Saturated Triglyceride Rubber for Tire Wet Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rubber compositions for tire components often experience inconsistent improvements in dynamic mechanical properties, making it challenging to achieve balanced enhancements in tire performance, particularly in wet traction and other performance metrics.
Innovation Solution
Incorporating a saturated triglyceride component with a melting point of at least 40°C into rubber compositions containing conjugated diene-containing polymers and reinforcing fillers, such as carbon black and silica, to improve tire tread performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rubber compositions are used with standard ingredients, then manufacturing is simple and cost-effective, but dynamic mechanical properties show inconsistent improvements and tire performance remains unbalanced
Solution Approach 1:
The patent applies parameter changes by specifying precise compositional parameters: saturated triglyceride content (1-60 parts per 100 parts rubber), melting point threshold (≥40°C), and reinforcing filler ranges (5-200 phr). These parameter constraints transform the inconsistent performance of conventional compositions into reliable, balanced tire performance across multiple metrics including wet traction and rolling resistance
Solution Approach 2:
The patent employs composite materials by combining conjugated diene-containing polymers with saturated triglyceride components and reinforcing fillers in specific proportions. This composite approach creates a synergistic rubber composition that achieves consistent improvements in dynamic mechanical properties, resolving the performance inconsistency problem while maintaining manufacturing feasibility
2Reliability
If saturated triglyceride component is added to improve wet traction, then wet traction performance increases, but composition complexity and manufacturing difficulty increase
Solution Approach 1:
The patent resolves the manufacturing difficulty by establishing clear parameter boundaries: saturated triglyceride content limited to 1-60 parts per 100 parts rubber and melting point constrained to ≥40°C. These parameter specifications guide material selection and processing, enabling consistent wet traction improvement while maintaining ease of manufacture through defined compositional ranges rather than open-ended formulation
