Abstract

Introduction: The possibility of regulating the curing rate and the complex of adhesive, deformation-strength and dynamic mechanical properties of polymers based on bisphenol A dithioester (thiirane) using a mixture of amine hardeners of various chemical nature is investigated. Method: Diethylenetriamine, diethylenetriaminomethylphenol and aminopolyamide were investigated as hardeners. The ratio of the components of the mixed hardener is selected, which provides the best combination of strength properties. Results: It was found that the rate of adhesion and cohesive strength at the initial stage (during the first hour) of curing compositions containing a mixture hardener significantly exceeds compositions cured by individual components of the mixture. Conclusion: The results of measuring the dynamic mechanical characteristics of the studied polymers indicate that the dynamic modulus of elasticity, measured at temperatures below and above the transition from a glassy state to a high elastic one, for a sample containing a mixed hardener has an intermediate value between the values characteristic of samples containing individual components of a mixed hardener. The ratio of the components of the mixed hardener is selected, which provides the best combination of strength properties.

使用胺类硬化剂混合物调节基于巯基乙烷的聚合物的性能
简介研究了使用不同化学性质的胺类固化剂混合物调节双酚 A 二硫酯(硫烷)聚合物的固化速率以及粘合力、变形强度和动态机械性能的可能性。方法:研究了作为固化剂的二乙烯三胺、二乙烯三胺甲基苯酚和氨基多酰胺。选择混合固化剂中各组分的比例,以获得最佳的强度性能组合。研究结果结果发现,含有混合固化剂的固化组合物在初始阶段(第一小时)的粘附率和内聚强度明显高于由混合物的单个成分固化的组合物。结论对所研究聚合物的动态机械特性进行测量的结果表明,在低于和高于从玻璃态向高弹性态过渡的温度下测量的含有混合固化剂的样品的动态弹性模量,其数值介于含有混合固化剂单个成分的样品的数值之间。
