Face is eventually adding curing agent and stirs, and standing makes polymerization of epoxy resins and solidifies, and composite phase-change capsule is made；
Step 3, the preparation of functional material: by cement, flyash, pretreated diatomite, wood powder, antibacterial agent, mould inhibitor,
After stabilizer is uniformly mixed according to the ratio, while stirring plus water is proportionally added into light after raw material are mixed into uniform sizing material
Matter haydite and composite phase-change capsule are simultaneously uniformly distributed it in the slurry by stirring, and uniformly mixed slurry is then poured into mould
In tool, preservative film is covered in die surface, demoulding after standing is put into curing box maintenance, obtains with latent heat temperature adjustment and passive
The functional material of damping.
7. the preparation method of the functional material according to claim 6 with latent heat temperature adjustment and passive damping, feature
It is, in step 3, the time of repose is 1~2 day, and curing time is 20~28 days.
8. functional material according to any one of claims 1 to 5 application in temperature and humidity adjustment indoors.
