Polyester-Rubber Tire Bonding With an Adhesive Interlayer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adhesion between polyester materials and rubber materials in non-pneumatic tires is inadequate, limiting the durability and performance of the tires.
Innovation Solution
Incorporating a urethane-based or epoxy-based adhesive layer between the polyester and rubber components, along with optimizing the surface roughness and composition of the rubber material, specifically controlling the content of antioxidants, stearic acid, and surfactants, to enhance adhesion and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polyester material is used for the skeleton member, then cost and availability are improved, but adhesion to rubber tread member deteriorates
Solution Approach 1:
An adhesive layer is introduced as an intermediary between the polyester skeleton member and the rubber tread member. This adhesive layer mediates the bonding interface, enabling effective adhesion between the two dissimilar materials while preserving the cost and availability advantages of polyester material.
Solution Approach 2:
The tire structure employs a composite material system consisting of polyester skeleton member, adhesive layer, and rubber tread member. This composite approach combines the advantages of different materials - the cost-effectiveness of polyester with the adhesion properties of the adhesive layer and the functional properties of rubber.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly improves the adhesion and durability of the tire by creating a strong bond between the polyester and rubber materials, leading to improved weatherproofness and wear resistance.
Implementation Method 1
an adhesive layer composed of a urethane-based adhesive or an epoxy-based adhesive and provided between the member composed of a polyester material and the member composed of a rubber material
