Water-based multiphase fire-fighting agent for extinguishing burning diesel oil and preparation method thereof

Abstract

The invention discloses a water-based multiphase fire-fighting agent for extinguishing burning diesel oil and a preparation method thereof. , 0.03-0.08 parts of preservatives, and the remainder is water, a total of 100 parts (weight), the raw material powder is a solid powder particle, the raw material powder consists of bicarbonate sealed and wrapped, polyphosphate sealed wrapped, Composed of non-metallic mineral particles. The hermetically wrapped bicarbonate of the present invention and the hermetically wrapped polyphosphate are decomposed by heat and release molecules such as carbon dioxide and ammonia after being exposed to fire. For example, the molecular structure of mica and graphite is stable, and it has the characteristics of high temperature resistance, strong acid and alkali resistance, and can realize the isolation effect on the combustion flame.

Description

technical field

[0001] The invention relates to the field of fire protection, in particular to a water-based multiphase fire extinguishing agent for extinguishing burning diesel and a preparation method thereof. Background technique

[0002] Gases, solids, and liquids are different phases that can transform into each other under certain conditions. Homogeneous multiphase systems are widely used in industry. In the heterogeneous system described in the patent with publication number CN1349505C, a method for preparing tribromomethanesulfonylpyridine by reacting methylthiopyridine with hypobromite. The publication number is CN109134187B, which describes a new process and preparation method for the synthesis of highly sterically hindered bromobenzene, including aniline hydrobromide and inorganic nitrite, in the presence of water and one or more inert solvents Next, in the two-phase or multi-phase system formed. The process does not require heavy metal salt catalysis, does not...
