Embodiment 1

[0023] Continuous phase (white): Add 35 parts of water and 0.5 parts of hydroxyethyl cellulose in sequence in the dispersion tank, adjust the speed to 350rpm, then increase the speed to 1000rpm, add 15 parts of infrared powder, disperse and stir for 15min, then reduce the speed Adjust to 600rpm, add 2 parts of Texanol, stir for 5 minutes, slowly add 45 parts of EVA emulsion, 2 parts of metal ion solution, 0.5 parts of antifungal agent, stir evenly and disperse for 10 minutes, then seal and store;

[0024] Dispersed phase (white): Add 27 parts of water, 0.5 parts of BR3 wetting and dispersing agent, 0.5 part of 7010 defoamer to the dispersion tank in turn, stir at 300rpm, add 20 parts of infrared powder; increase the speed to 1200rpm, disperse Stir for 15 minutes; adjust the speed to 800rpm, add 2 parts of carboxymethyl cellulose, stir for 5 minutes, then slowly add 50 parts of EVA emulsion, stir well and set aside;

[0025] Dispersed phase (black): Add 39 parts of water, 0.5 p...

Embodiment 2

[0029] The dispersed phase (white) and the dispersed phase (black) are prepared by the method of Example 1, and the dispersed phase (red) only needs to replace silicon carbide and graphene with iron oxide and zirconia; the continuous phase (white) also adopts Example 1 prepared by the method;

[0030] Finished product: add 70 parts of continuous phase to the dispersion tank, stir at low speed, slowly add 10 parts of dispersed phase (white), 10 parts of dispersed phase (black), and 10 parts of dispersed phase (red) until the particle diameter reaches the requirement That's it.

Embodiment 3

[0032] Dispersed phase (white), dispersed phase (black) and dispersed phase (gray) are prepared by the method of Example 1, the continuous phase (white) only needs to replace the infrared powder with silicon carbide, and the carbon fiber tube filler adopts the method of Example 1 preparation;

[0033] Finished product: Add 80 parts of the continuous phase to the dispersion tank, stir at low speed, slowly add 5 parts of the dispersed phase (white), 10 parts of the dispersed phase (black), and 5 parts of the dispersed phase (gray) until the particle diameter reaches the requirement That's it. The general performance test of the coating in the above examples, the emissivity is tested according to GJB2502.3-2006, and the specific results are shown in Table 1:

[0034]

[0035]

[0036] It can be seen from the above table that the water-based heat-radiating multi-color paint of the present invention has high water resistance, high humidity and heat resistance, beautiful surf...

Abstract

The invention discloses water-based color paint having the function of heat radiation. The paint comprises 10-40 parts of disperse phase and 60-90 parts of continuous phase. The heat radiation is imparted to the water-based color paint, so that the paint can have the functions of decorating, heat radiating and cooling; the paint is applicable to blade coating, brush coating and spray coating with special guns, and is also applicable to industrial insulation inner surfaces and building exterior surfaces.

Description

technical field [0001] The invention relates to the field of functional architectural coatings, and relates to a preparation method and application of a decorative functional coating integrating water-based, colorful and heat radiation functions. Background technique [0002] Water-based colorful paint can form natural marble patterns and color decorative patterns after construction. Compared with ordinary paints, it has excellent painting characteristics and integrates decorative performance and functionality. Compared with natural stone, it has the characteristics of light weight, safer and more environmentally friendly, creative and adaptable. [0003] The basic principle of heat radiation: heat transfer is carried out in three ways: conduction, convection and radiation. Thermal radiation is optically characterized as absorptivity, emissivity, and reflectivity. Among them, the emissivity is divided into hemispherical emissivity and normal emissivity. In order to obtain ...
