Specific embodiment:
The invention will be further described With reference to embodiment:
A kind of mortar plasticising water-retaining agent, by mass percentage, including following components, bentonite: 30%, metakaolin:
31.5%, cellulose ether: 1.5%, diatomite: 37%.Wherein, bentonite is sodium bentonite made of being modified, and kaolin is
Metakaolin, diatomite are the diatomite of acidleach neutralisation treatment, and cellulose ether is hydroxyethylmethylcellulose.
Preparation method is as follows, and a kind of production technology of mortar plasticising water-retaining agent includes the following steps:
Inorganic salts are uniformly mixed in bentonite and are modified processing by the first step, raw material preparation, and are deposited with plastic foil covering
7 days or more (so that the sodium ion in inorganic salts enters in the layer structure of montmorillonite) is put, is expressed to through double helix mixing dry
In dry kiln, in 550-650 DEG C of kiln body while mixing while roast, be fired mixing bentonite it is cool postpone it is levigate extremely by ball mill
It is more than 500 mesh spare；Acidleach processing is carried out to diatomite with dilute sulphuric acid, separates iron aluminium impurity in diatomite, while decomposing silicon
Organic matter in diatomaceous earth inner hole increases internal surface area, improves the attraction performance of diatomite, in lime and extra acid, through stone
Ash neutralize obtain calcium sulfate again drying it is levigate to the calcium sulfate more than 500 mesh, neutralized through lime can in metakaolin
Active silica, aluminum oxide form new silicate mineral；
Modified alta-mud, metakaolin, the acid diatomite neutralized, hydroxyethylmethylcellulose are distinguished spiral shell by second step
Rotation is transported on electrical metering device and weighs in proportion, then with plough coulter type mixing machine mechanical stirring it is uniform after packed or dissipated
It is packed into library, mixing time is no less than 2min.
The effect of each material in the present invention
Bentonite has hygroscopicity and thickening effect；The water of adsorbable 8~15 times of own vols of dilatancy, bentonite,
Volume expansion is up to several times to 40 times；It can be dispersed into as a form of gel and suspension in an aqueous medium, there is suspension；This medium is molten
Liquid has certain viscosity, plasticity；There is stronger cation exchange capacity (CEC) and there is the repellency to acid ion.
Metakaolin is a kind of artificial pozzolanic material of high activity, can be with Ca (OH)2(CH) and water generation volcanic ash is anti-
It answers, generates the hydrated product similar with cement.Using this feature, when being used as grout additive, in cement hydration process
The CH of generation reacts, and can improve certain performances of mortar.Mainly AS2, CH reacted with water, with AS2The ratio and reaction of/CH
The difference of temperature can generate different hydrated products, active silica and active aluminum oxide and mortar in metakaolin
The calcium oxide being precipitated when middle hydrated cementitious generates new silicate mineral, improves compression strength, effectively inhibits the accumulation of salt in the surface soil, improves simultaneously
Impermeability.
Ethoxyl methyl cellulose ether: the effects of increasing water conservation, suspending, thicken, stablizing is affected by temperature small.
Diatomite: having the characteristics such as superfluorescent fiber, Porous, and ultra tiny boring ratio charcoal is 5000 to 6000 times out more.
When humidity rises, ultra micro pore can moisture content in automatic absorption mortar, stored.If the moisture content in mortar
It reduces, humidity decline, diatomite can release the moisture content being stored in ultra micro pore, play water retention.
Present invention volume 0.5~1.0% in premixing mortar, up to 92% or more, remaining indices reaches water retention
National standard meets the performance requirement manually or mechanically constructed, solves the problems, such as premixing mortar use, construction efficiency
3~5 times are improved, the development for pushing the sector is conducive to.
Specifically used method of the invention is as follows: the building mortar of Site, mortar of the invention can be retained thick dose
It is added before adding water and stirring, is added water and stirred 3~5 minutes together with the materials such as cement bonded sand.Mortar plasticising water-retaining agent is being built
Dosage in mortar is 0.5~1.0%.When the common dry-mixed mortar of premixing dry-mixed mortar plant produced, the present invention is transported to pre-
It mixes in dry-mixed mortar factories library, by different mortar kind mortar mix ratio setting ratios, enters mixing through electronic measurement and set
Standby to be stirred, mixing time was at 2 minutes or more, to guarantee product quality.Mortar modifier mixing in common dry-mixed mortar
Amount is 0.5~1.0%.
For proof reliability of the invention, performance indexes of the invention is detected, detection method and foundation:
" building mortar basic performance tests method " JGJ/70-2009, JG/T164-2004 " masonry mortar plasticizer ", JC/T2389-
2017 " premixing mortar water-retaining agent ", " premixing mortar " GB/T25181-2010 standard.As a result as follows:
Mortar plasticising water-retaining agent of the invention have good anti-sag, water conservation and it is easy, subtract modeling barrier performance.Therefore originally
Invention has the advantage that 1 present invention meets JG/T164-2004 " masonry mortar plasticizer " standard requirements, meets newest " pre-
Sand cutting slurry " GB/T25181-2010 standard premixing build, plastering, ground mortar performance indexes.With traditional lime,
Bleed class additive is compared, and there is adhesion strength to improve, water-fast, freezing and thawing performance is good；With it is good subtract modeling, cracking resistance, resist it is general
Alkali, antiseepage, endurance quality；With sag resistance, pumping, implementable automatic arc spraying；For sea sand, Machine-made Sand, natural sand
Well adapting to property.
In conclusion mortar of the invention is plasticized water-retaining agent, it is a kind of additive for premixing dry-mixed mortar, makes mortar
With it is good and easy, subtract modeling, antiseepage, the anti-accumulation of salt in the surface soil, anti-freezing property, improve the durability of building；Good sag resistance, pump
