辐照固化涂料进展（Ⅱ）

3 阳离子光固化体系 阳离子光固化体系的发展较自由基光固化体系为晚,因为阳离子的光固化反应是以阳离子聚合为基础的,而阳离子聚合通常要求在低温无水条件下进行,条件比自由基聚合苛刻。这种观念妨碍了阳离子光固化体系的发展。实际上光固化反应与聚合反应有很大不同,光固化反应不要求得到长链聚合物,尽管阳离子聚合在有水和高温下易于发生链终止,但链终止时仍可产生新的活性中心（质子或其它阳离子）,它们仍可和双键发生加成,引发新的反应,其链终止相当于链转移,并不影响多官能基单体、齐聚物间的交联反应,最终得到固化材料。阳离子固化体系有明显的优点如不怕氧气,固化时体积收缩问题可以得到控制。阳离子光固化体系和自由基光固化体系一样,分引发体系与树脂两部分。3.1 阳离子光引发体系

Coating performance and characteristics for UV-curable aliphatic urethane acrylate coatings containing norrish type I photoinitiators

The purpose of this study was to investigate the influence of several Norrish I (α-cleavage) type photoinitiators and UV dose on the curing behavior and coating performance of UV-curable aliphatic urethane acrylate coatings.

New developments in radiation-curable powder coatings

Radiation-curable powder coatings are now in the early stages of commercialization. For years, the coatings industry has sought ways to lower the curing temperature of powder coatings. UV-curable powder coatings offer the possibility of curing powder coatings at temperatures as low as 120°C. Radiation-curable powder coatings also offer high cure speed and relatively low energy consumption. As each application requires its own coating performance, two different maleate-vinyl ether-based binders for UV-curable powder coatings have been developed. With these binders the balance between flexibility and hardness of the coating can be adjusted with proper formulation. In this paper, the curing characteristics and coating performance of several UV-powder coating formulations are described. In addition, a comparison between conventional powder coatings and UV-powder coatings is provided.

Soy-based UV-curable thiol–ene coatings

Novel soy-based thiols and enes were synthesized and characterized. Then, soy-based thiol–ene UV-curable coatings were formulated and their coating physiochemical properties were investigated in detail. The use of biorenewable resources, combined with environmentally friendly UV-curable technology, provides a “green + green” solution to the stricter regulations in the coatings industry. Novel soy-based thiols and enes were synthesized through the Lewis acid-catalyzed ring opening reaction of epoxidized soybean oil with multifunctional thiols or hydroxyl functional allyl compounds. FTIR and NMR confirmed the formation of the target compounds. The soy-based thiols and enes were formulated with petrochemical-based enes and thiols, respectively, to make thiol–ene UV-curable coatings. Typical coating film properties, thermal properties, and photopolymerization kinetics of these coatings were studied. Soy-based thiol–ene coatings having lower functionality thiols and enes have poor UV curability and coating properties, which was attributed to the lower crosslink density. Soy-based thiols and enes with higher functionality can be UV-cured in combination with petrochemical-based enes or thiols even without the presence of free radical photoinitiators. Better coating film properties were obtained from these higher functionality thiol–ene systems that were toughened by commercial hyperbranched acrylates.
