Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of its preparation side of novel wall flame-proof thermal insulation material
Method.
Background technology
In the face of the energy problem of whole world growing tension, energy-conservation being paid much attention to by national governments, developed country is from 20 generation
Record and act the problem beginning to pay close attention to building energy conservation the seventies.Building energy conservation refers to by taking rational architectural design and selecting symbol
Close the measure such as the materials for wall of power conservation requirement, roof insulation material, door and window, air-conditioning, the house so built, and do not take
The house of conservation measures is compared, and under the conditions of ensureing identical indoor thermal comfort environment of rural, it can improve efficiency, subtracts
Few building energy consumption.
Research data shows, the heat for building house consumes main two parts composition, i.e. the heat transfer of building enclosure disappears
The air penetration of the positions such as consumption and door-window opening consumes composition.The former account for more than the 75% of enclosed structure heat transfer consumption, the latter
Account for about 25%.Such that it is able to know that the key position of building energy conservation is building enclosure in whole building structure, carries out and goes along with sb. to guard him
The energy conservation of structure becomes most important, and in building maintenance structure, body of wall account for major part, therefore building outer wall
Insulation is one of important way of building energy conservation realization.
Materials for wall consumption shelter has first of construction material under construction, reaches 70%, and traditional wall heat insulation material
There is all defects and deficiency.Along with building develops to high level, alleviate the deadweight of materials for wall and improve its insulation joint
Can effect, and meet fire protection requirement become materials for wall reform and development direction.
Summary of the invention
For solving the problem that prior art exists, the present invention provides a kind of its preparation side of novel wall flame-proof thermal insulation material
Method, has the premium properties such as insulation, lightweight, fire-resistant, waterproof, high-strength, lower shrinkage.
For achieving the above object, the technical solution used in the present invention is:
A kind of novel wall flame-proof thermal insulation material, including the component of following precentagewise mixing:
Sulfur lemon magnesium cement cementitious 55 ~ 85%；
Light thermal-insulation aggregate 10 ~ 30%；
Foaming agent 3 ~ 9%；
Hydrophober 0.4 ~ 1.2%；
Anti-crack fiber 0.4 ~ 0.6%.
What described sulfur lemon magnesium was cement cementitious be grouped point includes light calcined magnesia, Magnesium sulfate heptahydrate, water and citric acid, described
The mass ratio of light calcined magnesia and Magnesium sulfate heptahydrate is 1.7, and water and Magnesium sulfate heptahydrate mass ratio are 1.0, citric acid and light-burned oxygen
The mass ratio changing magnesium is 1.3%.
In described light calcined magnesia, the content of magnesium oxide is more than 85%.
Described light thermal-insulation aggregate is glass bead, and granularity is 0.5 ~ 1.5mm.
Described foaming agent is hydrogen peroxide.
Described hydrophober is powder type waterproofing agent of organosilicon.
Described anti-crack fiber is polypropene staple, a length of 9mm.
The preparation method of described a kind of novel wall flame-proof thermal insulation material, including step in detail below:
(1) it is first according to above-mentioned quality proportioning and weighs each component, citric acid and anti-crack fiber C are added to the water stirring 30 seconds, make
Fiber is completely dispersed, and citric acid is dissolved completely in water；
(2) then Magnesium sulfate heptahydrate crystal addition aqueous solution is stirred into uniform magnesium sulfate solution, low rate mixing sulfur
Acid magnesium solution, while adding light calcined magnesia, is treated that light calcined magnesia the most quickly stirs 5 minutes after adding, is stirred into uniform
Sulfur lemon magnesium cement paste；
(3) glass bead is finally added, hydrophober A and hydrogen peroxide, stir 30 seconds；
(4) being injected in time in wallboard by the slurry mixed and stirred, under the conditions of 25 DEG C, sealed maintenance is to 28d age.
Beneficial effects of the present invention:
The vitrified microsphere insulating material that the present invention uses compensate for traditional granular polystyrene and normal expanded perlite in performance
Many defects in lightweight aggregate insulation material and deficiency, overcome the efflorescence big, easy of expanded perlite lightweight aggregate water absorption, in construction
The defects such as middle cubical contraction is big, easily cause that product later strength is low and hollowing cracking and reduce the drawbacks such as heat-insulating property, simultaneously
Compensate for that granular polystyrene organic material is inflammable, fire line is poor, high temperature time produce harmful gas and weatherability is poor, construction bounce-back greatly etc.
Defect.Vitrified microsphere insulating material is a kind of Green Product truly.
The bond that the sulfur lemon magnesium of present invention employing is cement cementitious is strong, intensity is high, slurry denseness is big, pouring stability good,
More bubble and light-weight aggregate can be mixed into and the mould that is difficult to collapse, and still can keep of a relatively high in the case of air pocket volume
Intensity, additionally the density of material of itself is low, is suitable for producing the insulation material of low-density and high-strength.
The sulfur lemon magnesium of present invention employing is cement cementitious is a kind of high refractory material.The refractoriness of magnesite light burnt powder occupies fire proofed wood
The hat of material, reaches 2200 DEG C, and its foaming insulation board can be used for the use environment of more than 1200 DEG C, the cement foamed guarantor of magnesium therefore made
Temperature plate very advantageous in terms of refractory heat-insulating.
The present invention has the premium properties such as insulation, lightweight, fire-resistant, waterproof, high-strength, lower shrinkage, is a kind of novel body of wall
Material.
