Problems solved by technology

The most commonly used water-based fire extinguishing agent in the prior art is an aqueous film-forming foam fire extinguishing agent, which is a foam liquid based on hydrocarbon surfactants and fluorocarbon surfactants, which can be used on certain hydrocarbon surfaces A layer of water film is formed on it, which has the characteristics of high efficiency, environmental protection, and long shelf life, but it is expensive; and because once the fluorocarbon surfactant is mixed with seawater, the performance of the fluorocarbon surfactant will become extremely unstable, which is harmful to the foam. The performance and fire extinguishing performance have a great impact, which greatly limits the use of this kind of fire extinguishing agent; and the fire extinguishing agent containing fluorine active agent is not easy to degrade, which poses a threat to the environment

Abstract

The invention relates to the field of fire control and fire extinguishment and particularly relates to a fire extinguishing agent as well as a preparation method and application thereof. The fire extinguishing agent consists of the following ingredients in percentage by weight: 0.5% to 15% of urea, 85% to 99.5% of alkyl glycoside and no water. According to the fire extinguishing agent provided by the invention, the ingredients are reduced and the content of a surfactant is also increased, so the fire extinguishing agent can achieve a higher fire extinguishing speed and has the comprehensive performances of higher efficiency, better environmental protection and lower cost; besides, no water is added in a synthesis process, so the weight of the fire extinguishing agent is reduced, and the fire extinguishing agent can be stored and transported more conveniently.

Description

technical field [0001] The invention relates to the field of fire extinguishing, in particular to a fire extinguishing agent, its preparation method and application. Background technique [0002] Water-based fire extinguishing agent refers to a series of fire extinguishing agents that add additives to fire-fighting water to change the performance of water, thereby improving the fire-extinguishing ability of water, reducing the amount of water used, and expanding the fire-extinguishing range of water. Water-based fire extinguishing agents include enhanced water fire extinguishing agents, wet water fire extinguishing agents, antifreeze water fire extinguishing agents, thickened water fire extinguishing agents, and drag-reducing water fire extinguishing agents. [0003] Water-based fire extinguishing agent is the most widely used fire extinguishing agent because of its low production cost and convenient use. The most commonly used water-based fire extinguishing agent in the pr...
