Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, and particularly relates to a non-woven fabric covered with an aluminum film. Background Art

[0002] The non-woven fabric covered with an aluminum film, also known as aluminum foil non-woven fabric, is a composite material with excellent properties, which is composed of a non-woven fabric and an aluminum foil. It has excellent waterproof, heat-proof, barrier and other properties, and is widely used in the fields of construction, automobiles, packaging, agriculture, etc.

[0003] When the existing non-woven fabric covered with an aluminum film is used for waterproofing and heat insulation, the heat insulation effect of a single-layer non-woven fabric covered with an aluminum film is limited, so that the non-woven fabric covered with an aluminum film often needs to be continuously laid in multiple layers, which makes the heat insulation use of the non-woven fabric covered with an aluminum film inconvenient. In addition, the non-woven fabric covered with an aluminum film is also easy to be damaged during use, thus affecting the heat insulation use effect of the non-woven fabric covered with an aluminum film. Therefore, we propose a non-woven fabric covered with an aluminum film. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a non-woven fabric covered with an aluminum film. By sequentially adhesively arranging a rubber-coated cloth A, a glass fiber felt, an aerogel felt, a PET plastic sheet and a rubber-coated cloth B under the aluminum film non-woven fabric body, when the aluminum film non-woven fabric body is punctured by an external force, the rubber-coated cloth A, the rubber-coated cloth B and the PET plastic sheet serve as a puncture-resistant resistance layer, which can improve the puncture resistance strength of the aluminum film non-woven fabric body and prevent the aluminum film non-woven fabric body and the subsequent composite adhesive layer from being penetrated by foreign objects and affecting the heat insulation performance. Moreover, when the aluminum film non-woven fabric body, the glass fiber felt and the aerogel felt are combined and used as a heat insulation layer, they can provide a good heat insulation effect in multiple layers. At the same time, the surface of the PET plastic sheet is provided with strip-shaped concave holes and strip-shaped convex ribs arranged as reinforcement, which can improve the support effect of the PET plastic sheet behind the aluminum film non-woven fabric body, and can effectively solve the problems in the background art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A non-woven fabric covered with an aluminum film includes an aluminum film non-woven fabric body, and also includes a rubber-coated cloth A, a polyethylene foam film layer A, a glass fiber felt, an aerogel felt, a polyethylene foam film layer B, a PET plastic sheet and a rubber-coated cloth B. The rubber-coated cloth A, the glass fiber felt, the aerogel felt, the PET plastic sheet and the rubber-coated cloth B are sequentially adhesively arranged on one side surface of the aluminum film non-woven fabric body. The polyethylene foam film layer A is filled between the rubber-coated cloth A and the glass fiber felt, and the polyethylene foam film layer B is filled between the aerogel felt and the PET plastic sheet.

[0007] Furthermore, strip-shaped concave holes that are recessed downward are arranged on the surface of the PET plastic sheet;

[0008] By adopting the above - mentioned preferred technical solution, there are strip - shaped concave holes arranged on the surface of the PET plastic sheet as the concave rib parts to enhance the strength of the sheet body.

[0009] Furthermore, on the surface of the PET plastic sheet between the strip - shaped concave holes, there are strip - shaped convex ribs arranged to protrude outward;

[0010] By adopting the above - mentioned preferred technical solution, the PET plastic sheet has strip - shaped convex ribs as the protruding reinforcement positions to reinforce the strength of the sheet body.

[0011] Furthermore, the filling thicknesses of the polyethylene foam film layer A and the polyethylene foam film layer B are the same;

[0012] By adopting the above - mentioned preferred technical solution, there is a polyethylene foam film layer A with a suitable thickness for filling and adhesion between the rubber - coated cloth A and the glass fiber felt, and there is a polyethylene foam film layer B with a suitable thickness between the aerogel felt and the PET plastic sheet.

[0013] Furthermore, the thicknesses of the rubber - coated cloth A, the glass fiber felt, the aerogel felt, the PET plastic sheet and the rubber - coated cloth B are the same;

[0014] By adopting the above - mentioned preferred technical solution, the rubber - coated cloth A, the glass fiber felt, the aerogel felt, the PET plastic sheet and the rubber - coated cloth B can be adhesively arranged layer by layer under the aluminum - film non - woven fabric body.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] In the present utility model, the rubber - coated cloth A, the glass fiber felt, the aerogel felt, the PET plastic sheet and the rubber - coated cloth B are adhesively arranged in sequence under the aluminum - film non - woven fabric body. When the aluminum - film non - woven fabric body encounters external force puncture, the rubber - coated cloth A, the rubber - coated cloth B and the PET plastic sheet serve as the anti - puncture resistance layers, which can improve the anti - puncture strength of the aluminum - film non - woven fabric body and prevent the aluminum - film non - woven fabric body and the subsequent composite adhesive layer from being penetrated by foreign objects and affecting the heat insulation performance;

[0017] And when the aluminum - film non - woven fabric body, the glass fiber felt and the aerogel felt are combined and used as the heat - insulation layer, they can provide good heat - insulation effects in multiple layers. At the same time, there are strip - shaped concave holes and strip - shaped convex ribs arranged on the surface of the PET plastic sheet for reinforcement, which improves the supporting effect of the PET plastic sheet behind the aluminum - film non - woven fabric body.
