所述特氟龙层包括以下重量份的成分组成：

对比例1
与实施例3基本相同，区别在于未使用三羟甲基丙烷三丙烯酸酯。
对比例2
与实施例3基本相同，区别在于未使用双酚A型环氧丙烯酸酯。
对比例3
与实施例3基本相同，区别在于未使用三羟甲基丙烷三丙烯酸酯和双酚A型环氧丙烯酸酯。
在50-70℃的恒温条件下对制得的特氟龙彩色玻纤布胶带进行紫外线照射，观察其颜色变化，结果如表1
可见，本实施例制得的特氟龙彩色玻纤布胶带在高温情况下无变色沉淀现象。其原因在于双酚A型环氧丙烯酸酯分子中的双键密度高，随着双酚A型环氧丙烯酸酯在齐聚物中的含量的增加，涂膜中的交联度变大，颜料的迁移性变大小，涂膜的耐迁移性变高；且三羟甲基丙烷三丙烯酸酯是三官能度单体，既是稀释剂，又是交联剂，能使涂膜中形成三维网状结构，并且其用量越多，涂膜的交联度越大，涂膜的耐迁移性越好。
最后需要说明的是：以上所述仅为本发明的较佳实施例，仅用于说明本发明的技术方案，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所做的任何修改、等同替换、改进等，均包含在本发明的保护范围内。
