Abstract

The invention provides a temperature sensing material with negative temperature coefficient effect and method for preparing process, wherein the NTC material comprises polymer, temperature-sensitive organic-inorganic composite powder and auxiliary agent, wherein the temperature on certain spot of the temperature-sensitive material changes, the resistance will be lowered substantially, thus the value of resistance of the detecting circuit will be changed greatly. The conductivity process of the temperature-sensitive material is realized through carrier supply by the temperature-sensitive organic-inorganic composite powder.

Description

technical field

[0001] The invention relates to the technical fields of chemical industry and electronics, in particular to a temperature-sensing material with a negative temperature coefficient effect (NTC) and a preparation method thereof. The temperature range of this temperature-sensing material is 0-250°C, and it can be used as a recoverable alarm cable, temperature-sensing detector, equipment overheating protection device, temperature controller, etc. Background technique

[0002] General temperature monitoring components such as thermocouples, platinum resistors, and ceramic thermistors can only measure the temperature in a narrow area (which can be abstracted as a point). In some occasions (such as large buildings, rainy, foggy and sandy open-air environments, various industrial sites, flammable and explosive dangerous places, protective tunnels, cables, conveyor belts, various pipelines, etc.), it is necessary to perform a larger second Temperature monitoring in th...
