Embodiment Construction
[0030] Below in conjunction with embodiment the present invention will be further described:
[0031] 1. The powdered sepiolite foaming agent ingredients are composed of the following components by weight percentage: dried sepiolite 52%, active attapulgite clay 8%, sodium lauryl sulfate 26%, sodium percarbonate 12.4% %, 0.6% sodium polyacrylate, 0.5% sodium pyrophosphate and 0.5% sodium polynaphthaldehyde sulfonate.
[0032] The production method of the powdery sepiolite foaming agent: input the ingredients of the powdery sepiolite 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 packaging is The finished product of powdered sepiolite blowing agent.
[0033] The production method of the dried sepiolite is as follows: ① put the raw ore of the sepiolite into the pulverizer for pulverization, and the particle fineness after pulverization is ≤2 mm; ② transport the pulverized sepi...

Abstract
The invention discloses a powder sepiolite foaming agent. The key point of the technical scheme is as follows: the powder sepiolite foaming agent consists of dried sepiolite, high-viscosity attapulgite clay powder, lauryl sodium sulfate, sodium percarbonate, sodium polyacrylate, sodium pyrophosphate and sodium polynaphthylene sulfonate. Ingredients of the powder sepiolite forming agent are stirred, milled and packaged to obtain a finished product of the powder sepiolite foaming agent. The powder sepiolite foaming agent has the advantages of being strong in foaming capacity, high in foaming multiple, large in unit volume foam yield, good in foam stability, capable of not de-foaming for a long time, fine and smooth in foams, uniform in size of holes generated in a medium, low in bleeding amount, good in compatibility with the used medium and the like, and outer films of foams are good in tenacity and unlikely to break. A product, which is produced by the powder sepiolite foaming agent, is not only capable of effectively controlling noise pollution, but also capable of achieving a thermal-insulation function and an air-purifying function. Besides, the powder sepiolite foaming agent is suitable for producing light boards, light walls and noise-reducing and de-noising products.
Description
technical field [0001] The invention relates to a foaming agent, in particular to a powdered sepiolite 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 ma...
