AI Technical Summary

Technical Problem

Existing inks used for color laser printing have poor acid and alkali resistance and are easily damaged by acid or alkali during the cleaning process, affecting the color of the finished product and production efficiency.

Method used

Use color acid and alkali-resistant laser printing ink composed of methyl ethyl ketone, isopropyl alcohol, curing agent (such as aliphatic polyamine) and glycidyl ether epoxy resin, and disperse it evenly through stirring and grinding to improve the acid resistance of the ink Alkaline properties.

Benefits of technology

It significantly improves the acid and alkali resistance of laser printing inks, ensures the richness and clarity of printed products, and overcomes the vulnerability of existing inks to damage in acid and alkali environments.

Abstract

The invention discloses a colorful acid and alkali resistant laser printing ink and a preparation method thereof. The printing ink is composed of the following components in parts by weight: 0 to 30 parts of butanone, 10 to 30 parts of isopropanol, 2 to 6 parts of curing agent, 10 to 15 parts of pigment, and 10 to 30 parts of glycidyl ether epoxy resin. The glycidyl ether epoxy resin is adopted to produce the printing ink, aliphatic polyamine is further chosen as the curing agent, the acid and alkali resistant performance of the printing ink is strengthened through optimizing the formula, thus the shortage that the colorful laser printing ink is lost when being mixed with acid and alkali is overcome, moreover, the color of the laser printing product is more abundant, and the patterns are more clear.
