DETAILED DESCRIPTION

[0022] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0023] As noted above, there exists a long-felt need in the art for the reflective coating device and method of use that enhances the visibility of detached retread tire fragments on roadways. There also exists a long-felt need in the art for the reflective coating device and method of use that provides a reliable reflective coating capable of maintaining visibility under low-light and adverse weather conditions. Moreover, there exists a long-felt need in the art for the reflective coating device and method of use that reduces the likelihood of accidents and injuries caused by drivers inadvertently colliding with unseen retread debris.

[0024] The present invention, in one exemplary embodiment, is comprised of a reflective coating device and method of use. The disclosed invention comprises a reflective coating device and method to enhance visibility of tire fragments on roadways, thereby improving road safety. The device consists of a multi-layered reflective coating applied to the inner surface of retread tires.

[0025] The device includes a primer layer that adheres strongly to the rubber surface using chlorinated rubber or butyl-based compounds. This primer layer may also incorporate adhesion promoters, such as organosilanes or maleic anhydride grafted polymers, to strengthen bonding with the rubber and reduce the risks of peeling or delamination due to environmental stress.

[0026] A reflective layer is applied over the primer layer, containing reflective elements such as microglass beads and aluminum-coated prismatic particles. These elements, made from materials like soda-lime glass and polycarbonate or PMMA, produce retro-reflectivity to enhance visibility by reflecting light from vehicle headlights.

[0027] The reflective layer also includes a binding matrix, possibly made from polyurethane or acrylic resins, to hold the reflective elements in place despite surface wear. This matrix is selected for flexibility and adhesion to prevent cracking and ensure the reflective elements remain securely embedded under repeated impacts.

[0028] To further enhance visibility, the reflective layer may include high-contrast pigments, such as titanium dioxide for white, iron oxide for yellow and red, and fluorescent pigments for neon shades. These UV-stable pigments are uniformly dispersed within the matrix, with UV-absorbing agents like benzotriazole to resist fading from sunlight.

[0029] The reflective layer may also contain photoluminescent elements, such as strontium aluminate doped with rare earth elements, to provide passive illumination in low-light conditions by emitting a glow after absorbing ambient light. These particles are evenly distributed within the matrix to maintain consistent luminosity.

[0030] For additional protection, an optional topcoat layer can be applied to shield the reflective and photoluminescent elements from abrasion, moisture, and chemicals. This topcoat, possibly made of clear polyurethane or silicone with silica nanoparticles for added hardness, provides high resistance to road contaminants. It may also include UV stabilizers like hindered amine light stabilizers (HALS) to prevent sunlight degradation, preserving the device's reflective and photoluminescent qualities over the tire's lifespan.

[0031] The invention also includes a method for applying the device, where the primer layer is first applied to the inner surface of the tire. The reflective layer is then applied over the primer layer, followed by the optional topcoat layer, ensuring durability and effectiveness.

[0032] Accordingly, this reflective coating device and method significantly enhance visibility in low-light conditions, helping oncoming motorists detect tire fragments and avoid sudden encounters with debris, thereby reducing accidents and promoting safer driving environments.

[0033] Referring initially to the drawings, FIG. 1 illustrates a graphical view of one potential embodiment of a reflective coating device and method of use 100 of the present invention in accordance with the disclosed architecture. The device 100 is comprised of a multi-layered, specialized reflective coating applied to the inner surface of retread tires. As a result, the device 100 enhances the visibility of tire fragments on roadways, improving road safety when retread tires separate and are left scattered across a roadway.

[0034] The device 100 includes a primer layer 110 designed to establish a strong bond with the rubber surface of the retread tire. The primer layer 110 is comprised of chlorinated rubber or butyl-based adhesive compounds that have a high affinity for rubber substrates, creating a durable base. To further improve adhesion, the primer layer 110 may be comprised of adhesion promoters 112 such as organosilanes or maleic anhydride grafted polymers. These promotors 112 increase the compatibility between the rubber of the tire and the primer layer 110, enhancing the molecular bonding at the interface and minimizing the risk of peeling or delamination, even under high stress from environmental factors or impact.

