【摘要】 在配方实验中,用UV-2700测定颜料和光引发剂的紫外透射光谱图,找出颜料的透光窗口和光引发剂的吸收峰值,匹配出互不干扰紫外吸收的颜料和光引发剂,再在后期的性能测定实验中确定颜料和光引发剂的种类和比重;运用混合均匀设计法,以达到D95范围内最小的粒径为指标,确定单体、分散剂、消泡剂和分散树脂的最优配比;配置出色浆后,运用正交试验设计方法,以粘度、表面张力、固化速度、附着强度和色密度为指标,确定色浆、光引发剂、成膜树脂、助剂等的配比方案,最终优选出达到指标要求的C色UV喷墨油墨的配方。更多还原

【Abstract】 UV spectrophotometer was used to measure UV transmittance spectrum of pigment and photo-initiators to identify the light transmitting window of a pigment and photo-initiators’ absorption peak,then later the types of photo-initiators was determined.In order to determine the optimal assignment of monomers,dispersing agent,defoaming agent and dispersing resin,the uniform design method was supplied to achieve the smallest particle diameter within the range of D95.After the excellent configuration of based ink,the orthogonal design method was used to determine the proportion of based ink,photo-initiators,film-forming resin,additives by regarding viscosity,surface tension,curing speed,and color fastness as indicators.更多还原
