Description

The inorganic wall insulating mortar

Technical field

The invention belongs to building material technical field, be specifically related to a kind of inorganic wall insulating mortar with fireproof heat insulating function.

Background technology

At present, the ortho-water silt particle still followed for many years that in the most architectural exterior-protecting constructions of China, wall face is used fills, the thermal conductivity of this conventional cement mortar is very high, the function that stops heat to transmit is very poor, the very large area at indoor/outdoor temperature-difference cold in winter and hot in summer, often the frequent heat exchange because of cold and hot air consumes a large amount of energy.In order to address the above problem, people's prelibation adds the particle of a certain amount of polystyrene or other plastic materials in ortho-water silt particle dress, hope meets the particularly heat-insulation and heat-preservation requirement of wall face of metope by the thermal resistance characteristic of the particles such as polystyrene or plastics, but this improved wall surface mortar material still exists waterproof and dampproof poor-performing, the heat-insulation and heat-preservation ability, the defects such as crack that Mortar shrinkage produces.

Summary of the invention

The above-mentioned defect existed for solving prior art, the object of the present invention is to provide a kind of thermal and insulating performance good, fire prevention, water resistant, high-strength light, the inorganic wall insulating mortar that viscosifying power is strong.

For achieving the above object; the technical solution used in the present invention: this inorganic wall insulating mortar is characterized in that by following materials in percentage by mass preparation: white cement 30-60%, calcium powder 20-50%, glass bead 12-30%, asbestos 3-20%, mica 1-3%, HPMC 0.1-0.6%, wilkinite 1-8%, lignocellulose 0.2-0.7%, the husky 1-4% of gold.

Preferential, this inorganic wall insulating mortar, prepare by following materials in percentage by mass: white cement 40%, calcium powder 30%, glass bead 20%, asbestos 5%, mica 1%, HPMC 0.5%, wilkinite 1%, lignocellulose 0.5%, gold sand 2%.

The said ratio raw material adds water and stirs and can use.

In proportioning of the present invention, white cement, calcium powder be as major ingredient, can with the abundant combination of light skeletal, and can firmly be bonded together with body of wall, form firm thermofin at wall.Glass bead is a kind of acid glassiness lava mineral substance (pitchstone ore in sand form); be processed to form the vitreous sealing of the Duo Kong ﹑ of Nei section surface through special technology processing and production technique; be the thin footpath of spherule particle; physicochemical property is stable, combustionproperty is the A level, is a kind of high performance novel inorganic light heat-insulating material that has.Main chemical is Si02 ﹑ AI203 ﹑ CaO, and grain diameter is 0.1-2mm, and unit weight is 50-100kg/m3; thermal conductivity is 0.028-0.048W/m ﹒ K, and its floatability is greater than 95%, and balling-up vitreous rate is greater than 95%; water-intake rate is less than 50%, and melt temperature is 1200 ℃.Glass bead has made up with granular polystyrene and normal expanded perlite and has made many defects and deficiency in other traditional lagging materials of aglite; the glass bead of hollow overcomes that the pearlstone water-absorbent is large, easily efflorescence, in stirring, volume receives that the mistake rate is large, product later stage heat-insulating property reduces and the easy weak point such as hollowing cracking, the defect such as made up again that the granular polystyrene organic materials is inflammable, fire resistance is poor, the intensity low and high temperature produces obnoxious flavour simultaneously and the ageing resistance weathering resistance is low.Asbestos have extremely fireproof, electrical insulating property and heat insulating ability, are important fire prevention, insulation and lagging materials.The characteristic of mica is insulation, high temperature resistant, glossy, physical and chemical performance stable, has good thermal insulation, elasticity and toughness.Wilkinite has very strong water absorbability, can adsorb the water that is equivalent to 8 one 20 times of own vols and be expanded to 30 times; Can disperse to be soliquid in water medium, and have certain viscosity, thixotropy and oilness, the admixture of it and silt etc. has plasticity-and cohesiveness, and stronger cation exchange capacity (CEC) and adsorptive power are arranged.Lignocellulose (Methyl Cellulose) is the organic wadding fibrous material that natural reproducible timber obtains through chemical treatment, mechanical process processing, nontoxic, tasteless, pollution-free, "dead".The conformance that prevents coating cracking, raising water-retentivity, the stability that improves production and construction, the sticking power of gaining in strength, strengthen effects on surface etc. are had to good effect.Gold sand has increased the intensity of whole mortar as filler.HPMC is: Vltra tears, English name: Hydroxy Propyl Methyl Cellulose, there is thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, good film-forming properties and characteristics such as anti-enzyme, dispersiveness and cohesiveness widely.Can improve the dispersiveness of cement-sand, significantly improve plasticity-and the water-retentivity of mortar, produce effect to preventing crackle, but refinforced cement intensity.

The present invention's formula, the A level is not fired in fire prevention, high-strength light, water resistant, thermal and insulating performance is good, and thermal conductivity can reach 0.055-0.042w/mk, and materials cost is easy to get, with low cost, without the three wastes, produces, and is the preferred material of energy-saving heat-insulating insulation.
