Abstract

The present invention relates to a method of forming bonding materials having curved surfaces. When a sheet expressing a natural surface texture and a glass fiber composite material as a reinforcement of the sheet are bonded, the method includes heating the glass fiber reinforcement instantly at a high temperature before carrying out a press, and carrying out a press while cooling a lower mold, thereby preventing the surface expression sheet and the glass fiber reinforcement from being deformed or changing in color due to heat. In addition, a crack generated where a curved surface is formed may be prevented. Thus, a failure rate in production of products is reduced and product quality is improved.

Description

곡면을 갖는 접합소재의 성형방법{Forming method of bonding materials having a curved surface}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forming method of a bonded material having a curved surface,

본 발명은 곡면을 갖는 접합소재의 성형방법에 관한 것으로, 더욱 상세하게는 나무, 천, 종이, 도자기와 같이 천연의 표면 질감을 표현하고, 취성이 강한 소재로 이루어진 시트와 유리섬유보강재를 서로 접합하면서, 일부분은 삼차원적 곡면으로 포밍되도록 하는 곡면을 갖는 접합소재의 성형방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of molding a bonded material having a curved surface, and more particularly, to a method of molding a bonded material having a curved surface, And a curved surface that is partly formed into a three-dimensional curved surface.

일반적으로 수지 재질은 가볍고 또한 가공성이 좋아서 다양한 물품의 케이스 또는 하우징을 만드는 용도로 사용되고 있음은 주지된 사실이다.It is well known that the resin material is generally used for making a case or a housing of various articles because it is light and has good processability.

그러나 수지 재질로 제조된 제품은 가볍고 질긴 특성으로 실용적으로 사용할 수 있는 큰 장점이 있는데도 불구하고, 단지 인공적이며 딱딱한 분위기의 질감을 준다는 재질 자체가 단점으로 인하여 소비자들로 하여금 저가의 제품이라고 하는 인식을 갖게 하고 있음이 현 실정이다.However, in spite of the fact that the product made of the resin material has a great advantage that it can be practically used because of its light and tough characteristics, it has the disadvantage of the material itself which gives only the artificial and hard texture of the atmosphere, This is the current situation.

주지하는 바와 같이 소비자의 선호도를 높이기 위해 사출성형 제품을 비롯하여 다양한 형태의 디자인으로 제공되고 있다.As well known, various types of designs are being offered, including injection molding products, to enhance consumer preference.

그런데 대부분의 사출성형 제품은 제품의 형상과 모양에 비중을 두고 디자인을 개발하고 있고, 이러한 경우에 디자인 개발에 한계가 있기 때문에 사출성형 제품을 제조한 후에 다양한 무늬를 스크린 인쇄하거나, 전사지를 이용해서 무늬를 전사하고 있다.However, since most of the injection molding products are designed based on the shape and shape of the product, there are limitations in the design development in such cases. Therefore, after the injection molding product is manufactured, various patterns can be screen printed, The pattern is transferred.

그러나 스크린 인쇄나 전사지를 이용하여 하우징에 무늬를 형성할 경우, 그 형태가 조잡하고, 특히 시간이 흐름에 따라 광택이나 색상이 닳기 때문에 새로이 다시 데코레이션을 해야 하는 등 수명에 한계가 있는 단점이 있다.However, when a pattern is formed on a housing using a screen printing or a transfer paper, its shape is coarse, and there is a limitation in life such as a new decoration is required because gloss or color wears over time.

따라서 소비자의 안목에 부합하기 위해 독특한(천연물의 질감) 소재를 구현하면서도 하우징의 강성과 미려함을 동시에 제고할 수 있는 하우징의 개발이 필요하다.Therefore, it is necessary to develop a housing which can enhance the rigidity and the beauty of the housing at the same time while realizing a unique (natural material) material in order to meet the consumers' eyes.

이러한 이유로 종래에는 특수도료를 도포하여 천연물의 질감을 표현하거나, 또는 공개특허 제10-2010-0025050호(2010.03.09)에서와 같이 천연물의 질감을 갖는 시트를 수지로 이루어진 하우징에 접합하여, 하우징에 그 질감을 표현하였다.For this reason, conventionally, a special paint is applied to express the texture of a natural product, or a sheet having a texture of a natural material is bonded to a housing made of a resin as disclosed in Patent Publication 10-2010-0025050 (Mar. 3, 2010) To express its texture.

하지만 천연물의 질감을 표현하는 시트들은 그 취성이 비교적 강해 외관 성형(포밍)시 크랙 등이 발생하여, 제품이 품질이 저하될 뿐만 아니라, 불량률이 높은 문제점을 가지고 있었다.
However, the sheets expressing the texture of the natural material have relatively strong brittleness, which causes cracks and the like in appearance molding (forming), resulting in not only a deterioration in the quality of the product but also a high defect rate.

본 발명은 천연의 표면 질감을 표현하는 시트와 그 시트의 보강재로 유리섬유복합소재를 접합하는데, 압착(프레스)을 실시하기 전, 유리섬유보강재 만을 고온으로 순간 예열하고, 압착(프레스)을 실시할 시, 하부금형을 냉각하면서 압착(프레스)을 실시해, 상기 표면표현시트 및 유리섬유보강재가 열에 의한 변형 또는 변색되는 것을 방지하고, 곡면 성형부분에서 발생하는 크랙이 방지되는 곡면을 갖는 접합소재의 성형방법을 제공하는 것을 그 목적으로 한다.
The present invention relates to a method of joining a glass fiber composite material with a sheet expressing a natural surface texture and a reinforcing material of the sheet, wherein only the glass fiber reinforcing material is preheated to a high temperature instantaneously before the compression (press) (Pressing) while cooling the lower mold to prevent the surface expression sheet and the glass fiber reinforcing material from being deformed or discolored due to heat and to prevent the cracks generated in the curved surface forming portion And to provide a molding method.
