METHOD OF OBTAINING WOOD END PANELS Russian patent published in 2009 - IPC B27M3/04 

FIELD: construction.

SUBSTANCE: invention concerns production of decking panels out of wood end bricks for interior floor and wall finishing. Method allows for obtaining finished panels out of wood end bricks with elastic insulation interlayer based on polymer composition consisting of high-grade natural rubber - 59.25-60.32%, zinc white - 3.03-5.02%, titanium white - 4.50-6.06%, phthalic anhydride - 0.61-1.00%, stearine - 0.03-0.20%, chalk - 24.20-24.54%, paraffin - 1.22-2.4%, technical sulphur - 1.80-1.85%, diphenylguanidine - 0.30-0.32%, tetramethylthiuram disulfide - 1.21-2.00, pigment orange G - 0.20-0.30%, pigment yellow K - 0.06-0.07%. Composition is rolled in sheet form, wood blanks are made in the form of 5-50 mm thick bricks or bars. Wood blanks are placed in bottomless mould covered by polymer composition sheet, wrap polymer composition sheet at one side of mold and wood end bricks at the other side in cotton fabric for moisture absorption and prevention of adhesion between polymer composition and heated press slab. Press slabs are closed, and panel for floor and wall finishing is formed by curing polymer composition comprising panel base after curing at 145-185°C and pressure of 3-12.5 MPa (30-125 kgs/cm²).

EFFECT: obtaining panels out of wood end bricks for floor or wall decking with improved physical and mechanical properties.
