From social energy consumption structure, whole world energy for building is 1/3 left and right of Danone source total amount consumed; And the raising along with living standards of the people is progressively increased.In all building energy consumptions, the energy consumption proportion of architectural exterior-protecting construction is larger.And exterior wall area accounts for the major part of building enclosure, therefore, the thermal insulation technology of exterior wall is processed reducing building energy consumption and improving indoor comfort relation very large, and External Walls Heating Insulation is arisen at the historic moment.And the basis of External Walls Heating Insulation is exactly kind and the quality of external-wall heat-insulation material.
Conventional external-wall heat-insulation material is generally at present: styrofoam or polyurethane sheet that organism is manufactured, and their feature is adiabatic good heat-insulation effect, cost is low, but it is dangerous to be easy to catch fire, and progressively eliminates.Though rock wool heat-preservation material is inorganic materials, missing of ignition.But there is the shortcoming of three-dimensional intensity anisotropy.Use difficulty larger.
Three, summary of the invention
The object of the invention is in order to improve the deficiencies in the prior art, the fire resistance that makes full use of ceramic provides a kind of combined techniques to manufacture architecture exterior wall insulating materials.
Another object of the present invention is its manufacture method.
The object of the invention is to complete like this: it comprises the manufacture method of manufacturing architecture exterior wall insulating materials and lagging material with combined techniques, raw material is that aggregate, high temperature adhesives and low-temperature binder form, described aggregate is pearlstone, expanded vermiculite, float stone, swelling clay, heaving shales, expansion volcanic ash and through overexpansion, the raw material that contains a large amount of pores; High temperature adhesives is by weight ratio: SiO 245～60%, Al 2o 34～8%, CaO 10～15%, B 2o 35～12%, Na 2o 1～8%, K 2o 1～8%, and ZnO 1～4%; Low-temperature binder is water glass, wilkinite.
A kind of combined techniques of the present invention is manufactured the manufacture method of architecture exterior wall insulating materials:
1, aggregate is selected: select one or more in aggregate pearlstone, expanded vermiculite, float stone, swelling clay, heaving shales, expansion volcanic ash, be crushed to the particle of 0.1～3 millimeter;
2, high temperature adhesives is processed: high temperature adhesives is crushed to 325 order fine powders;
3, make compound: according to weight ratio: 100 parts, aggregate, 20～50 parts of high temperature adhesives, by aggregate, high temperature adhesives stirs, and makes compound;
4, make low temperature bond agent solution: according to weight ratio: 100 parts, water, 3～10 parts of low-temperature binders, are added to the water low-temperature binder to stir and make low temperature bond agent solution;
5, forming ingredient: by 100 parts of compounds, the ratio that low temperature bond agent solution is 50～160 parts is stirred according to weight ratio; By the admixtion stirring, put into press, compression moulding is tabular;
6, burn till: the plate body of forming is put into kiln, at 700～900 ℃, burn till.
Feature of the present invention:
1, size in plate body making processes, be out of shape easy to controlly, be better than current foaming kind light heat insulation material.
2, thermal conductivity can be controlled, by selecting raw material just can control required thermal conductivity.And foaming kind will be controlled thermal conductivity by series of process parameters such as firing temperatures.
3, firing temperature is low.Owing to selecting meltable bonding agent, sintering is completed at a lower temperature, compared with foamed ceramic, multicellular glass, sintering temperature declines 250～500 ℃.
4, in board materials production, use roller kiln flaming directly to burn, do not need the kiln furniture materials such as backing plate, saggar, burn till heat utilization rate higher.
