Description

리얼우드 성형물의 제조방법{Manufacturing method for molded product with real-wood}Technical Field [0001] The present invention relates to a method for manufacturing a molded article,

본 발명은 리얼우드(Real-wood) 성형물의 제조방법에 관한 것으로, 더욱 상세하게는, 천연 나무의 질감이 표현되는 리얼우드를 포함하는 성형물을 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a real-wood molding, and more particularly, to a method for manufacturing a molding containing real wood in which the texture of the natural wood is expressed.

리얼우드는 천연 목재를 원하는 목적에 맞게 가공한 것을 의미한다. 리얼우드는, 인공 목재나, 인공수지의 표면에 천연목재를 얇게 켠 리얼우드 시트를 입힌 다른 제품과는 다르게, 천연 나무의 질감이 생생하게 표현된다는 특징이 있다.Realwood means that natural wood is processed to the desired purpose. Unlike other artificial woods and other artificial wood-coated real woods on the surface of artificial resin, the texture of natural wood is vividly expressed.

리얼우드 성형물은, 제품의 표면에 리얼우드를 배치시켜, 천연 나무의 느낌이 표현될 수 있게끔 제조된 성형물을 의미한다. 상기 리얼우드 성형물은, 제품의 고급화를 위해, 자동차 핸들이나 대시보드(Dashboard) 등에 사용되는 내장재, 가전제품의 외면을 이루는 외장재 등으로 자주 사용되곤 한다.A real wood molded product refers to a molded product produced by placing real wood on the surface of a product so that the natural wood feeling can be expressed. The above-mentioned real wood molded product is often used as an interior material used for an automobile handle, a dashboard, etc., or as an exterior material forming an outer surface of a home appliance for the purpose of upgrading a product.

상기한 바와 같은 리얼우드가 포함된 성형물을 제조하기 위한 방법과 관련된 기술로서, 대한민국 공개특허 제10-2016-0107439호에는 하이글로시 리얼우드 제품 및 이의 제조방법이 개시되어 있다.As a technique related to a method for producing a molded article containing real wood as described above, Korean Patent Laid-Open No. 10-2016-0107439 discloses a high-gloss real wood product and a manufacturing method thereof.

상기 제조방법은, 먼저 우드 소재를 프레스 내에 투입하여 소정 형상의 우드층을 성형한다. 다음으로, 상기 우드층을 인서트 금형 내에 투입한 후, 일면에 코팅층을 1차로 사출 성형한다. 마지막으로, 상기 우드층의 타면에 타 부품과 결합구조를 가지도록 기재층을 2차로 사출 성형한다.In this manufacturing method, a wood material is first introduced into a press to form a wood layer of a predetermined shape. Next, the wood layer is injected into the insert mold, and then the coating layer is first injection-molded on one surface. Finally, the base layer is injection-molded on the other surface of the wood layer so as to have other components and a bonding structure.

그런데, 상기 제조방법에 있어서, 사출되는 소재는 매우 높은 온도를 지닌다. 따라서 리얼우드의 사출되는 소재와 접촉되는 면이 녹아내리거나, 리얼우드가 변색될 수도 있는 문제점이 있다.However, in the above manufacturing method, the material to be injected has a very high temperature. Therefore, there is a problem that the surface which comes into contact with the material to be injected of the real wood is melted or the real wood is discolored.

또한, 상기 제조방법에 있어서, 사출되는 소재는 매우 높은 압력을 지닌다. 따라서 리얼우드가 강한 힘으로 눌리게 되어, 리얼우드를 기존에 설계한 치수로 설계할 수 없을 뿐만 아니라, 리얼우드의 표면이 벌어지는 등의 손상을 입게 된다.Further, in the above manufacturing method, the material to be injected has a very high pressure. As a result, the real wood is pressed with a strong force, so that it is not only impossible to design the real wood with a dimension designed in the past, but also damages the surface of the real wood.

사출에 의한 압력에 리얼우드가 금형 코어면에 압착될 경우, 리얼우드의 천연 목재의 질감이 현저하게 저하된다. 그에 따라, 리얼우드 성형물이 인조 목재와 유사한 느낌을 받게 되고, 천연 목재의 느낌을 살리고자 리얼우드를 사용한 이유가 무색하게 된다.When the real wood is squeezed on the mold core surface by the injection pressure, the texture of the natural wood of the real wood is remarkably lowered. As a result, the real wood moldings have a feeling similar to synthetic wood, and the reason for using the real wood to make the feeling of natural wood is blurred.

