Description

A kind of cracking resistance inorganic heat insulation mortar

Technical field

The present invention relates to thermal insulation mortar field, is exactly a kind of cracking resistance inorganic heat insulation mortar.

Background technology

Inorganic heat insulation mortar (glass bead fireproof heat insulating mortar; complex silicate aluminium thermal insulation mortar) be a kind of novel heat-preserving energy-saving mortar material for external rendering in buildings; using inorganic glass bead (claiming again closed-cell expanded perlite) as light skeletal, add the dry-mix being formed by gelling material, anticrack additive and other stopping composition etc.There is antifreeze, the ageing-resistant excellent properties of energy-conserving profit waste, heat insulating, fire prevention and the cheap features such as price, have the market requirement widely.

Summary of the invention

The object of the present invention is to provide a kind of cracking resistance inorganic heat insulation mortar

Above-mentioned purpose realizes by following scheme:

A cracking resistance inorganic heat insulation mortar, is characterized in that: it is that raw material by following weight parts makes:

Slaked lime 5-7, dispersibility latex powder 10-15, glass bead aggregate 67-89, hydroxypropyl methyl cellulose ether 1.2-2.5, cement 250-270, CSA swelling agent 1-3, calcium aluminate 1.5-3, calcium hydroxide 2-4, water glass 2-4, borax 3-5, Manganse Dioxide 1-2, rapeseed cake 3-5; modified silica particles 6-8, suitable quantity of water.

Described a kind of cracking resistance inorganic heat insulation mortar, is characterized in that:

Preparation method is:

(1) get in the hydrochloric acid soln that silicon dioxide powder is 10-15% in concentration and soak 10-15 hour, take out, deionized water wash, dry, add again the Zinc Stearate that is equivalent to its weight 0.3-0.5%, the dysprosium oxide of 0.4-0.6%, the silane coupling agent KH570 of 1.5-1.8%, and appropriate water, under 100-200 rev/min, stir after 10-15 minute, grind again 1-2 hour, add the attapulgite that is equivalent to its weight 3-4%, the diatomite of 1-2%, the benzene emulsion of 3-5%, after mixing, granulation, balling-up particle diameter is at 0.5-1mm, obtain modified silica particles standby,

(2) slaked lime, cement, borax are mixed by weight, under 600-700 rev/min, stir 3-5 minute, take out, again with residue whole raw material blendings after, 100-200 rev/min is at the uniform velocity stirred 20-30 minute, then the material three-roll grinder that is stirred is ground to 1-2 hour, after packing and get final product.

Beneficial effect of the present invention is:

Cracking resistance when the present invention has good heat insulation effect, make product after intensity high, preparation technology is simple.

Described a kind of cracking resistance inorganic heat insulation mortar, preparation method is:

(1) get in the hydrochloric acid soln that silicon dioxide powder is 12% in concentration and soak 12 hours, take out, deionized water wash, dry, add again and be equivalent to the Zinc Stearate of its weight 0.5%, 0.6% dysprosium oxide, 1.8% silane coupling agent KH570, and appropriate water, under 200 revs/min, stir after 15 minutes, grind again 2 hours, add and be equivalent to the attapulgite of its weight 4%, 2% diatomite, 5% benzene emulsion, after mixing, granulation, balling-up particle diameter, at 0.5-1mm, obtains modified silica particles standby;

(2) by slaked lime, cement, borax by weight kg ratio mix, under 700 revs/min, stir 5 minutes, take out, again with residue whole raw material blendings after, 100 revs/min are at the uniform velocity stirred 30 minutes, then the material three-roll grinder that is stirred is ground 2 hours, after packing and get final product.

Products obtained therefrom test result is as follows:
