Description

Technical Field

[0001] The invention relates to the technical field of coatings, and in particular to an oil cup coating slurry and a preparation method thereof, and an oil cup. Background Art

[0002] With the continuous improvement of people's living standards, most kitchens are equipped with range hoods. The range hood can allow the air with oil smoke to be discharged from the kitchen through the exhaust duct, which can reduce the choking smell in the kitchen. In addition, exhausting oil smoke through the range hood can reduce the oil smoke inhaled by the human body, which is beneficial to the health of the body.

[0003] During the use of the range hood, the negative pressure generated by the high-speed rotation of the impeller takes away the generated oil smoke. As a result, the filter and inner cavity of the range hood will store a large amount of grease, which will eventually flow into the oil collector - the oil cup. When the old oil in the oil cup accumulates to a certain amount, it must be removed for cleaning. The old oil at the bottom of the oil cup will condense into a relatively stubborn sediment, which requires a very strong alkaline detergent to be cleaned, which is time-consuming and labor-intensive. At the same time, the alkaline detergent will also cause certain damage to human skin. In addition, there are many organic components in the oil cup, which is very easy to breed bacteria over time. At present, there are still a large number of resin oil cups in the industry. Many oil cups are made of PC material with a very low surface hardness. Therefore, it is very necessary to develop an antibacterial, super-hard and easy-to-clean oil cup.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in combination with the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, but not all of the embodiments. The components of the embodiment of the present invention can be arranged and designed in various different configurations.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] A first aspect of the present invention provides an oil cup coating slurry comprising a thermosetting resin, a hydroxyketone compound, a photoinitiator, a filler, an additive and a solvent; The additives include antifouling agents, wetting agents, leveling agents and antibacterial agents.

[0033] The oil cup coating slurry provided by the present invention, the photoinitiator quickly generates highly active free radicals after photolysis, and these free radicals effectively trigger the curing reaction of the thermosetting resin to form a stable three-dimensional network structure, thereby significantly improving the hardness of the coating. Secondly, under the catalysis of the photoinitiator, the chemical properties of the hydroxyketone compound become extremely active, and it can actively participate in the curing process of the thermosetting resin, reacting 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 evenly dispersed in the coating slurry, and effectively fills the pores of the coating during the curing film forming process, thereby improving the hardness and density of the entire film layer. The addition of this 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, additives in the slurry, such as antifouling additives, wetting agents, leveling agents and antibacterial additives, synergistically act with the basic components to give the coating excellent antibacterial properties and self-cleaning ability, so that it has good hygiene and maintenance characteristics while maintaining high hardness.

[0034] Furthermore, the oil cup coating slurry comprises, by weight, 20 to 50 parts of a thermosetting resin, 15 to 40 parts of a hydroxyketone compound, 1 to 3 parts of a photoinitiator, 5 to 10 parts of a filler, 3.8 to 7.5 parts of an additive, and 40 to 60 parts of a solvent; The additives include 0.5-1.0 parts of antifouling additives, 0.2-1.0 parts of wetting agents, 0.1-0.5 parts of leveling agents and 3-5 parts of antibacterial additives.

[0035] Typically but not limiting, the formula of the oil cup coating slurry can be precisely formulated according to the weight percentage, wherein the percentage of thermosetting resin can be 20, 22, 25, 30, 40, 45 or 50, or any value in the range of 20 to 50; the percentage of hydroxyketone compound can be 15, 20, 25, 30, 35, 38 or 40, or any value in the range of 15 to 40; the percentage of photoinitiator can be 1, 1.5, 2 or 3 to ensure that there are enough active ingredients to initiate the polymerization reaction during the photocuring process. The percentage of filler can be 5, 6, 7, 8, 9 or 10 to provide the required filling effect and improve the physical properties of the coating. The total percentage of additives can be 3.8, 4, 5, 6, 7 or 7.5, or any value in the range of 3.8 to 7.5.

[0036] The amount of solvent can be 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, or any value within the range of 40 to 60 parts to adjust the viscosity and drying rate of the coating slurry. In the subdivision of the additives, the amount of antifouling agent can be 0.5 parts, 0.6 parts, 0.7 parts, 0.8 parts or 1.0 parts, the amount of wetting agent can be 0.2 parts, 0.4 parts, 0.6 parts, 0.8 parts or 1.0 parts, the amount of leveling agent can be 0.1 parts, 0.2 parts, 0.3 parts, 0.4 parts or 0.5 parts, and the amount of antibacterial agent can be 3 parts, 4 parts or 5 parts.

