Embodiment 1

[0032] Dispersed phase (white): Add 32.4 parts of water, 0.1 part of sodium pyrophosphate, 2.0 parts of lithium magnesium silicate, 0.2 parts of dispersant, and 0.3 parts of defoamer to the dispersion tank in turn, stir at 500 rpm, and add each component disperse and stir for 3 minutes; increase the speed to 1200rpm, add 16 parts of pigments and fillers and 0 parts of heat-insulating pigments, and disperse for 15 minutes; adjust the speed to 600rpm, add 3 parts of film-forming aids, and slowly add 46 parts of silicon acrylic after stirring for 5 minutes Emulsion, stir well and set aside;

[0033] Dispersed phase (black): Add 26 parts of water, 0.1 part of sodium pyrophosphate, 2.2 parts of lithium magnesium silicate, 0.4 parts of lithium magnesium silicate, and 0.3 parts of defoamer to the dispersion tank in turn, and stir at 600 rpm. The components were dispersed and stirred for 3 minutes; the speed was increased to 1500 rpm, 13 parts of pigments and fillers and 5 parts of bl...

Embodiment 2

[0038] Dispersed phase (white), dispersed phase (black) and dispersed phase (yellow) are prepared by the method of Example 1, only the brown heat insulating pigment is replaced by a yellow heat insulating pigment; the continuous phase is also prepared by the method of Example 1;

[0039] Finished product: Add 46 parts of the continuous phase to the dispersion tank, stir at a low speed, slowly add 4 parts of the dispersed phase (white), 2 parts of the dispersed phase (black), and 26 parts of the dispersed phase (brown) during the stirring process, until the particle diameter reaches the requirement Finally, add 18 parts of silicone acrylic emulsion, and finally add 0.2 parts of pH adjuster and 3.8 parts of thickener aqueous solution to adjust to a suitable viscosity.

Embodiment 3

[0041] Dispersed phase (blue), dispersed phase (brown) and dispersed phase (yellow) are prepared by the method of Example 1, only need to replace the brown heat insulating pigment with brown heat insulating pigment, blue heat insulating pigment and yellow heat insulating pigment ; Continuous phase also adopts the method preparation of embodiment 1;

[0042] Finished product: Add 46 parts of the continuous phase to the dispersion tank, stir at a low speed, slowly add 5 parts of the dispersed phase (blue), 21 parts of the dispersed phase (brown), and 6 parts of the dispersed phase (yellow) during the stirring process until the particle diameter reaches After request, add 20 parts of silicone acrylic emulsion, and finally add 0.2 parts of pH adjuster and 3.8 parts of thickener aqueous solution to adjust to a suitable viscosity.

Abstract

The invention discloses a water-in water type colorful thermal insulation coating which comprises the components in parts by weight: 35-50 parts of continuous phase, 30-40 parts of dispersed phase, 15-30 parts of silicone acrylic emulsion and 0.2-5.0 parts of regulator. The heat insulation performance is applied to water-based colorful coating, so that the invention integrates high-grade decoration performance and the heat insulation performance; before the water-in water type colorful thermal insulation coating is used, right amount of water is added into the coating for adjusting the viscosity, and then the coating is sprayed onto a building by a special spray gun, so that the decoration effect of natural stone can be achieved, and the water-in water type colorful thermal insulation coating has reflection heat insulation function.

Description

technical field [0001] The invention relates to a paint in the field of construction, more specifically, to a water-in-water type colorful, reflective and heat-insulating exterior wall paint and a preparation method thereof. Background technique [0002] Water-based multi-color coatings can form natural stone patterns, colors and personalized decorative patterns after construction, and have coating properties such as high crack resistance that cannot be compared with ordinary coatings. It integrates high-end decorative performance and functionality. Compared with natural stone, it is light in weight, safer and more environmentally friendly, creative and adaptable. Patent CN101967329A discloses a water-based imitation marble coating, which solves the problems of product transportation and long-term storage stability; patent CN101338149A discloses a water-based colorful coating , easy to make and simple in process. [0003] Reflective heat insulation coatings can dissipate th...
