A new technique-Acetal Method-has been adopted for this paper.Under the action of a catalyst,diethylmethane,the by-product of chloromycetin,and residue of refined biphenol-A are condensed into thermoplastic phenolic formal- dehyde mode resin,and organic solvent is recovered at the same time.The resin produced by this technique is characteristic of the phenolic resin.With fine wood powder and mineral and graphite powder used as packings and hexamethy- lene tetraamine as cross linking agent,the resin,as adhesive,is...

A new technique-Acetal Method-has been adopted for this paper.Under the action of a catalyst,diethylmethane,the by-product of chloromycetin,and residue of refined biphenol-A are condensed into thermoplastic phenolic formal- dehyde mode resin,and organic solvent is recovered at the same time.The resin produced by this technique is characteristic of the phenolic resin.With fine wood powder and mineral and graphite powder used as packings and hexamethy- lene tetraamine as cross linking agent,the resin,as adhesive,is used to produce phenolic moulding powder,insulating plates and graphite products;it is also substituted for synthetic aliphatic acid,making up synthetic adhesive used for casting sand cores,the tensile strength of which is twice as great as the original one.

本文采用了“缩醛法”新技术,在催化剂作用下,将合成氯霉素的付产甲醛酯(学名二氧基甲烷或乙醇缩甲醛)和精制双酚 A 的残渣缩聚成热塑性酚醛型树酯,同时回收有机溶剂。使用本技术生产的树酯,性能类似酚醛树酯,可以用于作粘合剂,和细木粉,矿棉粉、石墨粉等为填料,六亚甲基四胺为交联剂制造电木粉绝热板和石墨制品等等:还可以用它来代替合成脂肪酸,配制成“合成粘合剂”,应用于铸制砂芯,其抗拉强度比原有的提高一倍以上。

As the amount of adhesives used in wood products industry will increase significantly in future , research has been intensively focused on the development of new wood adhesives. All raw materials of synthetic adhesives currently used in wood products industry are from natural gas and petrochemicals. In view of the sharp increase in prices of petrochemicals and eventual depletion of nonrenewable materials, there is a pressing need to seek for alternative raw materials for wood adhesives . The renewable resources in our country are abundant, and some of them could be used as raw materials for adhesives. When this is realized, it will not only partially fill the gap in supply of petrochemical raw materials, but also reduce the cost of adhesives. Tn some cases, pollution can be decreased, if spent liquor is used.

由于木工胶粘剂用量不断增长,因此大量研究工作重点放在开发新的木工胶粘剂。考虑到现用胶粘剂的原料均来自天然气及石油化工产品,而这些原料不断提价并且资源逐渐减少趋向枯竭,所以利用其他原料制备木工胶粘剂是非常必要的。我国具有丰富的再生资源,如能利用这些资源制备胶粘剂,以取代现用的石油化工产品原料,这不但可缓解原料供应紧张问题,且能降低胶粘剂的成本,如能利用废料,则尚可达到减少污染的目的。本文总结了近年来国内外利用再生资源作胶粘剂的研究工作进展的情况,着重介绍使用原料易得的工业木素、单宁及碳水化合物等制备木工胶粘剂的状况。并建议应建立试验车间或工厂生产这些胶粘剂,并能加速研究成果早日在生产中应用
