Embodiment Construction

[0013] A No. 4 spindle oil, the raw materials and weight percentages used are as follows:

[0014] 25# transformer oil 35-50%

[0015] Defatted paraffin oil 15 to 40%

[0016] Antioxidant 7-15%

[0017] Dodecenylsuccinic acid 4-14%

[0018] Zinc Phosphate 10 to 25%

[0019] Polyisobutylene 3 to 12%.

[0020] The production method of the No. 4 spindle oil is carried out according to the following steps: at normal temperature and pressure, add 25# transformer oil and degreased paraffin oil into the container, heat it to 80-90 ℃, stir to dissolve all of them, then add antioxidants, ten After the dienylsuccinic acid, polyisobutylene and zinc phosphate are all dissolved in each other after stirring, stop the stirring, lower the temperature below 40°C, sample and test, and enter the packaging process.

[0021] The indicators of the test items are as follows:

Abstract

The invention discloses a No.4 main shaft oil. The No.4 main shaft oil comprises 35-50wt% of 25# transformer oil, 15-40wt% of degreased paraffin oil, 7-15wt% of an antioxidant, 4-14wt% of dodecencylsuccinic acid, 10-25wt% of zinc phosphate and 3-12wt% of polyisobutylene. A production method of the No.4 main shaft oil comprises the following steps: adding 25# transformer oil and degreased paraffin oil to a container at normal temperature under normal pressure, heating to 80-90DEG C, stirring until complete mutual dissolution, sequentially adding the antioxidant, dodecencylsuccinic acid, polyisobutylene and zinc phosphate, stirring, stopping stirring after complete mutual dissolution, cooling to below 40DEG C, sampling, detecting, and packaging.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a No. 4 spindle oil with low cost, thin oil film and integrating functions of lubrication, rust prevention and heat dissipation, and a production method. Background technique [0002] In the manufacturing equipment industry, the rotation accuracy of the spindle of the precision machine tool is very high. However, due to the eccentricity of the bearing and its corresponding bearing clearance between 2 and 20 μm. Therefore, extremely high requirements are placed on the oil film thickness and viscosity of the spindle oil. At present, the oil film thickness, viscosity and rust resistance of the spindle oil used are not ideal, which cannot meet the technological requirements and affect the accuracy of the machine tool spindle. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a ...
