본 발명은 열가소성 수지조성물에 관한 것으로, 특히 폴리우레탄과 폴리비닐 클로라이드의 배합비율을 달리함으로써 물성이 향상되어진 열가소성 수지 조성물과 그 제조방법에 관한 것이다.The present invention relates to a thermoplastic resin composition, and more particularly, to a thermoplastic resin composition having improved physical properties by varying the blending ratio of polyurethane and polyvinyl chloride, and a method of manufacturing the same.
일반적으로 열가소성 폴리우레탄 엘라스토머(Thermoplastic Polyurethane Elastomer : 이하 TPU라 한다)는 소프트 세그먼트를 구성하는 2관능 폴리올과 하드세그먼트를 구성하는 단쇄 글리콜 및 디이소시아네이트의 3성분 조합에 의해 이루어지는 블럭 공중합체로서 극성이 매우 크고, 기계적 성질이 우수하여 자동차부품이라던가 공업용품에 많이 사용되고 있다.In general, thermoplastic polyurethane elastomers (hereinafter referred to as TPUs) are block copolymers formed by a three-component combination of a bifunctional polyol constituting a soft segment and a short-chain glycol and diisocyanate constituting a hard segment and having a very polarity. It is large and has excellent mechanical properties, so it is widely used in automobile parts and industrial products.
그런데 상기 TPU를 공업적으로 이용함에 있어서는, 이 TPU가 점탄성이 크기 때문에 다단식 압연기인 캘린더롤로써 압연할때 이에 걸리는 부하가 커서 소요동력이 많다는 가공상의 문제가 있어 실제 적용되는 경우는 드물고, 대부분의 경우 T-다이를 이용하여 압출방식으로 시이트상으로 제조하고 있다.However, in the industrial use of the TPU, since the TPU has a high viscoelasticity, there is a problem in processing that the load applied to the roll by calender roll, which is a multi-stage rolling mill, is large and requires a lot of power. In this case, the sheet is manufactured by extrusion using a T-die.
그러나 TPU는 온도에 민감한 소재로서 가공시기에 따라 작업조건을 일일히 변경시켜주어야 하여 번거로울 뿐만 아니라 이와같이 작업조건을 변경시킴에 따라 제품의 두께라든가 기계적 물성이 달라지게 되어 그 품질은 물론 생산성을 향상시킬 수 없다는 결점을 갖고 있다.However, TPU is a temperature-sensitive material, and it is cumbersome to change the working conditions according to the processing time, and as the working conditions are changed, the thickness and mechanical properties of the product are changed. It has the drawback of not being able to.
한편 폴리비닐클로라이드(이하 간단히 PVC라 한다)는 전반적인 물성이 양호하며 시이트 형상 또는 파이프 형상으로 가공되어 많이 사용되고 있기는 하나, 탄성이 부족함으로해서 쿠션기능이 요구되는 물품에는 단독으로 사용할 수 없고 이에 별도의 충진재 또는 보강재를 첨가하여 사용하고 있다.On the other hand, polyvinyl chloride (hereinafter simply referred to as PVC) has good general physical properties and is often used in the form of a sheet or pipe. However, polyvinyl chloride cannot be used alone for articles requiring cushion functions due to lack of elasticity. Filler or reinforcing material is added and used.
그런데 최근에 들어 다양한 상품이 개발됨에 따라 이에 요구되는 물성도 다양화되고 있는바, 이에 단독수지가 갖는 물성의 한계를 극복하기 위해 서로 다른 수지를 배합하여 특유의 물성을 갖도록 하는 배합(blending) 기술이 제안되고 있다. 예컨대 TPU에다 폴리프로필렌이라던가 나일론, 또는 ABS수지등을 배합하는 기술이 국내에서도 실시되고 있는바, 이는 상기에서 언급한 바와 같이 TPU의 고점탄성 때문에 모두 압출 또는 사출방식으로 제조하고 있고, 또 소재의 한계성 때문에 다양한 물성을 갖는 수지조성물을 얻을 수 없다고 하는 결점이 있다.However, as various products have been developed in recent years, the physical properties required for this have been diversified. In order to overcome the limitations of the physical properties of the resin alone, a blending technology for blending different resins to have specific physical properties Is being proposed. For example, a technique of blending polypropylene, nylon, or ABS resin with TPU is being practiced in Korea. As mentioned above, all of them are manufactured by extrusion or injection method due to the high viscoelasticity of the TPU. Therefore, there is a drawback that a resin composition having various physical properties cannot be obtained.
