Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes face issues such as oxidation, degradation, unsuitable color, viscoelastic flow, and edge sticking, leading to performance limitations and resource inefficiencies in production and application.
Innovation Solution
Functionalization of the adhesive layer surfaces, particularly at edges, through methods like crosslinking or coating with materials like polyurethane dispersions, silanes, or epoxidized polybutadiene to achieve non-stickiness, reduce adhesive strength, and enhance stability and protection against environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side plates with hydrophobic silicon coating are applied to prevent edge sticking, then edge sticking is prevented, but resource consumption increases due to additional carriers and coating materials
Solution Approach 1:
The invention extracts and eliminates the side plates from the adhesive tape structure, achieving edge protection through a different mechanism (functionalization of the adhesive layer itself rather than external protective plates), thereby reducing material consumption while maintaining reliability
Solution Approach 2:
Instead of using side plates as intermediaries to prevent edge sticking, the invention directly modifies the adhesive layer at the edges through functionalization, creating a non-sticky zone that prevents self-adhesion without requiring additional carrier materials
2Reliability
If adhesive layers are coated to prevent oxidation and degradation, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The invention applies functionalization to the adhesive layer edges during or after the coating process, preparing the edges in advance to resist oxidation and degradation before the adhesive tape is put into service, thereby improving stability without requiring complex multi-step manufacturing processes
3Object-affected harmful factors
If functionalization layer is applied to adhesive layer surfaces, then protection against environmental factors is enhanced, but production steps increase
Solution Approach 1:
The invention changes the chemical or physical parameters of the adhesive layer surface through functionalization, creating a protective layer that enhances resistance to environmental factors such as UV radiation, oxidation, and moisture, while integrating this step into existing production workflows

AI summary
The invention relates to a method for producing an adhesive product (1) comprising at least one adhesive layer (2) with two cover surfaces (2a, 2b) connected via edge surfaces (2c), wherein the cover surfaces (2a, 2b) and the edge surfaces (2c) form the surface (O) of the adhesive layer (2). To improve the quality of the adhesive product (1), and in particular to minimize the effort required for its transport, it is proposed that the surface (O) of the adhesive layer (2) be subjected to functionalization, in particular passivation, forming a layer (3) that extends at least partially over the surface (O) of the adhesive layer (2).
