Ultra-high temperature resistant and self-extinguishing protection structure

Abstract

The invention relates to the technical field of safety protection products, in particular to an ultra-high temperature resistant and self-extinguishing protection structure. The ultra-high temperatureresistant and self-extinguishing protection structure is provided with a self-extinguishing insulation material layer and a silicon carbide fabric layer, wherein the silicon carbide fabric layer is arranged on the self-extinguishing insulation material layer, and a fireproof cotton layer is arranged between the silicon carbide fabric layer and the self-extinguishing insulation material layer; thesilicon carbide fabric layer, the fireproof cotton layer and the self-extinguishing insulation material layer are fixed by stitching or bonding. The ultra-high temperature resistant and self-extinguishing protection structure has reasonable design and simple operation, the silicon carbide fabric has high elastic modulus and high tensile strength, excellent wearing resistance and good high temperature resistance; when a fire occurs, the self-extinguishing insulation material layer in the silicon carbide fabric layer is triggered by temperature sensing so as to spray flame-retardant gas and extinguishing free radicals for extinguishing the fire, and then the fire can be controlled in the area of a protection device to prevent the fire from spreading to the surrounding area; and the protection structure has good extinguishing performance

Description

technical field [0001] The invention relates to the technical field of safety protection products, in particular to an ultra-high temperature resistant self-extinguishing protection structure. Background technique [0002] With the rapid development of power cable buried laying projects, higher requirements are put forward for cable protection. Cables are widely used in many fields, such as large buildings, petrochemicals, subways, factories and urban power networks, etc. Higher requirements are also put forward, among which the fireproof and fire-resistant performance of the power transmission system is very important. It is difficult for existing cables to be fireproof and high temperature resistant, whether it is a power transmission cable or a communication cable. Moreover, existing self-extinguishing insulating materials are only suitable for relatively closed spaces such as electrical cabinets, and it is difficult to meet the gas fire extinguishing concentration requir...

Problems solved by technology

[0002] With the rapid development of power cable buried laying projects, higher requirements are put forward for cable protection. Cables are widely used in many fields, such as large buildings, petrochemicals, subways, factories and urban power networks, etc. Higher requirements are also put forward, among which the fire prevention and fire resistance performance of the power transmission system are very important. It is difficult for existing cables to be fireproof and high temperature resistant, whether it is a power transmission cable or a communication cable.

Moreover, the existing self-extinguishing insulating materials are only suitable for relatively closed spaces such as electrical cabinets, and it is difficult to meet the gas fire extinguishing concentration requirements in open spaces.
