Preparation method of mobile phone backboard with thermosensitive color-changing patterns

Abstract

The invention discloses a preparation method of a mobile phone backboard with thermosensitive color-changing patterns. The preparation method comprises the following steps: manufacturing a forming base material; polishing, grinding and cleaning the formed base material; preparing a pattern area; processing a frosted area; coating and processing the gradient thermosensitive color-changing layer; preparing a texture layer; preparing a hardened layer; preparing a metal electroplated layer; preparing a cover bottom layer; cleaning and drying. The texture pattern and the logo pattern are coated with the first thermosensitive color-changing ink and the second thermosensitive color-changing ink respectively, so that the appearance effect that the patterns on the mobile phone backboard change color gradually from outside to the center position is achieved, and the first thermosensitive color-changing ink and the second thermosensitive color-changing ink change color along with the change of temperature; the texture pattern and the logo pattern are convertible, the appearance effect of the mobile phone backboard is improved, the appearance aesthetic feeling is improved, the visual impact on consumers is high, and the consumption experience and requirements of the consumers are met.

Description

technical field [0001] The invention relates to the technical field of making mobile phone back plates, in particular to a method for preparing a heat-sensitive color-changing pattern mobile phone back plate. Background technique [0002] The elements of mobile phone products include appearance, hardware and software. In the case that existing mobile phone products have the same hardware conditions, because the first thing consumers see is the appearance of the mobile phone product, the appearance of the mobile phone product is very important for consumers to buy the product. Existing mobile phones minimize the use of buttons and make the screen as large as possible. Therefore, the first thing consumers see is the back panel of the mobile phone. Therefore, how to make a mobile phone back panel with a beautiful appearance is the primary task of every company. Large mobile phone companies are constantly developing new processes, hoping to reduce production costs by adopting n...

AI Technical Summary

Problems solved by technology

The appearance of the existing mobile phone back panel is mostly a bright surface effect of a single color, and the pattern does not have the appearance effect of gradual color change, and will not change the appearance display of different colors with the change of temperature, and the appearance changeability is low , It is easy to cause consumers' aesthetic fatigue. With the diversification of consumers' pursuit of mobile phone back panel effects, the current single appearance effect of mobile phone back panels can no longer meet the needs of consumers.
