Embodiment 1
[0013] The invention is an environment-friendly high water-based cutting fluid for metal processing, which is composed of the following raw materials in parts by weight: 8 parts of refined bio-oil, 1000 parts of deionized water, 0.2 parts of colloidal graphite powder, 0.5 parts of nano-titanium dioxide, 22 parts of sodium sulfite, 16 parts of sodium dioctylsuccinate sulfonate, 5.3 parts of n-undecyl alcohol. The refined bio-oil described herein is the fraction of 60-62°C collected by the bio-oil obtained from the rapid pyrolysis and liquefaction of corn stalks under reduced pressure at 1.3-1.5kPa; the particle size of colloidal graphite powder is 30-40nm; the particle size of nano-titanium dioxide is 90~100nm.
Embodiment 2
[0015] The invention is an environment-friendly high water-based cutting fluid for metal processing, which is composed of the following raw materials in parts by weight: 6 parts of refined bio-oil, 1000 parts of deionized water, 0.1 part of colloidal graphite powder, 1.2 parts of nano-titanium dioxide, 33 parts of sodium sulfite, 6 parts of sodium dioctylsuccinate sulfonate, 0.8 parts of n-undecyl alcohol. Wherein said refined bio-oil is the fraction of 54-56 ℃ that the bio-oil obtained from rapid pyrolysis liquefaction of rice husk is collected under reduced pressure at 1.2-1.3kPa; the colloidal graphite powder particle diameter is 20-40nm; 80~100nm.
Embodiment 3
[0017] The invention is an environment-friendly high water-based cutting fluid for metal processing, which is composed of the following raw materials in parts by weight: 20 parts of refined bio-oil, 1000 parts of deionized water, 2 parts of colloidal graphite powder, 0.2 parts of nano-titanium dioxide, 10 parts of sodium sulfite, 12 parts of sodium dioctylsuccinate sulfonate, 6.8 parts of n-undecyl alcohol. The refined bio-oil described herein is the 60-62°C fraction of the bio-oil obtained from the rapid pyrolysis and liquefaction of corn stalks under vacuum distillation at 1.3-1.5kPa; the particle size of colloidal graphite powder is 30-40nm; the particle size of nano-titanium dioxide is 90~100nm.
