METHOD FOR PRODUCTION OF PLATES OF SUNFLOWER HUSK Russian patent published in 2003 - IPC

FIELD: production of plate materials of the wood-shaving type, applicable in wood-working and building industries. SUBSTANCE: the method consists in processing of husk particles by binder containing urea-formaldehyde resin, ammonium chloride and styrene-butadiene methacrylate latex, formation of the carpet, cold prepressing and hot pressing. The binder additionally contains aerosil at the following relation of components: percent by mass: urea-formaldehyde resin - 76.4 to 93.2, ammonium chloride - 0.8 to 1.6, styrene butadiene methacrylate latex - 4.0 to 12.0, aerosil - 2.0 to 10.0. EFFECT: enhanced physico- mechanical indices of plates, enhanced ecologic purity. 2 tbl
