Flame-Resistant Oil-Based Fluid for Electrical Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lubricant and penetrant oils are highly flammable, posing safety risks when used near electrical components, as they can ignite and cause fires or explosions, especially when applied to corroded joints in industrial settings.
Innovation Solution
An oil-based flame-resistant organic fluid is developed, incorporating a carboxylated aromatic compound such as mellitic acid, pyromellitic acid, or trimellitic acid, which reduces flammability and provides a self-extinguishing effect when sprayed onto an electrical arc or open flame, formulated with a halogen-free oil and optional surfactants, and packaged in a pressurized aerosol can with a non-flammable propellant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lubricant and penetrant oils are used, then effective lubrication and penetration of corroded joints is achieved, but high flammability creates safety risks near electrical components
Solution Approach 1:
The patent changes the chemical composition parameters of the oil by incorporating flame-resistant additives (specifically carboxylated aromatic compounds like mellitic acid, pyromellitic acid, or trimellitic acid) into the base oil formulation. This modifies the flammability parameter while maintaining lubrication and penetration properties, directly resolving the contradiction between safety and harmful flammability factors.
Solution Approach 2:
The invention creates a composite oil formulation by combining a base oil (such as mineral oil, synthetic oil, or plant-based oil) with flame-resistant additives. This composite material approach allows the oil to simultaneously exhibit lubrication capabilities from the base oil and flame resistance from the additives, resolving the contradiction between effective performance and safety.
2Ease of operation
If oil is sprayed to penetrate corroded joints, then effective application to hard-to-reach areas is achieved, but fine droplets and fumes become highly combustible and increase fire risk
Solution Approach 1:
The patent modifies the chemical composition of the oil by adding flame-resistant additives, which changes the combustion characteristics of the sprayed droplets and fumes. This allows the oil to be effectively sprayed for penetration while the modified composition prevents the fumes from being highly combustible, resolving the contradiction between ease of application and fire risk.
3Reliability
If electrical flashovers occur near corroded joints, then high temperatures and ignition sources are generated, but this creates potential for oil ignition and fire hazards
Solution Approach 1:
The patent changes the ignition characteristics of the oil by incorporating flame-resistant additives that raise the ignition temperature and reduce flammability. This allows the oil to be safely used near electrical components where flashovers may occur, as the modified oil composition resists ignition even when exposed to high temperatures from electrical arcs, resolving the contradiction between safety and ignition risk.

AI summary
The present disclosure relates to an additive for a multi-use oil-based flame-resistant organic fluid for safely releasing corroded joints and fasteners and other general use purposes. The oil-based organic fluid includes a flame-resistant additive such as a carboxylated aromatic compound, which has a self-extinguishing effect on an arc of flame. The inclusion of carboxylated aromatic compounds release carbon dioxide when heated, causing the material to extinguish itself during ignition to resist catching on fire.
