Description
본 발명은 아크릴로니트릴-부타디엔-스티렌 수지 조성물에 관한 것으로, 더욱 상세하게는 저광택 고충격 특성을 지니는 내열 아크릴로니트릴-부타디엔-스티렌 수지 조성물에 관한 것이다. The present invention relates to an acrylonitrile-butadiene-styrene resin composition, and more particularly, to a heat-resistant acrylonitrile-butadiene-styrene resin composition having low gloss and high impact characteristics.
아크릴로니트릴-부타디엔-스티렌(Acrylonitrile-Butadiene-Styrene, 이하 'ABS'라 함) 수지는, 내화학 약품성을 부여하는 아크릴로니트릴(Acrylonitrile)과 내충격성을 주는 고무(Butadiene Rubber) 및 성형성을 향상시키는 스티렌(Styrene)의 세 가지 성분으로 이루어진 수지이다. 용도에 따라 이 세 가지 성분 이외에 다른 성분을 추가하여 사용하기도 한다. Acrylonitrile-Butadiene-Styrene (hereinafter referred to as 'ABS') resins include acrylonitrile, which imparts chemical resistance, buttadiene rubber, and moldability. It is a resin composed of three components of styrene (Styrene) to improve. Depending on the application, other components may be added in addition to these three components.
일반적으로 ABS수지는 성형가공성, 내약품성, 높은 기계적 강도, 내충격성 등 각종 특성이 우수하여 가전제품이나 사무기기에 널리 사용되고 있다. In general, ABS resin is widely used in home appliances and office equipment because of its excellent properties such as molding processability, chemical resistance, high mechanical strength and impact resistance.
특히, 그 중에서도 α-메틸스티렌계 내열 공중합체 또는 페닐말레이미드계 내열 공중합체를 포함하는 내열 ABS는 획기적으로 향상된 높은 내열도로 인하여 최근에 자동차 소재 및 각종 내외장제 용으로 그 응용범위 및 사용량이 꾸준히 증가하고 있다. In particular, heat-resistant ABS including α-methylstyrene-based heat-resistant copolymer or phenylmaleimide-based heat-resistant copolymer has recently been used steadily in its application range and amount of use for automobile materials and various interior and exterior agents due to its significantly improved heat resistance. It is increasing.
그러나 일반적인 내열 ABS는 사출시 표면의 평활도가 낮아 빛을 산란시키지 못하여 높은 광택을 갖게 된다는 문제점이 있어서, 이를 개선하고자 하는 시도들이 계속되고 있다.However, the general heat-resistant ABS has a problem that it has a high gloss because it does not scatter light due to the low smoothness of the surface during injection, attempts to improve this continues.
또한, 최근 감성품질에 대한 요구가 증가하면서 무광택 수지 조성물 개발이 더욱 활기를 띠고 있다. 이러한 시도는 다음 세 가지, 즉, 대입경 고무입자를 사용하거나, 크기가 큰 무기 충진제(Filler)를 투입하거나, 또는 저광 목적의 첨가제를 투입하는 방법으로 대별될 수 있다. In addition, with the recent increase in the demand for emotional quality, the development of matte resin compositions has become more vibrant. This approach can be roughly categorized into the following three methods: using large particle rubber particles, adding a large inorganic filler, or adding an additive for low light.
이 중 대입경 고무 입자를 사용하는 방법의 경우, 은은하고 부드러운 감성적인 제품을 얻을 수 있으나, 전체적인 저광 효과는 뛰어나지 않은 편이며 충격강도가 좋지 않다는 문제점이 있었다. 또한 고무가 빛 또는 열 등에 영향을 많이 받기 때문에, 내후성, 내열성과 같은 물성이 좋지 않다는 문제점도 있었다. In the case of using a large particle rubber particles, a soft and soft emotional product can be obtained, but the overall low light effect is not excellent and the impact strength is not good. In addition, since the rubber is much affected by light or heat, there is also a problem that physical properties such as weather resistance and heat resistance are not good.
또한, 크기가 큰 무기 충진제를 투입할 경우에는 충격 강도 등의 물성 저하가 심각하며, 저광 발현을 위한 첨가제를 투입할 경우에는 소량 투입으로 저광 실현이 가능하지만, 투박하고 거친 느낌의 저광으로 감성적인 면을 크게 해칠 수 있다는 문제점이 있었다.In addition, when a large inorganic filler is added, physical properties such as impact strength are severely deteriorated, and when an additive for low light expression is added, low amount of light can be realized by adding a small amount, but it is sensitive to low light with a rough and rough feeling. There was a problem that can greatly hurt the noodles.
