摘要:

通过两步反应法实现了硅烷偶联剂KH550和羟基硅油对环氧树脂E-20的共同改性,利用胺基加成反应引入KH550的乙氧基基团增加E-20的活性,从而提高与羟基硅油的接枝效率。通过红外光谱、GPC测试、稳定性分析以及DSC测试研究了分步反应过程和反应物配比对改性树脂性能的影响,优化改性工艺。研究表明,合适的反应物配比为E-20∶羟基硅油∶KH550=10∶1.5∶0.5 (质量比)。进一步利用改性树脂配制富镁涂层,通过涂层基本性能测试、盐雾试验和老化试验,研究了涂层对铝合金的保护性能。研究表明,涂层具有高的附着力,柔韧性好,耐盐雾和耐老化性能提高明显。

关键词 ：富镁涂层, 接枝聚合, 环氧树脂改性, 铝合金保护

Abstract：

Epoxy resin (E-20) was co-modified by silane coupling agent (KH550) and hydroxyl silicone oil through a two-step reaction process. The ethoxy group (coming from KH550) was introduced into E-20 by addition reaction of primary amine to increase the activity, thereby the grafting efficiency of E-20 with hydroxyl silicone oil was improved. The mechanism of two-step reaction process and the effect of reactant ratio on properties of modified resin were studied in detail through IR, GPC test, stability analysis and DSC test so that to optimize modification parameters. The results show that the appropriate ratio of reactants was E-20: hydroxyl silicone oil: KH550=10:1.5:0.5 (mass ratio). Further, the Mg-rich primer made of the modified resin was prepared and then applied on Al-alloy, afterwards the protective performance for the Mg-rich primer coated Al-alloy was assessed through salt spray testing and aging testing. The results show that this coating has high adhesion and good flexibility, as well as excellent salt spray resistance and aging resistance.

Key words： Mg-rich coating graft polymerization modification of epoxy resin protection of Al-alloy
