BOPET Artificial Leaf Coloring and Embossing Without PVC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional artificial leaves made of PVC release harmful substances and have insufficient color simulation, requiring high-cost paint spraying for coloration.
Innovation Solution
Manufacture artificial leaves using biaxially oriented polyester film (BOPET) with a desired color, incorporating color masterbatch and water-based ink, and embossing to achieve high simulation and environmental safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PVC material is used to make artificial leaves, then the leaves have tough, soft, and waterproof characteristics, but the production requires harmful raw materials (chlorine and ethylene) and may release harmful substances over time
Solution Approach 1:
The patent changes the material parameter from PVC to biaxially oriented polyester film (BOPET), which fundamentally alters the chemical composition to eliminate harmful substances while maintaining the required durability and safety characteristics of artificial leaves
Solution Approach 2:
The patent uses composite material structure by incorporating color masterbatch and water-based ink into the BOPET film, creating a multi-component material system that achieves both environmental safety and aesthetic requirements
2Manufacturing precision
If paint spraying is used to color artificial leaves made of PVC, then the desired color can be presented, but the cost is relatively high and the simulation degree is insufficient
Solution Approach 1:
The patent applies color masterbatch during the film production process itself, which is a preliminary action that incorporates color into the material structure before the leaf is formed, eliminating the need for subsequent expensive paint spraying while achieving better color simulation
Solution Approach 2:
The patent replaces the mechanical paint spraying process with a more efficient coloring method using water-based ink printing, which reduces production cost while improving color simulation degree through better control of color application
3Ease of manufacture
If water-based ink printing is used to color BOPET film, then the cost is reduced and environmental impact is minimized, but the printing process requires precise control of ink composition and application
Solution Approach 1:
The patent optimizes the water-based ink composition parameters by incorporating specific ratios of polytetrafluoroethylene and vegetable oil, which simplifies the printing process control while maintaining low cost and environmental friendliness characteristics
