Abstract

The invention discloses an inorganic wall heat insulation mortar. The inorganic wall heat insulation mortar is prepared through using the following raw materials, by mass, 30-60% of white cement, 20-50% of calcium powder, 12-30% of vitreous bead, 3-20% of asbestos, 1-3% of mica, 0.1-0.6% of HPMC, 1-8% of bentonite, 0.2-0.7% of lignocellulose and 1-4% of gold sand. The insulation mortar has the characteristics of non-combustible A grade, light weight, high strength, good heat insulation performance, heat conduction coefficient being 0.055-0.042w/mk, easily available raw materials, low cost, and no generation of three wastes, and is a preferred material for energy saving and heat insulation.

Description

Inorganic wall heat insulation mortar
Technical field
The invention belongs to building material technical field, be specifically related to a kind of Inorganic wall heat insulation mortar with fireproof heat insulating function.
Background technology
At present, the ortho-water silt particle dress still followed for many years that inside and outside the most architectural exterior-protecting construction of China, metope uses, the thermal conductivity of this conventional cement mortar is very high, the function stoping heat to transmit is very poor, in the area that indoor/outdoor temperature-difference cold in winter and hot in summer is very large, often consume a large amount of energy because of the frequent heat exchange of air.In order to solve the problem, people's prelibation adds the particle of a certain amount of polystyrene or other plastic materials in ortho-water silt particle dress, wish the heat-insulation and heat-preservation requirement being met metope particularly wall face by the thermal resistance characteristic of the particle such as polystyrene or plastics, but the wall surface mortar material of this improvement still also exists waterproof and dampproof poor-performing, heat-insulation and heat-preservation ability, the defects such as the crack that Mortar shrinkage produces.
Summary of the invention
For solving the above-mentioned defect that prior art exists, 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 heat insulation mortar that viscosifying power is strong.
For achieving the above object; the technical solution used in the present invention: this Inorganic wall heat insulation mortar, is characterized in that preparing by following materials in percentage by mass: 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 heat insulation mortar, prepares 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%.
Said ratio raw material adds water and stirs and can use.
In proportioning of the present invention, white cement, calcium powder are as major ingredient, fully can be combined with light skeletal, and firmly can be bonded together with body of wall, form firm thermofin at wall.Glass bead is a kind of acidic glass matter lava mineral substance (pitchstone ore in sand form); close through Duo Kong ﹑ surface vitreous in portion Nei special technology process and production technique are processed to form; the thin footpath particle in spherule; physicochemical property is stable, combustionproperty is A level, is that one has high performance novel inorganic light heat-insulating material.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 DEG C.Glass bead compensate for makes many defects and deficiency in other Conventional insulation of aglite with granular polystyrene and normal expanded perlite; the glass bead of hollow overcomes that pearlstone water-absorbent is large, easily efflorescence, in stirring, volume receives that mistake rate is large, product later stage heat-insulating property reduces and the easy weak point such as hollowing cracking, the defect such as simultaneously compensate for again that granular polystyrene organic materials is inflammable, fire resistance is poor, intensity low and high temperature produces obnoxious flavour and ageing resistance weathering resistance is low.Asbestos have extremely fireproof, electrical insulating property and heat insulating ability, are important fire prevention, insulation and lagging material.The characteristic of mica is insulation, high temperature resistant, glossy, physical and chemical performance is stablized, and has good thermal insulation, elasticity and toughness.Wilkinite has very strong water absorbability, can adsorb the water that is equivalent to own vol 8 one 20 times and be expanded to 30 times; Can disperse in water medium in soliquid, and have certain viscosity, thixotropy and oilness, it has plasticity-and cohesiveness with the admixture of silt etc., has stronger cation exchange capacity (CEC) and adsorptive power.Lignocellulose (Methyl Cellulose) is that natural reproducible timber processes through chemical treatment, mechanical process the organic wadding fibrous material obtained, nontoxic, tasteless, pollution-free, "dead".Good effect is had to preventing coating cracking, raising water-retentivity, the stability improving production and the conformance of construction, the sticking power etc. of effects on surface of gaining in strength, strengthen.The husky intensity adding whole mortar as filler of gold.HPMC is: Vltra tears, English name: Hydroxy Propyl Methyl Cellulose, there is thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, excellent film-forming properties and the feature such as resistance to enzymatic, dispersiveness and cohesiveness widely.The dispersiveness of cement-sand can be improved, significantly improve plasticity-and the water-retentivity of mortar, effective to preventing crackle, can refinforced cement intensity.
The present invention fills a prescription, and fire prevention does not fire A level, high-strength light, water resistant, and 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, produces without the three wastes, is the preferred material of energy-saving heat-insulating insulation.
