More specifically, the synthetic resin products used as batteries and peripheral parts in battery-based electric vehicles meet the flame retardant UL94 V0 rating. Engineering plastic for electric vehicles that has improved flame retardant properties and can be implemented in multi-color to prevent harm to the human body while securing it, and further to enable multi-color implementation, including orange color, to facilitate product classification and ensure diversity. It relates to a method of manufacturing the composition.
현재 자동차산업은 내연기관 자동차에서 유류를 소비하지 않는 전기자동차 등의 친환경 미래형자동차로의 개발이 가속화되고 있다. Currently, the automobile industry is accelerating the development of eco-friendly future vehicles, such as electric vehicles that do not consume oil, from internal combustion engine vehicles.
이러한 급격한 변화에 대응하여 배터리를 기본으로 하는 전기자동차는 배터리 및 주변 부품에 장착되는 플라스틱 부품(재료)에 난연등급을 UL94 V0 등급으로 유지할 것으로 요구하고 있으며, 더불어 배터리 부품(전자부품)을 표현하기 위해 오렌지 칼라를 포함한 멀티칼라가 구현될 수 있도록 플라스틱 재료를 요구하고 있다.In response to these rapid changes, battery-based electric vehicles are required to maintain a flame retardancy rating of UL94 V0 for plastic parts (materials) mounted on the battery and surrounding parts, and in addition, it is required to express battery parts (electronic parts) For this reason, plastic materials are being requested so that multi-colors including orange color can be realized.
이때, 전기자동차의 배터리 관련 플라스틱 부품으로는 카트리지(Cartridge), MSD(Manual Service Disconnect) 메일 하우징(Male Housing), ASM-BDU(Battery Disconnect unit) 메인 프레임, ASM-BDU 메인 컨텍터(Contactor), MSD 피메일 로우(Female Lower) 등 다양하다.At this time, plastic parts related to the battery of electric vehicles include cartridge, MSD (Manual Service Disconnect) Male Housing, ASM-BDU (Battery Disconnect unit) main frame, ASM-BDU main contactor, There are various types such as MSD Female Lower.
하지만, 높은 난연성을 확보하기 위해 주로 사용되고 있는 난연제는 할로겐계 난연제로 유독가스 배출(맹독성), 환경오염(다이옥신 배출) 등의 문제로 사용이 규제되고 있다.However, the flame retardants that are mainly used to ensure high flame retardancy are halogen-based flame retardants, and their use is regulated due to problems such as toxic gas emissions (highly toxic) and environmental pollution (dioxin emissions).
이에, 비할로겐계 난연제인 인계난연제가 활용되고 있는데, 인계난연제는 다양한 칼라를 구현하는데 많은 어려움이 있고, 나아가 기계적물성을 저하시키므로 이에 대한 개선이 필요한 시점이다.Accordingly, phosphorus-based flame retardants, which are non-halogen-based flame retardants, are being used, but phosphorus-based flame retardants have many difficulties in realizing various colors and further deteriorate mechanical properties, so improvement is needed.
본 발명은 상술한 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 배터리를 기본으로 하는 전기자동차에서 배터리 및 주변 부품으로 사용되는 합성수지 제품이 난연 UL94 V0 등급을 확보하면서 인체 유해성은 차단할 수 있고, 나아가 오렌지 칼라를 포함하는 멀티칼라 구현이 가능토록 하여 제품의 구분을 용이하게 하고 다양성을 확보할 수 있도록 개선된 난연특성과 멀티칼라 구현이 가능한 전기자동차용 엔지니어링 플라스틱 조성물 제조방법을 제공함에 그 주된 목적이 있다.The present invention was created to solve the above-mentioned problems in the prior art in consideration of the above-mentioned problems in the prior art. It is possible for synthetic resin products used as batteries and peripheral parts in battery-based electric vehicles to secure a flame retardant UL94 V0 rating while preventing hazards to the human body.

이때, 상기 난연제와 수지원료 혼합단계는 PA66-GF30: 40중량%, PBT-GF30: 40중량% 및 AlC12H30P3O6: 20중량%의 비율로 혼합되고; 상기 혼합단계를 거쳐 혼합된 혼합물 100중량부에 대해, 안료 1-1.5중량부 더 첨가되는 것에도 그 특징이 있다.At this time, in the step of mixing the flame retardant and the resin raw material, PA66-GF30: 40% by weight, PBT-GF30: 40% by weight, and AlC 12 H 3 0P 3 O 6 : 20% by weight are mixed; Another feature is that 1-1.5 parts by weight of pigment is added to 100 parts by weight of the mixture mixed through the mixing step.

본 발명을 보다 구체적으로 설명하기 전에, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정되어서는 아니되며, 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다.Before explaining the present invention in more detail, the terms or words used in the specification and claims should not be limited to their common or dictionary meanings, and the concepts of the terms should be appropriately used to explain the invention in the best way. It must be interpreted as meaning and concept consistent with the technical idea of the present invention based on the principle of definability.