[0037] Furthermore, the oil cup coating slurry comprises, by weight, 25 to 45 parts of a thermosetting resin, 15 to 35 parts of a hydroxyketone compound, 1 to 3 parts of a photoinitiator, 5 to 10 parts of a filler, 4.3 to 7.5 parts of an additive, and 45 to 55 parts of a solvent; The additives include 0.6-1.0 parts of antifouling agent, 0.6-1.0 parts of wetting agent, 0.1-0.5 parts of leveling agent and 3-5 parts of antibacterial agent.

[0038] Furthermore, the oil cup coating slurry comprises, by weight, 30 to 40 parts of a thermosetting resin, 20 to 30 parts of a hydroxyketone compound, 2 to 3 parts of a photoinitiator, 5 to 10 parts of a filler, 4.6 to 7.3 parts of an additive, and 45 to 55 parts of a solvent; The additives include 0.8-1.0 parts of antifouling additives, 0.7-0.8 parts of wetting agents, 0.1-0.5 parts of leveling agents and 3-5 parts of antibacterial additives.

[0039] Furthermore, the thermosetting resin includes at least one of polyacrylic resin, epoxy resin, polyester resin, vinyl ester resin, bismaleimide resin, polyimide resin and cyanate ester resin.

[0040] As the base resin of the oil cup coating slurry, the thermosetting resin provides a series of advantages, including the hard and wear-resistant three-dimensional network structure formed after curing, which not only enhances the scratch and wear resistance of the oil cup, but also gives the coating excellent chemical and thermal stability, enabling it to resist the corrosion of grease and detergents 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 properties of the thermosetting resin also provide additional safety for users.

[0041] Preferably, the hydroxyketone compound includes at least one of hexahydroxyketone, pentahydroxyketone, tetrahydroxyketone, trihydroxyketone and dihydroxyacetone.

[0042] Hydroxyl ketone compounds contain multiple hydroxyl groups, which can form hydrogen bonds or other forms of interactions with active groups in thermosetting resins, thereby enhancing the cohesion and crosslinking density of the coating. This coordination relationship also helps to improve the rheological properties of the coating, making the oil cup coating slurry easier to apply during construction, and forming a uniform and defect-free surface during the curing process. The addition of hydroxy ketone compounds can also adjust the curing rate and final mechanical properties of the coating.

[0043] Preferably, the photoinitiator comprises at least one of phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, bisacylphosphine oxide, carbazolylacylphosphine oxide, diphenylphosphine oxide and diarylphosphine oxide.

[0044] The above-mentioned photoinitiator has greater absorption in the ultraviolet and visible light regions. After photolysis, it produces free radicals with high initiation activity, which can initiate curing more effectively than other photoinitiators. The above-mentioned initiator hardly turns yellow after curing and under long-term light radiation. It has a bleaching effect on light. The rays can penetrate the coating, and the thick film can be thoroughly cured.

[0045] During the photocuring process, the above-mentioned photoinitiator absorbs light energy and transforms into an excited state under the irradiation of ultraviolet light or visible light. The excited photoinitiator has high chemical activity and can efficiently decompose to produce free radicals or other active intermediates. These free radicals or intermediates quickly react with reactive groups in thermosetting resins, such as epoxy groups or unsaturated carbon-carbon double bonds, to start and accelerate the entire cross-linking curing process. Hydroxyketone compounds can participate in the cross-linking reaction because they contain multiple hydroxyl groups, forming hydrogen bonds with thermosetting resins, and enhancing the cohesion and mechanical properties of the coating.

[0046] Furthermore, the filler is ultrafine high-hardness ceramic powder.

[0047] Preferably, the brands of the antifouling agent include KY1203 and / or DAC-HP.

[0048] Preferably, the brand of the wetting agent includes at least one of MOK-5011, MOK-5027 and MOK-5035.

[0049] Preferably, the grade of the leveling agent includes at least one of MOK-2021, MOK-2024 and MOK-2100.

[0050] Furthermore, the antibacterial auxiliary agent includes nano zinc oxide.

[0051] Preferably, the brand of the nano zinc oxide includes at least one of CS2132PA, CS1952, SHL-CRE1021 and HSL-PA-2021.

