A kind of multifunctional paint for building wall decoration

Abstract

The invention discloses a multifunctional coating for building wall decoration. A special long afterglow luminescence anion material which is obtained by mixing and ball-milling strontium carbonate, europium oxide, dysprosium oxide, boron oxide, aluminum oxide with at least one of ammonium dihydrogen phosphate, tourmaline, medical stone or diatom ooze, burning the mixture under the protection of H2 / N2 atmosphere, and then carrying out crushing, surface treatment and baking; the special long afterglow luminescence anion material is added to a conventional building coating, so that the multifunctional coating has the characteristics of the conventional building coating, also has the functions of saving energy, reducing consumption, brightening, delaying luminescence, safely preventing disasters and improving air quality, is in favor of escape and fire extinguishment in the case of a fire accident in specific environments of a highway tunnel, a railway tunnel, a rail transit project, underground comprehensive utility tunnel engineering, municipal underground engineering, military and civil defense engineering, and public places of underground stores, stations and schools.

Description

technical field [0001] The invention relates to a multifunctional coating for building wall decoration, which is specifically applied in the field of interior and exterior wall decoration of building structures, and can be widely used in road tunnels, railway tunnels, rail transit projects, underground comprehensive pipe gallery projects, municipal underground passage projects, Military and civil defense projects, as well as underground shopping malls, stations, docks, schools and other public places. Background technique [0002] Ventilation and lighting are two major aspects of energy consumption in building structures. The purpose of ventilation is to use fresh air to dilute and remove harmful gases and dust particles in the building to improve air quality. Ventilation and energy-saving measures often focus on the control of the ventilation system, and lighting energy-saving measures are mainly to arrange energy-saving lamps and optimize the layout of lamps. However, th...

Problems solved by technology

Various studies have shown that when people are escaping after a fire, it is difficult for people to escape effectively when the visual distance of the eyes is less than 3 meters in the state of smoke.

In addition, a fire will often cause a short circuit of the cable and a power outage. Conventional building wall decoration paints have no effect on guiding escape in the dark and thick smoke.

Emergency lighting fixtures play a very limited role in indicating because of their discontinuous illumination
