Embodiment Construction

[0032] Below in conjunction with embodiment the present invention will be further described:

[0033] 1. The ingredients of sepiolite flame retardant foaming agent are composed of the following components by weight percentage: dried sepiolite 56%, activated attapulgite clay 8%, sodium bicarbonate 24%, sodium alkylbenzene sulfonate 10% %, sodium polyacrylate 0.6%, sodium pyrophosphate 0.5%, ammonium polyphosphate 0.5% and zinc borate 0.4%.

[0034] The production method of the sepiolite flame retardant foaming agent: input the ingredients of the sepiolite flame retardant foaming agent into the mixer for stirring, 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 sepiolite flame retardant blowing agent.

[0035] 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 i...

Abstract

The invention discloses a sepiolite flame-retardant foaming agent. The technical scheme has the following key points: the sepiolite flame-retardant foaming agent consists of dried sepiolite, activated attapulgite, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate. Ingredients of the sepiolite flame-retardant foaming agent are stirred, grinded and packaged so as to obtain a finished product of the sepiolite flame-retardant foaming agent. The sepiolite flame-retardant foaming agent is added with water, and is stirred at high speed, a great amount of gas can be released rapidly so as to form porous foam mud; the foam mud is jetted by a high-pressure water gun to be directly used for extinguishment, and is stably covered on the surface layer of a combustible material so as to form a foam mud membrane; the foam mud membrane can be used for isolate the contact of the combustible material and air rapidly, and can prevent the combustible material from combusting continuously so as to achieve the aims of flame retardance and extinguishment. The sepiolite flame-retardant foaming agent is suitable for producing flame-retardant and extinguishing, light board material, light wall bodies and sound-attenuating and noise-reducing products.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a sepiolite 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 ...
