Coconut Fiber Flooring Composition for VOC-Free Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flooring materials, such as those using waste tire chips or recycled rubber, often release harmful substances like VOCs and have low adhesiveness, leading to reduced durability and elasticity over time, making them unsuitable for environmentally friendly and long-lasting applications.
Innovation Solution
A composition for flooring incorporating coconut fiber with acrylonitrile-butadiene latex, vulcanizing agents, zinc oxide, antioxidants, and calcium carbonate, which is applied and compressed to create a durable, weather-resistant, and VOC-free surface without the need for organic binders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional materials such as waste tire chips or recycled rubber are used for flooring, then elasticity and cushioning performance are improved, but harmful substances such as VOCs are released and adhesiveness is low
Solution Approach 1:
The patent changes the material parameter from conventional recycled rubber/tire chips to coconut fiber, which fundamentally alters the chemical composition to eliminate VOC emissions while maintaining the physical elasticity and cushioning properties needed for flooring applications
Solution Approach 2:
The patent creates a composite material system combining coconut fiber with specific polymers (polyacrylic acid, polyacrylonitrile, or acrylic acid) and crosslinking agents to achieve both environmental friendliness and mechanical performance, replacing the conventional single-material approach
2Ease of operation
If conventional elastic packaging materials are used, then sufficient elasticity is imparted to improve walking feeling, but harmful substances are released at high temperatures
Solution Approach 1:
The patent changes the material composition parameter to use coconut fiber-based composite materials that maintain elastic properties for comfortable walking while being thermally stable and free from harmful substance emissions at elevated temperatures
Solution Approach 2:
The patent uses coconut fiber, an abundant and renewable natural resource, as a sustainable alternative to conventional synthetic materials, aligning with environmentally friendly and disposable-friendly construction trends
3Strength
If composite materials with different properties are adhered together, then elastic packaging is achieved, but adhesiveness is low and flooring is easily broken
Solution Approach 1:
The patent merges coconut fiber with specific polymers and crosslinking agents into a unified composite material system, eliminating the need for separate adhesive layers and achieving strong internal bonding that prevents flooring breakdown
Solution Approach 2:
The patent introduces crosslinking agents as intermediary substances that create strong chemical bonds between coconut fiber and polymer matrices, significantly enhancing adhesiveness and overall structural reliability of the flooring
