Embodiment Construction

[0023] The specific implementation of the present invention will be further described below in conjunction with examples. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0024] The technical scheme of the present invention is:

[0025] A spray painting process for the plastic window of a sports bracelet includes the following steps:

[0026] 1) The first printing process: first mask the light-transmitting area on the back of the plastic window of the sports bracelet, and then print the back of the plastic window of the sports bracelet. After printing, the plastic windows of the sports bracelet are sequentially cured and cooled;

[0027] 2) Pre-treatment: On the assembly line, first mask and assemble the plastic window of the sports bracelet (shading the light-transmitting area on the back of the plastic window of the sports bracelet), and th...

Abstract

The invention discloses a painting technology for plastic windows of sports bracelets. The technology comprises steps as follows: 1) first-time printing treatment; 2) pretreatment; 3) first-time painting treatment; 4) second-time painting treatment; 5) second-time printing treatment; and 6) detection. With the painting technology, the performance of the plastic windows of the sports bracelets can be improved. Paint films formed on the plastic windows of the sports bracelets with the painting technology can have performance as follows: the front-side film layer thickness is 14 [mu]m+ / -2 [mu]m, the back-side film layer thickness is 20 [mu]m + / -5 [mu]m, the hardness is higher than or equal to 2 H, the RCA is higher than or equal to 175 g / 500 times, the linear wear resistance is higher than or equal to 750 g / 500 times, the alcohol wear resistance is higher than or equal to 500 g / 50 times, and the adhesive force is higher than or equal to 5 B.

Description

Technical field [0001] The invention relates to a spray painting process for a plastic window of a sports bracelet. Background technique [0002] After the plastic window of the sports bracelet is finished by injection molding, taking into account the poor surface hardness of the plastic window of the sports bracelet, in order to solve the problem of easy abrasion and scratches on the surface during use, the visual effect is higher, so the coating performance after painting is higher. Requirements, the current sports bracelet plastic window industry mostly adopts direct injection molding, which cannot meet the needs of use. Summary of the invention [0003] The purpose of the present invention is to provide a spray paint process for the plastic window of the sports bracelet, which can improve the performance of the plastic window of the sports bracelet. [0004] In order to achieve the above objective, the technical solution of the present invention is to design a spray painting pr...
