Problems solved by technology

[0002] At present, the method for polishing the surfaces of materials such as stone, glass, ceramics, and metals is: use a cloth wheel or a pickle cloth that does not contain abrasive polishing materials to perform polishing operations. During the polishing operation, it is necessary to add polishing powder or The polishing paste is placed on the surface of the material to be polished. In this way, the polishing powder or polishing paste is easily thrown out, which causes a serious waste of polishing materials, and the polishing is slow, and the polishing efficiency is low. In addition, the polishing cloth is quickly worn out. High cost of polishing
[0003] For rough grinding and fine grinding of materials such as stone, glass, ceramics, concrete, etc., metal bonded diamond grinding discs or resin bonded diamond grinding discs are generally used for processing, and the specifications and sizes of these two types of grinding discs are difficult to enlarge. , usually the diameter is less than 200mm, and the grinding efficiency is relatively low
Moreover, the softness of the grinding disc is not good enough, and it cannot grind and polish complex shapes such as uneven surfaces and corner surfaces, and the polishing performance is relatively poor.
[0004] The utility model patent with the notification number CN2219181 relates to a flexible metal-bonded abrasive disc for grinding and polishing metal or non-metallic surfaces. The efficiency is not high. The utility model combines the flexible metal sheet with frosting to make a horn shape, and several unconnected strip metal sheets are made from the mouth of the horn to the bottom of the horn. It has good durability, high efficiency and is not easy to wear during use. , especially suitable for grinding and polishing of various high-precision, high-gloss surfaces and molding surfaces

Embodiment 1

[0035] This embodiment is a manufacturing method for making a No. 1500 polishing sheet according to the particle size requirements, and this manufacturing method corresponds to the first technical solution of the present invention.

[0036] 1) Cut the non-woven fabric according to the specifications, and then press it on a hot press at a temperature of 150°C and a pressing time of 8 minutes, and take it out for use;

[0037] 2) preparation of polishing abrasive material glue: by mass percentage, W7 (or W10) diamond micropowder 20%; Epoxy resin glue 50%, other materials 30%; By mass percentage, each material in described other materials accounts for polishing grinding The percentages of the total mass of the material glue are: W5 silicon carbide 10%, aluminum oxide 5%, zinc oxide 10%, cryolite 5%; each raw material is weighed according to the above ratio, and the powder is first mixed evenly, and then added to the glue Stir evenly in the liquid, if the glue is thicker, you can ...

Embodiment 2

[0041] This embodiment is a manufacturing method for making a No. 100 polishing sheet according to the particle size requirement, and this manufacturing method corresponds to the second technical solution of the present invention.

[0042] 1) Prepare the polyester fiber material;

[0043] 2) preparation of polishing abrasive material glue: by mass percentage, 80 / 100 diamond powder 10%; polyurethane glue 50%, other materials 40%; each material in the other materials accounts for the percentage of polishing abrasive material glue total mass respectively For: W63 silicon carbide 20%; magnesium oxide 10%, silicon dioxide 7%, graphite 3%. Weigh each raw material according to the above ratio, wherein the powder is firstly mixed evenly and then added to the glue and stirred evenly. If the glue is thicker, a proper amount of diluent can be added to prepare it to obtain a polishing abrasive glue, which is ready for use;

[0044] 3) Weigh the polishing abrasive material glue and the po...

Embodiment 3

[0047] This embodiment is a manufacturing method for making a marble (or granite) polishing sheet, and the manufacturing method corresponds to the second technical solution of the present invention.

[0048] 1) Prepare the polypropylene fiber material;

[0049]2) preparation of polishing abrasive material glue: by mass percentage, ultrafine diamond micropowder 5%, polyvinyl alcohol glue 50%, other materials 45%, described other materials are marble (or granite) polishing powder); according to the above Proportionally weigh each raw material, mix the powder evenly and then add it to the glue solution and stir evenly to obtain a polishing abrasive material glue solution for use;

[0050] 3) Weigh the polishing abrasive material glue and the polypropylene fiber material according to the mass ratio of 75:25 and mix them evenly;

[0051] 4) Then pour into the mold and heat press to solidify at a temperature of 130° C. for 30 minutes. After demolding, it is made into a marble (or g...

Abstract

Disclosed are a flexible polishing sheet and a production method thereof. The flexible polishing sheet is high in grinding efficiency, fast in polishing and brightening rate, long in service life and low in cost, and is provided with a flexible base layer and a polishing layer coated on the surface of the flexible base layer, or the flexible polishing sheet is made of fibers and polishing abrasive material by mixing and hot pressing, and the mass ratio of the fibers to the polishing abrasive material is (20-40):(80-60). The flexible polishing sheet can be used for directly polishing a material with no extra polishing powder or polishing paste to be added on the surface of the material, so that great loss of polishing materials is avoided, cost is saved, brightening speed is fast during polishing, efficiency is high, and the flexible polishing sheet is resistant to wearing and long in service life. The flexible polishing sheet can be easily made into large-sized flexible polishing products, the polishing area is enlarged evidently, and the polishing efficiency is improved. The flexible polishing sheet can also be made into highly flexible polishing products of different granularities from thickness to fineness, and can be used for polishing uneven surfaces, edge and corner surfaces and the like step by step.
