Abstract
본 발명의 초산비닐에틸렌 수지와 스틸렌블록공중합체 수지를 포함하는 접착수지 조성물 및 이를 이용하여 제조한 접합-제진강판을 제공한다.
본 발명의 접착수지 조성물은 초산비닐에틸렌 수지와 스틸렌블록공중합체 수지의 함량을 최적화하여 유기용제를 이용한 점성도 조절 없이도 충분한 접착력을 발휘하므로 유기용제의 사용으로 인한 환경오염의 염려가 없는 장점이 있으며 스틸렌블록공중합체 수지의 사용으로 인해 제진손실계수가 향상되었으므로 내구성 및 제진성능이 모두 우수한 친환경 접합-제진강판을 제조 할 수 있는 장점이 있다.
또한 본 발명의 접착수지 조성물은 고형의 박막필름 형태로 제공되므로 두께, 폭 등의 규격 관리 편의성과 함께 접합-제진강판 제품의 연속적 생산을 용이하게 할 뿐 아니라 열융착형(핫멜트형, Hot Melt Type)의 접착소재에 의해 공정간 가열 접합 후 방냉 과정만으로 즉시 제품이 완성되므로 뛰어난 생산성을 제공하는 장점이 있다.An adhesive resin composition comprising vinyl ethylene acetate resin and a styrene block copolymer resin of the present invention and a bonded-vibration-dampening steel sheet manufactured using the same are provided.
The adhesive resin composition of the present invention optimizes the content of vinyl ethylene acetate resin and styrene block copolymer resin to demonstrate sufficient adhesive strength without adjusting viscosity using organic solvents, so there is no concern about environmental pollution due to the use of organic solvents, and there is no need to worry about environmental pollution due to the use of organic solvents. Since the vibration loss coefficient has been improved due to the use of block copolymer resin, there is an advantage in manufacturing eco-friendly bonded-vibration-isolation steel sheets with excellent durability and vibration isolation performance.
In addition, since the adhesive resin composition of the present invention is provided in the form of a solid thin film, it not only facilitates the continuous production of bonded and anti-vibration steel sheet products along with the convenience of managing specifications such as thickness and width, but also provides a heat-sealable (hot melt type) )'s adhesive material has the advantage of providing excellent productivity because the product is completed immediately with only a cooling process after heat bonding between processes.

In order to meet the increasing demands of consumers along with the development of industry, the demand for low prices for various industrial materials is increasing along with the concept of lightness, thinness, and smallness. At the same time, the need to develop materials that take into account complex functionality to ensure product convenience is emerging, and various demands, including functionality, durability, and price competitiveness, are emerging in industrial consumer goods.
전기자동차의 경우 주행효율을 증대시키기 위해 배터리를 비롯한 관련 장치 및 부품류의 경량화가 요구된다. 이에 따라 제조비용, 중량, 및 가공의 문제점이 있는 단일 층의 금속 판재를 대체할 수 있는 박막 금속판재 접합형 강판에 대한 기술개발 수요가 증가하고 있는 실정이며 부가 기능으로서 우수한 제진성능을 가진 접합 제진강판의 개발에 대한 필요성이 대두되고 있다. In the case of electric vehicles, weight reduction of batteries and related devices and parts is required to increase driving efficiency. Accordingly, there is an increasing demand for technology development for thin-film metal sheet bonded steel sheets that can replace single-layer metal sheets that have problems with manufacturing cost, weight, and processing. As an additional function, bonded vibration damping with excellent vibration damping performance is increasing. The need for development of steel plates is emerging.
통상적으로 제진강판(vibration damping steel)의 제조에 사용되는 접착 소재들은 제진 성능에 대한 고려 없이 금속 판재 사이의 접착력만을 가지는 경향이 있었으며 일부 제진(vibration control) 성능을 고려한 접착 소재라 할지라도 다양한 환경 조건에서 충분한 제진 성능을 발휘하지 못하는 문제점이 있었다. Typically, adhesive materials used in the manufacture of vibration damping steel tended to have only adhesive strength between metal plates without considering vibration damping performance, and even for adhesive materials that took some vibration control performance into account, they were used in various environmental conditions. There was a problem in that sufficient vibration suppression performance was not achieved.
한국등록특허 10-0861448에는 표면판재와 그 표면판재를 지지하는 지지판재를 소정의 점성도를 가져 흡음성과 제진성이 우수한 접착 수지로 사용하므로 제진성, 흡음성 및 가공성을 향상시킨 접합강판이 개시되어 있다. 그러나 상기 특허에 사용된 접착수지는 에틸 아세테이트 44 내지 46 중량%, 비닐 아세테이트/아크릴 코폴리머 40 내지 42 중량%, 이소프로필 알코올 8 내지 10 중량%, 톨루엔 1 내지 3 중량%, 비닐 아세테이트 3중량% 이하, 아세트알데히드 0.1 중량% 이하로 구성되었으며 상기 유기용제를 9 내지 13중량% 사용하는 방법으로 접착수지의 점성도를 제어하였다. 상기 접합강판의 판재에 도포된 후 건조과정을 통해 상기 유기용제가 휘발되어 사라지게 되는데 이때 휘발된 유기용제가 공기 중으로 배출되면 작업자의 건강에 악영향을 미치게 되므로 이를 포집하여 제거하기 위한 고가의 정화시설이 요구되는 실정이며 건조로 인해 다량의 유기용제가 사라진 부위에 기포가 형성되거나 접착수지층의 두께가 비정상적으로 감소하는 등 품질관리에 어려움이 있었다. Korean Patent No. 10-0861448 discloses a laminated steel sheet with improved vibration damping properties, sound absorbing properties, and processability by using an adhesive resin with a predetermined viscosity and excellent sound absorption and vibration damping properties for the surface plate and the support plate supporting the surface plate. . However, the adhesive resin used in the above patent is 44 to 46% by weight of ethyl acetate, 40 to 42% by weight of vinyl acetate/acrylic copolymer, 8 to 10% by weight of isopropyl alcohol, 1 to 3% by weight of toluene, and 3% by weight of vinyl acetate. Hereinafter, it consisted of 0.1% by weight or less of acetaldehyde, and the viscosity of the adhesive resin was controlled by using 9 to 13% by weight of the organic solvent. After being applied to the plate of the bonded steel plate, the organic solvent volatilizes and disappears through the drying process. At this time, if the volatilized organic solvent is discharged into the air, it has a negative impact on the health of workers, so an expensive purification facility is required to collect and remove it. This was a necessary situation, and there were difficulties in quality control, such as bubbles forming in areas where a large amount of organic solvent disappeared due to drying, or the thickness of the adhesive resin layer abnormally decreasing.
또한 유기용제를 통해 향상된 접착수지의 잔존 점성으로 인해 프래스 성형, 절곡, 절단 등의 가공 공정시 가해지는 기계적 압력에 의해 두께가 변형되는 문제가 발생할 우려가 있을 뿐 아니라 고온에 장기간 노출되는 경우 접착소재의 열유동 현상에 의해 규격 안정성과 시공 정밀도가 저하되는 문제점이 있었다. In addition, due to the residual viscosity of the adhesive resin improved through organic solvents, there is a risk of thickness deformation due to mechanical pressure applied during processing processes such as press forming, bending, and cutting, and when exposed to high temperatures for a long period of time, the adhesive may be damaged. There was a problem in that the standard stability and construction precision were deteriorated due to the heat flow phenomenon of the material.

