Description

Technical Field

[0001] This utility model relates to the field of plastics technology, and more specifically, to a corrosion-resistant PU plastic structural layer. Background Technology

[0002] With the widespread use of synthetic running tracks in kindergartens, schools at all levels, and various public activity venues, the durability and corrosion resistance of these tracks have become key factors in ensuring their long-term safe use. However, some existing running track products on the market still have significant shortcomings in their corrosion protection treatment, which directly affects the overall lifespan and safety performance of the tracks.

[0003] Chinese patent CN218436457U proposes an anti-slip PU running track with an anti-corrosion layer fixedly connected to the bottom. Although the design recognizes the importance of the anti-corrosion layer in reducing the risk of corrosion after the track is buried in the soil, it lacks technical details, especially regarding the specific material selection, thickness standards, and anti-corrosion effect of the anti-corrosion layer. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a corrosion-resistant PU plastic structural layer.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A corrosion-resistant PU plastic structural layer includes a base layer, on top of which a multi-layer corrosion-resistant coating is provided. The multi-layer corrosion-resistant coating consists of a primer layer, a main corrosion-resistant layer and a topcoat layer from bottom to top, and a PU plastic layer is provided on top of the multi-layer corrosion-resistant coating.

[0006] Furthermore, the base material is a composite material of polyvinyl chloride and polyurethane.

[0007] Furthermore, a fiber reinforcement mesh is provided between the multi-layer anti-corrosion coating and the PU plastic layer.

[0008] Furthermore, the fiber-reinforced mesh is made of glass fiber or carbon fiber.

[0009] Furthermore, an anti-slip layer is provided on the top of the PU plastic layer.

[0010] Furthermore, the anti-slip layer includes several anti-slip particles and a transparent wear-resistant layer. The anti-slip particles are embedded in the surface of the PU plastic layer and covered with a transparent wear-resistant layer.

[0011] Furthermore, the main anti-corrosion layer contains anti-mildew and anti-rust agents.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model significantly improves the durability and corrosion resistance of the running track by adopting a high-strength and corrosion-resistant polymer composite material base layer, multi-layer anti-corrosion coating, fiber reinforcement mesh, high-performance PU plastic layer and unique anti-slip layer design, while ensuring excellent anti-slip effect and aesthetics, providing a safe, durable and environmentally friendly ground solution for outdoor activity venues.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 As shown, an anti-corrosion PU plastic structural layer includes a base layer, wherein the base layer can be made of a high-strength, corrosion-resistant polymer composite material, such as a composite material of polyvinyl chloride (PVC) and polyurethane (PU), to enhance the overall strength and weather resistance of the structural layer.

[0015] The top of the base layer is provided with a multi-layer anti-corrosion coating. The multi-layer anti-corrosion coating consists of a primer layer, a main anti-corrosion layer and a topcoat layer from bottom to top. The first layer is the primer layer, which is used to enhance the adhesion between the coating and the base layer. The second layer is the main anti-corrosion layer, which uses materials with excellent anti-corrosion properties, such as epoxy resin or polyurea resin, and adds an appropriate amount of anti-corrosion agents (such as mildew inhibitors, rust inhibitors, etc.). The third layer is the topcoat layer, which is used to protect the main anti-corrosion layer and improve the aesthetics.

[0016] The multi-layer anti-corrosion coating is topped with a fiber reinforcement mesh. A high-strength fiber reinforcement mesh (such as glass fiber or carbon fiber) is laid on top of the anti-corrosion layer to enhance the overall rigidity and wear resistance of the structural layer.

[0017] The fiber reinforcement layer is topped with a PU plastic layer. On top of the reinforcement layer, a high-performance PU plastic material is laid. This material should have good elasticity and wear resistance, while also taking into account its environmental friendliness and sustainability.

[0018] The top of the PU plastic layer is equipped with an anti-slip layer, which includes several anti-slip particles and a transparent wear-resistant layer. The anti-slip particles are embedded evenly on the surface of the PU plastic layer and covered with a transparent wear-resistant layer. The unique design of the anti-slip particles ensures the track's excellent anti-slip performance, guaranteeing user safety even in rainy or wet conditions. The transparent wear-resistant layer protects the anti-slip particles and prevents wear, further extending the track's lifespan and aesthetics.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
