Energy-storage luminescent coating, reflective fabric and preparation process

Abstract

The present invention discloses an energy-storage luminescent coating, a reflective fabric and a preparation process. The coating comprises the following raw materials in percentage by mass: 40 to 60percent of inorganic adhesive, 5 to 10 percent of reflective powder, 2 to 4 percent of red fluorescent powder, 2 to 4 percent of green fluorescent powder, 2 to 4 percent of blue fluorescent powder, 0.02 to 0.1 percent of fluorescent whitening agent, 0.1 to 0.3 percent of brightening agent, 0.01 to 0.05 percent of yellowing transparent agent, 0.1 to 0.5 percent of ultraviolet absorbent, 0.5 to 3 percent of dispersing agent, 0.2 to 1.5 percent of defoaming agent, 10 to 20 percent of TiO2 powder, and the balanced being water. The reflective fabric adopts the coating as a reflective layer and combines the refraction effect of calcite, so that the reflective fabric can achieve 97% total reflectance and 94% diffuse reflectance; in addition, fillers such as glass beads and ceramic beads are not added into the components, so that the heat transfer effects of all parts in the coating are the same and the heat preservation effect is good, and all parts of the reflective fabric are heated consistently; therefore, the problem that a local coating falls off due to temperature gradient is avoided.

Description

technical field [0001] The invention relates to the field of tunnel light environment, in particular to a high diffuse reflection energy storage reflective cloth used in tunnels, and an energy storage luminescent material and a preparation process used in the reflective cloth. Background technique [0002] Tunnels are engineering buildings buried in the ground and are a form of human use of underground space. Tunnels can be divided into highway tunnels, submarine tunnels, railway tunnels, underpasses, underground parking lots, and civil air defense projects. In recent years, with the vigorous development of my country's transportation industry, the number of tunnels built has increased year by year. [0003] As the number of tunnels is increasing year by year, in order to ensure the safety and comfort of tunnel operation, the quality of tunnel light environment is getting more and more attention. According to the general technical requirements of tunnel design and construct...

AI Technical Summary

Problems solved by technology

In the prior art, glass beads are directly added as fillers in energy-storage luminescent coatings, although the reflective performance and diffuse reflection effect of the coating can be improved to a certain extent, but the thermal insulation effect of glass beads is poor, and the unevenly distributed glass beads Beads lead to poor local heat insulation effect of the coating. After a period of use, the local adhesive is more likely to fail, and the local coating will fall off, thereby reducing the overall reflective effect.
