Problems solved by technology

But they all have shortcomings. Quartz polyurethane and protective film increase the cost, and the process operation is complicated, which is not conducive to on-site operation, and the properties of luminescent materials also affect the luminous properties and cost of concrete.

Abstract

The invention relates to light-emitting concrete, particularly a preparation method of energy-storage light-emitting concrete. The energy-storage light-emitting concrete is prepared from the following raw materials in percentage by weight: 2-8% of fluorescent powder, 18% of white cement, 27% of standard sand, 39-47% of gravel and 8% of water. The CaO:Dy3+,Na+ fluorescent powder is prepared from initial raw materials CaCO3 (analytically pure), Na2CO3 (analytically pure) and Dy2O3 (99.99%, analytically pure) in a Ca:Dy:Na mol ratio of l:x:y, and a small amount of ethanol is added as a grinding aid. The prepared CaO:Dy3+,Na+ fluorescent powder has the advantages of no pollution, no radiation, favorable light-emitting performance and simple production technique, and has the meanings in environmental protection and energy saving. The prepared light-emitting concrete has the advantages of long light-emitting time and no radioactivity; and after being irradiated under sunlight in the day time or under a common daylight lamp for 50 minutes, the light-emitting concrete can continuously emit light in a dark place for more than 6 hours.

Description

technical field [0001] The invention relates to a luminescent concrete, in particular to a luminescent concrete which absorbs sunlight or ultraviolet light during the day, stores light energy, and releases the stored light energy in the form of visible light at night and a preparation method thereof. Background technique [0002] Long afterglow luminescent material is a new type of functional material that absorbs sunlight or ultraviolet light during the day, stores the light energy, and releases the stored light energy in the form of visible light at night when the light stops shining. Long afterglow materials themselves cannot be directly used as end products, and must be combined with other materials to be applied. Concrete is the most commonly used material in the construction industry, and it is widely used in the construction of some public facilities. Therefore, the development and innovation research of concrete is quite important. important and has a bright future. ...
