THE INFLUENCE OF REACTIVE DILUENT ON REOKINETICS OF HEAT-RESISTANCE BINDERS BASED ON POLYFUNCTIONAL EPOXY RESIN

Abstract

Reokinetic properties of multifunctional epoxy resin at diffrent temperatures with low-viscosity reactive diluents containing glycidyl ether, and the glass transition temperature and the degradation temperature of heat-resistant polymer matrix was investigated. The reactive diluents increases the glass transition temperature at 37°C, reduces the viscosity of 4 times, and the curing time is not changed. It was developed technological polymer binder based on epoxy resin and reactive diluents with low viscosity, and high glass transition temperature (~ 280о С) and degradation temperature ~ 335°С.
