Description
Technical field
The present invention relates to building material field, and in particular to a kind of fire-retardant materials for wall of high-strength insulation.
Background technology
With the fast development of industry, economic development is also quite rapid, and the whole world is also increasing to the demand of the energy,
In the total energy consumption increasingly increased, building energy consumption is especially big, accounts for the 11 ~ 25% of total energy consumption, substantial amounts of data and experiment
It is exactly to use heat insulating energy saving material all to show most fast most efficient method.
Now at home and abroad, there is the insulation material of many types.Classify by material, insulation material can be divided into three classes, gold
Belong to insulation material, organic insulation material, inorganic heat insulation material.Metal heat preservation material heat insulation effect is good, and fire resistance is good, but this
Kind material feedstock source is few, expensive, too high as cost for the insulation material of building, it is impossible to extensive use.Organic guarantor
Adiabator heat insulation effect is preferable, cheap, prepares simple, is the insulation material being most widely used at present, but organic heat-insulating
Material is inflammable, and easily produces toxic gas in high temperature, and easy to aging, service life is shorter, when fire occurs, often helps
Long fire spreading, produce more serious consequence.
With the rapid development of science and technology, architectural engineering has a great development, the investment of capital construction rise year by year, it is necessary to
There are the needs that more preferably buildings adapt to architectural engineering development from material, still, in construction material, some old materials
Exist in dead constructions work the amount of labour big, low production efficiency, capital construction cycle be long, building from it is great the shortcomings of, turn into building
The stumbling-block of engineering development.Thus, large panel building particularly light panel frame building system has a great development, novel building material
Expect it is large quantities of emerge in large numbers, effect of raisings one-level sound insulation etc. of the reduction of construction material deadweight, the enhancing of shock resistance, heat-insulating property is wanted
Seek also more and more higher.Its uneven, insufficient strength easy fracture that expands with heat and contract with cold of two existing materials for walls, heat insulating effect is not
It is good, it is therefore necessary to be further improved.
The content of the invention
For prior art, the invention aims to provide a kind of high-strength insulation fire-retardant materials for wall, the wall
Strength of materials height, good heat insulating, heat-proof combustion-resistant performance are superior, and employ sludge as filler, have saved resource, have reduced
Material cost, there is higher practical value and good application prospect.
