Powdery gangue foaming agent

Abstract

The invention discloses a powdery gangue foaming agent. Main points of the technical scheme are as follows: the powdery gangue foaming agent is composed of gangue, hyperviscous attapulgite, active attapulgite, sodium dodecyl sulfate, sodium percarbonate, sodium polyacrylat, sodium acid pyrophosphate and sodium poly(naphthaleneformaldehyde) sulfonate; and the ingredients of the powdery gangue foaming agent undergo stirring, milling and packaging to obtain a finished product, namely the powdery gangue foaming agent. The powdery gangue foaming agent has advantages of strong foaming capability, high bubbling times, large quantity of foams produced per unit volume, good toughness of outer foam film capable of not being easily broken, good foam stability, no defoaming for a long time, fine foam, uniform size of pores generated inside a medium, low bleeding amount, good compatibility of the medium used and the like. Products produced by the use of the powdery gangue foaming agent can be used to effectively control noise pollution and also have functions of heat insulation and air purification. The powdery gangue foaming agent is suitable for production of lightweight sheet materials, lightweight walls and noise reduction products.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a powdery coal gangue 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 some m...

Problems solved by technology

[0007] China has accumulated more than 1 billion tons of coal gangue, and 100 million tons of coal gangue will be discharged every year. It not only accumulates and occupies land, but also pollutes the air spontaneously or causes fires, polluting the atmosphere, and coal gangue stacked in the open air will generate a lot of dust. Thi
