Description
技术领域
本发明涉及织物珠绣用的珠片，尤其是耐水耐磨光致变色或温感变色珠片。
背景技术
珠片广泛用于服装鞋帽、手袋、饰品、工艺品等作为特别的色彩或闪光装饰，织物绣花用珠片跟随织物穿戴，洗涤，因此需要耐水耐磨，其材质通常是高分子聚合物，色彩颜料，光致变色或温感变色功能颜料需添加到珠片片材中与珠片片材一起成型，经分切成为珠片。但这种方式生产批量大，由于珠绣用的珠片色彩需求繁多，成百上千的色彩需求造成产品大量积压，因此需要寻求适合于小批量生产的珠片片材。
发明内容
本发明的目的是提供一种可适合于小批量生产，具有高性能耐水耐磨的光致变色或温感变色珠片。
本发明的珠片具有PET片材和光致变色或温感变色涂层，其制作方法包括如下步骤：
A.配制光致变色或温感变色涂层油墨，按重量百分比的A组分组成和含量为：无油醇酸树酯10—20%，云母钛珠光颜料 5—15%，光致变色或温感变色颜料10—15%，微晶蜡粉5—10%，气相二氧化硅1—5%，氨丙基三乙氧基硅烷0.5—2%，余量为溶剂；将无油醇酸树酯溶于溶剂，加入云母钛珠光颜料，光致变色或温感变色颜料，微晶蜡粉，气相二氧化硅，氨丙基三乙氧基硅烷混合分散制成A组分；二异氰酸酯溶于乙酸乙酯形成二异氰酸酯含量30—70wt%的溶液成为B组分，涂布前A组分和B组分按重量比10:(1—2)比例混合；
B.用涂布机将光致变色或温感变色涂层油墨涂布于PET片材表面，经120—180℃温度干燥后，形成厚度120—250g/M2的涂层，再经40—60℃固化10—40小时，形成珠片片材，珠片片材进一步分切成为耐磨耐水的光致变色或温感变色珠片。
在优选方案中，所述PET片材上相对于光致变色或温感变色涂层的另一表面有透明硫化锌介质层，透明硫化锌介质层有氨基树脂油墨层，氨基树脂油墨层为氨基树脂油墨涂覆形成的涂层，所述氨基树脂油墨按重量百分比，由醇酸树脂0.2—1%，氨基树脂1—5%，醋酸丁酸纤维素树脂1—5%，环氧丙烯酸改性羧酸酯0.1—1%，聚二甲基硅氧烷0.5—2.5%，甲苯磺酰胺0.1—1%，甲醇3—10%，余量为溶剂组成，氨基树脂油墨涂布后经150—220℃干燥固化形成涂布量为3—10g/M2的涂层。
在优选方案中，所述PET片材上相对于光致变色或温感变色涂层的另一表面有紫外线阻隔层，该紫外线阻隔层按重量百分比由醇酸树脂0.2—1%，氨基树脂1—5%，醋酸丁酸纤维素树脂1—5%，环氧丙烯酸改性羧酸酯0.1—1%，聚二甲基硅氧烷0.5—2.5%，甲苯磺酰胺0.1—1%，甲醇3—10%，0.2—3%紫外线吸收剂，余量为溶剂组成的油墨涂覆而成，涂覆后经150—220℃干燥固化，干燥固化涂布量为5—10g/M2。
所述紫外线吸收剂选自苯并三唑紫外线吸收剂，二苯甲酮紫外线吸收剂，三嗪紫外线吸收剂，苯甲酸酯紫外线吸收剂，芳基酯紫外线吸收剂或噁唑啉紫外线吸收剂中的至少一种。
在优选方案中，珠片片材的光致变色或温感变色涂层上涂覆胶黏剂，与另一珠片片材的光致变色或温感变色涂层贴面复合，形成光致变色或温感变色涂层夹于两层PET片材之间的光致变色或温感变色涂层珠片片材。
在优选方案中，所述溶剂选自甲苯，二甲苯，甲基乙基甲酮，乙酸乙酯，乙酸丁酯中的至少一种。
在优选方案中，所述二异氰酸酯选自甲苯二异氰酸酯，异佛尔酮二异氰酸酯，二苯基甲烷二异氰酸酯，二环己基甲烷二异氰酸酯，六亚甲基二异氰酸酯，赖氨酸二异氰酸酯中的至少一种。
本发明珠片的光致变色或温感变色涂层表面硬度达3H，在沸水中煮沸45分钟后无涂层脱落、复合层剥离现象，在烫印温度160℃，烫印时间15秒的情况下烫印无涂层脱落和复合层剥离现像，具有较高的耐水耐磨性能，可以小批量制成珠片片材，适合品种繁多的各种色彩珠片需求。将两个珠片片材的光致变色或温感变色涂层之间进行复合，涂层包覆在两个PET片材之间，可进一步保护光致变色或温感变色涂层，使光致变色温致变色涂层不受水浸泡和摩擦影响。涂层中的光致变色或温感变色颜料可表现出其光致变色或温感变色功能，在不同强度和波长的光照或不同温度下发出变化的色彩。
