example 1

[0026] The formula and mass percentage of environment-friendly medium oily ballpoint pen ink are as follows:

[0027] Environment-friendly alcohol-soluble (black) 23%

[0028] Ethylene glycol phenyl ether (environmental protection type) 36%

[0029] DBE 18%

[0030] High softening point epoxy resin 8%

[0031] Aldehyde resin 8%

[0032] Triethanolamine 2%

[0033] Polyvinylpyrrolidone 5%

[0034] The preparation process of the above formula is: first put the mixed solvent (ethylene glycol phenyl ether (environmental protection type) and DBE) and anti-sagging resin (high softening point epoxy resin and aldehyde ketone resin) into the reactor according to the formula, and heat up to 115 Stir at ℃ until the anti-sagging resin is completely dissolved, then add alcohol-soluble dye (environmental protection alcohol-soluble (black)) and pH regulator (triethanolamine), reactive diluent (polyvinylpyrrolidone) in sequence, mix and stir evenly, and then After the high-speed centrif...

Abstract

The invention relates to ball pen writing ink, in particular to environmentally-friendly medium oily ball pen ink with ultralow viscosity. The ink comprises the following components in percentage by mass: 20 to 30 percent of alcohol-soluble dye, 45 to 55 percent of mixed solvent, 15 to 20 percent of anti-sagging resin, 2 percent of pH adjustor and 5 percent of active thinner. Compared with the prior art, the invention has the advantages that: the fluidity of the ink is improved by greatly reducing the kinematic viscosity of the ink so as to improve the writing fluency; and meanwhile, novel environment-friendly raw materials are adopted so that the prepared product meets the latest international ISO 787 / 9 and EN71-9 environmentally-friendly standards.

Description

Technical field: [0001] The invention relates to a ball-point pen writing ink, in particular to an environment-friendly and ultra-low viscosity environment-friendly medium-oil ball-point pen ink. Background technique: [0002] At present, the viscosity of ballpoint pen inks produced domestically and internationally in China is generally 8,000 to 10,000 mPa.s, and the viscosity is relatively high. The purpose is to prevent the ink from leaking from the pen tip at ordinary times. However, the higher viscosity leads to lower ink output when writing with ballpoint pens, and the fluidity cannot be compared with neutral inks and water-based pens. In addition, the environmental protection requirements of ballpoint pen inks produced in China only meet European EN71-3 and American ASTM F963- 08 standard, it cannot meet the latest international ISO 787 / 9 and EN71-9 environmental protection standards, so it cannot meet the requirements of many domestic manufacturers to export to the EU...
