Foam extinguishing agent special for kitchen and preparation method of foam extinguishing agent

Abstract

The invention discloses a foam extinguishing agent special for a kitchen and a preparation method of the foam extinguishing agent. The foam extinguishing agent is prepared from, by weight, 40%-60% of a foaming agent, 10%-20% of a surfactant, 5%-10% of biological polysaccharide, 0.5%-2% of wollastonite powder, 4%-6% of a foam stabilizer, 4%-6% of a cosolvent and the balance water. The foam extinguishing agent comprises the following steps: S1, adding tap water into a reaction kettle, adding a cosolvent into the reaction kettle, heating to 60-75 DEG C, and stirring at a high speed to obtain a mixed solution; S2, adding a foaming agent, a foam stabilizer, biological polysaccharide, a surfactant and wollastonite powder into the mixed solution obtained in the step S1, and stirring at a high speed to obtain a mixed solution; S3, adjusting the pH value of the mixed solution obtained in the step S2 to 7.2-8.5 to obtain the mixed solution; and S4, performing natural standing on the mixed solution obtained in the step S3, and carrying out defoaming treatment to obtain the foam extinguishing agent special for the kitchen. According to the foam fire extinguishing agent special for the kitchen and the preparation method of the foam fire extinguishing agent, burning edible oil can be rapidly extinguished, and the risk that the edible oil splashes during fire extinguishing is reduced.

Description
