Abstract

The invention provides an extinguishant and a preparation method and application thereof. The extinguishant comprises, by weight, 35-55% of potassium carbonate, 0.5-5% of APG and 40-60% of water. The preparation method includes the steps: a), adding the potassium carbonate into water, and stirring to enable the potassium carbonate to be dissolved so as to obtain a potassium carbonate solution; b), adding the APG into the potassium carbonate solution, and stirring prior to cooling and settling to obtain the extinguishant. The application of the extinguishant is used for extinguishing fire caused by vegetable oil. The extinguishant is simple to prepare, low in production cost, good in extinguishing effect and safe and non-toxic.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to a fire extinguishing agent and its preparation method and application. Background technique [0002] Fire is one of the most frequent and most common major disasters that endanger public safety and social development. Specifically, fire refers to disasters caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of civilization progress. Therefore, the history of human use of fire and the history of fighting against fire go hand in hand. While using fire, people constantly summarize the law of fire occurrence and minimize fire and its harm to human beings. [0003] According to the type and combustion characteristics of combustibles, fires are divided into six categories: A, B, C, D, ...
