Summary: | The invention discloses a flame-retardant polystyrene board material and a preparation method and application thereof in tunnel thermal insulation engineering, and belongs to the technical field of tunnel thermal insulation, the flame-retardant polystyrene board material comprises the following raw materials by weight: 5-15 parts of polystyrene particles, 1-5 parts of an emulsion, 20-30 parts of silicate, 0.1-1.5 parts of fibers, 0.1-1 part of a water repellent, 20-30 parts of an inorganic filler, and 10-30 parts of thermosetting resin. 2-10 parts of a resin curing agent; and 1-5 parts of water. The heat preservation device for the tunnel in the cold region is sequentially provided with a primary support sprayed concrete layer, a geotechnical cloth layer, a waterproof plate layer, a flame-retardant polystyrene plate and a secondary lining concrete layer from inside to outside. According to the invention, the flame retardant property of the polystyrene board is improved, and the polystyrene board can better pr |
