Abstract

The invention provides a single-liquid type low-temperature cured special glue for a temperature fuse and a preparation method thereof. The special glue is prepared from the following components in parts by weight: 40-50 parts of bisphenol A type epoxy resin, 5-10 parts of flexible type epoxy resin, 3-8 parts of pigment, 0.5-2 parts of additives, 15-25 parts of curing agents and 20-30 parts of filling. The special glue is cured at low temperature, and does not influence the electrical performance of the fuse due to curing under heating in production process of the fuse. The special glue has the advantages of high flame resistance, low volatility, and high adhesion property.
