Technical field

The present invention relates to building slurry fields more particularly to a kind of wall thermal insulating slurry and preparation method thereof.

Background technique

Wall thermal insulating slurry is the novel wall material developed in recent years, can largely save materials for wall, improves wall and protects Warm nature energy, economizes on resources, and reduces environmental pollution.With carrying out in a deep going way for Building Energy-saving Work, external walls heating insulation newly-built and Carry out extensively in extending old building engineering.Energy conservation project is made, really realizes that energy saving key is to select good heat preservation slurry.

Summary of the invention

For the shortcomings of the prior art, the present invention provides wall thermal insulating made of a kind of selection various materials Slurry can satisfy the demands such as house, heat supply pipeline, industrial equipment.

To achieve the above object, the present invention provides a kind of wall thermal insulating slurry, divides according to mass ratio, including below at Point:

Perlite 1-5%；

Bentonite 5-10%；

Vermiculite power 0.3-0.9%；

Fast penetrant T 0.5-0.875%;

Sodium silicate solution 5-10%；

Alumina silicate fibre 0.7-1.5%；

Thixotropic agent: 0.5-0.875%；

Sawdust powder: 1-5%；

Aluminate cement 10-20%；

Water surplus.

Preferably, being divided according to mass ratio, including following component:

Perlite: 2.3-3.7%；

Bentonite 7-9%；

Vermiculite power 0.5-0.75%；

Fast penetrant T 0.6-0.75%;

Preferably, the perlite is level-one perlite.

Preferably, the bentonite is organobentonite.

Preferably, the thixotropic agent is one of precipitated silica and kaolin.

Preferably, the concentration of the sodium silicate solution is 8-10%.

The invention also discloses a kind of preparation methods of wall thermal insulating slurry, weigh perlite, swelling respectively according to quality They are done dry or the pre-heat treatment, so by soil, vermiculite power, alumina silicate fibre, fast penetrant T, sawdust powder and thixotropic agent respectively Bentonite, vermiculite power, perlite, thixotropic agent and sawdust powder are put into afterwards and stir 20-30 min in blender, until stirring is equal It is even, mixed slurry A is obtained, fast penetrant T and alumina silicate fibre are individually packed, obtains slurry B;

Preferably, being firstly added slurry B in water, mixed slurry A and sodium silicate solution are put into after sufficiently impregnating, stirs 20- 30min puts into aluminate cement again after mixing evenly, then is stirred 10-15min, and the slurry mixed uses in 6 hours It finishes.

The beneficial effects of the present invention are: slurry of the present invention is answered by various ingredients such as perlite, the bentonites of low thermal conductivity It closes, forms closed micropore in material internal, so that the unit mass of whole slurry substantially reduces, and filled in these micropores Expire the weaker air of heat-conductive characteristic, so as to effectively organize the transmitting of heat, reaches good heat insulation and preservation effect；This Shen Please provided by the thermal coefficient of wall thermal insulating slurry be 0.065w/ m k, heat insulating effect is significant, and soundproof effect is good, In 600 DEG C under conditions of constant temperature 4 hours, can still bear the pulling force of 100kpa, and tensile strength is high, and adhesion strength can reach 31kpa, It is a kind of good energy conservation and environmental protection construction material.

Detailed description of the invention

Fig. 1 is national inspection centers examining report.

Specific embodiment

In order to more clearly state the present invention, the present invention is further described below with reference to embodiment.

It since slurry is a kind of unsetting high mucilage material, can be attached directly on various industrial equipments, cohesive force is big, insulation Performance is good, and intensity is greater than cement pearl and cement vermiculite heat preservation slurry again, and insulation thickness is small, therefore can overcome conventional vacuum material completely The shortcomings that material, materials save, and insulation thickness is greatly reduced than traditional material, every to be starched using 1 cubic metre of heat preservation, can save mark every year Quasi- coal 20-30 tons.

The slurry can arbitrarily shape, and be very suitable for the anisotropic equipment such as elbow, valve, rotary body, sphere and construction wall Heat-insulated, heat preservation, can be realized integral sealing, substantially increases insulation coverage rate.

The slurry is nontoxic, pollution-free, specious, and cold conditions, hot heat power equipment are smearable, does not influence equipment fortune Row, construction and maintenance are convenient, are convenient for metal defect detection, reduce maintenance Thermal insulation Expense, house insulation and torrid areas to cold district House is heat-insulated also to reach good effect.The slurry sound insulation value is good, and being applied to the surfaces such as equipment, building can also be significantly Reduce ambient noise.

The slurry shrinking percentage is small, and smearing maximum contraction rate is 16.4%, particularly suitable for storing furnace, tank body tank seam；Solidification Fastly, final set is not more than 24 hours, and because belonging to the small solidification of hygrometric state situation, therefore water-resistance is strong, can also be fabricated to heat insulation profile, heat preservation Sound insulation profile etc..

It is elaborated below using preparing gross mass for the slurry of 10kg as specific embodiment.
