Description
본 발명은 열가소성 폴리우레탄수지(TPU) 조성물에 관한 것으로, 특히 카렌다가공이 가능한 카렌다 가공용 폴리우레탄수지(TPU) 조성물에 관한 것이다.The present invention relates to a thermoplastic polyurethane resin (TPU) composition, and more particularly to a calendar processing polyurethane resin (TPU) composition capable of calender processing.
자동차 내장재, 예컨대 인스트루먼트 판넬(Instrument Panel), 도어 트림 판넬(Door Trim Panel), 헤드라이닝(Headlining) 등의 표피재로서는 PVC(Polyvinyl chloride) 혹은 PVC/ABS 얼로이 압출 시이트나 캘린더 가공 시이트가 널리 사용되어 왔다. Automotive interior materials such as instrument panel, door trim panel, headlining, etc. are widely used for PVC (polyvinyl chloride) or PVC / ABS alloy extrusion sheets or calendered sheets. Has been.
그러나, 카렌다 가공용 PVC수지의 경우 PVC수지, 가소제, 안정제, 가공조제 및 활제류 등의 첨가로 소각 시 염소가스, SOX, 다이옥신 및 NOX등의 유해물질이 발생하여 대기오염의 원인이 되고 있다.However, in the case of calender processing PVC resin, harmful substances such as chlorine gas, SOX, dioxin and NOX are generated during incineration due to the addition of PVC resin, plasticizer, stabilizer, processing aid and lubricant.
따라서, 근년에 들어와서는 환경친화성, 리사이클(Recycle)성, 경량성, 담가(Fogging) 및 냄새 등에서 유리한 올레핀계 열가소성 일래스토머 시이트(TPO Sheet)로의 대체를 위한 연구가 활발히 진행 중에 있다. Therefore, in recent years, research is being actively conducted to replace olefinic thermoplastic elastomer sheets (TPO Sheets), which are advantageous in terms of environmental friendliness, recycling, light weight, fogging and odor.
하지만 상기 올레핀계 열가소성 일래스토머 수지의 경우 EPDM(Ethylene-Propylene-Diene Monomer)과 같은 올레핀 공중합체 고무의 가공을 돕기 위한 프로세싱 오일의 함유로 인해 캘린더 가공성이 현저히 떨어지고 낮은 용융장력(Melt Strength)으로 인해 진공성형(Vacuum Thermoforming) 등의 2차 가공성이 떨어져 심도비가 큰 부품의 경우 적용상 어려움이 따른다. However, in the case of the olefin-based thermoplastic elastomer resin, calender processability is significantly lowered due to the inclusion of processing oil to help process the olefin copolymer rubber such as EPDM (Ethylene-Propylene-Diene Monomer), and the melt strength is low. Due to the secondary workability, such as vacuum thermoforming, the application is difficult in the case of parts having a large depth ratio.
또한, 캘린더 가공성을 향상시킬 목적으로 프로세싱 오일의 함량을 비교적 적게 하고 가교구조를 갖는 EPDM의 가교도를 향상시키게 되면 원단의 표면이 거칠어지는 문제가 발생되었고, 또 가교구조를 갖는 EPDM의 가교도를 낮게 하면 캘린더 가공시 롤(Roll) 표면에 접착되어 가공을 할 수 없게 되는 문제가 발생되었다.In addition, if the content of the processing oil is relatively low and the degree of crosslinking of the EPDM having a crosslinked structure is improved for the purpose of improving calenderability, a problem occurs that the surface of the fabric is roughened. When calendering, there was a problem in that it could not be processed due to adhesion to the roll surface.
또한 TPO의 경우 상용성 있는 첨가제의 한계로 본질적으로 가공성이 열악하고, 무극성이므로 표면장력이 낮아 표면처리에 한계가 있다는 단점이 지적된다.In addition, in the case of TPO, it is pointed out that there is a limitation in surface treatment due to its low surface tension because it is inherently poor in workability due to the limitation of compatible additives and nonpolar.
이상과 같은 PVC 및 TPO의 단점을 보완할 수 있는 환경친화적인 소재로서 열가소성 폴리우레탄 엘라스토머인 TPU가 알려져 있다. TPU, a thermoplastic polyurethane elastomer, is known as an environmentally friendly material that can compensate for the above disadvantages of PVC and TPO.
오래 전 부터, TPU는 내마모성이 우수하고, 인장강도, 신장율, 내피로성 등의 기계적 성질이 뛰어나며, 내굴곡성, 내한성 및 내유성이 우수한 것으로 알려져 있다. For a long time, TPU has been known to have excellent wear resistance, excellent mechanical properties such as tensile strength, elongation rate and fatigue resistance, and excellent flex resistance, cold resistance and oil resistance.