이에 본 발명은 상기와 같은 제반 결점을 해결하기 위해 발명된 것으로, 본 발명의 목적은 TPU와 PVC를 소정비율로 배합하여 물성을 개선시킬 수 있음과 더불어 작업조건의 표준화로 생산성을 향상시킬 수 있도록 된 열가소성 수지조성물과 그 제조방법을 제공하는 것이다.Accordingly, the present invention was invented to solve the above-mentioned shortcomings, and an object of the present invention is to combine TPU and PVC at a predetermined ratio to improve physical properties and to improve productivity by standardization of working conditions. It is to provide a thermoplastic resin composition and a method for producing the same.
상기와 같은 목적을 달성하기 위한 본 발명은, 수퍼믹서기에 PVC 100중량부에 대해 프탈레이트계 가소제 50중량부 및 Ba-Zn계 액상 안정제 3-4중량부를 첨가하여 2.5-5분동안 교반하여 PVC 혼합물을 만들고, 또다른 수퍼믹서기에 TPU수지 100중량부에 대해 아크릴계 가공조제 0.5-2.0중량부와, 폴리에틸렌 왁스계 활제 0.5-1.0중량부, Zn계 안정제 0.1-0.5중량부 및 Ba계 안정제 0.1-0.5중량부를 첨가하여 교반함으로써 TPU 혼합물을 만든 다음, 이들 PVC 혼합물과 TPU 혼합물을 반버리 믹서기에 투입하여 3-4분 교반시킨 뒤, 이 혼합물을 공지의 믹싱롤과, 워밍롤를 통과시킨 다음 캘린더롤을 통해 소정칫수의 시이트상 제품을 제조하도록 구성되는바, 본 발명에서는 상기 PVC 혼합물과 TPU 혼합물을 배합비율을 10%씩 증감시키면서 0%에서 100% 범위로 서로 변화시킴으로써 다양한 물성을 갖는 열가소성 수지를 제조할 수 있도록 되어 있다.The present invention for achieving the above object is, by adding 50 parts by weight of a phthalate plasticizer and 3-4 parts by weight of Ba-Zn-based liquid stabilizer to 100 parts by weight of PVC to the supermixer and stirred for 2.5-5 minutes PVC mixture In another super mixer, 0.5-2.0 parts by weight of acrylic processing aid, 0.5-1.0 parts by weight of polyethylene wax lubricant, 0.1-0.5 parts by weight of Zn stabilizer and 0.1-0.5 parts by weight of Ba-based stabilizer based on 100 parts by weight of TPU resin. TPU mixture was prepared by adding parts by weight, followed by adding these PVC mixture and TPU mixture to a Banbury blender, stirring for 3-4 minutes, and then passing the mixture through a known mixing roll and a warming roll, followed by calender roll. It is configured to produce a sheet-like product of a predetermined dimension through the present invention, the PVC mixture and the TPU mixture by varying each other in the range of 0% to 100% while increasing or decreasing the blending ratio by 10% It is possible to manufacture a thermoplastic resin having physical properties.
이하 본 발명을 실시예를 들어 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to Examples.
본 발명에서 사용된 TPU는 부틸렌아디페이트계의 폴리에스터 타입으로 소프트세그먼트의 평균분자량이 2,000-3,000이고, 전체 디올의 -OH기와 디아소시아네이트의 -NCO기를 약 1＜NCO/on＜1.1로 반응시킨 불완전 열가소형으로 말단에 -NCO기가 남아 있는 것이다.The TPU used in the present invention is a butylene adipate-based polyester type with an average molecular weight of 2,000 to 3,000 and a -OH group of all diols and a -NCO group of diasocyanates of about 1 <NCO / on <1.1. The reaction was incomplete thermoplastic, and the -NCO group remained at the end.
다음 상기와 같은 TPU와 PVC를 배합하기 이전에 각각 소정량의 첨가제를 혼합하여 TPU 혼합물과 PVC 혼합물을 만드는바, 즉 쇼어 A경도 80±3인 TPU 수지 100중량부에 아크릴계 가공조제인 K-125 0.5-2.0중량부, 폴리에틸렌 왁스계 활제인 AC-629 0.5-1.0중량부, Zn계 안정제 0.1-0.5중량부 및, Ba계 안정제 0.1-0.5중량부를 수퍼믹서기에 투입하고 3-5분동안 교반시켜 혼합함으로써 TPU 혼합물을 만든다.Next, before mixing the TPU and PVC as described above, a predetermined amount of additives are mixed to make a TPU mixture and a PVC mixture, that is, an acrylic processing aid K-125 in 100 parts by weight of TPU resin having a Shore A hardness of 80 ± 3. 0.5-2.0 parts by weight, polyethylene wax-based lubricant AC-629 0.5-1.0 parts by weight, Zn-based stabilizer 0.1-0.5 parts by weight, Ba-based stabilizer 0.1-0.5 parts by weight into a super mixer and stirred for 3-5 minutes Mixing produces a TPU mixture.
