Problems solved by technology

[0004] The reinforced fiber material fixes the airgel material through the gaps between the fibers, and there is no other form of microscopic force between the two, so a large amount of airgel dust will fly out during the use of the airgel composite material ; In addition, the viscose fiber as a reinforcing fiber material makes the airgel composite material made harder, which is not soft enough as a cloth, and the comfort is not good; the reinforcing fiber material fixes the airgel material through the gap between the fibers, and the airgel The mass ratio of glue to reinforcing fiber is about 1:1, and the airgel content is insufficient

Embodiment 1

[0034] like figure 1 As shown, the present invention proposes a thermal insulation composite cloth, which includes a flexible base material layer 1 as a core layer, and a fabric layer 2 as a surface layer.

[0035] The flexible substrate layer 1 of the specific embodiment of the present application is a foamed sponge compounded with silica airgel.

[0036] A kind of thermal insulation composite fabric of the present application, which adopts open-pore structure foam sponge as the core base material, compared with the prior art that uses fiber material as the core base material, it is not only lighter, but also the composite fabric is softer and more comfortable; The foam sponge itself is porous and light. After compounding silica airgel, the airgel is combined in the pores of the foam sponge. Compared with the existing fiber material composite materials, the escape of airgel dust is greatly reduced. ; The mass proportion of silica airgel in the flexible substrate layer 1 is g...

Embodiment 2

[0048] This embodiment provides a method for preparing thermal insulation composite cloth, the preparation method comprising:

[0049] 1) Preparation: pad mesh cloth 3 on at least one side of the foam sponge;

[0050] 2) The foamed sponge lined with the mesh cloth 3 is prepared by a sol-gel method to obtain a foamed sponge filled with silica airgel;

[0051] 3) Take out the mesh cloth 3;

[0052] 4) Lay the upper fabric layer 2 on the surface of the foamed sponge compounded with silica airgel.

[0053] The applicant found that the foamed sponge itself is relatively thin, and its toughness is poor during the process of impregnating the foamed sponge coil with the sol, and it is easily deformed or even damaged. In order to improve, the present application pads mesh cloth 3 on at least one side of the foamed sponge as a support to hold the foamed sponge substrate. There is no double-sided mesh cloth, just a layer of mesh cloth to support the substrate during the production pro...

Embodiment 3

[0064] This embodiment provides another thermal insulation composite fabric and its preparation method.

[0065] The thermal insulation composite fabric of the specific embodiment of the application, such as figure 2 As shown, the two sides of the foam sponge as the flexible base material layer 1 are pasted with mesh cloth 3 , and the mesh cloth 3 is located between the flexible base material layer 1 and the fabric layer 2 . The 3 layers of mesh cloth can be pasted on both sides of the foam sponge by hot-melt glue.

[0066] The thickness of the mesh cloth 3 is 0.05-0.3 mm, preferably 0.05-0.15 mm. Made of Polyester or Polyester material.

[0067] The thickness of the hot melt adhesive is 0.01-0.1mm, and the thickness is more preferably 0.01-0.03mm. The material of the hot melt adhesive is preferably polyurethane hot melt adhesive.

[0068] The preparation method of the thermal insulation composite cloth comprises:

[0069] 1) Preparation: Lay mesh cloth 3 on both sides o...

Abstract

The invention discloses a heat preservation and insulation composite fabric. The composite fabric comprises a flexible base material layer and a fabric layer, and the flexible base material layer is foamed sponge compounded with silicon dioxide aerogel. The invention further discloses a preparation method of the heat preservation and insulation composite fabric. According to the heat preservationand insulation composite cloth, powder falling of an aerogel material can be effectively prevented, and the affinity of the material in contact with a human body is improved; meanwhile, the produced heat preservation and insulation composite fabric has the softness of foamed sponge and is good in comfort; the mass ratio of the silicon dioxide aerogel in the flexible base material layer is greatlyimproved, and the heat preservation and insulation effect of the heat preservation and insulation composite fabric is better.

Description

technical field [0001] The invention relates to the field of thermal insulation fabrics, more specifically, to a thermal insulation composite fabric and a preparation method thereof. Background technique [0002] Airgel materials are prepared to form fabrics. Compared with traditional thermal insulation fabrics, they will have lighter weight and smaller volume to achieve equivalent thermal insulation effects. At the same time, airgel materials also have the characteristics of super hydrophobicity. After the fabric is made, it can also avoid the impact of moisture on the thermal insulation of the fabric. [0003] Existing airgel composite materials are composed of airgel and reinforced fiber materials. For example, patent application 201910782729.1 discloses a lightweight silica airgel composite thermal insulation fabric and its preparation method. In fact, it is made of silica Airgel and viscose fiber composite. [0004] The reinforced fiber material fixes the airgel mater...
