Abstract

The invention discloses a thermochromic material of a malachite green-boric acid system, and a proportion confirmation test method. The thermochromatic material is a color-changing material in which substances are changed in color at different temperatures; and various thermochromic reasons such as crystal form transformation, structural change and the like of the substances at the different temperatures exist. The thermochromic material comprises, by weight, 1-3 parts of a color forming agent, 100-130 parts of a color developing agent and 10-500 parts of a solvent; the color forming agent ismalachite green; the color developing agent is boric acid; and the solvent is malonic acid, citric acid or tetradecanol. The method is used for the thermochromic material of the malachite green-boricacid system and proportion confirmation.

Description

Technical field: [0001] The invention relates to a malachite green-boric acid system thermochromic material and a ratio confirmation test method. Background technique: [0002] Thermochromic materials are a type of color-changing materials that change color at different temperatures. There are many reasons for thermochromic, such as crystal transformation and structural changes of substances at different temperatures. Thermochromic materials are used in a wide range of industries in daily production and life. Today, thermochromic materials are mainly used in the aerospace industry, temperature information temperature display, automotive industry, temperature display coating industry, clothing and daily necessities and other fields. However, thermochromic materials are inherently extensive research disciplines, with many research directions and the potential to complete scientific research results. Scientists have set their sights on thermochromic materials that are more inte...
