Embodiment 1

[0012] Example 1, in the container, add 55 parts of acrylic acid copolymer, 11 parts of nano-silica, 5 parts of nano-titanium dioxide, fully stir for 20 minutes and keep warm at 30-50 ° C; Infrared Nano Coatings.

Embodiment 2

[0013] Example 2, in the container, add 62 parts of acrylic acid copolymer, 14 parts of nano-silica, 8 parts of nano-titanium dioxide, fully stir for 20 minutes and keep warm at 30-50 ° C; Infrared Nano Coatings.

Embodiment 3

[0014] Example 3, in the container, add 70 parts of acrylic acid copolymer, 16 parts of nano-silica, 10 parts of nano-titanium dioxide, fully stir for 20 minutes and keep warm at 30-50 ° C; Infrared Nano Coatings.

[0015] After testing, after adding a certain amount of specific infrared reflective material, the "calibrated" (when no reflective paint is used) the original indoor temperature is 33 degrees Celsius, and (after painting this paint) is reduced to 20 degrees Celsius. A total cooling of 13 degrees Celsius. And the experiment also shows that it only needs to be painted once, and the thickness is 0.1-0.3 mm. The cooling effect of brushing multiple layers is not significantly increased.

[0016] The above-mentioned coatings are mainly used on the outer roof and outer walls of buildings to reflect external infrared rays so as to reduce the indoor temperature. But for countries and regions with cold winters, it can be used in reverse. Both: paint on the interior wall....

Abstract

The invention relates to an infrared reflecting nano coating and a preparation method thereof, and the infrared reflecting nano coating comprises the following components: by weight, 55-70 parts of acrylic acid copolymer, 5-10 parts of nano titanium dioxide and 11-16 parts of nano silicon dioxide. The infrared reflecting nano coating is prepared by the following steps: 1, adding the 55-70 parts of acrylic acid copolymer, 5-10 parts of nano titanium dioxide and 11-16 parts of nano silicon dioxide in a mixing container, fully stirring for 20 min and keeping warm at 30-50 DEG C; and 2, at the normal temperature, cooling to room temperature to obtain the infrared reflecting nano coating. The infrared reflecting nano coating can effectively isolate infrared irradiation to reduce building energy consumption and reduce carbon emissions.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a nanometer paint reflecting infrared rays and a preparation method thereof. Background technique [0002] Sunlight is mainly composed of infrared rays, visible light and ultraviolet rays. In the contained energy, infrared rays accounted for roughly 45% of the total, visible light accounted for 45%, and ultraviolet rays accounted for 5%. Visible light itself is not hot, and the heat that people feel comes from the accompanying infrared radiation. [0003] Therefore, if there is a material that can reflect the infrared rays (energy) in sunlight in a targeted and selective manner, it can reduce the indoor temperature in summer, thereby significantly saving the use of air conditioners in summer for quite a few countries and regions. The huge energy consumption brought by cooling. Another "beneficial to the city as a whole" effect is to reduce the "heat island effect" of...
