Abstract

The invention relates to a glazed hollow bead thermal insulation mortar and a preparation process thereof, which are applicable to interior and exterior thermal insulation plastering projects of enclosure walls of multi-storey and high-rise buildings and the like, as well as fire prevention and thermal insulation projects and thermal insulation transformation projects of old buildings. The glazed hollow bead thermal insulation mortar is prepared by the raw materials of ordinary Portland cement, ash calcium powder, sand, lignin, polypropylene staple fiber, silica fume and composite resin rubber powder in parts by weight, and can overcome great hydroscopicity and easy pulverization of expanded perlite, large volume shrinkage during stirring of slurry, and easy emergence of the phenomena of low strength, hollowing, cracking and the like during the late stage of a product, simultaneously make up for defects of flammability of polyphenyl granular organic material, poor fireproof performance, production of harmful gas due to high temperature, low aging resistance and weather resistance, large rebound resilience during construction and the like, and enhance and improve comprehensive performance and construction performance of the thermal insulation mortar.

Description

Kervit microbead insulated sand slurry and preparation technology thereof
Technical field
The present invention relates to a kind of thermal insulation mortar; relate in particular to a kind of kervit microbead insulated sand slurry and preparation technology thereof; be applicable to the inside and outside insulation plastering engineering of the enclosure walls such as Steel Concrete, gas concrete, building block, vitrified brick, no-firing brick and light wall material of multilayer and Highrise buildings; and fireproof heat insulating engineering such as vault, garage, stair, corridor, fire passage, and be specially adapted to the heat insulating improvement project of old building.
Background technology
Thermal insulation mortar is meant and is used for carrying out a kind of material of construction that thermal insulation layer construction is adopted constructing the surface.The thermal insulation layer construction generally is divided into three layers, and the first layer is to smear one deck bonding mortar on the body of wall of levelling, is made up of materials such as fine sand, cement, admixtures, and major function is to play ligation between body of wall and thermal insulation layer; The second layer is a thermal insulation layer, with granular polystyrene sheet forming or extruded sheet, or with the mixed mortar that is mixed with light materials such as granular polystyrene, perlite, glass bead; The 3rd layer is crack-resistant layer, promptly smears anticracking grout outside thermal insulation layer, is made up of cement, fiber, sand and admixture etc., as requested, metal or glass fiber net grid material is set in crack-resistant layer sometimes in the construction.Thereby thermal insulation mortar comprise bonding mortar, with light material blended thermal insulation mortar and anticracking grout.
Glass bead is a kind of acid glassiness lava mineral substance (pitchstone ore in sand form); be processed to form inner porous, surperficial vitreous sealing through special technology processing and production technique; being the thin footpath of spherule particle, is a kind of high performance novel inorganic light heat-insulating material that has.Because surperficial vitreous forms certain granule strength, physicochemical property is very stable, and ageing-resistant weathering resistance is strong, has excellent thermal insulation, fire prevention, sound absorption qualities, is fit to do in the numerous areas lightweight filler aggregate and thermal insulation, fire prevention, sound-absorbing, lagging material.In building material industry, as aglite, can improve the easy mobility of mortar and anti-certainly intensity with glass bead, reduce the wood property shrinking percentage, improve the product over-all properties, reduce comprehensive production cost.
Thermal insulation mortar of the prior art mostly exists big, the easily efflorescence of water-absorbent, volumetric shrinkage is big in slip stirs, easily cause phenomenons such as the low and hollowing cracking of product later strength, that the thermal insulation mortar that has simultaneously also exists is inflammable, fire resistance is poor, high temperature produces obnoxious flavour and ageing-resistant, weathering resistance is low, defectives such as bounce-back property is big in the construction.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art; a kind of kervit microbead insulated sand slurry is provided; solve in the prior art thermal insulation mortar and mostly existed big, the easily efflorescence of water-absorbent; volumetric shrinkage is big in slip stirs; easily cause the problem of phenomenons such as the low and hollowing cracking of product later strength, and the present invention has overcome thermal insulation mortar is inflammable, fire resistance is poor, high temperature produces obnoxious flavour and ageing-resistant, weathering resistance is low, defectives such as bounce-back property is big in the construction.
Another object of the present invention is to provide a kind of preparation technology of kervit microbead insulated sand slurry.
Technical scheme of the present invention is as follows:
Count ratio by following raw materials in parts by weight and be prepared from ordinary portland cement: grey calcium powder: sand: xylogen: polypropene staple: silicon ash: compound resin rubber powder=300-420: 80-120: 550-700: 3-8: 1-2: 30-60: 22-38.
Described ordinary portland cement is the 42.5R ordinary portland cement.
Described grey calcium powder is 400 orders.
Described sand is the 40-70 order.
Preparation technology comprises the steps:
Sieve apparatus is arranged in stirring tower bottom, the sand that sieves the back different stage is promoted to top of tower, send into each sand storehouse;
Xylogen that volume is little and polypropene staple be through platform balance separately after the metering, with above-mentioned other compound through a small-sized mixing machine premix, enter big mixing machine behind the premix, mixing time is 120~180 seconds;
The mortar of above-mentioned mixing and stirring adopts packed packaged, gets finished product.
Advantage of the present invention and beneficial effect are as follows:
In thermal insulation mortar is used; substitute traditional normal expanded perlite and the dried thermal insulation mortar aglite that mixes of granular polystyrene work with glass bead; overcome big, the easily efflorescence of pearlstone water-absorbent; volumetric shrinkage is big in slip stirs; easily cause phenomenons such as the low and hollowing cracking of product later strength; remedied again simultaneously that the granular polystyrene organic materials is inflammable, fire resistance is poor, high temperature produces obnoxious flavour and ageing-resistant weathering resistance is low, defectives such as bounce-back property is big in the construction, improved the over-all properties and the workability of thermal insulation mortar perfect.
Performance index are as follows:
1, dry density (kg/m3) 260
2, slurry density (kg/m3) 680
3, thermal conductivity [w/ (m.k)] 0.06
4, ultimate compression strength (kPa) 350
5, cohesive strength (kPa) 120
6, tensile strength (kPa) 180
