Embodiment 1
[0028] The paint components are as follows:
[0029] Polymer emulsion of styrene-acrylic copolymer 50%,
[0030] Flake aluminum powder 10%,
[0031] PbO 4 Pigment 5%,
[0032] Phase Change Paraffin Microcapsules 15%
[0033] Cobalt Blue 6%,
[0034] Dispersant 2%,
[0035] Thickener 0.5%,
[0036] Anti-UV additives 2%
[0037] The balance is water.
[0038] Its preparation method comprises the following steps:
[0039] 1) Add cobalt blue and dispersant to the polymer emulsion, and when heated to 42.5°C by infrared radiation, turn on the ultrasonic wave, so that the cobalt blue can be microcosmically linked with the emulsion. The ultrasonic power is 920W, the frequency is 650Hz, and the ultrasonic wave is 32min;
[0040] 2) Add flake aluminum powder, PbMoO 4 Pigment, phase-change paraffin microcapsules, stirred under mechanical stirring for 35min, stirring speed 150r / min;
[0041] 3) Add thickener and anti-ultraviolet additive, stir mechanically for 5min; speed 200r / ...
Embodiment 2
[0046] The paint components are as follows:
[0047] Polymer emulsion of styrene-acrylic copolymer 45%,
[0048] Flake aluminum powder 15%,
[0049] PbO 4 Pigment 7%,
[0050] Phase Change Paraffin Microcapsules 13%
[0051] Cobalt Blue 8%,
[0052] Dispersant 1%,
[0053] Thickener 1%,
[0054] Anti-UV Additive 1%
[0055] The balance is water.
[0056] Its preparation method comprises the following steps:
[0057] 1) Add cobalt blue and dispersant to the polymer emulsion, and when heated to 37.5°C by infrared radiation, turn on ultrasonic ultrasound, so that cobalt blue can be microcosmically linked with the emulsion. The ultrasonic power is 830-920W and the frequency is 650Hz. 32min;
[0058] 2) Add flake aluminum powder, PbMoO 4 Pigment, phase-change paraffin microcapsules, stirred under mechanical stirring for 20-35min, stirring speed 100r / min;
[0059] 3) Add thickener and anti-ultraviolet additive, stir mechanically for 5 minutes; speed 150r / min;
