摘要
研究了一种室温固化，可在１２０℃下使用的环氧树脂胶粘剂。通过ＣＴＢＮ增韧改性，获得了较高的剥离强度和剪切强度，通过加入高官能度环氧树脂和改性芳胺及催化剂，使得该体系具有一定的耐温性和可室温固化性。
Room temperature curable epoxy adhesive for elevated temperature was introduced. The compositions were bosed on high functionality epoxy resin toughened with carboxyl terminated polybutadiene -- acrylonitrile(CTBN). The curing agents were composed of modified aromatic amine and tertiary amine catalysies. The experimental results showed that the selected compositions could develop good high temperature(120℃) properties and high 90°-- peel strength while cured at room temperature.
