Abstract
The present disclosure discloses a modified calcium silicate board, and belongs to the technical field of floors and decorative boards. A modification method comprises steps of: dipping a calcium silicate board in a silicon dioxide solution with a solid content of 95% or more, completely absorbing the silicon dioxide solution until the calcium silicate board is saturated, and drying the dipped calcium silicate board; and carrying out sizing hardening on any surface of the modified calcium silicate board to obtain the calcium silicate board, so as to enable the triamine impregnated paper to be directly laminated with the calcium silicate board in a hot-pressing manner, and enable the surface bonding strength to reach 1 MPa; wood veneers, fireproof plates and other materials are subjected to coldbonding, the peeling strength of the product meets the requirements, and the practicability of the calcium silicate board is effectively improved.
