High-stability anti-blocking carbon black ink and preparation method thereof

Abstract

The invention relates to high-stability anti-blocking carbon black ink and a preparation method thereof. The high-stability anti-blocking carbon black ink comprises the following raw materials in percentage by weight: 20 percent of carbon black slurry, 10 percent of water soluble silicon oil, 5 percent of polyvinyl alcohol, 5 percent of polyvinyl acetate emulsion, 1 percent of cellulose thickener, 1 percent of polyurethane association thickener, 0.2 percent of defoamer and the balance of deionized water. The preparation method comprises the following steps of: pouring part of the deionized water into the container; adding the polyvinyl alcohol and the cellulose thickener into the container; uniformly stirring; adding the carbon black slurry, the polyvinyl acetate emulsion and the water soluble silicon oil into the uniformly mixed material in turn; diluting the polyurethane association thickener and the defoamer by using the deionized water; filling the obtained product into a container; performing detection, filtering the qualified product by using a 800-mesh electric sieve and filling the obtained product into a barrel. The ink of the invention has the advantages of making writing smooth and soft, having certain oilness, relatively high moisture holding property, preventing water evaporation, a pen point from drying and the pen point from being blocked by the carbon black; and the ink is difficult to demix or precipitate.

Description

technical field [0001] The invention relates to a carbon black ink, in particular to a high-stability anti-clogging carbon black ink, and also relates to a preparation method of the high-stability anti-clogging carbon black ink. Background technique [0002] The current carbon black ink has the advantages of no discoloration and long storage time of ink marks, but it also has the following disadvantages. The first is that the storage time of carbon black ink is short, and the ink is easy to delaminate or precipitate if it is not used for a long time. Solid matter, if the pen is not used for a long time, the carbon black will easily clog the pen tip. Contents of the invention [0003] In order to overcome the disadvantages that the carbon black is easy to block the pen tip and the ink is easy to delaminate, the invention provides a high-stability anti-blocking carbon black ink. [0004] The invention also provides a preparation method of the ink. [0005] A high stability...
