Environment-friendly building intelligent coating

Abstract

The invention provides an environment-friendly building intelligent coating. When the coating is applied to the building surface, an effect of inhibiting plant growth is achieved. The intelligent coating is based on a light-sensation bactericidal principle, and ultraviolet light is utilized to kill bacteria and damage growth environments of plants such as muscus and moss.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection building materials, and in particular relates to a method of intelligent coating. Background technique

[0002] During the use of the building, with the accumulation of time and the climate differences in different regions, it is easy to produce mildew and moss, which will cause the walls to fall off and seriously damage the appearance and structure of the building.

[0003] At present, environmental protection and energy-saving building materials are widely used. In the process of applying environmental protection and energy-saving materials, we should not only pay attention to their environmental protection, but also pay attention to their functionality. For example, antibacterial materials, which contain antibacterial ingredients, are different from traditional materials during use. They are safer and have good antibacterial effects. They can inhibit bryophytes, reject mildew a...

Examples

Embodiment 1

[0014] Embodiment 1: a kind of preparation method of environment-friendly intelligent coating for building, comprises the following steps:

[0015] Will Er 3+ :Y 3 Al 5 o 12 The ball mill is sufficient to obtain particles with a particle size of about 200nm, and then the powder is dispersed in the PVP aqueous solution, and ethyl orthosilicate is added, and then a small amount of hydrochloric acid is added to make TEOS in Er 3+ :Y 3 Al 5 o 12 The surface is gradually hydrolyzed. Filter the powder, wash, and dry to obtain SiO2-coated Er 3+ :Y 3 Al 5 o 12 Powder. Disperse the powder in white cement to obtain smart paint. The waterproof and bactericidal layer absorbs 488nm visible light and emits 381nm ultraviolet light.

Embodiment 2

[0017] Will Er 3+ :Y 3 Al 5 o 12 Ball milling is sufficient to obtain particles with a particle size of about 200nm, and then the powder is dispersed in PVP aqueous solution, and tetrabutyl titanate is added to make it in Er 3+ :Y 3 Al 5 o 12 The surface is gradually hydrolyzed. Filter the powder, wash, and dry to obtain TiO2-coated Er 3+ :Y 3 Al 5 o 12 Powder. Disperse the powder in white cement to obtain smart paint. The waterproof and bactericidal layer absorbs 488nm visible light and emits 381nm ultraviolet light.