본 발명의 접착수지층은 고분자 재료의 점탄성 특성을 충분히 이용하여 유연성 영역과 강직성 영역을 부정형적으로 배치하므로 진동 발생원에서 전달되는 물리적인 운동에너지가 신속히 감소되는 고기능성의 제진소재 조성을 확보하고 이를 기존 접착제 기술에 접목시켜 뛰어난 제진성능의 접합-제진강판의 제조를 용이하게 하는 접착소재의 구성을 확보하였다. 상세하게는 본 발명의 접착수지층은 주된 접착수지 성분인 초산비닐에틸렌 수지에 스틸렌블록공중합체 수지가 도입됨으로서 상기 초산비닐에틸렌 수지에 의해 형성된 고무상의 조직(Rubber Matrix) 및 강직성 조직(Hard Domain)에 스틸렌블록공중합체 수지가 형성하는 유연성 구간(Flexible Segment) 및 강직성 구간(Stiff Segment)이 부정형적으로 혼재된 분자구조를 가지게 된다. 따라서 상기 접착수지층은 외부 진동에너지가 상기 유연성 구간을 거쳐 강직성 구간에 도달하여 열에너지로 변환됨으로써 진동 감쇄 효과가 향상되는 것이다.The adhesive resin layer of the present invention makes full use of the viscoelastic properties of polymer materials to irregularly arrange the flexible and rigid regions, thereby securing the composition of a highly functional vibration isolating material in which the physical kinetic energy transmitted from the vibration source is quickly reduced. By applying adhesive technology, we have secured the composition of an adhesive material that facilitates the manufacture of bonded and vibration-isolating steel sheets with excellent vibration-isolating performance. In detail, the adhesive resin layer of the present invention is a styrene block copolymer resin introduced into vinyl ethylene acetate resin, which is the main adhesive resin component, so that the rubber matrix and hard domain formed by the vinyl ethylene acetate resin are formed. The styrene block copolymer resin has a molecular structure in which flexible segments and stiff segments are irregularly mixed. Therefore, the adhesive resin layer improves the vibration damping effect by converting external vibration energy into heat energy through the flexible section and reaching the rigid section.

The Styrene Block Co-Polymer resin is a styrene-Ethylene-Propylene-Styrene Co-Polymer resin and a styrene-isoprene-styrene copolymer (Styrene-Isoprene-Styrene).

상기 제조한 접합-알루미늄 제진강판, 접합-냉간압연강판 제진강판 또는 접합-스테인레스 스틸 제진강판에 대하여 박리접착하중시험(시험기준 KS F4737: 박리접착하중시험) 및 제진성(진동감쇠특성) 평가시험(시험기준 KS D0076: 중앙지지 정상여진법)을 수행하였다.Peel adhesion load test (Test standard KS F4737: Peel adhesion load test) and vibration damping (vibration damping characteristics) evaluation test on the laminated aluminum damping steel sheet, laminated cold rolled steel sheet, or laminated stainless steel damping steel sheet manufactured above. (Test standard KS D0076: Center-supported normal excitation method) was performed.
하기 표 2는 본 발명의 박리접착하중시험 및 제진성 평가결과를 보여준다.Table 2 below shows the peel adhesion load test and vibration damping evaluation results of the present invention.
수지조성물로서 초산비닐에틸렌 수지만을 사용하고 활제와 열안정제를 첨가하여 제조한 접착수지 조성물(비교예)로 접합-제진강판을 제조한 후 접착성능 및 제진성능을 평가하였다. 평가 결과 판재의 종류에 상관없이 높은 수준의 접착강도(알루미늄 판재: 173N/25㎜, 냉간압연강판 판재: 151N/25㎜ 또는 스테인레스 스틸 판재: 127N/25㎜)를 보이는 것으로 확인되었다. A bonded-vibration-dampening steel plate was manufactured using an adhesive resin composition (comparative example) prepared by using only vinyl ethylene acetate resin as a resin composition and adding a lubricant and a heat stabilizer, and then the adhesive performance and vibration-dampening performance were evaluated. As a result of the evaluation, it was confirmed that a high level of adhesive strength was observed regardless of the type of plate (aluminum plate: 173N/25mm, cold rolled steel plate: 151N/25mm, or stainless steel plate: 127N/25mm).
