Drawings
FIG. 1 is a schematic structural diagram of the present invention
FIG. 2 is a process flow diagram of the present invention.
Detailed Description
Embodiments of the present disclosure are described below with reference to the accompanying drawings: as shown in fig. 1, the anti-counterfeit coated ivory board of the present invention is formed by combining a surface paper layer and a pattern layer, and comprises a surface paper layer 1, a base paper layer 2, a core paper layer 3, two pattern layers 4, a coating layer 5, and a starch layer 6 (which may also be a coating layer), wherein the pattern layer 4 is arranged between the surface paper layer 1 and the core paper layer 3, and between the base paper layer 2 and the core paper layer 3; the anti-counterfeiting coated white cardboard of the invention can have two or three core paper layers 3 and three or four pattern layers 4.
Example 1
1. Pulping
Firstly, a surface paper layer: pulping the pulp sheet of the surface paper layer by a hydrapulper, pulping (directly pulping if self-pulping), blending, and making into pulp by a paper feeder.
Bottom paper layer: pulping the pulp board of the bottom paper layer by a hydrapulper, pulping (directly pulping if self-pulping), blending, and making into pulp by a paper feeder.
2. Addition of Pattern
The personalized anti-counterfeiting pattern is sprayed between the surface layer and the bottom layer through a unique flow system of the paper machine net part in a spraying mode.
3. Papermaking
The surface paper pulp and the bottom paper pulp which are made by papermaking are respectively sent to a surface net and a bottom net of a paper machine for papermaking, and then the paper is formed by pressing, drying, coating and final calendaring and finishing.
Secondly, in the finished product made by the paper, the patterns in the paper can be seen in the bottom paper layer in a concealed way, and complete and clear patterns can be seen clearly when the paper layer is torn.
4. White water system
In the paper making process of the paper machine, white water of the surface paper layer and the bottom paper layer is separated, two special white water tanks (pools) of the surface paper layer and the bottom paper layer are arranged, and the white water of each layer is separately used when pulp is diluted on the paper machine and pulp boards are disintegrated and concentrated in a pulping section.
Example 2
The anti-counterfeiting coated white cardboard consists of a surface paper layer, a core paper layer and a bottom paper layer, and the production method comprises the following steps:
1. pulping
Firstly, a surface paper layer: pulping the pulp sheet of the surface paper layer by a hydrapulper, pulping (directly pulping if self-pulping), blending, and making into pulp by a paper feeder.
② core paper layer: the pulp board of the core paper layer is disintegrated by a hydrapulper and then is defibered or pulped (if the pulp board is self-made, the pulp board is directly defibered or pulped), then the material is proportioned, and the manufactured pulp paper feeder is used for paper making.
③ base paper layer: pulping the pulp board of the bottom paper layer by a hydrapulper, pulping (directly pulping if self-pulping), blending, and making into pulp by a paper feeder.
2. Incorporation of patterns
The personalized anti-counterfeiting pattern is sprayed among the surface, the core and the bottom layer in a spraying mode through a unique flow system of the paper machine net part, and one or more layers of same or different patterns can be sprayed according to the requirement. And controlling the running speed of the paper machine, and intermittently or continuously spraying by adopting preset spraying equipment in a spraying mode to realize the stable reappearance of the pattern.
The spraying equipment coordinates the speed of the paper machine, so that a pattern layer with uniform space and pattern is formed.
3. Papermaking
The prepared pulp of each layer is respectively sent to a surface net, a core net and a bottom net for papermaking, then the fuzzy anti-counterfeiting pattern can be seen in the finished product after squeezing, drying, coating and calendaring finishing, and the complete and clear pattern can be clearly seen when the paper layer is torn.
4. White water system
The paper machine white water of the surface paper layer, the core paper layer and the bottom paper layer is separated, and a special white water storage tank (pool) is arranged. The diluted white water in the approach section of the paper machine is used separately, and the white water used for pulping and thickening in the pulp making section is also used separately to prevent the white water in each layer from mixing.
Example 3
The process conditions were the same as in example 2, and after the sheet was formed, a layer of pattern was sprayed onto the back of the sheet, with the spray point being selected both before and after the back coating.
