Title: (EN) Boards produced with the use of grass plant lignin and process for producing thesame
Abstract:
(EN) Boards produced by heating lignocellulosic material under elevated pressure for molding the same without resort to any adhesive. The boards contain 0.2 to 30 % by weight, based on the dry weight of the lignocellulosic material, of rice plant lignin so as to achieve excellent mechanical strengths and water resistance without evolution of harmful substances such as formaldehyde. To efficiently advance the thermosetting reaction of the lignin, the molding under elevated pressure is effected at 180 to 250 °C in the process for producing the boards.
