This paper focuses on the hydrophilic modification of the nano-graphite prescription new water-based cutting fluid, synthesized by free radical emulsion polymerization of nano-graphite / acrylate hybrid emulsion, and the hybrid emulsion as an additive was added to the diluted The commercially available water-based cutting fluid, in order to improve the lubricating properties of water-based cutting fluid. Were characterized by means of UV and visible light spectrophotometer, and scanning electron microscopy (SEM) on the emulsion results show that: the use of methacrylate aggregate coated nano-graphite modified the initial realization of nano-graphite in water-based liquid the stability of the dispersion, and to determine the best polymerization conditions were as follows: 5 h, 70 ° C. The four-ball friction and wear tester, and surface tension meter composite emulsion and composite cutting fluid lubrication performance assessment results showed that: the modified nano-graphite liquid surface tension is reced, increased wettability, while adding the nano-graphite cutting fluid rece the friction coefficient, the smaller the wear scar diameter of PB value increases, the water based cutting fluid lubrication performance improved significantly.

A, nanographite hydrophilic Modification of water is commonly used in the dispersion medium, and give full play to the function of nano-graphite can not be separated from water. Graphite non-polar solid material, natural hydrophobicity. Unremitting exploration around the theme of people. Huijuan such as water, ethanol, and ethanol - aqueous solutions and polar liquids such as the dispersion medium of pH value, the dispersion medium, dispersion properties of dispersant on nano-graphite. The results showed that the pH value of 10 ~ 11:00, the system of Zeta potential maximum, then the system is the most stable.追问敢不敢完整的

一般就是接枝或者功能化,加入亲水基团或者亲水聚合物。
随便google学术一下就有。
