The base is the main supporting part of the bonded cutter head.

[0003] Existing diamond saw blades have poor impact toughness performance and low wear resistance. It is difficult to achieve coordinated improvement in impact toughness, wear resistance and thermal conductivity. In addition, the products have poor resistance to salt spray, water humidity and cold and heat stability, which limits the use efficiency of the products. Summary of the invention

[0027] The boron nitride in the coordination treatment agent is treated with sodium dodecylbenzene sulfonate solution, so that it can better blend nano-silica sol and yttrium oxide, and then through the co-formulation of sodium carboxymethyl cellulose and sodium silicate solution, the coordination treatment agent system formed is based on boron nitride and doped with the rare earth property of yttrium, which can better reinforce and coordinate the coordination treatment agent with the modified additive, thereby further improving the performance of the product.

[0028] Preferably, the mass fraction of the sodium silicate solution is 3-5%.

After the molding is completed, demolding is performed and then sintered at 820-850℃ for 1h to obtain a diamond segment. Finally, the diamond segment and the main substrate are welded together to obtain a diamond saw blade.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

At the same time, the flaky nano-alumina treatment was not used in the preparation of the modified adjuster, and carbon fiber and calcite were not added to the modified lanthanum liquid. The performance of the product showed a trend of deterioration. In addition, no lanthanum chloride solution was added to the modified lanthanum liquid, and no dopamine hydrochloride solution was added to the modified lanthanum liquid. The performance of the product showed a trend of deterioration to varying degrees. The modified adjuster obtained by improving the flaky nano-alumina with the modified lanthanum liquid obtained by combining carbon fiber, calcite and specific raw materials has the most significant product performance effect. Only the performance effect of the product prepared by using the specific raw materials of the present invention is the most significant. Other methods are not as obvious as the effect of the present invention.

[0164] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0165] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
