Description

[0002] As people's living standards improve, they demand cookware that is not only practical but also aesthetically pleasing and personalized. Aluminum alloy cookware is popular among consumers for its lightweight, excellent thermal conductivity, and corrosion resistance. Printing technology, a key tool for enhancing the aesthetics of cookware, has seen rapid development in recent years.

[0003] At present, the printing technology of aluminum alloy cookware mainly includes heat transfer printing, electrophoretic coating, 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 coating 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 evenly spray the paint 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 paint, 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 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.

[0158]

[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 a scouring pad around the grinding head of the tester. Set the number of frictions to 5000, the grinding head stroke to 10 cm, and the speed to 60 times / minute. Repeat the grinding head on the middle layer of the cookware for the set number of times.

[0166] Use a microscope or high-precision measuring tool to measure the difference in coating thickness before and after wear, and record the amount of wear. Scratch depths of less than 0.01mm are considered mild wear, indicating excellent wear resistance. Scratch depths between 0.01mm and 0.05mm are considered moderate wear, indicating moderate wear resistance. Scratch depths exceeding 0.05mm are considered severe wear, indicating poor wear resistance.

[0167] Test the cookware's scratch resistance: Use the RW-7831A cookware coating scratch resistance tester. Apply 8 psi of air pressure to the piston through the air valve. Press the pen tip of the tester onto the cookware coating, ensuring full contact. Start the tester and use the ballpoint pen tip to scratch a 4-5 cm 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 interlayer was considered to have excellent scratch resistance. If the depth was between 0.01 mm and 0.05 mm, the interlayer was considered to have moderate scratch resistance. If the depth exceeded 0.05 mm, the interlayer was considered to have poor scratch resistance.

[0169] To test the color fastness and fastness of the printed layer: Place the pot to be tested on the test table of the wet friction fastness tester, ensuring that the printed part is facing up. Evenly wet a standardized friction cloth with water to simulate daily stains. Fix the friction cloth to the friction head of the friction tester and set the friction count to 500 times, the friction pressure to 10N, and the friction speed to 60 times / minute. Rub the wet cloth back and forth on the printed part. 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 tissue and analyze the changes in grayscale values ​​to quantify the degree of color transfer. No color transfer or less than 1% transfer indicates excellent print fixation, 1% to 5% indicates medium print fixation, and greater than 5% indicates poor print fixation.

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

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