Abstract

The invention discloses safe and nontoxic oil-in-water type emulsified medium oil ink. The safe and nontoxic oil-in-water type emulsified medium oil ink comprises raw materials as follows: dye and / or pigment type color paste, an oily solvent, a water-based solvent, a compound emulsifier, a corrosion inhibitor, a surfactant, a diffusant, a thickener and a convergent emulsifier. The raw materials are subjected to steps of homogeneous emulsification by an aqueous phase material, homogeneous emulsification by an oil phase material and combined emulsification by the two materials, and the safe and nontoxic oil-in-water type emulsified medium oil ink is obtained. The safe and nontoxic medium oil ink has the advantages that the writing feeling is extremely lubricating, handwriting cannot be blurred, and lines are uniform and continuous.

Description

technical field [0001] The invention relates to the technical field of medium ink, in particular to a safe and non-toxic oil-in-water emulsified medium ink. Background technique [0002] Most of the ballpoint pens commonly used at present are oily ballpoint pens or neutral ballpoint pens. Although oil-based ballpoint pens are lubricated, the handwriting is easily pasted and cannot be preserved as a file. Although neutral ballpoint pens write smoothly, the feel is not as lubricated as oil-based, and the stability is not good. Sequential situations happen. Contents of the invention [0003] The purpose of the present invention is to provide a safe and non-toxic oil-in-water emulsified medium ink. The oil-in-water emulsified medium ink utilizes oily solvents, water and hydrophilic solvents without any toxic and side effects, and obtains a homogeneous emulsification treatment. A kind of oil-in-water emulsion medium ink that can use dyes as colorants and pigments as colorants...
