Embodiment 1

[0033] Coating production method:

[0034] Weigh the following components according to weight fraction: 180 parts of polystyrene hollow microspheres, 90 parts of aluminum silicate, 125 parts of kaolin, 5 parts of thickener, 2 parts of defoamer, 5 parts of dispersant, 35 parts of ethylene glycol Parts, 4 parts of polyoxypropylene wetting agent, 500 parts of pure acrylic emulsion, 120 parts of water. The paint also contains 5 parts of triethylamine pH regulator and 2 parts of preservative. Add water, thickener, defoamer, dispersant, ethylene glycol, sodium hydroxide pH regulator and preservative to the mixer, and stir until uniform at 1500rpm; add pure acrylic emulsion, and stir at 1800rpm until uniform; Add polystyrene hollow microspheres, aluminum silicate and kaolin, stir at 800 rpm until uniform; sieve through a 165-mesh sieve.

[0035] After testing, its tensile strength is greater than 1MPa, its solar reflectance is greater than 0.8, and its thermal conductivity is great...

Abstract

The invention relates to a paint and a preparation method, the paint comprises the following raw materials by weight part: 100-200 parts of polystyrene hollow microballoons, 30-125 parts of alumina silicate, 30-135 parts of kaolin, 2-5 parts of thickening agent, 1-10 parts of antifoaming agent, 1-10 parts of dispersant, 8-38 parts of glycol, 3-10 parts of wetting agent, 180-550 parts of emulsion paint emulsion and 100-350 parts of water. The paint of the invention is composed of polystyrene hollow microballoons suspended in an inert latex, a microstructure of the microballoons is in favor of reflection and diffraction of the infrared ray, in addition, the microballoons of the present invention are enclosed hollow balls with low heat conduction coefficient, and are added in the paint to form a plurality of the isolated heat insulation cavities, so that heat insulation performance is substantially raised.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a heat-insulating coating for building surfaces and a preparation method thereof. Background technique [0002] At present, the existing building wall insulation coatings in my country are usually based on increasing the gas phase void ratio, reducing the thermal conductivity and conducting heat transfer, such as fiber insulation materials and profile insulation materials. Profile-type inorganic thermal insulation materials need to be assembled and constructed, and have disadvantages such as many seams, affecting the appearance, poor waterproof performance, and short service life. Coating, and the heat insulation effect is not good. Contents of the invention [0003] The invention designs a paint and a preparation method thereof, and aims to provide a paint with high-efficiency heat insulation function, environmental protection and pollution-free. [0004] In order to achieve the abo...
