Experimental example 1
The performance of thermal insulation mortar obtained by embodiment 1-12 and comparative example 1-6 is tested, concrete outcome is shown in Table 1.
Film basic performance and heat insulation effect testing result in the embodiment 1-12 of table 1 and comparative example 1-6
From table 1 it follows that comparing comparative example 1-6,1-12 of embodiment of the present invention thermal insulation mortar has preferable guarantor
Warm nature energy, and its adhesion strength, compression strength, water resistance and fire protecting performance are also at higher level.
Wherein, embodiment 2 and the check experiment that embodiment 3 is embodiment 1, embodiment 2 is on the basis of the raw material of embodiment 1
On with the addition of thickener, embodiment 3 is to the addition of thickener and defoamer on the basis of embodiment 1.The addition of thickener can
Further to improve the thixotropy of mortar and water-retaining property, the addition of defoamer can reduce unfavorable shadow of the bubble for mortar performance
Ring.By data in table 1 it can also be seen that the addition of thickener and defoamer is advantageous to the lifting of the combination property of thermal insulation mortar.
Embodiment 5 is the control experiment of embodiment 4, and both differences are the weight fraction of elastomeric propylene yogurt liquid
It is different.From table 1 it follows that the dosage of elastomeric propylene yogurt liquid has a certain impact for the performance of thermal insulation mortar.
Comparative example 1-4 is the contrast experiment of embodiment 3, and five differences are incubated original in the raw material in thermal insulation mortar
The species of material and the difference of dosage.Contrast is understood, when being incubated raw material and being only glass bead and mica powder (comparative example 1), insulation
The thermal conductivity factor of mortar has obvious rising, and heat insulation effect is not good enough, and the adhesion strength of mortar and compression strength have it is different degrees of
Decline.This is probably because glass bead is easily broken, and causes heat insulation effect, adhesion strength and compression strength to decline.
Insulation raw material is glass bead, hollow glass microbead and mica powder used by comparative example 2, because double glazing is micro-
Its thermal conductivity factor of pearl is low, high insulating effect, and all not easily damaged in transport, stirring and work progress, therefore for being incubated sand
The reduction of the thermal conductivity factor of slurry has positive role.
Insulation raw material is glass bead, expanded vermiculite and mica powder used by comparative example 3, and data can from table 1
Go out, the addition of expanded vermiculite is advantageous to the lifting of the heat-insulating property and compression strength of thermal insulation mortar.
Insulation raw material is glass bead, rock wool and mica powder used by comparative example 4.Rock wool is added into mortar, is being increased
Its fire protecting performance is improved while adding mortar heat-insulating property.
Although hollow glass microbead, expanded vermiculite and rock wool have a certain degree of carry for the heat-insulating property of thermal insulation mortar
Effect is risen, but above-mentioned insulation raw material is added in thermal insulation mortar to the lifting of heat insulation effect caused by (embodiment 3) simultaneously
Effect sum is lifted much larger than each raw material.It can be seen that raw material glass bead, hollow glass are respectively incubated in thermal insulation mortar provided by the invention
There is obvious synergistic function between glass microballon, expanded vermiculite, rock wool and mica powder.
Comparative example 5 is the contrast experiment of embodiment 4, and comparative example 5 is not added with flyash on the basis of the raw material of embodiment 4
And silicon ash.It can be seen from the data in Table 1 that the coefficient of softing of the thermal insulation mortar of embodiment 4, apparently higher than comparative example 5, this is mainly
Because flyash and adding for silicon ash can improve mortar after mortar water resistance difference and immersion with the impermeability of reinforced mortar
The problem of easily loose.
Comparative example 6 is the contrast experiment of embodiment 6, and both differences are whether rock wool adds.Embodiment 6 is added with
Rock wool, and it is not added with rock wool in comparative example 6.Influence of the rock wool for thermal insulation mortar is mainly reflected in the fire protecting performance of mortar.
Contrast understands that the addition of rock wool causes thermal insulation mortar to have good fire protecting performance.
Comprehensive to understand, thermal insulation mortar provided in an embodiment of the present invention not only has good heat-insulating property, and it is bonded by force
Degree, compression strength, water resistance and fire protecting performance are also at higher level.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
