Description
Technical Field
The invention belongs to the technical field of organic gel coatings, and particularly relates to an ultra-lubricating organic gel coating with self-adaptability and abrasion resistance and a preparation method thereof.
Background
Super-lubricating materials (slip surface) imitating nepenthes are a type of solid-liquid composite structure interface materials (Nature, 2011,477,443-447) which have been developed in recent years, and form stable and inert smooth surfaces by pouring water/oil lubricants into rough substrates of nano/micro structures. The surface has the characteristics of good lyophobicity, ice resistance, pressure stability and the like. In the actual use process, the lubricating liquid on the surface gradually runs off when the super-lubricating surface is worn by external machinery, so that the wettability of the super-lubricating surface is reduced, and the service life of the super-lubricating surface is possibly shortened seriously. Therefore, the wear resistance of the material needs to be focused on when preparing the super-lubricating material, but the current lubricating material often does not have the wear resistance, for example, patent CN107761039B, CN113522684A, CN108855832A, CN105670348A respectively utilizes flame spraying, laser etching, hydrolysis method and sol-gel method to prepare a rough substrate, and then obtains the super-lubricating material after being modified by low surface energy substances and covered by lubricating oil. Most of the surfaces of the super-lubricating materials are failed due to friction loss of lubricating oil, so that the application range of the super-lubricating materials is greatly limited. Thus, the preparation of a super-lubricating material with an abrasion-resistant nepenthes-like structure is an urgent problem to be solved at present.

And then modifying hydroxyl-terminated PDMS by using a green aqueous solvent method through a silane coupling agent to enable the hydroxyl-terminated PDMS to be covalently grafted with a photosensitive group (C=C), and carrying out ultraviolet irradiation induced polymerization reaction to obtain a PDMS network structure, and simultaneously, converting high-melting-point lubricating oil from a liquid state to a solid state at a low temperature, so that the loss of the liquid lubricating oil caused by the influence of external environment can be reduced, and the service life of the coating can be prolonged. Meanwhile, in order to reduce the abrasion of the external environment to the solid lubricant and overcome the defect of poor lubricity of the solid lubricant, under the condition of being higher than the melting point of the lubricating oil, the lipid vesicle embedded with the water-based lubricant glycerol is embedded into a PDMS crosslinked network together with the lubricating oil, at the moment, the PDMS network is rapidly swelled, and when the temperature is reduced, on one hand, the swelling rate of the PDMS network is reduced; on the other hand, when the lubricating oil is converted from a liquid phase to a solid phase, the volume expansion is generated, the stress of the elastic organic gel is released, so that the lubricating oil and the lipid vesicles in the reservoir are secreted to the surface, when the surface is impacted or mechanically damaged by the outside, the rupture of the lipid membrane can promote the release of the glycerin of the water-based lubricant embedded in the vesicles, and the glycerin can rapidly fill and cover the defects generated by the abrasion of the solid lubricating oil through diffusion, so that the super-lubricating material with a solid-liquid composite structure is formed, and the liquid lubricating performance is realized. Compared with the existing super-lubricating surface material (slip surface), the method has the advantages that the friction resistance of the lubricating material is greatly enhanced, meanwhile, the interface lubricity is not lost, and the service life of the lubricating coating is effectively prolonged due to the existence of a crosslinked network and embedded vesicles.

Step two, preparation of a methacrylate modified polydimethylsiloxane (MA-PDMS) solution:
taking a 100mL dry and clean single-neck flask, uniformly stirring and mixing PDMS, a silane coupling agent, a catalyst DTBL and deionized water at room temperature according to the molar ratio of 1:40:2:130, and then placing the obtained solution in an oven for decompression and dehydration at 60 ℃. And then placing a photoinitiator 1173 (HMPP) with the mass fraction of 5% into the mixed solution, and uniformly stirring at room temperature to obtain an MA-PDMS solution.
Step three, preparation of a methacrylate modified polydimethylsiloxane (MA-PDMS) film:
taking the MA-PDMS polymer solution prepared in the second step (the concentration is 2mg/mL, and the solvent is water). The MA-PDMS polymer solution prepared as described above was sprayed onto a glass substrate on which a polydopamine coating had been formed, and then subjected to photopolymerization under a UV lamp (365 nm) for 30 seconds to obtain a methacrylate-modified polydimethylsiloxane (MA-PDMS) film.
Step four, preparing lipid vesicles embedded with glycerol:
60mg of POPC was dissolved in 2mL of chloroform, transferred to a round-bottomed flask, and subjected to rotary evaporation under reduced pressure at 37℃for 1 hour to give a uniform lipid film, and 1mL of glycerol was added to the round-bottomed flask and hydrated at 60℃for 60 minutes. Then placing the flask under ice bath, and performing ultrasonic reaction for 5 times (power 50W, work 2s, and pause 2 s) by a probe to obtain the glycerol-embedded lipid vesicle.
Step five, constructing an adaptive super-lubrication gel coating:
under the condition that the temperature is higher than the melting point of palm oil, mixing the palm oil with lipid vesicles embedded with glycerol to obtain coating liquid (the mixing volume ratio is 2:8), immersing the obtained MA-PDMS film in the coating liquid, swelling for 5 hours, taking out the swelled organic silicon gel, and cooling for later use.
The silicone gel prepared in example 2 was tested and the test results are shown in fig. 2 and 3. In fig. 2, A, B is a water contact angle plot and a sliding angle plot, respectively, of a glass non-sand rubbed surface coated with the superlubricated organogel coating of example 2; C. d is the n-hexane contact angle plot and sliding angle plot, respectively, of the glass coated with the superlubricated organogel coating of example 2 after 20 times of sand spin rubbing. FIG. 3 is a physical diagram of glass coated with the super-lubricious organogel coating of example 2, rubbed 20 times in sand. As can be seen from the graph, the super-lubricating organic gel coating has self-adaptability, greatly enhances the friction resistance of the lubricating material, does not lose the interface lubricity, and effectively prolongs the service life of the lubricating coating.
