Embodiment 1

[0016] Example 1: 20g of heptadecafluorodecyltriethoxysilane, 100g of methyltriethoxysilane, 100g of perhydropolysilazane, 150g of solid micro and nano Particles, with a mass of 630g xylene, were mixed with an ultrasonic disperser for 30 minutes to form a superhydrophobic self-cleaning coating for buildings.

Embodiment 2

[0017] Embodiment 2: From the quality of 100g heptadecafluorodecyltriethoxysilane, the quality of 100g of methyltriethoxysilane, the quality of 100g of perhydropolysilazane, the quality of 150g of solid micro, nano Particles, the mass is 550g xylene and mixed with an ultrasonic disperser for 30 minutes, which is the architectural super-hydrophobic self-cleaning coating.

Embodiment 3

[0018] Example 3: 100g of heptadecafluorodecyltriethoxysilane, 10g of methyltriethoxysilane, 100g of perhydropolysilazane, 150g of solid micro and nano Particles, with a mass of 640g xylene, were mixed with an ultrasonic disperser for 30 minutes to form a superhydrophobic self-cleaning coating for buildings.

Abstract

The invention relates to a super-hydrophobic self-cleaning coating for a building. The coating is prepared by dispersing and mixing 2-10% by mass of heptafluorodecyl triethoxysilane, 1-10% by mass ofmethyl triethoxysilane, 1-10% by mass of perhydropolysilazane, 2-15% by mass of solid microparticles and the balance a solvent. The super-hydrophobic self-cleaning coating for the building has the advantages that the super-hydrophobic self-cleaning coating is stable in super-hydrophobic property and unlikely to age and lose effect, and can work normally in severe working conditions such as acid, alkali, high temperature and strong ultraviolet rays; and the super-hydrophobic self-cleaning coating can be cured at a constant temperature, is not high in construction condition and is suitable for various buildings.

Description

technical field [0001] The invention relates to a super-hydrophobic self-cleaning coating for buildings. The super-hydrophobic self-cleaning coating can be formed by curing at normal temperature after being coated with the super-hydrophobic self-cleaning coating on the surface of buildings. Background technique [0002] Wettability is an important property of a solid surface, and is generally characterized by the contact angle between a droplet and a solid surface. When the contact angle between a water droplet and a solid surface is greater than 150°, the solid surface is called a superhydrophobic surface. For example, the leaf surfaces of various plants represented by lotus leaves, the feathers of water birds, etc. Superhydrophobic materials have many unique surface properties, such as self-cleaning, superhydrophobicity, etc., so they have broad application prospects in production and life, such as self-cleaning building surfaces. [0003] In recent years, superhydrophob...
