Problems solved by technology

The dry grinding method does not need to add cooling water, which solves the environmental protection problem of sewage discharge and pollutes the environment (the dust generated by dry grinding is easier to collect and solve), and the processing and operation are convenient, especially in the environment where it is inconvenient to add water. For severe water shortage Countries or regions, such as desert areas and high mountains in the Middle East, have more advantages in dry grinding, but dry grinding (especially long-term dry grinding) requires high temperature resistance of the grinding disc. If the grinding disc Insufficient high temperature resistance will cause smoking and burning, discoloration and adhesion residue on the surface of the grinding disc and the material to be ground during the grinding process, resu

Embodiment 1

[0027] see figure 1 , The diamond dry grinding disc of the present invention is provided with an abrasive layer 1 and a connecting piece 2, the connecting piece 2 is bonded to the abrasive layer 1, and the connecting piece 2 is externally connected to a power transmission member. The thickness of the abrasive layer of the diamond dry grinding disc can be determined according to actual needs. Weigh 50g of high-temperature and oxygen-resistant resin, 20g of diamond particles, 20g of silicon carbide, and 10g of zinc oxide, and put them into a mixing tank to mix and stir evenly. Inject into a mold with a certain geometric shape, put in the nylon hook layer carrier accessories, close the mold and heat it to 100°C for 40 minutes, take it out and demould, and heat the molded abrasive layer in an oven for post-curing at a temperature of 120°C , time 4h, take out the cured abrasive layer and connect with heat-resistant polyurethane glue for bonding, so as to make a high-temperature re...

Embodiment 2

[0029] Similar to Example 1. Weigh 40g of high-temperature-resistant unsaturated polyester resin, 25g of diamond particles, 15g of tungsten carbide, 6g of aluminum powder, and 14g of aluminum oxide, put them into a mixing tank and mix them evenly, inject them into a mold with a certain geometric shape, and put them into a nylon hook layer carrier For accessories, heat the mold to 130°C for 20 minutes, remove the mold, put the formed abrasive layer into the oven to heat for post-curing, the temperature is 140°C, and take 1h, take out the cured abrasive layer and the connector with a durable Hot universal glue is used for bonding and bonding, so as to make high temperature resistant diamond dry grinding discs.

Embodiment 3

[0031] Similar to Example 1. Weigh 25g of high-temperature-resistant melamine resin, 15g of phenolic resin, 15g of diamond particles, 10g of boron nitride, 20g of silicon carbide, and 15g of titanium oxide, put them into a mixing tank and mix them evenly, inject them into a mold with a certain geometric shape, and put them into a nylon hook For layer carrier accessories, heat the mold to 120°C for 25 minutes, take out the mold, and put the formed abrasive layer into the oven for post-curing. The temperature is 130°C, and the time is 3h. Take out the cured abrasive layer and connecting parts Bonding and bonding with heat-resistant epoxy resin glue to make high-temperature resistant diamond dry grinding discs.

Abstract

The invention relates to a diamond dry grinding disc and a manufacturing method thereof, relating to the diamond dry grinding disc. The invention provides the diamond dry grinding disc with large grinding amount, long grinding time, good high-temperature resistance and good wearing resistance and the manufacturing method thereof. The diamond dry grinding disc is provided with a grinding material layer and a connecting piece, wherein the connecting piece is fixedly connected with the grinding aid layer; the connecting piece is externally connected with a power transmission piece; and the grinding material layer comprises the following components in parts by weight: 30% to 50% of high-temperature resistant resin, 15% to 30% of diamond particles and 30% to 50% of wearing resistant radiating additive. The raw materials are weighed according to formula percentage, and are uniformly mixed. The uniformly mixed raw materials are poured into a mould for matching mould. The raw materials are heated in an oven after matching mould and are demoulded after solidifying to obtain a molding green body, the molding green body is heated for solidifying in the oven to obtain the grinding aid layer, and the grinding aid layer is spliced with the connecting piece to obtain a finished product.

Description

technical field [0001] The invention relates to a diamond grinding disc, in particular to a diamond dry grinding disc mainly used for grinding non-metallic hard and brittle materials such as cement floor, stone, glass and ceramics and a manufacturing method thereof. Background technique [0002] There are two types of grinding methods for cement floor, stone, glass, ceramics and other non-metal hard and brittle materials, wet grinding and dry grinding. The wet grinding method has lower requirements on the high temperature resistance of the grinding discs, which can be met by ordinary grinding discs, but requires a large amount of cooling water and produces a large amount of sewage, which is not environmentally friendly. The dry grinding method does not need to add cooling water, which solves the environmental protection problem of sewage discharge and pollutes the environment (the dust generated by dry grinding is easier to collect and solve), and the processing and operatio...
