Abstract
The invention discloses a volcanic ash flame-retardant foaming agent. The point of the technical scheme is as follows: the volcanic ash flame-retardant foaming agent consists of volcanic ash, high-viscosity attapulgite clay powder, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate, wherein the ingredients of the volcanic ash flame-retardant foaming agent are stirred, ground and packaged to obtain a finished product of the volcanic ash flame-retardant foaming agent. After the volcanic ash flame-retardant foaming agent is added with water and stirred at a high speed, a great quantity of gas is quickly released to form porous foam slurry; the foam slurry is sprayed by a high-pressure water gun and is directly used for putting out a fire; the foam slurry stably covers the surface layer of a combustible material to form a foam slurry film; the foam slurry film can quickly isolate contact between the combustible material and the air so as to prevent the combustible material from continuously burning to achieve the aims of flame retardance and fire extinguishment; and the volcanic ash flame-retardant foaming agent is suitable for producing flame-retardant fire-extinguishing light plates, light walls and silencing noise reduction products.
Description
Technical field
