Problems solved by technology

The N-1 type (liquid hydrocarbon) inhibitor successfully developed in my country in 2001 is a combination of semi-condensed film and liquid monomolecular film, which can inhibit the partial evaporation of combustible liquid hydrocarbons, but due to its density Relatively large, only water-soluble but not oil-soluble, so it is limited in use

Abstract

The present invention relates to liquid hydrocarbon evaporation inhibitor and its preparation process. The liquid hydrocarbon evaporation inhibitor consists of hydrocarbon surfactant 2.5-30 wt%, fluoric surfactant 10-30 wt%, spreading agent 1-8 wt%, filming agent 1-10 wt%, stabilizer 0.1-10 wt%, antifreezing agent 1-30 wt% and water for the rest. The present invention can inhibit the evaporation of liquid hydrocarbon effectively to avoid fire accident.

Description

technical field [0001] The invention relates to an inhibitor for preventing volatilization of liquid hydrocarbons and a preparation method thereof, in particular to a liquid hydrocarbon evaporation inhibitor and a preparation method thereof. Background technique [0002] With the development and progress of human society, the use and demand for liquid hydrocarbons continue to increase, but liquid hydrocarbons will inevitably evaporate in large quantities during production, transportation, storage and use, which not only wastes a lot of resources, but also pollutes the environment. What's more serious is that some liquid hydrocarbons (especially fuel oils) will burn and cause a fire when they encounter static electricity or a fire source due to their natural large-scale evaporation, which seriously threatens people's lives and property. In order to suppress the evaporation of liquid hydrocarbons, many developed countries in the world and relevant units in my country are devel...
