Description

Technical Field

[0001] This utility model relates to the field of coated abrasive technology, and in particular to a cloth-paper composite coated abrasive. Background Technology

[0002] Coated abrasives are abrasives made by adhering abrasive to a flexible substrate (such as a composite substrate like cloth or paper) with an adhesive. They are also known as flexible abrasives. Coated abrasives come in sheet-like (rectangular), disc-like, ring-like, and other special shapes. The main types are abrasive cloth (paper) and abrasive belts. They are often used mechanically or manually and are widely used for grinding, polishing, and sanding non-metallic materials such as metals, wood, ceramics, plastics, leather, rubber, and paint putty.

[0003] A coated abrasive tool with publication number CN216883440U includes: a substrate; and an abrasive section disposed on the surface of the substrate. The abrasive section comprises: multiple spaced, wavy abrasive strips, with gaps between adjacent abrasive strips forming chip removal grooves. This invention utilizes multiple wavy abrasive strips on the substrate to create a three-dimensional, multi-layered abrasive section on the substrate surface. This ensures that during product polishing, as the abrasive strips are continuously consumed, the contact area between the abrasive strips and the product remains constant, improving the polishing effect and extending the service life.

[0004] However, existing coated abrasives still have the following drawbacks when used: The existing technology involves setting multiple abrasive strips spaced apart on the surface of the substrate to facilitate polishing of the product. However, in actual use, the above operation does not have a protective function, making the substrate susceptible to external factors (such as moisture, corrosive substances, etc.), which can lead to deformation of the substrate and affect subsequent polishing operations. Utility Model Content

[0005] The purpose of this invention is to provide a cloth-paper composite coated abrasive to solve the problem mentioned in the background art that the existing cloth-paper composite coated abrasive does not have a protective function during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cloth-paper composite coated abrasive, comprising a base layer and an abrasive layer, wherein the abrasive layer is disposed on the top of the base layer;

[0007] A protective mechanism is provided on the outer side of the base layer, and a heat insulation mechanism is provided at the top of the protective mechanism. The top of the heat insulation mechanism is fixedly connected to the abrasive layer, and a guide groove is uniformly opened at the top of the abrasive layer.

[0008] Furthermore, the protective mechanism includes a protective layer, which is disposed on the outside of the base layer. A carbon fiber layer is disposed on the outside of the protective layer, and a protective layer is uniformly coated on the outside of the carbon fiber layer.

[0009] Furthermore, the protective layer is disposed between the carbon fiber layer and the base layer, and the protective layer is made of phenolic resin.

[0010] Furthermore, the protective layer has a rectangular cross-section, and the material of the protective layer is a ceramic coating.

[0011] Furthermore, the heat insulation mechanism includes a graphene film layer, which is disposed at the bottom end of the abrasive layer. The bottom end of the graphene film layer is adhered to a heat insulation layer by an adhesive, and the bottom end of the heat insulation layer is adhered to a copper foil layer by an adhesive.

[0012] Furthermore, the heat insulation layer has a rectangular cross-section, is disposed between the graphene film layer and the copper foil layer, and is made of ceramic fiber.

[0013] Furthermore, multiple guide channels are provided, each with a rectangular cross-section, and the multiple guide channels are distributed at equal intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cloth-paper composite coated abrasive not only has anti-slip function, but also heat insulation function;

[0015] 1. The protective layer provides excellent water and solvent resistance, preventing the base material from absorbing moisture and deforming in humid or oily environments. This avoids uneven abrasive layer distribution caused by base material expansion. The carbon fiber layer provides conductivity, forming a conductive network on its surface to promptly conduct static charges generated during grinding to the ground, preventing dust accumulation and clogging of the abrasive layer. Furthermore, the carbon fiber layer prevents the penetration of oxygen and corrosive substances in the grinding fluid, avoiding oxidative degradation of the base material. These features extend the service life of the base material, thereby reducing replacement costs.

