Description
Technical field
The present invention relates to technical field of phase-change energy storage, in particular to a kind of Phasochange energy storage ceramic particle and its preparation
Method.
Background technology
With the rapid development of social economy, energy problem is increasingly becoming the key factor for restricting social development.It is for building
The 20-40% that primary energy consumption can be accounted for is even as high as 45% in certain developed regions.Expect the year two thousand twenty, national highly energy-consuming
Construction area is up to 70,000,000,000 square metres.So if not focusing on energy-saving design in construction, it will directly aggravate energy crisis.Phase transformation
Energy storage is a kind of contradictory energy storage technology between effectively solving the new energy supply and demand such as solar energy, wind energy, is to improve using energy source effect
Rate, energy saving effective means.Phase-change material as a kind of efficient ergastic substances, can both have been promoted construction material function,
Building energy consumption and adjustment Building Indoor Environment comfort level are reduced, and available thermal energy can be carried out in the form of latent heat of phase change
Storage, to realize the storage and conversion that can utilize thermal energy.
Since solid-liquid phase change material has thermal coefficient small, melts easily leakage, volatile, easy firing and perishable lack
Point.In engineer application, solid-liquid phase change material will have a kind of carrier to accommodate or encapsulate package, bring it about the variation of solid-liquid " phase " state
When, liquid is not leaked or is oozed out, otherwise has its volume expansion of space or contraction, is kept material indeformable or is ruptured.Therefore real
It is substantially the figuration composite phase-changing material of a kind of coated or support type with property phase-changing energy storage material, can not only material is made to exist
It keeps macroshape not change when phase transformation, also solves leakage problems.In the prior art, patent CN 102888211A are public
Opened it is a kind of with polyaniline and long chain fatty acids surfactant, the initiator the effects that under shaping phase-change material obtained, but
Preparation process is complicated, and the raw material for being used to prepare backing material polyaniline is more toxic, and is carcinogen.Patent CN
103666380A discloses a kind of preparation method of porous media composite phase change energy-storing particle, using porous minerals as load
Body carries out mixing and absorption to liquid state phase change material, and is poured into fluid bed, utilizes the cold air pair of certain flow rate in fluid bed
Uncooled phase change grains carry out forced convertion cooling, and so that particle is disperseed using the percussion between air-flow and material.Specially
Sharp CN 103570311A disclose a kind of preparation method of paraffin/expanded perlite phase transition insulation mortar, are made using " two-step method "
For paraffin/expanded perlite phase transition insulation mortar.
However, above several figuration composite phase-changing materials have the following disadvantages：1, phase transition temperature is improper, cannot

Durability is poor, is more easily damaged.3, microcapsules or macromolecule preparation process are complicated, manufacturing cost is high or raw material has poison
Property, and the figuration composite phase-changing material of gained is inflammable.The phase-change material or composite phase-change material prepared using the above technology is existed
Application adaptability in construction material is poor.
On the other hand, diatom plate is a kind of novel environment friendly building materials emerging in recent years, diatom plate in later stage polishing process,
A large amount of dust clout is often will produce, utilization can be recovered by bag collection.Diatom plate polishing process is usually from diatom plate
Surface removes 1mm or so superficial layer, then producing 1m2Diatom plate will form the powder of 1kg or so.It is every in China at present
Year generates millions of polishing dusts.However, the processing of diatom plate polished waste material is relatively low with producing level, stockyard is mostly used greatly or is filled out
The method disposition buried, easily causes local water and air and is contaminated.
In recent years, haydite has abundant pore structure and larger specific surface area and pore volume, is widely used at water
The fields such as reason, household and flame-proof thermal insulation material.Fixed phase change is prepared using the larger haydite of pore structure prosperity and specific surface area
Material is a kind of new developing direction.Such as patent CN 103509529A disclose a kind of Phasochange energy storage ceramic particle and its preparation side
Method successively adsorbs phase-change material by vacuum suction on porous ceramic grain, and this method utilizes the porous characterization of adsorption of haydite, deposits
The shortcomings of adsorbance is small, phase-change accumulation energy unobvious.Patent CN 104291859A disclose a kind of energy storage baking-free sludge haydite,
The energy storage baking-free sludge haydite by phase-changing energy storage material, porous material exciting agent and mud powder by certain mass ratio into
Row mixing composition, but need to carry out steam curing under certain temperature and maintain 24-48 hours, then carry out maintenance one at room temperature again
The section time, still remain that complex process, energy consumption be higher, production cycle longer problem.Patent CN 104086134A disclose one
The advantages of kind paraffin/haydite phase-change accumulation energy concrete, it has both both common building materials and phase-change material, this method include that vacuum is inhaled
Attached to prepare paraffin/haydite sizing phase-change material and be packaged, casting, -48h, form removal continue to conserve to 28d for 24 hours for maintenance,
Production cycle is long, complex process energy consumption is higher.
In view of this, special propose the present invention.

1 Phasochange energy storage ceramic particle of comparative example is using common haydite materials flyash as primary raw material, 2 phase transformation of comparative example storage
Energy haydite is using expanded perlite as primary raw material, and gained haydite intensity is low, phase transformation enthalpy is less than the present invention.
Each raw material proportioning of comparative example 3 is different from embodiment 1, and the intensity and phase-change accumulation energy performance of haydite cannot obtain preferably
Effect, it is seen then that the proportioning between raw material also has a major impact the intensity and phase-change accumulation energy effect of haydite.
Meanwhile preparation method of the invention be mode free of calcining and steam curing, raw material be not necessarily to pre-treatment, have it is simple for process, at
The advantages that this is low, energy-saving and environmental protection.The embodiment of the present invention is storage with organic phase change material using diatom plate polishing powder as primary raw material
Energy material prepares high-strength light phase transformation storage using high strength gypsum, bentonite, waterglass as cementitious material using mode free of calcining and steam curing
It can haydite.The melting that organic phase change material is compensated for using diatom plate polishing powder microstructure advantage and stronger adsorption capacity is let out
The applied defect of leakage, obtained haydite intensity is high, phase-change accumulation energy effect is good, and it is higher to alleviate conventional sintering complex process, energy consumption,
And obtained haydite intensity is low, the unconspicuous problem of phase-change accumulation energy.
Therefore, the present invention has the advantages that environmental-friendly, simple for process, energy consumption is small and waste utilization rate is higher, widens
The support raw material sources of shaping phase-change material have opened up the new way of diatom plate polishing powder comprehensive utilization；Prepared by this method
Unburned Phasochange energy storage ceramic particle product intensity is higher and temperature adjustment function is preferable.
