Description

Technical Field

[0002] As people's living standards improve, they are looking for cookware that is not only practical, but also beautiful and personalized. Aluminum alloy cookware is popular among consumers because of its light weight, good thermal conductivity, and corrosion resistance. Printing technology, as an important means to improve the appearance of cookware, has developed rapidly in recent years.

[0003] At present, the printing technology of aluminum alloy cookware mainly includes heat transfer printing, electrophoretic painting, spraying and other methods. Among them, heat transfer printing transfers the pattern from the transfer paper to the surface of the cookware by heating. Although the operation is simple and efficient, the durability and wear resistance of the pattern are insufficient; electrophoretic painting has the advantages of uniform coating, strong adhesion and corrosion resistance, but the cost is high and the process is complicated; spraying uses spraying equipment to spray the paint evenly on the surface of the cookware to form a protective layer and a decorative layer, but the coating quality is greatly affected by the operating technology and the quality of the coating, especially the bonding with the surface of the pot body is poor and the coating is easy to fall off; if the surface properties of the pot body are changed, the wear resistance of the cookware will be affected.

[0004] Therefore, there is a need for a printed cookware that can meet aesthetic needs, does not affect the thermal conductivity and wear resistance of the cookware, and has a low cost. Summary of the invention

[0156] Specifically, the types and amounts of reagents added in Examples 1 to 5 and Comparative Examples 1 to 4 are shown in Tables 1 to 3.

[0160]

[0161]

[0162] Table 3 Types of reagents added in Comparative Examples 1 to 4

[0163]

[0164] It should be noted that the "middle layer ratio" in Table 2 and Table 3 refers to the mass ratio of the middle layer to the total printing layer in the printing layer.

[0165] Test the wear resistance of the cookware: Place the cookware to be tested on the test bench of the cookware coating wear resistance tester, wrap the scouring pad on the grinding head of the tester, set the number of frictions to 5000 times, the grinding head stroke to 10 cm, and the speed to 60 times / minute, and let the grinding head rub the middle layer of the cookware repeatedly for the set number of times;

[0166] Use a microscope or high-precision measuring tool to measure the thickness difference before and after coating wear and record the amount of wear. Scratch depth below 0.01mm is considered slight wear with excellent wear resistance, scratch depth between 0.01mm and 0.05mm is considered moderate wear with moderate wear resistance, and scratch depth exceeding 0.05mm is considered severe wear with poor wear resistance.

[0167] Test the scratch resistance of the cookware: Use the RW-7831A cookware coating scratch resistance tester, apply 8psi air pressure to the piston through the air valve, press the pen core of the tester onto the cookware coating, ensure full contact, start the tester, and let the ballpoint pen tip draw a 4-5cm long line on the coating;

[0168] The maximum depth of the scratch was measured using a microscope. If the scratch depth was less than 0.01 mm, the scratch resistance of the intermediate layer was considered excellent, if the depth was between 0.01 mm and 0.05 mm, the scratch resistance of the intermediate layer was considered medium, and if the depth exceeded 0.05 mm, the scratch resistance of the intermediate layer was considered poor.

[0169] Test the color fixation and fastness of the printed layer: Place the pot to be tested on the test table of the wet friction fastness tester, make sure the printed part is facing up, use water to simulate daily stains, evenly wet the standardized friction cloth, fix the friction cloth on the friction head of the friction tester, set the number of frictions to 500 times, the friction pressure to 10N, and the friction speed to 60 times / minute, and rub the wet cloth back and forth on the print. After the friction is completed, remove the pot and gently wipe the printed part with a white paper towel;

[0170] Use a grayscale scanner to scan the paper towel and analyze the change in grayscale value to quantify the degree of color transfer. No color transfer or less than 1% transfer is excellent printing fixation, 1% to 5% is medium printing fixation, and more than 5% is poor printing fixation;

[0171] Use a microscope or high-resolution camera to photograph the printed part before and after the test, and use image analysis software to evaluate the degree of wear. If the wear area is less than 5%, the print fastness is excellent, 5% to 15% is medium, and more than 15% is poor.

[0172] The test results are shown in Table 4:
