Method for producing a veneered board
A method for producing a veneered board having a veneer and a carrier board having improved use properties includes the steps of providing a veneer and a carrier board, providing a sheet of paper impregnated with binder, the sheet of paper being arranged in a stack of materials to be pressed between an upper face of the carrier board and a lower face of the veneer, and pressing the stack of materials to be pressed. The sheet of paper is impregnated with a binder, the sheet of paper impregnated with binder is pre-dried so that it is still sticky, at least one additive is applied onto the pre-dried, still sticky binder, and the sheet of paper which is impregnated with binder and provided with an additive is dried to a residual moisture content of up to 8%.
1. A method for producing a veneered board ( 1 ), comprising a veneer ( 8 ) and a carrier board ( 2 ), said method comprising the steps of:
providing a veneer ( 8 ) and a carrier board ( 2 ),
providing a sheet of paper ( 4 ) impregnated with binder, said sheet of paper being arranged in a stack of materials to be pressed between an upper face ( 3 ) of the carrier board ( 2 ) and a lower face of the veneer ( 8 ), and
pressing the stack of materials to be pressed,
wherein
the sheet of paper ( 4 ) is impregnated with the binder,
the sheet of paper ( 4 ) impregnated with the binder is pre-dried and is sticky,
at least one additive ( 7 ) is applied onto the pre-dried, sticky binder, wherein the at least one additive is not distributed in the binder and is applied at a location on the pre-dried, sticky binder, and
the sheet of paper ( 4 ) which is impregnated with the binder and provided with the at least one additive ( 7 ) is dried to a residual moisture content of up to 8%, and wherein the at least one additive is carried through the veneer at the location during the pressing, such that the at least one additive is distributed in a targeted manner in the veneer.
2. The method according to claim 1 , wherein one of the following substances or a mixture of two or more of the following substances is used as the at least one additive ( 7 ): dye, pigment, effect pigment, flame retardant, ink, UV stabilizer, infrared absorber, agents for increasing the conductivity, antibacterial agents, hydrophobizing agents, bleaching agents, or stain.
3. The method according to claim 1 , wherein the at least one additive ( 7 ) is applied as a particulate solid or in liquid form.
4. The method according to claim 1 , wherein the at least one additive ( 7 ) is not soluble in the binder or is not homogeneously soluble in the binder.
5. The method according to claim 1 , wherein, after the sheet of paper ( 4 ) is impregnated with the binder, excess binder is removed on a lower face ( 5 ) of the sheet of paper ( 4 ), which faces the carrier board.
6. The method according to claim 1 , wherein the binder is used in a first partial amount in liquid form and in a second partial amount in solid form.
