Embodiment 1
[0018] Taking 100g of deionized water used to prepare general-purpose pitch-based carbon fiber spinning oil as an example, other raw materials and their mass ratios are as follows:
[0019]
[0020] The preparation method is as follows: 100g deionized water, 2g methyl phenyl silicone oil, 5g polypropylene glycol with an average molecular weight of 200, 6g sorbitan fatty acid ester S-20 and 20g acetone are added to the beaker in turn under stirring , heated up to 50°C, stirred at constant temperature for 30 minutes, and then ultrasonicated for 15 minutes with an ultrasonic cleaner to obtain a general-grade pitch-based carbon fiber spinning oil, which has no delamination phenomenon after being placed for 3 months, and its viscosity is 8mPa.s after testing , the light transmittance is 90%, which is basically the same as the appearance, viscosity and light transmittance of the newly prepared oil agent, indicating that its stability is better.
Embodiment 2
[0022] Taking 100g of deionized water used to prepare general-purpose pitch-based carbon fiber spinning oil as an example, other raw materials and their mass ratios are as follows:
[0023]
[0024] Its preparation method is the same as that of Example 1, and the obtained oil agent has no delamination phenomenon after being placed for 3 months, its viscosity is 2 mPa.s after testing, and its light transmittance is 85%.
Embodiment 3
[0026] Taking 100g of deionized water used to prepare general-purpose pitch-based carbon fiber spinning oil as an example, other raw materials and their mass ratios are as follows:
[0027]
[0028] Its preparation method is the same as that of Example 1, and the obtained oil agent has no delamination phenomenon after being placed for 3 months, its viscosity is 10 mPa.s after testing, and its light transmittance is 98%.
