Problems solved by technology

[0011] Most of these patents add a foaming agent to the water to cover the burning surface of the article to a certain extent, and some will slow down the fluidity of the water-based fire extinguishing agent through a thickener and prolong the flame retardant time; but the thickener will Increase the viscosity of the water-based fire extinguishing agent, which is not conducive to the flow of foam, and the moisture content of the foam is relatively small
Without adding thickener, the fluidity of water-based fire extinguishing agent is too good, and it is easy to cause waste

Embodiment 19

[0085] Water-based fire extinguishing agent, the difference between Example 19 and Example 16 is that 8 parts of C8-16 alkyl glycosides are used instead of 8 parts of D-glucopyranose decyl octyl glycoside oligomer. The fluidity and viscosity of Example 19 are not significantly different from those of Example 16 after testing.

Embodiment 20

[0087] Water-based fire extinguishing agent, the difference between Example 20 and Example 16 is that 8 parts of dodecyl glucoside are used instead of 8 parts of D-glucopyranose decyl octyl glycoside oligomer. The fluidity and viscosity of Example 20 are not significantly different from those of Example 16 after testing.

Embodiment 17

[0105] In Example 17, the amount of xanthan gum increases, which improves the viscosity of the fire extinguishing agent and reduces the fluidity of the fire extinguishing agent. Although it is beneficial to generate a thicker covering layer on the burning surface and the isolation effect is better, the fluidity and diffusion The degree is reduced, and the utilization rate of fire extinguishing agent is also reduced.

Abstract

The invention relates to the field of fire extinguishing agents, in particular to a water-based fire extinguishing agent. According to the technical scheme, the water-based fire extinguishing agent is characterized by comprising following components including, by weight, 10-24 parts of a foaming agent, 3-8 parts of a foam stabilizer, 0.5-1.5 parts of a tempering agent and 0.5-2 parts of a thickening agent, and water dissolving the above components is further included. By usage of the above formula, the surface tension of the fire extinguishing agent is controlled to be below 30 mM / m, and the requirement of A type fire extinguishing agents can be well met.

Description

technical field [0001] The invention relates to the field of fire extinguishing agents, more specifically, it relates to water-based fire extinguishing agents. Background technique [0002] Fire extinguishing agent refers to the substance that can effectively destroy the combustion conditions and terminate the combustion; the fire extinguishing mechanism is mainly: cooling, suffocation, isolation and chemical suppression. According to its state characteristics, it can be divided into three categories: liquid fire extinguishing agent, solid fire extinguishing agent and gas fire extinguishing agent. [0003] The halon fire extinguishing agent in the gaseous fire extinguishing agent has the characteristics of fast fire extinguishing speed, can extinguish the flame in a very short time, and has the characteristics of small dosage, easy gasification, and non-conductivity. It has been used all over the world since it came out. However, the halon fire extinguishing agent contains ...