본 발명은 상기와 같은 문제점을 해결하기 위해 창출된 것으로서, 성형과정에서 리얼우드가 손상되는 것을 방지하여 천연 목재의 질감을 선명하게 드러낼 수 있는 리얼우드 성형물의 제조방법을 제공하는 데 목적이 있다.It is an object of the present invention to provide a method of manufacturing a real wood molding which is capable of clearly showing the texture of natural wood by preventing the real wood from being damaged during the molding process .

본 발명은, 리얼우드의 배면에 보강필름을 부착하는 단계; 상기 리얼우드의 전면을 브러싱하는 단계; 상기 리얼우드와 함께 플라스틱 수지를 인서트 사출하는 단계; 및 상기 리얼우드의 전면을 도장하는 단계를 포함하는 리얼우드 성형물의 제조방법을 제공한다.The present invention relates to a method of manufacturing a reinforced polyester film, comprising: attaching a reinforcing film to a rear surface of a real wood; Brushing the front surface of the real wood; Inserting a plastic resin together with the real wood; And painting the front surface of the real wood.

상기 인서트 사출단계는, 사출 금형의 내부에 완충재를 구비하여, 사출시 상기 리얼우드의 전면이 상기 완충재와 접하도록 할 수 있다. 여기서 상기 완충재는 실리콘, 고무 및 우레탄 중에서 선택된 어느 하나로 만들어질 수 있다.The insert injection step may include a buffer material inside the injection mold so that the front surface of the real wood contacts the buffer material at the time of injection. The cushioning material may be made of any one selected from silicone, rubber and urethane.

본 발명에 따른 리얼우드 성형물의 제조방법에 의하면, 성형과정 중에 리얼우드가 손상되는 것을 방지하여 천연 목재의 질감을 선명하게 드러낼 수 있다.According to the method of manufacturing a real wood molding according to the present invention, the real wood can be prevented from being damaged during the molding process, and the texture of the natural wood can be clearly displayed.

본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 다른 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 첨부된 청구범위의 기술적 사상에 의하여 정해져야 할 것이다.While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.

도 1은 본 발명의 실시예에 따른 리얼우드 성형물의 제조방법을 나타낸 흐름도, 도 2는 도 1에 나타낸 리얼우드의 전면이 브러싱되는 과정을 도시한 단면도, 도 3은 도 1에 나타낸 인서트 사출 과정을 도시한 단면도, 도 4는 도 1의 제조방법에 의해 제조된 리얼우드 성형물의 단면도이다. 이하 첨부 도면을 참조하여 본 발명의 실시예를 상세히 설명하도록 한다. 1 is a cross-sectional view illustrating a process of brushing a front surface of a real wood shown in FIG. 1, FIG. 3 is a cross-sectional view illustrating a process of inserting an insert according to an embodiment of the present invention, Fig. 4 is a sectional view of a real wood formed by the manufacturing method of Fig. 1; Fig. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 실시예에 따른 리얼우드 성형물(100)을 제조하기 위해, 먼저 리얼우드(110)의 배면에 보강필름(120)을 부착한다(S10).The reinforcing film 120 is attached to the rear surface of the real wood 110 (S10) to manufacture the real molded article 100 according to the embodiment of the present invention.

상기 보강필름(120)은, 사출되는 수지로부터 무늬목의 손상을 보호하는 동시에, 사출되는 수지와 부착이 가능한 플라스틱 소재를 적용한다.The reinforcing film 120 is made of a plastic material capable of adhering to the resin to be injected while protecting damage to the veneer from the resin to be injected.

다음으로, 상기 리얼우드(110)의 전면을 브러싱(Brushing)한다(S20). 천연 목재는 크고 작은 수많은 홈들(110a)이 표면에 형성되어 있다. 상기 홈(110a)은 나이테일 수도 있고, 외부의 영향에 의해 생겨진 것일 수도 있다.Next, the front surface of the real wood 110 is subjected to brushing (S20). The natural wood has numerous grooves 110a formed on its surface, large and small. The groove 110a may be formed by age or by external influences.

