Description

Technical Field

[0001] The utility model relates to a coating structure for a traffic sign line. Background Art

[0002] Common coating materials and processes for traffic markings are: 1) Hot melt coating: This is the most widely used material at present. Its main components are petroleum resin, pigment, filler, etc. It needs to be heated to above 200°C for construction. The advantages are low cost, high construction efficiency, and good reflective effect both during the day and at night. 2) Cold spray coating: There are mainly two types of acrylic and polyurethane, which can be constructed at room temperature, with low volatile organic compound (VOC) content and good environmental performance. 3) Solvent-based coating: The main component is acrylic resin, and the solvent is usually xylene. The price is low, but the VOC content is high, and it is gradually replaced by environmentally friendly water-based coatings. 4) Water-based coatings: The ingredients are usually acrylic emulsions or polyurethane emulsions, etc., which do not contain solvents, are environmentally friendly during construction, and are currently developing rapidly. The disadvantages are that the price is relatively expensive, the marking thickness is low, and the wear resistance is poor.

[0003] At present, the main problems with traffic markings on highways with high traffic volume are insufficient wear resistance, durability and reflectivity. Utility Model Content

[0004] The utility model aims to provide a coating structure for a traffic sign line. Through the designed composite coating structure, the traffic sign line has the characteristics of high durability, high wear resistance, high reflectivity and easy construction.

[0005] To this end, a traffic sign coating structure is provided, including: an adhesive layer, comprising an epoxy resin-polyurethane composite coating; an intermediate layer, comprising ceramic particles and a first acrylic resin coating wrapped on the ceramic particles; a reflective layer, comprising glass beads and a second acrylic resin coating wrapped on the glass beads; and a protective layer, comprising a polyurethane coating or a fluorocarbon varnish coating.

[0006] The thickness of the adhesive layer is usually 0.5 mm to 1 mm. The thickness of the intermediate layer is usually 1 mm to 1.5 mm. The thickness of the reflective layer is usually 0.5 mm to 1 mm. The thickness of the protective layer is usually 50 μm to 100 μm.

[0007] The above-mentioned traffic sign coating structure has the following characteristics:

[0008] First, multi-layer composite structure design: four functional layers are used, namely adhesive layer, middle layer, reflective layer and protective layer. Different materials are used in each layer to give full play to their respective advantages and work together to achieve comprehensive performance of high durability, high wear resistance, high reflectivity and easy construction. This layered composite design concept is rare in traffic marking coatings.

[0009] Second, material selection and optimized combination: suitable materials are selected and optimized for each functional layer. For example, the bottom layer uses epoxy resin-polyurethane composite coating, which takes into account both adhesion and durability; the middle layer uses acrylic resin + ceramic particles, which takes into account wear resistance and construction speed; the reflective layer uses acrylic resin + high-refractive glass beads to ensure excellent reflective performance; the protective layer uses polyurethane or fluorocarbon varnish to provide long-term protection. This optimized combination of multiple materials can give full play to the advantages of each material and maximize performance.

[0010] Third, the balance of comprehensive performance: while pursuing high wear resistance, high reflectivity and other properties, it also takes into account other performance indicators such as the coating's adhesion, weather resistance, and chemical resistance, thereby achieving a balance in the coating's comprehensive performance, improving the coating's long-term service life, and reducing maintenance costs.

[0011] In short, the coating structure of the traffic marking line takes into account wear resistance, durability, and reflectivity, and is suitable for traffic marking line construction on highways with high traffic volume.

[0012] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through practice.
