Abstract

In this study, we evaluated an effect of the tempered materials on the thermal runaway characteristics in the resol resin synthesis reaction using the adiabatic calorimetry of vent sizing package 2(VSP2). The kinetic parameters, such as an activation energy and heat of reaction, were estimated using the test results. As the results, the instantaneous characteristics to express the intensity of runaway reaction decreased at the low solid content. However, the sudden loss of the tempered materials triggered the second runaway reaction rapidly. In this condition, the heat of reaction and the activation energy of phenol and p-formaldehyde were about 157 kJ/mol and 60 kJ/mol, respectively.

본 연구에서는 단열열량계의 일종인 폭발열량 측정장치를 이용하여 레졸수지 합성반응에서 온도조절 물질이 열폭주 특성에 미치는 영향을 평가하고, 반응열과 활성화에너지 등의 속도론적 데이터를 검토하였다. 그 결과, 온도조절 물질이 투입된 낮은 고형분 농도에서는 폭주반응의 격렬함을 나타내는 순간 특성치들이 감소했다. 그러나 투입된 온도조절 물질의 갑작스런 소실은 급격한 2차 폭주반응을 촉발시켰다. 이때, 레졸수지 합성반응의 폭주반응에 의한 반응열은 페놀을 기준으로 약 157 kJ/mol이었고, 활성화에너지는 약 60 kJ/mol로 나타났다.
