Embodiment 1

[0009] Embodiment 1: a kind of preparation method of the whipping agent of foam fire extinguishing agent, the concrete steps of described method are as follows:

[0010] Step1, add distilled water to dry unfermented cow dung and stir; then remove slag to obtain cow dung filtrate; wherein the mass ratio of dry unfermented cow dung to distilled water is 1:5, and dry unfermented cow dung is used in specific experiments 100g of cow dung;

[0011] Step2. Add NaOH solid to the cow dung filtrate at a ratio of 0.2g / L; stir the prepared solution evenly at 20°C, then put it in a water bath for hydrolysis, and hydrolyze at a water temperature of 20°C for 2 hours. Obtain the cow dung filtrate after high temperature hydrolysis;

[0012] Step3. Cool the cow dung filtrate after high-temperature hydrolysis obtained in Step2 to 20°C, then add foaming agent sodium dodecylbenzenesulfonate to the cooled cow dung filtrate at a ratio of 0.6g / L, and then add The cow dung filtrate after the foaming...

Embodiment 2

[0017] Embodiment 2: a kind of preparation method of the whipping agent of foam fire extinguishing agent, the concrete steps of described method are as follows:

[0018] Step1, add distilled water to dry unfermented cow dung and stir; then remove slag to obtain cow dung filtrate; wherein the mass ratio of dry unfermented cow dung to distilled water is 1:7.5;

[0019] Step2. Add NaOH solid to the cow dung filtrate at a ratio of 0.67g / L; stir the prepared solution evenly at 20°C, then put it in a water bath for hydrolysis, and hydrolyze at a water temperature of 50°C for 2 hours. Obtain the cow dung filtrate after high temperature hydrolysis;

[0020] Step3. Cool the cow dung filtrate after high-temperature hydrolysis obtained in Step2 to 20°C, then add foaming agent sodium dodecylbenzenesulfonate in the cooled cow dung filtrate at a ratio of 0.4g / L, and then add The cow dung filtrate after the foaming agent was stirred in a magnetic stirrer for 5 minutes to make the liquid foa...

Embodiment 3

[0021] Embodiment 3: a kind of preparation method of the whipping agent of foam fire extinguishing agent, the concrete steps of described method are as follows:

[0022] Step1, add distilled water to the dry unfermented cow dung and stir; then remove the slag to obtain the cow dung filtrate; wherein the mass ratio of the dried unfermented cow dung to distilled water is 1:10;

[0023] Step2. Add NaOH solid to the cow dung filtrate at a ratio of 0.3g / L; stir the prepared solution evenly at 25°C, then put it in a water bath for hydrolysis, and hydrolyze it at a water temperature of 80°C for 2 hours. Obtain the cow dung filtrate after high temperature hydrolysis;

[0024] Step3. Cool the cow dung filtrate after high-temperature hydrolysis obtained in Step2 to 25°C, and then add foaming agent sodium dodecylbenzenesulfonate to the cooled cow dung filtrate at a ratio of 0.3g / L, and then add The cow dung filtrate after the foaming agent was stirred in a magnetic stirrer for 10 minute...

Abstract

The invention relates to a preparation method of a foaming agent of a foam extinguishing agent, and belongs to the technical field of environment-friendly materials. The preparation method comprises the steps of: stirring and slag removal, filtration, alkali adding, hydrolysis, cooling and foaming. The foaming agent preparation method is simple, low in cost, easy to realize continuous production, stable in product quality, capable of obtaining more stable foaming agents fast in defoaming, free of polluting the environment, free of generating waste water and capable of realizing the waste recycling; and raw materials are wastes.

Description

technical field [0001] The invention relates to a method for preparing a foaming agent of a foam fire extinguishing agent, and belongs to the technical field of environmental protection materials. Background technique [0002] At present, protein foam fire extinguishing agents are widely used, and are used in many Class A fires. However, the production and application of protein foam fire extinguishing agents will pollute the environment and the raw materials are mostly animal hooves, horns, and feathers. And along with the development of dairy farming, cow dung has become a major problem in environmental pollution and treatment. Therefore, minimizing environmental pollution in the production process and solving the problem of cow dung treatment have always been one of the hotspots that have been widely concerned. Contents of the invention [0003] The invention provides a method for preparing a foaming agent of a foam fire extinguishing agent, which solves the technical ...
