Concave-convex side aluminum film moisture-proof pad and manufacturing process thereof

Abstract

The invention relates to a concave-convex side aluminum film moisture-proof pad and a manufacturing process thereof. The aluminum film moisture-proof pad comprises an aluminum film protective layer (1), an aluminum film layer (2), a bonding layer (3) and a moisture-proof substrate layer (4), wherein the aluminum film protective layer (1), the aluminum film layer (2), the bonding layer (3) and the moisture-proof substrate layer (4) are integrally combined sequentially from top to bottom. The manufacturing process comprises the following steps: uniformly mixing aluminum powder and an adhesive, and uniformly spraying an obtained mixture to the bonding layer; casting the aluminum film protective layer on the surface of an aluminum film; and bonding and combining a composite layer, which is composed of the aluminum film protective layer, the aluminum film and the bonding layer, on a moisture-proof pad substrate. Through the adoption of the single-side moisture-proof substrate layer (4), the thickness of the moisture-proof pad is diminished and the surface of the moisture-proof pad is easier to handle; the moisture-proof pad not only can prevent moisture but also can serve as a reflective warning plate for outdoor rescue and a reflecting light-filling plate for outdoor photography, so that multiple purposes of the pad are achieved; by arranging a connecting groove (7), the moisture-proof pad is convenient to store and carry; and the process is simple.

Description

technical field [0001] The invention relates to a concave-convex surface aluminum film moisture-proof pad and a manufacturing process thereof, belonging to the field of concave-convex surface aluminum film moisture-proof pads. Background technique [0002] Traditional moisture-proof pads rely on the properties of their own materials (such as cross-linked foam materials) to achieve moisture-proof function. In special landforms and harsh environments, the moisture-proof performance cannot fully meet the requirements. At the same time, traditional moisture-proof pads rely on the performance of their own materials or internal structure (closed air chamber) or the shape of the product (egg nest or V-shaped) to achieve thermal insulation. In special landforms and harsh environments, the thermal insulation performance cannot fully meet the requirements. , and easily damaged. When the existing moisture-proof pads have insufficient moisture-proof and thermal insulation performance, ...

AI Technical Summary

Problems solved by technology

Specifically, the different layers in the composite material must have similar processing temperatures and a sufficiently tolerant range of shrinkage, while the simple composite of ordinary foam materials and ordinary aluminum films cannot be realized. The main reason is that ordinary aluminum films are not extensible enough. It will break during processing. The aluminum film is easy to break due to stretching and other effects, which will affect the realization of the waterproof, moisture-proof and thermal insulation properties of the product.
