Abstract

The invention discloses a water mill for stone machining and a preparation method thereof. The water mill is prepared through black silicon carbide, silica, polyethylene glycol, epoxy resins, methyl ethyl ketone peroxide, cobalt iso-octoate and magnesium sulfate. The method comprises placing the polyethylene glycol and the epoxy resins in a reaction still to be heated and stirred evenly; putting the black silicon carbide, silica and the magnesium sulfate in a mixer to be stirred and mixed evenly; putting the evenly stirred mixtures in the mixer to be stirred evenly, adding methyl ethyl ketone peroxide and cobalt iso-octoate in the mixtures to be heated and stirred evenly to be discharged to obtain a mixed material; and putting the mixed material in a mould, and molding and drying the material naturally under the normal pressure and temperature to obtain the product water mill. The water mill prepared through the method has a higher grinding effect, surface smoothness and brightness than an ordinary grinding head, and ideal effects of users can be achieved without wool wheel polishing.

Description

technical field [0001] The invention relates to a grinding head for stone processing, in particular to a water grinding wheel for stone processing and a preparation method thereof. Background technique [0002] In real life, many products need to be polished because of surface accuracy requirements or aesthetic considerations. The main method is to move a high-speed rotating grinding head on the surface to be polished to polish the surface. Grinding head is a general term for a small grinding tool with a handle, which is used in electric grinders, hanging grinders, electric hand drills, etc. There are many types of grinding heads, mainly ceramic grinding heads, rubber grinding heads, diamond grinding heads, emery cloth grinding heads, etc. . [0003] Wherein for the processing grinding and polishing of stone, the commonly used grinding heads in the prior art are prone to scratches in the process of processing stone, and the polishing effect is relatively poor and the grindi...
