Problems solved by technology

[0004] 1. When used, a large amount of volatile gas will be produced, which has a pungent smell and is highly toxic, which is harmful to human health
[0005] 2. The price of chemical raw materials used in solvent-based inks is relatively high, and the volatility of the solvent is extremely strong. The solvent loss in the process of production and use is large, resulting in a waste of energy
[0006] 3. The organic solvents used are highly volatile, flammable, and explosive dangerous chemical raw materials, which require strict management in production, storage, and transportation, and are very dangerous

Abstract

The invention relates the aquosity ink, comprising dispersing agent, white carbon black, light calcium carbonate, detaching agent, colourant, and water. The invention has the advantages of innocuous, energy conservation and safety.

Description

technical field [0001] The invention relates to a water-based ink, in particular to a water-based ink specially used for whiteboard markers. Background technique [0002] Water-based ink has a history of many years, is a mature technology, and has a large number of literature reports. Generally speaking, water-based inks are composed of dyes, water-soluble organic solvents, additives (including stabilizers, wetting agents, color enhancers, water-resistant agents, etc.) The choice of additives varies. These water-based inks are all inks for writing on paper, do not have erasability, and are not suitable for blackboard writing pens. [0003] The whiteboard markers sold and used in the domestic and foreign markets all adopt solvent-based inks, mainly with ethanol, acetone, methyl alcohol or similar chemical raw materials as solvents. Solvent-based inks have the following disadvantages: [0004] 1. When used, it will produce a large amount of volatile gas, which has a pungen...