다음 PVC(P-1300)수지 100중량부에 프탈레이트 가소제 50중량부 및 , Ba-Zn계 액상안정제 3-4중량부를 수퍼믹서기에 투입하고 2.5-5분동안 교반시켜 가소제가 PVC 수지에 충분히 흡수되게 혼합함으로써 PVC 혼합물을 만든다.Next, 50 parts by weight of a phthalate plasticizer and 3-4 parts by weight of a Ba-Zn-based liquid stabilizer were added to a super mixer in 100 parts by weight of PVC (P-1300) resin, and stirred for 2.5-5 minutes to allow the plasticizer to be sufficiently absorbed into the PVC resin. Mixing produces a PVC mixture.
이어 상기와 같이 별도로 준비된 TPU 혼합물과 PVC 혼합물을 각각 표 1에 도시된 바와 같이 중량%로 0%에서 100%까지 10%단위로 배합비율을 달리하여 반버리 믹서기에서 투입하여 3-4분동안 교반시키게 되는바, 이때 TPU는 115-125℃온도에서 반 겔링 상태가 되고, 125-130℃온도에서 TPU와 PVC 혼합물의 겔링 상태가 얻어지게 된다.Subsequently, separately prepared TPU mixture and PVC mixture, as shown in Table 1 above, were mixed in a Banbury blender with a blending ratio of 10% by weight from 0% to 100% by weight, and stirred for 3-4 minutes. In this case, the TPU is semi-gelled at a temperature of 115-125 ° C., and a gel state of the TPU and PVC mixture is obtained at a temperature of 125-130 ° C.
[표 1]TABLE 1
여기서 상기 표 1에 도시된 바와 같은 배합비율로 TPU 혼합물과 PVC 혼합물을 반버리 믹서기에서 온도 165℃, 30r.p.m속도로 혼합할때의 최대 토오크라던가 초기 겔링시간, 안정화 토오크, 또는 안정화 시간을 표 2에 도시하였다.Here, the maximum torque or initial gelling time, stabilizing torque, or stabilization time when mixing the TPU mixture and the PVC mixture at a temperature of 165 ° C. and 30 r.pm in a Banbury mixer at the mixing ratio as shown in Table 1 above 2 is shown.
[표 2]TABLE 2
표 2에 도시된 바와 같이 PVC 혼합물량이 많아짐에 따라 최대 토오크와 안정화 토오크가 감소됨과 더불어 안정화 시간이 증가하게 되는바, 이는 PVC가 TPU에 대하여 활제로서의 작용을 하게 되면서 작업온도에서의 열적 변화를 지연시키기 때문이다.As shown in Table 2, as the amount of PVC mixture increases, the maximum torque and stabilization torque are decreased, and the stabilization time is increased. This is because the PVC acts as a lubricant for the TPU, thereby changing the thermal change in the working temperature. This is because it delays.
이어 상기 각 실시예의 배합조건에 따라 TPU 혼합물과 PVC 혼합물이 겔링된 조성물을 150-155℃온도로 유지된 믹싱롤과 135-145℃온도로 유지된 워밍롤을 차례로 통과시켜 혼련시킨 뒤, 켈린더롤을 통과시켜 시이트상의 제품수지를 만든다음 이를 엠보스롤과 냉각롤을 통과시키면서 후처리를 한뒤 권취기에 감아주게 되면 본 발명에 따른 수지조성물의 제조 1사이클이 완료되게 된다.Subsequently, the composition in which the TPU mixture and the PVC mixture were gelled according to the mixing conditions of the above embodiments was kneaded by passing through a mixing roll maintained at 150-155 ° C. and a warming roll maintained at 135-145 ° C., followed by a calendar roll. After passing through to make the product resin on the sheet, and after passing through the embossing roll and the cooling roll and wound around the winding machine, the production cycle of the resin composition according to the present invention is completed.
