Embodiment 1

[0021] (1) The dried animal hairs with 100 parts by mass are pulverized with a high-speed pulverizer until the chicken feathers are crushed to an average particle size lower than 5 mm, then 4 parts of protease and 800 parts of tap water are added, After high-speed stirring, the mixed liquid was obtained, and then sealed and fermented at 55°C for 5 days, then left to cool, filtered with a 800-mesh filter to obtain the filtrate, and concentrated under reduced pressure at 35°C to the volume of the original liquid 1 / 4-1 / 3 of that, this substance is the hair solution.

[0022] (2) Add 25 parts of amphoteric surfactant, 15 parts of nonionic surfactant, and 50 parts of hair solution into the reaction kettle, stir and mix at a high speed, and obtain a foam forming agent after mixing evenly.

[0023] (3) 25 parts by mass of ethylene glycol, 6 parts of propylene glycol, and 8 parts of glycerol are added into the reaction kettle for stirring, and what is obtained after stirring evenly is...

Embodiment 2

[0028] (1) The dried animal hair of 110 parts by mass is pulverized with a high-speed pulverizer until the chicken feathers are crushed to an average particle size lower than 5mm, then 4 parts of protease and 600 parts of tap water are added, After high-speed stirring, the mixed liquid was obtained, and then sealed and fermented at 55°C for 3 days, then left to cool, filtered with a 800-mesh filter to obtain the filtrate, and concentrated under reduced pressure at 35°C to the volume of the original liquid 1 / 4-1 / 3 of that, this substance is the hair solution.

[0029] (2) Add 24 parts of amphoteric surfactants, 16 parts of nonionic surfactants, and 45 parts of hair solution into the reaction kettle, stir and mix at a high speed, and obtain a foam forming agent after mixing evenly.

[0030] (3) 26 parts by mass of ethylene glycol, 5 parts of propylene glycol, and 7 parts of glycerol were added into the reaction kettle for stirring, and what was obtained after stirring evenly was...

Embodiment 3

[0035](1) The dried animal hair of 120 parts by mass is pulverized with a high-speed pulverizer until the chicken feathers are crushed to an average particle size lower than 5 mm, then 5 parts of protease and 1000 parts of tap water are added, After high-speed stirring, the mixed liquid was obtained, and then sealed and fermented at 55°C for 5 days, left to cool, filtered with a 800-mesh filter to obtain the filtrate, and concentrated under reduced pressure at 30°C to the volume of the original liquid 1 / 4-1 / 3 of that, this substance is the hair solution.

[0036] (2) Add 30 parts of amphoteric surfactants, 20 parts of nonionic surfactants, and 60 parts of hair solution into the reaction kettle, perform high-speed stirring and mixing, and obtain a foam forming agent after mixing evenly.

[0037] (3) Add 30 parts by mass of ethylene glycol, 8 parts of propylene glycol, and 10 parts of glycerol into the reaction kettle for stirring, and what is obtained after stirring evenly is a...

Abstract

The invention relates to the field of fire fighting and extinguishing materials, in particular to a protein type biological fire extinguishing agent, and in particular to a biological fire extinguishing agent using animal hair as a raw material. The biological fire extinguishing agent comprise, by mass, 60-80 parts of a hair dissolving solution, 2-3 parts of a flame retarding agent, 6-12 parts ofmodified starch, 15-20 parts of a foam forming agent, 8-14 parts of a stabilizing agent and 1-2 parts of a preservative. The biological fire extinguishing agent has biodegradability and a good foam forming characteristic, is high in viscosity and good in adhesiveness, and can be widely applied in recuing of various types of A type fire disasters and B type fire disasters.

Description

technical field [0001] The invention relates to the field of fire extinguishing materials, in particular to a protein-based biological fire extinguishing agent, in particular to a biological fire extinguishing agent using animal hair as a raw material. Background technique [0002] Fire extinguishing agents can be divided into liquid extinguishing agents, solid extinguishing agents and gas extinguishing agents according to their state. Fire extinguishing agents in different states have their own application occasions, among which liquid fire extinguishing agents have a better treatment effect on common Class A fires and Class B fires. Liquid fire extinguishing agents can be subdivided into water-based fire extinguishing agents, protein foam fire extinguishing agents, aqueous film-forming foam fire extinguishing agents, solvent-resistant foam fire extinguishing agents, and high-expansion foam fire extinguishing agents according to the types of foaming agents. Since commercia...
