Abstract

The invention discloses a multifunctional PCD diamond grinding wheel and a preparation method thereof, and belongs to the technical field of grinding tools. The grinding wheel comprises a disc-shaped base body and tool bits, the tool bits comprise PCD grinding blocks and diamond tool bits, the diamond tool bits are evenly distributed on the lower end face of the disc-shaped base body, and one to two PCD grinding blocks are arranged between every two diamond tool bits. The diamond tool bit comprises the following raw materials: 26 to 36 parts of copper, 32 to 42 parts of iron, 4 to 12 parts of nickel, 13 to 25 parts of cobalt, 6 to 13 parts of tin, 1.1 to 2.3 parts of phosphorus or carbon, 0.9 to 1.6 parts of liquid paraffin and 1.0 to 2.2 parts of diamond. The PCD grinding block and the diamond tool bit are jointly welded to the grinding head base body, the grinding wheel can grind epoxy resin on the surface of an epoxy floor layer firstly through the optimized design of raw materials of the tool bit, after PCD grinding is completed, the arrow-shaped diamond tool bit can continue to be used for grinding a concrete surface layer, and the grinding wheel has excellent heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a multifunctional PCD diamond grinding wheel and a preparation method thereof. Background technique [0002] Epoxy flooring is constructed by epoxy sealing primer, so that epoxy can penetrate and seal the capillary pores of concrete, and improve the bonding force with the foundation concrete. The cured primer material closes the concrete capillary pores; The construction of the oxygen putty layer is mainly to fill up the holes that cannot be filled after the construction of the primer. [0003] In the current environment of rapid industrial development, there are more and more epoxy floor pavements, and repeated repairs require the use of grinding wheels for grinding. Generally, diamond grinding wheels are used for grinding concrete. However, since the surface of the epoxy floor is an epoxy layer, and the diamond cutter head is easy to be blocked when grinding due to its ...
