Description

Technical Field

[0001] The utility model provides a special road paint, belongs to the technical field of road paint, and particularly relates to a special road paint that is crack-resistant and waterproof. Background Art

[0002] Road-specific coatings are specifically designed for applications such as road marking, lane demarcation, and traffic signs. They typically feature fast-drying, abrasion-resistant, and weather-resistant properties to ensure good visibility and durability in all weather conditions. These coatings must meet specific safety standards and performance requirements to accommodate high road traffic and frequent vehicle use.

[0003] Existing road paints are mostly made of a simple mixture of asphalt and pigment. After long-term rain erosion and ultraviolet exposure, this type of paint will usually crack and fade, thus affecting its normal performance. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the embodiments of the present application provide a crack-resistant and waterproof road-specific paint, thereby solving the problem of insufficient water resistance and crack resistance of the existing road-specific paint.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a special crack-resistant and waterproof road paint, including a primer, a main coating is coated on top of the primer, an anti-cracking reinforcement layer is connected to the main coating through an adhesive layer, the surface of the anti-cracking reinforcement layer is coated with a surface coating, the surface coating has an irregular hydrophobic layer, and one side of the main coating is provided with a hydrophobic plant belt placed on one side of the road.

[0006] Preferably, the primer layer is an asphalt waterproof coating.

[0007] Preferably, the primary coating is a modified polyurethane coating.

[0008] Preferably, the surface coating is composed of ultrafine fly ash and ammonium bicarbonate, and hydrophobic channels of the hydrophobic layer are formed between the ultrafine fly ash.

[0009] Preferably, the anti-cracking reinforcement layer includes but is not limited to carcass reinforcement material.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] The utility model forms a main coating and a surface coating with a material having a large gap between particles, and cooperates with a certain inclination angle of the road. When a vehicle passes by quickly, the hydrophobic layer can effectively guide the accumulated water to the hydrophobic plant belts on both sides of the road. The anti-cracking reinforcement layer not only plays an anti-cracking role, but also can assist the base coating to achieve waterproofing.

[0012] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] like Figure 1As shown, a crack-resistant and waterproof special road coating includes a primer 1, a main coating 2 is coated on the top of the primer 1, an anti-cracking reinforcement layer 3 is connected to the top of the main coating 2 through an adhesive layer, the surface of the anti-cracking reinforcement layer 3 is coated with a surface coating 4, the surface coating 4 has an irregular hydrophobic layer 41, and one side of the main coating 2 is provided with a hydrophobic plant belt 5 placed on one side of the road; wherein, the primer 1 can be an asphalt waterproof coating, the main coating 2 can be a modified polyurethane coating, the surface coating 4 is composed of ultrafine fly ash and ammonium bicarbonate, and hydrophobic channels of the hydrophobic layer 4 are formed between the ultrafine fly ashes, and the anti-cracking reinforcement layer 3 includes but is not limited to a carcass reinforcement material such as chemical fiber non-woven fabric or glass fiber mesh.

[0021] In this embodiment, the coating includes the following layer structure: the base coating 1 is composed of polymer-modified asphalt or synthetic polymer material, which is used to achieve waterproof sealing of the base layer; the anti-cracking reinforcement layer 3 is composed of a carcass reinforcement material such as a chemical fiber non-woven fabric or a glass fiber mesh to enhance the crack resistance of the coating; the main coating 2 is composed of a hydrophobic material with large particle gaps to promote rapid drainage of moisture and reduce interlayer penetration; the surface coating 4 is composed of a superhydrophobic material such as a superhydrophobic COF-VF material or a PDMS / FA superhydrophobic coating to form an irregular hydrophobic layer on the road surface. When the coating is constructed, it is combined with a certain inclination angle of the road. When a vehicle passes by quickly, the surface coating 4 can effectively guide the accumulated water to the hydrophobic plant belt 5 on both sides of the road.

[0022] It should be noted that the carcass reinforcement materials, including chemical fiber non-woven fabrics and glass fiber mesh, primarily enhance the strength and tensile crack resistance of the waterproof layer, improve the uniformity of the waterproof coating thickness, and prevent the coating from dripping. Carcass reinforcement materials are used in detailed joints to enhance the strength and tensile crack resistance of the waterproof layer. This prevents leakage caused by coating damage at detailed joints such as pipe roots, corners, and gutters, where deformation and cracking due to settlement and asynchronous structural temperature deformation can occur.

[0023] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