상기 초산비닐에틸렌 수지의 함량을 49.5중량% 수준까지 낮추고 나머지 수지를 점탄성(Visco-Elasticity) 수지인 폴리에틸렌 수지, 스틸렌블록공중합체1 수지 또는 스틸렌블록중합체2 수지로 대체하여 제조한 접착수지 조성물(실시예 1, 2 및 7)로 접합-제진강판을 제조한 후 접착성능 및 제진성능을 평가하였다.Adhesive resin composition prepared by reducing the content of the vinyl ethylene acetate resin to 49.5% by weight and replacing the remaining resin with visco-elasticity resin, such as polyethylene resin, styrene block copolymer 1 resin, or styrene block polymer 2 resin (implementation) After manufacturing the bonded-vibration-dampening steel sheets in Examples 1, 2, and 7), the adhesive performance and vibration-dampening performance were evaluated.
평가 결과 초산비닐에틸렌 수지와 폴리에틸렌 수지를 사용한 실시예 1의 경우 초산비닐에틸렌 수지를 100% 사용한 비교예에 대비하여 접착강도가 29 내지 34% 감소하고 제진손실계수가 13 내지 15% 감소하여 접착성능과 제진성능이 모두 감소하는 것으로 확인되었다. As a result of the evaluation, in Example 1 using vinyl ethylene acetate resin and polyethylene resin, compared to the comparative example using 100% vinyl ethylene acetate resin, the adhesive strength was reduced by 29 to 34% and the vibration loss coefficient was reduced by 13 to 15%, thereby improving the adhesive performance. It was confirmed that both the and vibration control performance decreased.
이에 대비하여 초산비닐에틸렌 수지와 스틸렌블록공중합체1 수지를 사용한 실시예 2의 경우 비교예 대비 접착강도가 23 내지 29% 감소하였으나 실시예 1과 유사한 수준의 접착성능 감소를 보이는 반면 제진손실계수가 26 내지 45% 증가하여 제진성능이 향상된 것으로 확인되었으며; 초산비닐에틸렌 수지와 스틸렌블록공중합체2 수지를 사용한 실시예 7의 경우 실시예 2와 유사하게 접착성능은 감소(접착강도: 13 내지 32% 감소)되는 반면 제진성능은 향상(제진손실계수: 24 내지 29% 증가)되는 것으로 확인되었다.In contrast, in Example 2 using vinyl ethylene acetate resin and styrene block copolymer 1 resin, the adhesive strength decreased by 23 to 29% compared to the comparative example, but the adhesive performance decreased to a similar level as Example 1, while the vibration loss coefficient was It was confirmed that the vibration control performance was improved by 26 to 45%; In the case of Example 7 using vinyl ethylene acetate resin and styrene block copolymer 2 resin, similar to Example 2, the adhesive performance was reduced (adhesive strength: 13 to 32% reduced), while the vibration damping performance was improved (vibration loss coefficient: 24 to 29% increase).
상기 실시예 2 및 7을 바탕으로 점탄성(Visco-Elasticity) 수지인 스틸렌블록공중합체1 수지와 스틸렌블록중합체2 수지의 함량을 변화시켜 접합-제진강판을 제조한 후 접착성능과 제진성능을 비교분석하였다. Based on Examples 2 and 7 above, bonded-vibration-isolating steel sheets were manufactured by changing the contents of styrene block copolymer 1 resin and styrene block polymer 2 resin, which are visco-elasticity resins, and then comparative analysis of adhesive performance and vibration isolation performance. did.
