The invention discloses a
polyurethane composite-type waterproof thermal-insulation decorative board and a production method of the board. The board is the composite board formed by thermal-
insulation layer material comprising expanded
perlite of inorganic ore material, hollow glass beads,
coal ash and serozem, binder comprising high-strength foaming
polyurethane, and decorative panel comprising marble,
ceramic tile and
calcium silicate board with microporous. The production method comprises the following steps: arranging inorganic thermal-insulation material and
polyurethane binder
raw material into a container according to the proportion, wherein the container is provided with a stirrer, stirring continuously in order to enable the inorganic thermal-insulation material to fully contact the polyurethane, flowing the mixture directly to the back surface of the decorative panel from a
discharge, foaming, curing, and molding into a board,
cutting and packaging, thereby obtaining the product. The board is low in volume weight, low in coefficient of
thermal conductivity, high in compression strength, is fireproof, so that the board is an ideal outer wall thermal-insulation decorative material.
