Description
Technical field：
The present invention relates to a kind of construction material, more particularly to a kind of steam-pressing aero-concrete for adding dodecyl sodium sulfate
Building block.
Background technology：
Autoclave aerated concrete building block is a kind of low energy consumption, the New Building Materials of environment-friendly type, has light-weight, heat preservation
The advantages that heat-proof quality is good, intensity is high, anti-seismic performance is good, processing performance is good, high temperature resistant, good sound insulation value.It is with siliceous material
Material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement) are primary raw material, and admixture foaming agent (aluminium powder) is logical
Cross light porous silicate product made of the technical process such as dispensing, stirring, cast, precuring, cutting, steam pressure, maintenance.Steam pressure adds
Gas concrete production abundant raw material is raw material especially with flyash, and it is dirty can to comprehensively utilize industrial residue, Environment control
Dye does not destroy arable land, and can create good Social benefit and economic benefit, is that a kind of replacement traditional solid clay brick is preferable
Materials for wall is subject to national wall to change the support energetically of policy, the tax policy and environmental protection policy, has a vast market hair for many years
Exhibition prospect.
With the progressively implementation of national energy-saving emission reduction policy, steam-pressing aero-concrete increasingly attracts attention.The prior art
In have powder ash air-entrained concrete building block, a kind of addition magnesia, the flyash of magnesium chloride add as disclosed in CN104211436B
Gas concrete segment includes the component of following parts by weight：65~70 parts of flyash, 15~20 parts of quick lime, 5~10 parts of cement,
2.83~3.83 parts of ardealite, 0.1 part of aluminium powder, 0.05 part of foam stabilizer, magnesia and magnesium chloride mix 0.02~0.04 part；The block
Block, as raw material main constituents, is not only reduced production cost, and makes the air-entrained concrete building block using three-level flyash
Intensity increase, compressive property enhancing；The air-entrained concrete building block adds a certain amount of magnesia, magnesium chloride solution, can improve
The rate of set of building block, enhancing building block bear pressure, shorten the time of steam pressure in production technology, saved production cost, made life
Production efficiency greatly improves, and improves product flame retardant effect and product function.In consideration of it, further to promote the performance of product and product
Matter especially promotes the intensity of building block, is played and got angry, surely in autoclave aerated concrete building block preparation process by additive
Many-sided effect such as bubble, diminishing, adjustment aperture and distribution, as the core material of steam-pressing aero-concrete, develops one
The autoclave aerated concrete building block of kind addition dodecyl sodium sulfate.
The content of the invention：
The steam pressure that the purpose of the present invention is intended to provide the addition dodecyl sodium sulfate that a kind of intensity is high, compressive property is good adds
Gas concrete segment.
In order to achieve the above objectives, the present invention takes following technical scheme：
The autoclave aerated concrete building block of dodecyl sodium sulfate is added, includes the component of following parts by weight：Flyash 60
~75 parts, 15~25 parts of quick lime, 5~10 parts of cement, 2.5~4.5 parts of ardealite, 0.05~0.15 part of aluminium powder, magnesia and
0.02~0.05 part of the mixture of magnesium chloride, 0.005~0.01 part of dodecyl sodium sulfate, hydroxypropyl methyl cellulose 0.005
~0.01 part.
Flyash uses the three-level flyash that fineness reaches standard requirement for 25~30, compared with the level-one generally used
Flyash, second class powered coal ash are at low cost, can refuse reclamation, production cost can be substantially reduced, hence it is evident that increase air entrained concrete
Intensity, compressive property is good.
Aluminium powder uses aluminium powder cream, easy to use, and the Minute pores to be formed is made to have good gas in building block preparation process
Pore structure.In production air-entrained concrete building block processing grinding processes, in order to avoid Fire explosion, it is also necessary to add in a certain amount of
Dry aluminium powder degreasing agent, addition are generally the 1%~4% of aluminium powder.
It by volume ratio is 1 that the mixture of magnesia and magnesium chloride, which is,:1 magnesium oxide solution mixed with magnesium chloride solution and
Into.A certain amount of magnesia and magnesium chloride solution are added in the autoclave aerated concrete building block of the present invention can improve the solidifying of building block
Speed is tied, enhancing building block bears pressure, shortens the time of steam pressure in production technology, so as to save production cost, make production efficiency
It greatly improves.
Dodecyl sodium sulfate (SDS) is a kind of anion surfactant, has excellent infiltration, washing, soaks, goes
Dirty and emulsification is used as emulsifier, flotation agent and penetrant in chemical industry and light and textile industries.Hydroxypropyl methyl cellulose (HPMC)
It is the nonionic cellulose compound ether made of cotton, wood are through processes such as alkalization, propylene oxide and chloromethanes etherificates.Hydroxypropyl first
Base cellulose (HPMC) dispersion performance in cold water is good, viscosity is high, thickening good water-retaining property, is suitble to the production of glue for building,
It can be used for building a wall, plaster, paint, in the constructions such as filleting, while can be also suitably used for dry-mixed solidifying mortar.The present invention's is steam pressurized
While a certain amount of dodecyl sodium sulfate (SDS) is added in concrete segment, equal proportion adds in a certain amount of hydroxypropyl first
After base cellulose is mixed, because that aluminium powder can be assisted to be formed is composite foamed for dodecyl sodium sulfate (SDS), got angry in slurry
Gas and " liquid " form binary system in journey, and gas is made to be dispersed in a Continuous Liquid Phase, is passed through when there is air containing 12
In sodium alkyl sulfonate and the slurry of hydroxypropyl methyl cellulose, blibbing is just provided with double wall film, and bubble can be made steady for a long time
Surely exist, intensity is promoted so as to achieve the effect that reduce density.
The autoclave aerated concrete building block of present invention addition dodecyl sodium sulfate uses three-level flyash to make except having
For attainable performance and technology are imitated after raw material main constituents and a certain amount of magnesia of addition and magnesium chloride mixture
Beyond fruit, it is with the addition of a certain amount of aluminium powder and dry aluminium powder degreasing agent and ensures the quality of product simultaneously, the dodecyl sodium sulfonate of addition
Sodium and hydroxypropyl methyl cellulose further improve the intensity of product, compressive property enhancing.Therefore, present invention addition 12
The autoclave aerated concrete building block of sodium alkyl sulfonate not only has high intensity, high pressure resistance energy, and production cost is low, production effect
Rate is substantially improved, and there is certain extensive use to be worth.
