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;

Abstract

The invention discloses a preparation method of outer wall temperature-change-resisting antioxidant color coating for a factory. The coating prepared by the preparation method comprises the following components in percentage by weight: 40-50% of polymer emulsion of styrene-acrylic acid copolymer, 5-8% of PbMoO4 pigment, 10-15% of phase-change paraffin wax micro capsule, 6-8% of cobalt blue, 1-2% of dispersing agent, 10-20% of flake-shaped aluminite powder, 0.5-1% of thickening agent, 1-2% of anti-ultraviolet additive and the rest of water. The outer wall temperature-change-resisting antioxidant color coating prepared by the preparation method has wide application range, is antiseptic and anticorrosive, can be used under a certain temperature, has low cost, and is suitable to be applied in different regions.

Description

technical field [0001] The invention relates to a method for preparing paint, in particular to a method for preparing a temperature-resistant and anti-oxidation color paint for factory exterior walls. Background technique [0002] With the development of the national economy and high technology, the demand for special coatings is increasingly urgent in addition to general-purpose coatings. Among anti-corrosion coatings, peroxide ethylene coatings, epoxy resin coatings, and oxysulfonated polyethylene coatings all exist concurrently, but each has its own shortcomings. Ethylene peroxide paint came out in the early 1970s. This kind of paint has a certain anti-corrosion effect, but due to the large molecular weight, the leveling property is not ideal, the solid content is low, generally only 14-18%, the paint film density is poor, and the viscosity is also very high. Low, only 20-50 seconds, its adhesion is not good, and the paint film is easy to fall off. [0003] Among many f...
