Thermosensitive phase change protective film, preparation method thereof and laminated ceramic capacitor

LI SHIHE

The invention provides a thermosensitive phase change protective film and a preparation method thereof. The thermosensitive phase change protective film comprises a release film layer, a thermosensitive phase change layer and a supporting film layer which are arranged in a stacked mode, wherein the thermosensitive phase change layer comprises a matrix adhesive layer and thermosensitive phase change capsules dispersed in the matrix adhesive layer, and each thermosensitive phase change capsule comprises a shell and phase change particles located in the shell. By selecting the phase change particles with proper phase change temperature, the debonding temperature of the thermosensitive phase change protective film can be increased.

本申请提供了一种热敏相变化保护膜及其制备方法，包括：层叠设置的离型膜层、热敏相变化层和支撑薄膜层；其中，热敏相变化层包括基体胶层以及分散于基体胶层内的热敏相变化胶囊，热敏相变化胶囊包括壳体以及位于壳体内部的相变化颗粒。通过选择合适相变化温度的相变化颗粒可以提高热敏相变化保护膜的解粘温度。
