Problems solved by technology

[0002] Usually, the ink that can be erased is a colloidal ink. Due to the incompleteness of the formula, it requires high use conditions and has certain disadvantages: high corrosion, poor moisture retention, and poor stability under high and low temperature conditions.
This requires the manufacturer to use it under specific conditions. For example, the filling equipment must be equipped with a glass pump, and the pen tip must use accessories such as ceramic balls, which increases the cost of use and various problems of instability, resulting in the inability to promote and popularize. use

Abstract

The invention discloses a pseudoplasticity water base dye type ink used for ball pens. Polyvinyl alcohol is used as the fixing agent of dye to last the color retention of writing for long; tannin is used as an important color matching component to deepen the color without causing fading; sulphuric acid is added as PH value regulator to lead the ink to be more stable and resistant to aging; organic phosphates are used as anti-rust lubricant to lead the ink not to corrode metal materials caused by reacting in various materials; and dextrine or maltodextrin used is non-toxic and safe glucide and has the property of high solubility and extremely excellent water retention when being put in water. The dye type ink can lead to the lasting retention of writing, has good anticorrosion and antirust performances as well as extremely good ageing stability and writing quality and is convenient and practical in writing, and the writing is easy to be eliminated.

Description

Technical field: [0001] The invention relates to a pseudoplastic dye ink, more particularly to a pseudoplastic water-based dye ink specially used for ballpoint pens. Background technique: [0002] Usually, the ink that can be erased is a kind of colloidal ink. Due to the incompleteness of the formula, it requires high use conditions and has certain disadvantages: high corrosion, poor moisture retention, and poor stability under high and low temperature conditions. This requires the manufacturer to use it under specific conditions. For example, the filling equipment must be equipped with a glass pump, and the pen tip must use accessories such as ceramic balls, which increases the cost of use and various problems of instability, resulting in the inability to promote and popularize. use. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned inks, and provide a nib suitable for various materials, which can writ...
