Description

一种稳定剂组合物及其制备方法和由其组成的模塑组合物 技术领域
本发明涉及一种稳定剂组合物,具体涉及一种含碳二亚胺组分的稳定剂组合物及其制备方法和由其组成的模塑组合物。
背景技术
在湿热环境下,含酰胺基或酯基结构的聚酰胺,聚氨酯和聚酯等聚合物会慢慢降解并且会降低其性能。有机碳二亚胺类化合物是一种优良的抗水解稳定剂,可以使分解的羧基与碳二亚胺反应而避免继续降解聚合物,在聚酰胺、聚氨酯和聚酯等聚合物体系添加了有机碳二亚胺类化合物,可以减缓其降解速℃,有效的提高其抗水解性能。
目前工业上最广泛应用的抗水解稳定剂有德国拜耳公司子公司莱茵化学公司的Stabaxol 1、Stabaxol P 200和德国Raschig GmbH公司的Stabilizer 7000等。
异氰酸酯法是目前合成芳香基碳二亚胺最主要的方法。1970年美国专利US3502722最早提出了N,N’-二(2,6-二异丙基苯基)碳二亚胺的结构及其制备方法,通过两分子的异氰酸酯在催化剂的作用下加热缩合并脱二氧化碳即可得到目标产物。在此基础上,欧洲专利11164899.4和11188364.1又公开了用类似方法合成的聚合型碳二亚胺产品。
中国专利200910159208.1公开了一种合成N,N’-二(2,6-二异丙基苯基)碳二亚胺的新方法,用胺和硫脲反应缩合得到取代基硫脲,然后再氧化即可得到目标产物。
近几年来,多种新型的双碳二亚胺和聚合型碳二亚胺化合物的结构、制备方法以及应用相继被提出,和单碳二亚胺相比,这些化合物具有更高的熔点,更容易添加到聚合物体系中。
如中国专利200910137135.1,揭示了一种通过异硫氰酸酯合成新型结构双碳二亚胺的方法,其结构如下:
Figure PCTCN2015097210-appb-000001
中国专利201110315326.X,揭示了一种通过异氰酸酯合成新型结构聚合型碳二亚胺的方法,其结构如下:
Figure PCTCN2015097210-appb-000002
中国专利201310443228.3,揭示了一种通过异硫氰酸酯合成新型结构双碳二亚胺的方法,其结构如下:
Figure PCTCN2015097210-appb-000003
中国专利201410173816.4,揭示了一种通过异氰酸酯合成新型结构聚合型碳二亚胺的方法,其结构如下:
Figure PCTCN2015097210-appb-000004
碳二亚胺类抗水解剂产品能有效改善聚合物体系的抗水解性,但为了进一步提高聚合物体系的抗水解性,就需要加入其他共稳定剂,如中国专利200780020729.3揭示了一种水解稳定剂,通过在碳二亚胺中添加氧化铝或羟基氧化铝作为共稳定剂,和单独使用碳二亚胺相比,能使聚合物体系的抗水解性进一步提升。然而此专利中提到的共稳定剂主要为非碳二亚胺化合物,且需要另外添加到碳二亚胺类抗水解剂中,在混合的过程中往往会遇到相容性的问题,从而会一定程度上影响到抗水解剂的性能。
发明内容
本发明的目的在于提供一种含碳二亚胺组分的稳定剂组合物及其制备方法,该组合物添加到含有酰胺基或酯基结构的聚合物中,可有效改善聚合物体系的抗水解性能。
