Abstract

The invention relates to inorganic heat insulating mortar used by light-weight heat insulating brick masonry and a preparation method thereof, wherein, the inorganic heat insulating mortar has the raw material compositions and weight contents of 10-30 parts of fly ash, 15-35 parts of vitreous microballon, 1-8 parts of swell soil, 1-10 parts of lime, 250-400 parts of sand and 100 parts of cement. The preparation method comprises the following steps of: uniformly mixing the fly ash, the sand, the swell soil, the hydrated lime and the cement through a machine, adding the vitreous microballon, uniformly mixing through the machine once again and packing by fixed amount. The inorganic heat insulating mortar has the advantages of high strength, low thermal conductivity and good workability, which can avoid the problems of cracking and 'heat bridge' of the masonry body caused by the use of common masonry mortar when being matched with light-weight heat insulating bricks.

Description

Inorganic heat-insulating mortar for light insulating brick masonry and preparation method thereof
Technical field
The present invention relates to a kind of material of construction, be specifically related to a kind of inorganic heat-insulating mortar for light insulating brick masonry and preparation method thereof.
Background technology
Along with going deep into of work applied in the innovation and the energy saving building of national materials for wall, all kinds of light-weight insulating bricks have obtained using widely, mostly be common masonry mortar but be used for the mortar that light-weight insulating brick builds by laying bricks or stones at present, the unit dry weight of common masonry mortar is generally 1600~1800kg/m 3, thermal conductivity is 0.8~1.1W/mK, and mostly is the working-yard preparation, is subjected to the working-yard condition influence bigger, mortar strength differs, the quality instability.And the unit dry weight of light-weight insulating brick is generally 400~900kg/m 3, thermal conductivity is 0.08~0.25W/mK, intensity is comparatively balanced, because unit dry weight, thermal conductivity differ bigger between the two, strength matching is unreasonable, causes body of wall to occur following subject matter easily: and the one, the body of wall heat bridge is comparatively obvious, and heat-insulating property is poor; The 2nd, easy to crack, the infiltration of body of wall.Have a strong impact on construction quality and work-ing life, also restricted applying of novel wall material.
Relevant both at home and abroad by retrieval scientific and technical literature is found: the Henan building materials first phase in 2003 was published " development of gas concrete heat-insulating masonry mortar ", introduced the masonry mortar that utilizes waste plastic foam, cement, river sand and the preparation of 107 glue, but mortar volumetric shrinkage in construction process of waste plastic foam preparation is bigger, easily causes the hollowing cracking; The New Building Materials third phase in 2000 was published " development of air-entrained concrete building block building heat insulation mortar ", introduced the mortar applicable cases of utilizing cement, perlite and admixture to produce, but perlite water regain Da Yi efflorescence easily causes the mortar later strength low; Building material technique had been published " novel development of building by laying bricks or stones with thermal insulation mortar " with the application fourth phase in 2006, fiber, sand grating and air entrapment agent have been discussed to being the influence of the mortar of aglite with the haydite, its mortar thermal conductivity is 0.4~0.6W/ (m.k), but the haydite rough porous, workability is poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of inorganic heat-insulating mortar for light insulating brick masonry and preparation method thereof; this mortar is a gelling material with cement, flyash; with the glass bead is light skeletal; have characteristics such as thermal conductivity is low, shrinkage value is low, intensity is high, workability is good; problems such as existing body of wall heat bridge, heat-insulating property are poor, body of wall infiltration easy to crack, work-ing life are short have been solved when using existing common masonry mortar to build light-weight insulating brick by laying bricks or stones effectively.
Technical scheme of the present invention: its feed composition and weight content are: 10~30 parts in flyash, 15~35 parts of glass beads, 1~8 part of wilkinite, 10 parts of dry hydrates, 250~400 parts in sand, 100 parts of cement.
Above-mentioned flyash is I level or II level flyash; Above-mentioned glass bead is that unit weight is less than 120/m 3II class expanded and vitrified small ball; Above-mentioned wilkinite is the modification sodium bentonite; Above-mentioned sand is through scouring, exsiccant natural sand or quartz sand; Above-mentioned cement is that strength grade is 42.5 ordinary Portland cement or slag cement; Its preparation method is that it is even at first flyash, sand, wilkinite, dry hydrate, cement to be passed through mechanically mixing by aforementioned weight ratio respectively, subsequently glass bead is added by aforementioned weight ratio, even by mechanically mixing once more; Quota is packed again.Above-mentioned inorganic heat-insulating mortar for light insulating brick masonry is to be pre-mixed evenly, the dry powder of quota packing.
Main performance index sees the following form:
Project Measure unit Index
Dry density kg/m 3 <1200
Delamination degree mm <20
Time of coagulation h 3~5h when penetration resistance reaches 0.5MPa
Thermal conductivity W/(m.k) <0.2
Ultimate compression strength MPa ≥5
Bonding strength MPa ≥0.2
Frost resistance 25 times Mass loss≤5, loss of strength≤5
Shrinkage mm/m ≤1.1
The present invention compared with prior art has following beneficial effect: the present invention has following advantage: one, the intensity height, thermal conductivity is low, workability good, good manufacturability; Two, since light-weight insulating brick build employing the present invention by laying bricks or stones, therefore do not have cold and hot bridge and produce, heat insulating effect is outstanding, has avoided because of using the body of wall of common masonry mortar, problems such as existing cold and hot bridge, heat-insulating property difference; Three, avoid producing quality problems such as cracking infiltration because of various material stresses are different because of using the body of wall of common masonry mortar; Four, the present invention adopts the production and the management of batch production, thereby has steady quality, cost is low, material use efficiency is high, constructing operation is simple, avoid mixing at the construction field (site) advantages such as causing environmental pollution.
