Description
Technical field
The invention belongs to building material field, be specifically related to a kind of method that interior wall dry powder and mortar prepared by reclaimed materials.
Background technology
Along with the fast development of building industry, the requirement to building industry quality is more and more higher.Due to the skill by workmen
A various raw-material impact such as art proficiency level and cement, sand etc., the mortar of job site configuration, either masonry mortar,
Decorative mortar or floor leveling mortar, usually occur building motar cracking phenomena (even if the most traditional clay wall
Brick uses cement mortar to plaster also to there will be Large Area Cracking), thus cause that construction quality is unstable, intensity is beaten less than requiring,
The most bum situation happens occasionally, it has also become construction quality common fault.Additionally, along with growth in the living standard, people couple
The requirement of self living environment increases severely the most day by day, in the construction process in house, takes insulation, heat insulation and quiet measure,
The surface of major project adds one layer of thermal insulation layer.The material started most is styrofoam thermal insulation layer, after have heat-insulation mortar bed, it is former
Reason is all that some small bubbles of vacuum form thin film and reach insulation, heat insulation and quiet effect.But wherein polyphenyl
The high-temperature resistant result extreme difference of plate, flameproof effect is the most undesirable, once causes the fire on the ground such as Shanghai, Shenyang, and state compulsion is prohibited
Stop the use of styrofoam.And inorganic kervit microbead insulated sand slurry is owing to forming with incombustible inorganic material, comparatively speaking than
Safer, but its cost is high, can cause Engineering Overall cost increase.A kind of fragility of searching is low, tensile strength big, heat preservation energy-saving
And the mortar of low cost is always the study hotspot in building material industry.
The refractory material of field of steel-making is after being used for multiple times, and various performances are greatly reduced, it is impossible to meet the needs of steel-making,
And these refractory materials contain the compositions such as substantial amounts of corundum, cement, these compositions can be applied to dry powder and mortar.
Summary of the invention
Present invention aims to the problem that prior art exists, it is provided that interior wall dry powder sand prepared by a kind of reclaimed materials
The method of slurry.
The method of interior wall dry powder and mortar prepared by a kind of reclaimed materials, comprises the steps of
Step one: will reclaim refractory brick grinding particulate, after crossing 80 mesh sieves, adds redispersable latex powder and the double gold of stratiform
Belong to hydroxide, continue after stirring to grind, cross 325 mesh sieves, obtain fine powder；
Step 2: pour in blender by above-mentioned fine powder, adds bentonite, calcined shell powder, activated carbon, citric acid and silicon
Diatomaceous earth, mix homogeneously；
Step 3: the recovery firebrick particle after mistake 80 mesh sieve in step one is added continue stirring in blender all again
Even.
Preferably, being mainly composed of of described recovery refractory brick: corundum, pure calcium aluminate cement, clay, aluminium oxide, magnesium
Sand, zirconium dioxide.
Preferably, described layered double hydroxide is ferrous aluminum class layered hydroxide.
(layered double hydroxides, LDHs, also known as hydrotalcite stratiform material for layered double hydroxide
Material) it is the class anion type laminated compound with broad prospect of application, it is similar to that shepardite, and chemical general formula is
[M2+ (1-x)M3+ x(OH)2]x+(An-)x/n·yH2O.Wherein M2+、M3+Represent respectively and on laminate, occupy octahedra hydroxide centre bit
The bivalence put and trivalent metal ion, An-For interlayer exchangeable anions.Bivalence, trivalent metal cation portion with similar radius
Divide or all replace M2+And M3+Multiple binary, ternary even four-component hydrotalcite compound can be synthesized.LDHs is by positively charged
Main body laminate and interlayer anion be mutually assembled by non-covalent bond, have special interlayer anion interchangeability,
Aperture can cation collocation property, surface Acid and basic sites compossibility etc. on the shape-selective adsorptivity of modulation, layer so that it is have uniqueness
Function, not only has the ion exchanging function of similar ion exchange resin, the most special absorption and catalysis, and typically has relatively
High heat stability and the ability of acid and alkali-resistance, so becoming a kind of in catalysis, absorption, ion exchange, photoelectromagnetic, medicine and merit
Can have the new material of potentiality and prospect in the field such as macromolecular material, be widely used as catalyst, adsorbent, ion-exchanger,
Electrode material, medicinal slow release agent and fire proofing material etc..
The purpose adding layered double hydroxide in the present invention is to will reclaim the micropowder after refractory brick grinds
It is distributed to inside and the surface of layered double hydroxide, there is under the cooperation of redispersable latex powder more preferable caking property
Can, and when running into fire, owing to being uniformly dispersed, flame retardant effect is more preferable.
And the purpose being preferably ferrous aluminum class layered hydroxide is, be conducive to forming hercynite knot at concrete on fire
Structure rather than magnesia-alumina spinel structure.Magnesia-alumina spinel structure is poor with the caking property of concrete substrates, easily comes off, significantly
Affect the dry powder and mortar fire retardation to building.
Preferably, interior wall dry powder and mortar prepared by reclaimed materials of the present invention, by the component group of following percentage by weight
Become:
Add calcined shell powder and activated carbon and possess following functions: one be can effectively remove in air free formaldehyde,
The harmful substance such as benzene, ammonia and because of abnormal flavour produced by house pet, smoking, rubbish, purifies the air of a room；Two is that escherichia coli are had pole
Strong antibacterial and bactericidal action, additionally also has notable effect to Salmonella, yellow glucose fungus；Three is in former recovery refractory brick
Micro heavy have extraordinary absorption fixation, the harm of human body is negligible by heavy metal.
The useful of the present invention is effectively: adhere well to power with basal plane, and material is economical and practical, employs substantial amounts of time
Receive refractory brick, low cost, good flame retardation effect；Add layered double hydroxide to match with redispersable latex powder, increase
With the cohesive force of basal plane, when fire occurs, there is preferably flame retardant effect, add calcined shell powder and activated carbon, more ring
Protect, to human body non-hazardous.
