Abstract

The invention discloses a phosphogypsum flame retardant foaming agent. The technical scheme is characterized in that the phosphogypsum flame retardant foaming agent is composed of phosphogypsum, high-viscosity attapulgite clay powder, active attapulgite clay, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate which are dehydrated; and all the ingredients of the phosphogypsum flame retardant foaming agent are stirred, ground and packaged to obtain a finished product of the phosphogypsum flame retardant foaming agent. After water is added into the phosphogypsum flame retardant foaming agent and the mixture is stirred at a high speed, a great amount of gases are rapidly released, and thus, porous foam sludge is formed; the foam slurry is directly used for extinguishing a fire after being sprayed by using a high-pressure water gun; the foam slurry is stably covered on the surface layer of a combustible material to form a foam slurry film which can be used for rapidly isolating the contact of the combustible material and the air and preventing the combustible material from continuing combusting, and thus, the aims of flame retarding and fire extinguishing are achieved; and the phosphogypsum flame retardant foaming agent is suitable for producing flame retarding and fire extinguishing products, light boards, light walls and silencing and noise reducing products.

Description

technical field

[0001] The invention relates to a foaming agent, in particular to a phosphogypsum 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, ...

Embodiment Construction

[0036] Below in conjunction with embodiment the present invention will be further described:

[0037]1. Phosphogypsum flame retardant foaming agent ingredients are composed of the following components by weight percentage: dehydrated phosphogypsum 26%, high-viscosity attapulgite clay powder 14%, active attapulgite clay 16%, sodium bicarbonate 28% , Sodium Alkylbenzene Sulfonate 13.8%, Sodium Polyacrylate 0.8%, Sodium Pyrophosphate 0.6%, Ammonium Polyphosphate 0.4% and Zinc Borate 0.4%.

[0038] The production method of the phosphogypsum flame-retardant foaming agent: input the ingredients of the phosphogypsum 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 it is packaged as phosphogypsum Finished product of flame retardant blowing agent.

[0039] The dehydrated phosphogypsum production method: input the water-containing phosphogypsum into an airflow dryer for deh...
