Tire Coating Composition With Cross-Linked Dirt Repellency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire coatings based on silicone oil are not durable, wash off easily, and leave a tacky, oily residue that attracts dirt and dust, while providing a gloss that fades with washing.
Innovation Solution
A composition comprising amino functional silicone, silicone resin, and a catalyst, which forms a cross-linked structure on the tire surface, providing a non-oily, glossy finish that resists washing and dirt adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If high viscosity silicone oil is used to provide long-lasting coating, then the coating durability is improved, but the tackiness to touch increases and attracts dirt and dust
Solution Approach 1:
The patent changes the chemical parameters of the silicone coating by using amino-functionalized silicone oil instead of conventional silicone oil. This chemical modification alters the surface properties to reduce tackiness and dirt attraction while maintaining coating durability. The amino functional groups provide different surface chemistry that prevents dirt adhesion.
Solution Approach 2:
The patent creates a composite coating system by combining amino-functionalized silicone oil with other functional components. This composite approach allows the coating to simultaneously achieve durability, low tackiness, and dirt-repelling properties that cannot be obtained with single-component silicone oil alone.
2Illumination intensity
If silicone oil-based coating is applied to provide shine and color, then the aesthetic appearance is improved, but the coating washes off with rain or car wash
Solution Approach 1:
The patent modifies the chemical parameters of the coating formulation by incorporating amino-functionalized silicone oil and adjusting the composition ratios. These parameter changes enable the coating to maintain shine and color while achieving resistance to washing off, resolving the contradiction between aesthetic appearance and coating persistence.
3Illumination intensity
If conventional silicone oil coating is applied to provide gloss, then the initial shine is improved, but the gloss fades upon washing
Solution Approach 1:
The patent changes the chemical composition parameters by using amino-functionalized silicone oil instead of conventional silicone oil. This parameter change ensures that the gloss is not lost during washing, as the modified silicone oil provides better adhesion and wash resistance while maintaining optical properties.
