The ink makes writing smooth on paper, achieves a writing-on-erasing effect, can be adapted to kinds of paper for writing and be erased by the eraser on kinds of paper, and keeps test paper clean.

Description

A kind of ink that can use erased by rubber

Technical field:

The present invention relates to the real technical field of ink, be specifically related to a kind of ink that can use erased by rubber.

Background technology:

Now increasing student uses gel ink pen, ballpoint pen writes, and they need not frequent blotting, but can write out the effect of fountain pen word, therefore be subject to liking of students very much.But in the use procedure of reality, the writing of common gel ink pen, ballpoint pen is but difficult to erasing.And students there will be the situation of clerical error in actual use unavoidably, students uses correction fluid or correction tape to carry out the amendment of volume face, often causes the untidy of volume face, brings inconvenience to teacher comment operation.The evil spirit erasable ink occurred at present on the market cannot be write after wiping again, and written assignment can stay next white space.

Summary of the invention:

In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it mixes by following composition and mass ratio: sorbyl alcohol 2.5-5 part, thickening material 1.2-2 part, dispersion agent 0.5-2 part, wetting agent 0.2-0.5 part, rust-preventive agent 0.5-1 part, sterilant 0.5-1 part, rubber erasable pigment powder 15-32 part, sulfonated lignin 2 parts, pure water 55-70 part.

Ink of the present invention fluent writing on paper, namely writes and namely wipes, and can adapt to multiple paper and write, and multiple paper all can use rubber wipe, and keeps volume face clean and tidy.
