摘要
Abstract
The acrylate silicone coating is used hydroxy-terminated poly(dimethylsiloxane)as the main component,using 3-(dimethoxymethylsilyl)propylamine to react with hydroxyl groups,and then employing the Michael addition of trimethylolpropane triacrylate(TMPTA)and amino to obtain an acrylate silicone prepolymer with a tertiary amine structure(TMPTA-NSi).Then by mixing with DY-MQ102N for UV curing,a new silicone coating was prepared.Through tests such as water contact angle,pencil hardness,SEM and TG.Tested the effect of the addition of DY-MQ102N on the improvement of coating physical properties.The results showed that the water contact angle of the coating increased from 97.3° to 106.5° and the hardness increased from 5B to 2H as the resin content of DY-MQ102N increased.The coating has a compact surface morphology and a high carbon residual rate.This is due to the complex structure of DY-MQ102N,which allows the coating to form a more complex three-dimensional structure during the curing process,resulting in improved physical properties of the coating.关键词
