Abstract

本发明提供一种热固性树脂成型用薄膜材料，至少含有第一层和第二层，且在23℃下，所述第一层和所述第二层之间存在剥离强度在0.02～30N/cm之间的界面。本发明的热固性树脂成型用薄膜材料具有易于操作、易于移除、不损害模具表面的尺寸精度、在热固性树脂成型后薄膜材料功能层向热固性树脂表面转移，赋予成型品功能性的特点，从而能够改善使用液体脱模剂，所带来的有机溶剂挥发、后续成型体表面打磨带来的粉尘产生与打磨技术难度高、模具经过多次使用后难以保证设计精度等问题。尤其是脱模之后修饰在成型树脂表面的第二层的存在，省去了表面打磨和底涂漆操作步骤，在减少工序、节约工时的情况下，仍能保证面漆的附着能力。
