摘要

芦苇的ＳｉＯ２含量高，使用脲醛胶（ＵＦ）难以获得良好的胶合结果。本研究采用二苯基甲烷二异氰酸酯（ＭＤＩ）胶粘剂压制芦苇刨花板，试验结果表明，当ＭＤＩ施胶量为４％和５％、刨花板的密度为０．７０ｇ／ｃｍ３时，其物理力学性能指标分别达到我国Ａ类刨花板优等品和二等品的标准要求。如果ＭＤＩ单价由现在２０．００元／ｋｇ下降到１７．３０元／ｋｇ，ＭＤＩ芦苇刨花板和ＵＦ芦苇刨花板的生产成本相同

Abstract

As reed’s SiO 2 content is high, it is difficult to glue with UF resin.4,4′ diphenylmethane diisocyanate(MDI) was used to manufacture reed particleboard in this study. The results showed that mechanical properties of the particleboard reached the requierment of high class and second class of A type particleboard standard of China GB/T 4879-92 when the resin consumption was 4% or 5% while the density of the particleboard was 0 70 g/cm 3. If the MDI price is reduced from RMB 20 yuan/kg to RMB 17 30yuan/kg,production costof the particleboard will be equal to that of particleboard bonded with urea formadehyde resin.
