Fiber light concrete heat preservation plate with six surfaces coated with composite core material and production method of fiber light concrete heat preservation plate

The invention discloses a fiber light concrete six-surface coating composite core material heat preservation plate which comprises a first heat preservation structure layer, a second heat preservation structure layer and a concrete structure layer, and is provided with the first heat preservation structure layer made of a rock wool board and the second heat preservation structure layer made of an extruded polystyrene board at the same time. Meanwhile, the excellent fireproof performance and the heat preservation effect of the heat preservation plate are guaranteed, the first heat preservation structural layer and the second heat preservation structural layer are connected through nail connecting pieces, the concrete structural layer is used for coating, contact between heat preservation materials and air open fire is isolated, limitation on heat expansion of core materials is enhanced, wall face cracking caused by uneven deformation is prevented, and the heat preservation effect is good. The volume stability
