The color change color pigment color principle and structure:
The sensitized color change pigment is prepared from an electron transfer type organic compound system. The electron transfer type organic compound is a kind of organic chromogenic system with special chemical structure. The molecular structure of the organism is changed by electron transfer at a specific temperature, thereby achieving a color transition. This discoloration material is not only brightly colored, but also can achieve color changes from the "colored - colorless" state.
1, light resistance:
Temperature-sensitive color pigments are poor in light resistance, in the strong sun exposure will soon fade failure, so it is suitable for indoor use. Should avoid strong sunlight and ultraviolet light irradiation, this will help to extend the life of color pigments.
2, heat resistance:
Temperature-sensitive color pigments in a short time can withstand 230 ℃ high temperature (10 minutes), can be used for injection molding and high temperature curing. But the color of the pigment in the hair color and decolorization state of the thermal stability of the different stability of the former than the latter. In addition, when the temperature is higher than 80 ℃, constitute the discoloration of organic matter will begin to degrade. So the color change pigment should avoid long-term work above 75 ℃.
3, temperature difference color basic temperature: 0 ℃, 5 ℃, 10 ℃, 16 ℃, 21 ℃, 31 ℃, 33 ℃, 38 ℃, 43 ℃, 45 ℃, 50 ℃, 65 ℃, , 78 & lt; 0 & gt; C.
4, temperature change color with the temperature rise, down and repeatedly change the color. (To 31 ℃ red, for example, discoloration of 31 ° C above the colorless, 31 ℃ below the red).
