본 발명은 상기의 문제점을 해결하기 위해서 안출된 것으로서 본 발명의 고분자 수지 조성물의 혼합비율을 조절함으로써 혼합 시 발생하는 비상용성에 의한 기계적 물성 저하를 방지하여 기계적 물성이 우수한 수지 조성물을 제공하는 데 그 목적이 있다.Disclosure of the Invention The present invention has been devised to solve the above problems, and it is an object of the present invention to provide a resin composition having excellent mechanical properties by controlling the mixing ratio of the polymeric resin composition of the present invention, .

그리고, 본 발명의 또 다른 목적은 상기 수지 조성물을 용도에 따라 물리적 성질을 강화 또는 감소시켜 자동차, 선박, 건축, 일반산업에 다양하게 적용 가능하도록 하는 것이다.Another object of the present invention is to make the resin composition to be variously applied to automobiles, ships, buildings, and general industries by strengthening or reducing the physical properties depending on the use.

본 발명은 상술한 목적을 달성하기 위한 것으로, 본 발명에 따른 복합소재 스크랩의 재사용을 위한 복합소재 수지 조성물은 열가소성올레핀(Thermoplastic Olefin, TPO)계 수지 50~80중량%, 복합소재스크랩 10~50중량%, 상용화제 0.5~5중량%, 커플링제 0.1~0.5중량%를 포함하는 것을 특징으로 한다.The composite material resin composition for reuse of composite scrap according to the present invention comprises 50 to 80% by weight of a thermoplastic olefin (TPO) resin, 10 to 50 By weight, 0.5 to 5% by weight of a compatibilizer, and 0.1 to 0.5% by weight of a coupling agent.

상기 과제의 해결 수단에 의해, 본 발명의 복합소재 스크랩의 재사용을 위한 복합소재 수지 조성물은 복합소재의 스크랩을 재사용하여 일반 폴리올레핀 수지 대비 굴곡강도, 인장강도, 충격강도, 신율 등 기계적 물성이 향상된 TPO계 복합소재 수지 조성물을 제공할 수 있는 효과를 가진다.According to the solution of the above problems, the composite material resin composition for reusing the composite scrap of the present invention can be obtained by reusing scraps of the composite material to obtain a TPO having improved mechanical properties such as flexural strength, tensile strength, impact strength, elongation, Based composite resin composition according to the present invention.

본 발명의 복합소재 수지 조성물은 열가소성올레핀(Thermoplastic Olefin, TPO)계 수지 50~80중량%, 복합소재스크랩 10~50중량%, 상용화제 0.5~5중량%, 커플링제 0.1~0.5중량%를 포함하여 구성되는 것을 특징으로 한다.
The composite resin composition of the present invention comprises 50 to 80% by weight of a thermoplastic olefin (TPO) resin, 10 to 50% by weight of composite scrap, 0.5 to 5% by weight of a compatibilizer and 0.1 to 0.5% by weight of a coupling agent .

먼저, 본 발명인 복합소재 수지 조성물을 구성하는 열가소성올레핀(Thermoplastic Olefin, TPO)계 수지는 폴리프로필렌호모폴리머(PP Homo Polymer, PP-H)를 단독으로 사용하거나, 폴리프로필렌 복합체를 사용할 수 있다.First, the thermoplastic olefin (TPO) resin constituting the composite material resin composition of the present invention may be a polypropylene homopolymer (PP-H) alone or a polypropylene composite.

상기 폴리프로필렌 복합체는 폴리프로필렌호모폴리머(PP Homo Polymer, PP-H), 폴리프로필렌랜덤코폴리머(PP Random Copolymer,PP-R), 폴리프로필렌블럭코폴리머(PP Block Copolymer,PP-B), 알파올레핀계 엘라스토머를 포함하여 구성할 수 있다. The polypropylene composite may be a polypropylene homopolymer (PP-H), a polypropylene random copolymer (PP-R), a PP block copolymer (PP-B) Based elastomer and an olefin-based elastomer.

상기의 열가소성올레핀(Thermoplastic Olefin, TPO)을 폴리프로필렌 복합체로 사용할 경우 상기 폴리프로필렌 복합체는 폴리프로필렌호모폴리머(PP Homo Polymer, PP-H) 70~80중량%, 폴리프로필렌랜덤코폴리머(PP Random Copolymer,PP-R) 5~20중량%, 폴리프로필렌블럭코폴리머(PP Block Copolymer,PP-B) 5~20중량%, 알파올레핀계 엘라스토머 5~20중량%으로 구성되는 것을 사용하는 것이 바람직하다.When the above thermoplastic olefin (TPO) is used as a polypropylene composite, the polypropylene composite contains 70 to 80% by weight of a polypropylene homopolymer (PP-H), a polypropylene random copolymer (PP Random Copolymer 5 to 20% by weight of polypropylene block copolymer (PP-R), 5 to 20% by weight of PP block copolymer (PP-B) and 5 to 20% by weight of alpha-olefin elastomer.

한편, 상기의 열가소성올레핀(Thermoplastic Olefin, TPO)계 수지는 50~80중량%를 사용하는데, 50중량% 미만으로 사용할 경우 TPO계 수지 내의 PP의 특징인 경량성, 가공성 등의 장점을 충분히 발현하기 어렵고 90중량%를 초과할 경우 기계적 물성이 크게 저하되는 문제가 발생한다.
On the other hand, the thermoplastic olefin (TPO) -based resin is used in an amount of 50 to 80% by weight. When the amount of the thermoplastic olefin resin is less than 50% by weight, advantages such as lightness and workability, If the content is more than 90% by weight, the mechanical properties are greatly deteriorated.

