Description
技术领域
本发明涉及文化产品印刷新材料及其制备技术领域，特别涉及一种抗菌耐腐蚀热转印花膜及其生产工艺。
背景技术
热转印花膜广泛应用于文具、玩具、竹木、五金、玻璃、金属、日用品、化妆品等领域。具体地，热转印花膜是指带有胶黏剂的图文，在热与压力的共同作用下，连同离型层一起脱离载体薄膜，牢固转印在承印物表面的特殊功能印刷膜。热转印膜一般由3～5层构成。三层热转印膜由基底层、印刷层和胶黏层构成；四层热转印膜由基底层、离型层、印刷层和胶黏层构成；五层热转印膜由基底层、离型层、印刷层、胶黏层和热熔胶粉层构成。基底层：即离型剂、油墨及胶黏剂涂布的载体，要求该载体耐温、耐压、拉伸变形小。离型层：是一层离型剂的涂层，在常温下保持固体状态，在一定的温度下可熔化，与基底层的粘结力变小，能很快从基底层上脱离，无粘连剩余物。离型剂是完成印刷层从基底层上分离，向承印物表面转移的关键。它要求具有良好的耐磨性，起到保护彩色油墨，降低紫外线的辐射强度，降低空气中不利因素对油墨的侵袭，延长油墨使用期的作用，并能缓冲基材薄膜和印刷层的附着力。印刷层：该层是转印制品质地美感的根本。随着印刷技术的进步、图像处理技术的发展，印刷层具有各种色泽，各种图案。特别是采用凹版印刷得到的图文，能很好体现出细腻的图文，让其包装装饰效果更完美。胶黏层：它的基本性能是与承印物表面有较高的粘结力，保证印刷层与承印物表面结合牢固。该层胶黏剂必须与承印材料相匹配。不同的胶黏剂，由于化学成分的不同，与承印物的粘结力相差很远。应根据不同的承印物，进行选择。目前所有的热转印花膜在使用时，要确保承印物表面无白点、脏污、条痕等弊病，否则会影响整个印花膜的性能，如美观性、耐候性、耐刮性、热断裂性、重叠性等，承印物表面不明显的污点，也会明显影响热转印花膜的性能，导致产生霉菌发霉；另外，热转印花膜的耐磨性，一定程度上决定其使用寿命。因此，研制一种抗菌耐腐蚀热转印花膜可以避免上述问题，增加热转印花膜的美观性、延长其使用寿命。
发明内容
发明的目的：本发明的目的在于提供一种抗菌耐腐蚀热转印花膜及其生产工艺。
