Description
본 발명은 폴리우레탄으로 제작하는 볼(ball)의 구성과 그 제조방법에 관한 것으로, 볼의 표면이 매끄러운 곡면이 되도록 하고 광택이 나도록 하여 상품성이 향상되도록 하는 것이다.The present invention relates to a configuration of a ball made of polyurethane (ball) and a method of manufacturing the same, so that the surface of the ball to be smooth curved and polished to improve the commerciality.
일반적인 볼은 가죽 표피나 인조가죽 표피 내부에 고무튜브가 내장되거나 단지 고무튜브만으로 형성되고, 상기 고무튜브에 탄력적으로 신축되어 공기를 주입할 수 있는 공기주입부가 형성되어, 공기주입부를 통해 공기를 주입시키면 고무튜브가 공기압력에 의해 부풀도록 되어 있다.The general ball is a rubber tube inside the leather skin or artificial leather skin or is formed of only a rubber tube, and the rubber tube is elastically stretched to form an air injection unit for injecting air, injecting air through the air injection unit The rubber tube is then inflated by air pressure.
이러한 볼은 내부의 공기압력에 의해 팽창된 고무튜브의 탄력에 의해 구의 형태를 유지하고 표면에 외력이 작용되면 그 탄발력에 의해 튀어 오르며, 이러한 원리를 이용하여 각종 운동이나 놀이를 하도록 한다.The ball maintains the shape of the sphere by the elasticity of the rubber tube inflated by the air pressure inside, and when the external force is applied to the surface, the ball bounces due to its elastic force.
그러나 이러한 볼은 시간이 경과되면서 공기주입구를 통해 미세하게 공기가 누출되거나 고무튜브의 변질로 인해 장시간이 지나면 내부 압력이 저하되고, 이로 인해 탄발력이 저하되어 볼의 기능이 상실되게 되는 단점이 있었다.However, such a ball has a disadvantage in that the internal pressure is reduced after a long time due to the air leakage through the air inlet or deterioration of the rubber tube over time, due to the elasticity is lowered due to the loss of ball function .
한편, 이러한 고무튜브 볼의 단점을 보완하는 것으로 폴리우레탄을 발포시켜 포움(foam)으로 제작하는 볼이 있으며, 이러한 종래 우레탄 볼은 별도의 고무튜브가 없이 발포된 우레탄이 구형상의 포움으로 성형되고, 성형된 볼의 표면에 코팅(coating)에 의한 피막이 형성되는 구조로 되어 있다.On the other hand, to compensate for the disadvantages of the rubber tube ball, there is a ball made of foam (foam) by foaming polyurethane, such a conventional urethane ball is a polyurethane foam is formed into a spherical foam without a separate rubber tube, The coating is formed on the surface of the formed ball by coating.
이러한 종래 우레탄 볼은 폴리우레탄 원료들을 희석하면 기포가 발생되는데, 이러한 원리를 이용하여 포움(foam)과 같이 발포시켜 제조하는 것으로, 소정 직경을 갖는 구형상의 금형 내부에 액상의 폴리우레탄 원료들을 주입시켜 금형 내부에서 일정 직경과 소정의 탄력을 갖는 구형상의 포움성형물을 제조하고, 상기 포움성형물의 표면에 코팅액을 스프레이 방식으로 분사시켜 코팅 처리하였다.This conventional urethane ball is produced by diluting the polyurethane raw materials, bubbles are produced by using the principle, such as foam (foam) by manufacturing, by injecting a liquid polyurethane raw material into a spherical mold having a predetermined diameter A spherical foam molding having a predetermined diameter and predetermined elasticity was prepared in the mold, and the coating solution was sprayed onto the surface of the foam molding by spraying to coat the coating.
이러한 종래 우레탄 볼은 내부가 소정의 탄성을 갖는 발포형태의 포움으로형성되어 시간이 경과되어도 탄력의 변화가 없으며, 외력이 작용되면 일반 고무튜브 볼과 같은 탄발력을 갖고 튀어 오르게 된다.Such a urethane ball is formed as a foam having a predetermined elasticity inside, there is no change in elasticity over time, and when an external force is applied, the urethane ball bounces with elasticity similar to that of a general rubber tube ball.
그러나, 이러한 종래 우레탄 볼은 금형 내부에서 발포된 성형물의 표면에 스프레이 코팅에 의한 표면처리를 하기 때문에, 성형물의 표면에 금형 연결부위와 기포에 의한 음양곽이 그대로 남아 있고, 이로 인해 코팅처리를 할지라도 표면이 매끄럽지 못하고 광택이 나지 않아 상품성이 저하되는 단점이 있었다.However, since the conventional urethane ball is surface-treated by spray coating on the surface of the molded product foamed in the mold, the mold connection portion and the yin and yang by the bubbles remain on the surface of the molded product, and even if the coating process The surface was not smooth and not shiny, and there was a disadvantage in that the merchandise was deteriorated.
본 발명은 폴리우레탄 원료를 발포시켜 성형하는 포움성형물의 표면에 가소성 고무주머니인 플렉시블튜브(flexible tube)를 씌우고, 상기 플렉시블튜브의 표면이 액상의 우레탄 코팅액에 의해 코팅 처리한 후 건조시켜, 볼의 표면 전체가 매끄러운 곡면이 되도록 하고 광택이 나도록 하므로, 그 상품성이 향상되도록 하는데 그 목적이 있다.According to the present invention, a flexible tube, which is a plastic rubber bag, is placed on a surface of a foam molding formed by foaming a polyurethane raw material, and the surface of the flexible tube is coated with a liquid urethane coating solution and then dried. Since the entire surface is smooth and polished, the purpose is to improve the marketability.