TPU가 이상과 같은 우수한 성질을 가졌음에도 불구하고 PVC나 TPO의 대체소재로 될 수 없었던 가장 큰 이유는 엔지니어링 플라스틱으로서는 상대적으로 내열, 내광성이 좋지 않고, 응집성이 높고 극성이 강해 접착성(점착성)이 강한 성질을 지녔기 때문이다. Despite the excellent properties of TPU, the biggest reason why it could not be replaced with PVC or TPO is that engineering plastics have relatively poor heat and light resistance, high cohesiveness, and high polarity. Because of its strong nature.
따라서 대량 생산설비인 카렌다가공 시 롤 점착현상이 발생하여 생산이 어렵고 자연적으로 제조 단가가 PVC, TPO 카렌다 성형품에 비해 고가이며, 이로 인해 TPU는 압출, 사출 성형품이 대부분을 차지한다.Therefore, it is difficult to produce due to the roll adhesion phenomenon during calendar processing, which is a mass production facility, and the manufacturing cost is naturally higher than that of PVC and TPO calendar molded products, and thus, TPU takes the majority of extrusion and injection molded products.
이에 본 발명은 상기의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 카렌다(CALENDER)가공성이 우수한 TPU 조성물을 제공함에 있다. Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a TPU composition excellent in calender (CALENDER) processability.
상기의 목적을 달성하기 위해 본 발명은 TPU에 안정제 및 기타 첨가제를 적절히 배합하여 TPU의 고유의 특성인 탄성을 유지하면서, 내열, 내광성을 개선하고 카렌다 가공시 롤 접착 문제를 해소하여 대량생산이 가능한 카렌다(CALENDER)가공성이 우수한 TPU 조성물을 제공한다.In order to achieve the above object, the present invention is capable of mass production by appropriately blending stabilizers and other additives to the TPU while maintaining elasticity, which is an inherent characteristic of the TPU, improving heat resistance and light resistance, and solving roll adhesion problems during calender processing. Provided is a TPU composition excellent in calenderability.
구체적으로 본 발명에 따른 카렌다(CALENDER)가공성이 우수한 TPU 조성물은 TPU수지 35 ~ 80 중량부, 충진제(CaCo3) 6 ~ 15 중량부, ABS 수지 6 ~ 22 중량부, SAN 수지 0 ~ 20 중량부, NBR 수지 2 ~ 7 중량부, 활제(Ca-St) 2중량부 및 충격보강제(아크릴레이트 고무) 4 ~ 7 중량부를 포함하는 것을 특징으로 한다.Specifically, the TPU composition having excellent calenderability according to the present invention includes 35 to 80 parts by weight of TPU resin, 6 to 15 parts by weight of filler (CaCo 3 ), 6 to 22 parts by weight of ABS resin, and 0 to 20 parts by weight of SAN resin. , 2 to 7 parts by weight of NBR resin, 2 parts by weight of lubricant (Ca-St) and 4 to 7 parts by weight of impact modifier (acrylate rubber).
이상과 같은 조성을 갖는 본 발명의 TPU 조성물은 TPU의 고유의 특성인 탄성을 유지되면서, 내열, 내광성이 우수하고, 무엇 보다도 카렌다 가공 시 롤 접착 문제를 해소하여 대량생산이 가능하게 된다.The TPU composition of the present invention having the composition as described above is excellent in heat resistance and light resistance while maintaining elasticity, which is an inherent characteristic of the TPU, and above all, mass production is possible by solving roll adhesion problems during calendar processing.
상기에서 첨가되는 TPU수지가 35중량부이하이면 탄성 및 기계적 성질이 저하되고, 반대로 80중량부를 초과하게 되면 카렌다 가공 시 롤 점착이 증가하는 경향이 있으며, 내광성, 내열성이 저하하는 문제점이 있다.When the TPU resin added above is 35 parts by weight or less, the elasticity and mechanical properties are lowered. On the contrary, when the TPU resin is more than 80 parts by weight, roll adhesion tends to increase during calendering, and light resistance and heat resistance may be lowered.
또한 ABS 수지와 SAN 수지는 각각 6 ~ 22 중량부 및 0 ~ 20 중량부로 본 발명의 조성물에 첨가되는 것이 바람직한데 그 이유는 ABS 수지 또는 SAN 수지 어느 한 성분이 상기 수치범위의 상한을 초과하게 되면 탄성 및 기계적 물성이 저하되고 가공온도가 상승하여 롤 점착현상이 발생할 수 있으며, 그 하한에 미치지 못하게 되면 역시 가공시 롤 점착현상이 발생할 수 있기 때문이다.In addition, the ABS resin and the SAN resin are preferably added to the composition of the present invention at 6 to 22 parts by weight and 0 to 20 parts by weight, respectively, because if either component of the ABS resin or the SAN resin exceeds the upper limit of the numerical range, This is because the elasticity and mechanical properties are lowered and the processing temperature is increased, so that the adhesion of the roll may occur, and if it does not reach the lower limit, the adhesion of the roll may occur during processing.
