Description

耐高温美纹纸胶带的制备工艺
技术领域
本发明涉及一种胶带的制备工艺，具体涉及的是耐高温美纹纸胶带的制备工艺。
背景技术
胶带是日常生活和工作中常用的固定和遮蔽的工具之一，按功效可分为高温胶带、中温胶带、常温胶带、双面胶带、绝缘胶带、特种胶带、压敏胶带、模切胶带等等，根据不同的功效适用于不同的场所和领域，其中高温胶带又是常用的胶带之一。
纸胶带主要应用在喷涂方面，为了保护其他表面不被涂料污染，施工前需要先用胶带把喷涂位置的边缘进行覆盖，使得涂料不会污染其他表面。由于施工物体的表面温度可能较高，而且户外阳光暴晒时升温也容易使得美纹纸胶带失去固有的粘性，影响喷涂施工的效果。
现有纸胶带相较于一般胶带，表面改为纸，通常黏性不强、抗拉力不高，耐高温的性能也不佳，也常常出现在高温条件下脱胶的情况发生。
发明内容
本发明的目的在于解决纸胶带相较于一般胶带黏性不强，耐高温的性能也不佳的问题，提供一种解决上述问题的耐高温美纹纸胶带的制备工艺。
为解决上述缺点，本发明的技术方案如下：
耐高温美纹纸胶带的制备工艺，包括：
（1）将离型剂层复合到纸基材层上；
（2）制备胶粘剂层：将过氧化二苯甲酰溶解到溶剂中，再将其与有机硅压敏胶水混合均匀制成混合胶一；将过二异氰酸酯溶解到溶剂中，再将其与丙烯酸酯压敏胶水混合均匀制成混合胶二；将聚甲基三乙氧基硅烷溶解到溶剂中，再将其与硅酮胶混合均匀制成混合胶三；顺次将混合胶二和混合胶一添加到混合胶三中，混合均匀后制成胶粘剂层；
（3）最后将胶粘剂层附着在纸基材层上即制成成品；
所述纸基材层由美纹纸组成，所述胶粘剂层由以下重量份的组分组成：
过氧化二苯甲酰1～3份，有机硅压敏胶水90～100份，二异氰酸酯1～4份，丙烯酸酯压敏胶水200～210份，硅酮胶50～60份，聚甲基三乙氧基硅烷1～3份。
进一步，所述胶粘剂层由以下重量份的组分组成：
过氧化二苯甲酰1～2份，有机硅压敏胶水95～100份，二异氰酸酯2～4份，丙烯酸酯压敏胶水200～205份，硅酮胶55～60份，聚甲基三乙氧基硅烷2～3份。
进一步，所述胶粘剂层由以下重量份的组分组成：
过氧化二苯甲酰2份，有机硅压敏胶水95份，二异氰酸酯3份，丙烯酸酯压敏胶水205份，硅酮胶60份，聚甲基三乙氧基硅烷2份。
本发明与现有技术相比，具有以下优点及有益效果：
本发明制备出的胶带抗拉力、粘着力、耐热性均较高，且在该配比下，本发明在长时间的高温条件下，粘着力也极佳，不会出现脱胶的情况，同时在高温条件下的长时间粘附后也不会出现残胶的情况，效果十分显著。
具体实施方式
下面结合实施例对本发明作进一步地详细说明，但本发明的实施方式不限于此。
