Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a silicon carbide coated abrasive cloth suitable for grinding stone and fiberglass products. Background Technology

[0002] Coated abrasive cloth, as a common grinding tool, is widely used in surface grinding, polishing, and cleaning operations on metals, wood, stone, and composite materials. Abrasive cloth used for grinding stone and fiberglass products, in particular, needs to possess extremely high tensile strength, tear resistance, durability, and heat dissipation. This is because these materials have high hardness and high grinding resistance, and are mostly used in dry grinding, generating a large amount of heat and dust, resulting in significant wear and tear on the abrasive cloth substrate.

[0003] In existing technologies, ordinary abrasive cloth typically uses pure cotton, polyester, or composite fabric as the base material. Its tensile strength is limited, making it prone to tearing and breakage during high-speed, high-pressure grinding operations. This leads to a shortened product lifespan, increased replacement frequency, and higher costs. While some high-end products use fiberglass mesh or single-type synthetic fiber mesh for reinforcement, their flexibility is poor, making them easily broken. Furthermore, their bonding strength with the base material is insufficient, and they are prone to delamination under long-term stress, affecting safety and grinding performance.

[0004] On the other hand, traditional abrasive cloths, when fixed to the rotary mechanism of automatic grinding equipment (such as grinding discs and sanders), often rely on Velcro fasteners or simple pressure-sensitive adhesive on the back. During high-load grinding, these fixing methods are prone to slippage and detachment, leading to low power transmission efficiency and potentially causing safety accidents. Furthermore, existing abrasive cloths have poor heat dissipation performance; heat accumulation in the grinding area easily causes aging of the substrate and adhesive, resulting in premature abrasive shedding and further reducing the product's effective lifespan.

[0005] Therefore, among the many grinding equipment currently available, there is a need for abrasive cloth that combines extremely high tensile and tear strength, excellent heat dissipation, ultra-long lifespan, and reliable anti-slip and fixing capabilities to meet the needs of efficient and high-intensity operations on difficult-to-grind materials such as stone and fiberglass. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a silicon carbide coated abrasive cloth that is high-strength, tear-resistant, has efficient heat dissipation, is anti-slip, and has a long service life, suitable for polishing stone and fiberglass products.

Silicon carbide abrasive is sprayed onto the surface of the tensile-strength reinforcing layer; Polyurethane is sprayed onto the surface of an aramid-reinforced mesh without steel wire mesh to form an anti-slip layer for contact with external rotating mechanisms.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the silicon carbide coated abrasive cloth suitable for polishing stone and glass fiber products described above, wherein the mesh size of the aramid reinforced mesh is smaller than the rhombic mesh size of the planar base cloth.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products described above, wherein the wire mesh is a copper-plated wire mesh with a wire diameter of 0.1-0.3mm.

[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products, as described above, wherein the thickness of the anti-slip layer is 0.2-0.5mm.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows: the silicon carbide coated abrasive cloth is composed of a flat base cloth, aramid reinforcing mesh, steel wire mesh, silicon carbide abrasive, and polyurethane composite.

[0016] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0017] Example 1, referring to Figure 1-4 A silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products, comprising: A flat base fabric 1 woven into a diamond-shaped grid can be selected according to the usage requirements. Aramid reinforced mesh 2 is hot-pressed onto the front and back of the planar base fabric 1 to enhance the tensile strength of the planar base fabric 1; 3. The surface of the wire mesh is fixed to the surface of one layer of reinforcing mesh by spot welding, thereby providing rigid support and fatigue resistance; The aramid reinforced mesh 2 and the steel wire mesh 3, which are fixed together by spot welding, form a reinforced tensile layer that enhances the tensile strength of the planar base fabric 1. Silicon carbide abrasive 4 is sprayed onto the surface of the tensile-strength reinforcing layer; Polyurethane 5 is sprayed onto the surface of the aramid reinforced mesh 2, which does not have steel wire mesh 3, to form an anti-slip layer for contact with external rotating mechanisms, such as drive wheels.

[0018] Example 2, a silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products as described in Example 1, wherein the material of the flat base cloth 1 is polyester fiberglass cloth.

[0019] In Example 2, the planar base fabric 1 is made of polyester fiberglass cloth. Polyester fiberglass cloth has good tensile strength and flexibility, which makes it easy for sandpaper to fit into irregular curved surfaces for sanding, while the material cost is low.

[0020] Example 3, a silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products as described in Example 1, wherein the diamond mesh number of the flat base cloth 1 is 10-20 mesh.

[0021] In Example 3, the rhombic mesh of the planar base fabric 1 is 10-20 mesh. This mesh structure ensures that the planar base fabric 1 has enough open space, allowing the adhesive to fully penetrate and form a certain mechanical anchoring effect when the silicon carbide abrasive 4 is bonded to the reinforcing tensile layer with phenolic resin. It also ensures that the planar base fabric 1 itself has high strength and stability.

[0022] Example 4: The silicon carbide coated abrasive cloth suitable for polishing stone and glass fiber products described in Example 1 has a mesh size of aramid reinforced mesh 2 that is smaller than the rhomboid mesh size of the planar base cloth 1. The specific mesh size value can be selected according to the usage requirements.

[0023] Example 5: The silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products described in Example 1, wherein the wire mesh 3 is a copper-plated wire mesh with a wire diameter of 0.1-0.3 mm, the specific diameter value of which can be selected according to the usage requirements.

[0024] Example 6: The silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products described in Example 1 has an anti-slip layer thickness of 0.2-0.5mm, and the specific thickness value can be selected according to the usage requirements.

[0025] The process of manufacturing and using silicon carbide coated abrasive cloth suitable for polishing stone and fiberglass products in Example 1 is as follows: Manufacturing process: A flat base fabric 1 woven into a diamond-shaped mesh is provided, preferably made of polyester or nylon, with a mesh count controlled between 10-20 meshes. Aramid reinforcing mesh 2 is then placed on the front and back surfaces of the flat base fabric 1, respectively. The aramid reinforcing mesh 2 is then bonded to the upper and lower surfaces of the flat base fabric 1 by hot pressing. Next, a steel wire mesh 3 is placed on one surface of the substrate with the bonded aramid reinforcing mesh 2. The nodes of the steel wire mesh 3 are then spot-welded to the underlying aramid reinforcing mesh 2 to form the reinforcing tensile layer. A layer of high-temperature resistant resin adhesive, such as phenolic resin or epoxy resin, is then coated on the side of the aramid reinforcing mesh 2 with the steel wire mesh 3. Before the resin adhesive cures, silicon carbide abrasive is applied using electrostatic or gravity sand-planting methods. 4. Spray and vertically embed the adhesive evenly. After the sand is planted, cover the surface of the abrasive layer with the same resin adhesive to better cover and fix the abrasive. Finally, coat the surface of the aramid reinforcing mesh 2 without the wire mesh 3 with a layer of polyurethane 5 coating evenly by scraping or spraying. The thickness is controlled at 0.2-0.5mm. In addition, in order to enhance its anti-slip effect, the surface of the coating can be pressed with an embossing roller to create a textured surface before the coating is cured. Then, put the prepared silicon carbide coated abrasive cloth semi-finished product into the oven for heating and curing so that the resin adhesive and polyurethane 5 coating can be fully cross-linked and cured, and firmly bonded to each layer of the substrate. After curing, the final specifications of the abrasive cloth product are produced through cooling, cutting, stamping, inspection and other processes. During use, simply attach the side of the silicon carbide-coated abrasive cloth with the polyurethane coating to the power output end of the external rotary mechanism, such as the outer circumference of the drive wheel / roller.
