Description
Technical Field
The invention belongs to the field of water-based paint, and particularly relates to water-based antifogging paint and a preparation method thereof.
Background
Fog is a common phenomenon in daily life. Because there is a significant temperature difference between two sides of some interface materials, such as glass, plastic, etc., the temperature of the interface material is usually closer to the temperature of the low temperature side, so that when the water vapor in the air at the higher temperature side contacts the substrate at the lower temperature, it will condense to form small liquid droplets with poor fluidity on the surface, i.e., generate mist. In some particular environments, the presence of mist can have a number of adverse effects. For example, fog is generated on the windshield of an automobile, which affects the driving of the driver and increases the risk of traffic accidents; for another example, fog is generated on the plastic film of the plastic greenhouse, and can refract sunlight to affect the growth of crops in the greenhouse. Therefore, it is necessary to perform antifogging modification of the transparent substrate used in these environments.
Coating of aqueous antifog coatings is a common antifog modification method. Among them, the most commonly used water-based antifogging coating is hydrophilic acrylate or its copolymer, which has an antifogging effect by utilizing the absorption effect of the resin coating on the condensed moisture on the coating surface. However, although hydrophilic acrylate or its copolymer has an antifogging effect, its surface strength, surface scratch resistance, surface corrosion resistance and the like are generally not satisfactory, and particularly, for coating a transparent antifogging aqueous coating applied to the surface of a transparent window material, such as the surface of an automobile windshield, the surface of a plastic film of a plastic greenhouse and the like, it is required to have not only excellent antifogging performance but also good surface strength, surface scratch resistance, surface corrosion resistance and the like. Therefore, the invention aims to provide the water-based anti-fog coating with excellent performance, which not only has excellent anti-fog performance, but also has good surface strength, surface scratch resistance and surface corrosion resistance.
Disclosure of Invention
The invention aims to solve the technical problem that the surface strength, the surface scratch resistance and the surface corrosion resistance of the existing water-based antifogging coating are improved while the excellent antifogging performance is ensured.
Therefore, the inventor of the invention provides an aqueous antifogging coating, which comprises 80-100g of aqueous resin emulsion, 10-30g of cross-linking agent and 10-30g of antifogging modifier, and is characterized in that: the antifogging modifier is an organic siloxane compound with a star-shaped structure, and the organic siloxane compound with the star-shaped structure is prepared by addition reaction of octavinyl polysilsesquioxane shown as a formula (1) and polyether containing an epoxypropane chain and an epoxyethane chain shown as a formula (2). The center of the obtained star-shaped organic siloxane compound is a polysilsesquioxane structure, and eight polyether branched chains containing propylene oxide chains and ethylene oxide chains are uniformly distributed on all sides of the polysilsesquioxane structure.
The formula (1) is:
the formula (2) is:
wherein m is 3-15, preferably 5-10, n is 3-20, preferably 5-15;
the reaction formula is as follows:
wherein the aqueous resin emulsion is selected from one of aqueous polyurethane emulsion, aqueous acrylic resin emulsion and aqueous epoxy resin emulsion.
Further, the addition reaction is carried out in a solvent, wherein the solvent is selected from one or more of benzene, toluene, ethylene glycol monobutyl ether, ethyl acetate and tetrahydrofuran.
Further, the catalyst is selected from platinum, nickel, gold and other catalysts, and is preferably chloroplatinic acid. The amount of the catalyst used is 1 to 3wt% of the octavinyl polysilsesquioxane represented by formula (1).
Furthermore, in order to ensure that the organosiloxane compound with a star-shaped structure is obtained, the mol ratio of the octavinyl polysilsesquioxane shown in the formula (1) to the polyether containing the propylene oxide chain and the ethylene oxide chain shown in the formula (2) participating in the reaction is 1 (8-10), the reaction temperature is 60-100 ℃, and the reaction time is 3-6 h.
The anti-fog modifier developed by the inventor is added into the water-based anti-fog coating, so that the coating film layer has excellent anti-fog performance, and meanwhile, the water-based anti-fog coating has good surface strength, surface scratch resistance and surface corrosion resistance. In the antifogging modifier developed by the inventor, the octavinyl polysilsesquioxane is used as the core of a star-shaped structure, and the special physical properties of the cage polysilsesquioxane can be fully utilized. The cage type polysilsesquioxane is an inorganic core formed by a large number of silicon-oxygen frameworks connected by Si-O bonds alternately, the three-dimensional size of the cage type polysilsesquioxane is 1-3nm, the cage type polysilsesquioxane is a typical nano particle compound, is hydrophilic, is waterproof, has excellent comprehensive performance, and is particularly outstanding in the aspects of mechanical strength, scratch (or friction) resistance, corrosion resistance and the like. Can obviously improve the surface strength, the surface scratch resistance and the surface corrosion resistance of the water-based paint.
Meanwhile, the inventor considers that the polysilsesquioxane compound has poor wettability with the water-based paint and insufficient hydrophilic and antifogging properties, and carries out addition reaction on eight vinyl groups of the octavinyl polysilsesquioxane to graft polyether groups with low surface energy, hydrophilicity and wettability onto the polysilsesquioxane, so that the wettability of the polysilsesquioxane with the water-based paint is improved, and the antifogging property of the water-based paint is enhanced. Meanwhile, the eight vinyls of the octavinyl polysilsesquioxane are uniformly distributed on all sides of the core structure of the polysilsesquioxane, so that the final antifogging modifier is of a star-shaped structure, the star-shaped structure provides a microscopic physical structure space for the hydrophilic property and the water absorption of the coating, and the antifogging performance of the water-based coating is enhanced.
