Description

一种脂环胺固化剂及其制备方法
技术领域
本发明属于化工领域，涉及一种高分子材料，具体涉及一种环氧树脂固化剂，特别是一种腰果酚脂环胺固化剂及其制备方法。
背景技术
胺类固化剂与空气中的CO2反应生成不能与环氧基起反应的碳酸铵盐而引起气泡的发生。脂肪胺对皮肤有一定刺激作用，其蒸汽毒性很强。现有腰果酚固化剂色深，固化速度较慢。
发明内容
本发明的目的在于提供一种脂环胺固化剂及其制备方法，所述的这种脂环胺固化剂及其制备方法要解决现有技术中的胺类固化剂使用过程中容易产生气泡，而且固化时间长的技术问题。
本发明提供了一种腰果酚脂环胺固化剂，其结构式如下：
n＝1～100。
(I)
本发明还提供了上述腰果酚脂环胺固化剂的制备方法，包括如下步骤：
1)一个制备十五烷基酚的步骤，以腰果酚为原料，通入氢气，加入催化剂，在3～5MPa的压力下60～90℃进行反应，获得十五烷基酚；
2)在十五烷基酚中加入聚甲醛或者甲醛、脂肪胺或者芳香胺，所述的脂肪胺为乙二胺、二乙烯三胺、三乙烯四胺、四乙烯五胺、或多乙烯多胺；；所述的十五烷基酚、聚甲醛或者甲醛、脂肪胺的摩尔比为1:1～2:1～2；在60～80条件下进行反应，1～4小时后，获得中间体酚醛胺；
3)将步骤2)获得的中间体酚醛胺减压脱水后，再加入催化剂，在3～5MPa的压力下90～110℃进行反应，1～3小时后获得通式(I)所示的脂环族的腰果酚改性固化剂。
进一步的，所述的催化剂为雷尼镍。
本发明以腰果酚为原料，通过雷尼镍氢化腰果酚，首先得到十五烷基酚，再用甲醛及乙二胺(或二乙烯三胺，三乙烯四胺，四乙烯五胺，多乙烯多胺，等脂肪胺)连接胺类，合成中间体酚醛胺，再将中间体酚酚醛胺能过雷尼镍氢化苯环得到一种固体的，浅色，可快速固化的，高附加值的在高温下使用的脂环族的腰果酚改性固化剂。
本发明的反应过程如下所示：
本发明通过改性脂肪胺再氢化得到脂环胺。由于脂环胺分子量大，不易挥发，在室温很快固化环氧树脂，固化反应为放热反应，热量能进一步促使环氧树脂与固化剂反应，其使用期较短。
本发明和已有技术相比，其技术效果是积极和明显的。本发明首先能过雷尼镍氢化腰果酚，以保证在氢化腰果酚合成中间体过程中颜色较浅，不变深；再将中间体氢化得到脂环胺，以保证该脂环胺具有较浅的颜色，且该脂环胺具有的性质为固体，浅色，可快速固化，附加值高。
