| titleOfInvention | Special grinding fluid for ductile regime lapping of optical glass and preparation method of special grinding fluid |
| abstract | The invention discloses a preparation method of a special grinding fluid for ductile regime lapping of optical glass. The preparation method comprises the steps of: at room temperature, adding sodium carbonate in water, stirring; heating, sequentially adding potassium tetraborate, benzotriazole, hexamethylenetetramine and sodium molybdate under the condition of continuously stirring; heating, sequentially adding triethanolamine and polyethylene glycol; and cooling the liquid to room temperature under the condition of stirring, and continuously stirring for 5-30min to obtain the special grinding fluid for ductile regime lapping of optical glass. The grinding fluid prepared by adopting the preparation method has better functions of cooling, lubricating, rust preventing and cleaning, the surface of the optical glass is chemically modified through the components in the grinding fluid, a microcosmic network structure of the optical glass is broken, the physical form of the material surface is changed, the bond energy of a bond is weakened, the hardness of the surface of the optical glass is reduced, the critical grinding depth value of crispness-ductility transformation of the optical glass is increased, and the difficulty in realizing the ductile regime lapping of the optical glass industrially is lowered. |
