Embodiment 1

[0066] like image 3 shown.

[0067] First follow step a, and then combine with step b and step c according to needs, the basic steps for preparing energy storage, heat insulation, cold storage, moisture-proof and moisture-proof protective material are as follows.

[0068] In step a11, a commercially available high acyl gellan gum product is selected, which is a commercially available product obtained by extracting from microbial culture. Commercially available silica airgel powder is prepared from one or a mixed solution of ethyl orthosilicate, methyl orthosilicate, silica sol, silicate, siloxane, and silicon ether. In this example, a commercial silica airgel powder prepared from a mixed solution of silica sol and tetraethyl orthosilicate was selected. The hyaluronic acid used in this example is high-molecular-weight sodium hyaluronate, a commercially available product obtained by extracting microorganisms.

Embodiment 2

[0083] like image 3 As shown, first follow step a, and then combine with step b and step c as required, the basic steps for preparing energy storage, heat insulation, cold storage, moisture-proof, moisture-proof, moisture-retaining and water-locking materials are as follows.

[0084] In step a11, a commercially available low-acyl gellan gum product is selected, which is a commercially available product obtained from microbial culture and extraction. Commercially available silica airgel powder is prepared from one or a mixed solution of ethyl orthosilicate, methyl orthosilicate, silica sol, silicate, siloxane, and silicon ether. In this example, a commercial silica airgel powder prepared from a mixed solution of silica sol and tetraethyl orthosilicate was selected. The hyaluronic acid used in this example is sodium hyaluronate with special affinity, which is a commercially available product extracted from microbial culture.

Abstract

The invention provides a novel aerogel multifunctional material and a preparation method thereof. The multifunctional aerogel composite is prepared from gellan gum, hyaluronic acid as well as derivatives or mixture of the gellan gum and the hyaluronic acid, aerogel, a novel light-sensitive material, a novel solvent or novel ionic liquid or a novel mixed solvent formred by the above solvents or essential oil and the like by a high-energy photocuring method. The composite material has the characteristics of low density, low heat-conducting coefficient, high weather resistance, environmental friendliness and the like. A functional carrier or a functional material coated with the composite material has high heat-isolating, heat-insulating, cold-accumulating, moisturizing, moisture-proof, moisture-retaining and anti-haze characteristics, and the characteristics and the use range of the materials can be improved. The multifunctional material is extremely widely applied, and can be widely applied in the fields of haze prevention and control, disease diagnosis and treatment, medicine, military industry, chemical industry, spaceflight, navigation, aviation, high-speed train, paper making, printing, water treatment, agriculture and animal husbandry, a cold chain system, food and cosmetic safety.

Description

technical field [0001] The invention belongs to the field of chemical materials for heat insulation, heat preservation, cold storage, moisture retention and protection, and specifically relates to a novel multifunctional material for energy storage, heat insulation, heat preservation, cold storage, moisture resistance, moisture retention, water locking and protection and a preparation method thereof. . Background technique [0002] Gellan gum is currently one of the food gums with superior performance in the world, which integrates thickening, suspension, emulsification, stabilization, antibacterial, and controlled release. It has extremely high commercial profits and market prospects. Gellan gum is a polysaccharide colloidal gel obtained by biological fermentation. It has the advantages of low dosage, high transparency, strong aroma release ability, acid and alkali resistance, and has anti-microbial and anti-enzymolysis effects, so gellan gum is used The prepared gel can r...
