Solution Overview
Problem
There is a need to reduce the proportion of organically bound carbon in fossil components in synthetic resin fastening systems due to ecological, economic, and legislative reasons, and to increase the use of renewable biogenic materials to improve environmental sustainability and energy efficiency.
Innovation Solution
The development of a radically curable synthetic resin fastening system based on vinyl ester urethane resins using oligomeric or polymeric isocyanates derived from renewable biogenic sources, such as penta- or hexamethylene diisocyanates from biological raw materials like starch, with specific molecular weight distributions and functionalities, which are reacted with hydroxy-substituted (meth)acrylates to form bio-based urethane (meth)acrylate resins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fossil-based raw materials are used in synthetic resin fastening systems, then established performance and reliability are maintained, but ecological sustainability deteriorates and bio-based carbon content is low
Solution Approach 1:
The patent changes the fundamental parameter of raw material origin from fossil-based to bio-based sources. It uses plant-derived diisocyanates (such as hexamethylene diisocyanate from renewable resources) to replace petroleum-based isocyanates, thereby improving the bio-based carbon content to at least 20% while maintaining the chemical functionality and performance characteristics of the fastening system
Solution Approach 2:
The patent creates a composite material system combining bio-based diisocyanates with (meth)acrylate compounds to form urethane (meth)acrylate resins. This composite approach integrates renewable raw materials into the existing fastening system chemistry, achieving both ecological sustainability and technical performance through the synergistic combination of bio-based and synthetic components
2Object-affected harmful factors
If bio-based raw materials are increased in synthetic resin fastening systems, then ecological sustainability and carbon dioxide balance improve, but manufacturing complexity and certification requirements increase
Solution Approach 1:
The patent performs preliminary action by selecting and specifying particular bio-based raw materials (plant-derived diisocyanates with known compositions and properties) before the manufacturing process. This pre-selection ensures that the resulting urethane (meth)acrylate resins meet the minimum 20% bio-based carbon content requirement, facilitating smoother certification processes by reducing variability and uncertainty in the final product composition
3Strength
If oligomeric or polymeric isocyanates with specific molecular weight distributions are used, then bonding strength and heat resistance are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the molecular weight parameters of the oligomeric or polymeric isocyanates used in the system. By controlling the average molecular weight and ensuring that no single molecular species exceeds 50% by weight, the patent achieves improved bonding strength and heat resistance while managing the manufacturing precision requirements through well-defined parameter ranges rather than exact specifications
