The invention relates to a water-based
cutting fluid for
diamond wire cutting and a preparation method and a use method thereof. The
cutting fluid is mainly prepared from the following components in parts by weight: 8-33 parts by weight of
silicone modified polyether; 3-7 parts by weight of a
silane hydrolysis inhibiting stabilizer; and the balance of water, wherein the total weight part is 100. By implementing the embodiment of the invention, the
cutting fluid has the following beneficial effects that the
cutting fluid has a low-foam self-defoaming function, and a defoaming agent component does not need to be additionally added; the
silicon modified polyether can be subjected to
hydrolysis endothermic reaction on a cutting contact interface, and heat which cannot be taken away in time in the cutting process is balanced; meanwhile, the hydrolyzed
silicon hydroxyl has a strong
adsorption effect and can play roles in protecting the
diamond wire, enhancing the lubricating property, reducing the cutting resistance and reducing the
wire breakage probability; the dispersion of
silicon powder is enhanced and the silicon
powder is enabled not to be agglomerateand, active sites on the surface of the silicon
powder are adsorbed and combined in time so that the problem of
spontaneous combustion caused by high reaction activity of the filter-pressing silicon powder is avoided.
