WOOD-PARTICLE COMPOSITE MATERIAL AND METHOD FOR ITS MANUFACTURING Russian patent published in 2010 - IPC B27N3/02 

FIELD: wood working industry.

SUBSTANCE: invention relates to the field of production of wood-particle composite materials and relates to wood-particle composite material and method of its manufacturing. Material contains pressed wood-particle filler and binder, material has monolithic low-porosity structure characterized by achieved density of up to 2 g/cm³, thickness of chips makes from 0.1 to 1.0 mm, pores of wood-particle filler are fully filled with binder, such as wood resinous substances that are released from chip filler in process of its hot pressing as composite material is made. Method of manufacturing consists in the fact that filler is pressed as wood chips in presence of binder, at the same time binder is used, which is released from chips as it is pressed with pressure of 2-5 MPa, besides puncheon and die of press are pre-heated to temperature of 220-300°C, and process of hot pressing is carried out in cyclic loading mode.

EFFECT: invention makes it possible to increase efficiency of wood-particle composite material manufacturing method and to improve quality, due to increased strength, water resistance and fire resistance of manufactured wood-particle composite materials.
