Abstract

The invention discloses a polymer cement waterproof thermal insulation mortar used on external walls of buildings. A waterproof thermal insulation material and the like are added in the preparation of the mortar. Each 300 grams of the mortar comprises the following main materials by mass: 100 grams of ordinary portland cement, 20 grams of secondary fly ash, 20 grams of 200-mesh hydrated lime, and150 grams of 50 to 70-mesh vitrified micro-beads with the dry density of 110 kg/m3; the mortar comprises the following additives mixed with the 300 grams of the main materials by mass: 6 to 9 grams of re-dispersible polymer rubber powder, 1 to 4 grams of methyl cellulose ether, 0.4 to 1.0 gram of long polypropylene fiber of 9 millimeters, 15 to 20 grams of organic silicon powder, and 15 to 20 grams of zinc stearate powder; the main materials and additives are mixed together, and the mixture is bagged for use. Tests on the polymer cement waterproof thermal insulation mortar show that: after 28days, the compression strength is more than or equal to 0.2 MPa, the thermal conductivity is less than or equal to 0.07 W/(m.k), the dry density is less than or equal to 400 kg/m3, and the water absorption is less than or equal to 1,000 g/m2 in 1 hour and is better than that of 5,000 g/m<2> of an external wall mortar of a common material in 1 hour, so the polymer cement waterproof thermal insulation mortar is a novel building material.

Description

A kind of polymer cement waterproof thermal insulation mortar
Technical field
A kind of polymer cement waterproof thermal insulation mortar that the present invention relates to use on the external wall belongs to material of construction.
Background technology
The common inorganic heat insulation mortar material of the general use of the external-wall heat-insulation material of present regional architecture thing cold in winter and hot in summer, but because the water-absorbent of common inorganic heat insulation mortar is very big, 1 hour water regain can reach more than 5000 grams for every square metre, very easily cause wall crazing for this reason, play drum, come off, cause security-hidden trouble and the work-ing life that influences buildings so that the indoor seepage in house takes place.For this reason, be to improve the skin quality, develop a kind of different with the building thermal insulation material of common use material that had not only had heat insulation function but also had a water resistance and just seem very necessary.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the present invention has added the material with water resistance on the prescription of common building heat preservation mortar for outer wall, and this water resistance material has redispersible polymer rubber powder, organosilicon powder, Zinic stearas powder constituent; The material of thermal and insulating performance has glass bead, and the prescription of this mortar is made up of two parts, and the one, the main raw proportioning; The 2nd, additive formula, two proportionings are mixed the back and are formed polymer cement waterproof thermal insulation mortar of the present invention.
Main raw proportioning of the present invention: by weight, contain ordinary Portland cement 110 grams in per 300 gram main raws, second class powered coal ash 20 grams, 200 order white limes, 20 grams, particle diameter 50-70 order, dry density 110kg/m 3Glass bead 150 gram.
Owing in the main raw proportioning, adopted the glass bead of thermal and insulating performance and total amount to account for half, thereby had good heat insulation effect.
The proportioning of additive: by weight, with above-mentioned 300 gram main raws mutually the blended additive contain redispersible polymer rubber powder 6-9 gram, methyl cellulose ether 1-4 gram, the long polypropylene fibre 0.4-1 of 9mm restrains, organosilicon powder 15-20 gram, Zinic stearas powder 15-20 gram is formed.
In the proportioning of additive, redispersible polymer rubber powder, organosilicon powder, Zinic stearas powder have been adopted, so have good waterproof effect with water resistance.
After above-mentioned two proportionings mixing, be polymer cement waterproof thermal insulation mortar of the present invention.
The present invention can reach following performance after tested: 28 days ultimate compression strength 〉=0.2Mpa, thermal conductivity≤0.07W/ (mk), dry density≤400kg/m 3, 1 hour water regain≤1000g/m 2, obviously be better than 1 hour water regain 5000g/m of common heat preservation mortar for outer wall material 2, can promote the construction quality and the work-ing life in house, help promoting, using.
Specific embodiment
Embodiment 1:
The main raw proportioning by weight, contains ordinary Portland cement 110 grams in per 300 gram main raws, second class powered coal ash 20 grams, 200 order white limes, 20 grams, particle diameter 50 orders, dry density 110kg/m 3Glass bead 150 gram;
Additive formula: by weight, with above-mentioned 300 gram main raws mutually the blended additive contain redispersible polymer rubber powder 6 gram, methyl cellulose ether 1 gram, long polyethylene fibre 0.4 gram of 9mm, organosilicon powder 15 grams, Zinic stearas powder 15 restrains.
More than two proportionings mix the back pack and use.
Embodiment 2:
The main raw proportioning by weight, contains ordinary Portland cement 110 grams in per 300 gram main raws, second class powered coal ash 20 grams, 200 order white limes, 20 grams, particle diameter 60 orders, dry density 110kg/m 3Glass bead 150 gram;
Additive formula: by weight, with above-mentioned 300 gram main raws mutually the blended additive contain redispersible polymer rubber powder 7.5 gram, methyl cellulose ether 2.5 grams, long polyethylene fibre 0.7 gram of 9mm, organosilicon powder 17.5 grams, Zinic stearas powder 17.5 restrains.
More than two proportionings mix the back pack and use.
Embodiment 3:
The main raw proportioning by weight, contains ordinary Portland cement 110 grams in per 300 gram main raws, second class powered coal ash 20 grams, 200 order white limes, 20 grams, particle diameter 70 orders, dry density 110kg/m 3Glass bead 150 gram;
Additive formula: by weight, with above-mentioned 300 gram main raws mutually the blended additive contain redispersible polymer rubber powder 9 gram, methyl cellulose ether 4 grams, long polyethylene fibre 1 gram of 9mm, organosilicon powder 20 grams, Zinic stearas powder 20 restrains.
More than two proportionings mix the back pack and use.
The present invention has been owing to added waterproof and lagging material in material, thereby uses when exterior wall, has better waterproof, heat-insulating property than common thermal insulation mortar material, and water regain has only 1000 gram/m when also having proved its 1 water after tested 2, obviously be better than 1 hour water regain 5000g/m of common material 2, the quality of body of wall has been had large increase.
