Description
Technical Field

Background
Compared with the traditional noctilucent material, the paint with the long afterglow photoluminescence ceramic powder, namely the energy storage luminous paint, can absorb the energy of light sources such as sunlight and light in advance and store the energy, and after the light sources disappear, the paint can emit light in the dark to provide brightness for the environment, and the continuous luminous time reaches more than 10 hours. The paint is widely applied to the industries of daily home decoration, constructional engineering and the like at present, and is used as hidden lighting and low-degree emergency lighting, so that great convenience is brought to night life of people. By zhangwei (preparation and research of water-based interior wall luminescent paint, modern paint and coating, 2008, (2): 15-17, 23) in 2008, a preparation method of interior wall energy storage luminescent paint using styrene-acrylic emulsion and deionized water as dispersion media and rare earth metal aluminate as luminescent material is reported, and the continuous luminescence time reaches 6 h. The application of the energy-storage luminescent coating in tunnel lighting is introduced in Feng gezhong (research on energy-storage luminescent multifunctional coating auxiliary tunnel lighting test, modern tunnel technology, 2016, 53 (4): 189-.
In recent years, as an advanced environment-friendly functional material, the anion paint gradually moves to the life of people. The negative ions in the air are OH- (H2O) n, O2- (H2O) n and CO4- (H2O) n, and the negative ions with proper concentration in the air have very beneficial effects on the health, the long life and the ecological environment of human beings, so the negative ion coating can be widely applied to the coating of environments such as families, schools, hospitals, high-grade apartments, food and drink operation rooms and the like. Li Tong Xin (functional coating for releasing negative ions, novel building material 2006, (5): 34-35) introduces a preparation method of negative ion interior wall coating, and detection results show that the coating can release a large amount of negative ions and far infrared rays, remove indoor harmful substances and purify air.
In some semi-closed or totally closed and humid places, such as tunnels, basements, cabins and the like, the air circulation is not smooth, the quality is poor, suspended dust and toxic and harmful gas exist in the air, bacteria, molds and the like are easy to breed, and the places have the requirements on low-cost illumination and environmental purification. The composite type interior wall coating integrating energy storage, luminescence and anion release can simultaneously meet the requirements, but no products of the type are disclosed at present, so research and development are urgently needed to meet the market demand.
