Abstract

The invention discloses an ink that can dissipate automatically. The composition includes 2-5 parts of lye, 10-20 parts of phenolphthalein, 1-3 parts of glycerin, 0.5-2 parts of methanol, 3,3-bis (N-octyl-2-methylindole) phthalide 5-10 parts, PEG600 1-5 parts, K 2 SO 4 1 to 3 parts, Co(NO 3 ) 2 0.5~0.8 parts, K 2 CrO 4 0.1-0.5 parts, 0.1-1 parts of film-forming agent, 0.1-0.5 parts of defoamer, 0.1-0.4 parts of cyclodextrin and 80-120 parts of water. The invention also discloses a preparation method of the self-dissipating ink. The self-dissipating ink of the present invention has strong adhesion, uniform ink output, non-diffusion, and can adhere to substrates such as paper, fiber, and plastic; meanwhile, the ink can quickly fade under sunlight, which promotes the adhesion of substrates. Reusable and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an ink that can dissipate automatically and a preparation method thereof. Background technique [0002] Ink is a liquid that contains pigments or dyes and is used for writing, drawing or marking. Common inks include red ink, blue ink, yellow ink, green ink, black ink, etc., with colorful colors and various types. Among them, inks of various colors will have different ink components as the color changes and the color depth changes. [0003] However, the existing inks have insufficient adhesion. For example, common digitally printed train tickets often lose color during use due to the poor adhesion of the ink stains, and the ink stains also pollute the hands and clothing of users. In addition, there is another defect in common ink, that is, the ink cannot be dissipated, which affects the reuse of marking paper or cloth. Contents of the invention [0004] In order to overcome the d...
