Abstract

The invention discloses a halogen-free flame-retardant extinguishing agent, which is characterized by comprising the following components in percentage by weight: 10-40% of water, 20-50% of phosphorous compound, 10-30% of boric compound, 5-10% of tetrakis hydroxymethyl phosphonium sulfate, 5-15% of phosphorylated castor oil, 5-12% of zinc oxide, and 0.5-5% of surface active agent, preferably, 35-48% of the phosphorous compound and 17-26% of boric compound. The halogen-free flame-retardant extinguishing agent disclosed by the invention has the advantages that raw materials are cheap and easily obtained, the cost is low, pollution is not generated, the seepage force of products is strong, open fire can be extinguished only by simply spraying and sprinkling, and extinguishment can be up to the B1 level.

Description

technical field [0001] The invention relates to a halogen-free flame retardant fire extinguishing agent. Background technique [0002] At present, the commonly used fire extinguishing agents mainly include water, foam fire extinguishing agent, halogenated alkane fire extinguishing agent, carbon dioxide fire extinguishing agent, dry powder fire extinguishing agent and so on. Different fire extinguishing agents have different characteristics and performances. Water is the most widely used natural fire extinguishing agent. It can be used alone or in mixture with different chemical agents. Among the existing fire-fighting equipment, water extinguishing accounts for a large proportion. Water can chemically react with many substances, such as active metals, metal hydrides, alkali metal carbides, silicon metal compounds, phosphides, boron hydrogen substances, etc., to produce flammable gases and release a certain amount of heat at the same time. When the temperature reach...
