Graphene modified ink and preparation method thereof

Abstract

The invention provides graphene modified ink and a preparation method thereof. The graphene modified ink is composed of the following raw materials: resin, pine-soot ink or soot ink, a dispersing agent, a wetting agent, a stabilizer, graphene and water. The graphene modified ink has good antibacterial, mildew-proof and antiviral properties and good smooth writing hand feeling, and the wetting ductility and binding power of the ink are well balanced.

Description

technical field [0001] The invention belongs to the field of ink production for calligraphy and painting, and in particular relates to a graphene-modified ink and a preparation method thereof. Background technique [0002] At present, the main components of ink on the market are smoke ink and perishable animal glue as the main raw materials, so it is necessary to add spices and phenol, but the spices and phenol themselves have obvious disadvantages: 1. The spice itself will volatilize after a long time, The fragrance will gradually fade until it disappears; 2. The spice itself has a certain toxicity, and there is a requirement for a blending ratio when used; 3. The cost of the spice is generally relatively high; 4. The toxicity of phenol will cause harm to the human body and the environment. Serious hazard, can cause pollution to water and air. [0003] CN107266977 A discloses a kind of antibacterial functional ink and its preparation method and application. It is formed by...

[0002] At present, the main components of ink on the market are smoke ink and perishable animal glue as the main raw materials, so it is necessary to add spices and phenol, but the spices and phenol themselves have obvious disadvantages: 1. The spice itself will volatilize after a long time, The fragrance will gradually fade until it disappears; 2. The spice itself has a certain toxicity, and there is a requirement for a blending ratio when used; 3. The cost of the spice is generally relatively high; 4. The toxicity of phenol will cause harm to the human body and the environment. Serious hazard, can cause pollution to water and air

However, on the one hand, the antibacterial functional ink has a large amount of antibacterial materials and high cost, and the writing performance of the ink prepared by this patent is not good; The dispersibility of the pigment smoke ink is affected, changing its original composition and losing the charm of the ink itself

[0004] CN 106967332 A discloses a cerium and gelatin modified antibacterial ink and its preparation method. The antibacterial ink uses gelatin instead of bone glue. Although the antibacterial effect of the ink is improved, the improvement is limited, and the price of cerium and gelatin is relatively high. Increase the preparation cost of ink, and cerium is a heavy metal, its addition will cause irritation to the skin

[0005] CN110982343A discloses an antibacterial and antimold ink and its preparation method and application. In terms of mass percentage, the raw materials of the antibacterial and antimold ink include: water-based acrylic resin 12-18%, smoke ink 18-28%, dispersant 3-5%, wetting agent 3-6%, stabilizer 12-18% and antibacterial and antifungal agent 0.01-0.04%, the balance is water, the invention adds a variety of organic or inorganic antibacterial and antifungal agents to achieve antibacterial effect , high economical and practical, good antibacterial and antifungal effects, but these antibacterial agents may have some impact on writing performance
