Abstract

The invention relates to a foam extinguishing agent containing a biosurfactant and a preparation method for the foam extinguishing agent. The problems that an existing foam extinguishing agent is liable to pollute the environment and the preservation time is short are mainly solved. The foam extinguishing agent containing the biosurfactant comprises, by weight, 10%-30% of rhamnolipid, 3%-15% of sophorolipid, 0.1%-0.5% of a thickening agent, and the balance water. The preparation method for the foam extinguishing agent comprises the steps that under the stirring condition, the rhamnolipid is added into a certain amount of water, and after even stirring, the sophorolipid is added; after even mixing, the mixture is heated to 80 DEG C-90 DEG C in a reaction kettle; after the mixture is cooled to the room temperature, sodium alginate is dissolved with 10% of water and added to the reaction kettle; and the balance water is added as a complement, and the mixture is mixed evenly. According to the foam extinguishing agent containing the biosurfactant, the fire extinguishing performance of the extinguishing agent can be improved, fast biodegradation of pollutant in a place where a fire disaster occurs is achieved, and thus the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of biosurfactant application, and in particular relates to a formula and a preparation method of a foam fire extinguishing agent containing biosurfactant. Background technique [0002] Even in countries with a small population, tens of thousands of fires occur every year. The occurrence of fire is a serious problem facing human society. It 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. As a conventional fire extinguishing agent, water-based fire extinguishing agent has been approved and used. Water-based foam fire extinguishing agent is a physical fire extinguishing agent. After spraying the burning material, a fine water mist is formed, which quickly spreads on the fire scene and real...
