Description
Technical field
The present invention relates to building material technical field, and in particular to a kind of preparation method of mineral fibres thermal insulation mortar.
Background technology
Portland cement concrete is a kind of heterogeneous, more defect, the fragile material of low, the difficult flow of tensile strength, is easily existed
The effect of the load such as stretching, bending, impact, fatigue is lower to be destroyed.Portland cement concrete is applied to top course, is easily occurred too early
The diseases such as disconnected plate and surface texture destruction, thus limit its application in high-grade highway.Using fiber to coagulating cement
Soil carries out activeness and quietness, is one of important measures improved to conventional cement concrete road surface.
Numerous studies in recent years show that brucite fiber is a kind of harmless natural fiber.Brucite fiber
There is good compatibility and bond strength with excellent mechanical property, alkali resistance, water dispersible energy, and with cement.
Natural brucite fiber is adhered to one another between fiber generally in fiber assembly form output, is not easy to split point.Water-reducing agent
It is one of most important additive in cement concrete, has dissolution to mineral fibres, thus it is possible to vary the draw ratio of fiber, makes
Fiber better disperses dissociation, plays more effectively humidification in the composite.
The content of the invention
The present invention provides a kind of preparation method of mineral fibres thermal insulation mortar.
The present invention is achieved by the following technical solutions：
A kind of preparation method of mineral fibres thermal insulation mortar, carries out chemistry/heating power complex excitation to gangue, slag micropowder first
Processing, afterwards with loosen after natural brucite fiber mixed grinding after, addition lightweight aggregate, cement mixing obtain thermal insulation mortar material
Material.
The gangue, slag micropowder are exciting before processing, the square hole screen of 0.14mm are first crossed after ball mill crushing, in 100-
It is dry at 105 DEG C.
Comprise the following steps that：
（1）Activity excitation processing：
26-32 parts of slag micropowders, 14-23 parts of gangues, 2-4 parts of CaO and 4-8 parts of desulfurated plasters are added to planetary ball mill
It is interior, add wet-milling 5-15 minute under suitable quantity of water room temperature, pulpous state mixture be placed in 100 DEG C of drying in oven 6-9 it is small when, then will mix
Material high temperature sintering is closed, is cooled to room temperature, taking-up obtains active material；
（2）Brucite fiber is loosened processing：
Take the 6-14 parts of natural brucite fibers after machinery is loosened with water-reducing agent, water according to 3-5:1:30-50 proportioning mixing, makes
With vane type beater, it is beaten 25-55 minutes with the speed of 200-500r/min, obtains brucite fiber dispersion liquid, it is spare；
（3）Grinding：
By step（1）Active material is sent into lapping device, after 2-5 parts of grinding aids of addition are ground 20-35 minutes, is added above-mentioned
Brucite fiber dispersion liquid, is beaten 8-15 minutes, makes material dispersion uniform；
（4）Mixing：
Again by step（2）Mixture and 10-25 parts of lightweight aggregates, 20-50 parts of cement mixings, are uniformly mixing to obtain thermal insulation mortar.
Wherein, the step（1）High temperature sintering processing is that mixture is placed in 700-800 DEG C of Muffle furnace inside holding 2-4 is small
When.
Wherein, the lightweight aggregate refers to expanded perlite, float stone, glass bead, flyash, bentonite or water-granulated slag
One or more kinds of mixtures.
Wherein, the step（3）Grinding aid includes one kind in triethanolamine, ethylene glycol, glycerine, diethylene glycol (DEG) or octanol
Or multiple combinations.
The present invention has the beneficial effect that：
Pass through high-temperature calcination in the present invention, gangue, slag micropowder are destroyed its original crystal structure, slag by thermal excitation
Structural remodeling, gangue glass net structure cracks, under the action of exciting agent, new thing of the generation with hydraulicity activity
Matter, in heating power with the dual excitation of chemistry, promoting the generation of gum material, makes material that there is higher pozzolanic reaction to live
Property；Brucite fiber is preferably loosened under water-reducing agent effect, and fibre diameter drops to nanoscale, Zhi Hou by micron order
Under the surface-active action of grinding aid, the surface charge of slag and brucite fiber is influenced, has the function that dispersing and disintegrating particle,
Slag powder more refines, and reaches further to split brucite fiber and is allocated as using, and improves point of fiber with slag in the base
The degree of dissipating, is conducive to play the activeness and quietness effect to mortar.
