Marking ink with strong adhesion, preparation method thereof and marking pen with strong adhesion

Abstract

The invention provides marking ink with strong-adhesion writing lines, a preparation method thereof and a corresponding marking pen. The marking pen is composed of the marking ink with strong adhesion, a fiber nib with porosity of 35-50%, and a fiber water-storage pen refill with fiber density of 0.16-0.19 g / cm<3>. The formula of the marking ink with strong adhesion is composed of a coloring agent, resin A, resin B, a humectant, a resin improvement additive and a solvent. The problem that the ink of a common marking pen with the application of single resin has poor adhesion on a writing interface and is easy to erase after wiped by a finger on individual writing interfaces can be overcome. Writing lines of the marking ink of the invention are not erased when written on writing interfaces such as PE plastic ziplock bags, PP penholder's smooth surface after wiped by fingers, are not erased on glass panes, PMMA materials, ceramic surfaces, PP smooth surfaces, PP frosted surfaces and PE films when adhesion reaches 80.0 N, and are not erased on OPP bags when adhesion reaches 70.0 N.

Description

technical field [0001] The invention relates to the field of writing instruments, in particular to a marking ink with strong adhesion to writing lines, a preparation method thereof and a marking pen containing the marking ink. Background technique [0002] A marker pen is a writing instrument for marking or marking on one or more materials such as metal, glass, plastic, enamel, and ceramics. Marking pens generally use fiber water storage cores to store ink, and use porous fiber nibs to draw ink to write. The ink used is that the writing has a certain adhesion fastness on the surface of the material, and it plays the role of marking or marking. However, the industry standard for adhesion fastness required by ordinary marker pens requires that the line mark under 4.9N on the glass plate will not be erased. The stitches of ordinary marker pens are easy to erase after wiping with fingers in actual use environments such as PE plastic ziplock bags and smooth surfaces of PP materi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of ordinary marking pen ink on the common writing interface that the adhesion fastness is not strong and that it is easy to erase after being wiped by fingers on the individual writing interface, and to provide a marking ink with strong adhesion to the stitches. By using two Resin compounding and adding additives to improve the resin to achieve the purpose of strong adhesion on the writing interface
