邻苯二甲酰β-丙氨酸钙对聚丙烯性能的影响
|
摘要
将自制的邻苯二甲酰β-丙氨酸钙进行了IR、TG表征。同时,将其与邻苯二甲酰甘氨酸、邻苯二甲酰甘氨酸钙以及市售成核剂WBG-Ⅱ进行性能对比。结果表明:这种新型成核剂是一种有效的聚丙烯成核剂。当添加量为0. 2%时,冲击强度由纯PP的4. 1 k J/m2提升至8. 3 k J/m2。与添加WBG-Ⅱ成核剂后冲击强度提升65%相比,新型成核剂能使聚丙烯的冲击强度再提高37%。另外,添加其他2种成核剂PG、PG-Ca后,其他力学性能如拉伸强度和弹性模量均下降3%～5%,但添加新型成核剂邻苯二甲酰β-丙氨酸钙后,拉伸强度和弹性模量均有小幅提升,分别提升了2. 5%和5%。添加新型成核剂后,聚丙烯生成的β晶含量(40%)与其他3种成核剂(80%～90%)相比,略有不足。
The self-made calcium phthalyl β-alanine was characterized by IR and TG. At the same time,calcium phthalylβ-alanine was compared with phthalylglycine,phthalylglycine calcium and marketed nucleating agent WBG-Ⅱ. The results showed that this new nucleating agent was an effective nucleating agent for polypropylene. When the addition of calcium phthalyl β-alanine was 0. 2%,impact strength of pure PP increased from 4. 1 kg/m2 to 8. 3 kg/m2.Compared with the 65%increase in impact strength after the addition of the WBG-II nucleating agent,the impact strength increased by 37% more with the addition of the calcium phthalyl β-alanine,after the addition of two other nucleating agents,PG and PG-Ca. In contrast,after adding calcium phthalyl β-alanine,tensile strength and elastic modulus were raised by 2. 5% and 5%,respectively.However,when the new nucleating agent was added,the content of beta crystal formed by polypropylene( 40%) was slightly less than that of the other three nucleating agents( 80% ～ 90%).
