The invention discloses a novel light-weight plate material. The novel light-weight plate material comprises the following raw materials in parts by weight: 6 to 13 parts of coal ash, 15 to 30 parts of cement, 12 to 18 parts of broken glass, 11 to 17 parts of waste tires, 7 to 14 parts of oil shale, 5 to 20 parts of diatomite, 6 to 15 parts of epoxy resin, 3 to 5 parts of hydroxymethyl cellulose, 5 to 10 parts of perlite, 10 to 20 parts of polyurethane particles, 7 to 11 parts of wood shavings, 5 to 13 parts of plant straw, 3 to 9 parts of calcium stearate, 1 to 3 parts of an anti-foaming agent, 1 to 2 parts of an early strength agent, 0.8 to 1.5 parts of a water repellent and 1.3 to 1.8 parts of a reducing agent. The novel light-weight plate material has the properties of energy conservation, fire resistance, sound insulation, light weight and the like, solves the problems about large beams, large posts and deep foundations, has a good anti-seismic property because of frame connection, is suitable for low-rise buildings, and is also suitable for high-rise buildings and the buildings, such as soft foundations, sands and beaches.
