Description

Technical Field

[0001] The utility model relates to the technical field of road construction, and more specifically to a paint coating for road surface marking. Background Art

[0002] Road marking paint, also known as road marking paint, is a special paint used for drawing traffic markings on roads, highways, city streets and other roads;

[0003] Road marking paint generally includes hot melt marking paint, cold coating marking paint, reflective marking paint, preformed marking tape, and the existing acrylic road marking paint is a kind of road marking paint, in which glass beads and other materials are mixed to provide a reflective effect;

[0004] However, no matter what kind of road marking paint is used, it is generally necessary to consider the connection strength during spraying and the wear resistance required under long-term repeated rolling of heavy-loaded vehicles (such as: new composite marking structure, application number: CN202021328919.0), among which "using the hot-melt road marking paint layer as the first layer can effectively ensure the marking flatness and the adhesion of the asphalt concrete pavement, and the second layer of two-component marking paint can effectively exert the excellent reflective properties and anti-friction and corrosion resistance of this material", but the effect of improving the connection strength, wear resistance and other properties during spraying only by the performance provided by the road marking paint itself is not good. Summary of the invention

[0005] The purpose of the utility model is to solve the above technical problems and provide a paint coating for road marking.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model provides a paint coating for road marking, comprising a road marking paint layer, wherein the road marking paint layer is sprayed on the top of an adhesion-enhancing layer, the adhesion-enhancing layer is sprayed on the top of a primer layer, and a transparent wear-resistant layer and a topcoat layer are sprayed on the top of the road marking paint layer in sequence.

[0008] As a preferred technical solution of the utility model, the primer layer is an epoxy primer layer or a polyurethane primer layer.

[0009] As a preferred technical solution of the utility model, the adhesion-enhancing layer is an epoxy resin sealing varnish layer or a vinyl ester resin layer or a silane coupling agent layer.

[0010] As a preferred technical solution of the utility model, the wear-resistant layer is a modified acrylic resin layer.

[0011] As a preferred technical solution of the utility model, the topcoat layer is a varnish layer, and the varnish layer is an ACR polymer varnish layer.

[0012] The beneficial effects of the utility model are as follows:

[0013] A primer layer 1 of an epoxy primer layer or a polyurethane primer layer is sprayed on the road surface in advance, and an adhesion-enhancing layer 2 is sprayed on the top of the primer layer 1 to improve the bonding force when the road marking paint layer 3 is set, and then a wear-resistant layer 4 and a topcoat layer 5 are sequentially set on the top of the road marking paint layer 3 to improve the wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] Reference numerals: primer layer-1, adhesion-enhancing layer-2, road marking paint layer-3, wear-resistant layer-4, topcoat layer-5. DETAILED DESCRIPTION

[0016] like Figure 1 As shown, the utility model proposes: a paint coating for road marking, comprising a road marking paint layer 3 (the road marking paint layer 3 can be acrylic road marking paint and glass beads and other materials are mixed therein to provide a reflective effect);

[0017] The road marking paint layer 3 is sprayed on the top of the adhesion-enhancing layer 2, the adhesion-enhancing layer 2 is sprayed on the top of the primer layer 1, and the primer layer 1 is sprayed on the road surface where the marking is required;

[0018] Wherein, the primer layer 1 is an epoxy primer layer or a polyurethane primer layer, etc. {the epoxy primer layer or the polyurethane primer layer has extremely strong permeability and adhesion, and can penetrate into the micropores of the road base (such as cement, asphalt, etc.), forming a strong mechanical interlocking force, thereby enhancing the bonding strength between the paint film and the road surface};

[0019] The adhesion-enhancing layer 2 is an epoxy resin sealing paint layer, a vinyl ester resin layer, a silane coupling agent layer, etc. (it can seal the pores and cracks of the road base layer, prevent the influence of moisture and air on the performance of the paint film, and provide a uniform and smooth interface to facilitate the road marking paint layer 3 to adhere better thereto);

[0020] At the same time, the epoxy primer layer or polyurethane primer layer, epoxy resin sealer layer, and road marking paint layer 3 can undergo chemical reactions to form chemical bonds. The chemical bond binding force is much greater than the physical adsorption force, which greatly improves the stability of the overall coating system.

[0021] A transparent wear-resistant layer 4 and a topcoat layer 5 are sprayed on the top of the road marking paint layer 3 in sequence, which can provide wear resistance and weather resistance together, and the transparent layer will not block the reflective bright effect of the road marking paint layer 3;

[0022] Wherein, the wear-resistant layer 4 is a modified acrylic resin layer, etc.;

[0023] The topcoat layer 5 is a varnish layer, etc., and the varnish layer is an ACR polymer varnish layer, etc.;

[0024] The functions of using the modified acrylic resin layer and the ACR polymer varnish layer mentioned above at the same time are as follows;

[0025] Protective effect: Modified acrylic resin coating and ACR polymer varnish coating can protect acrylic road marking paint, preventing the markings from being worn and faded due to long-term exposure to the sun, rain, vehicles and other factors, thereby maintaining the clarity and reflective effect of the markings;

[0026] Enhanced wear resistance: These two layers of coating usually have good wear resistance and weather resistance, which can increase the overall wear life of the marking and ensure the long-term effectiveness of the reflective material;

[0027] Improve gloss: ACR polymer varnish coating has a higher gloss, which can improve the visual effect of the marking and indirectly enhance its reflective performance.

[0028] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
