Description

A kind of magnesium oxysulfide latex composite material for Prefabricated heat-insulation wall plate and preparation method
Technical field
The invention belongs to New Building Materials development field, particularly relate to a kind of magnesium oxysulfide glue for Prefabricated heat-insulation wall plate Solidifying composite and preparation method thereof.
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:
A kind of magnesium oxysulfide latex composite material for Prefabricated heat-insulation wall plate, this latex composite material include following components and Its weight portion:
