Diamond grinding fluid for stable full-suspension grinding and preparation method of diamond grinding fluid

The invention relates to stable diamond grinding fluid for full-suspension grinding. The stable diamond grinding fluid is prepared from the following raw materials in parts by weight: 0.5-15 parts of diamond micro powder, 1-50 parts of a density regulator, 0.01-10 parts of a suspending agent, 0.1-5 parts of a fluidity regulator, 0.1-5 parts of a viscosity regulator, 1-50 parts of a lubricant, 0.0001-0.5 part of a defoaming agent and 10-90 parts of water. Compared with the existing grinding fluid in a semi-suspension or non-suspension state, the product provided by the invention has better product quality impression; when being applied to grinding machining, the grinding fluid is stable in performance and has better machining efficiency and machining surface quality; and when the device is applied to batch production of the grinding and polishing liquid, the hidden worry of uneven filling caused by sedimentation and aggregation is avoided, and batch stable production can be realized. 本发明涉及一种稳定全悬浮研磨用金刚石研磨液，其由下述
