천연석무늬를 나타내는 사출성형 폴리올레핀 수지용 마스터 배치 조성물 및 이 마스터 배치조성물을 이용하는 폴리올레핀 수지 성형품 제조방법Master batch composition for injection molding polyolefin resin showing natural stone pattern and polyolefin resin molded article production method using the master batch composition
[발명의 상세한 설명]Detailed description of the invention
본 발명은 대리석, 화강암 등과 같은 천연석무늬의 외관을 나타나게 하는 폴리올레핀 수지 성형품 제조에 적용할 수 있는 마스터 배치(master batch)와 이 마스터 배치조성물을 이용하는 폴리올레핀 수지 성형품의 제조방법에 관한 것이다. 좀 더 상세히 설명하면, 본 발명은 사출 성형 가공법에 의해 천연석무늬와 유사한 외관을 보유하는 성형품 제작이 가능하며, 여러 종류의 폴리올레핀 수지에 적용할 수 있는 마스터 배치 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a master batch applicable to the production of a polyolefin resin molded article exhibiting the appearance of natural stone patterns such as marble and granite, and a method for producing a polyolefin resin molded article using the master batch composition. In more detail, the present invention is capable of producing a molded article having an appearance similar to a natural stone pattern by an injection molding process, and relates to a master batch composition applicable to various types of polyolefin resins.
현대 사회가 고도화되고 문명화됨에 따라 사람들은 자연스런 외관을 지닌 제품에 대한 선호도가 점차 증대되고 있다. 이와 같은 욕구를 만족시키는 하나의 방법으로 제품의 외관에 무늬를 부여하는 것이다. 그러나, 소비자의 요구는 일반 무늬의 외관에 거치지 않고 좀더 자연스러운 외관을 지닌 제품의 출현을 기대하고 있다. 좀 더 상세히 설명하면, 대리석무늬 또는 화강암무늬를 지닌 제품을 요구하고 있다.As modern society is advanced and civilized, people's preference for products with natural appearance is gradually increasing. One way to satisfy this desire is to give a pattern to the exterior of the product. However, the demands of consumers are expected not to go through the appearance of the general pattern, but the appearance of products with a more natural appearance. In more detail, they require products with marble or granite patterns.
상기한 바와 같은 욕구를 충족시키기 위하여 사출 성형품 외관에 무늬를 부여하는 종래의 방법은 사출 성형후 무늬를 형성시키는 방법이다. 그러나, 이와 같은 후공정에 의한 대리석무늬 또는 화강암무늬의 부여 방법은 추가 설비가 필요하고 생산성이 떨어지며 형태가 복잡한 성형품에는 적용하기 어려운 단점이 있다.The conventional method of imparting a pattern to the appearance of the injection molded article in order to satisfy the above needs is a method of forming a pattern after injection molding. However, the method of imparting a marble pattern or a granite pattern by such a post process has a disadvantage in that it is difficult to apply it to a molded article that requires additional equipment, reduces productivity, and has a complicated shape.
본 발명자는 종래의 무늬형성 방법의 문제점과 현재 발명되어 있는 여러가지 기술을 종합적으로 검토, 연구한 결과 사출 성형 과정에서 성형품 외관에 직접 천연석무늬가 나타날 수 있는 마스터 배치 조성물을 발명하게 되었다.The present inventors have comprehensively studied and studied the problems of the conventional pattern forming method and various technologies currently invented, and as a result, invented a master batch composition in which natural stone patterns appeared directly on the appearance of molded products during the injection molding process.
본 발명의 목적은 사출 성형품 외관에 무늬를 부여하는 종래의 방법이 가지고 있는 단점을 해결하고 사출 성형 과정에서 성형품 외관에 천연석 무늬가 직접 나타날 수 있는 마스터 배치 조성물을 제공하고저 하는 것이다.An object of the present invention is to solve the disadvantages of the conventional method for imparting the appearance of the injection molded article and to provide a master batch composition in which the natural stone pattern can appear directly on the appearance of the molded article during the injection molding process.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명의 주요 구성 성분은 폴리올레핀 수지, 폴리아미드 수지, 결합제, 안료, 가공조제, 분산제 등으로서 30~80중량부의 폴리올레핀 수지, 20~70중량부의 폴리아마이드 수지, 0.1~15중량부의 결합제, 1~10중량부의 안료, 5~15중량부의 가공조제, 0.1~10중량부의 분산제로 구성되어 있다.The main constituents of the present invention are polyolefin resins, polyamide resins, binders, pigments, processing aids, dispersants, etc., 30 to 80 parts by weight of polyolefin resin, 20 to 70 parts by weight of polyamide resin, 0.1 to 15 parts by weight of binder, 1 to 1 It consists of 10 weight part pigments, 5-15 weight part processing aids, and 0.1-10 weight part dispersing agent.
