A kind of neutral ink water-soluble emulsified moisturizing lubricant and preparation method thereof

Abstract

The invention provides a water-soluble emulsification and moisture retention lubricant for neutral ink. The water-soluble emulsification and moisture retention lubricant simultaneously has moisture absorption, moisture retention and emulsification lubricity, and comprises, by weight, 1.5-4.0 parts of polyether modified silicone oil with the average number-average molecular weight of 4000-7500, and 0.5-1.0 part of water-soluble polyacrylamide with the average number-average molecular weight of 100000-300000. The water-soluble emulsification and moisture retention lubricant can realize synergistic regulation of moisture retention and lubricity of the neutral ink, realizes multifunctional regulation of the neutral ink under a low additive, and avoids the disadvantages of respective regulation and poor matching property of the neutral ink.

Description

technical field

[0001] The invention relates to an auxiliary agent for neutral ink and a preparation method thereof, in particular to a water-soluble emulsified moisturizing lubricant for neutral ink and a preparation method thereof. Background technique

[0002] Neutral ink means that the apparent viscosity of the ink is between oil-based ink (1000-2000mPa·s) and water-based ink (≤20mPa·s), with pigments or dyes (mainly black, red and blue) as colorants , the ink has both the lubricity of oil-based ink and the writing comfort of water-based ink. Compared with traditional dye-based inks, it has excellent light resistance, water resistance, temperature resistance and chemical stability. , to meet the file record requirements. Gel pen is a new type of ball-point pen products. Compared with traditional oil-based ball-point pens and water-based ball-point pens, it has the advantages of smooth writing, light and comfortable hand feeling, clear writing, good color, water and ligh...
