Abstract

The invention discloses a kind of white board pen ink, the white board pen ink includes following composition by weight：10~17 parts of ethyl acetate, 22~29 parts of dimethyl carbonate, 19~26 parts of isopropanol, 27~33 parts of resin, 10~14 parts of pigment.

Description

A kind of white board pen ink

Technical field

The present invention relates to inks field, more particularly to a kind of white board pen ink.

Background technology

In view of chalk has serious pollution to environment, totally unfavorable to health, chalk starts as teaching aid Update：Moist writing is changed into from dryness writing, that is, develops erasability blackboard ink.Then white board marker and its ink conduct The substitute products of chalk arise at the historic moment.White board marker belongs to wet and writes xerotripsis class pen, is that white board pen ink is being covered with the whiteboard surface of glaze layer On write in a manner of watercolor pencil, thin film is formed in plate face because adding cellulose or resinae compound, writing, with dry cloth Or blackboard eraser can be wiped easily.The teaching aid is succeeded in developing already, but can not be promoted because many defects be present.Such as：Plate face has coating Easily scratch, reflecting rate is high, is not suitable for teaching in classroom；Ink uses organic solvent, and cost is high, volatile, harm health, dirt Environment is contaminated, writing amount is small, penetration is strong, pollution plate face shading, plate face short life etc..White board pen ink is black mostly, It is made by adding dyestuff, clipboard uses blank, because blank is easily reflective, so being difficult to promote in middle and primary schools.With science Development and white board marker application popularization, the performance of white board pen ink is also being updated and perfect, particularly wherein as weight Want the solvent of component.Consider that higher requirement is proposed to it, and the selection of solvent is stricter from protection human health angle, The present invention proposes a kind of white board pen ink and tradition is improved containing the larger ester of toxicity, ketone, benzene class organic solvent, works out A kind of nontoxic white board pen ink, and develop to aqueous solvent direction is improved, the use environment of white board marker is substantially improved, is made Its application is more universal.

The content of the invention

Present invention mainly solves technical problem conventional white board ink toxicity larger provide a kind of nontoxic white board marker Ink, a kind of white board pen ink, it is characterised in that the white board pen ink includes following composition by weight：Ethyl acetate 10~17 parts, 22~29 parts of dimethyl carbonate, 19~26 parts of isopropanol, 27~33 parts of resin, 10~14 parts of pigment.

Dimethyl carbonate has the advantages that small toxicity, safety, pollution is small and transport is easy, and activity is good, in this hair It can be cooperated in bright with other components.

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

Further, the pigment is phthalocyanine blue.

Further, the phthalocyanine blue is 12 parts.

Further, the resin is organic siliconresin.

Further, the organic siliconresin is 30 parts.

Further, the preparation method of the organic siliconresin comprises the following steps：

(1) 40 parts of vinyltrimethoxy silane, 31 parts of polyethylene glycol monoacrylate, EMA 17 are weighed Part, 13 parts of butyl acrylate, it is transferred to after well mixed in container, then weigh the 1.7 parts of additions of peroxide diethyl hecanoic acid t-butyl ester In said vesse, stir to form mixture, it is standby.

(2) in mass ratio 7 are used：3 weigh dimethylbenzene：Totally 80 parts of n-butanol mixed solvent, container is transferred to by mixed solvent In, when temperature is raised to 115 DEG C~125 DEG C, starts the mixture in agitation and dropping step (1), be added dropwise to complete in 4~5h, so 1~2h of insulation adds 0.3 part of peroxide diethyl hecanoic acid t-butyl ester afterwards, cools down, produces after being incubated 4~5h.

The beneficial effects of the invention are as follows：It is nontoxic, it will not be detrimental to health, while plate face will not also be damaged.

Embodiment

Embodiment 1

The preparation of organic siliconresin：

(1) 40 parts of vinyltrimethoxy silane, polyethylene glycol monoacrylate 31 are accurately weighed with SQP types electronic balance Part, 17 parts of EMA, 13 parts of butyl acrylate, it is transferred to after well mixed in beaker, then weigh peroxide diethyl 1.7 parts of hecanoic acid t-butyl ester is added in above-mentioned beaker, and it is standby that annular safety funnel is then moved to after being stirred with glass bar.

(2) SQP types electronic balance in mass ratio 7 is used：3 weigh and prepare dimethylbenzene：80 parts of n-butanol mixed solvent, will be mixed Bonding solvent is transferred in four-hole boiling flask, is placed in heating mantle and is installed reaction unit, is opened heating mantle and is opened condensed water simultaneously Dropping funel is loaded onto when temperature is raised to 115 DEG C and starts mixture in agitation and dropping step (1), is added dropwise to complete in 4~5h, Then 1~2h of insulation adds 0.3 part of peroxide diethyl hecanoic acid t-butyl ester, is cooled down after 4~5h of insulation and obtains faint yellow sticky shape Solution, it is transferred in preprepared polypropylene vial and preserves, produce.
