Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foamer systems face issues with high Global Warming Potential (GWP) values, high heat conductivity coefficients, and high energy consumption, which are not environmentally friendly and do not meet stringent environmental protection requirements.
Innovation Solution
A low-carbon environmentally-friendly foamer composition comprising 1-chloro-3,3,3-trifluoropropene (HFO-1233zd), 1,1,1,2,3-pentafluoropropane (HFC-245eb), and 1,2,2,3-tetrafluoropropane (HFC-254ca) in specific mass percentages, which are physically mixed in the liquid phase to create a foamer with reduced GWP, heat conductivity, and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If HFC-245fa is used as foamer, then foam products have smaller heat conductivity coefficient and higher strength, but GWP value is high (790)
Solution Approach 1:
The patent changes the chemical composition parameters by replacing HFC-245fa with HFO-1233zd and adding HFC-134a, transforming the foaming system from high GWP to low GWP while maintaining foam strength through optimized component ratios
Solution Approach 2:
The patent creates a composite foaming system combining HFO-1233zd, HFC-134a, and polyol, where the synergistic interaction between components achieves both low GWP and high foam strength, resolving the contradiction between environmental friendliness and mechanical performance
2Object-affected harmful factors
If HFO-1233zd is used as foamer, then GWP value is low (1) and heat insulation performance is high, but cells generated have certain defects
Solution Approach 1:
The patent introduces HFC-134a as an intermediary component that mediates between HFO-1233zd and polyol, improving cell structure quality and foam uniformity while HFO-1233zd provides the low GWP base, thus resolving the cell defect issue
3Ease of manufacture
If cyclopentane is used as foamer, then cost is low, but heat conductivity coefficient is high and energy consumption increases
Solution Approach 1:
The patent changes the thermal conductivity parameter by replacing cyclopentane with HFO-1233zd-based composition, achieving lower heat conductivity and reduced energy consumption while maintaining cost-effectiveness through optimized formulation
4Strength
If HFC-245fa/cyclopentane mixture is used, then foam strength is high, but GWP value increases and environmental friendliness decreases
Solution Approach 1:
The patent fundamentally changes the chemical composition parameters by eliminating HFC-245fa and cyclopentane, replacing them with HFO-1233zd and HFC-134a mixture that provides equivalent or superior foam strength with dramatically improved environmental credentials

AI summary
A low-carbon environmentally-friendly foamer composition is disclosed. The composition includes the following ingredients in mass percentage: 60-98.99% of 1-chloro-3,3,3-trifluoropropene, 1-39.9% of 1,1,1,2,3-pentafluoropropane and 0.01-1% of 1,2,2,3-tetrafluoropropane. The GWP value of the low-carbon environmentally-friendly foamer composition is smaller than the GWP value of a single-medium HFC-245fa. This low-carbon environmentally-friendly foamer composition has the features of environmental protection, excellent foaming performance and little modification of foaming devices, and can reduce the heat conductivity coefficient and overall energy consumption level. Therefore, the low-carbon environmentally-friendly foamer composition is the best choice for high-performance hard insulating foam, and is an ideal choice of future foamer.
