METHOD FOR PRODUCTION OF COMPOSITE MATERIALS Russian patent published in 1997 - IPC

FIELD: chemistry of polymers; manufacturing of furniture and facing materials. SUBSTANCE: ground waste of wood working industry and of pulp and paper industry is mixed with liquid binder. Into thus prepared mixture at least 5 mass % of oxides of metals having alternating valence are added; if it is necessary then filler and/or dye and/or blowing agent are also added. Thus obtained loose mass is formed and then is affected with accelerated electrons. The latter process is accompanied with foaming mass and with its hardening. Desired materials are high-impact, acid-proof and alkali-resistant. EFFECT: improved quality of desired product. 3 cl
