Description

Technical Field

[0001] The utility model relates to a flocking fabric for grinding and polishing, and belongs to the technical field of flocking fabrics. Background Art

[0002] Flocking fabrics can usually be used for polishing alloy metals, non-metals, electronic components, polymers, ceramics, heat-treated surfaces, and metal metallographic sections. However, flocking fabrics are usually flocked on one side of the base surface, and different fiber materials are suitable for different polishing materials. The flocking fabric needs to be replaced after polishing, which will cause waste. If flocking is performed on both sides, the use of the base layer will be reduced after one side is used and then the other side is used, which will avoid waste. How to prepare a flocking fabric for polishing that avoids waste of the base layer has become a problem to be solved. Utility Model Content

[0003] The utility model aims to provide a flocking fabric for grinding and polishing, in which different fibers are flocked on two layers of a base layer to adapt to different grinding and polishing materials and avoid waste of base layer resin.

[0005] The utility model relates to a flocking fabric for grinding and polishing, comprising a base layer, a first flock layer being fixedly adhered to one side of the base layer through a first flocking adhesive layer, and a second flock layer being fixedly adhered to the other side of the base layer through a second flocking adhesive layer;

[0006] The fiber used in the first flock layer is caterpillar cross-section nylon 66 fiber with a fineness of 1-2D, and the length exposed from the first flocking glue layer is 0.4-0.6mm;

[0007] The fibers used in the second flock layer are descaled wool fibers with a fineness of 12-23 μm, and the length of the fibers exposed from the second flocking adhesive layer is 1-2 mm.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the cross section of the caterpillar-section nylon fiber includes a straight-line fiber body and protrusions symmetrically arranged on both sides of the fiber body.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the number of the protrusions is 4.

[0010] On the basis of the above solution and as a preferred solution of the above solution: the first flocking glue layer and the second flocking glue layer are made of water-resistant and alcohol-resistant flocking glue.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the base layer includes two ABS resin layers, and a planar three-dimensional fabric layer sandwiched between the two ABS resin layers 11.

[0012] The beneficial effect of the utility model is that the flocked fabric for grinding and polishing involved in the utility model has wool fibers and nylon 66 fibers flocked on both sides of the base layer, so that the polishing cloth prepared by the flocked fabric can adapt to different polishing materials, and one side can be used before the other side, which can avoid the waste of base layer resin.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] Combination Figure 1 and Figure 2 The present embodiment is described in detail. The flocking fabric for grinding and polishing involved in the present embodiment is characterized in that it comprises a base layer 1, a first flock layer 3 is fixedly adhered to one side of the base layer 1 through a first flocking adhesive layer 2, and a second flock layer 5 is fixedly adhered to the other side of the base layer 1 through a second flocking adhesive layer 4.

[0023] The fiber used in the first flock layer 3 is caterpillar cross-section nylon 66 fiber with a fineness of 1-2D, and the length exposed from the first flocking adhesive layer 2 is 0.4-0.6mm. In this embodiment, the caterpillar cross-section nylon 66 fiber with a fineness of 1.67D is selected, and the length exposed from the first flocking adhesive layer 2 is 0.5mm.

[0024] Furthermore, the cross section of the caterpillar-section nylon 66 fiber includes a straight-line fiber body 31 and protrusions 32 symmetrically arranged on both sides of the fiber body 31. The cross-sectional shape is a slender flat structure, which is very similar to the shape of a caterpillar and has good uprightness, so that the fiber can stand up quickly after bending. Even if it bends during transportation or use, it can quickly restore the upright state. Furthermore, the number of the protrusions 32 is 4.

[0025] The fiber used in the second flock layer 5 is descaled wool fiber with a fineness of 12-23 μm, and the length of the fiber exposed from the second flocking adhesive layer 4 is 1-2 mm, and is 1.5 mm in this embodiment. First, the wool yarn is descaled, and then the wool fiber is cut into the required length, and the cut wool is electrostatically treated, and then the wool fiber is flocked on the second flocking adhesive layer 4 through an electrostatic flocking device, and then cured and bonded.

[0026] Furthermore, the first flocking glue layer 2 and the second flocking glue layer 4 use water-resistant and alcohol-resistant flocking glue. Selecting water-resistant and alcohol-resistant flocking glue can make the flock layer and the flock layer more firmly bonded to the flock glue layer when the flock fabric is used for polishing. When in use, the bonding strength of the flock layer will not be reduced due to moisture absorption.

[0027] Furthermore, in this embodiment, the base layer 1 is ABS resin.

[0028] Embodiment 2

[0029] Combination Figure 3 , this embodiment is described in detail. The flocked fabric for grinding and polishing involved in this embodiment is different from that of the first embodiment in that: the base layer 1 includes two ABS resin layers 11, and a planar three-dimensional fabric layer 12 sandwiched between the two ABS resin layers 11. The planar three-dimensional fabric used in the planar three-dimensional fabric layer 12 is made of three groups of yarns interwoven at 60°. The fabric composed of three groups of yarns has isotropic mechanical properties. No matter in which direction the fabric is subjected to force, its deformation presents a fairly uniform equivalent strain, which overcomes the large difference in shear resistance and tensile resistance of the two-dimensional fabric at a 45° oblique direction, thereby making the flocked fabric for grinding and polishing involved in this embodiment isotropic.

[0030] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
