Material, can be applied directly to surface of wall, its more general decorative mortar has the functions such as light weight, insulation.
In recent years, with the development of China's building energy conservation cause, inorganic heat insulation mortar field there has also been larger development, special
It is not light-weight aggregate, performance preferably glass bead is also developed into based on expanded perlite etc. from traditional.But it is inorganic by these
The thermal insulation mortar of light-weight aggregate production is compared with other organic heat preservation of board materials, and thermal conductivity factor is still larger.China region
Wide, north-south climate situation differs greatly, and in cold and severe cold area, the requirement to building exterior wall heat preserving is higher.Inorganic is protected
Warm mortar heat-insulation layer is only accomplished could be up to standard after certain thickness.But thickness increase, the gross weight of whole heat insulation system increases therewith
Plus, security performance reduction, so the application of inorganic heat insulation mortar also suffers from certain restriction.
But, inorganic heat insulation mortar is due to excellent fire protection flame retarding security performance；Material resources chemical stability is good；It is weather-proof
Property is fabulous, can be with the building same life-span, environmental protection；Easy construction, the advantages of price is relatively low.It is always building heat preservation market
One of kind received much concern.In recent years, many experts, scholar's research inorganic heat insulation mortar each component were to heat-insulating property
Influence, to improve its performance indications.In terms of insulation, thermal conductivity factor is the important indicator of insulation material, therefore chooses
Light-weight aggregate turn into improve conventional vacuum mortar important channel.
In addition, the production technology that conventional thermal insulation mortar production is typically fed intake in due order using single mixer.This production
The advantage of technique is small investment, has the disadvantage that product stability is poor, less efficient, and light-weight aggregate breakage rate is high.
The content of the invention
It is an object of the invention to provide a kind of low heat conductivity heat-insulating mortar, it, as light-weight aggregate, is had using aerogel particle

Polymer glue powder, cellulose ether, high efficiency water reducing agent, organosilicon moisture repellent, wood fibre polymer glue powder add cement or gypsum
It is middle to be pre-mixed, then add double spiral ribbon mixers and stir 3~5min, it is uniform to be sufficiently mixed；（2）Mixture is inputted
In forced action type agravic blender, and add fiber and mixed, stir 3~5min；（3）Finally secondary mixture is inputted light
Gather materials in special-purpose stirring machine, add light-weight aggregate and mixed, stir 2~3min.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is greatly dropped using aeroge as light-weight aggregate
The low thermal conductivity factor of material, and technique is mixed using three-level,（1）Improve the mixture homogeneity of additive；（2）Make fiber
It is sufficiently mixed uniformly, and reduces the fed distance of fibre blend, so as to reduce blocking, improves efficiency；（3）Using Special agitating
Machine is mixed, that is, shortens the mixing time of light-weight aggregate, reduces the breakage of light-weight aggregate, thermal insulation mortar can again fully stirred evenly.
