Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a UV-cured super-hydrophilic antifogging coating and a preparation method and application thereof.
Background
The transparent material has a light transmittance of 80% or more for visible light having a wavelength of 400 to 800 nm. Glass is the most commonly used inorganic transparent material. In the daily use process, the surface of the glass is easy to be atomized and dewed, thereby influencing the use of the glass. The fogging phenomenon of glass brings a lot of troubles to people and even can cause huge economic loss to people. For example, in cold seasons with low air temperature, the fogging of the glasses and various protective masks affects the sight of people, thereby obstructing people's travel; the fogging of the windshield of the automobile can cause huge potential safety hazards to people during driving; for another example, when the mist droplets are condensed on the lens surface of a precision analysis instrument such as an infrared optical microscope, the accuracy of analysis thereof may be reduced; when the fog drops are condensed on the light-transmitting plate of the solar cell, the solar energy absorption efficiency is reduced, so that the solar cell equipment is not favorable for fully playing the due role. Therefore, it is a very important subject to be studied to prevent fogging and condensation of glass.
The antifogging material is a functional coating for slowing down or preventing the atomization or condensation phenomenon on the surface of the transparent substrate. Generally, antifogging coatings are mainly classified into inorganic-system antifogging coatings, organic-system antifogging coatings, and organic-inorganic hybrid-system antifogging coatings. Surface coating with anti-fogging coatings is a more common method for eliminating fogging: firstly, the hydrophilic polymer coating is used, so that the contact angle (theta) of water on the surface of the material is reduced, the water is spread and thinned, the diffuse reflection is reduced, light rays can well penetrate through the material, but the hydrophilic polymer coating can form hydrogen bonds or stronger polar bonds, the room temperature viscosity is higher, the leveling property is poor, the uniform spreading is not easy, and the corrosion resistance is also poor; secondly, the hydrophobic polymer coating is used to increase the contact angle of water on the surface of the material, and after water drops form water drops, the water drops are difficult to stay on the surface due to the action of gravity, so as to achieve the anti-fog purpose.
CN112680103A discloses an ultrahigh-strength hydrophobic antifogging coating composition and application thereof. The antifogging coating composition is prepared from the following raw materials in parts by weight: 100 parts of resin-based polymerized monomer, 1-3 parts of modified silicon carbide crystal whisker, 1-3 parts of photoinitiator, 0.1-0.3 part of flatting agent and 0.3-0.5 part of defoaming agent; the resin matrix comprises 60-80 parts of silicon acrylate oligomer and 20-40 parts of silicon acrylate monomer. According to the technical scheme, the mixture of the silicon-containing acrylate oligomer and the silicon-containing acrylate monomer is used as a polymerization monomer, the prepared composition has excellent water resistance, light resistance and hydrophobicity, and the modified silicon carbide crystal whisker is added to play an excellent mechanical property enhancing role, so that the cured coating has ultrahigh strength, scratch resistance and hydrophobicity, but the antifogging property is poor, if extremely small water drops in fog are encountered, when the surface acting force between the water drops and the coating is greater than the self gravity, the antifogging effect cannot be achieved.
CN111849333A discloses a SiO2A preparation method of hydrophilic modified UV-cured waterborne polyurethane antifogging coating. The preparation method comprises the following steps: firstly, synthesizing waterborne polyurethane, then preparing nano silica sol by hydrolyzing tetraethoxysilane TEOS, finally introducing the nano silica sol into the waterborne polyurethane to generate a cross-linking structure in situ, and curing to obtain SiO2Hydrophilic modified UV-cured waterborne polyurethane antifogging coating. The SiO prepared by the technical scheme2The hydrophilic modified UV-cured waterborne polyurethane antifogging coating has good hydrophilicity, weather resistance and wear resistance, but has poor water resistance.
CN106752857A discloses a preparation method of a dual-curing acrylate super-hydrophilic antifogging coating. According to the preparation method, acrylate monomers are used as main raw materials, a silane coupling agent, hydroxyethyl acrylate and a sulfonic acrylamide monomer are introduced by adopting free radical polymerization, and double bonds are introduced by adopting half-terminated polyurethane and hydroxyl in a main chain to react. Wherein the sulfonic acid group on the main chain can endow the coating film with good hydrophilicity; the silane coupling agent and the tetraethoxysilane can be hydrolyzed and cured to form a coating, and meanwhile, the non-condensed silicon hydroxyl can further improve the hydrophilicity of the coating and endow the coating with good antifogging performance; the introduction of double bonds enables photocuring of acrylates. The coating prepared by the technical scheme has better hydrophilicity.
In the prior art, the hydrophilic polymer coating may form hydrogen bonds or strong polar bonds, has high room temperature viscosity and poor leveling property, is not easy to uniformly spread, has poor corrosion resistance, and has poor water resistance and short antifogging time. Therefore, how to provide a coating with good hydrophilicity, good water resistance and durable antifogging effect is a technical problem to be solved at present.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a UV-cured super-hydrophilic antifogging coating and a preparation method and application thereof. According to the invention, through the design of raw material components in the UV-cured super-hydrophilic anti-fog coating and the matched use of the surfactant and the modified two-dimensional nano material, the surfactant can be uniformly dispersed in the anti-fog coating, so that the prepared anti-fog coating has good water resistance and long-time anti-fog effect.
In order to achieve the purpose, the invention adopts the following technical scheme:

the modified two-dimensional nano material comprises the following raw materials in parts by weight: 0.5-2 parts of a two-dimensional nano material and 0.5-3 parts of a modifier;
the modifier is selected from an acrylic acid modifier or an acrylate modifier.
In the prior art, the antifogging coating prepared by the hydrophilic antifogging coating has a good antifogging effect because a surfactant in the antifogging coating can move and migrate in the coating and is enriched on the surface of the coating, so that the coating has good hydrophilicity, the contact angle of water on the surface of the coating can be reduced, the water is spread and thinned, and the antifogging effect is achieved. However, when the surfactant is concentrated on the surface of the coating, the surfactant is separated from the coating along with the movement of the water film, so that the coating loses the antifogging effect. Therefore, the hydrophilic antifogging coating has poor water resistance and short antifogging time.
According to the invention, the two-dimensional nanomaterial is modified by the modifier, so that the surface of the two-dimensional nanomaterial contains carbon-carbon double bonds, and the modified two-dimensional nanomaterial can carry out polymerization reaction with UV resin oligomer and acrylic monomer to form an antifogging coating when the antifogging coating is prepared subsequently. Therefore, the modified two-dimensional nano material can be stably and uniformly dispersed in the coating. Meanwhile, the surfactant is matched with the modified two-dimensional nano material for use, and the surfactant is further uniformly dispersed on the surface or in the modified two-dimensional nano material, so that the surfactant is uniformly dispersed in the coating along with the modified two-dimensional nano material, and the coating has better hydrophilicity; on the other hand, the modified two-dimensional nano material can slow down the motion and the migration of the surfactant in the coating, so that the coating has better hydrophilicity, better water resistance and better antifogging durability.
The modified two-dimensional nano material exists as a bridge connecting the surfactant and a coating matrix (namely UV resin oligomer and acrylic monomer), the surfactant can be uniformly dispersed in the coating matrix through the modified two-dimensional nano material, and the motion of the surfactant in a coating can be slowed down by the existence of the modified two-dimensional nano material, so that the UV-cured super-hydrophilic antifogging coating has good hydrophilicity, good water resistance and a long-time antifogging effect.
