Modifications of viscoelastic properties of natural rubber/styrene-butadiene rubber blend by electron beam irradiation

Popis výsledku v původním jazyce

The influence of high-energy electron beam irradiation on the viscoelastic properties of natural rubber/styrene-butadiene rubber blend has been investigated in the study presented in this paper. Changes in viscoelastic properties were studied as a function of radiation dose and temperature using the dynamic mechanical analysis in the temperature range from 10 to 240 oC at frequency of 0.5 Hz. The samples of material under the investigation were irradiated in the presence of air, at room temperature, using the 5 meV electron beam in the dose range from 50 to 300 kGy, with the maximum beam power of 50 W. The experimental results have shown that an increase in the radiation dose leads to an increase in the storage modulus and a corresponding decrease in the damping factor. With increasing radiation dose, the curing process of tested rubber blend begins and ends at lower temperatures, with a higher initial and final storage modulus and a lower initial damping factor, whereas the radiation dose has almost no impact on the final value of damping factor. The unified regression model describing analytically the dependence of all monitored properties of tested rubber blend on radiation dose with a high level of reliability was found as well using the multi-parametric fitting technique by a trust region algorithm of a nonlinear least-squares method.
