摘要： A rapid curing adhesive for wood finger jointing and laminating and a method of its use are disclosed. The adhesive consists of two parts that are used as a honeymoon system. One part is used on one side of the joint being formed and the other part on the other side. When the parts are joined under pressure a very rapid reaction occurs resulting in a durable weather resistant joint. Wood finger joints bonded with the adhesive can be handled for further processing within as little time as 15 seconds. The first part of the adhesive is a conventional resorcinol-formaldehyde or phenol-resorcinol formaldehyde resin containing a hardener such as an alkylene group donor. The second part is a similar resin lacking any hardener but containing a modifier which is a heterocyclic oxygen and nitrogen containing compound. Morpholine has proved to serve well as the modifier. The hardener in the first part is used in a sufficient amount to effect a thermosetting cure for the resin used in both parts. Despite the rapid reaction when the two parts are combined, the adhesive has a significant closed assembly time tolerance before application of full pressure to the joint.
摘要翻译：公开了一种用于木指接合和层压的快速固化粘合剂及其使用方法。粘合剂由用作蜜月系统的两部分组成。一部分用于形成的接头的一侧，另一部分用于另一侧。当部件在压力下接合时，发生非常快速的反应，导致持久的耐候性接头。与粘合剂粘合的木指接头可以在15秒钟内进行进一步处理。粘合剂的第一部分是含有诸如亚烷基供体的固化剂的常规间苯二酚 - 甲醛或酚 - 间苯二酚甲醛树脂。第二部分是不含任何硬化剂但含有杂环含氧和含氮化合物的改性剂的类似树脂。已经证明吗啉作为改性剂。使用第一部分中的固化剂足够量以对两部分中使用的树脂进行热固化固化。尽管组合两个部分时，快速反应，但是在向接头施加全压之前，粘合剂具有显着的闭合组装时间公差。
