The physical and mechanical properties in product are built, a kind of novel acid-resistant anti-corrosion material is formed；It is comprehensive that the composite material can increase ardealite
Close utilization ways and a large amount of consumption ardealites；The composite material can correspondingly improve water resistance, reach outdoor municipal works
Requirement.
For deficiency above-mentioned in the prior art, the second object of the present invention is the provision of one kind using ardealite as base material
Advanced composite material (ACM) preparation method；The preparation method design science, it is easy to operate, it is suitable for large-scale industrial production.
In order to achieve the above object, the solution that the present invention uses is：
It is a kind of using ardealite as the advanced composite material (ACM) of base material, raw material in parts by weight, including：1 part of ardealite,
0.03-0.05 parts of 0.85-0.95 parts of slag and sodium hydroxide.
It is a kind of such as above-mentioned using ardealite as the preparation method of the advanced composite material (ACM) of base material, including：By ardealite, slag with
And mixture is formed after sodium hydroxide mixing, water, the mass ratio 188-200 of mixture and water are added into mixture：120, it supports
Shield 3 days.
It is provided by the invention a kind of to be by the advantageous effect of the advanced composite material (ACM) of base material and preparation method thereof of ardealite：
(1) present invention, by being compounded with slag and sodium hydroxide, is creatively researched and developed using ardealite as primary raw material
A kind of hydraulicity gelling composite material with higher-strength is gone out.The composite material can substitute common portland cement
Used as construction material, can not only consume a large amount of ardealites, and meet the energy saving, emission reduction of country's proposition, consumption reduction economy
Developing direction；The rational utilization of resource is of great significance to the sustainable development of China's phosphorus chemical industry and building materials industry.This
Ardealite is taken in invention：Slag：Sodium hydroxide is compounded according to above-mentioned parts by weight so that the coefficient of softing of gypsum base is by passing
The 0.6 of system is increased to 0.8, has correspondingly improved water resistance, has reached outdoor municipal works requirement.In addition, material of the present invention
Expect production cost at 150 yuan/ton hereinafter, nearly 200 yuan/ton or so of selling cost, market prospects are good.
(2) present invention is simple and efficient by the preparation method design science of the advanced composite material (ACM) of base material of ardealite, each anti-
Coordinated between condition is answered, physical property, mechanical property can be prepared and water resistance is excellent is with ardealite
The advanced composite material (ACM) of base material.
Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
Below to provided in an embodiment of the present invention a kind of using ardealite as advanced composite material (ACM) of base material and preparation method thereof
It is specifically described.
It is a kind of using ardealite as the advanced composite material (ACM) of base material, raw material in parts by weight, including：1 part of ardealite,
0.03-0.05 parts of 0.85-0.95 parts of slag and sodium hydroxide.
The selection of above-mentioned each raw material and proportioning pass through scientific design, so that association can be played by cooperating between various raw materials
With the effect of synergy, using this proportioning, can greatly improve the physical property of the advanced composite material (ACM) of preparation, mechanical property and
Water resistance.
Further, inventor's creatively hair style, when in parts by weight, ardealite is 1 part, slag 0.85-
When 0.9 part and sodium hydroxide are 0.03-0.04 parts, the physical property of the advanced composite material (ACM) being prepared, mechanical property and
Water resistance is more excellent.When in parts by weight, ardealite is 1 part, and slag is 0.85 part and sodium hydroxide is 0.04
Part when, the physical property of the advanced composite material (ACM) being prepared, mechanical property and water resistance are the most excellent.
It should be noted that in the present embodiment, the phosphorus stone generated when ardealite is using production high-concentration phosphate compound fertilizers
Cream；The slag uses the Iron-ore Slag of steel plant's production, in favor of saving cost, refuse reclamation.Sodium hydroxide is using saturation
The supernatant of sodium hydroxide solution after precipitation.There is very strong water imbibition due to sodium hydroxide and easily absorb in air
CO2, therefore often contain Na in commercially available sodium hydroxide2CO3。Na2CO3It is affected to using, needs to remove.Due to Na2CO3
It is not almost dissolved in saturation sodium hydroxide solution, can slowly be precipitated out, therefore, in the present embodiment, first match sodium hydroxide
At saturated solution, Na is waited for2CO3After precipitation, then Aspirate supernatant.
In the present embodiment, the attached water of ardealite be less than 10% wet-milling, the pH=2-5 of ardealite, ardealite it is water-soluble
Property fluorine<0.5% and ardealite grain size be less than 50 μm；The control of the performance indicator of above-mentioned ardealite is conducive in ardealite
Active principle give full play to, in favor of carrying out sufficient compound synergic with other raw materials.
In the present embodiment, the detection moisture content of Iron-ore Slag is less than 2%, and the butt solid formation content of Iron-ore Slag is more than
95%.The active principle that the control of the performance indicator of above-mentioned Iron-ore Slag is conducive in Iron-ore Slag gives full play to, in favor of with other
Raw material carries out sufficient compound synergic.In the present embodiment, the size controlling of Iron-ore Slag is 0.04-0.06mm；Further subway
The size controlling of slag is 0.05mm, so that the active principle in Iron-ore Slag fully plays, and is conducive to Iron-ore Slag and its
He is adequately mixed raw material.
It is a kind of using ardealite as the preparation method of the advanced composite material (ACM) of base material, including：By the phosphorus stone of above-mentioned quality proportioning
Mixture is formed after cream, slag and sodium hydroxide mixing, water, the mass ratio 188- of mixture and water are added into mixture
200：120, it conserves 3 days.It is conserved, advanced composite material (ACM) obtained, is had using the quality proportioning of said mixture and water
