An environment-friendly flame-retardant antifreeze water-based fire extinguishing agent

Abstract

An environment-friendly flame-retardant antifreeze water-based fire extinguishing agent, the water-based fire extinguishing agent includes the following raw materials in parts by weight: 5-20 parts of fire-extinguishing components, 2-5 parts of EDTA metal salt, 0.5-5 parts of surfactant, and 0.01 parts of water-soluble natural essence ‑0.1 part, 1‑3 part of pentaerythritol, 4.9‑7.8 part of flame retardant, 2‑7.5 part of antifreeze, make up to 100 parts of water. The compounding of pentaerythritol and ethylene glycol and other antifreezing agents of the present invention can effectively achieve the antifreezing effect at a relatively low amount of antifreezing agent; the flame retardant and pentaerythritol can form a non-combustible carbon layer, which can resist backfire and recombustion, and is beneficial to fire extinguishing The inventor also found unexpectedly that adding quantitative sodium ammonium phosphate in the flame retardant can further shorten the average fire extinguishing time of the fire extinguishing agent, the average number of fire extinguishing times and reduce the surface tension of water. The fire extinguishing agent of the present invention is transparent, stable in storage, environment-friendly, low temperature resistant, suitable for extinguishing class A fires and class B fires, and has simple preparation method, cheap and easy-to-obtain raw materials, and is a high-efficiency water-based fire extinguishing agent suitable for large-scale industrial production .

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, and in particular relates to an environment-friendly, flame-retardant, high-efficiency, low-temperature usable water-based fire extinguishing agent. Background technique [0002] With the rapid growth of my country's economy, fires are becoming more and more frequent. How to effectively prevent and control fires has become an important research topic. At present, fire extinguishing agents commonly used at home and abroad are divided into four categories according to their forms: water-based fire extinguishing agents, foam fire extinguishing agents, dry powder fire extinguishing agents, and gaseous fire extinguishing agents. Among them, water-based fire extinguishing agents are the most widely used, mainly for Class A and Class B fires. Water-based fire extinguishing agents use water as the main component, and can enhance the effect of fire extinguishing by adding some chemical ...

Problems solved by technology

[0006] In order to solve the problem of phase separation or inability to store and use water-based fire extinguishing agents in the prior art under low-temperature climate conditions, and to improve the fire-extinguishing and flame-retardant effect, the present invention provides an environmentally friendly flame-retardant, high-efficiency, low-temperature usable water system Fire extinguishing agent, the water-based fire extinguishing agent antifreeze dosage is less than 7.5%, which can achieve a good antifreeze effect (freezing point ≤ -18°C), and then increase the content of flame retardant and fire extinguishing active active ingredients, improve fire extinguishing efficiency, and at the same time store stable layer, friendly to the environment
