Description

Technical Field

[0001] This utility model relates to the field of double-sided adhesive tape technology, specifically to an outdoor double-sided adhesive tape with a waterproof composite layer. Background Technology

[0002] Double-sided adhesive tape is a roll of adhesive tape made by coating elastomers or resin-based pressure-sensitive adhesives onto substrates such as paper, cloth, and plastic film. It consists of a substrate, adhesive, and a release layer. Its adhesion relies on the bonding between adhesive molecules and the adhered objects. Early adhesives used animal and plant glues and rubber, while modern adhesives are mainly polymer materials. Outdoor double-sided adhesive tape is widely used in outdoor advertising installations, building decorations, equipment fixing, and other scenarios. It needs to withstand the effects of rain, ultraviolet rays, temperature changes, and other natural environmental factors for a long time. Therefore, it has extremely high requirements for waterproofness, weather resistance, and bonding stability. However, the waterproof performance of current outdoor double-sided adhesive tape is insufficient. Rainwater can easily penetrate through the gaps in the substrate or the adhesive layer, damaging the bonding effect. To address this, we propose an outdoor double-sided adhesive tape with a waterproof composite layer. Utility Model Content

[0003] The purpose of this invention is to provide an outdoor double-sided adhesive tape with a waterproof composite layer, which has the advantage of good waterproof effect and solves the problem that the current outdoor double-sided adhesive tape has insufficient waterproof performance and that rainwater can easily penetrate through the gaps in the substrate or the adhesive layer, thus damaging the bonding effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor double-sided adhesive tape with a waterproof composite layer, comprising a substrate layer, wherein both the upper and lower surfaces of the substrate layer are coated with an adhesive layer, and a release paper layer is disposed outside the adhesive layer; the substrate layer comprises a weather-resistant protective outer layer, a butyl rubber waterproof coating, and a high-density polyethylene film layer; the butyl rubber waterproof coating is applied to both the upper and lower surfaces of the high-density polyethylene film layer, and the weather-resistant protective outer layer is located outside the butyl rubber waterproof coating.

[0005] Preferably, the release paper layer includes a release protective outer layer, a release intermediate layer, and a release functional coating. The release protective outer layer is a polyester film, the release intermediate layer is kraft paper, and the release functional coating is a silicone oil release agent coating.

[0006] Preferably, the release functional coating is located between the release intermediate layer and the weather-resistant protective outer layer, and the release protective outer layer is located on the other side of the release intermediate layer.

[0007] Preferably, the thickness of the weather-resistant protective outer layer is 0.03 mm, the thickness of the butyl rubber waterproof coating is 0.05 mm, and the thickness of the high-density polyethylene film layer is 0.1 mm.

[0008] Preferably, the thickness of the release protective outer layer is 0.02 mm, the thickness of the release intermediate layer is 0.05 mm, and the thickness of the release functional coating is 0.005 mm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The substrate layer of this utility model serves as the core supporting structure of the adhesive tape. Its internal high-density polyethylene film layer provides good structural strength and resistance to deformation. The butyl rubber waterproof coating is applied to both sides of the high-density polyethylene film layer, which can effectively block moisture penetration and form the first waterproof barrier. The weather-resistant protective outer layer is located outside the butyl rubber waterproof coating, which can resist the effects of ultraviolet rays, high and low temperatures and other environmental factors, and delay the aging of the substrate. The adhesive layers on both sides of the substrate layer ensure that the adhesive tape is firmly bonded to the bonded object. The release paper layer covers the outside of the adhesive layer and protects the adhesive layer from contamination before use.

[0011] 2. The outer protective layer of the release paper layer of this utility model is made of polyester film, which has good tear resistance and waterproof performance, preventing the release paper layer from being soaked by rainwater during storage or transportation; the middle release layer is kraft paper, which improves the overall strength of the release paper layer and prevents damage during use; the release functional coating is made of silicone oil release agent coating, which ensures that the release paper layer can be easily peeled off from the adhesive layer without leaving any impurities to contaminate the adhesive layer.