그리고, 상기 복합소재스크랩은 폴리프로필렌(polypropylene, PP), 유리섬유(Glass fiber), 발포제를 포함하며, 폴리에틸렌테레프탈레이트(polyethylene terephthalate, PET) 부직포가 겹층되어진 것을 사용한다.The composite scrap includes polypropylene (PP), glass fiber, and a foaming agent, and a nonwoven fabric made of polyethylene terephthalate (PET) is laminated.

상기 복합소재스크랩은 폴리프로필렌(polypropylene, PP) 25~70중량%, 유리섬유(Fiber glass) 25~75중량%, 발포제 0~5중량%으로 구성되는 것을 사용하는 것이 바람직하다.The composite scrap is preferably composed of 25 to 70% by weight of polypropylene (PP), 25 to 75% by weight of glass fiber, and 0 to 5% by weight of a foaming agent.

한편, 상기 복합소재스크랩은 10~50중량%를 사용하는데, 10중량% 미만으로는 본 발명의 복합소재 수지 조성물의 기계적 강도가 충분히 발현되지 않아 기존의 TPO 수지 조성물과 차이가 없고 50중량%를 초과할 경우 과도한 스크랩 함량으로 인해 가공성에 문제가 생긴다.
On the other hand, the composite material scrap is used in an amount of 10 to 50% by weight. When the composite material scrap is less than 10% by weight, mechanical strength of the composite resin composition of the present invention is not sufficiently exhibited. Excessive scrap content causes problems in processability.

그리고, 상기 상용화제는 폴리프로필렌그라프트말레익산(PP-g-MAH)로, 용융흐름지수(MFI) 5~15g/10min, 녹는점(Melt Point) 160~182℃, 굴곡모듈러스 700~880MPa, 인장강도 15~22MPa, 신장율 5~12%인 것을 사용할 수 있다.The compatibilizer is polypropylene grafted maleic acid (PP-g-MAH) having a melt flow index (MFI) of 5 to 15 g / 10 min, a melting point of 160 to 182 ° C, a flexural modulus of 700 to 880 MPa, A tensile strength of 15 to 22 MPa, and an elongation percentage of 5 to 12%.

또한, 상기 상용화제는 밀도가 1.1~1.3g/cm³, 지름 6~8mm의 과립상(soft granules)인 것이 바람직하다.The compatibilizer is preferably soft granules having a density of 1.1 to 1.3 g / cm < 3 > and a diameter of 6 to 8 mm.

한편, 상기 상용화제는 0.5~5중량%를 사용하는데, 0.5중량% 미만으로 사용할 경우에는 상용성이 없어 혼합이 어려워지며 5중량%를 초과할 경우 과도한 사용으로 저분자량에 따른 영향이 물성의 저하를 일으키는 문제가 생긴다.
On the other hand, the compatibilizing agent is used in an amount of 0.5 to 5% by weight. When the amount of the compatibilizing agent is less than 0.5% by weight, mixing is difficult due to lack of compatibility. When the amount of the compatibilizing agent is more than 5% by weight, . ≪ / RTI >

그리고, 상기 커플링제는 실란계로 화학구조식은 R-Si-X 이며, R은 알킬기(Alkyl group)이고, X는 클로라이드(Cl), 메톡시기(Methoxy group) 중 어느 하나인 것을 사용한다.The coupling agent is a silane compound, and the chemical structural formula thereof is R-Si-X, R is an alkyl group (Alkyl group), and X is any one of chloride (Cl) and methoxy group.

상기 커플링제는 유리섬유(Glass fiber)와 반응하여 분산을 용이하게 해 결부시키기 어려운 유기재료와 무기재료를 연결하는 중개역할을 한다.The coupling agent acts as a mediator between the organic material and the inorganic material, which is difficult to be easily dispersed by reacting with the glass fiber.

고분자 수지 내에서 알킬기의 가수분해 반응, 올리고머 생성 축합반응, 생성 올리고머 기질(substrate) 표면의 -OH 기들과 수소결합 반응, 건조 혹은 경화 단계에서의 물의 손실과 동시에 기질과의 공유결합 형성 반응을 통하여 유기재료 내의 무기재료의 분산을 용이하게 한다.Hydrolysis of alkyl groups in the polymer resin, oligomer-condensation reaction, hydrogen bond reaction with -OH groups on the surface of the resulting oligomer, loss of water in the drying or curing stage, and simultaneous covalent bond formation with the substrate Thereby facilitating dispersion of the inorganic material in the organic material.

또한, 상기 커플링제는 0.1~0.5중량%를 사용하는데, 0.1중량% 미만으로 사용할 경우에는 계면 접착성을 충분히 높히지 못해 복합재료의 특성을 향상시키기 어렵고 0.5중량%를 초과할 경우 전체적인 물성 하락의 원인이 될 수 있다.If the amount of the coupling agent is less than 0.1% by weight, it is difficult to improve the properties of the composite material because the interfacial adhesion can not be sufficiently increased. When the amount of the coupling agent is more than 0.5% by weight, It can be a cause.

상기 중합 시 가공조제 및 기타 첨가제를 더 포함하여 중합할 수 있다.
The polymerization may further include a processing aid and other additives during the polymerization.

그리고, 본 발명의 복합소재 수지 조성물을 이용하여 복합소재를 제조할 경우 이축압출기(Twin extruder)를 이용하여 용융혼합법(melting compounding)으로 제조되며, 배합체를 선배합 한 후 특정 가공온도로 압출 가공하여 펠렛타이징(pelletizing)을 통해 펠렛 형상으로 제조된다.
When a composite material is manufactured using the composite resin composition of the present invention, the composite material is manufactured by melting compounding using a twin extruder.
