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.
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。
