Compared with prior art, two-component heat accumulation Embedding Material of the invention has the advantages that pair of the invention
Component heat accumulation Embedding Material, performance are as follows: specific heat capacity (J/ (gK)) >=2.0；Enthalpy of phase change (J/g) about 30~180, that is, absorb heat
Value；Phase transition temperature (DEG C) 25~90；Specific gravity (g/cc): 0.8~1.8 surface drying time: 15min~25min；The primary solidification time:
1h~2h；Time >=for 24 hours is fully cured；Shear strength (aluminium/aluminium) >=4MPA；Phase-change material is that graphite adsorbs phase-change accumulation energy powder
Or aeroge adsorbs phase-change accumulation energy powder；
Wherein, graphite absorption phase-change accumulation energy powder has selected vermicular expanded graphite as adsorbent material, vermiform expansion
A kind of loose porous vermiform substance that graphite is obtained by natural flake graphite through intercalation, washing, drying, high temperature puffing, it is swollen
Swollen graphite other than having the excellent performances such as the cold-hot of natural graphite itself, corrosion-resistant, self-lubricating, radiation hardness, electric conductivity,
Also there is the unexistent softness of natural graphite, compression resilience, adsorptivity, ecological environment harmony, biocompatibility, radiation hardness
Property etc. characteristics, due to loose porous, large specific surface area, therefore very strong to the adsorption capacity of phase transformation powder, it is only necessary to using compared with
The vermicular expanded graphite of few parts by weight can complete the absorption to phase-change material, and certainly, vermicular expanded graphite cannot be too
It is few, phase-change material can not be adsorbed completely very little；Vermicular expanded graphite can not be too many, on the one hand increases cost if too many
With reduce product heat enthalpy value, meanwhile, reduce graphite absorption phase-change accumulation energy powder enthalpy of phase change, reduce the heat accumulation of product
Can, therefore, for different powders, it is optimal for capable of having adsorbed the weight ratio of phase transformation powder completely just；
And in order to be further reduced the usage amount of vermicular expanded graphite, in the step 2 of preparation method, use true
The attached technique of suction, is stirred under vacuum conditions, and the phase transformation powder of fusing more easily in depth penetrates into vermicular expanded graphite
Be far longer than conventional dipping or stirring in fluffy deep hole, in deep hole to the suction-operated of phase-change material, phase-change material into
It after entering in deep hole, is also difficult to overflow under the high temperature conditions, there is extraordinary absorption property, in this way, vermiform few as far as possible is swollen
Swollen graphite has adsorbed more phase-change materials, and the enthalpy of phase change of graphite absorption phase-change accumulation energy powder increases 5%-10%, and performance obtains
To being substantially improved, due to reducing the dosage of vermicular expanded graphite, cost is also greatly reduced；
Aeroge absorption phase-change accumulation energy powder has selected aeroge as adsorbent material, and aeroge thermal coefficient is low, heat preservation
Good heat-insulation effect, stable in physicochemical property, high temperature is non-ignitable, completely waterproof, and nonhazardous, environmentally protective, and large specific surface area, to phase
The adsorption capacity for becoming powder is very strong, it is only necessary to can complete the suction to phase-change material using the aeroge of less parts by weight
Attached, certainly, aeroge cannot be very little, can not adsorb phase-change material completely very little；Aeroge can not be too many, it is too many if one
Aspect increases the weight of cost and product, meanwhile, the enthalpy of phase change of aeroge absorption phase-change accumulation energy powder is reduced, product is reduced
Thermal storage performance, therefore, for different phase transformation powders, it is optimal for capable of having adsorbed the weight ratio of phase transformation powder completely just
's；
And in order to be further reduced the usage amount of aeroge, in the step 2 of preparation method, using vacuum suction
Technique stirs under vacuum conditions, and the phase transformation powder of fusing more easily in depth penetrates into the fluffy deep hole of aeroge, deep hole
The interior suction-operated to phase-change material is far longer than conventional dipping or stirring, after phase-change material enters in deep hole, in height
It is also difficult to overflow under the conditions of temperature, there is extraordinary absorption property, in this way, aeroge few as far as possible has adsorbed more phase transformation materials
The density of material, aeroge absorption phase-change accumulation energy powder improves 10-15%, and aeroge adsorbs the enthalpy of phase change of phase-change accumulation energy powder
5-15% or so is increased, performance is significantly enhanced, and due to reducing the dosage of aeroge, cost is also greatly reduced.
Have excellent heat accumulation temperature control performance using the two-component heat accumulation Embedding Material of above-mentioned formula and preparation method, and
