Embodiment 1

[0032] The nano-infrared up-conversion material is added to the pulp fiber, and the weight part of the nano-infrared up-conversion material is 0.5-30, and the corresponding weight part of the pulp is 99.5-70, and the total weight of the two is 100.

[0033] The nano-infrared up-conversion material has good physical and chemical resistance. It can be dispersed in the pulp, or it can be added to the fixed position of the pulp. When making paper, the nano-infrared up-conversion material will be naturally fused in the fibers of the pulp, and the paper will be formed. Afterwards, the anti-counterfeiting material will be covered with tough fiber, which is inlaid in the paper and is not easy to detach. It looks like ordinary rice paper in appearance, but its anti-counterfeiting characteristics can be identified with special testing equipment. It has the characteristics of concealed, durable and easy to identify anti-counterfeiting characteristics.

[0034] The anti-counterfeiting mate...

Embodiment 2

[0036] The difference between this example and Example 1 is that the nano-infrared up-conversion material is added to the slurry and at the same time a reinforcing agent is added to improve the adhesion effect of the nano-infrared up-conversion material on the rice paper. The infrared nano-upconversion material used in this example The weight part of the conversion material is 0.5-30, the reinforcing agent used is fumed silicon dioxide, the weight part of the fumed silicon dioxide is 0.1-10, and the weight part of the pulp is the balance, totaling 100.

[0037] In this embodiment, the reinforcing agent can also be gum arabic, the weight portion of gum arabic is 0.1-10 parts, and the weight part of pulp is the balance, totaling 100 parts. The strengthening agent can also be gelatin, and the weight portion of gelatin is 0.1-10 parts, and the weight of pulp is the balance, totaling 100 parts.

[0038] During papermaking, the nano-infrared up-conversion material is combined with t...

Embodiment 3

[0041] In this embodiment, the nano-infrared up-conversion material is firstly mixed with molten synthetic fibers, and then spun into a fiber on special equipment. The diameter of the fiber is 0.1-50 μm, and the fiber containing the nano-infrared up-conversion material is added to the rice paper pulp In this process, rice paper with nano-infrared up-conversion materials was made.

[0042] The fiber selected in this embodiment is spandex fiber, the weight part of spandex fiber is 1-50 parts, the weight part of nano-infrared up-conversion material is 1-50 parts, and the total weight part of spandex fiber and nano-infrared up-conversion material is 100 parts ; The weight part of the fiber silk containing the nano-infrared up-conversion material is 1-40 parts, and the total weight part of the fiber silk of the pulp and the nano-infrared up-conversion material is 100 parts.

[0043] This embodiment also can select polyester fiber, and the weight part of polyester fiber is 1-50 part...

Abstract

The invention discloses a manufacturing technique of a durable anti-fake rice paper. The manufacturing technique includes pulping, papermaking and paper drying; during the pulping process, a durable anti-fake material is added in the sizing agent; through papermaking, the anti-fake material is completely integrated with the rice paper, and thus the rice paper shows a specific anti-fake property; the rice paper can be rapidly and exactly identified through a special detector, so that the authenticity of painting and calligraphy works can be identified. Meanwhile, an anti-fake pattern is designed on a rice paper papermaking curtain, corresponding pattern is transferred to the rice paper in papermaking; a convex anti-fake pattern is designed on the paper drying wall; corresponding pattern is transferred to the rice paper in paper drying process; through identifying specific pattern on the rice paper, the authenticity of painting and calligraphy works can be identified.

Description

technical field [0001] The invention relates to a durable anti-counterfeit rice paper and a manufacturing process thereof. Background technique [0002] Xuan paper is flexible, fine and even, and durable in color. It is traditional Chinese handmade painting and calligraphy paper. For a long time, the authenticity of calligraphy and painting works has been a persistent and universal social problem. Therefore, the anti-counterfeiting of rice paper is the key to the authenticity of calligraphy and painting works. one of the important components. The identification of traditional calligraphy and painting works mainly focuses on the two aspects of artistic form and material form of calligraphy and painting works, and has high requirements for the experience and knowledge level of the appraiser. With the continuous progress of society and the rapid development of science and technology, various advanced anti-counterfeiting means have also appeared at present to carry out anti-cou...
