Alcohol-Based Sprayable Coating Eliminates Corrosion and Polishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface coatings for furniture panels and similar materials are either corrosive due to high water content or require additional steps for cleaning and polishing, leading to issues with electrostatic charging and residue feel.
Innovation Solution
A sprayable, non-corrosive surface coating based on an alcoholic acetate solution with embedded function-determining substances like polytetrafluoroethylene nanoparticles, metallic powders, and inorganic pigments, using a low-water carrier to form association colloids and micelles, ensuring even distribution and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a liquid lubricant with high water content is used, then electrostatic charging is prevented, but corrosive behavior increases and cleaning becomes necessary
Solution Approach 1:
The patent changes the fundamental parameter of the carrier solution from water-based to alcohol-based (acetone, ethanol, isopropanol). This parameter change eliminates the corrosive effect while maintaining the ability to prevent electrostatic charging through the inclusion of surfactants and polyglycol components.
Solution Approach 2:
The invention extracts and removes water from the carrier solution composition entirely. By replacing water with alcohol-based solvents, the corrosive property is eliminated while the functional properties of preventing electrostatic charging are maintained through other components.
2Object-affected harmful factors
If a water-based fluid agent is used to prevent electrostatic charging, then electrostatic charging is reduced, but subsequent cleaning and polishing operations are required
Solution Approach 1:
The invention merges multiple functions into a single coating layer: electrostatic charging prevention, surface cleaning, gloss enhancement, and protective film formation. This consolidation eliminates the need for separate cleaning and polishing operations, thereby increasing productivity.
Solution Approach 2:
The alcohol-based carrier solution with surfactants and polyglycol serves multiple functions simultaneously: it prevents electrostatic charging, provides cleaning effect, enhances surface gloss, and forms a protective film. This multi-functionality reduces the total number of processing steps required.
3Object-affected harmful factors
If surfactants are added to a water-alcohol mixture, then electrostatic charging is prevented, but surface feel becomes greasy and cleaning is required
Solution Approach 1:
The patent changes the solvent parameter from water to alcohol, which fundamentally alters the interaction with surfactants and the resulting surface feel. The alcohol-based system allows surfactants to function without leaving a greasy residue, and the complete evaporation of the carrier ensures no surfactant buildup on the surface.
Solution Approach 2:
The invention extracts water from the system to eliminate the root cause of the greasy feel problem. The alcohol-based carrier evaporates completely, taking with it any surfactant associations, thereby preventing the accumulation that causes greasy surface feel.
4Manufacturing precision
If polishing agents are used to increase surface gloss, then surface finish is improved, but additional operations and time are required
Solution Approach 1:
The invention performs the gloss-enhancing action preliminarily by incorporating components in the coating solution that deposit and form a glossy protective film during the initial coating process. This eliminates the need for subsequent polishing operations to achieve the desired surface gloss.
Solution Approach 2:
The coating solution merges the functions of surface preparation, gloss enhancement, and protective film formation into a single application step. The surfactants and polyglycol components work together to create a glossy surface finish that eliminates the need for separate polishing operations.

AI summary
The invention relates to an at least temporarily acting, sprayable, noncorrosive functional surface coating on the basis of an alcoholic acetate solution. According to the invention, at least one functionally determining substance taking the form of a powder is added to a melt in order to embed the powder particles. The melt enriched in this way is subsequently converted into a solution by adding a glycol and after that, by introducing the solution into demineralized water, in particular dropwise, this acts as an agent for the formation of association colloids, which envelop the embedded powder particles, wherein the functionally determining substance thus prepared is added to the alcoholic acetate solution.
