Abstract
The invention discloses a preparation method of environmentally-friendly easily-erasable liquid teaching writing ink and color paste used therein. By using the writing ink disclosed by the invention together with a silver grey flat gloss projection writing board and other high gloss writing boards, the problem of severe dust pollution caused by writing with chalks in the teaching process in most schools in China can be solved completely, and healthy school construction in China is promoted. The writing ink comprises resin, pigments, aids, edible ethanol and the like. When a writing pen (water storage core type or direct liquid type) filled with the writing ink is used for writing on white boards or colored boards (suitable for high gloss and flat gloss) made of enamel, baking varnish, sticking plastic and the like, the advantages of smooth writing, easiness for erasing, freeness from dust pollution and the like are achieved. The writing ink has soft color and luster, and is various in colors, so that students can a keep good visual psychology state; and by using the writing ink for a long time, the health of teachers and the students is facilitated.
Description
Technical field
The present invention relates to a kind of making method of easily erasing type liquid teaching writing ink
Background technology
At present, the ubiquitous problem of teaching equipment and the drawback of the use of the vast school of China are broadly divided into following several kinds:
