Abstract

Reversibly organic thermochromic material comprising (by weight portion) neutral red 1-10 parts, aluminum oxide 10-100 parts, hexamethylene tetramine 10-100 parts, ferrous chloride 10-100 parts. The invention realized a low-temperature reversible organic heat off-color material prepared from neutral red as a novel color former, which can be used for preparing thermal color change printing ink and coating material.

Description

A kind of reversible organic thermochromic material
Technical field
The present invention relates to thermochromic material.
Background technology
The compound, mixture of colour-change can take place when thermochromic material is meant temperature variation or be the thermochromism product that the agent of variable color index is made with them.Existing lot of research and product have been widely used in industrial sense temperature indicating degree, test and alarm element both at home and abroad; Make the usefulness of monitoring and controlled temperature in the medical treatment; Be used as color shifting ink in the publication and printing and make anti-false sign; Can be used for interior decoration, textile garment, articles for daily use, articles for children, articles for children and toy etc. in the daily life.But forefathers institute development product is complicated process of preparation mostly, and cost is higher.
Summary of the invention:
The present invention gets toluylene red 1-10g, aluminum oxide 10-100g, and vulkacit H 10-100g or iron protochloride 10-100g put in the mortar and fully grind, till the mixture colour stable.Put it in the baking oven, be heated to variable color, take out the back and stir cooling, promptly get product.
Advantages such as the present invention is the organic thermochromatic material of low-temp reversible that new chromogenic reagent is made with toluylene red, and it is simple to have preparation technology, and the big and discoloring temperature between 30-80 ℃ of colour-change sensitivity, aberration is adjustable.Can be used for preparing thermochromism printing ink and coating etc.
Products obtained therefrom performance of the present invention sees the following form.
The result of table 1 liang handicraft product
Production number colour-change color transition point/℃ colour difference sensitivity/s reversibility
I is red → blue 71 ℃ big 31 can
H brown red → ash purple 71 ℃ bigger 26 can
Product I is developer with the vulkacit H; Product I I is developer with the iron protochloride.
Specific embodiment
Example 1
Get toluylene red 2g, aluminum oxide 15g, vulkacit H 20g puts in the mortar and fully grinds, till the mixture colour stable.Put it in the baking oven, be heated to variable color, take out the back and stir cooling, promptly get product.
Example 2
Get toluylene red 2g, aluminum oxide 15g, iron protochloride 60g puts in the mortar and fully grinds, till the mixture colour stable.Put it in the baking oven, be heated to variable color, take out the back and stir cooling, promptly get product.
