Problems solved by technology

Therefore, there are often poor neutral inks, and various additives cannot be matched. Therefore, when developing new neutral inks, moisturizing and lubrication are adjusted separately. However, due to the mutual influence of neutral ink moisturizing and lubricating additives, it may Destroy the stability system of neutral ink, make neutral ink products deteriorate, and affect the development of neutral ink products

preparation example Construction

[0072] The second aspect of the present invention provides a kind of preparation method of described neutral ink water-soluble emulsified moisturizing lubricant, wherein, comprise the steps:

[0073] (a) providing the components described in the present invention, and dissolving the water-soluble polyacrylamide in the mixed solvent;

[0074] (b) adding water-soluble polyether modified silicone oil to the system obtained in step (a);

[0075] (c) Grinding, dispersing and filtering the solution obtained in step (b) to obtain the water-soluble emulsified moisturizing lubricant for the neutral ink.

[0076] In a specific embodiment of the present invention, the grinding in the step (c) is carried out using a colloid mill, wherein the grinding is carried out in the colloid mill for 3-5 hours.

[0077] application

[0078] The third aspect of the present invention provides an application of the neutral ink water-soluble emulsified moisturizing lubricant in neutral ink.

Embodiment approach

[0080] In a preferred embodiment of the present invention, wherein, the neutral ink water-soluble emulsified moisturizing lubricant consists of the following components:

[0081] Water-soluble polyether modified silicone oil 1.5-4.0wt%,

[0082] Water-soluble polyacrylamide is 0.5-1.0wt%,

[0083] The mixed solvent is 94.7~97.6wt%, and the mixed solvent is a mixed solvent of ethylene glycol and deionized water; or the mixed solvent is a mixed solvent of polyethylene glycol with a low degree of polymerization and deionized water, and the low polymerization The weight-average molecular weight of polyethylene glycol is not higher than 800;

[0084] Preservatives are the balance;

[0085] And the described neutral ink water-soluble emulsified moisturizing lubricant is prepared by the following method:

[0086] (a) first dissolving the water-soluble polyacrylamide in the mixed solvent;

[0087] (b) adding water-soluble polyether modified silicone oil to the system obtained in s...

Embodiment 1

[0104] First configure a mixed solvent of ethylene glycol and water with a mass ratio of 1:8, and then dissolve polyacrylamide with an average molecular weight of 100,000 in a mixed solvent of ethylene glycol and deionized water at 50°C. After stirring for 2 hours to fully dissolve, mix and disperse, add water-soluble polyether modified silicone oil with an average molecular weight of 7500 to the system, use a colloid mill to grind, mix and disperse, grind for 5 hours, then filter, and prepare neutral ink water after standing still for 72 hours Soluble emulsifying moisturizing lubricant.

[0105] The name and content of each component are as follows:

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...
