Description
技术领域
本发明涉及涂料材料领域,特别涉及一种水性双组份涂料用固化剂组合物及其制备方法与应用。
背景技术
由于水性树脂原料粘度高以及高速分散容易导致树脂破乳等原因,目前水性环氧涂料在制造过程中广泛使用水磨浆的工艺。该工艺繁琐,制造周期长,能耗大,制造过程中需要添加含有VOC的助剂,需要额外的水,导致产品的固含量低,涂料施工时需要多次涂装才能达到理想的效果,能耗大,周期长,通过该工艺生产的水性双组份涂料只能替代油性产品VOC大于420g/L的涂料,不能替代其他含有VOC的油性产品(VOC小于420g/L)。为进一步降低生产过程中的能耗和有害物质排放,提升水性环氧涂料品质,实现绿色生产,亟需对涂料生产工艺进行改进。
环氧树脂的固化反应是通过加入固化剂,利用固化剂中的某些基团与环氧树脂中的环氧基或羟基发生反应来实现的。固化剂是影响水性环氧涂料性能的关键因素之一。传统的溶剂型固化剂难以与水性环氧涂料混溶,所以针对水性环氧体系必须用水性环氧固化剂才能解决此问题。普通的脂肪族胺类固化剂对人体刺激较大,同时易于与空气中CO2反应生成盐,或吸收潮气泛白,因此实际使用水性环氧固化剂多为多胺与环氧树脂加成产物。但目前改性胺固化剂仍存在多种缺陷,例如耐侯性差、易变黄,柔韧性、附着力也欠佳。
发明内容
技术问题:为了解决现有技术的缺陷,本发明提供了一种水性双组份涂料用固化剂组合物及其制备方法与应用。
技术方案:本发明提供的一种水性双组份涂料用固化剂,其结构式如式I所示:
本发明还提供了上述水性双组份涂料用固化剂的制备方法,包括以下步骤:将三苯基甲烷三异氰酸酯溶于二氯甲烷中,加热至50-60℃恒温,边搅拌边滴入式II所示的化合物,在2h内滴完,滴完后恒温反应1-2h,即得;反应式如下:
本发明还提供了水性双组份涂料用固化剂组合物,由以下重量份的组份制得:三苯基甲烷三异氰酸酯2重量份、聚乙二醇单甲醚2-4重量份、式I所示的化合物1-4重量份;式I所示的化合物结构式如下:
本发明还提供了水性双组份涂料用固化剂组合物的制备方法,包括以下步骤:
(1)将三苯基甲烷三异氰酸酯溶于二氯甲烷中,加热至50-60℃恒温,边搅拌边滴入式II所示的化合物,在2h内滴完,滴完后恒温反应1-2h,即得;反应式如下:
(2)将步骤(1)的产物与三苯基甲烷三异氰酸酯、聚乙二醇单甲醚混匀,即得。
优选地,各组份的重量份为:三苯基甲烷三异氰酸酯2重量份、聚乙二醇单甲醚2-4重量份、式I所示的化合物1-4重量份。
有益效果:本发明制得的固化剂引入甲基(甲磺酰基)氨基甲酸对异氰酸酯进行封闭,可稳定保存,同时使用时仅需要稍加热即可实现解封,固化速度可根据加热温度控制;固化剂具有三个NCO基团,且三个NCO基团消去温度有差别,不仅能大大减少异氰酸酯的用量,而且可控制反应速度和程度。
为了在初始时即可快速反应,本发明还提供了固化剂组合物,组合物中也包括三苯基甲烷三异氰酸酯,从而避免交联反应初始反应过慢,特别是温度较低时。
