Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of petrochemical-based polymers in casting compositions for products like kitchen sinks results in unsustainable practices, despite providing good mechanical and thermal properties, due to high crude oil consumption and environmental concerns.
Innovation Solution
A heat-curable biobased casting composition is developed, comprising a mixture of recycled and vegetable or animal-derived monofunctional and polyfunctional acrylic/methacrylic monomers, biobased polymers or copolymers, and inorganic filler particles, replacing petrochemical-based materials with renewable sources to create a biocomposite material with enhanced mechanical and thermal properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If petrochemical-based polymers are used in casting compositions, then good mechanical properties and thermal stability are achieved, but sustainability deteriorates due to high crude oil consumption
Solution Approach 1:
The invention changes the chemical composition parameters by replacing petrochemical polymers with biobased alternatives (polyols, polyesters from vegetable/animal origin) while adjusting the monomer ratios (10-40 wt% monomers, specific proportions of mono- and polyfunctional types) to achieve comparable mechanical properties without compromising sustainability
Solution Approach 2:
The invention creates a composite casting composition combining biobased monomers (acrylic and/or methacrylic), biobased polymers, and inorganic filler particles to achieve a material system that delivers both good mechanical properties and improved environmental sustainability
2Object-affected harmful factors
If biobased monomers and polymers are used to improve sustainability, then petrochemical consumption is reduced, but mechanical properties may deteriorate
Solution Approach 1:
The invention merges multiple biobased components (monofunctional and polyfunctional acrylic/methacrylic monomers, polyols, polyesters) with inorganic filler particles to create a synergistic composite system where the combination achieves mechanical properties comparable to petrochemical-based formulations
Solution Approach 2:
The invention applies different biobased materials with specific local functions: monofunctional monomers provide base polymerization, polyfunctional monomers enhance crosslinking and mechanical strength, polyols and polyesters contribute to flexibility and durability, while inorganic fillers provide structural reinforcement
3Object-affected harmful factors
If recycled material is used in monomer mixtures to enhance sustainability, then resource conservation improves, but material consistency may worsen
Solution Approach 1:
The invention controls the composition parameters by specifying that recycled material constitutes 20-80 wt% of the monomer mixture while maintaining defined proportions of mono- and polyfunctional monomers, ensuring consistent polymerization behavior and final material properties despite the use of recycled content
