Abstract
The invention discloses a mica flame retardant foaming agent which is composed of sericite, hyper-viscous attapulgite clay powder, activated attapulgite clay, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate. The ingredients of the mica flame retardant foaming agent are stirred, ground and packaged to obtain a finished product of the mica flame retardant foaming agent. After water is added to the mica flame retardant foaming agent to be stirred at a high speed, a large amount of gas is quickly released, and then porous foam slurry is formed; the foam slurry is sprayed by a high-pressure water gun and directly used for extinguishing fires; and the foam slurry is stably covered on the surface layers of flammable materials to form a foam slurry film which can quickly isolate the flammable materials from air to prevent the flammable materials from continuously burning, so that the purposes of flame retardant and fire extinguishing are achieved. The mica flame retardant foaming agent is suitable for producing flame retardant and fire extinguishing products, light plates, light walls and sound attenuation and noise reduction products.
Description
Technical field
The present invention relates to whipping agent, be specifically related to flame-retardant expanded dose of a kind of mica.
Background technology
City noise is having a strong impact on city resident's orthobiosis and health of human body, city noise mainly refers to traffic noise, factory noise, construction noise pollution and noise of social activities, its The noise scope and influence degree are serious day by day, to the influence of civic living environment greatly, become one of noticeable city environmental pollution problem.
The control noise is taked measures such as damping, sound insulation, sound absorption, sourdine, personal protection and architectural composition usually, weaken as far as possible or reduce the vibration of sound source, acoustic energy absorption in propagating is fallen, place obstacles and make that sound is all or part of to reflect away, weaken the effect of noise, to reach the purpose of control noise.
Usually adopt quieter material to produce products such as some acoustical panels, sound insulation Wall, sound-absorbing net and sound damper and control sound pollution, it is after handling by foaming, to improve the performance of the said products that some materials are also arranged.
The kind of whipping agent is more, and for the control sound pollution has been made bigger contribution, but the said products can only be used for the control sound pollution, does not have fire-retardant effect and the function that purifies air.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, flame-retardant expanded dose of a kind of mica is provided.
Mica glues attapulgite clay powder, activated attapulgite, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, trisodium phosphate, ammonium polyphosphate and zinc borate by sericite, height for flame-retardant expanded dose and forms.
The production method that mica is flame-retardant expanded dose: will stir in flame-retardant expanded dose of batching input of the mica stirrer, carry out abrasive dust in the back input grinding machine that stirs, be packaged as the finished product of flame-retardant expanded dose of mica.
Mica has characteristics such as good elasticity, toughness, insulativity, high temperature resistant, acid and alkali-resistance, corrosion-resistant, strong adhesion and satin luster, sericite has high resistance, be excellent insulating material and fire-retardant filler, sericite can significantly change a series of physics modulus of material, form or change the visco-elasticity of material, this class material absorbs vibrational energy expeditiously, weakens shock wave and sound wave, is used to prepare noise elimination, sound insulation, damping coating, and the present invention selects sericite for use.
Attapulgite has another name called polygorskite or Palygorskite, be a kind of layer of chain-like structure contain Shuifu County's zeopan clay mineral, attapulgite has unique layer chain-like structure feature, in its structure, there is the lattice displacement, so contain Na+, Ca2+, Fe3+, the Al3+ of non-quantitative in the crystal, crystal is needle-like, fibrous or fiber collection shape.Attapulgite has unique dispersion, high temperature resistant, anti-good colloidal property such as saline and alkaline and higher adsorptive power, and has certain plasticity-and cohesive force.
