Electrical cooling, arc extinguishing and fire extinguishing reagent and preparation method thereof

Abstract

The invention discloses an electrical cooling, arc-extinguishing and fire-extinguishing reagent and a preparation method thereof, and the electrical cooling, arc-extinguishing and fire-extinguishing reagent comprises the following substances in parts by mass: 50-70 parts of perfluorohexanone, 30-50 parts of an organic silicon flame retardant, 20-40 parts of 5, 5-dimethyl-2-chloro-1, 3, 2-dioxo-phosphorus hetero-caprolactone phosphate, 5-12 parts of metal hydroxide, 20-30 parts of graphite powder and 3-5 parts of a dispersing agent. According to the fire extinguishing agent disclosed by the invention, the perfluorohexanone is adopted as a fire extinguishing agent, and the organic silicon flame retardant, the 5, 5-dimethyl-2-chloro-1, 3, 2-dioxo-phosphorus hetero-caprolactone phosphate, the inorganic flame retardant metal hydroxide and the graphite powder with a porous structure are supplemented, so that the problem that after-combustion is easy to occur when the perfluorohexanone fire extinguishing agent is independently applied is solved; and the porous structure of the graphite powder can adsorb HF toxic gas generated in the fire extinguishing process of the perfluorohexanone, so that air pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agent preparation, in particular to an electrical cooling, arc extinguishing, fire extinguishing agent and a preparation method thereof. Background technique [0002] In the prior art, halon fire-extinguishing agents have been banned worldwide because they destroy the atmospheric ozone layer, and perfluorohexanone fire-extinguishing agents have attracted much attention as an efficient, clean and environmentally friendly fire-extinguishing agent. Perfluorohexanone has excellent arc-extinguishing performance and insulation performance, and is mainly used as arc-extinguishing protective gas for frequent operation of power systems and occasions requiring high-speed breaking. It can also be supercharged with nitrogen and stored as part of the fire-extinguishing system. in high pressure gas cylinders. Typical application sites include: fires in computer rooms, data centers, aviation, ships, ...
