Embodiment 1
[0047] The production of embodiment 1 lubricating oil viscosity index improver
[0048] (1) Pump part of the base oil into the reaction kettle, heat up while stirring, when the temperature reaches 80°C-100°C, open the glue inlet, and add an appropriate size of ethylene-propylene copolymer dry glue that has been cut into blocks , heat up at a rate of about 10°C / hour, sol, the temperature rises to 140°C, conduct a central control test, and the sol ends after passing the test.
[0049] (2) Continue to heat up to 270°C, and start to introduce air or oxygen, add the controllable degradation catalyst into the reactor, stir at 270°C for 1 hour, after the central control test passes, stop the air supply and heating, and turn on the cooling, make up The rest of the base oil was cooled to 120°C.
[0050] (3) Sampling at the filling port, measure product quality according to Q / SYRH4001-2002 or SH / T0622-2007 standards, and fill after passing the test.

Embodiment 2
[0052] The production of embodiment 2 lubricating oil viscosity index improver
[0053] (1) Pump part of the base oil into the reaction kettle and heat up while stirring. When the temperature reaches 80°C, open the glue inlet and add an appropriate size of ethylene-propylene copolymer dry glue that has been cut into blocks to the kettle. Heat up at a rate of about 10°C / hour, sol, the temperature rises to 135°C, conduct a central control test, and the sol ends after passing the test.
[0054] (2) Continue to raise the temperature to 230°C, and start to introduce air or oxygen, add a controllable degradation catalyst, and degrade for 2 hours. After passing the central control test, stop the air supply and heating and turn on the cooling to make up the remaining base oil.
[0055] (3) Sampling at the filling port, measure product quality according to Q / SYRH4001-2002 or SH / T0622-2007 standards, and fill after passing the test.

Embodiment 3
[0057] The production of embodiment 3 lubricating oil viscosity index improver
[0058] (1) Pump part of the base oil into the reaction kettle, and heat up while stirring. When the temperature reaches 80°C, open the glue inlet, and add an appropriate size of ethylene-propylene copolymer dry glue that has been cut into blocks, and use 10 ℃ / hour rate of temperature rise, sol, the temperature rises to 135 ℃, the central control test is carried out, and the sol ends after passing the test.
[0059] (2) Continue to raise the temperature to 190°C, and start to introduce air or oxygen, add a controllable degradation catalyst, and degrade for 4 hours. After passing the central control test, stop the air supply and heating and turn on the cooling to make up the remaining base oil.
[0060] (3) Sampling at the filling port, measure product quality according to Q / SYRH4001-2002 or SH / T0622-2007 standards, and fill after passing the test.
