LUYOR-3500L紫外交聯(lián)儀原文描述
UV aging was conducted in a LUYOR UCL-3500L UV cross-linking chamber (Shanghai, China). Coatings were positioned 20 cm directly beneath a 90-watt UV lamp (wavelength: 365 nm) for 168 h of continuous exposure.
紫外老化后涂層表觀與性能原文
Following 168 h of UV irradiation, the coating exhibited slight color deepening without observable blistering or chalking. After UV aging, the retention rates of the freezing delay times for PAT?, PAT?, and PAT? are 70.2%, 77.6%, and 71.6%, respectively, while the corresponding retention rates of ice adhesion strength are 69.7%, 83.4%, and 84.1%, respectively. The coating’s UV resistance is primarily attributable to the absence of free radicals in PDMS and copolymer polymer chains, which prevent photochemical degradation. Additionally, UV attenuation is enhanced through π→π* electron transitions in the aromatic ring system, where increased benzene ring density improves radiation absorption.
紫外老化后紅外結(jié)構(gòu)分析原文
FTIR analysis has been conducted on the PAT coating that underwent a 168 h UV aging test. The results of this analysis are then compared with those of the original sample. UV irradiation accelerated the oxidation/rearrangement of organic components in the cured network, and the magnitude of structural changes is proportional to the APD ratio.
