Description
Technical field
The present invention relates to cement field, specifically, relate to a kind of modified magnesium oxysulfide concrete and use this sulfur
The magnesium oxysulfide expanded material that oxygen magnesium cement prepares.
Background technology
Energy-conservation and environmental protection is two eternal themes in human social development and technological progress activity, calcareous
Cement all uses " two mill single firing " technique, and power consumption is big, and magnesium cement is by MgO powder and MgCl2
Or MgSO4Aqueous solution is formed, and only MgO powder is by MgCO3Or Mg (OH)2Forging
Prepare after burning, other two magnesium salt solution or from industrial by-products or from industrial waste, thus its
Energy consumption and low in resources consumption.Compared with portland cement, the energy consumption manufacturing magnesia basic salt cement is low perhaps
Many:
1, calcination energy consumption is low, and Portland clinker need to burn till at 1450 DEG C, and magnesia basic salt
The primary raw material MgO powder of cement only need to be by MgCO3It is calcined at about 900 DEG C；
2, grinding energy is low, and in portland cement production, the energy of 10% is more expensive electric energy, is used for
Raw material are levigate and one or two grinding of cement grinding, and raw material and grog are all difficult to levigate.But magnesia alkali
MgO powder in formula salt cement is by MgCO3Grinding is carried out again after decomposition, the most levigate, and
Only need grinding once；
3, need not the processing step of other power consumption, and primary raw material magnesium chloride or magnesium sulfate are again
Industrial by-products.
Magnesium oxysulfide concrete is a kind of inorganic glue being prepared as by Adlerika mix light-magnesite powder
Gel material.Magnesium oxysulfide concrete and magnesia oxychloride cement can be referred to as magnesium cement, have light weight, fire prevention,
Coagula, sound insulation, the feature such as heat insulation.Compare with magnesia oxychloride cement, the heat-resisting property of magnesium oxysulfide concrete
Good, little to reinforcement corrosion.Unmodified magnesium oxysulfide concrete intensity is far below magnesia oxychloride cement, therefore
Limit its popularization and application.Intensity main in unmodified magnesium oxysulfide concrete under room temperature is a kind of alkali formula mutually
Magnesium sulfate (3Mg (OH)2·MgSO4·8H2O, 318 phases), Canada scholar You Ao thinks magnesium oxysulfide
The reason that strength of cement is low is that 318 phase contents are low, has the generation of a large amount of magnesium hydroxide.Generally institute
The magnesium oxysulfide concrete of preparation there will be the phenomenon such as cracking, water-resistance difference, in order to improve magnesium oxysulfide concrete
Character, need to add additive to improve its mechanical performance in magnesium oxysulfide concrete.Patent of invention
200510048574.7 preparations proposing a kind of sulfur lemon magnesium cement, i.e. add Fructus Citri Limoniae in magnesium oxysulfide concrete
Acid can improve the mechanical strength of magnesium oxysulfide concrete.Central South University Deng Dehua teaches in its thesis for the doctorate
Using additive J to improve the character of magnesium oxysulfide concrete, its mechanical performance is also improved largely.
In order to be best understood by premium properties and defect and the reason thereof of magnesium oxysulfide concrete, more both at home and abroad
Enterprise and department of government concerned have put into substantial amounts of fund, have attracted many scholars and engineers and technicians
It is studied, it is intended to preferably this cement material of development and application.Some industrially developed country,
Such as countries such as the U.S., Japan, Germany, France and the former Soviet Unions, by substantial amounts of research, by magnesia
Basic salt cement applications in industrial floor, materials for wall, fire-proof product, fireproof jointing sheath, foam every
The fields such as the binding agent of hot material, concrete and grinding tool, owing to their outward appearance is like marble, will
It makes partition plate and sgraffito etc., and achieved with many patented technologies, these patented technologies exist
Improve the performance of this magnesium oxysulfide concrete to a certain extent.
Magnesium oxysulfide concrete resistance to water has been substantially overcomed not strong, dimensional stability in existing research
The shortcoming such as bad so that the range of application of magnesium oxysulfide concrete is widened, and may be used for the production of expanded material.
Patent 201510137642.0 uses chlorine oxygen magnesium and magnesium oxysulfide complex cement to prepare foamed fireproofing door panel,
There is good resistance to elevated temperatures, but it is not with single magnesium oxysulfide concrete foaming.Patent
201510137604.5 use the foaming of carbon fiber magnesium oxysulfide concrete to be prepared for anti-fire door core board, can be at high temperature
At 1200 DEG C fire-resistant 180 minutes, reach prevent fires flammability and the requirement of safety.But on the whole,
The most less for the research of magnesium oxysulfide concrete foamed products, technology is not mature enough, the most unrealized
Magnesium oxysulfide concrete and the application of foamed products, the present inventor studies for a long period of time magnesium oxysulfide concrete develop sulfur
Oxygen magnesium foamed products, be in a leading position level at home.
In view of this, the special proposition present invention.
