AI Technical Summary

Problems solved by technology

However, the neutral inks researched and manufactured in my country now have low thixotropy, poor rheological properties, and poor stability, all of which lead to short cap removal time, short storage time, and poor writing performance of the manufactured pen products.
Due to the single function of traditional ink, ink users will feel tired after long-term use, which can no longer meet people's daily needs

Abstract

The invention discloses neutral ink with the refreshing and moldproof function and a preparation method and application thereof. The neutral ink is prepared from, by weight, 15-22 parts of graphite, 1-3 parts of protein binder, 3-8 parts of glyceryl triacetate, 20-28 parts of lycium barbarum, 13-18 parts of radix lithospermi, 35-42 parts of humifuse euphorbia herb and 5-10 parts of pigment. Lycium barbarum and radix lithospermi are smashed, absolute ethyl alcohol is added, sealing and stirring are performed, and a mixture A is prepared; humifuse euphorbia herb is smashed, deionized water is added, decoction is performed on a high fire, a mixture B is obtained, the mixture A and the mixture B are mixed, stirred, filtered and concentrated at vacuum, and a mixture C is obtained; graphite powder, the protein binder, glyceryl triacetate and the pigment are mixed with the mixture C, shearing and ultrasonic processing are performed, and the neutral ink is obtained. The neutral ink is good in stability and moldproof performance and smooth in writing hand feel and makes lines clear, the water leaching fastness and the light fastness of ink marks are quite outstanding, air negative ions can also be released for a long time, and the neutral ink is environmentally friendly, non-toxic and low in price.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a refreshing and anti-mildew neutral ink as well as its preparation method and application. Background technique [0002] Ink is a gel containing pigments or dyes, and ink is used for writing or drawing. Among them, the neutral ink has unique rheological properties, that is, when there is no shear force, the viscosity is very high, which can ensure that the ballpoint pen does not drip or flow; The change of shearing force is small, which can ensure continuous lubrication and uniform ink output during writing. Process parameters, compatibility between components and matching process can not only change the rheological properties of the ink, but also directly affect the stability and comprehensive application performance of the ink. That is to say, ink formulation technology is a key to determine the overall performance of neutral water exhaustion. The neutral ink water-based system...
