Description

Technical Field

[0001] The utility model relates to the technical field of thin films, and more particularly to an antistatic aerogel film. Background Art

[0002] Aerogel is a form of solid matter, also known as dry gel. When most of the solvent is removed from the gel, the liquid content in the gel is much less than the solid content, or the medium filled in the spatial network structure of the gel is gas and the surface is solid, this is dry gel, also known as aerogel, which is the solid with the lowest density in the world.

[0003] Currently, when aerogel is used in clothing, the powdered aerogel first needs to be prepared and processed in a unique way, made into a film. While maintaining its characteristics, more energy efficiency that is beneficial to textiles is increased through technological means, so that the clothing fabric maintains good thermal insulation. However, most existing aerogel membrane structures are fragile and have a short service life. They cannot prevent static electricity when used on clothing fabrics and have a single function. Utility Model Content

[0008] An antistatic aerogel film comprises a substrate, a resin layer is provided on the upper surface of the substrate, an antistatic agent is provided in the resin layer, an aerogel layer is provided on the upper surfaces of the resin layer and the antistatic agent, and a PU coating is provided on the upper surface of the aerogel layer.

[0009] As a preferred solution of the present invention, a conductive layer is provided on the upper surface of the resin layer and the antistatic agent, and the aerogel layer and the PU coating are both located within the conductive layer.

[0011] As a preferred solution of the present invention, the aerogel layer is configured to be wavy.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In this solution, the substrate is bonded to the clothing fabric through an adhesive, and the aerogel layer is wrapped by a PU coating and a resin layer. The PU coating and the resin layer protect the aerogel layer to prevent the aerogel layer from breaking and shedding. The aerogel layer is wavy and has a certain tensile effect between the PU coating and the resin layer, which further prevents the aerogel layer from breaking and shedding, thereby improving the service life.

[0015] (2) In this solution, an antistatic agent is mixed in the resin layer, which protects the aerogel layer while forming a conductive layer in the upper aerogel layer and PU coating. The conductive layer can effectively eliminate static electricity on clothing fabrics. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example:

[0024] See also Figure 1-2 An antistatic aerogel film includes a substrate 1, a resin layer 2 is provided on the upper surface of the substrate 1, an antistatic agent 3 is provided in the resin layer 2, an aerogel layer 4 is provided on the upper surface of the resin layer 2 and the antistatic agent 3, and a PU coating 5 is provided on the upper surface of the aerogel layer 4.

[0025] In this embodiment, the substrate 1 carries a resin layer 2 and an antistatic agent 3. The resin layer 2 is an epoxy resin. The resin layer 2 and the antistatic agent 3 are mixed and coated on the substrate 1 and cured. The PU coating 5 is coated on the aerogel layer 4 and cured. The PU coating 5 is combined with the mixed resin layer 2 and antistatic agent 3 to wrap the aerogel layer 4 on the substrate 1 for flexible protection to prevent the aerogel layer 4 from breaking and falling into powder.

[0026] Specifically, a conductive layer 6 is provided on the upper surface of the resin layer 2 and the antistatic agent 3 , and the aerogel layer 4 and the PU coating 5 are both located in the conductive layer 6 .

[0027] In this embodiment, the resin layer 2 and the antistatic agent 3 are mixed to form a conductive layer 6 on the upper surface. The conductive layer 6 can effectively reduce the accumulation of static electricity on the clothing fabric.

[0028] Specifically, an adhesive 7 is provided on the lower surface of the substrate 1 , and a release film layer 8 is provided on the lower surface of the adhesive 7 .

[0029] In this embodiment, the base 1 is adhered to the clothing fabric through the adhesive 7 , and the release film layer 8 is made of PET material to protect the adhesive 7 .

[0030] Specifically, the aerogel layer 4 is configured to be wavy.

[0031] In this embodiment, the aerogel layer 4 is designed in a wavy shape between the resin layer 2 and the PU coating 5, which has a certain tensile strength and further prevents the aerogel layer 4 from breaking and falling into powder when subjected to stress.

[0032] Working principle: The base 1 is bonded to the clothing fabric through the adhesive 7, the resin layer 2 and the antistatic agent 3 are mixed and coated on the base 1, the aerogel layer 4 is adhered to the resin layer 2 and the antistatic agent 3 in a wavy shape, and the PU coating 5 is coated on the aerogel layer 4 to cooperate with the resin layer 2 and the antistatic agent 3 to wrap and protect the aerogel layer 4. The wrapped aerogel layer 4 can effectively withstand external forces on the fabric according to its own shape to prevent breakage and powdering. At the same time, the mixed resin layer 2 and antistatic agent 3 form a conductive layer 6 within the aerogel layer 4 and the PU coating 5, thereby effectively solving the accumulation of static electricity on the clothing fabric.
