Problems solved by technology

For traditional watches, the scales and numbers on the dial are directly printed. After the dial is painted, due to long-term exposure to sunlight, it is easy to cause aging and discoloration of the paint layer. In severe cases, the paint layer will peel off and affect the use of the watch. Life, and does not have a three-dimensional effect; there are also scales that are inlaid, which has a three-dimensional effect, but it is easy to cause the scale to fall, affecting the reliability of the dial

Embodiment 1

[0029] A manufacturing process for a three-dimensional watch dial, comprising the following steps:

[0030] (1) Engraving: use laser to engrave grooves on the scale and number positions of the watch dial;

[0031] (2) Filling: fill the engraved groove with ink;

[0032] (3) Curing: The ink is thermally cured to obtain a three-dimensional watch dial.

[0033] In the step (1), the parameters of the laser engraving are: the motor power is 40W, the focal length is 25mm, and the cross section of the groove formed after laser engraving is in the shape of "凵".

[0034] In the step (3), the thermal curing temperature is 150° C. and the time is 10 minutes.

[0035] In the step (2), the ink includes the following raw materials in parts by weight: 50 parts of adhesive resin, 15 parts of inorganic filler, 5 parts of curing agent, 4 parts of thermal expansion microspheres, 4 parts of thickener, 0.5 part of leveling agent , 0.4 parts of defoamer, 1 part of dispersant, 1.5 parts of film-f...

Embodiment 2

[0043] The difference between this embodiment and the above-mentioned embodiment 1 is:

[0044] In the step (1), the parameters of the laser engraving are: the motor power is 50W, the focal length is 28mm, and the cross section of the groove formed after laser engraving is in an inverted "convex" shape.

[0045] In the step (3), the thermal curing temperature is 160° C. and the time is 8 minutes.

[0046] In the step (2), the ink includes the following raw materials in parts by weight: 55 parts of adhesive resin, 18 parts of inorganic filler, 8 parts of curing agent, 5 parts of thermal expansion microspheres, 5 parts of thickener, 0.8 parts of leveling agent , 0.5 parts of defoamer, 1.5 parts of dispersant, 1.8 parts of film-forming aid, 12 parts of inorganic pigment, and 15 parts of solvent.

[0047] The binder resin is a mixture composed of epoxy resin, alkyd resin and polyester resin in a weight ratio of 2.5:0.8:1; the inorganic filler is nano titanium dioxide.

[0048] T...

Embodiment 3

[0053] The difference between this embodiment and the above-mentioned embodiment 1 is:

[0054] In the step (1), the parameters of the laser engraving are: the motor power is 60W, the focal length is 30mm, and the cross section of the groove formed after laser engraving is in an inverted "convex" shape.

[0055] In the step (3), the thermal curing temperature is 180° C. and the time is 5 minutes.

[0056] In the step (2), the ink includes the following raw materials in parts by weight: 60 parts of adhesive resin, 20 parts of inorganic filler, 10 parts of curing agent, 6 parts of thermal expansion microspheres, 6 parts of thickener, 1 part of leveling agent , 0.6 parts of defoamer, 2 parts of dispersant, 2 parts of film-forming aid, 15 parts of inorganic pigment, and 20 parts of solvent.

[0057] The binder resin is a mixture of epoxy resin, alkyd resin and polyester resin in a weight ratio of 3:1:1; the inorganic filler is nano silicon dioxide.

[0058] The curing agent is i...

Abstract

The invention relates to the technical field of watch dial plates, in particular to a stereoscopic watch dial plate and a manufacturing process thereof. The manufacturing process includes the following steps: (1), carrying out engraving; specifically, engraving grooves in a scale and number positions of a watch dial plate through lasers; (2), carrying out filling; to be specific, filling the engraved grooves with ink; and (3) carrying out curing; to be specific, carrying out heat curing on the ink to obtain a stereoscopic watch dial plate. According to the manufacturing process, the scales andthe numbers are engraved firstly and then the ink is filled, so that the display of the dial plate has a three-dimensional effect; the paint layer is not easy to peel off, the reliability of the dialplate is better, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of watch dials, in particular to a three-dimensional watch dial and a manufacturing process thereof. Background technique [0002] China is the world's largest watch producer. China's watch manufacturing industry has gradually formed a clustered development structure with small and medium-sized enterprises as the main body. Private enterprises and foreign-funded enterprises have expanded rapidly (accounting for more than 70% of the total number of enterprises). and other six major producing areas. The reason why China's watch manufacturing industry has developed so rapidly is that it has seized the opportunity of the rise of quartz watches and electronic watches, and even threatened the Swiss high-end mechanical watch market. [0003] With the development of modernization, the decorations used by people in daily life are becoming more and more technological. Watches are common accessories for people, and t...
