Abstract

The invention discloses a foam fire extinguishing agent with a high-efficiency environment-friendly evaporation-inhibiting function. The foam fire extinguishing agent is characterized by comprising the following components in percentages by weight: 1% to 6% of an evaporation inhibiting agent, 1% to 6% of a fluorocarbon surfactant, 4% to 16% of a hydrocarbon surfactant, 2% to 6% of a polymer thickening foam stabilizer, 4% to 10% of a cosolvent, 4% to 10% of a pour point depressant, 0.1% to 0.5% of a preservative, and the balance of water. According to the foam fire extinguishing agent capable of inhibiting the volatilization of fuel and having the high-efficiency environment-friendly evaporation-inhibiting function, the coverage inhibition performance of the fire extinguishing agent can beimproved, and when foam is sprayed onto an oil surface, a dense multiphase composite film is formed at the oil interface, so that the volatilization of flammable liquids and oil can be effectively prevented, and fire is prevented from having re-combustion.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing, in particular to a foam fire extinguishing agent with high-efficiency, environment-friendly and steam-suppressing functions and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economic construction and the enhancement of comprehensive strength, the petrochemical industry has made great progress. The volume of storage tanks for petroleum and chemical products is getting bigger and bigger, and there are more and more. With such a large-scale tank body and tank area capacity, and the centralized storage of most storage tanks, the probability of fire hazard will increase. If such a fire occurs, it will be difficult to fight and rescue, and it is prone to re-ignition and secondary disasters, causing serious damage. Economic losses and casualties. [0003] Oil products are also widely used, and the development of the a...
