摘　　要：为了研究光引发剂对UV柔印油墨稳定性的影响,使用3种光引发剂制备UV柔印品红油墨样品,对光引发剂种类对油墨稳定性的影响进行了研究。通过改变光引发剂907的含量制备油墨样品,研究了光引发剂含量对油墨稳定性的影响。结果表明,光引发剂种类及含量对UV柔印油墨稳定性有很大影响,主要影响油墨的黏度和固化速度。光引发剂TPO所制备的油墨具有较好的储存稳定性;光引发剂907用量为8%时,油墨能保持较好的黏度稳定性,且具有最高的固化速度。In this experiment, three kinds of photo initiators are used to obtain different samples of UV flexo ink, thus investigated the influence of photo initiator type on ink stability. Then through changing the amount of photo initiator 907 in ink samples, the affection of the photo initiator amount upon ink stability is investigated. The results show that the type and amount of photo initiator has an impact on the stability of UV flexo inks, mainly affection the ink viscosity and curing speed. The ink used photo initiator TPO has good storage stability; the ink could maintain good viscosity stability, and reached the highest cure rate when the amount of 907 photo initiator is 8%.
