Method of laser engraving on the surface of uv electroplating glass products

Abstract

The invention discloses a method for carrying out laser carving on the surface of a UV electroplated glass product. The method comprises the following steps: (1) cleaning the surface of a glass product; (2) spraying electroplating priming paint on the cleaned surface of the glass product; (3) carrying out UV curing on the glass product covered by the electroplating priming paint; (4) carrying out vacuum coating on the glass product after the UV curing; (5) spraying intermediate paint on the surface of the vacuum coated layer; (6) carrying out secondary curing on the glass product covered by the intermediate paint; (7) carrying out laser carving on the surface of the glass product which has been processed in the step (6), removing the upper coating of the coated layer; (8) carrying out finish paint spraying and curing on the glass product which has been carved by laser. The method combines the present technologies of UV curing, vacuum electroplating, and laser carving to achieve carving on a glass product, and thus the processed glass product is wear-resistant, scratch-resistant, and solvent-resistant. Moreover, the patterns on the surface are stable and more three-dimensional hollow-out effect is achieved at the same time.

Description

technical field [0001] The invention belongs to the technical field of surface treatment and processing of glass products, in particular to a process and method for laser engraving on the surface of UV electroplated glass products to form a hollow effect. This method is especially suitable for cosmetic perfume bottles, aromatherapy bottles, wine glass bottle packaging, etc., as well as other decorative glass products. The text lines are extremely clear, the three-dimensional effect is strong, and the transparency and decoration of the glass are greatly improved. Background technique [0002] With the provision of people's quality of life, the packaging of daily necessities requires higher visual effects, especially cosmetic bottles, perfume bottles, aromatherapy bottles, wine packaging bottles, etc., all use glass products as their packaging. In order to have a better visual and aesthetic effect, it is most common to make glass bottles with a hollow effect. There are the f...

Problems solved by technology

There are the following ways to realize the surface of traditional hollowed-out glass products: (1) Sticker covering method, using stickers to cover the exposed areas first and then proceed to subsequent processing. The main process is generally: degreasing and decontamination of the processed surface Processing->sticker->coating->curing->heating->tearing paper, most of the processes are manually operated, with low efficiency, low product grade, and easy to produce defective products, especially in the process of stickers. Uniform standards, non-standard, imprecise, easy to produce jagged burrs on the edge of the pattern when tearing off the paper, in addition, due to the stickiness of the paper, it is easy to cause secondary pollution, and the lines of the pattern text cannot be made very fine due to the paper; (2) Screen printing and pad printing technology, when this technology is applied on the surface of UV electroplating glass products, the pattern and text have a certain feel, but the surface of the product to be operated must be flat, the arc is small, and it cannot be uneven. The temperature is 170-200 degrees during production. Left and right, the process has strong firmness, clear lines and smooth edges without burrs, and there are not too many restrictions on the surface of the processed products. The processed products are of high grade, the two-dimensional effect is excellent, and the cost is high; (3) Gold tracing Technology, the traditional gold tracing process uses real gold paste, which is expensive, pollutes a lot, and is not environmentally friendly. The temperature needs to be heated to 500-600°C during processing, which consumes a lot of energy. All countries have formulated corresponding laws and regulations to strictly prohibit serious pollution. The opening of enterprises requires the rectification of enterprises with serious pollution, and many products of this technology are also manually operated at this stage, and the color is basically a single gold series, and the product color is single
