Problems solved by technology

[0003] Both playing card board and playing cards require a certain number of folding endurance, longitudinal stiffness and elastic properties, but most of the playing cards currently on the market cannot meet the requirements, and there is still a certain gap between them and high-end playing cards
When the playing card board paper machine is used for multi-net forming papermaking, in order to reduce the delamination of the cardboard, the interlayer spray adhesive is used to increase the adhesion between the layers, but the concentration of the starch adhesive for spraying is low, increasing The amount of dehydration in the net part is reduced, and the felt and net are easily polluted

Embodiment 1

[0021] A kind of playing card cardboard, comprises face layer, face liner layer, core layer, bottom liner layer and bottom layer arranged in sequence, such as figure 1 As shown, the core layer is composed of a fiber layer 1 containing water-soluble fibers and powdered rubber fillers and has holes 2. The holes 2 are evenly distributed to form a spatial network structure. The holes 2 have irregular shapes. The holes 2 The total area accounts for 1 / 3 of the total area of ​​the fiber layer 1, and the area of ​​each hole 2 is 4mm 2 . The content of the water-soluble fiber is 15% of the weight of the core layer. The amount of the powdered rubber filler is 8% of the weight of the core layer.

[0022] Its production method is as follows:

[0023] (1) Prepare wood pulp, deinked pulp, deinked pulp and wood pulp;

[0024] (2) Add 15% water-soluble fiber (polyvinyl alcohol fiber, fiber length 3mm, The dissolution temperature is 60°C, Shenzhen Huasu Technology Development Co., Ltd.),...

Abstract

The invention provides a playing card paperboard, comprising a surface layer, a surface lining layer, a core layer, a bottom lining layer and a bottom layer, which are sequentially arranged. The playing card paperboard is characterized in that the core layer is formed by a fiber layer comprising water-soluble fibers and powered rubber filler and having holes, wherein the holes are uniformly distributed to form a spatial net structure and have irregular shapes; the total area of the holes is 1 / 3 to 3 / 4 of the fiber layer total area; and the area of each hole is not lager than 16 mm<2>. The adhesive spraying process among the core layer, the surface lining layer and the bottom lining layer is reduced; the interlayer bonding force between the core layer and the paper pages on the two sides can be increased; the tensile strength, the deflection and the folding strength of the core layer and the playing card paperboard are greatly improved; the use amount of the core layer fibers is reduced; meanwhile, the elasticity and hand feeling of the playing card paperboard are enhanced; and the adoption of the colorful powered rubber filler can increase the optical opacity of the playing card paperboard.

Description

technical field [0001] The invention relates to a playing card cardboard and a production method thereof, belonging to the technical field of papermaking. Background technique [0002] Poker is a game that does not divide age groups and has few restrictions. With the continuous enrichment and growth of entertainment life, the demand for playing cards in the market has increased rapidly. According to statistics, as of 2010, China has become the largest producer and consumer of poker dust in the world. [0003] Both playing card board and playing cards require a certain number of folding endurance, longitudinal stiffness and elastic properties, but most of the playing cards currently on the market cannot meet the requirements, and there is still a certain gap between them and high-end playing cards. When the playing card board paper machine is used for multi-net forming papermaking, in order to reduce the delamination of the cardboard, the interlayer spray adhesive is used t...
