Mathematical Model of Anti-aging Indices for Acrylic Polyurethane Coating
摘要
Abstract
The variations of anti-aging indices of acrylic polyurethane coating with the accelerated aging experi-mental time were investigated through xenon lamp indoor accelerated aging test,and the mathematical models between the anti-aging indices and accelerated time were also established preliminarily according to the detection of gloss,color difference and micro-morphology.The test results showed that the relationship between the mathematical models of the gloss and the gloss loss rate with the accelerated experimental time were approximately an exponential function, while the relationship between the mathematical model of the color difference with the accelerated experimental time was approximately a power function.Moreover,the experimental data were well fitted based on the mathematical models in order to get the mathematical relationships,and the correlation coefficients were above 0.99.关键词
