METHOD FOR PRESSING CONSTRUCTION PRODUCTS FROM WOOD-POLYMER COMPOSITE MATERIAL Russian patent published in 1995 - IPC

Abstract RU 2041060 C1

FIELD: production of wood-polymer composite materials. SUBSTANCE: method involves subjecting heated wood particles mixed with binder to shear deformation till molding process is initiated; with wood particles with the size of 80-500 micron being used to be mixed and with amount of wood particles ranging from 80 to 90% and polyolefine wastes in an amount of 20-10% flattening wood particles at 150-180 C by passing them between rotating rolls, to provide compression of wood particles at a pressure of 25-50 kg/cm2. Space between rolls is within the range of 40-100 microns. EFFECT: increased efficiency and high quality of construction products. 1 dwg, 1 tbl
