Environmental-friendly water-based fire extinguishing agent and its preparation method

Abstract

The invention relates to an environmental-friendly water-based fire extinguishing agent, which comprises: deionized water, an antiseptic agent, a metal antirust agent, a halogen-free fire retardant, a hydrocarbon surfactant, a high efficiency chelating agent, 2-5 parts of an osmotic agent and a high efficiency corrosion inhibitor. The preparation method of the water-based fire extinguishing agentconsists of the steps of: adding deionized water into a dispersing cylinder according to the weight part, then adding the antiseptic agent, the metal antirust agent, the halogen-free fire retardant and the hydrocarbon surfactant, and stirring the mixture uniformly till completely salvation of the mixture; then adding the high efficiency chelating agent, the osmotic agent and the high efficiency corrosion inhibitor, stirring them uniformly till semi-clarity, thus obtaining the finished product. Containing a halogen free fire retardant, the fire extinguishing agent of the invention can be biologically degraded 100%, thus having no pollution to surrounding equipment and space. Containing an osmotic agent, the fire extinguishing agent in the invention can penetrate articles in fire hazards ofclass A, and can penetrate into the inside of combustible articles, so that even if the fire is not completely put out due to a large fire, the part injected with the agent can effectively block a fire source and control the spreading speed of a fire. Therefore, the fire extinguishing agent provided in the invention has excellent flame resistance.

Description

technical field [0001] The invention relates to a water-based fire-extinguishing agent and a preparation method thereof, in particular to an environment-friendly water-based fire-extinguishing agent that can replace dry powder in small and medium-sized dry powder fire extinguishers and a preparation method thereof. Background technique [0002] Fire extinguisher is a common small fire extinguishing equipment in modern life. It can be seen in shopping malls, supermarkets, office buildings, homes, and cars. Its structure, size and fire extinguishing principle are also set according to the specific place. The most common ones are dry powder, 1211 fire extinguisher, foam fire extinguisher and carbon dioxide fire extinguisher. In homes or small cars, pressure-storing ABC dry powder high-efficiency fire extinguishers are often equipped, which are small in size, beautiful in appearance, and easy to carry. However, the nozzles are very small and are easily blocked by the deposited ...
