Description

Technical Field

[0001] The present invention specifically relates to a method for preventing high-temperature gold from being oxidized on a glass surface. Background Art

[0002] Currently, it's common to see glassware with gilded surfaces on the market, some with complex designs and others with relatively simple ones. The gilding process involves hand-painting to achieve the desired design. The raw material used for gilding, glass gold water, often contains oxidizing or reducing metal compounds such as gold salts and bismuth salts. After high-temperature baking and storage for three to six months, oxidation can occur on the surface, affecting the product's appearance.

[0003] With the advancement of glass bottle production technology, customer demand for richer product appearances continues to increase, and deep processing of glass products is becoming increasingly popular. However, high-temperature gold paste gilding, as a glass gilding process, is subject to oxidation due to the unique environment. High-temperature gold paste creates a vibrant, three-dimensional luster on the glass surface, creating a high-quality texture. However, its oxidation resistance is poor in humid environments, making it unsuitable for deep processing and decorative production. The industry often uses low-temperature gilding and electroplating as alternatives. Currently, there is no high-temperature gilding (gilding) anti-oxidation process for deep processing of crystal glass materials. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a method for preventing gold from being oxidized at high temperatures on a glass surface. The method can effectively solve the above-mentioned problems.

[0008] S3: Stress relief by baking, use a 4-zone oven or a 4-zone standard oven, set the temperature to 300℃ for zone 1, 400℃ for zone 2, 500℃ for zone 3, and 480℃ for zone 4, and set the network speed to 8HZ;

[0009] S4: Use low-temperature varnish, dip the tracing brush into the low-temperature varnish, and paint the varnish according to the position of the gold paste. After painting, let it dry naturally;

[0010] S5: Low temperature baking, choose a low temperature standard baking oven, set the temperature to 140℃ for zone 1, 150℃ for zone 2, 150℃ for zone 3, and 150℃ for zone 4, and set the network speed to 15HZ.