초산비닐에틸렌 수지를 대체하는 스틸렌블록공중합체1 수지의 함량을 25중량%(실시예 3), 15중량%(실시예 4), 10중량%(실시예 5) 또는 5중량%(실시예 6)으로 변화시켜 접착수지 조성물을 제조한 후 이를 이용하여 제진강판을 제조한 후 접착성능 및 제진성능을 평가한 결과 스틸렌블록공중합체1 수지의 함량이 증가함에 따라 접착성능은 감소하고 제진성능은 향상되는 것으로 확인되었다. 특히 초산비닐에틸렌 수지와 스틸렌블록공중합체1 수지를 94.5% 및 5%의 함량으로 혼합하여 제조한 실시예 6의 경우 모든 판재에서 접착강도가 초산비닐에틸렌 수지만을 사용하여 제조한 비교예의 접착성능과 유사한 수준을 보이고 제진성능 또한 비교예 대비 53% 내지 77% 증가한 것으로 확인되어 가장 우수한 성능을 보이는 것으로 확인되었다. The content of styrene block copolymer 1 resin, which replaces vinyl ethylene acetate resin, was 25% by weight (Example 3), 15% by weight (Example 4), 10% by weight (Example 5), or 5% by weight (Example 6). ), manufactured an adhesive resin composition, manufactured a vibration-isolating steel plate using it, and evaluated the adhesive and vibration-isolating performance. As the content of styrene block copolymer 1 resin increased, the adhesive performance decreased and the vibration-isolating performance improved. It was confirmed that this was the case. In particular, in the case of Example 6, which was manufactured by mixing vinyl ethylene acetate resin and styrene block copolymer 1 resin at a content of 94.5% and 5%, the adhesive strength on all plates was compared to the adhesive performance of the comparative example manufactured using only vinyl ethylene acetate resin. It showed a similar level to that of and the vibration control performance was also confirmed to have increased by 53% to 77% compared to the comparative example, showing the best performance.
초산비닐에틸렌 수지를 대체하는 스틸렌블록공중합체2 수지의 함량을 25중량%(실시예 8), 15중량%(실시예 9), 10중량%(실시예 10) 또는 5중량%(실시예 11)으로 변화시켜 접착수지 조성물을 제조한 후 이를 이용하여 제진강판을 제조한 후 접착성능 및 제진성능을 평가한 결과 스틸렌블록공중합체2 수지의 함량이 증가함에 따라 접착성능은 감소하고 제진성능은 향상되는 것으로 확인되었다. 특히 초산비닐에틸렌과 스틸렌블록공중합체2 수지를 94.5% 및 5%의 함량으로 혼합하여 제조한 실시예 11의 경우 모든 판재에서 접착강도가 초산비닐에틸렌만을 사용하여 제조한 비교예의 접착성능과 유사한 수준을 보이고 제진성능 또한 비교예 대비 77% 내지 107% 증가한 것으로 확인되어 가장 우수한 성능을 보이는 것으로 확인되었다. The content of styrene block copolymer 2 resin, which replaces vinyl ethylene acetate resin, was 25% by weight (Example 8), 15% by weight (Example 9), 10% by weight (Example 10), or 5% by weight (Example 11). ) to produce an adhesive resin composition and then use it to manufacture a vibration-isolating steel plate. As a result of evaluating the adhesive and vibration-absorbing performance, as the content of styrene block copolymer 2 resin increases, the adhesive performance decreases and the vibration-isolating performance improves. It was confirmed that this was the case. In particular, in the case of Example 11, which was manufactured by mixing vinyl ethylene acetate and styrene block copolymer 2 resin at an amount of 94.5% and 5%, the adhesive strength on all plates was similar to that of the comparative example manufactured using only vinyl ethylene acetate. It was confirmed that the vibration control performance also increased by 77% to 107% compared to the comparative example, showing the best performance.
