A kind of composite plant protein foam fire extinguishing agent and preparation method thereof

Abstract

The invention provides a composite type plant protein foam extinguishing agent. The composite type plant protein foam extinguishing agent is prepared from, by weight, 70-90 parts of a vinasse protein hydrolysate concentrated solution, 6-20 parts of vinasse powder, 1-7 parts of a foam stabilizing agent, 1-2.5 parts of an organic solvent and 0.1-0.5 parts of preservatives. According to the composite type plant protein foam extinguishing agent, on the basis of the principle that the strength of a foam framework is enhanced through solid particles, the vinasse powder is introduced in the protein foam extinguishing agent, and remaining residues after vinasse hydrolysis is reduced or the effective utilization rate of the vinasse powder is increased; and the high temperature carbonizing characteristic of vinasse plant fibers is utilized, the anti-burning performance of the foam extinguishing agent is improved, and a good synergetic enhancement extinguishing effect is achieved. The invention further provides a preparation method of the composite type plant protein foam extinguishing agent. The problems that in the preparing and combusting process of an animal protein foam extinguishing agent, foul gas is released, and the environment is polluted are solved, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and in particular relates to a composite vegetable protein foam fire extinguishing agent and a preparation method thereof. Background technique [0002] Protein foam fire extinguishing agent has good thermal stability and good fluidity, and can quickly form a covering layer on the surface of water-insoluble liquids, and is widely used in the fire fighting of various petroleum products, oils and other water-insoluble flammable liquids , is currently one of the fire extinguishing agents with the largest production volume and the widest application range in my country. [0003] The main components of protein foam fire extinguishing agent are biochemical substances such as protein and sugar, and it is currently the only pure natural and environment-friendly foam fire extinguishing agent that can be 100% biodegradable. At present, the protein foam fire extinguishing agent produced in China is mainly...

AI Technical Summary

Problems solved by technology

At present, the protein foam fire extinguishing agent produced in China is mainly animal protein type. The protein is made of animal hair, hooves, horns, etc. through acid or alkali hydrolysis. During the process, a large amount of malodorous gas containing mercaptan, sulfide, and thiohydrogen will be produced, which will bring some inconvenience to the use; and the vegetable protein foam fire extinguishing agent can avoid the pollution during the production of animal protein foam fire extinguishing agent and the generation of fire extinguishing. Disadvantages of bad smell, and it can overcome the corrosion of chemical foam fire extinguishing agents to related objects in the fire extinguishing place and the pollution to the environment

[0004] However, at present, plant protein foam fire extinguishing agents are mainly processed by hydrolysis of raw materials such as bean cake, rapeseed cake, peanut cake, and rice dregs. However, the lack of domestic feed protein sources leads to high prices, and its application is limited.
