Embodiment 1

[0012] Example 1, the hydrosol prepared by mixing 10 parts of nano-zirconia and 4 parts of copper-containing titania silicate composite powder; add 60 parts of acrylate copolymer, 10 parts of hollow microspheres, 5 parts The hydrosol prepared by mixing powder of magnesium-aluminum composite oxide, 15 parts of organic solvent, nano-zirconia and copper-containing titania silicate complex, fully stirred for 20 minutes and kept at 30-50°C for 20 minutes; cooled at room temperature to At room temperature, the desired coating is obtained.

Embodiment 2

[0013] Example 2, the hydrosol obtained by mixing 25 parts of nano-zirconia and 15 parts of copper-containing titania silicate composite powder; add 70 parts of acrylate copolymer, 16 parts of hollow microspheres, 15 parts of The hydrosol prepared by mixing powder of magnesium-aluminum composite oxide, 20 parts of organic solvent, nano-zirconia and copper-containing titania silicate complex, fully stirred for 20 minutes and kept at 30-50°C for 20 minutes; cooled at room temperature to At room temperature, the desired coating is obtained.

Embodiment 3

[0014] Example 3, the hydrosol obtained by mixing 18 parts of nano-zirconia and 9 parts of copper-containing titania silicate composite powder; add 65 parts of acrylate copolymer, 13 parts of hollow microspheres, 9 parts of The hydrosol prepared by mixing powder of magnesium-aluminum composite oxide, 18 parts of organic solvent, nano-zirconia and copper-containing titania silicate complex, fully stirred for 20 minutes and kept at 30-50°C for 20 minutes; cooled at room temperature to At room temperature, 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 ke...

Abstract

The invention relates to a green infrared reflective coating and a preparation method thereof. The green infrared reflective coating consists of the following components in parts by weight: 60-70 parts of base material, 10-25 parts of nanometer zirconia, 4-15 parts of copper-bearing titanium oxide silicate compound, 10-16 parts of hollow microbeads, 5-15 parts of magnalium composite oxide and 15-20 parts of organic solvent. The preparation method comprises the steps of: mixing powder of 10-25 parts of nanometer zirconia with powder of 4-15 parts of copper-bearing titanium oxide silicate compound to prepare hydrosol; adding 60-70 parts of base material, 10-16 parts of hollow microbeads, 5-15 parts of magnalium composite oxide, 15-20 parts of organic solvent and the hydrosol prepared from the nanometer zirconia and the copper-bearing titanium oxide silicate compound into a mixing container, fully stirring the materials, stewing and keeping the temperature within 30-50 DEG C for 20 minutes, cooling the mixture to room temperature, and then obtaining a required insulating coating. The green infrared reflective coating disclosed by the invention effectively insolates irradiation of infrared ray and visible light and reduces energy consumption of buildings.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a green 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 medium-siz...
