preparation example Construction

[0027] The preparation method of the above-mentioned foam hand wipe block specifically includes the following steps.

[0028] A. Add abrasives, light-curing adhesives, photoinitiators and auxiliary agents to the container in proportion, and disperse with high stirring and avoiding light. The stirring speed is 700-1500rpm and the dispersion time is 2-8h to form a slurry.

[0029] B. Apply the disperse-qualified slurry to the mold with the three-dimensional structure of the abrasive block by roller coating, then coat the abrasive layer base material on the surface of the mold, and irradiate the abrasive layer base material with ultraviolet light when passing through, so that the slurry Cured and transferred to a substrate to form a repeating modular structure.

[0030] C. The preliminarily formed module is heated and cured at 80-120° C. for 12-36 hours to obtain a three-dimensional structure grinding mechanism.

[0031] D. Press the polishing mechanism prepared in step C with t...

Embodiment 1

[0033] A foam hand-wiping block, comprising a foam base 1, the top surface of the foam base is fixedly connected with a polishing mechanism through an adhesive layer 2, and the polishing mechanism includes an abrasive layer 3 adhered to the adhesive layer and cured on the adhesive layer 3. The three-dimensional abrasive block 4 on the top surface of the abrasive layer. The structure of this embodiment is as follows figure 1 As shown in the figure, the abrasive block is a cylindrical structure, and the foam matrix is ​​a square structure; of course, the shape of the abrasive block can also be a pyramid, square, raindrop, triangle or irregular three-dimensional structure. When in use, it can be set according to the specific requirements of the object to be polished.

[0034] One side wall of the foam base 1 is provided with a groove 5, and the base material of the abrasive layer is polyester cotton.

[0035] The abrasive block is prepared from the following components in parts...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 lies in the shape and structure of the grinding block, the formula ratio of the abrasive block, and the parameters of each process step in the preparation method.

[0043] In this embodiment, the foam base is in a concave arc shape, and the base material of the abrasive layer is PET. The abrasive block is prepared from the following components in parts by weight: 65 parts of abrasive, 55 parts of light-curing adhesive, 5 parts of photoinitiator, and 5 parts of auxiliary; wherein, the abrasive is alumina, and the particle size range is 10- 80μm; the light-curing adhesive is epoxy acrylic resin adhesive, the photoinitiator is 819 photoinitiator, and the auxiliary agents include anti-settling agent, silane coupling agent and heat dissipation agent.

[0044] The preparation method of the above-mentioned foam hand wipe block specifically includes the following steps.

[0045] A. Add abrasives, light-curing adhesives, p...

Abstract

The invention discloses a foam hand rubbing block and a preparation method thereof. The hand rubbing block comprises a foam base body which is convenient to hold by hand, the top end surface of the foam base body is fixedly connected with a grinding mechanism for achieving a grinding operationby a bonding adhesive layer, and thegrinding mechanism includes an abrasive layer adhered to the bonding adhesive layer and a three-dimensional abrasive block solidified on the top end surface of the abrasive layer; the preparation method includes the steps of mixing materials, forming a module, curingandpressing. According to the foam hand rubbing block prepared by the method, abrasive materials have a wide range ofgrain sizes and can be made according to the processing requirements of a workpiece,a large-grained abrasive block has high grinding force and processing efficiency, a small-grained abrasive block has a finemachined surface, abrasive blocks of different grain sizes can be used aloneor in combination, and the advantages of high processing efficiency and good processing effect are also achieved.

Description

technical field [0001] The invention relates to the technical field of workpiece grinding, in particular to a hand rubbing block for grinding hard workpieces such as metal and a preparation method thereof. Background technique [0002] In workpieces made of materials such as metal, ceramics, glass, stone, wood, composite materials, semiconductors, etc., there are often problems of inconvenient processing of workpiece edges and inconvenient maintenance of later products. Operators usually use hand-wiping blocks to operate the workpiece. , The hand-wiping block is small in size, easy to operate, can partially repair the workpiece, and has a wide range of use. At present, the common hand wipe blocks on the market include electroplated diamond hand wipe blocks and electrostatic sand planting hand wipe blocks, which are made of electroplated diamond emery cloth or resin gauze pasted on the foam substrate. However, due to the characteristics of electroplating process and electrost...
