Method of manufacturing composite materials from lignocellulose raw material

FIELD: manufacture of building materials. SUBSTANCE: invention relates to manufacturing such composite issues as building planks and furniture boards, rebuild sawn goods and shaped parts without any resin binders. Disintegrated lignocellulose material containing virtually no free sugars is steam treated under pressure at 190-260 C to release hemicellulose for the period of time from 15 s to 10 min which would be sufficient to destruction and hydrolysis of hemicellulose into free sugars and other products. Afterwards material is crushed, dried, shaped into mat, and subjected to hot compaction. EFFECT: increased strength and size stability. 1 dwg, 1 tbl 73$910с ПЧ Го РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (19) ВИ” 2 075 384 ' 13) СЛ 57 МК” В 27к 9/00 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 3871134/04, 25.03.1985 (30) Приоритет: 30.03.1984 /Р 62946/84 (46) Дата публикации: 20.03.1997 (56) Ссылки: Патент СССР М 12123186, кл.
