Embodiment 1

[0013] Example 1, put 15 parts of nano-titanium dioxide and 4 parts of nano-silicon dioxide into a grinder and grind for 15 minutes; mix the ground nano-titanium dioxide and nano-silicon dioxide to obtain a hydrosol; add acrylic acid to the mixing container 60 parts of copolymer, 10 parts of hollow microspheres, 15 parts of organic solvent, 4 parts of defoamer, the hydrosol prepared by mixing powder of nano-titanium dioxide and nano-silica, fully stirred for 15 minutes and kept at 30-50°C 20 minutes; normal temperature is cooled to room temperature, and the required thermal insulation coating is obtained.

Embodiment 2

[0014] Example 2, put 20 parts of nano-titanium dioxide and 8 parts of nano-silicon dioxide into a grinder and grind for 15 minutes; mix the ground nano-titanium dioxide and nano-silicon dioxide to obtain a hydrosol; add acrylic acid to the mixing container 70 parts of copolymer, 16 parts of hollow microspheres, 20 parts of organic solvent, 8 parts of defoamer, the hydrosol prepared by mixing powder of nano-titanium dioxide and nano-silica, fully stirred for 15 minutes and kept at 30-50°C 20 minutes; normal temperature is cooled to room temperature, and the required thermal insulation coating is obtained.

Embodiment 3

[0015] Example 3, put 17 parts of nano-titanium dioxide and 6 parts of nano-silicon dioxide into a grinder and grind for 15 minutes; mix the ground nano-titanium dioxide and nano-silicon dioxide to obtain a hydrosol; add acrylic acid to the mixing container 65 parts of copolymer, 13 parts of hollow microspheres, 17 parts of organic solvent, 6 parts of defoamer, the hydrosol prepared by mixing powder of nano-titanium dioxide and nano-silica, fully stirred for 15 minutes and kept at 30-50°C 20 minutes; normal temperature is cooled to room temperature, and the required thermal insulation coating is obtained.

[0016] After testing, after adding a certain amount of specific infrared reflective material, the "calibrated" (when no reflective paint is used) the original indoor temperature of 40 degrees Celsius, (after painting this paint) is reduced to 24 degrees Celsius. A total cooling of 16 degrees Celsius. And the experiment also shows that it only needs to be painted once, and ...

Abstract

The invention relates to an infrared-reflection heat-insulation coating and a preparation method thereof, and the infrared-reflection heat-insulation coating comprises the following components: by weight, 60-70 parts of acrylic acid copolymer, 15-20 parts of nano titanium dioxide, 4-8 parts of nano silicon dioxide, 10-16 parts of hollow microbeads, 4-8 parts of a defoaming agent and 15-20 parts of an organic solvent. The infrared-reflection heat-insulation coating is prepared by the following steps: grinding the 15-20 parts of nano titanium dioxide and 4-8 parts of nano silicon dioxide for 15 minutes; preparing an aqueous aerosol with mixed powder of the nano titanium dioxide and the nano silicon dioxide; adding the 60-70 parts of the acrylic acid copolymer, 10-16 parts of the hollow microbeads, 4-8 parts of the defoaming agent, 15-20 parts of the organic solvent, and the aqueous aerosol prepared by the mixed powder of the nano titanium dioxide and the nano silicon dioxide, stirring for 15 min, standing, and keeping warm at 30-50 DEG C for 20 min; cooling to the room temperature. The infrared-reflection heat-insulation coating can effectively isolate infrared irradiation to reduce building energy consumption, and the hollow microbeads can reduce visible radiation, and a hollow layer can obstruct heat to reduce carbon emissions.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an infrared reflective heat-insulating paint 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 has less heat, and the heat that people feel mainly comes from the accompanying infrared radiation. [0003] Therefore, if there is a material that can reflect infrared and visible light in the sun in a targeted and selective manner, it can reduce the indoor temperature in summer, thereby significantly saving many countries and regions from using air conditioners to cool down in summer. huge energy consumption. Another "beneficial to the city as a whole" effect is to reduce the "heat island effect" of large and...
