Ugh This is a picture of the color change when the temperature changes suddenly.

First, the temperature-sensitive color-changing functional coating composition of the present invention includes two or more Zion pigments having different temperature ranges and colors, in particular two or more Zion pigments per 100 parts by weight of paint each contain 10 to 20 parts by weight, zinc oxide It is contained 8 to 12 parts by weight, preferably 10 to 20 parts by weight of the curing agent, it has three or more colors sequentially changed in response to the temperature changes from low temperature to high temperature or high temperature to low temperature by this composition.

Here, zinc oxide plays a role of enabling uniform color change by improving thermal conductivity of the coating surface in the state where the temperature-sensitive color change functional coating composition is coated, as well as the intention of preventing the destruction property of the Zion pigment by ultraviolet rays. It is included to perform.

In addition, when the temperature-sensitive color-changing functional coating composition of the present invention includes three Zion pigments having different colors and temperature ranges, the first Zion pigment having a first temperature range, the second Zion pigment having a second temperature range, The third Zion pigment having a third temperature range is preferably included in the same weight ratio.

Do.

In addition, the temperature-sensitive color change functional coating composition of the present invention is focused on having a sequential color change characteristics according to the temperature change through color mixing and color scheme. Therefore, in order to manufacture a temperature-sensitive color-changing functional coating composition, it is very important to determine whether or not to set the temperature-sensitive or color-sensitized color of the composition as a criterion for the expression of the properties of the Zion pigment to be included. Decisions should be made as to whether to focus on the development of properties by or on the effects of property on temperature.

That is, as shown in Figs. 2 and 3, the background color (the color of the paint or the composition obtained by adding and stirring zinc oxide to the paint) is determined, and the color and sensitivity condition of the Zion pigment at each temperature range to be blended with the color.
