Example Embodiment
[0044] Example 1 Highly reflective, high-emission thermal insulation coating
[0045] High reflection, high emission heat insulation coating formula
[0046] Component content / g Component content / g
[0047] Deionized water 20-30 Dispersant 2
[0048] Rutile Titanium Dioxide 10-12 Defoamer 1
[0049] Superfine aluminum silicate 5-10 anti-mold fungicide 0.1
[0050] Far infrared ceramic powder 10-13 Thickener 1.5
[0051] Silicone acrylic emulsion 25-35 film forming aid 1.5
[0052] It has been determined that the visible light reflectivity is 95%, the full-wavelength reflectivity is 86.5%, the emissivity of 3-5μm is 0.93, and the emissivity of 8-13.5 is 0.94%. 5 cycles, the stain resistance rate is 10%.
[0053] The above-prepared reflective surface coating and thermal insulation primer are combined to form a coating system, the outer surface temperature is reduced by 17°C, and the backside temperature is reduced by 11°C.
