Embodiment 1
[0015] A method for making a sponge polishing wheel, comprising the steps of:
[0016] (1) Preparation of steel roller core: mix 15% mullite powder, 7% lanolin, 15% synthetic resin, 8% silica sol, and 18% sand and add 23% aluminum oxide powder, 3% zinc oxide, After the 0.1% calcium oxide powder is mixed, it is poured into a roller machine for extrusion molding, and then baked in a low-temperature oven for 4 hours;
[0017] (2) Preparation of steel roller core coating: get 15% of the dispersed alumina solution in the container, then put 6% of Y 2 o 3 powder and 35% ZrO 2 Put the powder into the container and stir for 35 minutes; spray the baked steel roller core clean, put it into the above stirring liquid and immerse in the paint, then take out the steel roller core and dry it at room temperature for 15 hours, then put it in an oven at 500°C for baking Bake for 1 hour;
[0018] (3) Evenly coat the periphery of the steel roller core coated in step (2) with a layer of adhesi...
Embodiment 2
[0021] A method for making a sponge polishing wheel, comprising the steps of:
[0022] (1) Prepare the steel roller core: mix 20% mullite powder, 9% lanolin, 23% synthetic resin, 11% silica sol, and 27% sand, then add 34% aluminum oxide powder, 5% zinc oxide, After 0.3% calcium oxide powder is mixed, it is poured into a roller machine for extrusion molding, and then baked in a low-temperature oven for 5 hours;
[0023] (2) Preparation of steel roller core coating: get 20% of the dispersed alumina solution in the container, then put 8% of Y 2 o 3 powder and 40% ZrO 2 Put the powder into the container and stir for 40 minutes; spray the baked steel roller core clean, enter the above stirring liquid and immerse in the paint, then take out the steel roller core and dry it at room temperature for 18 hours, then put it in an oven at 500°C for baking Bake for 1.5 hours;
[0024] (3) Evenly coat the periphery of the steel roller core coated in step (2) with a layer of adhesive, whi...
Embodiment 3
[0027] A method for making a sponge polishing wheel, comprising the steps of:
[0028] (1) Prepare steel roller core: add 27% aluminum oxide powder, 4% zinc oxide, After the 0.2% calcium oxide powder is mixed, it is poured into a roller machine for extrusion molding, and then baked in a low-temperature oven for 3 hours;
[0029] (2) Preparation of steel roller core coating: get 18% of the dispersed alumina solution and place it in the container, then put 8% of Y 2 o 3 powder and 36% ZrO 2 Put the powder into the container and stir for 37 minutes; spray the baked steel roller core clean, enter the above stirring liquid and immerse in the paint, then take out the steel roller core and dry it at room temperature for 17 hours, then put it in an oven at 500°C for baking Bake for 0.8 hours;
[0030] (3) Evenly coat the periphery of the steel roller core coated in step (2) with a layer of adhesive, which includes epoxy resin, polyamine curing agent and reinforcing filler; wherein...
