Flexible articles based on at least one elastomeric composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for flexible elastomeric articles with textile reinforcement layers require additional time-consuming and costly adhesion-promoting steps to ensure bonding between the textile reinforcement and elastomer mixture, which can be avoided without compromising adhesion.
Innovation Solution
Incorporating dicarboxylic acid into the elastomer mixture, which directly contacts the reinforcement layer or contains textile fibers, eliminates the need for additional adhesion promoters, enhancing the adhesion between the textile reinforcement and elastomer mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesion promoters or adhesive layers are applied to textile reinforcement or fibers in upstream process steps, then adhesive bond between textile reinforcement and elastomer mixture is improved, but manufacturing time and costs increase
Solution Approach 1:
The invention extracts and eliminates the separate adhesion promoter application step from the manufacturing process. Instead of applying adhesion promoters in an upstream process step, the patent incorporates adhesion-promoting functionality directly into the elastomer mixture itself, which is then applied in a single step to the textile reinforcement. This integration removes the time-consuming separate preparation step while maintaining effective adhesion.
Solution Approach 2:
The invention merges the adhesion promoter function with the elastomer mixture. Rather than using separate adhesion promoter layers or treating the textile reinforcement separately, the patent combines the adhesion-promoting agents directly into the elastomer compound. This unified approach applies both structural and adhesive functions simultaneously, reducing manufacturing steps and costs.

3Reliability
If adhesion-promoting layers are applied to textile reinforcement or fibers, then adhesive bond is improved, but overall thickness and weight of the article increase
Solution Approach 1:
The invention merges the adhesion promoter function with the elastomer mixture. Rather than using separate adhesion promoter layers or treating the textile reinforcement separately, the patent combines the adhesion-promoting agents directly into the elastomer compound. This unified approach applies both structural and adhesive functions simultaneously, reducing manufacturing steps and costs.
Solution Approach 2:
The elastomer mixture serves multiple functions simultaneously: it provides the structural elastomeric properties needed for the flexible article, and it contains adhesion-promoting agents that ensure proper bonding to the textile reinforcement. This multi-functionality eliminates the need for separate adhesion promoter layers, reducing overall thickness and weight.
