[0065] Example one.
[0066] Such as image 3 Shown.
[0067] According to step a, and then combined with step b and step c as needed, the basic steps for preparing energy storage, heat insulation, heat preservation, cold storage, moisture-proof and moisturizing protective material are as follows.
[0068] In step a11, a commercially available high acyl gellan gum product is selected and a commercially available product obtained by microbial cultivation and extraction. Commercially available silica aerogel powder is prepared from a mixed solution of one or more of ethyl orthosilicate, methyl orthosilicate, silica sol, silicate, siloxane, and silyl ether. In this embodiment, a commercial silica aerogel powder prepared by a mixed solution of silica sol and ethyl orthosilicate is selected. The hyaluronic acid used in this example is high molecular weight sodium hyaluronate, a commercially available product obtained by microbial culture extraction.

Example Embodiment
[0082] Example two.
[0083] Such as image 3 As shown, first according to step a, and then combined with step b and step c as needed, the basic steps for preparing the energy storage, heat insulation, thermal storage, moisture-proof, moisture-proof and water-locking material are as follows.
[0084] Step a11, selecting a commercially available low-acyl gellan gum product, a commercially available product obtained by microbial culture extraction. Commercially available silica aerogel powder is prepared from a mixed solution of one or more of ethyl orthosilicate, methyl orthosilicate, silica sol, silicate, siloxane, and silyl ether. In this embodiment, a commercial silica aerogel powder prepared by a mixed solution of silica sol and ethyl orthosilicate is selected. The hyaluronic acid selected in this example is a special affinity sodium hyaluronate, a commercially available product obtained by microorganism culture extraction.
[0085] Step a12, weigh the low acyl gellan gum and th...

[0101] Example three.
[0102] Such as image 3 As shown, according to step a, and then combined with step b and step c as needed, the basic steps for preparing energy storage, heat insulation, thermal storage, moisture-proof, moisture-retaining and water-locking materials are as follows:
[0103] Step a11, select a commercially available high acyl gellan gum product, a commercially available product obtained by microbial culture extraction. Commercially available silica aerogel powder is prepared from a mixed solution of one or more of ethyl orthosilicate, methyl orthosilicate, silica sol, silicate, siloxane, and silyl ether. In this embodiment, a commercial silica aerogel powder prepared by a mixed solution of silica sol and ethyl orthosilicate is selected. The hyaluronic acid used in this example is hyaluronic acid elastomer (Hyacross), a commercially available product obtained by microbial cultivation and extraction. Hyacross is a new product developed from the natural moistur...
