Abstract

An environment-friendly water-based ink composition includes, by mass, 3-5 parts of tannic acid, 4-8 parts of gallic acid, 8-14 parts of ferrous sulfate, 2-5 parts of a pigment, 2-4 parts of sulfonicacid-type aqueous polyurethane, 8-15 parts of a modifier, 0.5-1 part of an anionic surfactant, 0.5-1 part of a mildew proofing agent, 3-6 parts of a dispersing agent, and 50-80 parts of water. With water being the solvent, damage on body health of a user and natural environment due to an organic solvent is prevented. The raw materials are toxic-free and environment-friendly materials and the ink composition is free of heavy metals. The ink composition has a reasonable formula, wherein ink produced from the ink composition has excellent smoothness and great feel during writing, is free of bleeding on paper, flocculation and dryness, and hardening and seepage on the tip of a pen. The ink composition has excellent comprehensive performance.

Description

technical field [0001] The invention relates to a writing ink, in particular to an environment-friendly water-based ink composition. Background technique [0002] With the active culture and the development of economy and trade, the demand for various fountain pen products is increasing rapidly year by year. According to incomplete statistics, the current annual output of fountain pen products in my country has far exceeded 10 billion. At present, many fountain pen inks use organic solvents as the main material, accounting for about 70-80% of the ink quality. Organic solvents are generally alcohols and esters, and some benzenes, ethers, methanol, and even acetone. These organic solvents are volatile and wasteful during use and assembly, which not only pollute the environment, but also cause harm to human health. After testing some solvent-based inks of different colors, researchers found that the heavy metals in them exceeded the standard, and there were benzene solvent re...
