Description

Technical Field

[0001] The invention belongs to the technical field of marine cable preparation, and in particular relates to a marine cable oil agent and a preparation method thereof. Background Art

[0002] With the rapid development of the marine economy, the market demand for marine textiles, especially for offshore drilling cables, marine ranches, offshore wind power and offshore photovoltaic applications, has increased rapidly, making the market application prospects of high-strength polyester industrial yarns for marine cables increasingly broad. Ordinary high-strength polyester industrial yarns are easily aged and have a short service life in seawater environments due to the influence of factors such as light, salinity and bacteria. It has become a major urgent task for spinning companies to develop high-strength polyester industrial yarns for marine cables that have the high strength, low stretch, high wear resistance and high stability unique to polyester industrial yarns, as well as low water absorption, light resistance, seawater resistance and excellent antibacterial properties.

[0003] The high-strength polyester industrial yarn used for marine cables is made of PET chips, which are melt-spun, stretched and wound by adding an appropriate amount of spinning oil. Among them, the marine cable oil is a functional oil, which is used to evenly coat a layer of marine oil on the surface of the tow after the stretching and shaping process, so that the oiled tow has excellent seawater corrosion resistance and light resistance.

[0004] CN102465447A discloses a polyester fiber surface coating material for marine cables and a production process. The coating material for marine cables can give polyester fibers excellent water resistance and wear resistance, but it is in a silicone wax emulsion state, which will precipitate when left at low temperatures, easily clogging oil pipes and affecting the uniformity of oiling.

[0005] Therefore, it is of great significance to develop a new type of marine cable oil. Summary of the invention

[0006] Purpose of the invention: The purpose of the present invention is to provide a marine cable oil and a preparation method thereof. The marine cable oil of the present invention not only ensures excellent wear resistance, but also solves the problems of insufficient stability and poor oiling uniformity commonly found in existing marine cable oils.

[0007] Technical solution: The purpose of the present invention is achieved through the following technical solution:

[0008] The invention provides a marine cable oil, which consists of polysiloxane, a lubricant, an antiseptic and a wear-resistant agent, wherein the polysiloxane accounts for 50-80% of the total mass of the oil, the lubricant accounts for 5-30% of the total mass of the oil, the antiseptic and a wear-resistant agent accounts for 1-15% of the total mass of the oil, and the wear-resistant agent accounts for 2-10% of the total mass of the oil; the total mass of the polysiloxane, the lubricant, the antiseptic and a wear-resistant agent is 100%.

[0009] The marine cable oil of the present invention is composed of polysiloxane, a smoothing agent, a bactericidal preservative and an anti-wear agent. Among them, polysiloxane can interact with polyester fiber filaments, play a certain isolation role, and improve water resistance and lubricity; the smoothing agent can further improve lubricity; the antiseptic bactericidal agent can inhibit various bacteria in seawater; and the anti-wear agent can improve the wear resistance of industrial yarn. Polysiloxane, smoothing agent, bactericidal preservative and anti-wear agent form a mutually soluble system, and each component works synergistically to improve the water resistance and wear resistance of the fiber filament; the marine cable oil product is a homogeneous solution, which is convenient for oiling.

[0010] A preferred embodiment of the present invention is that the polysiloxane accounts for 50-80wt% of the total mass of the oil, the lubricant accounts for 15-30wt% of the total mass of the oil, the preservative and bactericidal agent accounts for 3-10wt% of the total mass of the oil, and the anti-wear agent accounts for 5-10wt% of the total mass of the oil; the mass of the polysiloxane, the lubricant, the preservative and bactericidal agent and the anti-wear agent sum to 100%.

[0011] Preferably, the polysiloxane is one or more of polymethylphenylsiloxane, polydimethylsiloxane, polymethylhydrogensiloxane, aminopropyl-terminated polydimethylsiloxane, polymethylethoxysiloxane, hydroxy-terminated polydimethylsiloxane, polymethylvinylsiloxane or polyether-modified trisiloxane.

[0012] Polysiloxane has excellent waterproof properties, especially modified polysiloxane, which can undergo certain physical and chemical reactions with polyester fibers under use conditions and is an indispensable component with excellent waterproof properties.

[0013] Further preferably, the polysiloxane is one or more of polymethylphenylsiloxane, polydimethylsiloxane, polymethylhydrogensiloxane or hydroxyl-terminated polydimethylsiloxane.

[0014] Preferably, the viscosity of the polysiloxane at 25° C. is 5-500 cst. The appropriate viscosity range facilitates oiling of polyester fibers and ensures an appropriate oil content of the fibers.

[0015] More preferably, the viscosity of the polysiloxane at 25° C. is 50-350 cst.

[0016] Preferably, the smoothing agent is selected from one or more of fatty acid esters, fatty acid polyoxyethylene ethers, base oils or vegetable oils.

[0017] Further preferably, the base oil is white oil, 60N~250N base oil; the vegetable oil is one or more of hydrogenated castor oil, palm oil or soybean oil; the fatty acid ester is C10~C18 fatty acid ester; the fatty acid polyoxyethylene ether is C8~C16 fatty acid polyoxyethylene ether.

[0018] Furthermore, the smoothing agent is selected from one or more of methyl laurate, methyl myristate, methyl hexadecanoate, methyl oleate, C8-C16 fatty acid polyoxyethylene ether, white oil, 60N-250N base oil, hydrogenated castor oil or palm oil.

[0019] Furthermore, the lubricant is selected from at least one of methyl laurate, methyl hexadecanoate, polyoxyethylene lauryl fatty alcohol ether, white oil or 60N~250N base oil.

[0020] The smoothing agent selected by the present invention has good anti-oxidation and anti-coking properties.

[0021] Preferably, the preservative and fungicide is selected from one or more of N-octylisothiazolinone, benzisothiazolinone, 2-butyl-1,2-benzisothiazolin-3-one, methylisothiazolinone, dodecyldimethylbenzyl ammonium chloride or benzalkonium chloride.

[0022] Since most bacteria in seawater are Gram-negative rods, the antiseptic and bactericidal agent selected in the present invention has a good inhibitory effect on such bacteria and has good compatibility with other components.

[0023] Preferably, the anti-wear agent is selected from one or more of bisphenol A epoxy acrylate, epoxy acrylate or aliphatic polyurethane acrylate. The effective functional groups in the anti-wear agent can react with polyester fibers to form a film on the fiber surface to improve adhesion.

[0024] The present invention also provides a method for preparing the above-mentioned marine cable oil, comprising the following steps:

[0025] Firstly, polysiloxane and anti-wear agent are dissolved and fully mixed at 40-60° C., and then a lubricant and an antiseptic and bactericidal agent are added in sequence and fully mixed at room temperature to obtain the marine cable oil.

[0026] The marine cable oil agent of the present invention is a functional oil agent, which is used for the qualitative drawing of industrial yarns. When the addition amount is 1-2wt%, the wet wear resistance reaches more than 10,000 times. Beneficial Effects

[0027] The polysiloxane, lubricant, bactericidal preservative and anti-wear agent in the marine cable oil of the present invention form a mutually soluble system, and the components work synergistically to improve the water resistance and wear resistance of the fiber; the marine cable oil product is a homogeneous solution, which is convenient for oiling. Therefore, the marine cable oil product of the present invention has the advantages of excellent wear resistance, good stability, convenient oiling, simple preparation method and green environmental protection.
