Embodiment 1

[0043] The manufacturing process of the present invention comprises the following processes:

[0044] (1) Production of mixed white material: DC dispersant 0.21%, sodium hexametaphosphate 0.13%, caustic soda 0.09%, antifoaming agent 0.21%, kaolin 64.47%, CMC-50: 0.52%, the rest is water, put in high speed In the dispersion tank, stir for 3-4 hours, and then go through the high-speed colloid back and forth rubber mill 10 times, and store it for later use. The quality parameters of the mixed white material are as follows, solid content: 42%; viscosity: 110MPS; pH value: 6.3.

[0045] (2) latex boiling:

[0046] A. Polyvinyl alcohol spare solution:

[0047] First add water into the reaction pot, and when the water temperature reaches 60°C, add polyvinyl alcohol so that the polyvinyl alcohol content is 8% (g / g), stir while heating in the reaction pot, the temperature reaches 100°C, Until the polyvinyl alcohol is completely dissolved, keep warm for standby (the temperature is con...

Embodiment 2-6

[0067] In the production process of the present invention, the black core slurry is made and put in raw material quantity (mass percentage) and sequence, and the temperature of preparing polyvinyl alcohol solution is as follows:

[0068]

[0069] Other process operation steps are as embodiment 1.

Abstract

The production process of black core card paper includes the following steps: compounding black core pulp, painting black core pulp with air knife onto chrome paper, stoving to form black core paper, combining two sheet of black core paper via black side to black side, burnishing and cutting into the black core card paper. The black core pulp is compounded with PVA, phosphate starch and polyether. The black core card paper is used to produce playing card with the patterns on both sides incapable of being seen from the other side, smoothness, good hand feeling and even high elasticity.

Description

1. Technical field [0001] The invention relates to a manufacturing process of black-core cardboard, in particular to black-core cardboard for making playing cards. 2. Background technology [0002] At present, the paper used for high-end poker cards in the international and domestic markets basically uses black paper on the inner core and coated paper coated with white on both sides. Patterned perspective. However, there is no domestic manufacturer that produces black core cardboard by itself. If it needs to be used, it is imported from abroad. However, the process of producing black core cardboard abroad is relatively complicated and the cost is relatively high. Therefore, imported black core cardboard is used. Paper makes the cost of playing cards significantly increased, and for consumers, the cost is relatively high. 3. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing process of black core pa...
