Problems solved by technology

[0002] In the traditional ink manufacturing industry, a large number of dyes with high color strength and good water solubility are selected. Pigment-based inks are valid for up to two years from the date of manufacture, so writing is not durable and cannot be used to make records in archive documents, while pigment-based inks have a good reputation of never fading, which can basically meet the needs of archive documents. requirements, and thus has been vigorously promoted in recent years
However, the penetrability of the lines when writing with pigment-based inks is not as good as that of dye-based inks, that is, its capillary action on paper is poor, so the writing resistance of pigment-based inks is poor, and in addition, fouling and pen blockage often occur. There may even be precipitation

Abstract

A built water ink and its production are disclosed. The built water ink consists of dye 3-5wt%, pigment 3.5-7wt%, glycerol 10-20wt%, ethanediol 6-13wt%, disperser 0.3-1wt%, pH regulator 3-7wt%, emulsifier 0.2-0.5wt%, preservative 0.2-0.3wt%, acrylic resin soft 1# 0.5-1.0wt%, and residual pure water. It achieves moderate color, ink mark rapid dry, no ink point, and good sun-proof and anti-corrosive performance.

Description

technical field [0001] The invention relates to a stationery product, in particular to a water-based ink, and also to a production method thereof. Background technique [0002] In the traditional ink manufacturing industry, a large number of dyes with high color strength and good water solubility are selected. Pigment-based inks are valid for up to two years from the date of manufacture, so writing is not durable and cannot be used to make records in archive documents, while pigment-based inks have a good reputation of never fading, which can basically meet the needs of archive documents. Therefore, it has been vigorously promoted in recent years. However, the penetrability of the lines when writing with pigment-based inks is not as good as that of dye-based inks, that is, its capillary action on paper is poor, so the writing resistance of pigment-based inks is poor, and in addition, fouling and pen blockage often occur. There may even be a phenomenon of precipitation. C...
