Description

Renewable super-hydrophobic interface material preparation device

Technical Field

The invention belongs to the technical field of new materials, and particularly relates to a preparation device for a renewable super-hydrophobic interface material.

Background

The super-hydrophobic interface (finger contact angle is more than 150 degrees and rolling angle is less than 10 degrees) has unique performance and has extremely important application value in the fields of self-cleaning, waterproof textiles, ice coating prevention, corrosion prevention, drag reduction and the like. In the prior art, a super-hydrophobic interface is prepared, and a lotus leaf-like micron-nanometer complex structure is often constructed, for example, the surface accumulation of nanoparticles is controlled, and fibers formed by electrostatic spinning are controlled to form a rough interface so as to regulate the hydrophobic property of the interface.

In the prior art, eiji Hosono et al ("Superhydrophobic Perpendicular Nanopin Film by the Bottom-Up Process",J.Am.Chem.Soc.,2005,127,13458) control crystal growth on glass substrates by chemical deposition methods, resulting in a complex cobalt compound. These cobalt compounds form a pinpoint micro-nano forest, the diameter of a single pinpoint is about 6.5nm, and the array is several micrometers wide and long. The contact angle of the interface material reaches 178 degrees, but the method has strict conditions, and the material source is strictly limited, so that the interface material is not suitable for mass preparation.

In the prior art, low surface energy compounds such as organic silicon, organic fluorine and the like are introduced to the surface, so that excellent superhydrophobic performance is provided for the surface. However, the first method is complex in operation and high in cost; secondly, the combination degree of the low surface energy compound is poor, and the hydrophobic property is greatly reduced under the influence of environment, such as sun aging and repeated washing or soaping.

The prior art CN201210323328.8 proposes a super-hydrophobic phase-change coating with a micro-nano secondary structure constructed by compounding aqueous fluorosilicone acrylic emulsion, organic phase-change microcapsules and nano particles. The introduced aqueous fluorosilicone acrylic emulsion can reduce interface energy and provide super-hydrophobic performance. And then spraying and the like to obtain the coating with hydrophobic property.

The prior art CN202111088266.2 provides an all-water-based super-hydrophobic coating which uses a fluorine-containing surfactant, a fluorine-containing silane coupling agent, nano titanium dioxide and cellulose and has special chemical composition and reversible wettability. The coating can be irradiated by UV with a certain wavelength for 90min, and the coating with super-hydrophobic/super-hydrophilic reversible conversion can be obtained. The method uses expensive fluorine-containing chemicals, and the preparation method has low preparation efficiency due to higher requirements, so that the prepared coating loses once the superhydrophobic performance of the coating is damaged.

In the prior art, CN201811008002.X, after a polydimethylsiloxane layer and large-particle-diameter silicon dioxide nano particles uniformly distributed on the layer are solidified, a composite super-hydrophobic coating is formed through burning. If the super-hydrophobic coating is damaged, the coating can be burnt by a high-temperature burning such as a propane flame generator, so that the silica nano particles in the coating can be exposed again, and a new super-hydrophobic coating is obtained. The method obtains the super-hydrophobic coating with the renewable capability, but has larger limitation on the selection of raw materials, and more severe regeneration conditions, thus limiting further application.

The prior art CN201210178561.1 obtains a polymer composite membrane by mixing a polymer aggregate with PTFE powder. Superhydrophobicity can be obtained when the surface is polished with a certain pressure. The surface adopts PTFE to obtain low surface energy, and a super-hydrophobic micro-nano structure is produced by a special polishing method. After polishing again, the superhydrophobicity of the material can be regenerated. But this method is also more material-limiting and limits further applications.

In summary, the superhydrophobic interface in the prior art is often disposable and non-renewable, so that the superhydrophobic interface material with wide application range is renewable, which is lack of the prior art and is needed in practical application, and meanwhile, how to rapidly prepare the superhydrophobic interface material by using the preparation device is needed in practical application.

Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Specific implementations of the invention are described in detail below in connection with specific embodiments.

Example 1

Referring to fig. 7 to 13, in one embodiment of the present invention, a renewable super-hydrophobic interface material includes a bilayer structure, one layer is a microcapsule layer, and one layer is an adhesive layer, and is prepared by the following steps:

s1: melting paraffin wax, and mixing the melted paraffin wax with water in which an emulsifier is dissolved in advance to form an O/W emulsion;

S2: a step of adding a wall prepolymer to the emulsion;

s3: maintaining the system for a period of time to obtain paraffin microcapsule suspension;

s4: a step of forming an adhesive layer on a substrate from a mixed solution of an epoxy resin and a curing agent;

s5: adding the controlled release emulsifier into the paraffin microcapsule suspension, uniformly mixing, dispersing on the film in the step 4 to form a microcapsule layer, and slowly solidifying at a temperature slightly higher than the melting point of paraffin to form the renewable super-hydrophobic interface material.

Preferably, the paraffin is selected from n-alkanes with 6-50 carbon atoms and alcohols, esters, carboxylic acids and halogenated derivatives thereof, and the phase change material is selected from n-alkanes with 10-24 carbon atoms and alcohols, esters, carboxylic acids and halogenated derivatives thereof. The paraffin molecular structure is provided with a long alkyl carbon chain and has hydrophobic property, the paraffin material is a hydrophobic material which is cheap and easy to obtain, and has solid-liquid phase transformation characteristic, the paraffin is used as a core material by designing a microcapsule structure, then the paraffin is released under specific conditions, and the hydrophobic property can be improved by utilizing the solid-liquid phase transformation process of the paraffin, so that the super-hydrophobic micro-nano composite structure is formed.

