Luminescent transparent cement-based material

Abstract

The invention relates to a luminescent transparent cement-based material which comprises the following components in parts by weight: 20-40 parts of cement, 15-30 parts of luminescent powder, 20-40 parts of reflective powder, 3-6 parts of optical fiber and 1-3 parts of additive. The invention has the advantages that after the luminescent powder is illuminated, electrons in a low energy state in Eu2+ can be transited to a high energy state due to the energy absorption of photons, and light energy is converted and stored into a crystal lattice; when no illumination exists, the electrons in the high energy state in Eu2+ are returned to the low energy state, the energy is converted into the light energy to illuminate, and the illumination time can reach more than 15 hours to achieve the purposes of energy storage and illumination; and the light irradiated on the cement-based material is reflected by utilizing the luminescent powder, the luminescent powder is utilized for energy storage and illumination, then the light reflection of the luminescent powder is amplified by utilizing the reflective powder, therefore, the luminescent performance of the cement-based material is enhanced.

Description

technical field [0001] The invention relates to a cement-based material, in particular to a luminescent and light-transmitting cement-based material. Background technique [0002] With the progress of society and the development of science and technology, people have higher and higher functional requirements for building materials. In modern buildings, people not only hope to see the beautiful scenery outside through the concrete wall, but also hope that the wall can play a role in lighting. , energy saving and decorative effects. [0003] Existing concrete is generally composed of cementitious materials, aggregates, concrete admixtures and water, etc., and cannot have both the functions of luminescence and light transmission. function and seriously hinder people's sight.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a luminescent and light-transmitting cement-based material, which can store energy and transmit light under the irradiation of sunlight or ordinary fluorescent lamps during the day, and can also emit light and transmit light at night, so as to solve the problem of existing cement-based materials. The problems of not being able to store energy and transmit light during the day, and not being able to emit light and transmit light at night, play multiple roles in lighting, energy saving and decoration