제진성능의 경우 초산비닐에틸렌 수지를 대체하는 스틸렌블록공중합체1(스티렌-에틸렌-스티렌 공중합체) 수지 또는 스틸렌블록공중합체2(스티렌-에틸렌-스티렌 공중합체) 수지의 함량이 50중량%(실시예 2 또는 7)인 경우 초산비닐에틸렌 수지를 대체하는 스틸렌블록공중합체1(스티렌-에틸렌-스티렌 공중합체) 수지 또는 스틸렌블록공중합체2(스티렌-에틸렌-스티렌 공중합체) 수지의 함량이 50중량%보다 낮은 경우보다 낮은 제진손실계수를 가지는 것으로 확인되었는데 이는 초산비닐에틸렌 수지와 스틸렌블록공중합체 수지 사이의 분산성이 높지 않아 접착성능 및 제진성능의 향상 정도가 제한적이었기 때문으로 판단된다. 정리하면 초산비닐에틸렌 수지에 대비한 스틸렌블록공중합체의 함량이 50%이상으로 과다 할 경우, 폴리머 블랜딩(혼합) 과정에서 분산성이 좋지 않을 뿐 아니라 접합-제진강판 제조시 금속판재 사이의 접착력이 저하되어 제진성 향상 성능이 지속적으로 증가하지는 않고 저조하게 되는 경향이 있다.In the case of vibration damping performance, the content of styrene block copolymer 1 (styrene-ethylene-styrene copolymer) resin or styrene block copolymer 2 (styrene-ethylene-styrene copolymer) resin, which replaces vinyl ethylene acetate resin, is 50% by weight (in practice) In case of example 2 or 7), the content of styrene block copolymer 1 (styrene-ethylene-styrene copolymer) resin or styrene block copolymer 2 (styrene-ethylene-styrene copolymer) resin replacing vinyl ethylene acetate resin is 50 weight. It was confirmed that the vibration control loss coefficient was lower than in the case of lower than %. This is believed to be because the dispersibility between vinyl ethylene acetate resin and styrene block copolymer resin was not high, so the degree of improvement in adhesive performance and vibration control performance was limited. In summary, if the content of styrene block copolymer compared to vinyl ethylene acetate resin is excessive (more than 50%), not only is the dispersibility poor during the polymer blending process, but also the adhesion between metal sheets is reduced when manufacturing bonded and damped steel sheets. As a result, the vibration damping performance tends to become low rather than continuously increasing.
현재 유통되는 접합-제진강판의 경우 종래의 액상형 또는 페이스트형 접착제를 사용하는 경우 접착강도 60N/25㎜ 수준이며 제진성능 향상을 위해 고가의 수지를 사용하는 경우 접착강도 80 내지 125N/25㎜ 수준이다. 또한 초산비닐에틸렌 수지를 사용하여 제진성능을 향상시킨 종래의 제품은 제진손실계수가 평균 2% 수준이며 고가의 일본산 제품의 경우 2.5% 수준이다.In the case of currently distributed bonded-vibration-isolating steel sheets, when conventional liquid or paste-type adhesives are used, the adhesive strength is at the level of 60 N/25 mm, and when expensive resin is used to improve vibration isolation performance, the adhesive strength is at the level of 80 to 125 N/25 mm. . In addition, conventional products with improved vibration suppression performance using vinyl ethylene acetate resin have an average vibration suppression loss coefficient of about 2%, and for expensive Japanese products, it is about 2.5%.
이에 대비하여 본 발명의 접합-제진강판은 접합수지용 조성물에 있어서 종래의 초산비닐에틸렌 수지를 스틸렌블록공중합체1 수지 또는 스틸렌블록공중합체2 수지로 5% 내지 50%수준으로 대체하는 것만으로도 제진성능이 향상된 접합-제진강판을 제조할 수 있는 것으로 판단된다. In contrast to this, the bonded-vibration damping steel plate of the present invention can be made by simply replacing the conventional vinyl ethylene acetate resin with styrene block copolymer 1 resin or styrene block copolymer 2 resin at the level of 5% to 50% in the bonding resin composition. It is believed that it is possible to manufacture bonded-vibration-dampening steel plates with improved vibration-dampening performance.
상세하게는 접착성능의 저하가 없어 내구성이 뛰어나면서도 제진성능이 향상된 접합-제진강판을 제조하는 경우 초산비닐에틸렌 수지를 스틸렌블록공중합체1(스티렌-에틸렌-스티렌 공중합체) 수지 또는 스틸렌블록공중합체2(스티렌-에틸렌-스티렌 공중합체) 수지로 5% 대체하는 것이 바람직하며 이 경우 초산비닐에틸렌 수지만을 사용한 접합-제진강판과 유사한 접착강도를 가지면서도 제진성능이 53 내지 107% 증가한 접합-제진강판을 제조할 수 있는 것으로 판단된다.Specifically, when manufacturing a bonded-vibration-isolating steel sheet with excellent durability and improved vibration-isolation performance due to no decrease in adhesive performance, vinyl ethylene acetate resin is replaced with styrene block copolymer 1 (styrene-ethylene-styrene copolymer) resin or styrene block copolymer. It is preferable to replace 5% with 2 (styrene-ethylene-styrene copolymer) resin. In this case, the bonded-vibration damping steel sheet has an adhesive strength similar to that of a bonded-vibration-dampening steel sheet using only vinyl ethylene acetate resin, while the vibration-dampening performance is increased by 53 to 107%. It is believed that it can manufacture steel plates.
