Problems solved by technology

[0005] Fiber composite airgel greatly improves the mechanical properties (strength, formability, flexibility) of airgel, but due to the splitting effect of fibers, airgel is mostly embedded in the gap of fiber body in the form of small particles, and the small surface Particles are easy to fall out during production and use
Nanoscale small particles are potentially harmful to humans, and as the particles fall off, the performance of airgel-based materials will also decrease, which will affect its use effect and lifespan
At present, there are no other literature and patent reports that can prevent airgel-based materials from falling powder.

Embodiment 1

[0020] Example 1 : Manufacture of glass fiber fireproof cloth veneered airgel sandwich panel

[0021] The airgel-based substrate is rolled to remove powder or particles that are easy to fall off on the surface. Next, the surface of the pretreated airgel-based material 1 is evenly coated with a silicate or phosphate inorganic binder, and the glass fiber-based fireproof cloth 2 is uniformly and evenly bonded to the outer surface of the airgel-based material. After curing, the glass fiber fireproof cloth veneered airgel sandwich panel is obtained. The product schematic diagram is as follows figure 2 shown. The density of the sandwich panel is about 170 kg / m 3 , the thermal conductivity is only 0.015 W / m.K, which is the same performance parameter as the airgel substrate.

Embodiment 2

[0022] Example 2 : Manufacture of Teflon fireproof cloth veneer airgel interlayer sleeve block

[0023] The airgel-based substrate is rolled to remove powder or particles that are easy to fall off on the surface. Cut the board into the designed size, and then coat the oxide inorganic binder on the Teflon fireproof cloth 2 with the designed shape and size, and compound it with the cut airgel board 1 according to the design. After curing, the Obtain Teflon fireproof cloth veneer airgel interlayer sets, the product structure diagram is as follows image 3 shown. The block can be directly wrapped on the T-shaped structure for efficient heat insulation. The basic material density of the block is about 170 kg / m 3 , the thermal conductivity is only 0.015 W / m.K, which is the same performance parameter as the airgel substrate.

Embodiment 3

[0024] Example 3: Manufacture of asbestos fireproof cloth veneer airgel interlayer felt

[0025] The airgel-based felt is rolled to remove powder or particles that are easy to fall off on the surface. Then, the borate inorganic binder is coated on the asbestos fireproof cloth, and it is uniformly and evenly bonded to the outer surface of the airgel-based material. After curing, the airgel interlayer felt covered with asbestos fireproof cloth can be obtained. The interlayer felt has a smooth appearance, no powder shedding, and increased toughness.

Abstract

The invention belongs to the field of heat insulation and sound-proof material manufacturing, and in particular relates to a production method of a no-powder-falling interlayer structure super heat insulation gas gel composite material. According to the invention, inorganic fireproof cloth is pasted on the outer surface of a nano porous gas gel material; the performances of light quality, super heat insulation and the like of the gas gel material are kept, and meanwhile the problem of easiness in powder falling is solved, and nano dust is prevented from generating during the production and using process of the gas gel material, so that the gas gel material is more safe, healthy and environment-friendly, and compared with the non-composite gas gel material, the gas gel material is more even and uniform, and the appearance is more beautiful. The no-powder-falling interlayer structure super heat insulation gas gel composite material provided by the invention has the characteristics of chip and easily obtained raw materials, safe and simple production process, low cost and the like; the obtained material has the advantages of excellent nano porous material heat insulation performance and durable common material, and is widely applied to the heat insulation field of ship cabins, vehicle bodies, airplanes, industrial pipelines, building wall bodies and the like.

Description
