Step 3, the preparation of functional material：By cement, flyash, pretreated diatomite, wood powder, antiseptic, mould inhibitor,
After stabilizer is uniformly mixed by proportioning, add water, after raw material are mixed into uniform sizing material, be proportionally added into light while stirring
Matter haydite and composite phase-change capsule simultaneously make it be uniformly distributed in the slurry by stirring, and well mixed slurry then is poured into mould
In tool, the form removal after die surface covers preservative film, standing is put into curing box maintenance, that is, being made has latent heat temperature adjustment and passive
The functional material of damping.
8. the preparation method of the functional material according to claim 7 with latent heat temperature adjustment and passive damping, its feature
It is, in step 3, described time of repose is 1~2 day, and curing time is 20~28 days.
9. according to the application in any described functional material of claim 1 to 6 indoors temperature and humidity regulation.
