Background technology
Magnesium oxysulfide Binder Materials, also known as magnesium oxysulfide concrete, is the base material of above-mentioned novel latex composite material.This kind of gelling material
Material is at MgSO4, MgO and H2O mixing preparation according to a certain percentage becomes MgSO4-MgO-H2On the basis of O ternary system, then through filling
Aquation is divided to be formed with xMg (OH)2·yMgSO4·zH2O is the Binder Materials of main component.Compared with magnesia oxychloride cement, magnesium oxysulfide
Cement with magnesium sulfate as blender, fundamentally solve magnesia oxychloride cement because of chloride ion transport cause to surface to return halogen general
Frost, corrosion reinforcing bar, poor water resistance, strength retraction and environment is had the defects such as harm.Meanwhile, magnesium sulfate mostly is chemical industry, metallurgy, electricity
The converting waste material of the industry such as power, environmental protection prepares, and while reducing production cost, efficiently solves again asking of environmental pollution
Topic, meets the production requirement of green chemical industry.Composite modifier described in base material prepared by method described above and claims,
Trade waste and fiberfill are combined, and i.e. generate magnesium oxysulfide latex composite material.
But the magnesium oxysulfide that prior art produces and chlorine oxygen magnesium gelling composite board generally exist, and mechanical strength is relatively low, resistance to water
Inadequate and easy buckling deformation and the problem such as service life is short, therefore, the present invention to magnesium oxysulfide composite gelled material from material mixture ratio,
Preparation technology and modifying agent add three aspects and carry out Improvement, have prepared a kind of property that may be used for Prefabricated heat-insulation wall plate
Can superior, Environmental Safety and there is the magnesial latex composite material of high value of practical.
Summary of the invention
It is an object of the invention to solve that the intensity that the magnesium oxysulfide sheet material that above-mentioned prior art produces exists is low, resistance to water
The defects such as difference, buckling deformation, it is provided that a kind of magnesium oxysulfide latex composite material formula that may be used for Prefabricated heat-insulation wall plate and system thereof
Preparation Method.
The present invention implements by the following technical programs:

Described composite modifier is composited by weight by following components:
The preparation method of the described magnesium oxysulfide latex composite material for Prefabricated heat-insulation wall plate, comprises the steps:
A, Magnesium sulfate heptahydrate is configured to aqueous solution, adds light calcined magnesia and powder filler, add successively after stirring 5min
Enter composite modifier and fiberfill, continue stirring 10-30min, obtain described magnesium oxysulfide latex composite material slip.
B, above-mentioned gained slip is poured in the mould paving fiberglass gridding cloth or non-woven fabrics, seal and be placed in 25-
40 DEG C, the demoulding after maintenance 6-16 hour in the fog room of relative humidity 50-70%, continues sealed maintenance and transfers to after 7 days after the demoulding
Natural curing was to 28 days.
The magnesium oxysulfide latex composite material formula that the present invention provides adds powder filler and fiberfill, improves plate
The toughness of material, and by adding composite modifier, it is greatly improved intensity and the resistance to water of magnesium oxysulfide latex composite material,
Reduce the production cost of Prefabricated heat-insulation wall plate to a certain extent.Use the Prefabricated heat-insulation wall plate of gained of the present invention without buckling deformation
With problems such as scummings, its intensity and resistance to water the most relatively prior art has the biggest lifting simultaneously.
