CO2-Based Adhesive Tape for Automotive Cable Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes for cable wrapping in automobiles face challenges in media resistance, high temperature resistance, low sound emissions, abrasion resistance, and resource-saving production, particularly with bio-based substrates that emit CO2 during composting and production.
Innovation Solution
The adhesive tape is produced using a CO2-based acrylate polymer coating derived from recovered CO2, combined with a bio-based substrate, where the substrate is made from at least 5% bio-based polymers, and the adhesive coating is applied to reduce CO2 content and enhance climate neutrality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If bio-based substrate materials are used, then resource-saving production and biodegradability are improved, but CO2 emissions during composting and production increase
Solution Approach 1:
The patent captures CO2 emissions that would otherwise be released during composting and converts them into useful chemical feedstock. The CO2 is transformed into cyclic carbonates and subsequently into polyesters through chemical synthesis, turning the harmful emission into a valuable resource for producing new adhesive tape materials.
Solution Approach 2:
Instead of allowing CO2 to be discarded into the atmosphere during composting, the patent recovers it through chemical capture processes. The CO2 is separated and purified from combustion gases, then reused as a raw material in polymer synthesis, creating a circular economy approach where waste is recovered and repurposed.
2Reliability
If adhesive tapes are designed for high abrasion resistance, then cable protection is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs composite material structures combining substrate layers with adhesive coatings formulated for enhanced abrasion resistance. The adhesive composition includes specific polymers and fillers that work together to provide protective properties while maintaining manufacturability through established coating processes.

Function Achieved in This Case
The solution results in a resource-saving, climate-friendly adhesive tape with improved abrasion resistance and reduced CO2 emissions, meeting the requirements for automotive applications while being recyclable and biodegradable.
Implementation Method 1
the acrylate-based adhesive coating is prepared. Accordingly, in this case, the adhesive coating is produced by polymerization of CO2-based acrylic acid esters
