摘要：以腰果酚为原料制备氢化腰果酚(HC),再与烯丙基缩水甘油醚(AGE)反应合成烯丙基醚型氢化腰果酚(AGE-HC),进一步与甲基丙烯酸酐(MAA)反应合成烯丙基醚酯型氢化腰果酚(MAA-AGE-HC)。以烯丙基醚型腰果酚(AGE-C)和烯丙基醚酯型腰果酚(MAA-AGE-C)为对照样,采用红外光谱、凝胶渗透色谱研究了烯丙基腰果酚单体的紫外光固化反应特性。研究结果表明:烯丙基腰果酚单体的最佳光固化反应条件为无极灯光源(铁灯,主波长365 nm),功率1500 W,辐照距离40 mm,辐照时间60 s,引发剂2-羟基-2-甲基-1-苯基-1-丙酮(1173)用量为单体质量的3%;烯丙基腰果酚的光固化反应活性由高到低依次为MAA-AGE-C>MAA-AGE-HC>AGE-C>AGE-HC≈腰果酚;腰果酚在有氧或光引发剂条件下可紫外光固化,紫外光固化过程温度升高可协同加速固化反应,使腰果酚快速固化;烯丙基酯、烯丙基醚和烯丙基烷基在紫外光固化过程中,依据基团反应活性高低分步固化,主要通过光、热引发自由基聚合反应实现烯丙基单体的固化。
The hydrogenated cardanol(HC)was prepared from cardanol,and then reacted with allyl glycidyl ether(AGE)to synthesize allyl ether type hydrogenated cardanol(AGE-HC).The AGE-HC reacted with methacrylic anhydride(MAA)to form allyl hydrogenated cardanol with ether bond and ester bond(MAA-AGE-HC).The characteristics of UV curing reaction of allyl cardanol monomers were studied by Fourier transform infrared spectroscopy(FT-IR)and gel permeation chromatography(GPC),with allyl ether type cardanol(AGE-C)and allyl cardanol with ether bond and ester bond(MAA-AGE-C)as contrast.The results showed that the optimal UV curing reaction conditions of allyl cardanol monomers were as follows:electrodeless lamp(iron lamp,main wavelength 365 nm)as UV source,power 1500 W,irradiation distance 40 mm,irradiation time 60 s,2-hydroxy-2-methyl-1-phenyl-1-acetone(1173)as initiator with the dosage of 3%of the monomer by weight.The UV curing activities of allyl cardanols were MAA-AGE-C>MAA-AGE-HC>AGE-C>AGE-HC≈cardanol.Cardanol could be cured by UV light under the condition of oxygen or photoinitiator.The curing reaction rate could be accelerated by the combination of UV and high temperature.Furthermore,the allyl ester,allyl ether and allyl alkyl were gradually cured according to the activity of functional groupsby the photoinitiated radical polymerization and thermal initiated oxygen radical polymerization.
