#CMT# #/CMT# A wooden composite material comprises facing sheet (A) having single layer (a) made from timber and/or timber materials, facing sheet (B) having single layer (b) made from timber and/or timber material, intermediate portion having inner middle layer made from timber and/or timber materials and/or organic materials. The composite material is formed by impregnating facing sheets (A) and (B) with solution from furfuryl alcohol and anhydrides of organic acid, soaking intermediate portion with furfuryl alcohol and anhydrides of organic acid or its precondensates, and plasticizing. #CMT# : #/CMT# A wooden composite material comprises facing sheet (A) having single layer (a) made from timber and/or timber materials, facing sheet (B) having single layer (b) made from timber and/or timber material, intermediate portion having inner middle layer made from timber and/or timber materials and/or different organic Materials, provided between facing sheets (A) and (B). The composite material is formed by impregnating facing sheets (A) and (B) with solution from furfuryl alcohol and anhydrides of organic acid, soaking intermediate portion with furfuryl alcohol and anhydrides of organic acid or its precondensates, and plasticizing at predetermined temperature, pressure and time. An independent claim is included for manufacture of wooden composite material. #CMT#USE : #/CMT# Wooden composite material is used as lightweight construction board for building (all claimed). #CMT#ADVANTAGE : #/CMT# The wooden composite material is manufactured efficiently and economically with excellent dimensional stability and mechanical/dynamic characteristics. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Composition: The intermediate portion is soaked with precondensate from furfuryl alcohol. |
