Cable Wrapping Tape With VOC-Absorbing Adhesive Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable wrapping tapes used in automobiles often emit unpleasant odors due to volatile organic compounds (VOCs) from solvents, which are not completely mitigated by solvent-free adhesive systems, and existing odor-binding technologies are complex and ineffective.
Innovation Solution
Incorporating odor control agents like inorganic absorbents (zeolites, clays, silicates) and organic absorbents (cyclodextrin) into the adhesive coating, which can be in powder, granular, dissolved, or microencapsulated form, to absorb VOCs and other odors without compromising the tape's properties or adhesive strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solvent-based adhesive systems are used, then adhesive strength is improved, but unpleasant odors from VOCs are generated
Solution Approach 1:
The patent extracts and removes the harmful VOC component from the adhesive system by using water-based adhesives instead of solvent-based ones, thereby eliminating unpleasant odors while maintaining adhesive functionality through the water-based formulation
Solution Approach 2:
The patent employs sacrificial odor-binding particles that are incorporated into the adhesive coating. These particles are consumed during the bonding process as they absorb VOCs, providing odor control throughout the service life of the tape and replacing the need for complex active ventilation or filtration systems
2Object-generated harmful factors
If solvent-free adhesive systems are used, then unpleasant odors are reduced, but adhesive strength is compromised
Solution Approach 1:
The patent creates a composite adhesive system by combining water-based adhesive with odor-binding particles (such as activated carbon, zeolites, or cyclodextrin). This composite formulation maintains the low-VOC advantage of water-based adhesives while adding odor-absorbing functionality to compensate for the reduced adhesive strength
3Object-generated harmful factors
If odor-binding particles are incorporated into the carrier layer, then VOC absorption is achieved, but production complexity increases
Solution Approach 1:
The patent extracts the odor-binding function from the carrier layer and relocates it to the adhesive coating layer. This allows the use of simpler, more cost-effective water-based adhesives in the carrier layer while concentrating the odor-absorbing particles in the adhesive coating where they can effectively capture VOCs during the bonding process
Solution Approach 2:
The patent utilizes porous odor-binding particles (such as activated carbon or zeolites) that are incorporated into the adhesive coating. These porous materials provide high surface area for VOC absorption while maintaining a simple tape structure that is easy to manufacture and apply

Function Achieved in This Case
The odor control agents effectively absorb human and solvent-related odors without affecting the tape's resistance to media, temperature, or hand-tearability, maintaining adhesive properties and reducing production costs.
Implementation Method 1
Incorporating odor control agents like inorganic absorbents (zeolites, clays, silicates) and organic absorbents (cyclodextrin) into the adhesive coating, which can be in powder, granular, dissolved, or microencapsulated form, to absorb VOCs and other odors
