[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 The present invention provides a wear-resistant foam strip, which includes, from the outside to the inside, a wear-resistant outer layer 1, an elastic core layer 2, and a reinforcing layer 3. The elastic core layer 2 is provided with a plurality of through holes 4.

[0024] The surface of the wear-resistant outer layer 1 is provided with a self-healing coating 5;

[0025] The wear-resistant outer layer 1 is incorporating stainless steel microfibers.

[0026] The wear-resistant outer layer 1 is an ultra-high molecular weight polyethylene wear-resistant layer, the elastic core layer 2 is an EPDM rubber foam core layer, and the reinforcing layer 3 is a glass fiber reinforced polyurethane fiber cloth.

[0027] The wear-resistant outer layer 1 has a micron-level concave-convex mesh texture, and wear-resistant particles 6 are embedded in the wear-resistant outer layer 1. The wear-resistant particles 6 are ceramic or silicon carbide particles.

[0028] Graphene nanosheets or molybdenum disulfide nanoparticles are added to the elastic core layer 2.

[0029] This wear-resistant foam strip employs a multi-layer composite structure to achieve excellent wear resistance. The outermost layer is an ultra-high molecular weight polyethylene wear-resistant layer, which itself has good wear resistance. At the same time, stainless steel microfibers are mixed into this layer to further enhance the strength and toughness of the wear-resistant outer layer 1. This allows the wear-resistant outer layer 1 to effectively resist external impacts and reduce wear when the foam strip is subjected to friction.

[0030] The self-healing coating 5 on the surface of the wear-resistant outer layer 1 can release a repair agent when minor scratches or damage occur on the coating surface. This agent will automatically fill the wear gap and continuously protect the wear-resistant outer layer 1.

[0031] The micron-level uneven mesh texture set on the wear-resistant outer layer 1 increases the contact area with the friction surface, disperses the friction force, and reduces the degree of local wear; while the embedded ceramic or silicon carbide wear-resistant particles 6, with their extremely high hardness, can effectively resist external friction, forming a hard protective barrier on the wear-resistant outer layer 1.

[0032] The middle elastic core layer 2 is an EPDM rubber foam core layer. The multiple through holes 4 distributed on it give it good elasticity and cushioning performance. When the foam strip is squeezed or collided, the through holes 4 can absorb and disperse the external force, reducing the damage of the external force to the overall structure.

[0033] Meanwhile, the graphene nanosheets or molybdenum disulfide nanoparticles added to the elastic core layer 2 further enhance the toughness of the elastic core layer 2 and extend its service life.

[0034] The innermost reinforcing layer 3 is made of glass fiber reinforced polyurethane fiber cloth. This layer provides stable structural support for the foam strip, enhances the overall strength and rigidity of the foam strip, prevents the foam strip from deforming or breaking due to external forces during use, and ensures that each layer works together stably.

[0035] The glass fiber reinforced polyurethane fiber cloth reinforcement layer 3 provides stable support for the foam strip, enabling the foam strip to maintain a good structural shape even in complex usage environments, and ensuring the stable performance of functions such as sealing and shock absorption.

[0036] With its excellent wear resistance, cushioning, and structural stability, this foam strip is suitable for various fields such as automobile manufacturing, building doors and windows, and electronic equipment sealing. It can meet the stringent performance requirements of foam strips in different scenarios and has broad market application prospects.
