Embodiment 1

[0045] Example 1: The airgel composite roll production device of the present embodiment consists of open tank 1, a receiving tank 2, a sealing glove box 3, a first rotating motor 4, a first coupling 5, a second rotating motor 6 , The second coupling 7 and the tetrafluorogenic transmission platform are composed;

[0046] Among them, the open-can 1 is composed of a cylinder 1-1, a first fixing groove 1-2, a first central rotating shaft 1-3, two first porous baffles 1-4, and the first tetrafluoro-traction belt 1-5. The first feed port 1-1-1, the first row of liquid ports 1-1-2, the first test opening 1-1-3, first measurement port 1-1-3, first measurement Port 1-1-4, first extravagant air port 1-1-5, first inert gas inlet 1-1-6, first exhaust air outlet 1-1-7; on the side wall of the open tank 1-1 Set the first fast opening door 1-1-8 parallel to the axis; the first central rotation shaft 1-3 is disposed at the axial position of the open tank 1-1, and one end of the first central rota...

Embodiment 2

[0064] Example 2: A method of producing an airgel composite material, and is different from that of Example 1: When the negative pressure extract is glue, the incurred pressure is aspected to -0.095 MPa, and the other is the same as in Example 1. The vacuum is slightly low, and the amount of sol glid is slightly low, reducing the cost of the raw material, and the airgel composite material is slightly small due to the internal airborne powder, so the thermal conductivity is substantial, but the product thermal conductivity can also achieve the market. Existing product levels.

Embodiment 3

[0065] Example 3: A method of producing an airgel composite material, in fact, in Example 1: When drying, pump the incurns to -0.099MPa, and adjust the tank temperature to 80 ° C, dry, other Example 1 was the same. The drying temperature is lowered, and the solvent in the airgel composite is slow, so the internal airgeret powder hole is kept better, it is not easy to collapse, and the obtained product has a larger surface area and the thermal conductivity is lower.

Abstract

The invention discloses a roll type production device and method for an aerogel composite material, relates to a roll type production device for a composite material, and aims to solve the technical problems of complicated operation and poor environmental protection property of an existing compounding method for the aerogel composite material. The device comprises an uncoiling tank, a coiling tank, a sealing glove box, a first rotating motor, a first coupler, a second rotating motor and a second coupler; a first central rotating shaft is arranged in an uncoiling tank body in the uncoiling tank, and a first quick-opening cabin door is arranged on the side wall; a second central rotating shaft is arranged in a rolling tank body of the rolling tank, and a second quick-opening cabin door is arranged on the side wall; and the first quick-opening cabin door and the second quick-opening cabin door are wrapped in a rubber box body by the sealing glove box. The production method comprises the following steps that vacuum impregnation is performed on a fiber base material in the uncoiling tank, then the fiber base material is conveyed into the coiling tank for aging and drying, and the aerogel composite material is obtained. The device can effectively control solvent volatilization, avoids repeated hoisting, is easy to operate and environment-friendly, and can be used in the field of aerogel composite material production.

Description

Technical field [0001] The present invention relates to a composite roll production device belonging to the field of gas gel material production. Background technique [0002] Airgel is a new type of material having a three-dimensional nanoporous structure having a porosity of 90%, with an ultra high specific surface area of ​​1000m. 2 / g above, is currently known in the solid material minimum, thermal impedance, widely used in aerospace, defense military, petroleum and chemical, rail transit, building insulation and industrial insulation. [0003] The composite process of existing prepared gas gel composites mainly includes: spray composite and roll composite methods. For example, the disclosure of China's patent is prepared in a spray composite method in China's patent using a spray composite method, and this means places the fiber substrate on the device, then spray a certain amount of sol glue, so that it is penetrated with the fiber substrate. Composite, reassemble, this me...
