Description

A kind of mark pen ink

Technical field

The present invention relates to inks fields, more particularly to a kind of mark pen ink.

Background technique

Marking pen is that one kind can submit a written statement to a higher authority writing note in paper, timber, metal, plastics, one or more materials such as ward off ceramics Number or mark pen.Marking pen is divided into permanent pen and aqueous marking pen.Aqueous marking pen can be in smooth body surface Or write on blank, it can be wiped with rag, what permanent pen was write is just not easy to wipe.

In view of chalk as teaching aid, there is serious pollution to environment, totally unfavorable to human health, chalk starts It updates: moist writing being become from stemness writing, i.e. development erasability blackboard ink.Then marking pen and its ink conduct The substitute products of chalk come into being.Marking pen belong to it is wet write xerotripsis class pen, be mark pen ink in the whiteboard surface for being covered with glaze layer On write in a manner of watercolor pencil, formed in plate face one layer thin because cellulose or trialkyl phosphate esters compound, writing is added Film can be wiped easily with dry cloth or blackboard eraser.The teaching aid is succeeded in developing already, but can not be promoted due to there are many defects.Such as: plate Face has coating easily to scratch, and reflecting rate is high, is not suitable for teaching in classroom；Ink uses organic solvent, at high cost, volatile, danger Evil health, pollution environment, writing amount is small, penetration is strong, and pollution plate face shading, the plate face service life is short etc..Mark pen ink is big Mostly it is black, is made by adding dyestuff, clipboard uses blank, since blank is easily reflective, so being difficult to promote in middle and primary schools. As the reach of science and marking pen are applied universal, the performance of mark pen ink is also being continuously improved and perfect, especially its The middle solvent as important component.Consider that more stringent requirements are proposed to it, and the selection of solvent is more from protection human health angle Add strictly, the invention proposes a kind of mark pen inks to change tradition containing the biggish ester of toxicity, ketone, benzene class organic solvent Into developing a kind of nontoxic mark pen ink, and develop to aqueous solvent direction is improved, substantially improve making for marking pen With environment, keep its application more universal.

Summary of the invention

Present invention mainly solves the technical issues of conventional white board ink be more toxic a kind of nontoxic marking pen be provided Ink, a kind of mark pen ink, which is characterized in that the mark pen ink includes following composition by weight: ethyl acetate 10~17 parts, 22~29 parts of dimethyl carbonate, 19~26 parts of diethylene-triamine pentaacetic acid, 27~33 parts of trialkyl phosphates, 10~14 parts of pigment.

Dimethyl carbonate has many advantages, such as that small toxicity, safety, pollution is small and transport is easy, and activity is good, in this hair It can cooperate with other components in bright.

Further, the composition by weight is 14 parts of ethyl acetate, 26 parts of dimethyl carbonate, diethylenetriamines 22 parts of pentaacetic acid.

Further, the pigment is phthalocyanine blue.

Further, the phthalocyanine blue is 12 parts.

Further, the trialkyl phosphates are organosilicon trialkyl phosphates.

Further, the organosilicon trialkyl phosphates are 30 parts.

Further, the ethyl acetate is that analysis is pure.

Further, the organosilicon trialkyl phosphates preparation method the following steps are included:
