Embodiment 1

[0012] Embodiment 1, the aqueous sol that 10 parts of nano-zirconia and 4 parts of nano-titanium dioxide photocatalyst mixing powders are made; Add 60 parts of acrylate copolymers, 10 parts of hollow microspheres, 15 parts of organic solvents, nano-zirconia The aqueous sol prepared by mixing the powder with the nano-titanium dioxide photocatalyst is fully stirred for 40 minutes; it is cooled to room temperature at room temperature, and the desired coating is obtained.

Embodiment 2

[0013] Embodiment 2, the aqueous sol that 20 parts of nano-zirconia and 10 parts of nano-titanium dioxide photocatalyst mixing powders are made; Add 70 parts of acrylate copolymers, 16 parts of hollow microspheres, 20 parts of organic solvents, nano-zirconia The aqueous sol prepared by mixing the powder with the nano-titanium dioxide photocatalyst is fully stirred for 40 minutes; it is cooled to room temperature at room temperature, and the desired coating is obtained.

Embodiment 3

[0014] Embodiment 3, the aqueous sol that 15 parts of nano-zirconia and 7 parts of nano-titanium dioxide photocatalyst mixing powders are made; Add 65 parts of acrylate copolymers, 13 parts of hollow microspheres, 18 parts of organic solvents, nano-zirconia The aqueous sol prepared by mixing the powder with the nano-titanium dioxide photocatalyst is fully stirred for 40 minutes; it is cooled to room temperature at room temperature, and the desired coating is obtained.

[0015] 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. In this way, the infrared rays that are about to escape from the room can be reflected back (back to the room). In other words, the indoor infrared rays can be kept indoors as much as possible, thereby reducing the heating and energ...

Abstract

The invention relates to an antibacterial infrared-reflection coating and a preparation method thereof, and the antibacterial infrared-reflection coating comprises the following components: by weight, 60-70 parts of a base material, 10-20 parts of nano zirconia, 4-10 parts of a nano titanium dioxide photocatalyst, 10-16 parts of hollow microbeads and 15-20 parts of an organic solvent. The infrared-reflection heat-insulation coating is prepared by the following steps: preparing an aqueous aerosol with mixed powder of the 10-20 parts of the nano zirconia and the 4-10 parts of the nano titanium dioxide photocatalyst; adding the 60-70 parts of the base material, the 10-16 parts of the hollow microbeads, the 15-20 parts of the organic solvent, and the aqueous aerosol prepared by the mixed powder of the nano zirconia and the nano titanium dioxide photocatalyst, fully stirring for 40 min; at the normal temperature, cooling to the room temperature to obtain the needed antibacterial infrared-reflection coating. The antibacterial infrared-reflection coating can effectively isolate infrared irradiation to reduce building energy consumption, the hollow microbeads are used for reducing visible light radiation, meanwhile a hollow layer is formed between coating layers to further obstruct heat to reduce carbon emissions, and the nano titanium dioxide photocatalyst can effectively sterilize.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an antibacterial infrared reflective 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 m...