본 발명에 있어서, 상기의 천연석무늬가 발현되는 마스터 배치 조성물을 제조할 시, 용융점이 200℃ 이상인 폴리아마이드 수지를 사용하는 것과 성형가공시 사출 성형 온도를 220℃ 미만으로 설정하는 것이 중요하다. 즉, 본 발명에 제시된 마스터 배치를 폴리올레핀 수지에 첨가하여 사출성형하면, 부분적으로 미용융된 폴리아마이드가 성형품에 랜덤(Random)하게 분포되어 성형품 외관에 천연석무늬를 나타내게 된다.In the present invention, when preparing the master batch composition in which the natural stone pattern is expressed, it is important to use a polyamide resin having a melting point of 200 ° C. or more and to set the injection molding temperature to be less than 220 ° C. during the molding process. That is, when the master batch presented in the present invention is added to the polyolefin resin and injection molded, the partially unmelted polyamide is randomly distributed in the molded article to exhibit natural stone pattern on the appearance of the molded article.
본 발명에 유용한 베이스수지는 올레판을 주성분으로 하는 폴리올레핀계 수지, 예를들면 저밀도 폴리에틸렌, 중밀도 폴리에틸렌, 고밀도 폴리에틸렌, 폴리프로필렌, 에틸렌 또는 프로필렌과 다른 공중합 가능한 단량체와의 공중합체이다.Base resins useful in the present invention are copolymers of olefins based polyolefin resins such as low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene, ethylene or propylene with other copolymerizable monomers.
본 발명품에 사용되는 결합제는 무수 말레인산(maleic anhydride) 또는 그리시딜메타아크릴레이트(Glycidy methacrylate) 또는 하이드록시에틸 메타아크릴레이트가 공중합된 변성 폴리올레핀으로서, 폴리올레핀 수지와 폴리아마이드 수지와의 상용성을 향상시키는 것이 사용 목적이다.The binder used in the present invention is a modified polyolefin copolymerized with maleic anhydride or glycidyl methacrylate or hydroxyethyl methacrylate, which improves the compatibility between polyolefin resin and polyamide resin. It is the purpose of use.
그리고, 가공조제와 분산제는 통상의 폴리올레핀 수지용 마스터 배치 제조시 사용되는 종류의 범주에서 활용하면 된다. 본 발명은 상기의 조성 이외에 산화방지제, 열안정제, 자외선 안정제, 윤활제 등을 소량 첨가시킬 수 있다.In addition, the processing aid and the dispersant may be utilized in the category of the kind used in manufacturing a master batch for ordinary polyolefin resin. In the present invention, a small amount of an antioxidant, a heat stabilizer, an ultraviolet stabilizer, a lubricant, and the like can be added in addition to the above composition.
이러한 마스터 배치 조성물을 얻기 위하여 사용 가능한 혼련기로는 밤버리믹서, 단축혼련기, 2축혼련기코-니더 등이 있다. 혼련 중에 안료의 충분한 분산의 이루어지도록 하는 조건을 설정하는 것도 중요하다.Examples of kneaders that can be used to obtain such a master batch composition include bamboly mixers, uniaxial kneaders, biaxial kneaders and kneaders. It is also important to set the conditions such that sufficient dispersion of the pigment is achieved during kneading.
본 발명에 적용할 수 있는 융점 200℃ 이상의 폴리아미드수지로서는 나이론 6, 나이론 66, 나이론 610 등 융점이 200℃ 이상의 모든 폴리아미드 수지를 수용할 수 있다.As the polyamide resin having a melting point of 200 ° C. or higher applicable to the present invention, all polyamide resins having a melting point of 200 ° C. or higher, such as nylon 6, nylon 66, and nylon 610, can be accommodated.
본 발명의 마스터 배치 조성물을 폴리올레핀 수지에 약 2~3중량부를 첨가한 후 사출 성형하면 사출 성형 제품 표면에 천연석무늬가 나타나는 효과를 얻을 수 있다.When injection molding is performed after adding about 2-3 parts by weight of the master batch composition of the present invention to the polyolefin resin, the effect that natural stone patterns appear on the surface of the injection molded product can be obtained.
이하 본 발명을 실시예 및 비교예를 통하여 상세히 설명하면 다음과 같다. 그러나, 본 발명은 이들 실시예에 의하여 제한되지 않는다.Hereinafter, the present invention will be described in detail through Examples and Comparative Examples. However, the present invention is not limited by these examples.
