Description

Technical fields:

[0001] This utility model relates to the field of high-performance composite material technology, specifically to a composite structure of basalt cloth surface texture and wear-resistant coating. Background technology:

[0002] Basalt fiber, as a natural mineral fiber, possesses excellent properties such as high temperature resistance, corrosion resistance, and high strength. Basalt fabric woven from basalt fiber is widely used in industrial protection and structural reinforcement. However, the surface function of traditional basalt fabric is relatively limited. Under long-term exposure to complex working conditions such as friction and impact, the surface is prone to wear and coating peeling, leading to a shortened material lifespan. Existing technologies, such as coating the surface of basalt fabric with abrasion-resistant coatings, can improve abrasion resistance to some extent, but the bonding force between the coating and the base fabric is insufficient, and there is a lack of effective buffering structures, making it difficult to cope with high-frequency, high-stress friction environments. Furthermore, the performance matching of traditional coating materials with basalt fiber in terms of high temperature resistance and corrosion resistance needs improvement, and the overall functionality of the composite structure cannot meet the requirements of high-end applications. In addition, the flat surface design of the base fabric limits the contact area between the coating and the base fabric, further affecting the interfacial bonding effect. Therefore, this invention proposes a composite structure of textured basalt fabric surface and abrasion-resistant coating to address the shortcomings and deficiencies of existing technologies. Utility Model Content:

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a composite structure of basalt cloth surface texture and wear-resistant coating to solve problems such as easy coating peeling, poor buffering effect and weak interface bonding.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A composite structure of basalt cloth surface texture and wear-resistant coating includes a wear-resistant coating and a basalt fiber woven base cloth layer from top to bottom. The basalt fiber woven base cloth layer is provided with a textured structure, and the grooves between adjacent textured structures are provided with a buffer elastic layer.

[0006] The wear-resistant coating comprises a polyurethane layer and a nano-ceramic particle layer from top to bottom, and the upper surface of the polyurethane layer is provided with a graphene layer.

[0007] Preferably, the textured structure is rhomboid, circular, regular polygonal, or corrugated, and the top surface of the textured structure has multiple micropores.

[0008] Preferably, a transition bonding layer is provided between the basalt fiber woven base fabric layer and the wear-resistant coating.

[0009] Preferably, the transition bonding layer is composed of basalt short fibers distributed in the epoxy resin layer.

[0010] Preferably, the bottom of the nano-ceramic particle layer is embedded with a ring-shaped fiber mesh, and the grooves at the top of the basalt fiber woven base fabric layer are provided with hook-shaped protrusions, which penetrate the buffer elastic layer and the transition adhesive layer and are interlocked with the ring-shaped fiber mesh.

[0011] The beneficial effects of this invention are as follows: By setting a textured structure and a buffer elastic layer within the grooves in the basalt fiber woven base fabric layer, this invention effectively improves the wear resistance and impact buffering performance of the material surface, reducing stress concentration during friction; the composite design of the graphene layer and the nano-ceramic particle layer in the wear-resistant coating endows the material with excellent wear resistance, corrosion resistance, and thermal conductivity; the interlocking structure of the hook-shaped protrusions and the ring-shaped fiber network further enhances the interlayer connection strength; the micropores at the top of the textured structure increase the contact area between the coating and the base fabric, promoting adhesive penetration; and through the synergistic function of each layer, this invention significantly improves the overall performance of the composite structure, extends the service life of the material, and meets the needs of high-end fields for high-performance protective materials.
