Embodiment 1
[0024] A tunnel self-luminous coating, which consists of the following components in parts by weight: 10 parts of polyacrylic acid emulsion with a solid content of 40%, 19 parts of glass beads with a diameter ranging from 0.2 to 0.5 mm, of which elliptical glass beads The percentage by weight is 8%. 20 parts of alkali slag cement, 3 parts of rare earth luminescent material in the form of nanosheets, 1 part of a mixture of graphene and expanded graphite, 0.5 parts of K resin, 0.1 part of polyethylene resin,
[0025] Wherein, the weight ratio of graphene and expanded graphite in the mixture of graphene and expanded graphite is 0.2:1.
[0026] First add about 1 / 2 of the mixture of glass beads, cement, graphene and expanded graphite into the mixing kettle, then add resin emulsion, K resin and polyethylene resin in turn, stir evenly, and finally add all the remaining components while stirring Stir evenly in the reaction kettle to obtain the coating. Use the above paints for the d...
