Abstract
The invention discloses a kind of fire resisting light-weight aggregate, the light-weight aggregate composition includes：The mass parts of vermiculite 20 ~ 25, the mass parts of haydite 22 ~ 27, the mass parts of adobe clinker 21 ~ 24, the mass parts of hollow alumina ball 23 ~ 26, binding agent.
Description
Technical field
The present invention relates to light-weight aggregate field, more particularly to a kind of fire resisting light-weight aggregate.
Background technology
Insulating materials can be divided into it is organic and inorganic two kinds of, organic insulation be usually predominantly XPS or
Granules of polystyrene slurry.One big problem is the difference between anti-styrofoam fire protecting performance, although being used in building insulating layer
Fire-retardant styrofoam, but also have certain self-extinguishment, a large amount of toxic gases gross distortion in case of fire can be produced after heated, is made
Into personal injury and damage building insulating layer, cause running into fire-fighting difficulty.
Based on organic material point really, the present invention is on the basis of existing organic material is studied, it is proposed that a kind of fire resisting is light
Gather materials, not only fire resistance is good, and this light-weight aggregate carries out not damaged under burning condition to human body.
The content of the invention
The present invention is on the basis of existing organic material is studied, it is proposed that and a kind of fire resisting light-weight aggregate, not only fire resistance is good,
And this light-weight aggregate carries out not damaged under burning condition to human body.One technical scheme of this use is：There is provided a kind of resistance to
Fiery light-weight aggregate, it is characterised in that the light-weight aggregate composition includes：The mass parts of vermiculite 20 ~ 25, the mass parts of haydite 22 ~ 27, adobe
The mass parts of clinker 21 ~ 24, the mass parts of hollow alumina ball 23 ~ 26, binding agent.
Further, the binding agent is selected from alumina cement, sodium metasilicate, one kind of sodium phosphate or mixture.
Further, the binding agent is the mixture of alumina cement and sodium phosphate.
Further, the mixture of the alumina cement and sodium phosphate is the mass parts of alumina cement 6, the mass parts of sodium phosphate 10.
Further, the light-weight aggregate composition includes：The mass parts of vermiculite 23, the mass parts of haydite 25, the matter of adobe clinker 23
Measure part, the mass parts of hollow alumina ball 25.
The beneficial effects of the invention are as follows：The situation of prior art is different from, light-weight aggregate meets fiery non-ignitable, combustibility height, tool
There is cost small, thermal conductivity factor is low, and bearing capacity is high.
