Abstract

The invention discloses a preparation method of oil-in-water type emulsified medium oil ink. The oil-in-water type emulsified medium oil ink comprises raw material dye and / or pigment type color paste, an oily solvent, an aqueous solvent, a compound emulsifier, a corrosion inhibitor, a surfactant, a dispersing agent, a thickening agent and a polymerized emulsifier. The raw materials are prepared into the oil-in-water type emulsified medium oil ink after steps of aqueous-phase substance homogenizing emulsification, oil-phase substance homogenizing emulsification and two-phase substance merge emulsification. The oil-in-water type emulsified medium oil ink is safe and non-toxic and extremely smooth in writing hand feeling, illegible writing can be avoided, and lines are uniform and continuous. The preparation method adopts a simple technology, the price of the raw materials is low, and the preparation method is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of medium ink, in particular to a preparation method of 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 preparation method of oil-in-water emulsified medium ink, which utilizes oily solvents without any toxic and side effects, water and hydrophilic solvents to obtain a Both dyes and pigments can be used as colorants in the oil-in-water emulsion medium ink. [0004] In order to solve the above problems, according to one aspect of the...