특히, 상기와 같은 저광 발현을 위한 첨가제를 투입하는 경우의 구체적인 예로는, 대한민국 특허 제10-0508145호 및 특허 제 10-0528779호 등록공보 등에 개시 되어 있다. Particularly, in the case of adding the additive for low light expression as described above, it is disclosed in the Republic of Korea Patent No. 10-0508145 and Patent No. 10-0528779.
그러나, 이들과 같이 무광택충진제용 아크릴로니트릴 또는 무광택충진제용 스티렌아크릴로니트릴 중합체를 첨가하거나, 혹은 아실 퍼옥사이드계 화합물과 같은 가교첨가제를 첨가하는 경우, 저광택 효과가 미미할 뿐만 아니라, 충격강도 및 내열성이 크게 하락하는 단점이 있었다.However, when adding acrylonitrile for matte fillers or styrene acrylonitrile polymers for matte fillers or crosslinking additives such as acyl peroxide compounds as described above, the low gloss effect is insignificant, and the impact strength and heat resistance There was a downside to this drastic fall.
이에 더하여, 대한민국 특허 제 10-0528779호에 개시된 방법의 경우, ABS 구성물의 제조 공정을 조절하여 입자경과 겔 함량 등을 조절하므로, 부가적인 제조 공정의 추가를 유발하여 생산 단가가 매우 올라가게 된다는 단점도 있었다. In addition, the method disclosed in the Republic of Korea Patent No. 10-0528779, by adjusting the manufacturing process of the ABS component to control the particle size and gel content, etc., causing the addition of an additional manufacturing process to increase the production cost very high There was also.
그리하여, 내열 ABS 수지의 저광택 효과를 얻을 수 있으면서도 내열성 및 충격강도를 내열 ABS와 동등수준으로 유지하거나, 혹은 더욱 높일 수 있는 수지 조성물에 대한 개발이 절실히 요구되고 있는 실정이다. Therefore, while the low gloss effect of the heat resistant ABS resin can be obtained, development of a resin composition capable of maintaining or increasing the heat resistance and impact strength at the same level as the heat resistant ABS is urgently required.
상기와 같은 문제점을 해결하기 위하여, 본 발명은 효율적인 무광택용 첨가제를 적정량으로 첨가함으로써 저광택 효과를 극대화시킬 수 있는 한편, 충격강도를 오히려 향상시키고 내열도를 유지할 수 있는 내열 ABS 수지 조성물을 제공하는 것에 그 목적이 있다.In order to solve the above problems, the present invention is to provide a heat-resistant ABS resin composition that can maximize the low gloss effect by adding an appropriate amount of an additive for the matte, while improving the impact strength and maintain the heat resistance The purpose is.
본 발명의 또 다른 목적은 상기 조성물을 사용하여 제조되는 저광택 고충격 특성을 지니는 내열 플라스틱 성형품을 제공하는 것이다.Another object of the present invention is to provide a heat-resistant plastic molded article having low gloss and high impact characteristics produced using the composition.
상기와 같은 목적을 달성하기 위하여, 본 발명은 그라프트 아크릴로니트릴-부타디엔-스티렌 중합체 10 내지 50 중량부; 내열 스티렌-아크릴로니트릴 50 내지 90 중량부; 및 가교 스티렌-아크릴로니트릴 0.5 내지 5 중량부를 포함하는 아크릴로니트릴-부타디엔-스티렌 수지 조성물을 제공한다.In order to achieve the above object, the present invention is 10 to 50 parts by weight of graft acrylonitrile-butadiene-styrene polymer; 50 to 90 parts by weight of heat resistant styrene-acrylonitrile; And it provides an acrylonitrile-butadiene-styrene resin composition comprising 0.5 to 5 parts by weight of crosslinked styrene-acrylonitrile.
또한, 본 발명은 상기 수지조성물을 사용하여 제조되는 플라스틱 성형품을 제공한다.The present invention also provides a plastic molded article produced using the resin composition.
이하에서 본 발명의 구성을 더욱 상세하게 설명한다.Hereinafter, the configuration of the present invention in more detail.
