FIELD: process engineering.
SUBSTANCE: invention relates to production of construction boards with wood core. Proposed method comprises the steps that follow. 1) Sputter of wood fibers or ships coated with glue to make chipboard. 2) Compaction of said chipboard at high temperature to make large-size board with shagreen layer at, at least, its top surface. 3) Application of primer of melamine-based liquid resin on board surface to be coated. Note here that said resin penetrates, at least partially, into board surface layer to impregnate said shagreen and improve its properties. 4) Primer draying and 5) application of primer on the pad. 6) Primer drying and 7) application of at least one varnish saturated with painting water-based pigments to create the pattern. 8) Pattern drying and 9) application of sealing layer saturated with wear-resistant particles and resin cellulose melamine-based fibres. 10) Sealing drying and 11) application of liquid resin pad on board bottom layer. Note here that said resin penetrates, at least partially, into board bottom surface layer. 12) Pad drying and 13) application of stabilizing layer on said bottom surface. 14) Compaction of sandwiched structure by high temperature and pressure and 15) separation to panels of required width and length. 16) Application of bonding means and fixing elements on opposite lateral edges for flue-free joint and fixation of several panels to the floor floating structure.
EFFECT: wear-resistant laminar panels.
