Embodiment 1

[0020] Embodiment 1: A new type of copper-based infrared coating, through heat treatment, the compound in the coating is carbonized and metal oxidized, so as to change the infrared emissivity of the coating. The coating includes polyurethane AB material, copper powder and butyl acetate After mixing, it is prepared by the following steps:

[0021] 1) Take 30 parts by mass of copper powder, 10 parts by mass of component A of polyurethane AB material, and 10 parts by mass of component B of polyurethane AB material, put in 15 parts by mass of butyl acetate, mix and stir evenly;

[0022] 2) Take the mixed solution obtained in step 1), apply it evenly on the aluminum sheet with a pad pen to form a coating, and cure it at room temperature for 24 hours;

[0023] 3) Heat the coating after solidification in step 2) for 1 hour, and the new copper-based infrared coating can be obtained after the coating returns to room temperature.

[0024] The heating temperature in step 3) is 150°C, 25...

Abstract

The invention relates to infrared paint, in particular to novel copper-based infrared paint that is convenient in emissivity modulation and high in emissivity. According to the novel copper-based infrared paint, heat treatment is carried out to achieve compound carbonization and metal oxygenation in a coating to change the infrared emissivity of the coating. The paint is characterized by comprising a polyurethane AB material, copper powder and a butyl acetate mixture. According to the novel copper-based infrared paint, after the heat treatment at different temperatures, polyurethane is carbonized, and copper powder is oxidized to jointly change the infrared emissivity of the coating. Therefore, the prepared infrared paint has the higher emissivity and emissivity modulation performance and can be used for the fields of military development, energy conservation, environmental protection, building design and the like.

Description

technical field [0001] The invention relates to an infrared paint, in particular to a novel copper-based infrared paint with convenient modulation of emissivity and high emissivity. Background technique [0002] As an emerging material, infrared coatings can be used in the fields of military development, architectural design, energy conservation and environmental protection, among which the bonding firmness and infrared emissivity of coatings are the two most important aspects in the use of infrared coatings. Therefore, the research and preparation of infrared coatings with good bonding performance, high infrared emissivity and adjustable emissivity have been widely concerned by people. [0003] At present, although infrared coatings have good performance and great market potential, due to their high production cost and complex production process, the practical application of infrared coatings is limited to a certain extent. Most of the existing infrared coatings are prepar...
