Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint, in particular to an oil cup coating slurry, a preparation method thereof and an oil cup. BACKGROUND

[0002] With the continuous improvement of people's living standards, most kitchens are equipped with range hoods. The kitchen can make the air containing oil fume discharged through the exhaust duct through the range hood, which can reduce the irritating smell in the kitchen, and the oil fume discharged through the range hood can reduce the oil fume inhaled by the human body, which is beneficial to the health of the body.

[0003] During the use of the range hood, the oil fume generated is taken away by the negative pressure generated by the high-speed rotation of the impeller. The filter screen and the inner cavity of the range hood store a large amount of oil, and finally flow into the oil collector, i.e. the oil cup. When the old oil in the oil cup accumulates to a certain amount, it needs to be disassembled and cleaned. The old oil at the bottom of the oil cup will condense into relatively stubborn sediments, which need to be cleaned with a strong alkaline cleaning agent, which is time-consuming and laborious, and the alkaline cleaning agent can also cause certain harm to the skin. In addition, the organic components in the oil cup are very numerous, and bacteria can easily breed over time. At present, a large number of resin oil cups are still used in the industry, and many oil cups are made of PC material, so the surface hardness is very low. Therefore, it is necessary to develop an oil cup that is antibacterial, super hard and easy to clean.

[0039] To make the objectives, technical solutions and advantages of the application clearer, the technical solutions in the embodiments of the application will be described below in conjunction with the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. The components of the embodiments of the application can be arranged and designed in various different configurations.

[0040] It is to be understood that the terminology used herein such as first and second, and the like, is merely intended to differentiate one entity or operation from another entity or operation, without necessarily requiring or implying any actual such relationship or order between such entities or operations. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0041] The first aspect of the present application provides an oil cup coating slurry comprising a thermosetting resin, a hydroxy ketone compound, a photoinitiator, a filler, an additive, and a solvent.

[0042] The additive comprises an antifouling aid, a wetting agent, a leveling agent, and an antibacterial aid.

[0043] The oil cup coating slurry provided by the present application rapidly generates high-activity free radicals after photolysis of the photoinitiator, which effectively initiates the curing reaction of the thermosetting resin to form a stable three-dimensional network structure, thereby significantly improving the hardness of the coating. Secondly, the hydroxy ketone compound becomes extremely active in its chemical properties under the catalysis of the photoinitiator, and can actively participate in the curing process of the thermosetting resin to react with the resin to generate heterocyclic compounds, which not only enhances the crosslinking density of the coating, but also further improves the surface hardness of the oil cup coating. In addition, the filler is uniformly dispersed in the coating slurry and effectively fills the pores of the coating during the curing process to form a film, thereby improving the hardness and compactness of the entire film layer. The addition of such a filler not only enhances the physical properties of the coating, but also helps to improve the scratch resistance of the coating. At the same time, the additives in the slurry, such as the antifouling aid, the wetting agent, the leveling agent, and the antibacterial aid, synergistically act with the base ingredients to endow the coating with excellent antibacterial properties and self-cleaning ability, allowing it to maintain high hardness while also having good hygiene and maintenance characteristics.

[0044] Further, the oil cup coating slurry comprises, by weight fraction, 20-50 parts of a thermosetting resin, 15-40 parts of a hydroxy ketone compound, 1-3 parts of a photoinitiator, 5-10 parts of a filler, 3.8-7.5 parts of an additive, and 40-60 parts of a solvent.

[0045] The additive comprises 0.5-1.0 parts of an antifouling aid, 0.2-1.0 parts of a wetting agent, 0.1-0.5 parts of a leveling agent, and 3-5 parts of an antibacterial aid.

The fraction of the filler can be 5 parts, 6 parts, 7 parts, 8 parts, 9 parts or 10 parts, to provide the filling effect and improve the physical properties required by the coating. The total fraction of the additives can be 3.8 parts, 4 parts, 5 parts, 6 parts, 7 parts or 7.5 parts, or any value within the range of 3.8-7.5 parts.

[0047] The fraction of the solvent can be 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, or any value within the range of 40-60 parts, to adjust the viscosity and drying rate of the coating slurry. In the subdivision of the additives, the fraction of the stain-resistant aid can be 0.5 parts, 0.6 parts, 0.7 parts, 0.8 parts or 1.0 parts, the fraction of the wetting agent can be 0.2 parts, 0.4 parts, 0.6 parts, 0.8 parts or 1.0 parts, the fraction of the leveling agent can be 0.1 parts, 0.2 parts, 0.3 parts, 0.4 parts or 0.5 parts, and the fraction of the antibacterial aid can be 3 parts, 4 parts or 5 parts.

[0048] Further, the oil cup coating slurry comprises, according to the weight fraction, 25-45 parts of thermosetting resin, 15-35 parts of hydroxy ketone compound, 1-3 parts of photoinitiator, 5-10 parts of filler, 4.3-7.5 parts of additives and 45-55 parts of solvent;

[0049] The additives include 0.6-1.0 parts of stain-resistant aid, 0.6-1.0 parts of wetting agent, 0.1-0.5 parts of leveling agent and 3-5 parts of antibacterial aid.

