Embodiment 1

[0029] According to the parts by weight, weigh 19 grams of S-85, 11 grams of T-85, 2 grams of OP-4, 2 grams of n-propanol, 8 grams of n-octanol, 8 grams of PB2400, 2 grams of PEG200, at room temperature 20 ℃ Next, stir for 25 minutes until completely uniform.

[0030] Weighing 2.5% by weight of the bunker oil emulsifier composition and adding it to the bunker oil product, stirring evenly to prepare the oil for experiment, which is set aside. Add 10% by weight of water to the prepared experimental oil, stir for 25min, adopt the standing method to investigate the stability of the emulsion, leave the prepared emulsion at room temperature, record the change over time, the amount of precipitation of water, the same The less water precipitated in the emulsion during the time, the more stable the emulsion.

[0031] The particle size of dispersed phase in emulsifiable concentrate was determined by dynamic light scattering instrument NanoZS. For the emulsion, the smaller the particle...

Embodiment 2～5

[0035] Prepare bunker oil emulsifier composition and experimental oil by each step of [Example 1], just change the consumption and composition of each component, its bunker oil emulsifier composition composition is shown in Table 1.

[0036] Test the wear scar diameter, liquid phase corrosion and copper sheet corrosion of each experimental oil. The experimental results are shown in Table 2. The experimental oil particle size and static stability test results are shown in Table 3.

Abstract

The invention relates to a marine oil emulsifier composition and application thereof which mainly solve the problem that in the prior art, system oil for a screw shaft cannot form stable emulsifying oil when the system oil encounters water. The marine oil emulsifier composition is prepared from, by weight, 0.1-80 parts of ester compounds, 0.1-50 parts of phenolic ether compounds, 0.1-50 parts of fatty alcohol and 0.1-50 parts of polymers; at least one of sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester and polyethylene glycol fatty acid ester is selected as the ester compounds, at least one of a TX series and an OP series is selected as the phenolic ether compounds, at least one of methyl alcohol, ethyl alcohol, n-propyl alcohol, n-butyl alcohol, n-amyl alcohol, n-hexyl alcohol, n-heptanol, n-caprylic alcohol and isooctyl alcohol is selected as the fatty alcohol, and at least one of polyethylene glycol, polyisobutene and ethylene-propylene copolymers is selected as the polymers. According to the marine oil emulsifier composition and the application thereof, the problem is better solved, and the marine oil emulsifier composition can be applied to industrial production.

Description

technical field [0001] The invention relates to a bunker oil emulsifier composition and its application. Background technique [0002] The seal design of the ship stern shaft has always been a challenging subject, and the oil leakage or water ingress of the stern shaft caused by the flaws in the seal design of the stern shaft is even more difficult. In the actual operation of the ship, due to the complex environmental factors, especially in severe weather conditions, when the propeller is running, it is inevitable that there will be large vibration or sea damage, which will lead to the failure of the stern sealing device, resulting in oil leakage or water entry. Water ingress to the stern shaft occurs frequently, which is a common failure. If the oil contains too much water, it will reduce or even lose its lubricating performance, which will lead to the wear of the parts and the corrosion of the equipment. Moisture and metal particles produced by wear and tear accelerate th...
