Embodiment
Provide preferred embodiment of the present invention below, to describe technical scheme of the present invention in detail.
Thermal insulation mortar of the present invention comprises following component, by proportioning per ton: 600KG (kilogram) silicate cement, the silicon powder of 80KG, the polypropylene fibre of the flyash of 50KG, 5KG, wood fibre 15KG, 5KG, the conductive powder of 50KG, the Vltra tears of the polymerization rubber powder of 15KG, 10KG, the hollow glass bead of 170KG.
Thermal insulation mortar is a kind of novel heat insulation lagging material and is kervit microbead insulated sand slurry, its lagging material is selected inorganic hollow glass bead, can make the thermal insulation separation thermosphere of every square metre be formed by a tens thousand of individual or several hundred million heat insulation glass bead of miniature hollow insulation, cold and hot air is isolated effective, and heat insulating efficiency is high; It is high that ultimate compression strength and pressure are cut cohesive strength, Wind-Pressure Resistance, and weather resisteant is good, and dry shrinkability is few, and construction is without grid cloth; Fire line spy is good, can not burn, and belongs to the fire prevention of A level; Have anti-aging, ant prevention is bitten and is stung, without features such as obnoxious flavour volatilizations; The stability of thermal insulation layer and permanence are all fine, construct also very easy, and construction costs is lower.
Because glass bead is closed pore, as will increase its proportion after breaking, reduce its heat-insulating property.So the feeding sequence in production process must carry out according to the frangible material character of glass bead: the silicate cement after metering, silicon powder, flyash, polypropylene fibre, water-resisting agent, wood fibre, conductive powder, polymerization rubber powder, Vltra tears first drop in stirring host and carry out just stirring; stir after 2～3 minutes and drop into again the hollow glass bead measuring, continue to stir after 1～2 minute and can discharging pack.
Glass bead is a kind of acid glassiness lava mineral substance (perlite ore) type environment-friendly novel inorganic light weight thermal insulation material, through special technique processing and production technique, is processed to form inner porous, surperficial vitreous sealing; be spherule footpath particle, except thering is light weight, insulation; adiabatic; outside fp excellent properties, also have and do not burn, intensity is high; water-intake rate is low; easily and property good, the advantages such as long service life, are a kind of high performance novel inorganic light heat-insulating materials that has.Its main chemical compositions is: Si02, AI203, CaO, and glass is 0.1-2mm through microballon particle diameter, unit weight 50-100KG/M3; thermal conductivity 0.028-0.048W/M.K, its floatability is greater than 95%, and balling-up vitreous rate is greater than 95%; water-intake rate is less than 50%, and dissolving temperature is 1200 degrees Celsius.Painting on silk position is irregular spherical particle, and inside is porous air cavity configuration, surperficial vitreous sealing, and gloss is level and smooth, and physicochemical property is very stable.Because of its numerous good characteristics, alternative fly ash float, glass microballon, pearlstone, the application of many traditional lightweight aggregates such as granular polystyrene in different goods, is widely used in industry, agricultural, building materials, chemical industry, smelts many fields such as light industry.
During due to surperficial vitreous, formed certain granule strength, so vitreous pearl physicochemical property is very stable, ageing-resistant weathering resistance is strong, has excellent thermal insulation; fire prevention, sound absorption qualities, so in a lot of fields as light filler and thermal insulation; fire prevention, sound-absorbing, lagging material.In building material industry, with glass bead as aglite, can improve mortar with easy mobility and certainly anti-intensity, reduce material contracts rate, improve product over-all properties, reduce comprehensive production cost.At lightweight dry-mixed mortar (thermal-insulating type, build type by laying bricks or stones, the type of wiping one's face) in application, with glass bead, substitute traditional normal expanded perlite and granular polystyrene and be dry mixed thermal insulation mortar aglite, overcome pearlstone water-absorbent large, easily efflorescence, in slip stirs, volumetric shrinkage is large, easily cause the phenomenons such as the low and hollowing cracking of product later strength, made up granular polystyrene organic materials inflammable simultaneously, fire resistance is poor, high temperature generation obnoxious flavour and ageing-resistant weathering resistance are low, the defect such as in construction bounce-back property is large, improved over-all properties and the workability of thermal insulation mortar perfect.
Adopting glass bead is single group thermal-insulating type dry-mixed mortar of light thermal insulation aggregate; by a large amount of engineering application, confirm that it not only meets the relevant building energy-saving standard of country on wall thermal insulating requires; and single-component thermal-insulating type dry-mixed mortar guaranteed the stability of quality product, quality unstable when having overcome two components or many components thermal insulation mortar and coordinating at the scene.
Secondly, the cohesive strength of glass bead is high, and early strength improves fast, is obviously better than take the thermal insulation mortar that granular polystyrene and common perlite are aglite, has shortened the time that secondary is plastered, and has improved operating efficiency.
Again, glass has good water-retentivity and splitting resistance through microballon, on the body of wall of various base materials, do not need to water or interface processing, and direct dry smearing in metope, hollowing, does not ftracture, and has greatly improved operating efficiency and over-all properties, has reduced engineering cost.Particularly in Xia Redong cold-peace hot summer and warm winter region, use, will produce fabulous Social benefit and economic benefit.
In a word, thermal-insulating type dry-mixed mortar has great market area and development prospect in China's building energy saving field.In refractories industry, utilize glass bead to substitute fly ash float, produce light-weight refractory insulating brick and special-shaped casting material; in chemical industry; utilize glass bead as closely knit conditioning agent, at smelting industry, substitute the aspects such as pearlife, all obtained good society and economic benefit.
Kervit microbead insulated sand slurry be by glass through microballon, binding agent (cement, gypsum etc.) and multiple additives are optimized proportioning in factory, the dry powder bulk cargo evenly mixing through Special agitating preparation.Kervit microbead insulated sand slurry is a kind of inorganic heat-insulating material; there is excellent insulation, heat-proof quality and fire prevention, ageing-resistant performance; can be widely used in new and old building thing wall thermal insulating engineering; can effectively improve indoor thermal environment, spread upon on exterior wall intensity high, hollowing cracking; and be highly susceptible to operation; site operation adds water and stirs and can use, and can directly construct on dry shape body of wall, has good workability.In performance, overcome pearlstone light skeletal water-absorbent large, easily efflorescence, in construction, volumetric shrinkage is large, easily causes the low and hollowing cracking of product later strength, reduces the phenomenons such as heat-insulating property.The defects such as simultaneously made up again granular polystyrene organic materials inflammable, fire line is poor, and high temperature produces obnoxious flavour and ageing-resistant, and weathering resistance is low and workability is poor, and in construction bounce-back property is large, have improved over-all properties and the workability of insulating dry powder mortar greatly.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