본 발명에 따른 난연특성과 멀티칼라 구현이 가능한 전기자동차용 엔지니어링 플라스틱 조성물 제조방법은 난연제 준비단계, 수지원료 준비단계, 난연제와 수지원료 혼합단계를 포함한다.The method of manufacturing an engineering plastic composition for electric vehicles capable of implementing flame retardant properties and multicolor according to the present invention includes a flame retardant preparation step, a resin raw material preparation step, and a flame retardant and resin raw material mixing step.
이때, 난연제 준비단계는 인을 함유한 인계난연제를 사용하되, AlC12H30P3O6(Diethylphosphinic acid aluminum salt)를 사용하는 것이 특징이다.At this time, the flame retardant preparation step is characterized by using a phosphorus-based flame retardant containing phosphorus, and using AlC 12 H 3 0P 3 O 6 (Diethylphosphinic acid aluminum salt).
이러한 AlC12H30P3O6는 아래 표 1과 같은 물성을 갖는다.This AlC 12 H 3 0P 3 O 6 has the physical properties shown in Table 1 below.
본 발명에서 난연제로 사용되는 상기 AlC12H30P3O6는 Ph 5-7로서 장치의 부식성과 수지의 열화가 거의 없고, 초산냄새를 용출하지 아니하며 수지 접착력을 높이고, 무엇보다도 유해물질이 전혀 포함되어 있지 않아 RoHS, PEACH 등의 환경규제로부터 자유로울 뿐만 아니라, 인체 무해성으로 인해 환경친화적이 특성이 있다.The AlC 12 H 3 0P 3 O 6 used as a flame retardant in the present invention has a Ph of 5-7, which causes almost no corrosion of the device and deterioration of the resin, does not elute acetic acid odor, increases resin adhesion, and above all, contains no harmful substances. Since it is not contained, it is not only free from environmental regulations such as RoHS and PEACH, but is also environmentally friendly as it is harmless to the human body.
이와 같은 AlC12H30P3O6는 백색분말 형태를 띠며, 특히 본 발명에서는 수지와의 상용성을 높이기 위해 상기 AlC12H30P3O6 100중량부에 대해 폴리비닐알콜(PVA)을 40중량부 첨가 혼합, 교반하여 AlC12H30P3O6를 PVA로 코팅하여 사용하면 더욱 좋다.This AlC 12 H 3 0P 3 O 6 is in the form of a white powder, and in particular, in the present invention, to increase compatibility with the resin, polyvinyl alcohol (PVA) is added to 100 parts by weight of the AlC 12 H 3 0P 3 O 6 It is better to add 40 parts by weight, mix, stir, and coat AlC 12 H 3 0P 3 O 6 with PVA.
특히, AlC12H30P3O6는 후술되는 수지의 기계적 물성(특히, 마모저항성)을 저하시키지 않는 특성도 있어 매우 유용하다.In particular, AlC 12 H 3 0P 3 O 6 is very useful because it has the property of not deteriorating the mechanical properties (particularly wear resistance) of the resin, which will be described later.
한편, 수지원료 준비단계는 배터리 및 이와 관련된 부품들로 성형되어야 하므로 높은 내열성과 내후성, 치수안정성 등을 가져야 한다.Meanwhile, the resin raw material preparation stage must have high heat resistance, weather resistance, and dimensional stability since it must be molded into batteries and related parts.
이를 위해, 본 발명에서는 PA(Polyamide)66-GF30을 사용한다. 이 경우, GF는 글라스화이버로서 유리섬유를 의미한다.For this purpose, the present invention uses PA (Polyamide)66-GF30. In this case, GF refers to glass fiber.
또한, 본 발명은 PBT(Polybuthleneterephthalate)-GF30도 사용하는데, 이들은 1:1의 중량비로 혼합됨이 바람직하다.In addition, the present invention also uses PBT (Polybutleneterephthalate)-GF30, and they are preferably mixed at a weight ratio of 1:1.
이때, PA66-GF30은 유리섬유가 30wt% 충전되어 강화된 PA66으로서 높은 강도, 강성유지 및 높은 크리프성(Creep), 치수안정성을 확보하고, 자외선 차단성과 내후성을 높이기 위해 사용된다.At this time, PA66-GF30 is a reinforced PA66 filled with 30wt% glass fiber and is used to maintain high strength and rigidity, maintain high creep resistance, ensure dimensional stability, and increase UV protection and weather resistance.
다만, 마모저항성이 떨어지는 단점이 있다.However, it has the disadvantage of low wear resistance.
