to outside.

Further, in above-mentioned minute surface white duplex board, the thickness that said water-based directly is coated with transfer layer is 3～4 microns.

Further, in above-mentioned minute surface white duplex board, the thickness that said water-based shifts the combination dope layer is 2.5～3.5 microns.

Further, in above-mentioned minute surface white duplex board, the thickness of said water-based bridge formation dope layer is 1.2～2 microns.

The utility model beneficial effect is following: through changing the structure of common white duplex board; Increase one deck or which floor transparent pliable and tough nonpoisonous and tasteless aqueous, environmental protective coating at paper surface; Make it have higher glossiness and smoothness, suppleness, have good, the advantage such as dry linting not of good springiness, inking property, can adapt to multiple mode of printing than common white duplex board; After finishing printing finished product, has good calm property, to guarantee normally use on cigarette packer.

The specific embodiment

The utility model provides a kind of minute surface white duplex board, comprises a white duplex board 1 and a specular layer that forms on the white duplex board surface.Totally two kinds of embodiments.

Embodiment 1:

With reference to figure 1; This specular layer combines dope layer 2, water-based bridge formation dope layer 3 and release layer 4 to form for being shifted by the water-based that is compounded in the white duplex board surface successively from inside to outside; The main component that water-based shifts combination dope layer 2 is acrylic resin modified, and the main component of water-based bridge formation dope layer 3 is acrylic resin modified and cellulose.

The preparation method of present embodiment is the dry film transfer method, and its step is following:

1) coating one release layer 4 on the PET basement membrane, thickness is 2～3 microns;

2) coating one deck water-based bridge formation dope layer 3 on the PET of coated release layer 4 film; Make water-based shift combine to combine between dope layer 2 and the release layer 4 firm; And avoid water-based to shift and combine dope layer 2 molecular migrations to be penetrated into release layer 4 surfaces; Thereby influence the printability of paper surface, thickness is 1.2～2 microns;

3) go on foot coating one water-based transfer combination dope layer 2 on the PET film that obtains through the 2nd then; This coating layer has higher solid content; Can the slight void of paper surface be filled up; Thereby increased the flatness and the brightness of paper, cohesive force makes paper surface combine more firmly with water-based bridge formation coating 2 and release layer 4 preferably simultaneously, and it is 2.5～3.5 microns that water-based shifts combination dope layer 2;

4) carry out compoundly with white duplex board again, after oven drying, the PET basement membrane is peeled off.

Embodiment 2:

See Fig. 2, the surface of white duplex board 1 forms a specular layer, and this specular layer is that a water-based directly is coated with transfer layer 5; This coating is main body with the modified acroleic acid, with the milky white liquid of water as diluent, and solid content about 45%; High solid content adds certain thickness; Make paper surface smooth more smooth, the surface is bright especially, just as minute surface.

Preparation method among the embodiment 2 is the wet film transfer method; The steps include: that the coating water-based directly is coated with transfer layer 5 on PET basement membrane or OPP basement membrane; Thickness is 3～4 microns; And carry out compoundly with white duplex board, and after oven drying, PET basement membrane or OPP basement membrane to be peeled off, the oven drying temperature is 80 ℃～100 ℃.

Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be with accompanying claims.

Claims (4)

1. minute surface white duplex board; Comprise a white duplex board and a specular layer that forms on the white duplex board surface, it is characterized in that: said specular layer is that water-based directly is coated with transfer layer or shifts the assembly that combines dope layer, water-based bridge formation dope layer and release layer by the water-based that is compounded in the white duplex board surface successively from inside to outside.

2. minute surface white duplex board according to claim 1 is characterized in that: the thickness that said water-based directly is coated with transfer layer is 3～4 microns.

3. minute surface white duplex board according to claim 1 is characterized in that: the thickness that said water-based shifts the combination dope layer is 2.5～3.5 microns.

4. minute surface white duplex board according to claim 1 is characterized in that: the thickness of said water-based bridge formation dope layer is 1.2～2 microns.