다음에는 상기와 같이 제조된 본 발명 수지조성물의 물성을 시험하기 위해 JIS K7311방법에 따라 인장강도와, 100% 탄성계수, 신율 및 인열 강도를 측정하였고, 측정결과가 제1도 내지 제4도에 도시되어 있는바, 도표에서 실선은 시이트상 제품의 길이 방향의 물성치이고, 점선은 폭방향의 물성치이다.Next, in order to test the physical properties of the resin composition of the present invention prepared as described above, the tensile strength, 100% elastic modulus, elongation and tear strength were measured according to JIS K7311 method, and the measurement results are shown in FIGS. As shown, the solid line in the diagram is the physical property in the longitudinal direction of the sheet-like product, and the dotted line is the physical property in the width direction.
즉 제1도, 제2도에 도시된 바와 같이 PVC 혼합물에 배합하는 TPU 혼합물의 양이 증가됨에 따라 인장강도 및 신율이 점차 증가하게 되고, 인열강도는 제3도에 도시된 바와 같이 실시예 1 내지 실시예 4까지 즉 PVC 혼합물이 TPU 혼합물보다 상대적으로 배합량이 많다하더라도 인열강도의 변화는 거의 없었으나 실시예 5 즉, TPU 혼합물 40%와 PVC 혼합물 60%인 경우부터 TPU 혼합물량이 점차 증가함에 따라 인열강도도 계속 증가하는 것으로 나타났다.That is, as shown in FIG. 1 and FIG. 2, the tensile strength and elongation increase gradually as the amount of TPU mixture blended into the PVC mixture increases, and the tear strength is shown in FIG. From 1 to 4, i.e., even though the PVC mixture had a larger amount of blend than the TPU mixture, there was little change in tear strength, but from Example 5, that is, 40% of the TPU mixture and 60% of the PVC mixture, the amount of TPU mixture gradually increased. As it increased, the tear strength continued to increase.
그리고, 100% 탄성계수의 변화는 제4도에 도시된 바와 같이 TPU 혼합물의 양이 증가됨에 따라 점차 감소하다가 실시예 7 즉, TPU 혼합물 60중량%와 PVC 혼합물 40중량%인 경우부터 TPU 혼합물량이 증가하더라도 100% 탄성계수 변화는 거의 없다.In addition, the change in the 100% modulus of elasticity decreases gradually as the amount of the TPU mixture is increased as shown in FIG. Even with this increase, there is little change in the 100% modulus of elasticity.
이에 따라 본 발명에서 PVC에 TPU를 배합함으로써 종래 PVC의 물성을 개선하기 위해 배합하여 사용하였던 ABS, NBR, NBS수지 보다 개선의 효과가 크다. 즉 기존 ABS, NBR수지는 인장강도, 신장율과 같은 특정 물성만을 증가시키나 TPU의 경우에는 기계적 강도는 물론 PVC 연질품의 내한성 및 내마모성도 동시에 증가시키므로 ABS, NBR, NBS 경우보다 PVC 개질제로서 적합한 것으로 판명되었다. 또한 TPU의 캘린더 가공시 TPU의 특성상 강철재료에 점착되는 현상으로 인해 작업이 불가능하여 특정의 활제를 사용하나 PVC가 첨가됨으로해서 캘린더 가공이 용이해지게 된다.Accordingly, by blending the TPU to PVC in the present invention, the effect of improvement is greater than that of ABS, NBR, and NBS resins, which are conventionally used to improve the physical properties of PVC. In other words, the existing ABS and NBR resins only increase specific properties such as tensile strength and elongation, but in the case of TPU, they also increase the mechanical strength as well as the cold resistance and wear resistance of PVC soft products. . In addition, due to the phenomenon of sticking to the steel material due to the characteristics of the TPU during the calendering of the TPU, it is impossible to work with it, but a specific lubricant is used, but the calendering becomes easy because PVC is added.
한편 상기 설명에서와 같은 물성 변화를 나타내는 본 발명 수지조성물의 각 실시예에 따른 실제 조작사진을 제5a도 내지 f도에 도시하였다.On the other hand, the actual operation photograph according to each embodiment of the resin composition of the present invention showing the physical property change as described above is shown in Figs. 5a to f.
즉, 제5a도 내지 f도는 도트매핑(Dot Mapping) 방식을 이용하여 촬영한 것인바, 이는 본 발명에 따라 제조된 수지조성물의 PVC 수지중 염소(Cl)를 윈도우(Window)로 설정하여 도트매핑을 실시한 뒤 SEM(Scanning Electro Microscope) 사진 촬영한 것으로, 사진상에 흰점으로 나타난 것이 염소로서 전체 조직내에 균일하게 분포된 것을 알 수 있다.That is, FIGS. 5A to 5F are photographed using a dot mapping method, which sets the chlorine (Cl) in the PVC resin of the resin composition prepared according to the present invention as a window (dot). After scanning, SEM (Scanning Electro Microscope) photographs were taken. It can be seen that the white spots on the photograph were uniformly distributed in the entire tissue as chlorine.
