Abstract

A color-change indication thermosetting glue / conductive adhesive comprises resin and a thermosensitive color-change material which is an irreversible thermosensitive color-change material, the range of the curing temperature H of the epoxy resin is H1-H2, and the color-change temperature of the thermosensitive color-change material is L, wherein H1<=L<=H2. The color-change indication thermosettingglue / conductive adhesive is subjected to color change when the curing temperature is L so as to visually, rapidly and preliminarily determine whether the color-change indication thermosetting glue / conductive adhesive is completely cured or not.

Description

technical field

[0001] The invention relates to a color-changing indicating thermosetting glue and a color-changing indicating thermosetting conductive adhesive. Background technique

[0002] Generally, after the thermosetting glue / conductive adhesive is cured, it must go through a series of functional tests (such as adhesion test, hardness test, UV-DSC detection) before it can be judged whether it is cured, that is to say, the existing thermosetting glue / conductive adhesive The curing degree cannot be known immediately after curing, and the analysis of the curing degree faces defects such as time lag and complicated detection process. Contents of the invention

[0003] In view of this, it is necessary to provide a color change indicating thermosetting adhesive / conductive adhesive, which changes color when fully cured.

[0004] A color-changing indicating thermosetting glue, comprising epoxy resin, hardener, accelerator, anti-settling agent and heat-sensitive color-changi...
