example 1

[0012] Take 2g of neutral red, 15g of aluminum oxide, and 20g of hexamethylenetetramine, and grind them thoroughly in a mortar until the color of the mixture is stable. Put it in an oven, heat it until it changes color, take it out, stir it and cool it down to get the product.

example 2

[0014] Take 2g of neutral red, 15g of aluminum oxide, and 60g of ferrous chloride, and grind them thoroughly in a mortar until the color of the mixture is stable. Put it in an oven, heat it until it changes color, take it out, stir it and cool it down to get the product.

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

technical field [0001] The present invention relates to thermochromic materials. Background technique [0002] Thermochromic materials refer to compounds, mixtures that change color when the temperature changes, or thermochromic products made of them as color indicator agents. There are a large number of research results and products at home and abroad, which have been widely used in industrial temperature sensing, testing and alarm components; in medical treatment for monitoring and controlling temperature; in publishing and printing as color-changing ink and making anti-counterfeiting signs; in daily life It can be used in interior decoration, textile and clothing, daily necessities, children's products, children's products and toys, etc. However, most of the products developed by the predecessors are complex in preparation process and high in cost. Invention content: [0003] The present invention takes 1-10g of neutral red, 10-100g of aluminum oxide, 10-100g of hexam...