본 발명은 그라프트 아크릴로니트릴-부타디엔-스티렌 중합체 10 내지 50 중량부; 내열 스티렌-아크릴로니트릴 50 내지 90 중량부; 및 가교 스티렌-아크릴로니트릴 0.5 내지 5 중량부를 포함하는 아크릴로니트릴-부타디엔-스티렌 수지 조성물을 제공한다.The present invention is 10 to 50 parts by weight of graft acrylonitrile-butadiene-styrene polymer; 50 to 90 parts by weight of heat resistant styrene-acrylonitrile; And it provides an acrylonitrile-butadiene-styrene resin composition comprising 0.5 to 5 parts by weight of crosslinked styrene-acrylonitrile.
우선, 본 발명에 의한 조성물은 그라프트 ABS 중합체 10 내지 50 중량부를 포함한다. 상기 그라프트 ABS 중합체의 함량이 10 중량부 미만일 경우에는 저온 내충격성이 하락하게 되고, 50 중량부를 초과할 경우에는 생산공정이 불안정해지는 문제점이 발생하므로, 그라프트 ABS 중합체의 함량은 10 내지 50 중량부가 바람직하다. First, the composition according to the present invention comprises 10 to 50 parts by weight of the graft ABS polymer. When the content of the graft ABS polymer is less than 10 parts by weight, the low-temperature impact resistance is lowered, and when the content of the graft ABS polymer is more than 50 parts by weight, the production process may become unstable. Thus, the content of the graft ABS polymer is 10 to 50% by weight. Addition is preferred.
상기 그라프트 ABS 중합체는 폴리부타디엔 고무 라텍스 40 내지 60 중량부, 방향족 비닐계 화합물 20 내지 40 중량부 및 비닐시안화합물 0.1 내지 40 중량부를 공중합시킨 것이 바람직하다.The graft ABS polymer is preferably a copolymer of 40 to 60 parts by weight of polybutadiene rubber latex, 20 to 40 parts by weight of aromatic vinyl compound, and 0.1 to 40 parts by weight of vinyl cyan compound.
이때, 상기 폴리부타디엔 고무 라텍스는 평균 입경이 2900Å이며, 겔 함량이 70 ~ 80%가 바람직하다. 이와 같은 범위를 벗어나는 경우, 충격특성을 낮추거나, 광택 특성에 나쁜 영향을 주게 되어 바람직하지 않게 된다.At this time, the polybutadiene rubber latex has an average particle diameter of 2900Å, the gel content is preferably 70 to 80%. If it is out of this range, the impact characteristics are lowered or the gloss characteristics are adversely affected, which is undesirable.
또한, 본 발명에 의한 조성물은 내열 스티렌-아크릴로니트릴(이하, 'SAN'이라 함) 50 내지 90 중량부를 포함한다. In addition, the composition according to the present invention contains 50 to 90 parts by weight of heat-resistant styrene-acrylonitrile (hereinafter referred to as 'SAN').
상기 내열 SAN은 비닐계 화합물과 비닐시안화합물의 공중합체 35 내지 60 중량부와 비닐계 화합물과 페닐말레이미드계 화합물 40 내지 65 중량부를 중합시킨 것이거나, 혹은 비닐계 화합물과 비닐시안화합물의 공중합체 35 내지 60 중량부와 비닐계 화합물과 α-메틸스티렌계 화합물의 공중합체 40 내지 65 중량부를 공중합시킨 것이 바람직하다.The heat-resistant SAN is a polymer obtained by polymerizing 35 to 60 parts by weight of a copolymer of a vinyl compound and a vinyl cyan compound and 40 to 65 parts by weight of a vinyl compound and a phenylmaleimide compound, or a copolymer of a vinyl compound and a vinyl cyan compound It is preferable to copolymerize 35-60 weight part, 40-65 weight part of copolymers of a vinyl type compound and the (alpha) -methylstyrene type compound.
이때, 상기 비닐계 화합물과 비닐시안화합물의 공중합체는 비닐계 화합물 55 내지 80 중량부와 비닐시안화합물 20 내지 45 중량부를 공중합시킨 것이 바람직하다.In this case, it is preferable that the copolymer of the vinyl compound and the vinyl cyan compound copolymerize 55 to 80 parts by weight of the vinyl compound and 20 to 45 parts by weight of the vinyl cyan compound.
