Description
Technical field
The present invention relates to composite decorative building material field, more particularly to a kind of composite inorganic hydrous salt phase change material and
The preparation method of inorganic compounding phase change plate.
Background technology
At present, a big chunk of social energy wastage in bulk or weight is used for building field.And wherein 70% is heating and air-conditioning institute
Consumption, with the energy, the anxiety of non-renewable resources, utilization of new energy resources and the demand for improving device efficiency find suitably quilt
Dynamic formula energy saving building material, reaches few purpose with or without equipment.The building and ornament materials widely applied now such as Side fascia,
Lining, floor, furred ceiling, pyrogenicity (cold) equipment such as air-conditioning, floor heating, ground source heat, boiler hot hydrophone etc. are all existed and not sympathized with
The problem of condition.
In architectural exterior-protecting construction, comfort level is essentially from five aspects, temperature, humidity, sound absorption, air quality and the ring of light
Border, wherein luminous environment can be understood as the processing of the ornamental visual sense of beauty and light brought.People utilize heating or air-conditioning
Purpose be to reach temperature controlled effect.And if phase-change material is used for into building enclosure, will play or increase well
Plus this effect.In terms of cold-storage, the cold-storage within the time that electricity price is low, air conditioner load is low is released when electricity price is high, air conditioner load is high
It is cold, whole or local transfer cooling load are gone up from the time with this.Adjusted in terms of accumulation of heat using the heat storage capacity of construction material
Indoor heat fluctuation, the fluctuating range of hot-fluid is weakened, and the time of effect is stepped back.Pass through appropriate design, it is possible to temperature
The undulated control of degree is in relatively comfortable scope.
For example in interior wall, exterior wall and ceiling material territory, timber, stone material etc. because it is non-renewable, prevent fires it is resistance to difference and
The reasons such as radioactivity, are largely substituted for synthetic material, and the synthetic material more often used has gypsum, cement, plasterboard or fiber
Plasterboard, gypsum building materials poor water resistance, especially under moisture conditions easy efflorescence, go mouldy, do not reach preferable requirement.
Portland cement board unit weight is larger, it is impossible to for manufacturing the less slim sheet material of thickness.It is to utilize in wall body structure
When middle, meet condensation and dewfall thermal technology property usually because it is poor to the regulation of humidity, during use and decline, easily get damp, surface layer takes off
Fall.
Still there is the presence of the organic volatiles such as free formaldehyde in common glued board, fiberboard, particieboard, for interior
Decoration has unfavorable healthy factor, and fire-protection rating does not reach A grades.Chloride magnesia cement board can accomplish lightweight, high-strength, thin
Type, but poor toughness, easily return halogen, corrode fastener.
Phase change material combines in the building enclosure sheet material of shaping, just forms a kind of new composite energy storage building material.
Had the following advantages using phase change material as energy storage material:First, phase transformation is substantially carried out at a constant temperature, this characteristic is conducive to
Temperature change is maintained in less scope, body-sensing is made one to more comfortable；Second, phase-change material has very high storage density,
