FIELD: process engineering.
SUBSTANCE: invention relates to method of corkboard production. Proposed method comprises preparation of cork chips, their compaction to boards, heat treatment at 290-300°C and cooling down. Prior to compaction, cork chips are mixed with polyaminetriazol fibers cut to 10-70mm-long lengths. Note here that said fibers make 0.5-5% of cork fiber volume.
EFFECT: higher strength.