이때, 상기 비닐계 화합물과 페닐말레이미드계 화합물의 공중합체는 비닐계 화합물 40 내지 65 중량부와 페닐말레이미드계 화합물 35 내지 60 중량부를 공중합시킨 것이 바람직하다.In this case, the copolymer of the vinyl compound and the phenylmaleimide compound is preferably a copolymer of 40 to 65 parts by weight of the vinyl compound and 35 to 60 parts by weight of the phenylmaleimide compound.
이때, 상기 비닐계 화합물과 α-메틸스티렌계 화합물의 공중합체는 비닐계 화합물 40 내지 65 중량부와 α-메틸스티렌계 화합물 35 내지 60 중량부를 공중합시킨 것이 바람직하다.In this case, it is preferable that the copolymer of the vinyl compound and the α-methylstyrene compound copolymerizes 40 to 65 parts by weight of the vinyl compound and 35 to 60 parts by weight of the α-methylstyrene compound.
나아가, 본 발명에 의한 조성물은 가교 SAN 0.5 내지 5 중량부를 포함한다. 상기 가교 SAN은 평균분자량이 100,000-10,000,000이 바람직하다. 특히 상기 가교 SAN으로는, Blendex BMAT(켐투라 사 제)를 사용하는 것이 바람직하다.Furthermore, the composition according to the present invention contains 0.5 to 5 parts by weight of crosslinked SAN. The crosslinked SAN preferably has an average molecular weight of 100,000-10,000,000. In particular, it is preferable to use Blendex BMAT (manufactured by Chemtura) as the crosslinked SAN.
이때, 가교 SAN은, 그라프트 ABS와 내열 SAN 100중량부를 기준으로 0.5 내지 5 중량부의 함량으로 포함되는 것이 바람직하며, 더욱 바람직하게는 3 내지 5 중량부이다. 가교 SAN의 함량이 0.5 중량부 미만인 경우 저광 효과가 매우 미미하며, 5 중량부를 초과하는 경우, 내열 ABS의 표면이 매우 거친 느낌이 들어 감성적인 면을 해칠 뿐만 아니라, 유동성 등의 일반적인 물성도 악화시키게 되므로 바람직하지 않다.At this time, the crosslinked SAN is preferably included in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the graft ABS and heat resistant SAN, and more preferably 3 to 5 parts by weight. When the content of the crosslinked SAN is less than 0.5 parts by weight, the low light effect is very slight. When the content of the crosslinked SAN is more than 5 parts by weight, the surface of the heat-resistant ABS has a very rough feeling, which not only hurts the emotional side, but also deteriorates general properties such as fluidity. This is undesirable.
상기와 같은 본 발명에 의한 수지 조성물은 통상의 방법으로 제조될 수 있다. 예를 들면, 본 발명의 구성성분을 동시에 혼합한 후에, 압출기 내에서 용융 압출하고 펠렛 형태로 제조할 수 있다.The resin composition according to the present invention as described above can be prepared by a conventional method. For example, the components of the present invention may be mixed simultaneously, then melt extruded in an extruder and prepared in pellet form.
본 발명은 또한, 상기 수지 조성물을 사용하여 제조되는 플라스틱 성형품을 제공한다. 상기 플라스틱 성형품으로는, 내열, 저광택 및 고충격 특성을 요구하는 제품이라면 특별히 한정되지 않는다고 할 것이나, 그 중에서도 자동차용 플라스틱 제품, 내외장제용 플라스틱 제품이 바람직하다. The present invention also provides a plastic molded article produced using the resin composition. The plastic molded article is not particularly limited as long as it is a product that requires heat resistance, low gloss and high impact characteristics. Among them, plastic products for automobiles and plastic products for interior and exterior agents are preferred.
이하에서는 본 발명의 바람직한 실시예를 통하여 본 발명을 보다 구체적으로 설명하기로 한다. 그러나, 본 실시예는 본 발명의 권리범위를 한정하는 것은 아니고 단지 예시로서 제시된 것이다. Hereinafter, the present invention will be described in more detail with reference to preferred embodiments of the present invention. However, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

그라프트 ABS 50중량부, 내열 SAN 50중량부, 가교 SAN(Blendex BMAT) 0중량부를 사용한 것을 제외하고는, 상기 실시예 1과 동일한 방법으로 ABS 수지 조성물을 제조하였다.ABS resin composition was manufactured in the same manner as in Example 1, except that 50 parts by weight of graft ABS, 50 parts by weight of heat-resistant SAN, and 0 parts by weight of crosslinked SAN (Blendex BMAT) were used.
