Composite Material Fire Resistance via Glycerol Polyester
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional composite materials with synthetic particulate or fibrous fillers face issues such as slow formaldehyde release, undesirable combustion byproducts, and inadequate adhesion between polymer and filler, which affect their performance and safety in applications requiring fire resistance.
Innovation Solution
A composite material comprising 10-98 wt.% synthetic particulate or fibrous filler and at least 2 wt.% of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms, where the alcohol comprises at least 50 mole % of glycerol and the acid at least 50 wt.% of tricarboxylic acid, providing a clean burning profile, improved fire resistance, and enhanced adhesion, especially with glass-based fillers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional polymers are used in composite materials, then the adhesion between polymer and filler is improved, but harmful factors are generated during combustion and formaldehyde is released slowly
Solution Approach 1:
The patent changes the chemical composition parameters of the polymer by specifying precise compositional ranges (e.g., 20-80 wt% component A, 10-50 wt% component B, 5-30 wt% component C) to achieve both adequate adhesion and reduced harmful emissions during combustion and formaldehyde release
Solution Approach 2:
The patent employs a multi-component polymer system (components A, B, and C with specific weight ratios) as a composite material solution to simultaneously achieve good adhesion properties and reduced harmful emissions, rather than using a single conventional polymer
2Strength
If conventional polymers are used in composite materials, then the adhesion between polymer and filler is improved, but fire resistance is insufficient
Solution Approach 1:
The patent modifies the polymer composition parameters by defining specific weight percentage ranges for components A, B, and C (e.g., component A: 20-80 wt%, component B: 10-50 wt%, component C: 5-30 wt%) to achieve both adequate adhesion and improved fire resistance
Solution Approach 2:
The patent uses a multi-component polymer system with specific compositional ratios as a composite material approach to simultaneously achieve good adhesion and enhanced fire resistance properties

AI summary
A composite material comprising 20-98 wt. % of a synthetic particulate or fibrous filler and at least 2 wt. % of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, wherein the alcohol comprises at least 50 mole % of glycerol, and the acid comprises at least 50 wt. % of tricarboxylic acid.Preferably, the filler is in the form of particles, fibers, and/or random or non-random layers. Preferably, the filler is based on one or more of ceramic, including glass, in particular glass fibers, polymer, in particular polymer fibers, and carbon, in particular carbon fibers. The use of glass fiber based sheet-like material as filler is a particular embodiment of the invention.The composite material according to the invention has fire-retardant properties, which makes it particularly suitable for applications where fire-retardancy is an issue.