Preferably, the emulsifier comprises at least one of a hydrolysate of a vinyl methyl ether-maleic anhydride copolymer, a hydrolysate of an isobutylene-maleic anhydride copolymer, a hydrolysate of a styrene-maleic anhydride copolymer, a hydrolysate of an ethylene-maleic anhydride copolymer, acacia, gelatin, polyvinyl alcohol, an emulsifier OP, an emulsifier Span, and an emulsifier Tween.

Preferably, the preparation method of the wall material prepolymer comprises the following steps:

S1: adding the silicon precursor into ethanol/water (volume ratio is 1:1) for mixing, and adjusting the pH value of the system to 2 to 3 until uniform sol is obtained;

s2: dissolving diisocyanate and polyethylene glycol in a metering ratio in ethyl acetate, and preserving heat at 50 ℃ for 1 hour in a nitrogen atmosphere to obtain a prepolymer;

s3: urea and 37% formaldehyde solution were mixed in a molar ratio of 1:1.1 to 1:1.5, regulating the pH value to 8.0-9.0, and preserving the temperature at 55-75 ℃ for 30-60 min to obtain a urea-formaldehyde resin prepolymer, wherein melamine and 37% formaldehyde solution are mixed according to the mole ratio of 1: 2-1: 5, after uniformly mixing, regulating the pH value to 8.0-9.0, preserving the temperature at 55-75 ℃ for 30-60 min to obtain melamine resin prepolymer, and mixing 2 prepolymers in proportion to obtain urea formaldehyde-melamine resin prepolymer;

Among them, the mixing mass ratio of 2 resins is preferably 1: 10-10: the mixing mass ratio of 1, preferably 2 resins is 1:3 to 5:1, further, it is preferable that the mixing mass ratio of 2 resins is 1: 2-2: 1.

The microcapsule is a micron-scale core-shell structure formed by taking the paraffin as a core material and taking the precursor as a wall material monomer. In the microcapsule, the mass ratio of paraffin is 45% -90% of the mass of the microcapsule.

Preferably, the emulsifier for controlled release comprises at least one of dodecyl polyethoxy ether, a polymer of propylene oxide and ethylene oxide and alkyl trimethyl ammonium halide with 10-16 carbon atoms, preferably at least one of Brij35, brij56, pluronic F127 and cetyl trimethyl ammonium bromide. The use of the controlled release emulsifier in the interface formation is favorable for forming interface materials with larger contact angles, and in the selection sequence of the controlled release emulsifier, the cationic type is better than the nonionic type, but the anionic type is not preferred, the anionic type is easier to cause explosive release, the structure of paraffin 'growth' is uncontrollable, and the dosage of the controlled release emulsifier is preferably 50-80 times CMC. The Critical Micelle Concentration (CMC) is an important criterion for measuring the micelle forming capacity of a surfactant, and can reflect the surface tension regulating capacity of the surfactant, and the surface tension has a critical meaning in the form of particle size formed when paraffin (oil phase) grows and diffuses outwards.

The slow solidification includes a slow rate of temperature rise that melts the paraffin core.

Preferably, the heating rate is not higher than 10 ℃/min, more preferably, the heating rate is not higher than 5 ℃/min, and the heating end point is preferably 10-20 ℃ higher than the melting point of paraffin.

The renewable, preferred renewable method includes heat treating the interface material with a slow rate of temperature rise that melts the paraffin core.

Preferably, the temperature rising speed is not higher than 10 ℃/min; more preferably, the rate of temperature rise is no higher than 5 ℃/min. The invention obtains the wall material with quasi-linearity and low crosslinking degree through the prepolymer design of the microcapsule wall material. When heated, the paraffin wax in the core material melts and expands in volume, so that the microcapsule wall material is slightly broken, and the paraffin wax grows outwards from the crack. Thus, the microcapsule and the paraffin wax which grows out form a complex micro-nano structure and show superhydrophobic performance.

By controlling the interface formation condition (first interface formation) or regeneration condition, the degree of the outward growth of paraffin can be controlled, and the slow temperature rising speed is beneficial to the formation of complex paraffin-microcapsule microcapsules. If the temperature rise rate is too high, the microcapsules are rapidly broken, and paraffin burst is caused. This is clearly detrimental to the control of the hydrophobic properties of the interface.

Meanwhile, the heating speed is controlled slowly, so that the retention and quantity of paraffin can be regulated and controlled. When the simulation is affected by the external environment, sanding the interface will decrease the superhydrophobicity of the interface or even become hydrophilic. At this time, the temperature is slowly raised again, the paraffin remained in the microcapsule grows outwards again, and the super-hydrophobic interface is regenerated.

The super-hydrophobic interface can realize at least 4-5 times of regeneration and even can reach 10 times of regeneration by adjusting the dosage of the microcapsule, controlling the thickness of the interface and controlling the regeneration condition.

It should be noted that controlling the slow temperature rise is the preferred, but not the only, solution of the present invention. Under other working environments, such as using an organic solvent, regeneration of the superhydrophobic interface can also be realized by utilizing the change of osmotic pressure to replace the temperature change. However, this process is limited by the use of solvents.

The renewable super-hydrophobic interface material can be used for at least one of post-finishing, coating, padding and printing in textile processing technology to obtain the fabric with water-repellent function, and the hydrophobic property of the fabric can be regenerated through a slow heating process.

Besides the textile field, the renewable super-hydrophobic interface material can be also used in the fields of metal anti-corrosion coating, self-cleaning coating, anti-icing interface, thermal protection, thermal interface material, storage and transportation, container and package, building material and the like. After this simple treatment by slow heating, reproducible superhydrophobic properties can be obtained.

The parts in the technical scheme and the embodiment of the invention are mass parts, and the percentages are mass percentages unless otherwise specified.
