Molecular Size Effect on Curing Process for Epoxy and Amine Mixture
نویسندگان
چکیده
The curing process of epoxy and amine mixtures was investigated from the viewpoint molecular size reactants via all-atom dynamics simulation. Of four composed either smaller or larger molecules, system both reached highest conversion at a given time, whereas for combination lowest. These can be explained in terms their diffusion coefficients. In addition, effect on reaction kinetics more striking than process. This because reacted only once but did twice. When primary with epoxy, resultant secondary incorporated into three-dimensional network. Hence, even if had higher mobility, movement part after slowed down, making further to tertiary slow. Finally, it shown that although faster one mixed larger/smaller amine, there no difference progress depending amine.

Effect of cure cycle on curing process and hardness for epoxy resin
A 3-dimensional finite element model is developed to simulate and analyze the temperature and degree of cure field of epoxy casting part during cure process. The present model based on general finite element software ABAQUS is verified by literature example and experimental data. The numerical results show good agreement with literature example and measured data, and are even more accurate than...
متن کاملOptimization of thermal curing cycle for a large epoxy model
Heat generation in an exothermic reaction during the curing process and low thermal conductivity of the epoxy resin produces high peak temperature and temperature gradients which result in internal and residual stresses, especially in large epoxy samples. In this paper, an optimization algorithm was developed and applied to predict the thermal cure cycle to minimize the temperature peak and the...

Epoxy – Polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.To strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (Epon828) as hard segment was studied. FT-IR spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer. Results obtained f...
متن کاملSelf-curing with epoxy groups
Isocyanate-free cathodic ED coatings. Most of the resins used in the cathodic electrodeposition (CED) coatings are made from modified epoxy resin and blocked polyisocyanate in which the crosslinking is achieved by polyurethane and polyurea formation. A resin system has been developed that is isocyanate free and avoids not only the toxicity aspect, but also, to a great extent, the weight loss of...
