In addition, the temperature-sensitive pigment may include a pigment of iodide, such as mercury iodide salt. Such a temperature-sensitive pigment has a change in crystallinity according to the external temperature, the color changes accordingly, and when the temperature is restored to the initial temperature, the crystallinity is also restored, thereby returning the color to the original color to form a reversible temperature sensitive layer. do. The temperature-sensitive organic pigment as described above is mixed with the resin in a mixed organic solvent.
상기 온도감응형 안료로는 40∼50℃ 부근에서 변색한 후 다시 냉각하면 원색으로 돌아오는 특성을 갖는 것이 바람직하다.It is preferable that the temperature-sensitive pigment has a characteristic of returning to the primary color when discolored at around 40 to 50 ° C. and then cooled again.
또한, 상기 첨가제로는 아크릴 계열을 사용한다.In addition, an acrylic series is used as the additive.

다음에, 주성분인 우레탄 아크릴레이트계 수지 15 ∼ 20wt%에, 알코올류, 케톤류, 에스테르류중 선택된 적어도 하나의 용제 55 ∼ 60wt%, 온도변화에 감응하여 색상이 변화하는 안료 10 ∼ 15wt% 및 아크릴 첨가제 5 ∼ 10wt%가 혼합된 온도감응 도료 조성물을 상기 외관 케이스 수지사출물에 스프레이 방식으로 분사하여 도막층을 형성한다.Next, the urethane acrylate-based resin 15 to 20 wt% of the main component, 55 to 60 wt% of at least one solvent selected from alcohols, ketones and esters, pigments 10 to 15 wt% and the acrylic color changes in response to temperature changes Spraying the temperature-sensitive coating composition mixed with the additive 5-10wt% to the outer case resin injection by spraying to form a coating layer.
마지막으로, 상기 도료 도막층의 박리 및 변색을 방지하기 위하여 도료 도막층에 UV 투명 코팅을 실시한다. 즉, 자외선으로 광경화시킴으로써 내마모성이 우수한 단단한 피막을 입힌 후, 외관케이스의 도막작업을 완료한다.Finally, in order to prevent peeling and discoloration of the coating film layer, UV coating is applied to the coating film layer. In other words, after the photocuring with ultraviolet light to give a hard film excellent in wear resistance, the coating operation of the outer case is completed.
상기와 같이 온도변화에 감응하는 도료가 단말기의 외관케이스에 코팅되었을 경우, 예를들어 완제품이 RED, GREEN, YELLOW등의 색깔을 가질 경우, 외부온도나 손으로 단말기를 잡았을 경우에 감지되는 온도의 정도에 따라 외관케이스가 화이트 계열로 변색되어, 이색적인 느낌을 주게 된다. When the paint responding to temperature change is coated on the exterior case of the terminal as described above, for example, when the finished product has a color of RED, GREEN, YELLOW, etc., the temperature detected when the terminal is held by an external temperature or a hand Depending on the degree, the exterior case is discolored to white, giving a different feeling.
그리고, 일정시간이 경과하여 온도가 초기조건으로 회복되었을 경우, 외관케이스의 색갈도 원상복구된다. When the temperature is restored to the initial condition after a certain time, the color of the exterior case is restored.
이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능하다는 것이 본 발명이 속하는 분야에서 통상의 지식을 가진 자에게 있어서 명백할 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and it is common in the field of the present invention that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
전술한 바와 같이 본 발명에 따르면, 온도변화에 따라 색채가 변하도록 하는 도료를 단말기의 외관 케이스에 코팅하고, 박리되지 않도록 UV코팅을 실시함으로써, 사용자의 신체온도에 따라 단말기 외관 케이스의 색깔을 자유롭게 변화시켜 단말기의 외관을 미려하게 할 수 있으며, 고객의 까다로운 취향을 반영하고, 타 제품과의 차별성을 갖을 수 있는 효과가 있다. As described above, according to the present invention, by coating a coating material to change the color according to the temperature change on the exterior case of the terminal, and UV coating so as not to peel off, the color of the terminal exterior case freely according to the user's body temperature By changing the appearance of the terminal can be beautiful, it reflects the demanding taste of the customer, and has the effect of having a differentiation from other products.
