一、前言 黑荆树自然分布于澳大利亚东南部和塔斯马尼亚岛。它是一种速生、伐期短、单宁含量高的多用途树种。黑荆树单宁的主要组分为多类黄酮(C-C-C化合物),它与甲醛的缩合反应物是黑荆树单宁胶粘利的基础。目前,单宁胶粘剂广泛用于刨花板、胶合板和其他木制品工业。 50年代,我国南方开始引种黑荆树。种子产地不清,多数进口种子来源于非原产地国家 I. Introduction Black Wattle naturally distributed in southeastern Australia and Tasmania. It is a fast-growing, short-cut, multi-purpose species with high tannin content. The main component of black wattle tannin is a variety of flavonoids (C-C-C compounds), its condensation reaction with formaldehyde is the basis for black currant tannin adhesive. At present, tannin adhesives are widely used in particle board, plywood and other wood products industries. 50’s, South China began to introduce black wattle.
