Abstract
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...
