Description

성형성이 개량된 폴리에스테르 수지 조성물Polyester resin composition with improved moldability

[발명의 분야][Field of Invention]

본 발명은 유기계 핵제 및 무기계 핵제를 동시에 사용함으로써 성형성이 개량된 폴리에스테르 수지 조성물에 관한 것이다. 보다 구체적으로 본 발명은 유기계 핵제를 사용함으로써 결정화를 향상시켜 내열성 및 굴곡강도가 향상되고, 무기계 핵제를 사용함으로써 핵형성이 촉진되는 것을 특징으로 하는 성형성이 개량된 폴리에스테르 수지 조성물에 관한 것이다.The present invention relates to a polyester resin composition in which moldability is improved by simultaneously using an organic nucleating agent and an inorganic nucleating agent. More specifically, the present invention relates to a polyester resin composition having improved moldability, wherein crystallization is improved by using an organic nucleating agent to improve heat resistance and flexural strength, and nucleation is promoted by using an inorganic nucleating agent.

[발명의 배경][Background of invention]

자동차, 전기부품 및 전자부품의 성형재료로 널리 사용되고 있는 폴리에스테르 수지 조성물 중에서 폴리부틸렌 테레프탈레이트(PBT) 수지는 내열성이 우수하고 내약품성 및 기계적 강도가 우수하며 전기적 특성이 뛰어나 공업용 재료에 널리 쓰인다. 또한 유동성 및 사출성형성이 다른 엔지니어링 플라스틱에 비하여 매우 우수하다. 따라서 작고 얇은 부품을 사출할 경우 PBT는 우수한 성형성을 갖는다. 그러나 비강화된 PBT는 유리섬유로 강화된 PBT에 비하여 사출 싸이클 시간(cycle time)이 길기 때문에 생산성이 떨어진다. 이는 비강화 PBT의 결정화 시간이 유리섬유 강화 PBT 보다 길기 때문이며 이로 인해 싸이클 시간이 길어진다. 또한 동일 생산성을 유지할 수 있느 싸이클 시간에서는 부품이 금형에 박혀서 이형 불량이 발생된다.Polybutylene terephthalate (PBT) resin is widely used in industrial materials because of its excellent heat resistance, chemical resistance and mechanical strength, and excellent electrical properties among polyester resin compositions widely used as molding materials for automobiles, electrical parts and electronic parts. . In addition, flowability and injection molding are very good compared to other engineering plastics. Therefore, PBT has excellent formability when injecting small and thin parts. However, unreinforced PBT is less productive because the injection cycle time is longer than that of glass fiber reinforced PBT. This is because the crystallization time of the unreinforced PBT is longer than that of the glass fiber reinforced PBT, which results in a longer cycle time. In addition, during cycle time to maintain the same productivity, the mold is embedded in the mold and mold release failure occurs.

난연성 PBT 수지를 제조하기 위해서는 유기할로겐 화합물과 삼산화 안티몬을 혼합사용하는 방법이 가장 일반적으로 사용되고 있으며 이러한 방법들은 미국특허 제3,624,024호 및 영국특허 제1,285,829호에 개시되어 있다. 상기의 특허들에서는 유기 할로겐 화합물로 브롬함량이 높은 데카브로모디페닐옥사이드(decabromo diphenyl oxide)를 사용하였는데 이는 소량의 첨가로 난연성이 우수한 장점이 있지만 성형가공후 표면에 블루밍(blooming)되어 제품을 오염시키고 제품의 질을 떨어뜨리며 인체에 해로운 영향을 주기도 한다.In order to prepare a flame retardant PBT resin, a method using a mixture of an organohalogen compound and antimony trioxide is most commonly used, and these methods are disclosed in US Pat. No. 3,624,024 and UK Pat. No. 1,285,829. In the above patents, decabromo diphenyl oxide having a high bromine content is used as an organic halogen compound, which has an advantage of excellent flame retardancy by adding a small amount, but is contaminated with a product after being blown to the surface after molding. It may cause deterioration of the product and harmful effects on the human body.

이러한 문제를 해결하기 위해 대한민국 특허 공고 제81-1565호에서는 데카브로모 디페닐 옥사이드 대신에 브롬화 페놀에서 브롬을 치환시켜 얻은 축합생성물을 사용하는 기술이 제안되었다. 또한 일본 공개특허 공보 소49-1652호에서는 브롬화 비스페놀A와 포스겐으로부터 합성된 폴리카보네이트 올리고머를 사용하는 방법도 개시되어 있다. 또한 대한민국 특허공고 제93-1993호에서는 적인과 멜라민계 화합물을 이용하여 난연성에는 문제가 없지만 결정화 거동이 유리섬유 강화 PBT 수지에 비하여 떨어지므로 작고 얇은 부품들을 사출 성형할 때 이형불량을 근본적으로 제거하기는 어렵다.In order to solve this problem, Korean Patent Publication No. 81-1565 proposes a technique of using a condensation product obtained by substituting bromine in brominated phenol instead of decabromo diphenyl oxide. JP-A-49-1652 also discloses a method of using a polycarbonate oligomer synthesized from brominated bisphenol A and phosgene. In addition, in Korean Patent Publication No. 93-1993, there is no problem in flame retardancy by using red and melamine-based compounds, but the crystallization behavior is lower than that of glass fiber reinforced PBT resin, thereby fundamentally eliminating mold release defects when injection molding small and thin parts. Is difficult.

이에 본 발명자들은 유리섬유 강화 PBT 수지 정도의 싸이클 시간을 가지며 이형불량이 적고, PBT 수지가 가지고 있는 두 종류의 핵제를 동시에 사용함으로써 결정화 거동을 빠르게 하여 이형성 및 생산성이 향상된 폴리에스테르 수지 조성물을 개발하기에 이르렀다.Accordingly, the present inventors have a cycle time of about glass fiber reinforced PBT resin, have a low mold release defect, and use the two kinds of nucleating agents of PBT resin at the same time to speed up crystallization behavior to develop a polyester resin composition having improved releasability and productivity. Reached.

[발명의 목적][Purpose of invention]

본 발명의 목적은 유기계 핵제 및 무기계 핵제를 동시에 사용하여 용융결정화 온도를 상승시켜 결정화가 빨라진 폴리에스테르 수지 조성물을 제공하기 위한 것이다.An object of the present invention is to provide a polyester resin composition having a faster crystallization by increasing the melt crystallization temperature by using an organic nucleating agent and an inorganic nucleating agent simultaneously.

본 발명의 다른 목적은 내열성, 충격강도, 인장강도 등의 물성이 향상되어 성형성이 개량된 폴리에스테르 수지 조성물을 제공하기 위한 것이다.Another object of the present invention is to provide a polyester resin composition having improved moldability by improving physical properties such as heat resistance, impact strength, and tensile strength.

본 발명의 상기 및 기타의 목적들은 하기 설명되는 본 발명에 의하여 모두 달성될 수 있다.The above and other objects of the present invention can be achieved by the present invention described below.
