Procedures for the manufacture of a moulding body, in particular for the construction or furniture industry

摘要

The method of producing a molded body (50) for construction or furniture industry, comprises mixing a mixture of mineral- or wood fibers, wood flour and/or wood-chips with a bonding agent such as synthetic resin and converting to a molding material by drying at 50[deg] C, where the molding material after drying contains a humidity content of 7-10 wt.%, and forming the molded body from the molding material at 100-200[deg] C. The mold body has a residual moisture of less than 5 wt.%. The bonding agent comprises acrylic, copolymer, styrene or water.

The mold body has a residual moisture of less than 5 wt.%. The molding material is filled in a pressing tool and is pressed with a pre-determined temperature for 1 minute with a pressure of 20-50 bar. The mixture comprises mineral- or wood fibers, wood flour and/or wood-chips. The bonding agent comprises acrylic, copolymer, styrene or water. The molding material before drying comprises: wood fibers (25-50%), mineral fibers (0-25%) and bonding agent (50-65%); wood chips (50-65%), wood flour (0-10) and bonding agent (30-50%); or mineral fibers (35-50%), graphite and/or mica (0-15%) and bonding agent (50-65%). An independent claim is included for a molding material for producing a molded body.