[0016] 2. By setting a graphene film layer, longitudinal heat insulation and lateral heat dissipation can be achieved during use. Furthermore, the heat insulation effect can be further enhanced by the heat insulation layer and copper foil layer, thereby preventing heat transfer to the base layer. Through the above operations, the impact of heat on the base layer is reduced, thereby improving its practicality.

[0017] 3. By setting up a guide trough, the waste generated during product grinding will fall into the guide trough and be discharged through it, thereby avoiding the accumulation of waste and reducing the contact area between waste and product, preventing secondary scratches on the product, and improving the grinding effect.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] Example 1: To address the lack of protective functionality in existing technologies, the following technical solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a cloth-paper composite coated abrasive includes a base layer 1 and an abrasive layer 3. The abrasive layer 3 is disposed at the top of the base layer 1, and a protective mechanism 2 is disposed on the outside of the base layer 1. The protective mechanism 2 includes a protective layer 201, which is disposed on the outside of the base layer 1. A carbon fiber layer 202 is disposed on the outside of the protective layer 201, and a protective layer 203 is uniformly coated on the outside of the carbon fiber layer 202. The protective layer 201 is disposed between the carbon fiber layer 202 and the base layer 1. The protective layer 201 is made of phenolic resin, and the protective layer 203 has a rectangular cross-section and is made of ceramic coating material.

[0028] In this embodiment, a protective layer 201 is provided. The protective layer 201 is made of phenolic resin. After curing, this material has a three-dimensional network structure with small molecular gaps, making it difficult for water molecules to penetrate, thus giving it good waterproof performance. This prevents the base layer 1 from absorbing moisture and deforming in humid or oily environments. At the same time, a carbon fiber layer 202 is provided. Due to its unique graphitized structure, the carbon fiber layer 202 has a large interlayer spacing and low electron hopping conduction efficiency, giving it conductivity between that of metals and semiconductors. This allows the static charge generated during grinding to be promptly conducted to the ground. Furthermore, a protective layer 203 is provided. The protective layer 203 is made of ceramic coating material. Due to its high density, chemical inertness, and low permeability, this material can effectively block oxygen and corrosive substances in the grinding fluid, such as acidic / alkaline media and chloride ions, significantly extending the life of the base layer 1, such as metal or composite materials. Through the above operations, the base layer 1 maintains stable performance under complex working conditions such as high temperature, high humidity, and high load, thereby improving its service life.

[0029] Example 2 differs from Example 1 in that it also has a heat insulation function during use. Therefore, the following technical solution is disclosed. Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the top of the protective mechanism 2 is provided with a heat insulation mechanism 5. The heat insulation mechanism 5 includes a graphene film layer 501, which is disposed at the bottom of the abrasive layer 3. A heat insulation layer 502 is adhered to the bottom of the graphene film layer 501 by an adhesive, and a copper foil layer 503 is adhered to the bottom of the heat insulation layer 502 by an adhesive. The heat insulation layer 502 has a rectangular cross-section and is disposed between the graphene film layer 501 and the copper foil layer 503. The heat insulation layer 502 is made of ceramic fiber. The top of the heat insulation mechanism 5 is fixedly connected to the abrasive layer 3. A guide groove 4 is evenly provided on the top of the abrasive layer 3. Multiple guide grooves 4 are provided, each with a rectangular cross-section, and are evenly distributed.

[0030] In this embodiment, by providing a graphene film layer 501, which is ultra-thin and flexible, the graphene film layer 501 not only does not affect the bending performance of the abrasive layer 3, but also achieves longitudinal heat insulation and lateral heat dissipation. Simultaneously, by providing a heat insulation layer 502 made of ceramic fiber, the heat insulation layer 502 significantly reduces heat transfer to the base layer 1, effectively protecting it and reducing its impact. Furthermore, by providing a copper foil layer 503, the heat insulation layer 502's special properties allow for rapid lateral heat conduction, preventing localized high temperatures and thus preventing carbonization or deformation of the base layer 1. Through these operations, the heat generated during grinding is isolated, reducing its impact on the base layer 1 and improving its practicality.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