시험예Test Example 1 One
상기 실시예 1~3 및 비교예 1~3에서 제조된 수지 조성물에 대하여, 사출 온도 240℃에서, 10 oz 사출기를 이용하여 용융장력 측정을 위한 시편과 물성 측정을 위한 ASTM규격 시편을 제조하였다.With respect to the resin composition prepared in Examples 1 to 3 and Comparative Examples 1 to 3, at the injection temperature 240 ℃, using a 10 oz injection machine to prepare a specimen for measuring the melt tension and ASTM standard for measuring the physical properties.
각 시편은 23℃, 상대습도 50%에서 48시간 방치한 후 열변형온도는 ASTMAfter 48 hours at 23 ℃ and 50% RH, each specimen was subjected to ASTM
D648에 의거하여, 충격강도는 ASTM D256에 의거하여, 광택도는 ASTM D523에 의거하여 각각 측정하였으며, 그 결과를 하기 표 1에 나타내었다.Based on D648, impact strength was measured according to ASTM D256, glossiness was measured according to ASTM D523, respectively, and the results are shown in Table 1 below.
상기 표 1의 결과로부터, 가교 SAN(Blendex BMAT)이 3 및 4 중량부가 첨가된 실시예 1 및 실시예 3의 경우, 가교 SAN이 전혀 첨가되지 않은 비교예 1에 비해 공히 열변형 온도는 동등 수준으로 유지되었으며, 충격강도는 20% 가량 상승하였고, 광택도는 R'60 = 25 이하의 저광이 발현됨을 알 수 있었다. From the results of Table 1, in the case of Examples 1 and 3 to which 3 and 4 parts by weight of the crosslinked SAN (Blendex BMAT) was added, the heat distortion temperature was the same level as compared with Comparative Example 1 without the addition of the crosslinked SAN at all. It was maintained as, the impact strength was increased by about 20%, the gloss was found that the low light of R'60 = 25 or less.
또한, 그라프트 ABS가 50중량부 첨가됨으로써, 다른 조성들에 비하여 충격강도가 향상된 실시예 2(가교 SAN 4중량부 포함)와 비교예 3(가교 SAN 포함되지 않음)을 비교해보더라도, 실시예 2의 경우가 열변형온도, 충격강도 및 광택도의 모든 면에서 비교예 3에 비하여 우수함을 알 수 있었다. In addition, even if compared to Example 2 (including 4 parts by weight of cross-linking SAN) and Comparative Example 3 (not including cross-linking SAN) improved impact strength compared to other compositions by adding 50 parts by weight of graft ABS, Example 2 It can be seen that is superior to Comparative Example 3 in all aspects of the heat deformation temperature, impact strength and gloss.
나아가, 가교 SAN(Blendex BMAT)이 6 중량부 첨가된 비교예 2의 경우에는, 뛰어난 저광이 발현되긴 하였으나, 사출 외관이 매우 투박하고 거칠게 나왔다.Furthermore, in the case of Comparative Example 2 to which 6 parts by weight of crosslinked SAN (Blendex BMAT) was added, although excellent low light was expressed, the appearance of the injection was very crude and rough.
따라서, 본 발명에 따라, 가교 SAN을 적정량 첨가하는 경우, 우수한 저광효과를 얻을 수 있을 뿐만 아니라, 충격강도도 향상된다는 것을 확인할 수 있었다.Therefore, according to the present invention, when an appropriate amount of crosslinked SAN was added, it was confirmed that not only an excellent low light effect was obtained, but also the impact strength was improved.
상기한 바와 같이, 본 발명에 의하는 경우, 저광택 첨가제로서, 가교 SAN을 첨가하고, 또한, 이와 같은 가교 SAN을 그라프트 ABS 및 내열 SAN 100 중량부 대비 0.5 내지 5중량부의 양으로 첨가함으로써, 광택도는 현저하게 감소시킬 수 있는 반면, 내열성은 내열 ABS와 동등 수준으로 유지할 수 있고, 충격강도는 더욱 향상시킬 수 있게 된다.As described above, in the case of the present invention, by adding a crosslinked SAN as a low gloss additive, and adding such a crosslinked SAN in an amount of 0.5 to 5 parts by weight relative to 100 parts by weight of the graft ABS and the heat resistant SAN, While the degree can be significantly reduced, the heat resistance can be maintained at the same level as the heat resistant ABS, and the impact strength can be further improved.
