Description

一种镭射树脂及其生产工艺
技术领域
本发明涉及一种树脂,尤其涉及一种镭射树脂。
背景技术
BOPP即双向拉伸聚丙烯薄膜,它的生产是将高分子聚丙烯的熔体首先通过狭长机头制成片材或厚膜,然后在专用的拉伸机内,在一定的温度和设定的速度下,同时或分步在垂直的两个方向(纵向、横向)上进行的拉伸,并经过适当的冷却或热处理或特殊的加工(如电晕、涂覆等)制成的薄膜。
该种薄膜的物理稳定性、机械强度、气密封较好,透光性和光泽度较高,坚韧耐磨,是目前应用较广泛的印刷薄膜。但其主要缺点是热封性差,所以一般用做复合薄膜的外层薄膜,由于双向拉伸聚丙烯薄膜的表面为非极性,结晶度高,表面自由能低,因此,其印刷性能较差,对油墨和胶黏剂的附着力差,在印刷和复合前需要进行表面处理。
发明内容
本发明的内容是提供一种镭射树脂,其能够克服现有技术的某种或某些缺陷。
一种镭射树脂,按照质量百分比包括以下组分:醋酸丁酸纤维素4%,松香9%,附着力促进剂2%,增塑剂2-2.5%,丁酯40%,正丁醇5%,其余为乙酯。
作为优选,附着力促进剂包括氯化聚丙烯50%,丙烯酸树脂30%,丁酯20%。
一种镭射树脂的制作工艺,其包括以下步骤:
步骤一、制备附着力促进剂,称取质量百分为50%的氯化聚丙烯,30%的丙烯酸树脂以及20%的丁酯放入密封容器内加热搅拌,加热温度为100℃并保温1h;
步骤二、按照权利要求1中的质量百分比称取各个组分;
步骤三、将步骤二中称取好的松香和丁酯的一部分混合搅拌至完全松香溶解,得到浓度为30%的松香溶液;
步骤四、将步骤二中称取好的醋酸丁酸纤维素和剩余的丁酯混合搅拌至醋酸丁酸纤维素完全溶解,得到浓度为15%的醋酸丁酸纤维素溶液;
步骤五、将步骤一中得到的附着力促进剂、步骤三中得到松香溶液以及步骤四中得到的醋酸丁酸纤维素溶液混合,再混合步骤二中称取好的剩余组分混合搅拌至完全溶解;
步骤六、密封保存。
作为优选,在密封保存前还加入色粉调色。
具体实施方式
为进一步了解本发明的内容,结合实施例对本发明作详细描述。应当理解的是,实施例仅仅是对本发明进行解释而并非限定。
实施例1
一种镭射树脂,按照质量百分比包括以下组分:醋酸丁酸纤维素4%,松香9%,附着力促进剂2%,增塑剂2%,丁酯40%,正丁醇5%,乙酯38%。
其中,附着力促进剂包括氯化聚丙烯50%,丙烯酸树脂30%,丁酯20%。本实施例中在镭射树脂的配方内加入了由氯化聚丙烯、丙烯酸树脂和丁酯按照特定配比制得的附着力促进剂,其能够有效改善双向拉伸聚丙烯薄膜的附着力。
另外,在镭射树脂的配方中采用松香来提高亮度,改善花纹的镭射效果,并且用醋酸丁酸纤维素来对松香进行干燥,使得松香的使用效果更佳。
本实施例中的增塑剂采用市面上常规的增塑剂,其能够增强镭射树脂的可塑性。
本实施例中镭射树脂配方中溶剂并非单一组分,而是采用丁酯、正丁醇、以及乙酯通过特定的配比得到,由于丁酯、正丁醇、以及乙酯具有不同的沸点,因而其在混合使用时能够使得镭射树脂涂覆于双向拉伸聚丙烯薄膜上后能够更加快速的干,增强镭射树脂的使用效果。
实施例2
一种镭射树脂,按照质量百分比包括以下组分:醋酸丁酸纤维素4%,松香9%,附着力促进剂2%,增塑剂2.5%,丁酯40%,正丁醇5%,乙酯37.5%。
其中,附着力促进剂包括氯化聚丙烯50%,丙烯酸树脂30%,丁酯20%。
实施例3
一种镭射树脂的制作工艺,其包括以下步骤:
步骤一、制备附着力促进剂,称取质量百分为50%的氯化聚丙烯,30%的丙烯酸树脂以及20%的丁酯放入密封容器内加热搅拌,加热温度为100℃并保温1h;
步骤二、按照实施例1或实施例2中给出的各个组分的质量百分比称取各个组分;
步骤三、将步骤二中称取好的松香和丁酯的一部分混合搅拌至完全松香溶解,得到浓度为30%的松香溶液;
步骤四、将步骤二中称取好的醋酸丁酸纤维素和剩余的丁酯混合搅拌至醋酸丁酸纤维素完全溶解,得到浓度为15%的醋酸丁酸纤维素溶液;
步骤五、将步骤一中得到的附着力促进剂、步骤三中得到松香溶液以及步骤四中得到的醋酸丁酸纤维素溶液混合,再混合步骤二中称取好的剩余组分混合搅拌至完全溶解;加入色粉进行调色。
步骤六、密封保存。
使用时,将制得的镭射树脂加热到80-100℃并均匀涂于难附着的双向拉伸聚丙烯薄膜上,采用模具压花,最后自然冷却得到成品。涂覆了镭射树脂的双向拉伸聚丙烯薄膜的印刷性能能够得到明显的改善,对油墨和胶黏剂的附着力得到有效的提高,在印刷和复合前只需进行很简单的表面处理甚至无需进行表面处理。
以上示意性的对本发明及其实施方式进行了描述,该描述没有限制性。所以,如果本领域的普通技术人员受其启示,在不脱离本发明创造宗旨的情况下,不经创造性的设计出与该技术方案相似的方式及实施例,均应属于本发明的保护范围。
