A kind of strong adhesion marking ink, its preparation method and strong adhesion marking pen

Abstract

The invention provides a marker ink with strong adhesion to writing lines, a preparation method thereof and a corresponding marker pen. The marking pen is composed of strong adhesive marking ink, a fiber tip with a porosity of 35-50%, and a fiber water storage core with a fiber filament density of 0.16-0.19g / cm3. The strong adhesion marking ink used has a formula consisting of colorant, resin A, resin B, humectant, resin improvement additive, and solvent. It can overcome the problem that ordinary marking pen ink uses a single resin on the writing interface with weak adhesion and is easy to erase after wiping fingers on individual writing interfaces. The writing lines can be found on the writing interface such as PE plastic ziplock bag and PP material pen holder. On the smooth surface, it is not easy to erase after wiping with fingers, and the adhesion fastness can reach glass plate, PMMA material, ceramic surface, PP smooth surface, PP frosted surface, and PE film, and the stitches under 80.0N will not be erased , OPP bag 70.0N under the characteristics of the traces will not be erased.

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
