Description

A kind of composite thermal insulation mortar

Technical field

The present invention relates to thermal insulation mortar field, is exactly a kind of composite thermal insulation mortar.

Background technology

Inorganic heat insulation mortar (glass bead Fireproof thermal insulation mortar; complex silicate aluminium thermal insulation mortar) be a kind of novel heat-preserving energy-saving mortar material whitewashed for buildings inner-outer wall; using inorganic glass bead (also known as closed-cell expanded perlite) as light skeletal, add the dry-mix be made up of gelling material, anticrack additive and other stopping composition etc.There is the feature such as excellent properties and cheap price that energy-conserving profit waste, heat insulating, fire prevention are antifreeze, ageing-resistant, have the market requirement widely.

Summary of the invention

The object of the present invention is to provide a kind of composite thermal insulation mortar.

Above-mentioned purpose is realized by following scheme:

A kind of composite thermal insulation mortar, is characterized in that: it is obtained by the raw material of following weight parts:

Glass bead 60-70, desulfurated plaster 10-16,42.5 class g cement 380-400, redispersable latex powder 10-15, gypsum tailings 3-5, rapeseed cake 2-4, sugared calcium water reducer 3-5, polypropylene fibre 1-2, metakaolin 4-6, milling type steel fibers 1-2, waterproofing agent of organosilicon 1-2, zeolite 6-8.

Described a kind of composite thermal insulation mortar, is characterized in that:

Preparation method is:

(1) zeolite fragmentation is got, abrasive dust, cross 80-100 mesh sieve, 1-2 days is soaked again in deionized water, take out, dry, add again be equivalent to its weight 0.3-0.5% trioctyl trimellitate, 0.2-0.4% the antioxidant 1076 of oxidation inhibitor T501,0.3-0.8%, and appropriate water, stir 10-15 minute under 100-200 rev/min after, after adding the butadiene-styrene latex mixing being equivalent to its weight 1-2%, granulation, balling-up particle diameter at 0.5-1mm, then calcines 1-2 hour at 200-300 DEG C, takes out and to obtain modified zeolite particle for subsequent use;

(2) glass bead, 42.5 class g cements, gypsum tailings are mixed by weight; 3-5 minute is stirred under 600-700 rev/min; take out, then with the whole raw material blending of residue after, then add in kneader; 1-2 hour is incubated at 60-70 DEG C; take out, add suitable quantity of water, stir; the material three-roll grinder grinding 2-3 hour that will be stirred again, after packaging and get final product.

Beneficial effect of the present invention is: the present invention possesses good heat-accumulation temperature-adjustment ability and waterproof ability, is applicable to the wall thermal insulating engineering construction of all kinds of buildings, also can meets certain requirement of strength.

Embodiment

A kind of composite thermal insulation mortar, it is obtained by the raw material of following weight kg:

Glass bead 70, desulfurated plaster 16,42.5 class g cement 400, redispersable latex powder 15, gypsum tailings 5, rapeseed cake 4, sugared calcium water reducer 5, polypropylene fibre 2, metakaolin 6, milling type steel fibers 2, waterproofing agent of organosilicon 2, zeolite 8.

Described a kind of composite thermal insulation mortar, preparation method is:

A () gets zeolite fragmentation, abrasive dust, crosses 100 mesh sieves, soak 2 days in deionized water again, take out, dry, add the trioctyl trimellitate, the oxidation inhibitor T501 of 0.4%, the antioxidant 1076 of 0.5% that are equivalent to its weight 0.5% again, and appropriate water, stir after 15 minutes under 200 revs/min, after adding the butadiene-styrene latex mixing being equivalent to its weight 2%, granulation, balling-up particle diameter at 0.5-1mm, then is calcined 2 hours at 300 DEG C, takes out and to obtain modified zeolite particle for subsequent use;

(2) by the kg proportioning mixing by weight of glass bead, 42.5 class g cements, gypsum tailings; stir 5 minutes under 700 revs/min; take out, then with the whole raw material blending of residue after, then add in kneader; 2 hours are incubated at 70 DEG C; take out, add suitable quantity of water, stir; again the material three-roll grinder be stirred is ground 3 hours, after packaging and get final product.

Products obtained therefrom test result is as follows:
