Thermosensitive wire and preparation method thereof

Abstract

The invention provides a thermosensitive wire and a preparation method thereof. The preparation method comprises the steps that a temperature-sensitive combustible agent, a stabilizing agent, a flameinhibitor, a performance modifier and a solvent are mixed and plasticized, the mixture is pressed into a medicine strip after being plasticized, and the medicine strip is cut and dried after being dried in the air. The thermosensitive wire prepared by the invention can be started in a rated temperature range; when the temperature of the surface of the thermosensitive wire reaches 170-180 DEG C andthe heating duration exceeds 10 seconds, the thermosensitive wire can be automatically started, the false touch rate is low under normal conditions, and the thermosensitive wire has excellent moisture resistance, small combustion smoke and small flame, belongs to an environment-friendly moisture-proof lead, and is simple and convenient in production process.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a thermal wire activated as an intelligent fire extinguishing material integrated device and a preparation method thereof. Background technique [0002] Aerosol fire extinguishing agent is a new type of fire extinguishing agent. It produces a large amount of fire extinguishing smoke through redox reaction for total flooding fire extinguishing. It has many advantages such as environmental protection, rapid fire extinguishing, and cheap price. It is especially suitable for electrical fires in relatively confined spaces. , such as power distribution cabinets, electrical cabinets, electric boards, air-conditioning cabinets and other small spaces. However, since the trigger temperature of the redox reaction of the aerosol fire extinguishing agent is 400°C-500°C, the trigger temperature is too high. When a fire occurs, the fire extinguishing reaction cannot be start...

AI Technical Summary

Problems solved by technology

It is very important to start the aerosol fire extinguishing agent quickly by adding a thermal line, which is extremely important in the early stage of a fire. Traditional fuses are mostly used for fireworks and firecrackers, and there are many types, mostly leather paper, cotton yarn, safety, fast, and slow. etc., its structure is generally cotton yarn or paper wrapped lead medicine, which plays the role of ignition and fire transmission, but the manufacturing process is complicated, and most lead medicines contain sulfur, alloys, etc., which will pollute the environment and affect people's health. There are also a large number of nitrocellulose-based fuse processes, but most of the processes are more complicated, and they are also prone to moisture in rainy days, which affects the ignition and fire transmission effects.