TPU수지의 탄성을 보조하는 역할을 하는 NBR 수지의 경우는 본 발명의 조성물에 2 ~ 7 중량부로 참여되는데 첨가량이 2중량부 이하가 되면 TPU수지의 탄성보조역할이 안되고, 카렌다 가공시 롤 점착현상을 발생시키는 원인이 되며, 첨가량이 7중량부를 초과하게 되면 제품의 표면상태가 불량하게 되고, 가공 시 용융온도가 상승하는 경향이 있다.In the case of NBR resin, which serves to assist the elasticity of the TPU resin, the composition of the present invention participates in 2 to 7 parts by weight, but when the amount is 2 parts by weight or less, the elastic auxiliary role of the TPU resin is not provided, and the roll adhesion phenomenon during calendar processing When the addition amount exceeds 7 parts by weight, the surface state of the product is poor, the melting temperature tends to increase during processing.
충진제(CaCo3) 및 충격보강제의 경우는 각각 6 ~ 15 중량부 및 4 ~ 7중량부로 첨가되는데 어느 것이나 상기 수치범위를 초과하게 되면 제품의 탄성 및 기계적 물성이 저하하게 되고 그 이하에서는 가공 시 롤 점착현상이 발생하며 가공 후 제품끼리 상호 점착하는 현상이 발생한다. 또한 충격보강제의 경우 4중량부 이하에서는 내광성 및 내후성이 저하되는 경향이 있다.Fillers (CaCo 3 ) and impact modifiers are added in the range of 6 to 15 parts by weight and 4 to 7 parts by weight, respectively. If any of these exceeds the above numerical range, the elasticity and mechanical properties of the product deteriorate. Adhesion occurs and the products stick together after processing. In the case of the impact modifier, light resistance and weather resistance tend to be lowered at 4 parts by weight or less.
이하 실시예를 설명한다.Examples will be described below.
TPU수지 65 중량부, CaCo3 10 중량부, ABS 수지 15 중량부, SAN 수지 15 중량부, NBR 수지 5 중량부, 활제(Ca-St) 2 중량부 및 충격보강제로서 아크릴레이트 고무 5 중량부를 포함하는 TPU 조성물을 건조 블렌딩하고 이를 펠렛으로 제조하였다. 그런 다음 8인치 롤밀을 이용하여 200℃에서 쉬트(SHEET)가공 하여 내열성 및 내광성, 카렌다 가공 시 작업성(점착성)을 육안으로 관찰하였다.65 parts by weight of TPU resin, 10 parts by weight of CaCo 3 , 15 parts by weight of ABS resin, 15 parts by weight of SAN resin, 5 parts by weight of NBR resin, 2 parts by weight of lubricant (Ca-St) and 5 parts by weight of acrylate rubber as an impact modifier. TPU composition was dry blended and made into pellets. Then, the sheet (SHEET) processing at 200 ℃ using an 8 inch roll mill to observe the heat resistance and light resistance, workability (adhesiveness) during calendar processing with the naked eye.
사용한 TPU 수지는 SHORE A 경도계로 70 - 85 그레이드인 것을 사용였고, ABS 수지는 부타디엠 함량이 35 - 45%되는 것을, SAN 수지는 아크릴로니트릴 함량이 20 - 40% 되는 것을 사용하였다.The TPU resin used was a grade of 70-85 with a SHORE A hardness meter, the ABS resin used 35-45% butadiem content, and the SAN resin used 20-40% acrylonitrile content.
내열성은 110℃에서 7일간 방치 후 변색을 그레일스케일(GRAY SCALE)로 관찰하였고, 내광성은 자외선 컨덴서(UV CONDENSER)에서 60℃로 200시간 방치 후 색 변색을 그레일스케일(GRAY SCALE)로 관찰하였다.Heat resistance was observed after 7 days at 110 ℃ gray scale (GRAY SCALE), light resistance was observed after 60 hours at 60 ℃ in an ultraviolet condenser (UV CONDENSER) color fading observed in gray scale (GRAY SCALE) It was.
비교예의 것으로는 현재 사용되고 있는 PVC제품을 사용하였다.As a comparative example, the PVC product currently used was used.
시험결과 내열성 및 내광성의 경우 실시예 및 비교예 모두 양호한 것으로 나타났으나 카렌다 가공 시 점착현상은 본 발명예인 실시예에서는 발생하지 않았고 비교예에서만 발생하였다.As a result of the test, both heat resistance and light resistance were found to be satisfactory in both Examples and Comparative Examples. However, adhesion was not occurred in the Examples of the present invention but only in the Comparative Examples.
이상 설명한 본 발명에 따르면, 내열성 및 내광성이 우수하면서도 가공 시 롤 점착현상이 발생하지 않아 카렌다 가공에 의한 대량생산이 가능한 TPU조성물이 제공된다.According to the present invention described above, there is provided a TPU composition which is excellent in heat resistance and light resistance, but does not generate roll adhesion during processing, thereby enabling mass production by calender processing.
