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
The present invention relates to whipping agent, be specifically related to a kind of powdery sepiolite whipping agent.
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, the range of influence of its noise and influence degree are day by day serious, on the impact of civic living environment greatly, become one of noticeable city environmental pollution problem.
Control noise and conventionally take the measures such as damping, sound insulation, sound absorption, sourdine, personal protection and architectural composition, 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 be reflected away, weaken the effect of noise, to reach the object of controlling noise.
Conventionally adopt quieter material to produce the products such as some acoustical panels, sound insulation Wall, sound-absorbing net and sound damper and control sound pollution, also having some materials is after processing by foaming, to improve the performance of the said products.
The kind of whipping agent is more, made larger contribution, but the said products can only be for controlling sound pollution, the function not purifying air for controlling sound pollution.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of powdery sepiolite whipping agent is provided.
Powdery sepiolite whipping agent is comprised of dried sepiolite, activated attapulgite, sodium lauryl sulphate, SPC-D, sodium polyacrylate, trisodium phosphate and poly-naphthaldehyde sulfonate sodium.

Sepiolite be a kind of tool layer chain-like structure containing Shuifu County's magnesium silicate clay mineral, there is sliding sense and puckery sense, sticky tongue, under drying regime, property is crisp, light weight, and shrinking percentage is low, plasticity-is good, specific surface is large, and adsorptivity is strong, and sepiolite also has decolouring, heat insulation, insulation, anticorrosive, radioprotective and the performance such as thermally-stabilised.
Sepiolite raw ore abrasive dust after drying treatment, is conducive to improve the particle fineness of sepiolite, can increase specific surface area and the adsorptive power of sepiolite.
Attapulgite has another name called polygorskite or Palygorskite, be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, attapulgite has unique layer chain-like structure feature, in its structure, has crystal lattice, therefore contain the Na of non-quantitative in crystal
+, Ca
2+, Fe
3+, Al
3+, crystal is needle-like, fibrous or fiber collection shape.Attapulgite has unique dispersion, high temperature resistant, the anti-good colloidal property such as saline and alkaline and higher adsorptive power, and has certain plasticity-and cohesive force.
The pH value of attapulgite clay raw ore is 8～9, need in the present invention to carry out acidification, attapulgite clay after acidified processing is activated attapulgite, the various performances of activated attapulgite all will be greatly improved, particularly strengthened the adsorption cleaning ability of Attapulgite, it is 5.5～7.5 that activated attapulgite pH value is controlled, water content≤2%.
Sodium lauryl sulphate is white or faint yellow powdery, water-soluble, insensitive to alkali and hard water, has decontamination, emulsification and excellent foaming power, is a kind of nontoxic anion surfactant; When powdery sepiolite whipping agent and water mix, a large amount of bubble of the common generation of sodium lauryl sulphate and SPC-D.
SPC-D is a kind of inorganic salt, and the granulated powders that is white in color can be decomposed rapidly after SPC-D contacts with water, discharges a large amount of oxygen.
Sodium polyacrylate is a kind of new functional macromolecule material, for 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 in the present invention improve the effect of the thickening, foaming of powdery sepiolite whipping agent, stable, emulsification, dispersion, bonding, film forming and water conservation.
Trisodium phosphate is a kind of water white transparency crystallization or white crystalline powder, soluble in water, in the present invention as dispersion agent and emulsifying agent.
Poly-naphthaldehyde sulfonate sodium is brown or dark-brown powder, and soluble in water, acidproof, alkaline-resisting, resistance to hard water, has good diffustivity; When powdery sepiolite whipping agent and water mix, generate a large amount of bubbles, it is more even that trisodium phosphate and poly-naphthaldehyde sulfonate sodium are conducive to the bubble distribution of generation.
The present invention is achieved by following technical proposals:
1, powdery sepiolite whipping agent batching is comprised of following component by weight percentage: dried sepiolite 25～75%, activated attapulgite 5～15%, sodium lauryl sulphate 1～35%, SPC-D 1～25%, sodium polyacrylate 0.01～5%, trisodium phosphate 0.01～5% and poly-naphthaldehyde sulfonate sodium 0.01～5%.
The production method of described powdery sepiolite whipping agent: by stirring in powdery sepiolite whipping agent batching input stirrer, input in grinding machine and carry out abrasive dust after stirring, particle fineness≤0.074 millimeter, is packaged as the finished product of powdery sepiolite whipping agent.