또한 접착성능은 종래의 접합-제진강판의 수준을 유지하면서도 제진성능이 월등히 향상된 접합-제진강판을 제조하는 경우 초산비닐에틸렌 수지를 스틸렌블록공중합체1 수지 또는 스틸렌블록공중합체2 수지로 6 내지 25% 대체하는 것이 바람직하며 이 경우 초산비닐에틸렌 수지만을 사용한 접합-제진강판과 유사한 접착강도(108N/25㎜ 이상)를 가지면서도 제진성능이 53 내지 230% 증가한 접합-제진강판을 제조할 수 있는 것으로 판단된다.In addition, when manufacturing a bonded-vibration-dampening steel sheet with significantly improved vibration-dampening performance while maintaining the level of adhesion performance of a conventional bonded-vibration-dampening steel sheet, vinyl ethylene acetate resin is used as styrene block copolymer 1 resin or styrene block copolymer 2 resin at a ratio of 6 to 25%. % replacement is desirable, and in this case, it is possible to manufacture a bonded-vibration-isolating steel sheet with a 53 to 230% increase in vibration-isolating performance while having a similar adhesive strength (108 N/25 mm or more) to a bonded-vibration-isolating steel sheet using only vinyl ethylene acetate resin. It is judged that
이 경우 초산비닐에틸렌 수지에 대한 스틸렌블록공중합체1 수지 또는 스틸렌블록공중합체2 수지의 대체 정도가 증가할 수 록 접착성능은 저하되고 제진성능은 향상된다는 점을 고려하여 적절한 배합을 선택하는 것이 바람직한 것으로 판단된다.In this case, it is desirable to select an appropriate mix considering that as the degree of substitution of styrene block copolymer 1 resin or styrene block copolymer 2 resin for vinyl ethylene acetate resin increases, the adhesive performance decreases and the vibration damping performance improves. It is judged that
실시예 12에서는 본 발명의 초산비닐에틸렌 수지, 스틸렌블록공중합체1 수지 및 스틸렌블록공중합체2 수지를 모두 포함하는 접착수지 조성물을 제조하고 이를 이용하여 접합-제진강판을 제조한 후 접착성능과 제진성능을 평가하였다. 평가결과 초산비닐에틸렌 수지와 스틸렌블록공중합체1 수지로 구성된 접합수지 조성물 또는 초산비닐에틸렌 수지와 스틸렌블록공중합체2 수지로 구성된 접합수지 조성물로 제조한 제진강판에 대비하여 접착성능이 낮으며 제진성능의 향상 정도도 스틸렌블록공중합체1 수지 또는 스틸렌블록공중합체2 수지가 초산비닐에틸렌 수지를 10중량% 수준으로 대체한 실시예(실시예 5 및 10) 보다 낮은 제진성능을 보이는 것으로 확인되었다. 그러나 초산비닐에틸렌 수지, 스틸렌블록공중합체1 수지 및 스틸렌블록공중합체2 수지를 모두 포함하는 접착수지 조성물로 제조된 접합-제진강판도 유통되는 종래의 접합-제진강판의 성능을 만족하므로 제품화가 가능할 것으로 판단된다.In Example 12, an adhesive resin composition containing all of the vinyl ethylene acetate resin, styrene block copolymer 1 resin, and styrene block copolymer 2 resin of the present invention was prepared, and a bonded-vibration damping steel plate was manufactured using the same, and then the adhesive performance and vibration damping were tested. Performance was evaluated. As a result of the evaluation, the adhesive performance is low and the vibration isolation performance is low compared to the vibration isolation steel plate manufactured with a bonding resin composition composed of vinyl ethylene acetate resin and styrene block copolymer 1 resin or a bonding resin composition composed of vinyl ethylene acetate resin and styrene block copolymer 2 resin. It was confirmed that the degree of improvement was lower than that of the examples (Examples 5 and 10) in which styrene block copolymer 1 resin or styrene block copolymer 2 resin replaced vinyl ethylene acetate resin at 10% by weight. However, bonded-vibration-isolating steel sheets manufactured with an adhesive resin composition containing all of vinyl ethylene acetate resin, styrene block copolymer 1 resin, and styrene block copolymer 2 resin can also be commercialized because they satisfy the performance of conventional bonded-vibration-isolating steel sheets in circulation. It is judged that
