Abstract
本发明涉及一种用于预浸料的环氧树脂组合物的制备方法,包括如下步骤:步骤1、获取环氧树脂、固化剂、促进剂、阻燃剂、分散剂和增韧剂,且环氧树脂组合物、固化剂、促进剂、阻燃剂、分散剂和增韧剂的质量比为100:2~30:2~15:10~40:0.1~5:1~20;所述环氧树脂由两种组分组成。本发明的环氧树脂组合物不含卤素,树脂中所含磷元素、氮元素、金属氧化物在设定的配比下与酚醛环氧树脂产生协同阻燃效果,使得材料在燃烧时同时进行凝聚相阻燃及气相阻燃,促进树脂表面碳层的形成,释放惰性气体对可燃气体进行稀释,同时释放自由基对燃烧反应中间活性基团进行捕捉,大大提高树脂的阻燃性能。
Description

背景技术
环氧树脂因其独特的分子结构而有良好的工艺性和优异的力学性能是应用最广泛的热固性树脂之一,在航空航天、轨道交通以及船舶和等领域都有着广泛的应用。
随着科技的发展和人们日常生活的需求,防火安全性成为人们无法忽视的问题。环氧树脂阻燃性较差,无法满足航空航天、轨道交通、舰船等工业领域提出的高防火安全性的要求,在对阻燃性能有严格要求的产品中难以得到大量应用。目前阻燃性能好的树脂基复合材料主要以酚醛基复合材料为主,但是酚醛树脂存在力学性能和工艺性能差、且工艺过程或使用过程中有游离酚和甲醛放出等问题。同时酚醛树脂基复合材料所用的预浸料基本采用溶剂法制备,对环境造成较大污染,而溶剂回收和处理的成本也较高。上述原因使得酚醛树脂基阻燃复合材料难以全面满足先进装备对力学性能及环境安全性能的要求。
普通的环氧树脂易燃,并且产生大量的烟甚至毒性气体,热释放率高,其制备的复合材料不具有阻燃性能,防火防毒安全性较差,无法满足航空航天、轨道交通、舰船等工业领域提出的高防火安全性的要求。通过对环氧树脂进行改性,如添加各种无机阻燃剂等,环氧树脂可以实现其阻燃性能的提高,防火安全些可满足轨道交通、航空航天等领域对复合材料阻燃性能的要求。
与此同时由于大量无机填料的加入,使得环氧树脂的韧性和粘性降低,不仅使得自身力学性能下降,并且以这种树脂制备的预浸料在与蜂窝夹层进行夹层结构制件的制备时,往往需要再引入其他结构胶膜来进行粘接,不仅使得制件制备的工艺流程变得繁琐,同时使制件的整体重量增加,难以满足部分领域对构件整体重量的要求。
发明内容
本发明的目的是:提供具有自粘性和阻燃性的环氧树脂组合物及其制备方法,满足在基体树脂中引入联苯结构及端羧基液体丁腈橡胶(CTBN)改性结构,并添加热塑性增韧剂对树脂进行增韧改性,使树脂具有良好的韧性和自粘性,使得该树脂制备的预浸料可无需胶膜直接与纸蜂窝进行粘接,简化蜂窝夹层板构件制备的工艺流程,减少夹层板构件的整体重量。
本发明的技术方案是:
提供一种用于预浸料的环氧树脂组合物的制备方法,所述制备方法包括如下步骤:

进一步的,所述阻燃剂包括三聚氰胺氰尿酸盐、聚磷酸铵、六苯氧基环三磷腈中的两种或三种组合。更优选地,所述阻燃剂还包括三氧化二锑、氢氧化镁、氢氧化铝和三聚磷酸铝中的一种或几种组合;
进一步的,所述分散剂为HYPER 100C、八苯基八硅倍半氧烷或白炭黑中的一种或几种的组合;
