Waste Powder Coating Road Patching Composite
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powder coating paint operations face significant paint loss due to uncontrolled deposition and difficulty in recovering unused particles, leading to substantial waste sent to landfills.
Innovation Solution
A method utilizing excess or waste powder coating material mixed with a filler, such as sand or pea gravel, applied to repair surfaces like roads and sidewalks, where the mixture is cured by heating to bind the powder coating with the filler, creating a durable and waterproof patch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If powder coating paint is applied to products, then a high quality paint finish is achieved, but uncontrolled deposition causes paint particles to settle and coat objects and floor, resulting in substantial paint loss
Solution Approach 1:
The patent converts the harmful waste powder coating material that settles in the paint booth into a useful repair material for roads and surfaces. The waste powder coating is mixed with filler materials to create a durable patching composition that repairs potholes and cracks, thereby eliminating the need to send it to landfills while creating a valuable product.
Solution Approach 2:
Instead of discarding the excess powder coating material to landfills, the patent recovers it by collecting and storing the waste powder coating in containers. This recovered material is then reused as the base component of the patching composition, significantly reducing material waste and environmental impact.
2Ease of manufacture
If waste powder coating material is sent to landfills, then disposal is simplified, but substantial amount of paint is lost and environmental harm is caused
Solution Approach 1:
The patent transforms the harmful waste disposal problem into a beneficial resource recovery opportunity. By creating a marketable patching material from waste powder coating, the system eliminates landfill disposal while generating economic and environmental value from what was previously considered waste.
Solution Approach 2:
The waste powder coating material serves multiple functions: it acts as the binder in the patching composition, provides the curing mechanism through heat activation, and serves as a cost-saving alternative to traditional road repair materials. This multi-functionality maximizes the utility of the recovered waste material.
3Ease of operation
If traditional road repair materials are used, then repair is straightforward, but the quality and durability may not be optimal
Solution Approach 1:
The patent utilizes the temperature-dependent properties of powder coating materials, which are designed to cure at specific temperatures. By applying heat from torches or other heating devices, the powder coating transitions from a dry powder state to a melted, flowing state that can penetrate and bond with the substrate, then cures to form a durable repair. This parameter change enables the material to achieve optimal bonding and repair quality.
Solution Approach 2:
The patching composition is a composite material combining waste powder coating with filler materials such as sand, gravel, or other aggregates. This composite structure provides both the adhesive/binding properties of the powder coating and the structural integrity provided by the filler materials, resulting in a repair material that is both strong and durable.
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
This approach effectively recycles waste powder coating material, producing a high-quality, long-lasting repair that reduces waste and provides a waterproof surface, preventing damage from rain and ice.
Implementation Method 1
The mixture is cured by heating the mixture to the point where the powder coating melts and binds the powder coating with the filler and the surface needing repair
Implementation Method 2
The mixture is cured by heating the mixture to the point where the powder coating melts and binds the powder coating with the filler and the surface needing repair

AI summary
A product and method for repairing holes and cracks in roads, parking lots, sidewalks and other similar surfaces using a mixture of powder coating (i.e. dry paint) and a filler. The first step is to obtain the powder coating material. Any suitable powder coating material may be used, however, it is preferable to use the excess or waste powder coating material obtained from a powder coating operation. The next step is to mix the powder coating material with a filler, such as sand, pea gravel, or another suitable material. After the components are mixed together, it is applied to a surface needing repair such as a pothole in a road or a crack in a sidewalk. The mixture is cured by heating the mixture to the point where the powder coating melts and binds the powder coating with the filler and the surface needing repair. It may be cured before or after it is applied to the surface needing repair. After the mixture cures, the result is a high quality patched surface.
