Abstract

The invention relates to the technical field of chemistry, in particular to a perlite type dry powder fire extinguishing agent and a preparation method thereof. The fire extinguishing agent comprises the following raw materials in parts by mass: 10-20 parts of perlite, 45-50 parts of ammonium sulfate, 30-40 parts of sodium chloride and 6-15 parts of white carbon black. The perlite type dry powder fire extinguishing agent has the beneficial effects that the provided perlite type dry powder fire extinguishing agent is environment-friendly and non-combustible in raw materials, small and uniform in product granularity, high in thermal stability, good in ultraviolet absorbability, good in hydrophobicity and suitable for liquid fire situations.

Description

Technical field [0001] The present invention relates to the field of chemical techniques, and more particularly to pearl rock type dry powder fire extinguishing agents and preparation methods thereof. Background technique [0002] Dry powder extinguishing agent is currently using the most widely used solid fire extinguishing agent in the market, composed of one or more subtle inorganic powders with fire extinguishing capacity, spraying the fire extinguishing agent and covers the surface of the flammable material, blocking the flammable Oxygen in the air contacts, so that the burning cannot be maintained and extinguished to realize fire extinguishing function. [0003] In the prior art, there is a lot of performance and use disadvantages, such as the low melting point, weak to liquid fire, etc. Inventive content [0004] The primary object of the present invention is to provide a pearl rock type dry powder fire extinguishing agent, including the following mass parts: 10-20 perlit...