정리하면 본 발명의 접합-제진강판은 초산비닐에틸렌의 일부를 점탄성(Visco-Elasticity) 수지인 스틸렌블록공중합체1(스티렌-에틸렌-스티렌 공중합체) 또는 스틸렌블록중합체2(스티렌-이소프렌-스티렌 공중합체)로 대체한 것으로 수지를 혼합하기 위한 유기용제가 전혀 사용되지 않으므로 유기용제의 휘발로 인한 문제점이 해결되었을 뿐 아니라 우수한 접착강도를 유지하면서도 비약적으로 향상된 제진성능을 가지는 장점이 있다.In summary, the bonded-vibration damping steel sheet of the present invention is a visco-elasticity resin made of a portion of vinyl ethylene acetate, such as Styrene Block Copolymer 1 (Styrene-Ethylene-Styrene Copolymer) or Styrene Block Polymer 2 (Styrene-Isoprene-Styrene Copolymer). Since no organic solvent is used to mix the resin, the problem caused by volatilization of the organic solvent is not only solved, but it also has the advantage of dramatically improved vibration control performance while maintaining excellent adhesive strength.
본 발명의 접합수지 조성물은 초산비닐에틸렌 및 스틸렌블록공중합체를 포함하므로 가공성이 용이하고 우수한 접착성능 및 제진성능을 발휘하는 장점이 있다. 본 발명의 스틸렌블록공중합체는 열가소성수지로서 고유의 유연성을 가져 별도의 용제 또는 가소제 등의 성분을 가하지 않더라도 제진강판의 생산과정에서 원료의 취급이 용이하고 접합 과정이 원활한 장점이 있으며 접합수지층에서 초산비닐에틸렌 수지와 상이한 강직성 조직(Hard Domain)을 통해 강성 구간(Stiff Segment)을 형성하므로 진동에너지에 저항하는 결정질 또는 유리질 영역의 역할을 수행하여 뛰어난 제진성능을 발휘하게 되는 것이다.Since the bonding resin composition of the present invention contains vinyl ethylene acetate and styrene block copolymer, it has the advantage of being easy to process and exhibiting excellent adhesive performance and vibration damping performance. The styrene block copolymer of the present invention is a thermoplastic resin and has inherent flexibility, so it has the advantage of easy handling of raw materials and smooth bonding process in the production process of anti-vibration steel sheets even without adding components such as separate solvents or plasticizers. Since it forms a stiff segment through a hard domain that is different from vinyl ethylene acetate resin, it plays the role of a crystalline or glassy region that resists vibration energy and exhibits excellent vibration damping performance.
본 발명의 상세한 실시예를 통해 스틸렌블록공중합체의 적용량(대체량)이 증가함에 따라서 제진성능은 비례하여 향상되지만 접착성능은 반비례하는 경향성을 확인하였으므로 제품에 요구되는 물성치와 경제성을 감안하여 실시예의 범위에서 선택적으로 적용하는 것이 효율적인 것으로 판단된다. Through detailed examples of the present invention, it was confirmed that as the application amount (replacement amount) of styrene block copolymer increases, the vibration damping performance improves proportionally, but the adhesive performance tends to be inversely proportional. Therefore, the scope of the examples is given in consideration of the physical properties required for the product and economic feasibility. It is judged to be efficient to apply it selectively.
