[0045] refer to figure 1 , a preparation method of non-ferrous metal grinding heat conduction blocking lubricant, non-ferrous metal grinding heat conduction blocking lubricant comprises blocking agent, and the preparation method of blocking agent comprises the following steps:
[0046] S110: Prepare raw materials according to the above blocking agent ratio.
[0047] S120: heating paraffin wax, ozokerite, rosin and polyvinyl chloride powder to 540-600° C., stirring well to obtain the first viscous liquid.
[0048] S130: heat the first viscous liquid for 2-4 minutes, add montan wax under stirring, and cool to obtain the blocking agent.
[0049] Heat to 540-600°C to melt paraffin wax, ozokerite, rosin and polyvinyl chloride powder. Since the specific gravity of paraffin is the lightest, it needs to be stirred continuously during the heating process, otherwise the PVC powder is difficult to mix evenly. When viscous liquid is obtained, stop heating after keeping warm to remove hea...
Embodiment 1
[0058] The non-ferrous metal grinding heat conduction blocking lubricant includes a blocking agent, and the blocking agent is composed of 28% ozokerite, 26% paraffin, 31% polymerized rosin, 5% polyvinyl chloride powder and 10% montan wax. Heat paraffin wax, ozokerite, rosin and polyvinyl chloride powder to 600°C, stir continuously to make it homogeneous to obtain the first viscous liquid. After the first viscous liquid was kept warm for 2 minutes, the heating was stopped. When the viscous liquid is cooled to 70°C, add montan wax and cool to obtain blocking agent.
[0059] The non-ferrous metal grinding heat conduction blocking lubricant is applied in the processing technology of parts, and the parts are made of aluminum. Apply non-ferrous metal grinding heat conduction blocking lubricant on the white corundum grinding wheel, the precision of the processed parts is high, and the roughness of the processed surface of the parts is 0.7.
Embodiment 2
[0061] The non-ferrous metal grinding heat conduction blocking lubricant includes a blocking agent, and the blocking agent is composed of 36% ozokerite, 29% paraffin, 24% polymerized rosin, 3% polyvinyl chloride powder and 8% montan wax. Heat paraffin wax, ozokerite, rosin and polyvinyl chloride powder to 540°C, and keep stirring to make it homogeneous to obtain the first viscous liquid. The first viscous liquid was kept warm for 4 minutes and then the heating was stopped. When the viscous liquid is cooled to 90°C, add montan wax and cool to obtain blocking agent.
[0062] The non-ferrous metal grinding thermal conduction blocking lubricant is applied to the processing technology of a certain part, and the part is made of magnesium alloy. Apply non-ferrous metal grinding heat conduction blocking lubricant on the white corundum grinding wheel, the precision of the processed parts is high, and the roughness of the processed surface of the parts is Ra0.4.
