Embodiment Construction

[0034] Below in conjunction with embodiment the present invention will be further described:

[0035] 1. Fly ash flame retardant foaming agent ingredients are composed of the following components by weight percentage: dried fly ash 50%, high-viscosity attapulgite clay powder 8%, sodium bicarbonate 28%, alkylbenzenesulfonic acid Sodium 12%, sodium polyacrylate 0.8%, sodium pyrophosphate 0.5%, ammonium polyphosphate 0.4%, and zinc borate 0.3%.

[0036] The production method of the fly ash flame retardant foaming agent: input the ingredients of the fly ash flame retardant foaming agent into the mixer for stirring, and after stirring evenly, input it into the mill for grinding, the particle fineness is ≤0.044 mm, and the package is The finished product of fly ash flame retardant blowing agent.

[0037] The production method of the dried fly ash is as follows: transport the fly ash to a rotary drying furnace for drying, the drying time is 2 hours, the drying temperature is control...

Abstract

The invention discloses a pulverized fuel ash flame retardant foaming agent. The technical scheme has the following key points: the pulverized fuel ash flame retardant foaming agent comprises dried pulverized fuel ash, high-viscosity attapulgite clay powder, sodium hydrogen carbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate. The finished product of the pulverized fuel ash flame retardant foaming agent is prepared by stirring, grinding and packaging the ingredients. Water is added into the pulverized fuel ash flame retardant foaming agent, and a great deal of gas is rapidly released after the water solution is stirred at high speed, so that porous foam slurry can be formed; the foam slurry is jetted by a high-pressure water gun so as to be directly used for putting out a fire; the foam slurry is stably covered on the surface layer of a combustible material so as to form a foam slurry film; and the foam slurry film can rapidly isolate the contact between the combustible material and the air, and the combustible material is prevented from continuously burning, so that the aims of inflaming retarding and extinguishing a fire can be achieved. The pulverized fuel ash flame retardant foaming agent is suitable for producing light weight boards, light weight walls and noise reduction products which have inflaming retarding and fire extinguishing functions.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a fly ash flame retardant foaming agent. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0003] To control noise, measures such as damping, sound insulation, sound absorption, muffler, personal protection, and building layout are usually taken to minimize or reduce the vibration of the sound source, absorb the sound energy in propagation, and set up obstacles to reflect all or part of the sound. Reduce the effect of noise to achieve the purpose of controlling noise. [0004] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and silencers to control noise pollution, and so...
