Description

Technical Field

[0001] The utility model relates to the technical field of playing cards, in particular to a waterproof playing card paper containing polysilazane. Background Art

[0002] A waterproof card paper containing polysilazane is mainly used to improve the durability and protective performance of card paper in various environments, so that it can better meet the needs of various card application scenarios such as game cards, collectible cards, and identity cards, and protect the patterns, text and other information on the cards from damage by factors such as water, dirt, high temperature, fatigue and oxidation.

[0003] In practical applications, a waterproof card paper containing polysilazane usually requires the following technologies:

[0004] 1. High-quality card paper substrate, which provides basic paper strength and texture; card paper substrate has good flatness and flexibility, can adapt to subsequent processing such as printing and cutting, and provides a stable adhesion foundation for polysilazane-coated carbon nanotube coating.

[0005] 2. Environmentally friendly production technology complies with relevant environmental standards; during the production process, environmentally friendly raw materials and production additives are selected to reduce pollution to the environment and ensure that the card paper has good environmental friendliness throughout its entire life cycle.

[0006] Currently, to protect playing card paper, manufacturers employ a variety of waterproofing methods. Some use standard waterproof coatings, which offer only basic waterproofing but fall short in terms of anti-fouling, high-temperature resistance, fatigue resistance, and antioxidant properties. Others employ lamination, which, while somewhat protective, is prone to blistering and peeling, significantly impacting the cards' flexibility. Some manufacturers have experimented with adding other functional additives, but these often suffer from poor compatibility or persistent effects.

[0007] However, there is a problem with the above method, that is, the comprehensive protective performance of the card paper is poor, especially when facing complex and changeable usage environments, such as humid environments, high temperature environments or frequent use scenarios, the card paper is easily damaged, affecting its service life and use effect. In response to this problem, the present application proposes a solution, designing a card paper with a waterproof layer 1, an outer waterproof layer and a waterproof layer 2 made of polysilazane coated carbon nanotubes. Polysilazane itself has good room temperature curing properties and can quickly form a protective layer on the surface of the card paper, giving the card paper good waterproof and anti-fouling properties. The coated carbon nanotubes are combined with other materials to further give the card paper certain high temperature resistance, fatigue resistance and antioxidant properties, greatly improving the comprehensive protective performance of the card paper, enabling it to maintain a good state in various harsh environments, extending the service life of the card, and improving the quality and value of the card.

Pattern layers are printed on the paper medium layer 12 and the second paper medium layer 13 respectively, and an adhesive layer is provided on the paper medium layer 12 and the second paper medium layer 13. The surfaces of the paper medium layer 12 and the second paper medium layer 13 without the pattern layer are bonded, and then the pattern layers of the paper medium layer 12 and the second paper medium layer 13 are bonded to the first protective layer 11 and the second protective layer 14 respectively. Then, the first protective layer 11 is bonded to the waterproof layer 1, and the outer waterproof layer 15 is sleeved on the periphery of the bonding group of the first protective layer 11, the paper medium layer 12, the paper medium layer 2 13, and the second protective layer 14. The outer waterproof layer 15 is bonded to the waterproof layer 1, and the second protective layer 14 and the outer waterproof layer 15 are bonded to the waterproof layer 2 16.

The four corners of the waterproof layer 1, the outer waterproof layer 15 and the waterproof layer 2 16 are provided with chamfers, thereby effectively protecting users from scratches.

[0027] How it works

[0028] In the first step, when making waterproof card paper containing polysilazane, a pattern layer is printed on each of the paper medium layer 12 and the paper medium layer 2 13, and an adhesive layer is provided on each of the paper medium layer 12 and the paper medium layer 2 13. The paper medium layer 12 and the paper medium layer 2 13 are bonded together without the pattern layer. Then, the pattern layers of the paper medium layer 12 and the paper medium layer 2 13 are bonded to the first protective layer 11 and the second protective layer 14 respectively. Then, the first protective layer 11 is bonded to the waterproof layer 1, and the outer waterproof layer 15 is sleeved on the first protective layer 11 and the paper medium layer 12. The outer periphery of the paper medium layer 2 13 and the second protective layer 14 are bonded to each other, the outer waterproof layer 15 is bonded to the waterproof layer 1 1, and the second protective layer 14 and the outer waterproof layer 15 are bonded to the waterproof layer 2 16. The card paper is completed. By designing the waterproof layer 1 1, the outer waterproof layer 15 and the waterproof layer 2 16 as polysilazane-coated carbon nanotube materials, polysilazane itself has good room temperature curing performance. At the same time, in addition to giving the card paper good waterproof and anti-fouling properties, the coated carbon nanotubes combined with other materials can also give the card paper certain high temperature resistance, fatigue resistance and antioxidant properties.

[0029] In the second step, when the waterproof card paper containing polysilazane is used, in order to improve the waterproofness of the side of the card, the structure of the paper medium layer 12 and the paper medium layer 2 13 is improved. The first protective layer 11 and the second protective layer 14 are added on both sides of the paper medium layer 12 and the paper medium layer 2 13. At the same time, the waterproof layer 1 and the waterproof layer 2 16 protect the first protective layer 11, the paper medium layer 12, the paper medium layer 2 13, and the second protective layer 14. When the card contacts water, it can prevent the water from wetting the card, thereby playing a waterproof role. However, an outer waterproof layer 15 is provided between the waterproof layer 1 and the waterproof layer 2 16. The outer waterproof layer 15 protects the first protective layer 11, the paper medium layer 12, and the paper medium layer 13. The outer periphery of the second layer 13 and the second protective layer 14 is protected to achieve a completely waterproof effect on the side of the card. At the same time, in order to prevent the user from scratching the hand due to the sharp edge of the card when using it, the outer edges of the exposed surfaces of the waterproof layer 1 and the waterproof layer 2 16 are provided with smooth arc surfaces, and the four corners of the waterproof layer 1, the outer waterproof layer 15 and the waterproof layer 2 16 are provided with chamfers, thereby effectively protecting the user from scratches. By designing the outer edges of the waterproof layer 1 and the waterproof layer 2 16 of the waterproof card paper containing polysilazane as arc surfaces, and designing the four corners of the waterproof layer 1, the outer waterproof layer 15 and the waterproof layer 2 16 as chamfers, it is avoided that the sharp edge of the card scratches the hand, thereby effectively improving the protection of the card.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments.
