Novel environment-protection gel pen ink and preparation method thereof

Abstract

The invention relates to a novel environment-protection gel pen ink. The novel environment-protection gel pen ink mainly comprises the following components in parts by weight: 8 to 12 parts of pigment, 35 to 40 parts of solvent, 4 to 8 parts of thickener, 5 to 10 parts of dispersant, 0.3 to 1 parts of surfactant, 0.2 to 1.5 parts of defoaming agent, 0.2 to 5 parts of flavor enhancer, 0.5 to 5 parts of silicone emulsion, 0.2 to 1.2 parts of ethylene glycol, 0.2 to 1.2 parts of benzo-triazole, 1.5 to 2.5 parts of sodium benzoate, 10 to 15 parts of polyethylene glycol, and 0.3 to 3 parts of pH (potential of hydrogen) adjuster, wherein the pigment is crushed by a grinding technology, and the fineness of crushed pigment is nanometer level; the solvent is a mixture of water-soluble acrylic resin emulsion and deionized water; the thickener is a mixture of xanthan gum, alkaline soluble type expansion acrylic acid, and lauryl sodium sulfate according to equal ratio; the dispersant is sodium hexametaphosphate; the surfactant is a mixture of siloxane and BD-3085; the flavor enhancer is extracted from a mixture of ethanol-soaked lemon thyme, lemon grass, rosemary, mint and sweet basil. The novel environment-protection gel pen ink has the advantages that the writing is smooth and lubricating, the fragrance is contained, the mind refreshing effect is realized, the ink disconnecting is avoided, and the beneficial and harmless effect to human body is realized.

Description

technical field [0001] The invention relates to a novel environment-friendly gel pen ink and a preparation method thereof. Background technique [0002] Gel pens have a large market in our country with a large population. The most important part of a gel pen is the ink of the gel pen except for the nib. The viscosity of gel pen ink medium is between water and oil, and there must be appropriate viscosity, surface tension, and pH value to ensure that the pen is smooth and does not leak, and that the ink is light-resistant, water-resistant, heat-resistant, cold-resistant, and moisturizing. Penetration, at the same time, it is necessary to solve the stability of the ink, so that the ink will not deteriorate, delaminate or precipitate after a long period of storage, and it must also ensure the safety of the ink, which is non-toxic and non-corrosive. However, gel pen inks are mostly prepared with organic solvents, and their viscosity is lower than that of oil-based ballpoint pen...

Problems solved by technology

However, gel pen inks are mostly prepared with organic solvents, and their viscosity is lower than that of oil-based ballpoint pen inks and thicker than water-based inks. However, general organic solvents such as ethers or alcohols are volatile, low-toxic or toxic, and long-term use. Ink is harmful to the human body