상기 홈(110a) 부위는 목재의 다른 부위보다 상대적으로 밀도가 낮다. 따라서 상기 리얼우드(110)의 표면을 브러시(110b)로 작업하는 경우, 도 2에 도시된 바와 같이 상기 홈(110a) 부위가 깊게 파이게 된다. 상기 S20 단계를 통해, 상기 리얼우드(110)가 가지는 천연 목재의 질감을 향상시킬 수 있다.The groove 110a portion is relatively denser than other portions of the wood. Accordingly, when the surface of the real wood 110 is worked with the brush 110b, the groove 110a is deeply fired as shown in FIG. Through the step S20, the texture of the natural wood of the real wood 110 can be improved.

그 다음으로, 상기 리얼우드(110)와 함께 플라스틱 수지(140)를 인서트 사출한다(S30). 더욱 상세하게는, 금형(10)상에 상기 리얼우드(110)와 보강필름(120)이 합지된 시트를 삽입한 뒤, 상기 보강필름(120) 상으로 상기 플라스틱 수지(140)를 사출하여 성형한다.Next, the plastic resin 140 is insert-injected together with the real wood 110 (S30). More specifically, after inserting a sheet in which the real wood 110 and the reinforcing film 120 are laminated on the mold 10, the plastic resin 140 is injected onto the reinforcing film 120, do.

이 때, 상기 인서트 사출단계(S30)에서, 사출 금형의 내부에 완충재(130)를 구비하여, 사출시 상기 리얼우드(110)의 전면이 상기 완충재(130)와 접하도록 할 수 있다. 여기서 상기 완충재(130)로는 실리콘, 고무 및 우레탄 중에서 선택된 어느 하나를 사용하는 것이 바람직하지만, 이에 한정되는 것은 아니다.At this time, in the insert injection step S30, the cushioning material 130 may be provided in the injection mold so that the front surface of the real wood 110 contacts the cushioning material 130 at the time of injection. As the buffer material 130, it is preferable to use any one selected from silicone, rubber, and urethane, but it is not limited thereto.

앞서 언급한 바와 같이, 사출되는 소재는 매우 높은 압력을 지닌다. 따라서 리얼우드가 강한 힘으로 눌리게 되어, 리얼우드 표면이 금형 코어면에 압착되어 리얼우드 특유의 표면질감이 저하될 뿐 아니라, 리얼우드의 표면이 손상을 입게 된다.As mentioned earlier, the material being injected has a very high pressure. As a result, the real wood is pressed with a strong force, and the surface of the real wood is pressed against the surface of the mold core, so that the surface texture of the real wood is deteriorated and the surface of the real wood is damaged.

하지만, 상기 완충재(130)가, 브러싱 처리된 상기 리얼우드(110)의 전면과 상기 금형(10) 사이에 삽입되는 경우, 사출되는 소재가 상기 리얼우드(110)에 가하는 압력을 상기 완충재(130)가 흡수한다. 이에 따라, 상기 리얼우드(110)에 가해지는 압력에 의한 리얼우드(110)의 손상을 줄일 수 있게 된다.However, when the cushioning material 130 is inserted between the front surface of the brushed real wood 110 and the mold 10, the pressure exerted by the material to be injected on the real wood 110 is lower than the pressure applied to the cushioning material 130 ). Accordingly, damage to the real wood 110 due to the pressure applied to the real wood 110 can be reduced.

마지막으로, 상기 리얼우드(110)의 전면을 도장한다(S40). 상기 도장층(150)은, 외부로부터 상기 리얼우드(110)의 표면이 손상되는 것을 방지하며, 상기 리얼우드(110)의 천연 목재 질감 및 광택을 오랫동안 유지할 수 있게 한다.Finally, the front surface of the real wood 110 is painted (S40). The coating layer 150 prevents the surface of the real wood 110 from being damaged from the outside and allows the natural wood texture and gloss of the real wood 110 to be maintained for a long time.

이상에서 살펴본 바와 같이, 본 발명에 따른 리얼우드 성형물(100)의 제조방법에 의하면, 성형과정 중에 리얼우드(110)가 손상되는 것을 방지하여 천연 목재의 질감을 선명하게 드러낼 수 있다.As described above, according to the manufacturing method of the real wood product 100 according to the present invention, the real wood 110 is prevented from being damaged during the molding process, and the texture of the natural wood can be clearly displayed.
