Description
Technical field
The present invention relates to thermal insulation mortar field, and in particular to a kind of heat-preserving dry-mixed mortar base-material and preparation method thereof.
Background technology
Main component is used for Al2O3、SiO2Gangue, during the thick desiliconization of flyash prepares aluminium hydroxide, can produce
A large amount of red muds, but in actual production, actual production for many years is found, and it is less than 3 for alumina silica ratio：1 even below 2：1 low product
Position aluminium ore production, if being produced again with this proportioning, aluminium recovery is low, and productivity effect is low, but China's alum clay resource is more
It is less than 3 for alumina silica ratio：1 even below 2：1 low-grade Al materials, so that it cannot develop；Simultaneously before silicone content is high
Put, high calcium causes to produce more red mud amounts than auxiliary material, while because substantial amounts of alkaline matter is added, causing production
Raw red mud is the high alkalinity red mud for being difficult to apply, and then pollutes environment.
The country having at present red mud is discharged into it is marine, but because of the Marine Pollution containing harmful substances such as alkali, harm fishery life
Production.What is had is stacked on land, takes farmland, pollutes water system, is waved with the wind after drying, and air is polluted again；Received for the pin of red mud
What is mainly taken is the method that disposal is stacked on seabed or land, but with the development of aluminum i ndustry, the red mud of production aluminum oxide discharge
Amount also increasingly increases, and stores up the brought a series of problems of disposal and goes out therewith, causes serious environmental problem；Red mud is in heap
During putting in addition to taking a large amount of soils, due also to the chemical composition in red mud, which infiltrates soil, easily causes soil alkalization, underground
Water pollution, these materials of people's taken long-term, will necessarily influence healthy.The major pollutants of red mud are alkali, fluoride, sodium
And aluminium etc., its content is higher, exceeded discharge standard as defined in China national (《Non-ferrous metals industry solid waste pollution is controlled
Standard》GB5058-85).
Now, China is to the utilization substantially vacancy of red mud, and constantly aluminium ore, which is developed, promotes the volume of cargo in storage of red mud constantly to increase
Greatly, the environmental pollution caused is increasingly severe, red mud comprehensive utilization is turned into one urgent need to solve the problem of aluminum smelting industry；And
In modern development, the growth of population promotes people also growing to the demand of building, for extremely frigid zones, to insulation base
The demand of material even more increasingly increases, the need for existing heat-preserving dry-mixed mortar base-material production can not meet people.
The content of the invention
The present invention provides a kind of heat-preserving dry-mixed mortar base-material and preparation method thereof, to solve above-mentioned red mud comprehensive utilization not
Enough, existing heat-preserving dry-mixed mortar base-material production can not meet technical problem the need for people.
To solve the above problems, the technical solution adopted by the present invention is as follows：
A kind of heat-preserving dry-mixed mortar base-material, is made up of the component of following parts by weight：
25-30 parts of red mud；
5-10 parts of lime stone；
5-10 parts of rare earth pulvis；
3-5 parts of re-dispersible glue powder；
Powdered 3-5 parts of anticracking additive.
Preferably, the powdered anticracking additive is made up of the component of following parts by weight：
Carbon conjugated triene-the 9,11,13- of epoxidation 18 5-10 parts of glyceryl esters of acid；
2-3 parts of lignocellulosic；
2-3 parts of HEMA；
1-2 parts of dibutyl tin laurate.
A kind of preparation method of heat-preserving dry-mixed mortar base-material, comprises the following steps：
(1) red mud and half rare earth pulvis are added water to form slurry, and adds fixedness acid solution and be adjusted, by slurry
It is standby that pH value adjusts to 7-8 dry milling；
(2) by limestone powder, re-dispersible glue powder and powdered anticracking additive, second half rare earth pulvis and step
(1) red mud powder made from, which is mixed, is made heat-preserving dry-mixed mortar base-material.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
(1) in the present invention, red mud is effectively utilized, while solving red mud comprehensively utilizes inadequate, existing heat insulation dry-mixing sand
Slurry base-material production can not meet two technical problems the need for people；
(2) red mud contains Al2O3, because the component in rare earth pulvis such as Y2O3, La2O3, Sm2O3 etc. are good surfaces
Active material, can improve the wettability of the red mud containing Al2O3, so in preparation process, can promote red mud fully and water
Uniform sizing material is combined to form, is easy to even regulation pH value；
(3) add water in use, CaO in Y2O3, La2O3, Sm2O3, La2O3, Fe2O3 and lime stone in rare earth pulvis
Gas can be produced after being reacted to each other etc. component, the stomata of closing is formed so that is had using the warming plate of product of the present invention uniform
Sealed porosity, uniform insulated cavity is formed, so that heat-insulating property is good；
(4) the carbon conjugated triene -9,11,13- of epoxidation 18 acid glyceryl ester is by illumination in powdered anticracking additive
Curable and viscous stickiness excellent, using this product, can be such that building was dried in 24 hours, substantially reduce drying time,
The splendid viscous stickiness of the carbon conjugated triene -9,11,13- of epoxidation 18 acid glyceryl esters plays excellent bonding effect to each component
Really, so as to prevent cracking, adapt to require high building to cracking resistance completely；Whole only to add water using process, product is without having
Evil waste is produced, extremely friendly to environment；Preparation method is simple, and production cost is low, can produce and apply extensively.
