Embodiment 1

[0033] The component of present embodiment multifunctional foam fire extinguishing agent is as follows (mass percentage):

[0034] Carob gum: 0.5%

[0035] Chitosan: 0.5%

[0036] Hydrocarbon Surfactant: 10% (Sodium Lauryl Sulfate, AOS)

[0037] Special surfactant: 3% (fluorosulfonic acid acyl quaternary ammonium iodine compound, potassium fluorosulfonate)

[0038] Antifreeze: 12% (butyl carbitol)

[0039] Preservatives: 0.3% (Lauryl Dimethyl Ammonium Bromide)

[0040] water: balance

[0041] The preparation method of this embodiment is: calculated by mass percentage, at room temperature, first take 50% of water and stir, first slowly add the above-mentioned carob bean gum and chitosan, and then add the hydrocarbon surfactant , After making it completely dissolved, add antifreeze, after it dissolves well, add special surfactant, after it dissolves evenly, add preservative, add water to 100% and stir for 2 hours. (The above steps are all carried out while stirring).

Embodiment 2

[0043] The component of present embodiment multifunctional foam fire extinguishing agent is as follows (mass percentage):

[0044] Locust bean gum: 0.7%

[0045] Chitin: 0.8%

Abstract

The present invention provides one kind of high efficiency multipurpose foam extinguishant and its preparation process. The multipurpose foam extinguishant consists of water, protecting colloid 1-2 wt%, foaming agent 5-10 wt%, fireproof filming agent 0.5-3 wt% and water for the rest. The protecting colloid is natural plant polysaccharide, chitin and its derivative; the foaming agent includes several kinds of hydrocarbon surfactants; and the fireproof filming agent includes several kinds of special surfactants. The multipurpose foam extinguishant is prepared through mixing the said components, and the preparation process is simple, high in efficiency, environment friendly and power saving. The multipurpose foam extinguishant may be applied to replace available foam extinguishants and may be used with various kinds of available foam extinguishing apparatus.

Description

technical field [0001] The invention relates to the technical field of chemistry, and in particular designs a multipurpose foam fire extinguishing agent and a preparation method thereof. technical background [0002] Atmospheric ozone layer is constantly being destroyed, and the world is paying attention to it. Foam fire extinguishing agent is the first product recommended by the United Nations to replace halon fire extinguishing agent, and our country also attaches great importance to it. At present, most of the domestic and foreign markets are occupied by "protein foam fire extinguishing agents", and its production not only consumes energy and water, but also seriously pollutes the environment with three wastes, and its fire extinguishing efficiency is not very high. Petroleum resources are non-renewable, and the energy crisis has become an important factor affecting the development of the world economy. Our country and countries all over the world are developing oleyl-al...
