DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0018] like Figure 1As shown, a double-sided sanding cloth that can complete rough grinding and polishing in one step includes a composite base cloth 1, a base plate 2 and a sanding particle layer 3. The base plate 2 is bonded by a polyethylene polypropylene layer 21, a polypropylene layer 22 and an adhesive layer 23 in sequence by waterproof adhesive. The polyethylene polypropylene layer 21 is a waterproof material, which can prevent the composite base cloth 1 from being deformed due to contact with water, thereby increasing the service life of the sanding cloth. The polypropylene layer 22 is a semi-crystalline thermoplastic plastic with high impact resistance, strong mechanical properties, resistance to corrosion by multiple organic solvents and acids and alkalis, thereby increasing the hardness of the double-sided sanding cloth. The adhesive layer 23 bonds the sanding particles.

[0019] According to a specific embodiment of the present invention, the substrate 2 is composed of a polyethylene polypropylene layer 21, a polypropylene layer 22 and an adhesive layer 23 which are sequentially bonded by waterproof adhesive, so that the bonding is more firm and the service life of the double-sided frosted cloth is increased.

[0020] like Figure 1 As shown, a first substrate 4 and a second substrate 5 are arranged on the upper surface and the lower surface of the composite base cloth 1, and the polyethylene polypropylene layers 21 of the first substrate 4 and the second substrate 5 are bonded to the upper surface and the lower surface of the composite base cloth 1 by an adhesive, and a first frosted particle layer 6 and a second frosted particle layer 7 are arranged on the adhesive layer of the first substrate 4 and the adhesive layer of the second substrate 5, and the size of the frosted particles of the first frosted particle layer 6 is larger than the size of the frosted particles of the second frosted particle layer 7.

[0021] According to a specific embodiment of the present invention, during the grinding process, the object needs to be roughly ground first and then finely ground. The double-sided sanding cloth can improve work efficiency, reduce the time of finding sanding cloth and changing grinding tools, and improve work efficiency.

[0022] like Figure 1 As shown, the adhesive layer 23 is provided with a plurality of circular grooves, one end of the frosted particles is evenly embedded in the circular grooves, and the other end of the frosted particles is exposed from the circular grooves.

[0023] According to a specific embodiment of the present invention, a flexible double-sided sanding cloth can be made into a coated abrasive tool such as a grinding flap wheel, a sanding disc, etc. with a double-sided grinding effect, which can be installed on a corresponding grinder and operated at high speed. Under a certain pressure, the double-sided sanding cloth is brought into contact with the surface of the workpiece to realize the entire process of double-sided grinding.

[0024] like Figure 1 As shown, the substrate 2 is provided with a plurality of through holes 11 penetrating the upper and lower surfaces of the substrate, and the plurality of through holes are evenly distributed along the substrate. During the rotation of the double-sided sanding cloth, dust gathers on the surface of the substrate 2 and is discharged through the through holes, thereby preventing dust from being blocked on the surface of the sanding cloth. At the same time, the heat generated by the friction between the sanding particles and the workpiece surface can be diffused through the through holes, thereby playing a heat dissipation role, extending the service life of the double-sided sanding cloth, and ensuring the grinding quality of the workpiece surface.

[0025] like Figure 1As shown, the adhesive is epoxy resin glue, and the polyethylene polypropylene layer 21 of the first substrate 4 and the second substrate 5 is bonded to the upper surface and the lower surface of the composite base cloth 1 through the adhesive, and the bonding is firm, thereby improving the bonding strength of the emery cloth abrasive.

[0026] The abrasive particles are ceramic microcrystalline deposited abrasives, diamond, silicon carbide, brown corundum, black corundum or white corundum abrasives, which can adapt to grinding objects of different materials and meet different precision requirements.

[0027] The composite base fabric 1 is made of cotton, blended, polyester or linen, has certain flexibility, and reduces production costs.

[0028] The frosted particles are bonded to the circular grooves inside the adhesive layer by nano-silicon waterproof adhesive. The nano-silicon waterproof adhesive has good bonding performance, which prevents the frosted particles from falling off during the grinding process and increases the service life of the double-sided frosted cloth.

[0029] The waterproof glue is PVC glue, which has good alkali resistance and corrosion resistance, making the double-sided frosted cloth have good alkali resistance and corrosion resistance.

[0030] The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or change made by a person skilled in the art on the basis of the present invention is within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
