Problems solved by technology

[0003] However, in practical applications, due to the special environment of the tunnel: semi-closed and humid, the coating is greatly affected by the environment, which leads to a decline in the performance of the coating. The afterglow brightness of the marking lines and marking patterns coated with luminous coatings decays quickly. short life

Abstract

The invention discloses a self-luminous coating for a tunnel. The self-luminous coating is prepared from the following components in parts by weight: 10 to 20 parts of resin emulsion, 15 to 30 parts of glass beads, 20 to 30 parts of cement, 3 to 8 parts of nano-scale rare earth luminescent material, 1 to 3 parts of mixture of graphene and expanded graphite, 0.5 to 2 parts of K resin and 0.1 to 1 part of polyethylene resin, wherein the nano-scale rare earth luminescent material is a nanosheet, a nanowire or a nanorod. The self-luminous coating disclosed by the invention has the advantages of high after-glow brightness, long duration time under the dark condition and lower attenuation speed; a marking produced by using the self-luminous coating is high in inductivity.

Description

technical field [0001] The invention relates to a luminous coating, in particular to a tunnel self-luminous marking line and the coating. Background technique [0002] Self-luminous materials are also called ultra-long afterglow energy storage luminescent materials, which can excite invisible light waves into visible light waves after being irradiated by light, store excess light energy, and store the stored light energy after stopping the light. Released slowly in the form of fluorescence, this material has a good inductive effect on escape and rescue, so it is widely used in highway tunnels and underground traffic projects. [0003] However, in practical applications, due to the special environment of the tunnel: semi-closed and humid, the coating is greatly affected by the environment, which leads to a decline in the performance of the coating. The afterglow brightness of the marking lines and marking patterns coated with luminous coatings decays quickly. Short life. C...