[0050] Further, the oil cup coating slurry comprises, according to the weight fraction, 30-40 parts of thermosetting resin, 20-30 parts of hydroxy ketone compound, 2-3 parts of photoinitiator, 5-10 parts of filler, 4.6-7.3 parts of additives and 45-55 parts of solvent;

[0051] The additives include 0.8-1.0 parts of stain-resistant aid, 0.7-0.8 parts of wetting agent, 0.1-0.5 parts of leveling agent and 3-5 parts of antibacterial aid.

[0052] Further, the thermosetting resin comprises at least one of polyacrylic resin, epoxy resin, polyester resin, vinyl ester resin, bismaleimide resin, polyimide resin and cyanate ester resin.

[0053] The thermosetting resin as the base resin of the oil cup coating paste provides a series of advantages, including the formation of a hard and wear-resistant three-dimensional network structure after curing, which not only enhances the scratch resistance and wear resistance of the oil cup, but also endows the coating with excellent chemical stability and thermal stability, enabling it to resist the erosion of oil and cleaning agents while maintaining its shape and performance at high temperatures. The high mechanical strength and impact resistance of the thermosetting resin ensure the durability of the oil cup in daily use. In addition, the electrical insulation performance of the thermosetting resin also provides additional safety for users.

[0054] Preferably, the hydroxy ketone compound includes at least one of hexahydroxy ketone, penta-hydroxy ketone, tetra-hydroxy ketone, tri-hydroxy ketone and di-hydroxy acetone.

[0055] The hydroxy ketone compound, due to the presence of multiple hydroxyl groups, can form hydrogen bonds or other forms of interaction with the active groups in the thermosetting resin, enhancing the cohesion and cross-linking density of the coating. This coordination also helps to improve the rheological properties of the coating, making the oil cup coating paste easier to apply during construction, while forming a uniform and defect-free surface during curing. The addition of the hydroxy ketone compound can also adjust the curing rate and final mechanical properties of the coating.

[0056] Preferably, the photoinitiator includes at least one of phenyl bis(2,4,6-trimethylbenzoyl) phosphine oxide, bisacyl phosphine oxide, carbazyl acyl phosphine oxide, diphenyl phosphine oxide and diaryl phosphine oxide.

[0057] The above-mentioned photoinitiator has greater absorption in the ultraviolet and visible light regions, and after photolysis, it produces highly active free radicals that can initiate curing more effectively than other photoinitiators. The above-mentioned initiator hardly yellow after curing and long-term light radiation, has a bleaching effect on light, and the rays can penetrate the coating, allowing the thick film to be completely cured.

[0058] During the photocuring process, the above-mentioned photoinitiator absorbs light energy and changes to an excited state under the irradiation of ultraviolet or visible light. The excited state of the photoinitiator has high chemical activity and can efficiently decompose to produce free radicals or other active intermediates. These free radicals or intermediates rapidly react with reactive groups in the thermosetting resin, such as epoxy groups or unsaturated carbon-carbon double bonds, initiating and accelerating the entire cross-linking and curing process. The hydroxy ketone compound, due to the presence of multiple hydroxyl groups, can participate in the cross-linking reaction and form hydrogen bonds with the thermosetting resin, enhancing the cohesion and mechanical properties of the coating.

[0059] Further, the filler is an ultra-fine high-hardness ceramic powder.

[0060] Preferably, the brand of the anti-fouling assistant includes KY1203 and / or DAC-HP.

[0061] Preferably, the brand of the wetting agent includes at least one of MOK-5011, MOK-5027 and MOK-5035.

[0062] Preferably, the brand of the leveling agent includes at least one of MOK-2021, MOK-2024 and MOK-2100.

[0063] Further, the anti-bacterial assistant includes nano-zinc oxide.

[0064] Preferably, the brand of the nano-zinc oxide includes at least one of CS2132PA, CS1952, SHL-CRE1021 and HSL-PA-2021.

[0065] Preferably, the solvent includes at least one of propylene glycol methyl ether, butyl acetate, isobutyl alcohol, methyl isobutyl ketone and ethyl acetate.

[0066] The second aspect of the present application provides a preparation method of the oil cup coating slurry, comprising the following steps:

[0067] A. In a stirring state, add the thermosetting resin, the hydroxy ketone compound and the photoinitiator into the solvent and mix uniformly to obtain a slurry semi-product;

[0068] B. Continue to add the additive and the filler into the slurry semi-product and mix uniformly, and finally filter or vacuum degassing to obtain the oil cup coating slurry.

[0069] The preparation method provided by the present application has the characteristics of simple operation, high efficiency and easy to scale production, and is very suitable for industrial application. The oil cup coating slurry prepared by this method not only can ensure the high performance of the coating, but also can meet the demand of large-scale production, reduce the production cost and improve the market competitiveness.

[0070] Further, in step B, the filtering is performed using a 200-mesh screen.

[0071] Preferably, the mixing mode includes stirring.

[0072] Preferably, the stirring speed is 400-600 rpm.

[0073] The third aspect of the present application provides an oil cup comprising an oil cup body and an oil cup coating attached to the surface of the oil cup body.

[0074] The oil cup coating is prepared using the oil cup coating slurry of the first aspect.
