摘　　要：为改善紫外光(UV)固化环氧丙烯酸酯(EA)涂层的阻燃性能,使其适用于木制家具、古木建筑文物、布艺家饰及公共场所舞台装饰等领域的防火阻燃,以丙烯酰胺与γ-缩水甘油醚氧丙基三甲氧基硅烷(KH560)为原料合成了含氮、硅功能单体(NSFM),将其与EA复配,经UV固化制备出具有阻燃功能的透明涂层。利用傅里叶变换红外光谱仪、紫外-可见分光光度计、极限氧指数(LOI)测定仪、垂直燃烧测定仪及力学测定仪等测定了涂层的性能。该涂层可见光透过率及实际透明性考察均表明其透明性能满足透明阻燃涂层基本要求;同时随阻燃单体的加入,涂层的附着力、抗冲击性及硬度等性能均得到改善。当NSFM质量分数达50%时,涂层的附着力、硬度、抗冲击性、LOI值、燃烧级别及热释放速率峰值均达到最佳,分别为2级、4H、65 kg·cm、30、V-0级及387.3 kW·m^(-2)。研究结果表明,设计具有多羟基且含Si和N活性阻燃单体在阻燃改性EA涂层的同时也进一步改善了其力学性能,并保持了其良好的透明性,该涂层有望应用于木质文物的防火阻燃领域。To improve flame-retardant performance of UV-cured epoxy acrylate(EA)coatings and make them suitable for flameretardant wood furniture,ancient wood building cultural relics,cloth art home ornaments,public place stage decoration and other fields,the functional monomer NSFM containing N and Si was synthesized from acrylamide and KH560 as raw materials,and transparent flame-retardant coatings were prepared by UV-curing method after the above functional monomer was mixed with the EA formula system.The coatings’properties were characterized by Fourier transform infrared spectrometer,UVvisible spectrophotometer,limiting oxygen index(LOI)tester,vertical burning tester,thermogravimetry,etc.The investigation of the visible light transmittance and actual transparency of the coatings showed that the transparency performance could meet the basic requirements of transparent flame-retardant coatings.At the same time,with the addition of flame-retardant monomer,the adhesion,impact resistance and hardness of the coatings were improved.When the NSFM content reached 50%(wt%),the coatings’adhesion,hardness,impact resistance,LOI value,combustion level and peak heat release rate were the best,reaching grade 2,4H,65 kg·cm,30,V-0 and 387.3 kW·m^(-2) respectively.The results showed the designed active flame-retardant monomer with polyhydroxyl group,Si and N modified the flame-retardant EA coatings while further improving the mechanical properties and maintaining the good transparency.The coatings are expected to be used in the field of flame-retardant wood cultural relics.
