Problems solved by technology

However, the existing diamond polishing fluid is usually high-viscosity, which needs to be diluted before use, and the high viscosity of the diamond polishing fluid will cause poor heat dissipation, and the low viscosity will cause poor suspension stability.
Dilution before use increases operating steps, which affects work efficiency; and the concentration of dilution is not easy to control, resulting in inconsistent quality of polished products

Abstract

The invention discloses a diamond suspension grinding and polishing solution, which is prepared from the following raw materials in parts by weight: 2 to 8 parts of sodium polyacrylate, 3 to 10 parts of propylene glycol, 1 to 8 parts of NNO dispersing agent, 3 to 8 parts of defoaming agent, 2 to 5 parts of triethanolamine, 8 to 15 parts of cellulose ether, 10 to 30 parts of diamond micro powder and 70 to 95 parts of purified water. The invention further discloses a preparation method of the diamond suspension grinding and polishing solution. The obtained polishing solution can be directly used, so that the step of diluting again is omitted, the machining efficiency is improved, and the stability of the quality of a polished product is improved.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing, in particular to a diamond suspension grinding and polishing liquid and a preparation method thereof. Background technique [0002] In the mechanical polishing technology, the polishing fluid is the key element, which directly affects the surface quality of the product after polishing. Diamond is widely used in polishing fluids due to its ultra-high hardness, strength and willfulness. Diamond polishing fluid can quickly take away the heat and grinding debris generated during the machining process to improve machining accuracy. However, the existing diamond polishing liquid is usually high viscosity, and needs to be diluted before use, and the high viscosity of the diamond polishing liquid will cause poor heat dissipation, and the low viscosity will cause poor suspension stability. Dilution before use increases operating steps, which affects work efficiency; and the concentration ...