즉 제5a도는 실시예 1, 즉 PVC만으로 이루어진 수지의 SEM사진으로서 염소가 전체 조직내에 조밀하게 분포된 것을 도시하고 있고, 제5b도는 실시예 3, 즉 TPU 20중량%와 PVC 80중량%의 혼합물에 대한 SEM사진으로서 제5a도 보다는 염소의 분포 밀도가 작은 것을 도시하고 있으며, 제5c도는 실시예 5, 즉 TPU 40중량%와 PVC 60중량%의 혼합물에 대한 SEM사진인바, 사진중에서 검게 직선상으로 비스듬히 나타난 부위는 충분한 혼합이 이루어지지 않은 것을 나타내고 있다.That is, Figure 5a shows an example in which the chlorine is densely distributed in the entire structure as an SEM photograph of a resin composed only of PVC, and Figure 5b shows a mixture of 20% by weight of TPU and 80% by weight of PVC. SEM image of the chlorine distribution density is smaller than that of Figure 5a, Figure 5c is a SEM photograph of Example 5, that is, a mixture of 40% by weight of TPU and 60% by weight of PVC, black straight in the picture The part shown obliquely indicates that there is not enough mixing.
또한 제5d도는 실시예 7, 즉 TPU 60중량%와 PVC 40중량%의 혼합물에 대한 SEM사진으로서, 하부에 검게 나타난 부위는 충분한 혼합이 이루어지지 않은 것을 나타내고 있고, 제5e도는 실시예 9, 즉 TPU 80중량%와 PVC 40중량%의 혼합물에 대한 SEM사진으로서 염소의 분포밀도가 크게 감소됨을 도시하고 있으며, 제5f도는 실시예 10, 즉 TPU만으로 이루어진 수지의 SEM사진이다.In addition, Figure 5d is an SEM image of Example 7, that is, a mixture of 60% by weight of TPU and 40% by weight of PVC, the black portion at the bottom shows that there is not enough mixing, Figure 5e is Example 9, SEM image of the mixture of 80% by weight of TPU and 40% by weight of PVC shows that the distribution density of chlorine is greatly reduced, and FIG. 5f is an SEM image of the resin consisting of Example 10, that is, only TPU.
특히 실시예 1, 2의 결과를 각각 나타내는 제5a도 및 b도에 도시된 바와 같이 PVC 혼합물량이 TPU 혼합물량보다 상대적으로 많은 경우에 염소의 분포상태가 균일함을 쉽게 알 수 있다. 즉 제5a도 내지 f도에 도시된 바와 같이 본 발명은 TPU 혼합물과 PVC 혼합물이 균일하게 혼련시킨 수지조성물을 제조할 수 있도록 됨으로 해서 이들 TPU와 PVC의 혼합비율에 따른 각각의 수지조성물의 제조과정을 표준화하여 다양한 물성을 갖는 수지를 제조할 수 있을 뿐만 아니라 현재 PVC 착색용으로 사용되는 안료를 그대로 사용하여 TPU도 착색시킬 수 있게 된다.In particular, as shown in FIGS. 5a and b, which show the results of Examples 1 and 2, respectively, it can be easily seen that the distribution state of chlorine is uniform when the amount of PVC mixture is larger than the amount of TPU mixture. That is, as shown in FIGS. 5A to 5F, the present invention enables to prepare a resin composition in which the TPU mixture and the PVC mixture are uniformly kneaded, thereby preparing the respective resin compositions according to the mixing ratio of these TPU and PVC. In addition to standardizing the resin having a variety of physical properties it can be used to color the TPU by using the pigments currently used for PVC coloring as it is.
이상의 설명에서와 같이 본 발명은, PVC 혼합물에 TPU 혼합물을 소정비율로 배합함으로써 PVC 자체의 내한성이라던가 내마모성, 기계적 강도등과 같은 물성을 개선함은 물론 이를 다양화하여 각각의 용도에 맞는 수지 조성물을 제조하기 위한 작업조건을 표준화할 수 있어 생산성을 향상시킬 수 있는 효과가 있다.As described above, the present invention, by blending the TPU mixture in a predetermined ratio in the PVC mixture, improves the physical properties such as the cold resistance, abrasion resistance, mechanical strength, etc. of the PVC itself, as well as diversify the resin composition for each purpose The working conditions for manufacturing can be standardized, thereby improving productivity.
