And preparation method thereof.
Background technology
Current water-transfer printing paper is coated with using the individual layer paper substrate of 130-170g/ ㎡.Because water-transfer printing paper exists
By, it is necessary to have certain deflection, will otherwise cause during use water transfer brush efficiency is low, printing effect is poor even
Cannot use；And it is existing in the technical field of water-transfer printing paper, the paper base material for using generally all is individual layer paper substrate, i.e., be all by
The obtained product of copy paper production, therefore existing water-transfer printing paper product is often existed, and deflection is not enough, size distortion is big, vertical
Transverse direction performance difference is big, it is necessary to further improve the overall performance of water-transfer printing paper the problems such as production cost is high.In order to improve water
The deflection of transfer paper, existing method is usually predominantly solely by increasing the grammes per square metre of paper base material, that is, to increase its thickness, or adjust
Whole coating formula, or the method for reducing the moisture of product, carry out the deflection of water-transfer printing paper, but improve grammes per square metre often band simultaneously
Carry out greatly improving for product preparation cost, this runs in the opposite direction with the demand for constantly requiring reduces cost, and adjust coating formula, drop
The space that low product moisture can be implemented is very limited, and actual effect is not obvious at present.
The content of the invention
It is an object of the invention to propose a kind of deflection it is higher and it is low production cost with multilayer paper base material coating production
Water-transfer printing paper, due to the paper base material by sandwich construction, then base material is separately granted in requirement that can be according to water-transfer printing paper to base material
Each layer of different performance feature, further properties of lifting final products, at the same can also reduce as far as possible raw material into
This, brings bigger room for improvement.
It is another object of the present invention to propose a kind of preparation side of the water-transfer printing paper with the coating production of multilayer paper base material
Method, realize disposably with multi-ply paper substrate forming add coating produce, with it is in hgher efficiency, can more flexibly prepare the characteristics of.
It is that, up to this purpose, the present invention uses following technical scheme：

Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of water-transfer printing paper with the coating production of multilayer paper base material, includes back coating successively from the bottom to top
1st, substrate layer 2, priming coat 3, core coating 4 and top coat 5；
The substrate layer 2 is formed by multi-disc l Water Paper page superimposion, is included bottom 21, sandwich layer 22 successively from the bottom to top and is applied
Layer of cloth 23；The lower surface of the bottom 21 fits in the back coating 1, and the upper surface of the coating layer 23 fits in the bottom
Coating 3.
A kind of water-transfer printing paper with the coating production of multilayer paper base material proposed by the present invention, mainly from the structure for changing substrate layer
The problems such as deflection to solve existing water-transfer printing paper is not enough, and is only in the prior art solely to increase the grammes per square metre of base material to increase
Plus the thickness of base material, or adjust coating formula compares with the method for reducing moisture, knot of the application from the substrate layer
Improved on structure, each layer function is clearly more demarcated, i.e., by the production technology of the sandwich construction of the substrate layer 2, be respectively provided with
The hierarchy of the bottom 21, the sandwich layer 22 and the coating layer 23, it is well arranged, can be with wherein between every aspect
Requirement according to water-transfer printing paper to base material, separately grants with different performances, so that the performance of each layer is more stablized, by institute
The performance for stating substrate layer 2 is maximized, so as to increased the integrally-built performance characteristics of the water-transfer printing paper, reduce raw material into
This, brings bigger room for improvement.
Wherein, in order to increase the deflection of the water-transfer printing paper, it is to avoid size distortion is big and directional performance difference is big in length and breadth
Problem, by the setting of the sandwich layer 22, adjusts the paper fiber orientation situation of different aspects in the substrate layer, so as to increase base

23 and bottom 21 cover, the function distribution of the sandwich layer is mainly to provide deflection, dimensional stability, but less demanding to outward appearance
Feature, therefore by allotment individually to the center stock of paper substrate, not only reduces the preparation cost and effectively of the substrate layer 2
Increased the overall deflection of the substrate layer 2, hence it is evident that the big problem of existing individual layer base paper change in size is improved, for example, described
Sandwich layer can be using the mechanical pulp being made up of bamboo pulp and softwood slurry, and it has deflection higher and the relatively low feature of price.
Further illustrate, the coating layer 23 is the l Water Paper page that the de-watering of slurries being made up of broadleaf slurry shapes, described wealthy
The fibre diameter of leaf material slurry is 0.015~0.025mm.The lower section of the priming coat 3, the coating are arranged at due to coating layer 23
The function distribution of layer 23 is mainly coating performance, smoothness and dimensional stability, therefore can be using broadleaf slurry as raw material；It is wealthy
Leaf material slurry is the supplier of preferable page surface characteristic, and broadleaf fiber belongs to fiber fines；And fiber fines help to constitute
Page surface smoothness, can obtain the page of good smoothness；Due to being the paper of layer in the substrate layer 2 of sandwich construction
Layer, even if thus this aspect using more high-quality pulp material, its raising influence on substrate layer totality cost is little, may be used also
To obtain more preferable Painting effect, that is, meet the performance requirement of preferable smoothness and coating adherence, and reduces cost, realize
The maximization of performance.
Further illustrate, the bottom 21 is the l Water Paper that the de-watering of slurries being made up of needle slurry, broad-leaved slurry and bamboo pulp shapes
Page, the injection index of the slurry is 26~32mm/min.The top of the back coating 1, institute are located at due to the bottom 21
Function distribution mainly deflection, water imbibition, the dimensional stability of bottom 21 are stated, therefore is entered using needle slurry, broad-leaved slurry and bamboo pulp
Row compounding, so that the bottom 21 has higher water absorption and deflection performance high；The substrate layer is by being set to multilayer
Structure, its respective design feature and function and usage can be directed to, the characteristics of to be allocated its performance to each layer respectively, make knot
Structure and performance distribution are more reasonable, while also for reduces cost brings more regulation spaces.
A kind of preparation method of water-transfer printing paper with the coating production of multilayer paper base material, comprises the following steps：
(1) it is with slurry：Different paper pulp are carried out into size degradation, and the purifier sieve removal of impurity, different slurries are obtained；
(2) multiple-unit difference copy paper：It is by the different slurries respectively by single-layer headboxes and de- on forming net respectively
Water forms multi-disc l Water Paper page；
(3) multilayer off-grid overlapping：L Water Paper page off-grid described in multi-disc is overlapped, multilayer l Water Paper page is compounded to form；
(4) squeeze, dry：Multilayer l Water Paper page is further dehydrated by mechanical expression, multilayer paper base material is obtained, its
Mass dryness fraction is 48~50%；And dried, the mass dryness fraction for making the multilayer paper base material is 92~95%；
(5) press polish：Press polish is carried out again to the multilayer paper base material after squeezing drying；
