Problems solved by technology

[0004] The existing reflective heat insulation coatings are mostly white, which cannot meet the color requirements of exterior wall decoration
If the color paint is adjusted according to the needs, as the color becomes darker, the absorption of sunlight by the paint film increases, which greatly reduces the efficiency of reflection and heat insulation

Abstract

The invention discloses a colorized reflection heat insulation coating. Carbon black, iron oxide red, organic yellow, phthalocyanine green, phthalocyanine blue, and other conventional common pigments are replaced by the pigments, namely nickel iron chromite black, nickel iron chromite red, cobalt blue, titanium yellow and cobalt green, so that the colorized reflection heat insulation coating can meet the demand of the external wall decoration on colors and has high reflectivity to solar energy and a good heat insulation effect. The invention also provides a color card by which a colorized coating is formed by mixing the nickel iron chromite black, the nickel iron chromite red, the cobalt blue, the titanium yellow and the cobalt green, a user can quickly mix the coating of the corresponding colors according to the pigment formula corresponding to each color in the color card, and the color card is convenient to use.

Description

technical field [0001] The invention relates to a color paint and a paint color card, in particular to a color reflective heat-insulating paint and a color card thereof. Background technique [0002] The sun radiates huge energy to the earth all the time, and most of the solar energy is in the visible light and near-infrared regions. According to the wavelength, it can be divided into three parts, that is, the ultraviolet region of 0.2~0.4μm accounts for 5% of the solar energy, the visible light region of 0.4~0.72μm accounts for 45% of the solar energy, and the near infrared region of 0.72~2.5μm accounts for 5% of the solar energy. 50% of the sun's energy. It can be seen that the solar energy is mainly concentrated in the visible light and infrared light regions with a wavelength of 0.4-2.5 μm. In this wavelength range, the higher the reflectivity, the better the thermal insulation effect. [0003] Any substance has the property of reflecting or absorbing certain waveleng...
