中文摘要:
      目的 解决亚克力基材烫印工艺中产生的橘皮、裂纹、糊版等质量问题。方法 利用丝网印刷与热转印相结合的新技术,通过大量的实验及数据分析调整丝网工艺和烫印工艺,确定烫金浆和辅助剂的调配比例,干燥温度和时间,以及烫金温度。结果 实验结果表明,烫金浆、固化剂和稀释剂的质量比为10∶2.5∶1.2时,烫金效果最好,不会出现亚克力烫金箔的橘皮现象;烫金浆的最佳烘干温度为80 ℃,最佳烘干时间为45 min,烘干、烫印温度为130~150 ℃时烫金效果最好,不会出现亚克力烫金箔的裂纹或糊版现象。结论 烫金浆与辅助剂的质量比、烫金浆的干燥温度和干燥时间及烫印温度是决定亚克力烫金质量的关键因素。
英文摘要:
      The work aims to solve such quality problems as peeling, cracking and filling in during the hot stamping process of acrylic substrate. Based on the new technology integrating screen printing and thermal transfer printing, the screen process and stamping process were adjusted, and the mixing proportion of gold stamping pulp and auxiliary agent was determined, the drying temperature and time as well as the temperature of stamping were determined through plenty of experiments and data analyses. The results showed that when the mass ratio of gold stamping pulp, curing agent and diluent was 10∶2.5∶1.2, the effect of hot stamping was the best and no peeling of hot-stamping acrylic foil would occur. The optimal drying temperature of gold stamping pulp was 80 ℃ and the best drying time was 45 minutes. When the temperature of drying and hot stamping was 130~150 ℃, the gold stamping had the best effects and problems like cracking or filling in of hot-stamping acrylic foil would not occur. The mass ratio of gold stamping pulp and auxiliary agent, drying temperature and time as well as stamping temperature of gold stamping pulp are the key factors to determine the hot stamping quality of acrylic substrate.
