Description
技术领域
本发明涉及固化剂领域,具体涉及一种水性非离子固化剂。
背景技术
目前常用的环氧-多胺加成物类阳离子水性环氧固化剂,在使用时候会产生挥发性有机酸成盐,给涂膜性能及环境带来的不利影响。因此开发非离子型水性环氧固化剂是作为水性环氧固化剂发展大方向之一。
在非离子水性固化剂合成改性反应中使用脂肪胺引入亲水性的聚醚使其具有强有力的亲水性以及表面活性,然后引入环氧树脂分子链使其具有与环氧树脂相匹配的分子结构从而能够不依靠乳化剂乳化树脂,经过两步扩链合成兼具固化和乳化环氧树脂的固化剂。
但目前此类非离子水性固化剂一般是用二乙烯三胺(DETA)、三乙烯四胺(TETA)作为胺原料改性制作水性固化剂;但改性以后的固化剂与环氧树脂存在操作时间太短(适用期)的问题;同时使用这类水型环氧固化剂的等待固化时间(干燥时间)相对较长。另外此类操作时间内不使用完毕,会造成施工材料的浪费与大量的固体废料。
发明内容
本发明针对上述现有技术存在的问题,提供一种水性非离子固化剂,相对与现有的固化剂能够有更长的适用期、更短的干燥时间。
为实现本发明目的,通过以下技术方案予以实现:
一种水性非离子固化剂,包括组分:有机胺、活性稀释剂501、活性稀释剂205和活性稀释剂215。
优选地,所述有机胺为二乙烯三胺或三乙烯四胺。
进一步优选地,以摩尔计算,包括以下组分:
更进一步优选地,以摩尔计算,包括以下组分:
本发明制成的固化剂适用期(25℃)能长达70min,干燥时间3h后硬度能达到2H级,附着力达到1级。本发明制成的固化剂相对与现有的同类固化剂,其适用期更长,干燥时间更短,给予实际使用更大的缓冲空间。
具体实施方式
下面具体实施例对本发明作进一步说明,以使本领域技术人员可以更好的理解本发明并能予以实施,但所举实施例不作为对本发明的限定。按照本领域的普通技术知识和惯用手段,在不脱离本发明上述基本技术思想前提下,对本发明上述结构做出的其它多种形式的修改、替换或变更,均应落在本发明的保护范围。

本发明中的硬度按照GBT 6739-2006中色漆和清漆铅笔法测定漆膜硬度的方法测定。
本发明的附着力按照GB 1720-1989中漆膜附着力测定法测定。
