Description

A kind of anti-cracking heat insulation mortar

Technical field

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

Background technology

Thermal insulation mortar is with various light material for aggregate, is gelating material, admixes some property-modifying additives with cement, is uniformly mixed and a kind of premixing dry-mix made through manufacturing enterprise.Be mainly used in building exterior wall heat preserving, there is the advantage such as easy construction, good endurance.

Summary of the invention

The object of the present invention is to provide a kind of anti-cracking heat insulation mortar

Above-mentioned purpose is realized by following scheme:

A kind of anti-cracking heat insulation mortar; it is characterized in that: it is obtained by the raw material of following weight parts: calcining desulfurization gypsum powder 50-60, volcanic rock powder 5-8, benzene emulsion 5-8; polyvinyl alcohol 0.1-0.3, citric acid 0.01-0.02, modified Nano wilkinite 15-18; white cement 400-500; river sand 20-50, limestone powder 10-20, Vltra tears 1-2; glass bead 40-50, suitable quantity of water.

Described a kind of anti-cracking heat insulation mortar, is characterized in that:

Preparation method is:

(1) after wilkinite being calcined 3-4 hour at 300-400 DEG C, putting into concentration is again that the hydrochloric acid soln of 5-8% soaks 3-4 hour, take out, dry, add the dibutyl ester, the nano-sized carbon of 0.1-0.2%, the titanate coupling agent YDH-201 of 1-2% that are equivalent to its weight 0.5-0.8%, and appropriate water, stir 10-15 minute under 100-200 rev/min after, take out, dry, after grinding to form nanometer powder, obtain modified Nano wilkinite for subsequent use;

(2) white cement and calcining desulfurization gypsum powder, volcanic rock powder, benzene emulsion are mixed, under room temperature, under 100-200 rev/min, stir 20-30 minute;

(3) add surplus stock by weight again, stir 5-8 minute at 25-30 DEG C, to obtain final product.

Beneficial effect of the present invention is:

The present invention is by the improvement to thermal insulation mortar component, make its cohesiveness good by adding the compositions such as modified Nano wilkinite, benzene emulsion, intensity enhancing, is provided with extraordinary resistance to cleavage, and have good workability, for modern architecture energy-saving material field brings significant progress.

Cohesive strength of the present invention is high, and early strength improves fast, is obviously better than the thermal insulation mortar that ordinary pearl rock is aglite, improves operating efficiency.

Embodiment

A kind of anti-cracking heat insulation mortar; it is obtained by the raw material of following weight parts (kg): calcining desulfurization gypsum powder 60, volcanic rock powder 8, benzene emulsion 8; polyvinyl alcohol 0.3, citric acid 0.02, modified Nano wilkinite 18; white cement 500; river sand 50, limestone powder 20, Vltra tears 2; glass bead 50, suitable quantity of water.

Described a kind of anti-cracking heat insulation mortar, preparation method is:

1) after wilkinite being calcined 4 hours at 400 DEG C, put into again concentration be 8% hydrochloric acid soln soak 4 hours, take out, dry, add the dibutyl ester, the nano-sized carbon of 0.2%, the titanate coupling agent YDH-201 of 2% that are equivalent to its weight 0.8%, and appropriate water, stir under 200 revs/min after 15 minutes, take out, dry, after grinding to form nanometer powder, obtain modified Nano wilkinite for subsequent use;

(2) white cement and calcining desulfurization gypsum powder, volcanic rock powder, benzene emulsion are mixed, under room temperature, stir 30 minutes under 200 revs/min;

(3) add surplus stock by weight again, stir 8 minutes at 30 DEG C, to obtain final product.

Products obtained therefrom test result is as follows:
