Problems solved by technology

Aqueous film-forming foam fire extinguishing agents were successfully developed in the 1980s and are currently widely used. However, this type of fire extinguishing agent is limited by low temperature use, and has poor permeability in extinguishing Class A fires, and the anti-resurgence time is short.

Abstract

The invention relates to the technical field of fire retardant preparation, in particular to an environment-friendly cold-resistant water-based fire extinguishing agent and a preparation method thereof. The water-based fire extinguishing agent produced by the invention can be directly used under the low-temperature environment condition of 0-40 DEG C, and due to the addition of an anionic surfactant, the water-based fire extinguishing agent can effectively cover the surface of a combustible, block air and effectively extinguish fire from the combustion condition; and an added emulsifier has the effects of emulsification and burning resistance, and the fire extinguishing agent does not contain substances which damage or destroy the environment, can be automatically degraded after fire extinguishing, does not generate secondary pollution, and is easy to clean.

Description

[0001] The present application is the application No. 2018, November 26, 2018, and the application No. 201811414873.1, the present invention is "a" one environmentally friendly cold-resistant water system fire extinguishing agent and its preparation method ". Technical field [0002] The present invention relates to the field of fire preparation, and Background technique [0003] The combustion conditions can be effectively destroyed, and the substance of the combustion termination is referred to as a fire extinguishing agent. The fire extinguishing mechanism of the fire extinguishing agent is mainly cooling, suffocation, isolation and chemical inhibition. At present, there are several products produced by my country's fire extinguishing agent manufacturers. Several ABC dry powder, BC dry powder, water-forming film foam fire extinguishing agent and water extinguishing agent have several kinds of fire extinguishing priority, but it is not possible to destroy several and special fir...
