Embodiment Construction

[0035] The present invention will be further described below in combination with specific embodiments.

[0036] The infrared low emissivity coating provided by the invention has a preparation process as follows:

[0037] Step 1: Prepare red paste. The red slurry is mixed with iron red, resin and solvent with an average particle size between 1 and 5 microns according to the mass ratio of 30:60:10. After being ground by a sand mill for 4 hours, an amount equivalent to iron red, resin and 0.1-0.3% anti-sedimentation agent of the total mass of the three solvents.

[0038] Step 2: Prepare yellow slurry. The yellow slurry is mixed with disazo organic yellow with an average particle size between 1 and 5 microns, resin and solvent according to the mass ratio of 30:60:10, after being ground by a sand mill for 4 hours, adding the equivalent of bis The anti-sedimentation agent is made of 0.1-0.3% of the total mass of azo organic yellow, resin and solvent.

[0039]Step 3: Prepare the ...

Abstract

An infrared low-emissivity coating material and a preparation method thereof belong to the technical field of functional materials. The infrared low-emissivity coating material comprises the following components by weight: 0.8 to 1 part of red slurry, 2 to 4 parts of yellow slurry, 1 to 3 parts of dispersing slurry of sheet aluminium powder, 35 to 37 parts of dispersing slurry of sheet aluminium powder coated with silicon dioxide or ferric oxide, 50 to 58 parts of solvent, 3 to 5 parts of curing agent and 0.1 to 0.3 part of flatting agent. The infrared low-emissivity coating material provided by the invention can simulate the spectral reflection curve of the northern ocher background, wherein a near infrared band has higher solar reflectivity, the average emissivity of a thermal infrared band of 3 to 5 Mum is lower than 0.35, and the average emissivity of a thermal infrared band of 8 to 14 Mum is lower than 0.45; and industrial production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and relates to an energy-saving and environment-friendly architectural decoration coating, an infrared low-emissivity coating for infrared camouflage and a preparation method. Background technique [0002] With the rapid development of industrial production, the energy problem has increasingly become a prominent contradiction that plagues social and economic development. Therefore, while emphasizing the improvement of productivity, people are paying more and more attention to the issue of energy consumption. Energy conservation and consumption reduction, energy conservation and environmental protection, energy efficiency ratio, etc. have become social hot words, and various technologies to improve energy efficiency have also become hot technologies. [0003] Optical studies have shown that the more reflective an opaque object, the lower the emissivity. Therefore, under visible light...
