This invention discloses a pigment-based neutral red ink, its preparation method, and its applications. The pigment-based neutral red ink, by mass percentage, comprises the following components: 2-10% red organic pigment, 0.5-7% dispersant, 5-25% humectant, 0.05-0.2% polyvinylpyrrolidone, 1-10% penetrant, 0.1-1.5% preservative, 0.1-4% pH adjuster, 0.1-0.5% defoamer, and the balance deionized water. This invention's pigment-based neutral red ink solves the technical problem of easy sedimentation of red pigments through ultra-fine pigment dispersion and the combination of stabilizers, allowing the ink to remain stationary for extended periods without separation. Furthermore, the use of a special humectant combination ensures that the ink does not dry out at the pen tip without affecting its quick-drying performance; the ink exhibits excellent rheological properties, writes smoothly without clogging the pen, and has high color vibrancy. The formulation of this invention is environmentally friendly, primarily using water as a solvent, reducing the use of volatile organic compounds.

The invention discloses a carbon adsorption ink preparation process, which belongs to the technical field of carbon adsorption ink, and specifically comprises the following steps: a) preparing raw materials including bamboo charcoal, pine smoke and hide glue; b) adding auxiliary materials; c) preliminarily mixing all the raw materials in the step a) and the step b); d) further grinding, stirring, precipitating and filtering the preliminarily mixed raw materials by adopting an ancient ink preparation process; e) before compression molding, further blending the ink raw materials obtained in the step d); f) carrying out compression molding on the blended ink raw materials in the step e); and g) carrying out quality detection and screening on the pressed and molded carbon adsorption ink blocks or carbon adsorption ink strips. By accurately proportioning the bamboo charcoal, the pine smoke and the hide glue and adding various elaborately selected auxiliary materials, the stability and the adsorption performance of the ink are improved, and the ink is endowed with good writing smoothness, color and unique health care functions.
