When the phase-change energy-storing gypsum board is adopted as an inner wall, the indoor temperature fluctuation of a house can be controlled to be between 2 and 4 DEG C, thereby the gypsum board has good temperature control effect.
Description
Technical field
The utility model belongs to building material technical field, specifically is a kind of phase-change energy-saving paper-surface plasterboard.
Background technology
The research of phase-change material can be traced back to after the World War II the earliest for the application of storing solar energy.Nineteen sixty-five the U.S. Mavleous and the Desy clothes that utilizes phase-change material to make to have the heating back pad.Along with the man space technology rapid development, U.S. NASA has greatly developed phase-change material thermal control technology, and Apollo 15 is used for signal processing unit with the phase-change material system, drives control electronic device and lunar communication TU Trunk Unit.
The seventies in last century, Mitsubishi electronics corporation and company of Tokyo Electric Power unite the phase-change material research of having carried out being used for heating and refrigeration.Research and the application work of having carried out planned phase-change energy-storage composite material is presided over by solar energy department of USDOE.The eighties, along with the understanding of people to energy crisis, the research of phase-change material reached the peak period so far.The subordinate's of International Energy Agency in 1998 ECES working group starts the Annex10 plan that themes as " phase transformation and chemical reaction energy storage "; Calendar year 2001 has started the Annex17 plan again on the basis of Annex10 plan, advanced person's the phase change energy storage technology and the research promotion of material are arrived different field.Phase-change material in the modern agriculture greenhouse, refrigeration and transportation, physics medical treatment (thermotherapy), electronic equipment dissipating heat, sportsman's cooling (warming) dress ornament, special temperature-controlled garment, Space Science and Technology, military infrared camouflage, the power peak regulation of solar energy utilization, biological medical product and food use, industrial exhaust heat stores utilization etc., and numerous areas all have application prospect.
The research that phase-change material is used for gypsum plank still is in the imperfection stage.Kedl etc. are used for passive solar energy utilization with octadecane dipping gypsum plank, and result of study shows that the gypsum plank that dipping obtains has higher energy storage density than the wallboard that directly mixes the octadecane particle.Shapiro etc. attempt to find out at the climatic characteristic of Florida and are fit to introduce the phase-change material of gypsum plank as ergastic substances, and these materials comprise the mixture of methyl ester, methyl hexadecanoate, and short chain acids and capric acid, laurate mixture.Although they have high relatively heat storage capacity, phase transition temperature is not included in the livable temperature range in hot climate area fully.The butyl stearate that Feldman directly mixes 21-22% in the agitation phases of conventional gypsum plate production makes energy-storage gypsum plate.The physical-mechanical property of the gypsum plank of adding butyl stearate is suitable with the respective value of ordinary gypsum board, and heat storage capacity has increased by 10 times.
The utility model content
The technical problems to be solved in the utility model provides a kind of phase-change energy-saving paper-surface plasterboard with fine temperature control effect.
In order to address the above problem, the utility model provides a kind of phase-change energy-saving paper-surface plasterboard to comprise: gypsum plank matrix and microencapsulated phase change material particle, described microencapsulated phase change material uniform particles is dispersed in the described gypsum plank matrix, and described plaster matrix upper and lower surface also is respectively arranged with one deck mask paper.
Preferably, described microencapsulated phase change material particle comprises clad and variant mutually, and described phase variant is coated in the described clad.
Preferably, described clad is a polyureas, and described phase variant is an industrial paraffin.
The utlity model has following advantage:
1, the phase-changing energy-storing gypsum plank that the utility model proposes is the product of consumption maximum in the building materials of gypsum product a---Thistle board, therefore need to consider the influence of wall material to boning between gypsum board core and mask paper of microencapsulated phase change material, therefore, the utility model is based on the Thistle board technology of routine, and in the technology for producing paper-face plaster board of routine, increase the pre-dispersed step of microencapsulated phase change material particle, not only make the industrialization of this utility model be easy to realize, reduce preparation technology's cost, and overcome the particle agglomeration of generation when the microencapsulated phase change material particle directly mixes and the phenomenon of skewness.Therefore, phase-change energy-saving paper-surface plasterboard that the utility model proposes and preparation method thereof has embodied environmental protection and energy-conservation characteristics more;
The fluctuation of the house interior temperature that 2, to adopt phase-changing energy-storing gypsum plank of the present utility model be interior wall can be controlled at 2～4 ℃, therefore has good temperature control effect.
