METHOD OF PRODUCTION OF THE PLATES FROM COMPOUND MATERIALS Russian patent published in 2012 - IPC B27N3/02 

FIELD: construction materials production.

SUBSTANCE: invention relates to the production of the construction materials from waists of the wood processing industry; the method comprises filler fractionating and filler processing by the water solution of copolymer vinylcyclohexene with maleic anhydride followed by drying, adjustment of the modified wooden particles with polyethylene by means of mixing and heating followed by rolling on the laboratory rollers with the roller diameter of 180 mm and gapping between them of 1 mm, pressing of the received mass in the press-mould of the hydraulic pressing unit with the mark of origin ПГ-60 at the temperature of 180-210°C and pressure of MPa; the wood-polymer composites (WPC) is induced as an ingredient increasing the mechanical and physical characteristics of the compound and resistibility to UV irradiation, and thereafter the secondary polyethyleneterephthalate in the following proportions (%, mass): secondary polyethylen: 20.0-50.0; secondary polyethyleneterephthalate: 35.0-20.0; wooden particles: 37.5-22.5; CVMA: 2.5-7.5.

EFFECT: implementation of this method allows to increase physical, mechanical and ecological characteristics of the WPC plates.
