Description
Technical field
The invention discloses a kind of kervit microbead insulated sand slurry, belong to building material technical field.
Background technology
At present produced and using using the inorganic light-weight aggregates such as granular polystyrene, expanded perlite, expanded vermiculite, glass bead as
The various thermal insulation mortars of insulation material.Kervit microbead insulated sand slurry is applied than wide in Practical Project among these.Vitreous is micro-
Pearl is a kind of inorganic matter vitreous mineral material, and ore in sand form is broken into by volcanic rock powder, is process by special expanded burning method, product
In irregular orbicule particle, its inside is loose structure, and outer surface is in vitrifying closed state, is a kind of preferably resistance to
High and low temperature light heat-insulating material.Due to its physicochemical property quite stable, so with lightweight, thermal insulation, fire prevention, insulation, environmental protection etc.
Good characteristic.Therefore there is excellent thermal and insulating performance by thermal insulation mortar product of the glass bead as aggregate, compensate for using
Granular polystyrene and normal expanded perlite make many defect and deficiency in other conventional vacuum mortars of aggregate, and it is precious to overcome expansion
The easy efflorescence of pearl rock water imbibition great ﹑, volume receipts mistake rate is big in slurry stirring, easily causes showing for product later stage heat-insulating property reduction
As, while compensate for granular polystyrene organic material Yi Ran ﹑ fire protecting performance Cha ﹑ high temperature again and produce pernicious gas and resistance to ag(e)ing Di ﹑
The defects of workability is poor, least big in construction.
Kervit microbead insulated sand slurry is by glass bead, cement as a kind of new green building heat preserving and insulating material
And the one-component insulating dry powder mortar of additive composition, there is excellent thermal and insulating performance, be widely used in building construction
In heat insulating work.However, the cracking resistance of common kervit microbead insulated sand slurry is poor, kervit microbead insulated sand slurry uses when constructing
Wet work, can produce after wall on mortar it is larger dry contraction, cause thermal insulation mortar to produce crack, make the easy seepage of moisture,
Heat-insulation system thermal property is caused to decline.It is more at present to be improved using organic fiber to prevent kervit microbead insulated sand slurry from ftractureing
Its crack resistance, but because the compatibility of organic fiber and cement etc. is poor, therefore effect of prestressed is undesirable.
Kervit microbead insulated sand slurry is a kind of important thermal insulation mortar occurred in recent years, with polyphenyl particle heat-insulating mortar phase
Than having the characteristics that water-fast, anti-aging, fire prevention, not hollowing.Therefore, the market share of kervit microbead insulated sand slurry exists in recent years
Gradually increase.But because the bulk density of glass bead is bigger than granular polystyrene, heat-insulating property and mechanical property are not as good as polyphenyl
Grain, these shortcomings turn into the weakness in kervit microbead insulated sand slurry technology competition.
Therefore, while solving kervit microbead insulated sand slurry cracking resistance poor, its mechanical property and insulation are improved
Performance, there is positive meaning to broader practice development to kervit microbead insulated sand slurry.
