METHOD FOR MANUFACTURE OF PLATES FROM SUNFLOWER HUSK Russian patent published in 2005 - IPC

FIELD: production of plate materials of the splint-slab type, applicable in the wood-working and building industries.

SUBSTANCE: the method consists in processing of husk particles by a binder containing urea-formaldehyde resin, ammonium chloride, Aerosil butadienstyrene methacrylic latex, forming of the mat, cold prepressing and hot pressing. The binder instead of ammonium chloride contains ammonium fluosilicate at the following relation of the components, mass percentage: urea-formaldehyde resin - 82.8 to 93.4, ammonium fluosilicate - 0.6 to 1.2; butadienstyrene methacrylic latex - 4.0 to 12.0, Aerosil - 2.0 to 4.0.

EFFECT: enhanced physico-mechanical characteristics of the plates.