[0052] Preferably, the solvent includes at least one of propylene glycol methyl ether, butyl acetate, isobutyl alcohol, methyl isobutyl ketone and ethyl acetate.

[0053] The second aspect of the present invention provides a method for preparing the oil cup coating slurry, comprising the following steps: A. Under stirring, add thermosetting resin, hydroxy ketone compound and photoinitiator into the solvent and mix them evenly to obtain a slurry semi-finished product; B. Add additives and fillers to the semi-finished slurry and mix them evenly, and finally filter or vacuum degas to obtain the oil cup coating slurry.

[0054] The preparation method provided by the present invention has the characteristics of simple operation, high efficiency, and easy large-scale production, and is very suitable for industrial application. The oil cup coating slurry prepared by this method can not only ensure the high performance of the coating, but also meet the needs of large-scale production, reduce production costs, and improve market competitiveness.

[0055] Furthermore, in step B, a 200-mesh sieve is used for the filtration.

[0056] Preferably, the mixing method includes stirring.

[0057] Preferably, the stirring speed is 400-600 rpm.

[0058] A third aspect of the present invention provides an oil cup including an oil cup body and an oil cup coating attached to a surface of the oil cup body; Wherein, the oil cup coating is prepared using the oil cup coating slurry described in the first aspect.

[0059] The oil cup provided by the present invention, in view of the advantages of the above-mentioned oil cup coating slurry, has the prepared oil cup with superhard properties and antibacterial and easy-to-clean properties, thereby solving the problems of the oil cup being antibacterial, difficult to clean and easy to scratch on the surface, extending the life of the oil cup, providing users with an oil cup that is both beautiful and practical, and greatly improving the quality and user experience of kitchen supplies.

After spraying, it was allowed to stand at 23°C ± 2°C for 2-3 minutes for leveling, and then heated at 70°C for 5 minutes. At the same time, the ultraviolet energy density was 500-700 MJ / m 2 , irradiate for 10~15s to cure the coating, and then let it stand for 1h for performance testing.

[0104] Performance tests include film thickness, hardness, adhesion, water drop angle, oil drop angle, oily pen stroke line, wipeability and antibacterial performance tests.

[0105] The film thickness test is carried out according to the provisions of GB T 13452.2-2008; The hardness test is carried out according to the provisions of GB / T 6739-2006; Adhesion test is carried out according to the provisions of GB / T 6739-2006; The water drop angle test is carried out according to the provisions of GB / T 30693-2014; The oil drop angle test is carried out according to the provisions of GB / T 30693-2014, replacing water with n-hexadecane; Oil-based pen line test: Use a Zebra brand oil-based pen to draw a 5cm long straight line on the coating surface. The oil-based pen shrinks and breaks. For the wiping test, use a Zebra brand oil pen to draw a 5cm long straight line on the coating surface. After 5 seconds, wipe it 3 to 5 times with a tissue paper to erase the notes. The antibacterial test was carried out according to the provisions of GB_T21866-2008.

[0106] The test data are recorded in Table 1. The hardness before treatment in Table 1 refers to the body hardness of the PC oil cup.

[0107] Table 1

[0108] As can be seen from Table 1, in Examples 1 to 9, the addition of ultrafine ceramic powder significantly improves the surface hardness; the antifouling agent makes the surface easy to clean and the oil stains are not easy to adhere; the addition of antibacterial agent nano zinc oxide also makes the surface have super strong antibacterial properties to ensure safety and health; Comparative Example 1 is compared with Example 1, the adhesion of the coating is significantly reduced due to the lack of photoinitiator; Comparative Example 2 is compared with Example 1, the adhesion of the coating is significantly reduced due to the lack of photoinitiator; Comparative Example 1 is compared with Example 1, the surface hardness of the coating is significantly reduced due to the lack of ultra-high hardness ceramic powder; Comparative Example 3 is compared with Example 1, the antifouling agent is lacking, the coating has no easy cleaning performance, and the oil stains are difficult to wipe off; Comparative Example 4 is compared with Example 1, there is no antibacterial nano zinc oxide, and the antibacterial property of the coating is 0; Comparative Example 5 is compared with Example 1, and the pencil hardness of the coating is significantly reduced by replacing other hardening materials; Comparative Example 6 is compared with Example 1, and the performance of ordinary commercially available hardening liquid is much worse.
