At present, the high-end playing cards on the market are mainly black-core playing cards, which have the advantage of being opaque and not easy to cheat. At present, the base paper of this kind of playing cards is mainly composed of two single-sided coated papers glued with carbon black and glue. The processing technology is complicated, the loss is large, the cost is high, the output is small, and it mainly depends on imports

Embodiment 1
[0016] Embodiment one: a kind of processing method of black core playing card paper, its concrete processing process is as follows:
[0017] (1), prepare the corresponding surface layer 1, surface layer 2, core layer 3, bottom layer 4 and bottom layer 5 through disintegration, screening, purification, flotation, heat dispersion, bleaching and refining treatment Wood pulp, deinked pulp, waste paper pulp, deinked pulp, and wood pulp;
[0018] (2), in the mixing tank of core layer 3 waste paper pulp, add the black basic dyestuff of relative waste paper pulp absolute dry pulp 5%, add the aluminum sulfate of relative waste paper pulp absolute dry pulp 6% in this mixing tank simultaneously and Fully stir for more than 10 minutes, so that the pH value of the mixing tank is 6.7;
[0019] (3), prepare the coating required for the top coating layer 10 and the bottom coating layer 50 by dissolving, blending, reacting and filtering;
[0020] (4), the slurry that is used to prepare each ...

Abstract
The invention discloses a processing method of black-core playing card paper, which is characterized in that in the pulping process of base paper, black dyes are added in core pulp, and simultaneously trivalent aluminate is added simultaneously and stirred uniformly. The processing method has the advantage of improving affinity of the black dyes and wood fiber in the core pulp due to adding the black dyes and the trivalent aluminate into the core pulp simultaneously, leading the black dyes in the core pulp not to flow into water in the process of paper making and forming of a paper machine, avoiding a wite section of the paper machine from being polluted and ensuring that only the core layer in the processed playing card paper is black. In addition, the method has simple processing, is suitable for large-batch production and has lower production cost.
Description
technical field [0001] The invention relates to a processing method of cardboard in the papermaking industry, in particular to a processing method of black core poker paper. Background technique [0002] As a tool for cultural entertainment, playing cards are widely liked by people. With the improvement of people's living standards, the sales of playing cards are constantly increasing, and the quality requirements of playing cards are also constantly improving. At present, the high-end playing cards on the market are mainly black-core playing cards, which have the advantage of being opaque and not easy to cheat. At present, the base paper of this kind of playing cards is mainly composed of two single-sided coated papers glued with carbon black and glue. The processing technology is complicated, the loss is large, the cost is high, the output is small, and it mainly depends on imports. Contents of the invention [0003] The technical problem to be solved by the present inv...
