Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adhesive manufacturing processes contribute significantly to carbon emissions due to the use of large amounts of solvent for polymerization and viscosity adjustment, and lack effective methods to reduce these emissions.
Innovation Solution
A low-carbon emission process for manufacturing eco-friendly adhesive resin involves polymerizing hydrophilic and hydrophobic monomers to form amphiphilic polymers, which are then reacted with additional hydrophobic monomers to create a colloidal adhesive resin with a core-shell structure, using a reduced amount of solvent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If large amounts of solvent are used for resin polymerization and viscosity adjustment, then the adhesive manufacturing process can proceed smoothly, but carbon emissions and energy consumption increase significantly
Solution Approach 1:
The patent changes the chemical parameters of the resin by introducing amphiphilic block copolymers with specific hydrophilic-hydrophobic ratios (1:1 to 1:15) and controlled molecular weights (10,000 to 1,000,000 g/mol). This allows the resin to achieve proper viscosity and manufacturability with significantly reduced solvent content, thereby lowering energy consumption for heating and drying while maintaining ease of manufacture.
Solution Approach 2:
The patent creates a composite adhesive resin system combining amphiphilic block copolymers (formed from hydrophilic monomers like carboxylic acid groups and hydrophobic monomers like alkyl acrylate) with reduced solvent content. This composite structure enables the resin to maintain processability and adhesion properties while reducing the solvent quantity that requires energy for evaporation, thus resolving the contradiction between ease of manufacture and energy consumption.
2Ease of manufacture
If large amounts of solvent are used for resin polymerization and viscosity adjustment, then the adhesive manufacturing process can proceed smoothly, but carbon emissions increase
Solution Approach 1:
The patent modifies the resin composition parameters by using amphiphilic block copolymers with specific hydrophilic-hydrophobic ratios (1:1 to 1:15) and controlled molecular weights. This changes the resin's physical properties to achieve proper viscosity and manufacturability with reduced solvent content, thereby reducing carbon emissions from solvent evaporation and processing while maintaining ease of manufacture.
Solution Approach 2:
The patent develops a composite resin system with amphiphilic block copolymers and reduced solvent content that maintains manufacturing smoothness while reducing harmful carbon emissions. The composite structure allows the resin to be processed and applied effectively without requiring large quantities of solvent that would generate carbon emissions during evaporation and drying processes.
3Object-affected harmful factors
If conventional eco-friendly adhesive technologies are used to eliminate harmful solvents, then the harmfulness of the adhesive is reduced, but carbon emissions from manufacturing processes like heating and drying are not addressed
Solution Approach 1:
The patent extends the parameter changes approach to address both harmfulness and carbon emissions by optimizing the amphiphilic block copolymer composition (hydrophilic-hydrophobic ratios of 1:1 to 1:15) and molecular weight (10,000 to 1,000,000 g/mol). This creates a resin that is both eco-friendly in composition and low-carbon in manufacturing, as the reduced solvent content decreases energy consumption for heating and drying while maintaining adhesive safety.
Solution Approach 2:
The patent creates a dual-benefit composite resin system that simultaneously reduces harmfulness and carbon emissions. The amphiphilic block copolymer composite structure enables the resin to be environmentally safe while requiring less solvent for processing, thereby reducing the energy consumption and carbon emissions associated with manufacturing processes like heating and drying, while maintaining adhesive performance.
