Tensile Mechanical Behavior of a New High-Temperature Resin, Polyethersulfone Ketones with Diazanone Structure
-
摘要: 为探索新型耐高温树脂——含二氮杂萘酮结构的聚醚砜酮(简称“PPESK”)的拉伸力学行为,本文采用对比实验的方式,以典型商用树脂——聚醚醚酮(简称“PEEK”)为参照,从耐热性、拉伸性能对拉伸速率变化的敏感性、拉伸变形-断裂行为三个层面详细分析了PPESK力学行为的特殊之处。研究表明,PPESK的耐热性远优于PEEK,且强度和模量对拉伸速率变化更敏感。在室温至250℃时,形变量在6%以内,发生脆性断裂;仅当温度达260℃及以上时,PPESK才出现较大变形,发生韧性断裂,这与各种条件下均产生大变形且韧性断裂的PEEK截然不同。上述特殊力学行为的产生,与PPESK结构中扭曲、非共平面的杂萘环以及强极性的砜基、羰基有关。这些基团使PPESK为无定形形态,且分子链刚性增大、分子间作用力增强,进而引起玻璃化转变温度升高、分子运动能力下降,导致PPESK更耐热、拉伸性能对拉伸速率变化更敏感,断裂形式以伴随主链断裂的脆性断裂为主。

Abstract: In order to explore the tensile mechanical behavior of a new high temperature resistant resin, Polyethersulfone ketones with diazanone structure ("PPESK"), a comparative experiment was conducted in this paper, and a typical commercial resin, Polyetheretherketone ("PEEK"), was used as a reference. The special mechanical behavior of PPESK was analyzed in detail from three aspects: heat resistance, sensitivity of tensile property to the change of tensile rate, and tensile deformation to fracture behavior. It is shown that the heat resistance of PPESK is much better than that of PEEK, and the strength and modulus are more sensitive to tensile rate changes. At room temperature up to 250℃, the deformation is within 6%, and brittle fracture occurs; only when the temperature reaches 260℃ and above, PPESK shows large deformation and toughness fracture occurs, which is very different from PEEK, which produces large deformation and toughness fracture under various conditions. The generation of the above special mechanical behavior is related to the twisted, non-coplanar heteronaphthalene ring in the structure of PPESK, as well as the strongly polar sulfone group and carbonyl group. These groups make PPESK amorphous form, and the molecular chain rigidity increases, the intermolecular forces increase, which in turn causes the glass transition temperature increases, the molecular movement ability decreases, resulting in more heat-resistant PPESK, tensile properties of more sensitive to changes in tensile rate, the form of fracture to the brittle fracture accompanied by the breakage of the main chain is dominant. -