그리고, PBT-GF30은 유리섬유가 30wt% 충전되어 강화된 PBT로서 고내열성과 고강도 특성 및 고내구성 확보를 위해 사용된다.In addition, PBT-GF30 is a reinforced PBT filled with 30wt% glass fiber and is used to ensure high heat resistance, high strength, and high durability.
특히, 이들 수지를 사용하는 이유는 안료와의 배합성과 상보성을 통해 멀티칼라 구현을 방해하지 않도록 하기 위함이다.In particular, the reason for using these resins is to avoid interfering with the realization of multicolor through compatibility and complementarity with pigments.
다른 한편, 난연제와 수지원료 혼합단계는 PA66-GF30: 40중량%, PBT-GF30: 40중량% 및 AlC12H30P3O6: 20중량%의 비율로 혼합되는 단계이다.On the other hand, the flame retardant and resin raw material mixing step is a step in which PA66-GF30: 40% by weight, PBT-GF30: 40% by weight, and AlC 12 H 3 0P 3 O 6 : 20% by weight are mixed.
이렇게 함량을 한정하는 이유는 PA66-GF30과 PBT-GF30은 서로 1:1의 중량비로 혼합되어 상보기능을 유지하고 안료를 혼합하여 칼라를 구현할 때 칼라의 발현을 방해하지 않도록 하기 위함이며, 거기에 난연제가 혼합되면서 상호 결합되어 난연성 증대 및 마모성 강화를 유지하도록 하기 위함이다.The reason for limiting the content in this way is to maintain complementary functions by mixing PA66-GF30 and PBT-GF30 at a weight ratio of 1:1 and to avoid interfering with color expression when mixing pigments to create colors. This is to ensure that flame retardants are mixed and combined to maintain increased flame retardancy and enhanced wear resistance.
덧붙여, 상기 혼합단계를 거쳐 혼합된 혼합물 100중량부에 대해, 안료 1-1.5중량부를 더 첨가하여 다양한 색상, 즉 멀티칼라를 구현할 수 있다.In addition, for 100 parts by weight of the mixture mixed through the above mixing step, 1-1.5 parts by weight of pigment can be added to achieve various colors, that is, multicolor.
이 경우, 바람직한 멀티칼라 구현용 안료는 오렌지, 그레이, 블랙 등이 될 수 있으며, 특별히 한정하지 않는다.In this case, preferred pigments for realizing multicolor may be orange, gray, black, etc., and are not particularly limited.
다만, 그레이의 경우 TiO2, ZnS를 사용할 수 있다.However, in the case of gray, TiO 2 and ZnS can be used.
또한, 상기 혼합단계를 거쳐 혼합된 혼합물 100중량부에 대해, 디메틸벤질리덴솔비톨 10중량부, 무수말레인산 10중량부를 더 첨가하여 수지와 난연제 사이의 결합력을 높이고, 성형품의 마모저항성이 저하되는 것을 방지하도록 할 수 있다.In addition, for 100 parts by weight of the mixture mixed through the above mixing step, 10 parts by weight of dimethylbenzylidene sorbitol and 10 parts by weight of maleic anhydride are further added to increase the bonding strength between the resin and the flame retardant and prevent the abrasion resistance of the molded product from decreasing.

특히, 무수말레인산(Maleic anhydride)은 수축변형성도 억제하는 효과를 제공한다.In particular, maleic anhydride provides the effect of suppressing shrinkage deformability.
이와 같은 제조방법에 따라 난연성 테스트를 위해 UL94 시험방법에 따라 1.6mm, 3.2mm 두께의 시편을 만들고 난연성을 테스트하였다.To test flame retardancy according to this manufacturing method, specimens with a thickness of 1.6 mm and 3.2 mm were made according to the UL94 test method and tested for flame retardancy.
이때, 난연제는 10중량%, 20중량%, 30중량%로 나누어 함유시켰다.At this time, the flame retardant was divided into 10% by weight, 20% by weight, and 30% by weight.
시험결과, 10중량%는 2가지 두께 모두 V-1 등급으로 본 발명이 목적하는 V-0에는 도달하지 못하였다.As a result of the test, 10% by weight was rated V-1 for both thicknesses and did not reach the V-0 target of the present invention.
그러나, 20중량%와 30중량%를 함유시킨 시편에서는 2가지 두께 모두 V-0 등급을 만족시켰다. 다만, 30중량%의 경우에는 과다 첨가함으로 인해 수지 성분이 상대적으로 함량이 줄어들게 되어 내후성, 내열성, 수축저항성이 떨어질 우려가 있으므로 20중량%로 함유시키는 것이 가장 바람직하다고 판단되었다.However, in the specimens containing 20% and 30% by weight, both thicknesses satisfied the V-0 grade. However, in the case of 30% by weight, the content of the resin component is relatively reduced due to excessive addition, and there is a risk that weather resistance, heat resistance, and shrinkage resistance may be reduced, so it was judged that it was most desirable to contain it at 20% by weight.
