Thermo-sensitive composite material, as well as preparation method and application thereof

Abstract

The invention relates to a thermo-sensitive composite material, as well as a preparation method and application thereof. The thermo-sensitive composite material is prepared by mixing the following components in percentage by weight: 1-2 percent of high water absorption resin carrier, 5-20 percent of volatile substance, 0-1 percent of emulsifier, and the balance of water, wherein the volatile substance is one of ammonium hydroxide, ethanol, glacial acetic acid and ammonium bicarbonate. The composite material serving as an overheat warning material is applied to an overheat warning system of large power stations and motor distribution cabinets, and has the advantages of normal temperature stable performance, good thermosensitive property, little usage, environmental friendliness, timely and accurate warning and the like.

Description

technical field

[0001] The invention relates to a functional composite material, in particular to a temperature-sensitive composite material which can be used as an alarm medium in an overheat alarm system of electrical equipment. Background technique

[0002] The heating of electrical equipment during operation is a ubiquitous physical phenomenon, and it is also a major safety hazard that affects safe production and stable operation of equipment. In the power distribution cabinets of large power supply systems such as power plants and locomotives, when the connection between the cable output end and the main power supply is loose, the local temperature can reach above 80°C, and even reach above 100°C in severe cases. If the local temperature is too high, it will cause Fires can cause environmental pollution and even endanger human life.

[0003] In order to eliminate such potential safety hazards, temperature-sensitive stickers are generally used to detect the root tempera...
