一种持久稳定的光固化涂料
摘要：
本发明涉及涂料技术领域，具体是关于一种持久稳定的光固化涂料，包括以下重量份的组分制备而成：改性环氧丙烯酸脂66‑78份、新戊二醇二丙烯酸酯15‑29份、邻甲酚醛环氧丙烯酸酯30‑35份、三羟甲基丙烷三丙烯酸酯25‑32份、2‑甲基‑1‑(4‑甲硫基苯基)‑2‑吗啉基‑1‑丙酮5‑8份、甲苯基二苯基磷酸酯22‑26份、聚二甲基硅氧烷4‑7份、硬脂酸钠3‑8份、硬脂酸锌2‑6份、白炭黑7‑15份。本发明采用橡胶改性环氧丙烯酸脂，改性后具有橡胶黏度高、高弹性的特点，多组分协同使涂料附着力强，涂料涂抹后不起泡，隔绝性好，防止基材被腐蚀，涂料具有良好的机械性能，具有较强的抗冲击性，受到撞击后恢复能力强。
摘要（英）：

The invention relates to the technical field of coating, in particular to durable and stable photocurable coating. The durable and stable photocurable coating is prepared from the following components in parts by weight: 66 to 78 parts of modified epoxy acrylate, 15 to 29 parts of neopentyl glycol diacrylate, 30 to 35 parts of o-cresol formaldehyde epoxy acrylate, 25 to 32 parts of trimethylolpropane triacrylate, 5 to 8 parts of 2-methyl-1-(4-methylthio-phenyl)-2-morpholinyl-1-acetone, 22 to 26 parts of diphenyl cresol phosphate, 4 to 7 parts of polydimethylsiloxane, 3 to 8 parts of sodium stearate, 2 to 6 parts of zinc stearate and 7 to 15 parts of white carbon black. According to the durable and stable photocurable coating disclosed by the invention, rubber modified epoxy acrylate is adopted, the durable and stable photocurable coating has the characteristics of high rubber viscosity and high elasticity after modification, the durable and stable photocurable coating has strong adhesion through synergy of multiple components, the durable and stable photocurable coating has no blistering after being painted, the insulation is good, a base material is prevented from being corroded, the durable and stable photocurable coating has good mechanical performance and has stronger impact resistance, and the recovery capability is strong after the durable and stable photocurable coating is impacted.
