[0024] Preparation method of vegetable protein concentrate:

[0025] (1) Put the rapeseed meal into a pulverizer to grind, pass through a 60-mesh sieve to get the sieved product, mix the sieved product and water according to the mass ratio of 1:4, and stir at 120r / min evenly, Then finely grind it to obtain a fine grind, put the fine grind into a hydrolysis tank, heat up to 50°C under stirring at 200r / min, add cellulase with 1% of the fine grind mass into the hydrolysis tank, Heat preservation and hydrolysis for 1 hour, pass in steam, raise the temperature to 80°C, keep it for 10 minutes, then pass in cooling water, lower the temperature to 40°C to obtain cooling liquid;

[0026] (2) According to the mass ratio of 1:2, the cyclohexane and the cooling liquid were stirred and extracted, and the extraction time was 5 minutes to obtain the extract. The extract was separated in the oil-water separator, and the water phase was collected, and the water phase was separated into Centri...

Abstract

The invention discloses a protein foam extinguishing agent, and belongs to the field of extinguishing agents. A plant protein concentrated solution is prepared from rapeseed dregs; on one hand, the protein is extracted from the plant, so that the problem of pollution to the environment is avoided, and on the other hand, the rapeseed dreg protein has good foamability and foam stability, so that thefoam stability of the foam extinguishing agent is improved; and in addition, thickening agent, namely gelatin is added, so that foam viscosity can be enhanced, a foam drainage speed can be reduced, and then the stability of the foam is enhanced; the gelatin also has a film forming property, and therefore the thickness of a film is enhanced; and moreover, nanometer silicon dioxide is added, the nanometer silicon dioxide has thermal stability, so that the problem of cracking of the film is avoided, and a good fire extinguishing effect is achieved. The protein foam extinguishing agent solves theproblem that a foam extinguishing agent in the prior art is poor in foam stability and the foam is easy to break, so that the sealing performance of the existing foam extinguishing agent is reduced,and the good fire extinguishing effect cannot be achieved.

Description

technical field [0001] The invention belongs to the field of fire extinguishing agents, in particular to a protein foam fire extinguishing agent. Background technique [0002] The occurrence of fire is a serious problem faced by human society. Even in countries with a small population, tens of thousands of fires occur every year, which not only endangers human life and property, but also destroys the environment. When a fire occurs, how to extinguish it quickly and effectively, minimize the loss, the extinguishing ability of the fire extinguishing agent and the method of extinguishing are very important. Foam fire extinguishing agent is an agent that is miscible with water and produces foam through mechanical action or chemical reaction for fire extinguishing. Foam fire extinguishing agent is generally composed of foaming agent, foam stabilizer, viscosity reducer, antifreeze agent, cosolvent, preservative and water. It is mainly used to extinguish non-water-soluble flammabl...
