Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil-resistant agents for paper-based food packaging materials do not adequately address environmental sustainability while providing sufficient oil resistance.
Innovation Solution
A modified natural product with a biobased content of ≥ 30% is used, featuring organic modifying groups such as C1-40-hydrocarbon groups or polysiloxanes to enhance oil resistance, which can be applied as an oil-resistant agent for paper, textiles, and food packaging materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional oil-resistant agents are used to provide sufficient oil resistance, then oil resistance is improved, but environmental sustainability deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the oil-resistant agent by using modified natural products with specific biobased content (≥30%) and specific modifying groups (C1-40 hydrocarbon groups or polysiloxanes), thereby achieving both oil resistance and environmental sustainability
Solution Approach 2:
The patent creates a composite material by combining biobased compounds with organic modifying groups, merging the biodegradability of natural products with the oil-resistant properties of hydrocarbon groups or polysiloxanes
2Object-affected harmful factors
If biobased materials are used to improve environmental sustainability, then environmental sustainability is improved, but oil resistance deteriorates
Solution Approach 1:
The patent modifies the physical and chemical parameters of biobased materials by introducing organic modifying groups (C1-40 hydrocarbon groups or polysiloxanes) to enhance oil resistance while preserving biodegradability
Solution Approach 2:
The organic modifying groups act as intermediaries between the biobased compound and oil, enabling the natural product to interact with oil molecules and provide oil resistance while maintaining environmental compatibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
Provided is an oil-resistant agent comprising a modified natural product which is a bio-based compound having at least one carboxyl group and in which a hydroxyl group of a carboxyl group is substituted with an R group, or a carboxyl group is substituted with an Ra group. This oil-resistant agent can give sufficient oil-resistant properties while harmonizing with the environment. R group: -X-R1 or -X-D-X'-R1. Ra group: [In the formula, X is a direct bond, -O-, -NR11-, or -S-, and R1 is a hydrocarbon group having 1-40 carbon atoms, or a polysiloxane, D is an alkylene group having 1-10 carbon atoms, X' is -C(=O)-O-, -O-C(=O)-, -C(=O)-NR12-, or -NR12-C (=O) - (where, R11 and R12 are each hydrogen or an alkyl group having 1-40 carbon atoms).]
