Description

Technical Field

[0001] The present invention relates to the technical field of grease cleaning, and in particular to a super-wear-resistant and easy-to-clean hardened coating, a preparation method thereof, and an application thereof. 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 containing oil smoke to be discharged from the kitchen through the exhaust duct, which can reduce the choking smell in the kitchen. In addition, the exhaust of 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 use, the negative pressure generated by the high-speed rotation of the impeller draws away the fumes, causing a large amount of grease to accumulate in the filter and inner cavity of the range hood, eventually flowing into the oil cup. When the old oil in the oil cup reaches a certain level, it must be removed and cleaned. However, the accumulated old grease at the bottom of the oil cup will solidify into a stubborn deposit that requires a highly alkaline detergent to remove, which is time-consuming and labor-intensive. Alkaline detergents can also cause some damage to human skin.

[0004] At present, resin oil cups are still widely used in the industry, and the oil cups are frequently cleaned during use. Therefore, there is an urgent need for a super wear-resistant and easy-to-clean hardened coating and its preparation method and application. Summary of the Invention

[0005] The present invention provides, on one hand, a super-wear-resistant, easy-to-clean hardened coating, which enables the oil cup to have both super-wear-resistant properties and easy-to-clean properties, thereby solving the problems of easy cleaning and an extremely long service life of the oil cup.

[0051] 3. Application

[0052] A method for preparing a super wear-resistant and easy-to-clean hardened coating for cleaning grease on PC materials.

[0053] IV. Experiment

[0054] The preparation method is the same as that of Example 1-4 and Comparative Example 1-2, except that the types and amounts of raw materials are adjusted. The types and amounts of each raw material are shown in Table 1:

[0055] Table 1 Types, amounts and experimental conditions of various raw materials

[0056]

[0057]

[0058] The ultra-wear-resistant and easy-to-clean hardened coatings prepared in Examples 1-4 were sprayed onto a transparent PC substrate (cleaned with isopropyl alcohol, degreased, and free of static electricity). The film properties were measured after UV curing. The curing conditions are shown in Table 2, and the film properties are shown in Table 3.

[0059] Table 2 Curing conditions

[0060] project Process Require 1 spray gun 0.2~0.6MPA, 23℃±2℃, 55±5%RH 2 Leveling 23℃±2℃, let stand for 2-3 minutes 3 heating 70℃,5min 4 UV curing 500-700 MJ / M, time 10-15 seconds 5 test After curing, let it stand for 1 hour before testing

[0061] Table 3 Performance test results

[0062]

[0063] In Comparative Example 1, no antifouling agent was added, and there was no steel wool resistance at all, resulting in many scratches on the surface and failure in the steel wool resistance test.

[0064] In Comparative Example 2, no high-hardness wear-resistant filler was added. Although the material had anti-fouling properties, its steel wool resistance was very poor.

[0065] It can be seen from Table 3 that the super wear-resistant and easy-to-clean hardened coatings prepared in Examples 1-4 have excellent wear resistance and high adhesion effect, and are also very easy to clean.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