[0035] The device 100 further comprises a reflective layer 120 applied over the primer layer 110. This reflective layer 120 is comprised of reflective elements 122 embedded within a robust, weather-resistant matrix. The reflective elements 122 may include microglass beads and aluminum-coated prismatic particles. Microglass beads may be comprised of soda-lime glass with a high refractive index and are preferably spherical to create a uniform distribution of reflectivity by refracting and reflecting light in all directions. Aluminum-coated prismatic particles, which may be made from polycarbonate or polymethyl methacrylate (PMMA) and coated with thin aluminum layers, are designed to achieve a retroreflective effect that intensifies light directed from headlights back towards the source, enhancing nighttime visibility.

[0036] The reflective layer 120 also incorporates a binding matrix 126 that holds the reflective elements 122 in place, maintaining their visibility despite surface wear. This matrix 126 may be comprised of polyurethane or acrylic resins that provide flexibility and excellent adhesion to the primer layer 110 while retaining elasticity. These binding matrix 126 materials are selected for their resistance to cracking and deformation, ensuring that the reflective elements 122 remain securely embedded within the reflective layer 120 even under repeated flexing and impacts.

[0037] To further enhance visibility, the reflective layer 120 may include high-contrast pigments 128 for color contrast and durability, which may include titanium dioxide (TiO.sub.2) for bright white, iron oxide for shades of yellow or red, and fluorescent pigments for neon yellow or orange. These pigments are UV-stable and may be comprised of UV-absorbing agents 129 like benzotriazole or benzophenone derivatives to prevent fading under prolonged sunlight exposure. The pigments 128 are dispersed uniformly within the matrix 126, ensuring consistent color visibility even as the tire fragment weathers.

[0038] The reflective layer 120 may also include photoluminescent elements 124 to provide passive illumination in low-light environments. These elements 124 may include strontium aluminate doped with rare earth elements such as but not limited to europium and dysprosium. These materials have high photoluminescent efficiency, absorbing ambient light or vehicle headlights and re-emitting it as a soft glow in the dark. The strontium aluminate particles are suspended uniformly within the reflective layer 120 matrix, ensuring consistent luminosity across the surface and preventing material settling that could diminish brightness over time.

[0039] For added durability and environmental protection, an optional topcoat layer 130 may be applied over the reflective layer 120. This topcoat layer 130 is designed to shield the reflective elements 122 and photoluminescent elements 124 from abrasion, moisture, and chemical exposure. The topcoat 130 may be comprised of a clear polyurethane or silicone-based coating 131 with high resistance to road contaminants such as oils, salt, and other chemicals encountered on roadways. To enhance abrasion resistance, the topcoat 130 may also be comprised of silica nanoparticles, which increase the hardness of the topcoat without sacrificing transparency or flexibility.

[0040] In addition, the topcoat layer 130 may be comprised of hindered amine light stabilizers 132 (HALS), which are UV stabilizers that prevent degradation from prolonged sunlight exposure. As a result, this prevents oxidation and breakdown of the reflective layer 120, ensuring the reflective and photoluminescent qualities of the device 100 remain effective over the extended life of the tire.

[0041] The present invention is also comprised of a method of using 200 the device 100, as seen in FIG. 2. First, a device 100 is provided comprised of a primer layer 110, a reflective layer 120 that may be comprised of a reflective element 122, a photoluminescent element 124, a pigment 128, a UV-absorbing agent 129, and a binding matrix 126, and a topcoat layer 130 comprised of a coating 131 and a stabilizer 132 [Step 202]. Then, the primer layer 110 can be applied to a surface of a tire, preferably on an inner surface of the tire that contacts a wheel rim [Step 204]. Next, the reflective layer 120 can be applied over the primer layer 110 [Step 206]. Finally, the topcoat layer 130 can be applied over the reflective layer 120 [Step 208].
