一种UV光固化树脂固化动力学模型的建立
An establishment of a UV photocuring resin curing kinetic model
摘要
Abstract
The study of photocuring kinetics is an important part of photocuring research.Using an external UV light source coupled with differential scanning calorimetry,the photocuring behavior was tested at different light in-tensities and temperatures.This investigation provided heat flow curves,curing degree curves,and curing rate curves for the resin during the curing process.The autocatalytic model was used to fit the curing rate curves.The parameters obtained were fitted using linear or nonlinear regression to establish the curve function relationship.Previous studies had limitations as they almost considered the effect of a single variable on the photocuring kinetics model.This paper proposed a hypothesis that simultaneously incorporated curing temperature and light intensity as variables within the derived photocuring kinetic equation.The reliability of the proposed photocuring kinetics model was verified by com-parison between actual experiment and finite element curing simulation.The maximum error between simulation and actual experiment is calculated to be no more than 6.5％.This study extends the understanding of photocuring kinetics and provides new perspectives and methods for optimizing the photocuring process.关键词
