Ball-point pen ink

Abstract

The invention relates to ball-point pen ink which comprises the following components in parts by mass: 25-40 parts of n-1,4-polyisoprene, 10-20 parts of glycol, 15-30 parts of color carbon black, 5-10 parts of glycol ether, 2-6 parts of fatty acid, 1-4 parts of sorbitol, 1-4 parts of triethylene tetramine, 0.5-2 parts of glycerol, 0.5-1 part of sodium benzoate, 0.1-0.4 parts of sodium glucoheptonate and 50-60 parts of pure water. The ball-point pen ink can be wiped in first 7-10 days on paper, then can be hardened into marks which cannot be removed permanently, has excellent water fastness and sun-proof fastness, and achieves fluent writing.

Description

Technical field [0001] The present invention involves a kind of ink, especially for a ballpoint pen ink. Background technique [0002] The ballpoint pen (or atomic pen), uses a thick thick ink, rely on the steel balls that are freely rotated on the pen head to bring out a writing tool on the paper.There is no need to irrigate the advantages of ink, and the price is relatively low, which is a popular world in the past few decades. [0003] The consumption value of the ink consumption of the ink with the ink and the ballpoint pens of the ballpoint pen is 0.64 ~ 1.6mg / cm2.The depth and width of the lines of preservation environment and writing state are difficult to send. Invention content [0004] Solved technical problems: For the disadvantages of the ink are easily wiped off, the water immersion fastness and sun resistance and the writing performance are not fluent, it provides a fluent writing performance to prevent fast dry and good ink stability.Essence [0005] Technical sol...
