Problems solved by technology

With the continuous development of various modern fields, the demand for abrasive paste is also increasing. The abrasive paste has the economic effect of wear resistance and durability, but the current grinding effect has not yet developed to the ideal state, the surface roughness does not meet the technical requirements, and the polishing speed Slow, low yield
The existing grinding paste powder has poor dispersion characteristics, the microscopic geometry of the main grinding materials is not ideal, the particle size range of the grinding material particles is too wide, and the component lubrication properties are not good, which makes the surface quality of the material after grinding and polishing unsatisfactory, and it is difficult to achieve Quality requirements, the qualified rate of ground products is low
Although most abrasive pastes and liquids can enhance the grinding effect, they are easy to damage the tool when used
In addition, because the abrasive liquid is in liquid form, it is easy to cause waste in use, thereby increasing production costs; and the existing abrasive pastes cannot be well bonded to the substrate, causing the abrasive paste to fall off during the grinding and polishing process, reducing the utilization of the abrasive paste Rate

Abstract

The invention discloses a carbide-base ceramic abrasive paste as well as a preparation method, belongs to the field of cutter polishing and aims to provide a cutter abrasive paste which is rapid in polishing speed, smooth in polishing surface, good in dispersibility and easy to clean. According to the technical scheme, the abrasive paste comprises the following components in parts by mass: 60-70 parts of carbide-base ceramic powder, 10-15 parts of a dispersant, 5-10 parts of a filler, 20-30 parts of a nonionic surfactant, 10-20 parts of a lubricant and 1-5 parts of oxidized polyethylene wax micro powder, wherein the filler is one of vanadium titano-magnetite powder, vanadium titano-magnetite powder or vermiculite powder. When being used in a polishing process for cutter processing, the abrasive paste is capable of effectively improving polishing efficiency, and a cutter surface can be smooth.

Description

technical field [0001] The invention relates to the field of tool polishing, in particular to a carbide-based cermet grinding paste and a preparation method thereof. Background technique [0002] Tool grinding pastes in the prior art are divided into two categories: oil-soluble grinding pastes and water-soluble grinding pastes. Among them, the oil-soluble abrasive paste has the advantages of good wettability, small polishing force, and low polishing heat. It is mainly used for processing parts of high-hard alloy materials such as hard alloy with high finish, instruments, meters, measuring tools, cutting tools, and abrasive tools. etc., but the polishing speed of this type of abrasive paste is slow, and it is not easy to clean; the water-soluble abrasive paste has low viscosity, easy removal and high processing efficiency, and is mainly used for processing slightly corroded metals, circuit boards, glass, ceramics, gemstones, agate, etc. Although metal hard and brittle materi...
