Description
Technical field
The present invention relates to a kind of building heat preservation lagging material, a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar is specifically provided.
Background technology
Existing thermal insulation mortar generally contains cement, light skeletal, fiber and other sorbing materials, exist water-intake rate large, water-repellancy is poor, and coefficient of softening is low. and not water-fast. the defects such as thermal conductivity height, and during construction, be subject to weather effect larger, be unfavorable on time normally carrying out of construction.
Summary of the invention
The present invention be directed to above problem, provide a kind of use safety, easy construction, intensity is suitable, and the Macromoleclar polymer thermoregulation energy-storage insulation mortar that cost is low, by the sun power of pollution-free cheapness, wind energy, heat energy directly stores the supplemental heat source as lagging material, reaches save energy object.
The technical solution adopted for the present invention to solve the technical problems is:
A Macromoleclar polymer thermoregulation energy-storage insulation mortar, its formula comprises the mineral fibre that accounts for gross weight 0-10%, the sorbing material of 5%-20%, the agglutinate of 5%-30% and 20%-50% stopping composition, its formula also comprises the phase change material that accounts for gross weight 5%-30%.
Phase change material in a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is calcium chloride, and chemical formula is CaCl6HO
2, calcium chloride is as moisture absorption phase change material, and low price also has the character such as zero pour is low, water absorbability strong, easy deliquescence, low temperature phase change, has obtained a large amount of application in industry.Calcium chloride can accelerate mortar sclerosis, shorten set time and increase the tolerance to cold of mortar.In conjunction with buildings natural climate condition of living in, making full use of the hygroscopic nature of calcium chloride and phase-change characteristic manufactures some material of construction and is applied to architectural exterior-protecting construction, can realize the conversion of outdoor solar radiation and control, reduction indoor air temperature and humidity, improve indoor thermal environment of building, reach the utilization of save energy, the renewable energy resources and realize the object of Sustainable development.
The mineral fibre of a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is brucite, brucite fiber is harmless to people, light weight easily disperses, one-tenth amount slurry is large, after slurry is dry, form microporous network structure, have good thermal and insulating performance and weather resistance, the large raw material abundance of storage capacity is the ideal material that replaces fibrous magnesium silicate at home.
The sorbent material of a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is attapulgite, attapulgite is to utilize natural nonmetalliferous ore-attapulgite clay (Attapulgiteclay) through scientific formula and a kind of product of being processed into by special process, be the product that collects anti-salt, adsorbs, is bonded in one, can be used as lagging material binding agent, main absorption, bonding calcium chloride.
The stopping composition of a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is pearlstone, and unit weight is less than 150 kilograms, and granularity is 0.01-3mm.Due to advantages such as pearlstone has light weight, thermal conductivity is little, heat insulating ability is strong, water absorbing properties strong, low prices, therefore select pearlstone as the matrix of moisture absorption porous material.Known according to the analysis discussion to hygroscopic nature, matrix hygroscopic property is strong, and material surface is difficult for gathering solution, can strengthen matter exchange capacity, is also conducive to the thermal insulation separation heat energy of architectural exterior-protecting construction due to the low heat conductivity of pearlstone self simultaneously
The agglutinate of a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention can be inorganic binder, as cement, lime, water glass, high molecular polymer rubber powder etc.For improving bonding strength and the weather resistance of building foundation material, generally so that inorganic binder is a kind of, be used in conjunction with organic binder.
When a kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is used, the above-mentioned materials of take mixes as 1: 1.5 with water ratio, can carry out plastering construction at walls and roofs.
A kind of Macromoleclar polymer thermoregulation energy-storage insulation mortar in the present invention is owing to having adopted the moisture adsorption and releasing phase change material of multiple stay in grade, wide material sources, cheapness, to hot-fluid, conduction has very high impedance, can fully absorb and lay in sun power and heat energy again, transformation temperature is adjustable at 5-55 degree, therefore be widely used in the alternative glue powder polyphenyl particle of all kinds of Energy Conservation Project in Constructions, other slurry class thermal insulation mortar and styrofoam, can directly at brick wall, concrete walls, top ceiling etc., construct, the not nontoxic easy construction of area occupied, the superiority such as cheap.
Macromoleclar polymer thermoregulation energy-storage insulation mortar of the present invention, it adds calcium chloride in existing batching, has improved the workability of thermal insulation mortar, water resistance, water resistance and coefficient of softening, the water-absorbent of thermal insulation mortar is also well controlled.
When envrionment temperature raises, calcium chloride moisture releasing, can significantly not raise because of the rising of envrionment temperature the temperature of institute's object of protection.Calcium chloride moisture absorption when envrionment temperature reduces, can obviously not reduce because of the reduction of envrionment temperature the temperature of institute's object of protection.That is to say the heat storage capacity that has improved thermal insulation mortar by the moisture adsorption and releasing of calcium chloride, thereby make thermal insulation mortar there is good heat-proof quality.
The heat-insulating property of Macromoleclar polymer thermoregulation energy-storage insulation mortar of the present invention is mainly by adding the light skeletal that thermal conductivity is low to realize, the brucite fiber simultaneously adding and protruding excellent powder light weight calcium material, not only play the effect of the bonding calcium chloride of absorption, heat-insulating property is also had to certain contribution.
The present invention solves that existed building thermal insulation mortar water-intake rate is large, and water-repellancy is poor, and coefficient of softening is low, not water-fast, thermal conductivity high-technology problem.The various thermal insulation layers that can be used for body of wall and roofing.Contained calcium chloride undergoes phase transition to transform and exists moisture absorption and moisture releasing process under 18C ℃-50C ℃ condition, can play fine accumulation of heat effect, thereby changes indoor thermal environment.
Macromoleclar polymer thermoregulation energy-storage insulation mortar of the present invention has heat insulating double effects, insulation effect realizes by the lower light skeletal of thermal conductivity adding, and moisture absorption and moisture releasing transformation that heat-blocking action mainly passes through added calcium chloride realize.
