METHOD OF WOOD-PLASTIC PRODUCTION Russian patent published in 2003 - IPC

FIELD: woodworking industry; production of fiber and pressed wood-fiber boards for furniture industry. SUBSTANCE: invention presents a method of wood-fiber production. The method provides for the following process: the bottom of a mould is filled with the color polymer chips, then a layer of the saw dust and wood particles, treated with the modificator is put over it and then a hot pressing with subsequent cooling down under pressure to ambient temperature is exercised. In the capacity of the modificator they use solutions of following compositions, in mass % to the mass of wood particles: fire-proof coating "Triz" with viscosity of 8-10 cct -15, 50 % suspension of copolymer of the acrylic and methacrylic acids and 60 % an emulsion of reactive polysiloxane in the water, taken in the ratio of 20 : 1 - 15. EFFECT: increased mechanical strength, reduced water absorption of the wood-plastic. 2cl, 1 tbl
