Anhydrous Fatty Acid Release Agent for Cold-Weather Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing release agents used in mining and construction industries are ineffective in cold temperatures, prone to water-related issues, and contain impurities that can contaminate materials or clog equipment, leading to material adhesion, reduced equipment efficiency, and increased operational costs.
Innovation Solution
A non-polar, anhydrous material release agent composed of Free Fatty Acids (FFAs), triglycerides, and a surfactant, which forms a Metal/Fatty Acid (MFA) salt precipitate on equipment surfaces to prevent adhesion, using a hydrolysis process to ensure stability and biodegradability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-based release agents are used, then they provide basic release properties, but they cause freezing in cold temperatures and amplify sticking problems
Solution Approach 1:
The patent changes the fundamental chemical parameter of the release agent from water-based to oil-based (specifically using vegetable oils like soybean, canola, or sunflower oil). This parameter change eliminates the freezing issue entirely since oils remain liquid at low temperatures, while still providing effective release properties through the natural lubricating and non-stick characteristics of the oil molecules.
Solution Approach 2:
The patent converts the typically harmful effect of oil (which can contaminate materials) into a benefit by using food-grade vegetable oils that are non-toxic and biodegradable. These oils provide release properties while being environmentally friendly and safe for concrete and other construction materials, turning a potential contamination issue into an eco-friendly solution.
2Reliability
If grease or tallow-based release agents are used, then they provide release properties, but they contain impurities that contaminate materials and clog equipment
Solution Approach 1:
The patent uses refined vegetable oils that are processed to remove impurities but are still biodegradable and environmentally friendly. These oils provide sufficient release properties without the heavy impurities found in grease or tallow, and can be easily disposed of or biodegraded after use, eliminating the need for complex filtration systems.
Solution Approach 2:
The patent creates a composite formulation by combining vegetable oils with specific additives (such as lecithin or other surfactants) to enhance release properties while maintaining purity. This composite approach provides better performance than pure oils alone while avoiding the contamination issues of traditional grease-based agents.
3Reliability
If conventional release agents are used, then they provide temporary release protection, but they have short shelf life and separate over time
Solution Approach 1:
The patent uses vegetable oils that are naturally homogeneous and stable formulations. By using single-phase oil-based compositions without water-oil emulsions or complex multi-component systems, the product remains uniform and does not separate or degrade over time, providing consistent release protection and extended shelf life.
Solution Approach 2:
Instead of using water-based emulsions that separate over time (the conventional approach), the patent inverts the base medium to oil-based, which is inherently more stable and resistant to separation. This inversion fundamentally solves the shelf life problem by using a medium that does not phase-separate under normal storage conditions.
4Productivity
If material build-up occurs on equipment, then equipment capacity is reduced, but cleaning and maintenance costs increase
Solution Approach 1:
The patent applies release agent to equipment surfaces before material contact occurs. This preliminary coating creates a protective barrier that prevents adhesion of concrete, asphalt, or other construction materials to the equipment, eliminating the need for subsequent cleaning operations and maintaining full equipment capacity throughout use.
Solution Approach 2:
The release agent formulation allows equipment to essentially clean itself during operation. The oil-based coating transfers minimally to materials and can be easily removed with simple rinsing or even evaporates, reducing the need for intensive manual cleaning and maintenance interventions.

Function Achieved in This Case
The agent effectively prevents material adhesion and freezing, maintains equipment efficiency, and extends its lifespan by forming a thin film barrier that repels materials, while being non-toxic and having a long shelf life.

AI summary
A release agent and method of use for preventing the adhesion of materials to equipment in various industries including construction, mining, and asphalt. The release agent can include oil, surfactant, and in increased level of free fatty acids that can combine with alkali and/or alkaline earth metals in the materials to form a metal/fatty acid salt that prevents adhesion and material build up.
