Mixture, then preplasticizing mixture and foaming agent, coupling agent successively plasticated after mixing, is broken to get foaming PVC
Grain；
Step 3: preparation foaming shaping phase-change material: by eutectic mixture, heat filling, fire retardant and foaming PVC
Injection molding forms a kind of foaming figuration composite phase-changing material to grain after mixing.
Above-mentioned preparation method, also has the feature that, the first solid fatty acids, the second solid fatty acids in step 1
One of difference, and be respectively selected from stearic acid (SA), myristic acid (MA), palmitinic acid (PA) or lauric acid (LA).
The mass ratio of solid fatty acids is obtained in the present invention with binary of fatty acids lowest total of the melting point theoretical calculation, thus this Shen
Please in no longer this is repeated.
Above-mentioned preparation method, also has the feature that, in step 2 in terms of polyvinyl chloride resin quality plasticizer, foaming agent
And the additional amount of coupling agent is (1-25wt%): (1-5wt%): (1-3.75wt%).
Above-mentioned preparation method, also has the feature that, preplasticizing temperature is 90-110 DEG C, when preplasticizing in step 2
Between be 10-15min.
Above-mentioned preparation method, also has the feature that, plasticating temperature is 160-170 DEG C, plasticates the time in step 2
For 5-10min.
Above-mentioned preparation method, also has the feature that, in step 3 in terms of polyvinyl chloride resin quality heat filling and fire-retardant
The additional amount of agent is (1-7.5wt%): (1-3.75wt%), and low in terms of the figuration composite phase-changing material quality that foams in step 3
The addition of eutectic mixture, foaming PVC particle (containing polyvinyl chloride resin, plasticizer, foaming agent, coupling agent, heat filling and fire retardant)
Amount is (50-52wt%): (50-48wt%).
Eutectic mixture in the present invention, foaming PVC particle additional amount obtained using orthogonal experiment, under above-mentioned additional amount

The second aspect of the invention is to provide a kind of foaming setting compound phase prepared according to above-mentioned preparation method
Become material.
The beneficial effect of above scheme is:
1), the present invention in as body of phase change material Fatty Acid Binary eutectic phase transition temperature 30 DEG C-
Between 55 DEG C, and its enthalpy of phase change numerical value is higher, and suitable for the requirement of room temperature heat reservoir, the heat that can be used to increase building is lazy
Property, reduce house temperature fluctuation achieve the purpose that building energy conservation to reduce the air conditioner load of building；
2), the backing material foaming PVC that the present invention selects is that one kind has excellent performance reliable material, with other polymers phase
Than foaming PVC intensity with higher and preferable tensile property, so that foaming figuration composite phase-changing material provided by the invention
Possess more excellent mechanical property and machining property, and hot property is stablized；Meanwhile it is abundant porous inside foaming PVC
Phase-change material can be firmly fixed in foam structure by shape structure, greatly reduced leakage, made it when in use can be straight
It connects and uses into the water, do not need to encapsulate compared to traditional plastic material HDPE, it is possible to reduce 20-30% using storage container
Weight, greatly reduce use cost.
3), in the present invention using injection molding method preparation foaming figuration composite phase-changing material, reaction condition is mild, processing
