Description
Technical field
The present invention relates to construction material construction field, in particular to a kind of cement steel wire of magnesia salt cementitious material foaming
Frame insulation board.
Background technique
It largely uses in the civil engineerings such as building, road, bridge, tunnel, airport and dam using calcium salt as hydrated product
Inorganic coagulation material, wherein common calcareous cementitious material includes lime, gypsum, portland cement, aluminate cement and sulphur
Aluminate cement, calcareous cementitious material are that the development of modern civil engineering is made that major contribution.Calcareous glue currently on the market
Gel material does the cement foam board majority manufactured using lime, gypsum and portland cement as primary raw material, which has early stage
The disadvantages of intensity is relatively high, and later strength decaying is big, and poor thermal insulation property, intensity is low, and durability is poor.
It is similar with calcareous cementitious material, it is there is also using magnesium salts as the another kind of inorganic coagulation material of hydrated product, i.e., magnesia
Cementitious material, common magnesium gelatinous material include magnesia oxychloride cement, magnesium oxysulfide concrete and magnesium phosphate cement.Magnesium is first in the earth
Element composition total amount is only second to the 4th bit element (accounting for 12.7%) after iron, oxygen, silicon, and raw material sources are more than calcareous cementitious material
Add abundant.Magnesia oxychloride cement is french chemist S.Sorel invention in 1867, is that activity MgO and certain density magnesium chloride are molten
The MgO-MgCl of liquid composition2-H2O ternary system air hardening cementitious materials.With the tool of the invention of Britain mason J.Aspdin in 1824
There is the Portland cement (i.e. portland cement) of the hydraulicity to compare, magnesia oxychloride cement has light, fast solidifying, early strong, high-strength, low
Alkali, the advantages that wear-resisting, adhesion strength is high, the corrosion of salt resistance halogen, but it is there are water-resistance poor, easy damp suction surface halide accumulation, easily-deformable and corrode
The disadvantages of steel wire.Magnesium oxysulfide concrete is the magnesium gelatinous material similar with Properties of Magnesium Oxychloride Cement, by active MgO and a certain concentration
MgSO4The MgO-MgSO of solution composition4-H2O ternary system air hardening cementitious materials.Magnesium oxysulfide concrete and magnesia oxychloride cement phase
Than still there is obviously advantage, as its high temperature resistant property is good, the nonhygroscopic halogen, small to steel wire action of rust of returning.Magnesium phosphate
A kind of air-setting gelling material that cement is made of dead burned magnesia powder, soluble phosphate and inducer (such as retarder)
Material, good, adhesion strength high abrasion, the rust-preventing characteristic to steel wire with solidifying, early strong, high-strength, freeze proof, high temperature resistant, volume stability fastly
Can it is good the advantages that, the disadvantage is that it is at high cost, need to consume phosphor resource.In three big magnesium gelatinous materials, magnesium oxysulfide concrete is that most have
Wish successfully to replace magnesia oxychloride cement and occupies the novel gelled material of greater share in architectural engineering industry.Currently, being directed to
The disadvantage that magnesium oxysulfide concrete intensity is not high, aquation is insufficient, which improves and cement plate is made, realizes that industrialization also rarely has registration.
