Aqueous Binder Composition for Fibrous Materials with Recyclable Process Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional phenol formaldehyde resin (PFR) binders used in manufacturing fibrous materials like glass wool and rock wool release toxic substances such as formaldehyde and phenol, causing environmental concerns and health risks, and do not effectively prevent putrefaction of process water, leading to inefficiencies in recycling and increased costs.
Innovation Solution
An aqueous heat-curable binder composition comprising reducing sugars, amino acids, and aldehyde compounds with a minimum inhibitory concentration (MIC) of 1% or less, which undergoes the Maillard reaction to form Melanoidins, providing enhanced mechanical properties and preservative ability, allowing for the recycling of process water without putrefaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If phenol formaldehyde resin (PFR) is used as a binder, then physical properties such as adhesion strength are improved, but toxic materials such as formaldehyde and phenol are released causing environmental and health problems
Solution Approach 1:
The patent converts the harmful effect of aldehyde release into a beneficial preservative function. The aldehyde compound with MIC ≤1% not only provides binding function but also prevents putrefaction of process water, turning a previously harmful byproduct into a useful preservative agent that enables water recycling.
Solution Approach 2:
The patent changes the chemical composition parameters by using specific aldehyde compounds with minimum inhibitory concentration (MIC) of 1% or less, replacing traditional PFR with a new chemical system that maintains binding strength while eliminating toxic phenol and reducing formaldehyde release through controlled aldehyde selection.
2Reliability
If traditional PFR binder is used, then preservative effect is provided preventing putrefaction, but process water cannot be recycled due to toxic contamination and odor
Solution Approach 1:
The patent extracts and eliminates the harmful components (phenol and excessive formaldehyde) from the binder system while retaining the essential preservative function through carefully selected aldehyde compounds with MIC ≤1%, separating the beneficial preservative effect from the harmful toxic effects.
Solution Approach 2:
The aldehyde compound serves dual functions: as a binder component and as a preservative agent. The preservative effect that previously only prevented putrefaction now also enables water recycling by controlling microbial growth without the harmful side effects of traditional PFR.
3Object-generated harmful factors
If eco-friendly binder components are used, then toxic material release is reduced, but preservative effect is almost nonexistent requiring separate treatment facilities
Solution Approach 1:
The aldehyde compound performs multiple functions simultaneously: it acts as a binder component providing adhesion, and as a preservative agent preventing putrefaction of process water. This multi-functionality eliminates the need for separate treatment facilities while maintaining eco-friendliness.
Solution Approach 2:
The patent creates a composite binder system combining reducing sugars, amino acids, and aldehyde compounds with MIC ≤1%, where the aldehyde component provides both binding and preservative functions that the other components alone cannot achieve, creating a synergistic effect.
4Ease of manufacture
If PFR is used for binding fibrous materials, then manufacturing cost is reduced, but separate facilities are needed to treat process water preventing recycling
Solution Approach 1:
The binder composition provides self-service by incorporating preservative functionality directly into the binding agent. The aldehyde compound with MIC ≤1% automatically prevents putrefaction of process water, eliminating the need for external treatment facilities and enabling straightforward water recycling.
Applied Scientific Principles

AI summary
The present invention relates to aqueous binder composition capable of recycling process water and method for binding fibrous materials by using the same, and relates to an aqueous binder composition comprising one or more reducing sugars, one or more amino acids and aldehyde compounds with minimum inhibitory concentration (MIC) 1% or less and a method for binding fibrous materials by using the same. The binder composition of the present invention provides equal or better physical properties with lower price compared to traditional phenol formaldehyde resin (PFR), does not include or release toxic materials such as formaldehyde or phenol, may decrease bad odor which is a vulnerable point of traditional PFR during manufacturing and remarkably enhances the mechanical properties such as water resistance, tensile strength and hardness of the manufactured product, and is economical since process water can be recycled without putrefaction which occurs during the manufacturing process of binding of fibrous materials using the binder component since the binder solution has preservative ability.
