Abstract
The invention discloses a flame-retardant foaming agent of attapulgite. The main points of the technical scheme are that the flame-retardant foaming agent of attapulgite is prepared from active attapulgite clay, high-viscosity attapulgite clay powder, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate. Ingredients are agitated, milled and packaged into the product of the flame-retardant foaming agent of attapulgite; a lot of gases are rapidly released after water is added to the flame-retardant foaming agent of attapulgite to agitate at a high speed, so as to form porous foam mud; the foam mud is jet through a high-pressure water gun and directly used for putting out a fire; the foam mud is stably covered at the surface of a combustible material to form a foam mud film; and the foam mud film can rapidly prevent the combustible material from contacting air, and prevents the combustible material from continuing to burn, so as to achieve the targets of retarding inflaming and putting out the fire. The flame-retardant foaming agent of the attapulgite is suitable for producing flame-retardant quenching, light-board, light-wall and noise-reducing products.
Description
Technical field
The present invention relates to whipping agent, be specifically related to flame-retardant expanded dose of a kind of Attapulgite.
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 Attapulgite is provided.
Attapulgite glues attapulgite clay powder, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, trisodium phosphate, ammonium polyphosphate and zinc borate by activated attapulgite, height for flame-retardant expanded dose and forms.
The production method that Attapulgite is flame-retardant expanded dose: will stir in flame-retardant expanded dose of batching input of the Attapulgite 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 Attapulgite.
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.
Because the inner porous of attapulgite road, specific surface is big, can reach 500m
2/ g is above all can directly to be adsorbed in the duct with, positively charged ion, water molecules and a certain size the organic molecule of most (branchs), and stable electrochemical property is difficultly flocculated by ionogen, has good stability in high temperature and salt solution.Attapulgite clay selects the order of adsorptive power size to be: water〉alcohol〉acid〉aldehyde〉positive alkene〉neutral fat〉aromatic hydrocarbon〉naphthenic hydrocarbon〉alkane, straight chain hydrocarbon〉naphthenic hydrocarbon〉alkane, straight chain hydrocarbon adsorbs soon than branched-chain hydrocarbon, and bigger industrial value is also arranged in other sepn process.
The sticking attapulgite clay of described height is the attapulgite clay that adopts the complete processing production that improves viscosity of attapulgite clay, attapulgite clay soil property exquisiteness, oily soapy is arranged, light weight, property are crisp, fracture is conchoidal or irregular shape, and water-absorbent is strong, tool viscosity and plasticity-when wet, its viscosity can reach more than the 3000mPas, is conducive to the bonding between the raw material.
High sticking attapulgite clay powder refers to get 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add 372g water again, the suspension cup is placed on the homogenizer, under 11000 rev/mins rotating speed, stirred 20 minutes, to pour in the beaker of 250ml the viscosity of using NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value 〉=2200 again through the high-speed stirring sample suspension into
MPasThe attapulgite clay powder, the height that the present invention selects for use glues attapulgite clay powder particles fineness≤0.074 millimeter.
The pH value of attapulgite clay raw ore is 8～9, need to carry out acidification in the present invention, attapulgite clay after the acidified processing is activated attapulgite, the various performances of activated attapulgite all will be greatly improved, particularly strengthened the adsorption cleaning ability of Attapulgite, activated attapulgite pH value is controlled to be 5.5～7.5, water content≤2%.
Sodium bicarbonate white powder or oblique crystal crystalline powder, odorless, the flavor salty and soluble in water, its aqueous solution begins to split the carbon dioxide off and yellow soda ash in the time of 20 ℃.
Sodium alkyl benzene sulfonate white or pale yellow powder, water-soluble, easily oxidation, foaming power is strong, the detersive power height, easily with various additive compounds, cost is lower, the synthesis technique maturation, Application Areas is extensive, is very outstanding anion surfactant.
Sodium polyacrylate is a kind of new functional macromolecule material, be white or buff powder, be dissolved in cold water, stable to temperature variation, be a kind of tensio-active agent with multiple property, be conducive to improve the thickening, foaming of flame-retardant expanded dose of Attapulgite, stable, emulsification, dispersion, bonding, film forming and effect of water keeping in the present invention.
Trisodium phosphate is a kind of water white transparency crystallization or white crystalline powder, and is soluble in water, in the present invention as dispersion agent and emulsifying agent.
Ammonium polyphosphate is white crystals or amorphous fine powder, and is nonpoisonous and tasteless, do not produce etchant gas, thermostability and chemical stability height, relative density is little, and good dispersity has non-volatility in the application process, do not produce corrosive gases, advantages such as effect is lasting, and safety performance is good are a kind of non-halogen fire retardants of excellent property, ammonium polyphosphate also has the expandable flame retardant function, more is conducive to eliminate smoke, fall cigarette and anti-drippage.
