Description

Leaf surface microstructure-imitated dust retention structure of building external wall tile

Technical Field

The utility model relates to a building material technical field especially relates to a building external wall brick stagnant dust structure of imitative blade surface micro-structure.

Background

The hazard of particle suspensions under increasingly severe atmospheric pollution is not insignificant, and it presents a great hazard to both human health and the environment. Long-term accumulation of PM10 can cause respiratory diseases, such as shortness of breath, cough, asthma, chronic bronchitis, chronic pneumonia and the like. Compared with PM10, PM2.5 is more harmful to human health. In the aspect of respiratory system, PM 2.5-10 is mainly deposited on upper respiratory systems of trachea, throat and the like, while PM2.5 can enter lower respiratory systems of human bodies such as bronchus and the like, and part of fine particles can directly enter lung and reach blood circulation system after penetrating alveoli.

Different particles absorb and reflect the sun differently, which causes local temperature change and reduces local air visibility, and affects people's daily travel and work. The appearance of haze not only reduces air visibility, but also can cause influences on various aspects such as people's trips.

With the increase of a plurality of pollution events, the harm of particle suspended matters is well known by the public, the attention of government departments and the public is continuously increased, and the haze treatment process is greatly promoted.

Plants are important components of the ecological environment, not only as producers of the ecological environment, but also as "cleaners" of the ecological environment. The remarkable dust retention capacity of plants has been recognized in the last century, and then a great deal of related research work is carried out in many countries. The research shows that: the plant has obvious interception, retention and adsorption effects on particle suspended matters in the atmosphere, and villi, rough leaves, leaf surface pores, viscous secretions and the like of the plant are effective dust-holding structures of the plant. Under the current situation that the problem of air pollution cannot be solved radically, the retention of particle suspended matters by plants becomes an effective measure for solving the problem of air pollution. In addition, static electricity has been found to have an adsorptive effect on particulate suspensions in some studies, and has now found primary utility in some air purifiers.

Nowadays, with increasingly urbanization, a large number of buildings replace the original plant communities in the human living environment construction. The building is necessary to replace plants and becomes an effective independent dust-holding individual. In the urban construction at the present stage, the building exterior wall tiles are mainly attractive, such as glazed tiles, full-body tiles, mosaic tiles and the like, and although the tiles are attractive, the 'trees' in the cities lose the retention function of suspended particles, so that the haze prevention and the atmospheric ecology restoration are not facilitated. Therefore, it is urgently needed to develop a dust retention structure of a building external wall tile with a leaf surface-imitated microstructure to solve the technical problems.

In view of this, the present invention is especially provided.
