Therefore, the butylsilent composition exhibits complicated shapes such as a vehicle body frame And exhibits an excellent effect that it can be easily applied to a member.
이하에는, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.
개시된 점착성 및 작업성이 우수한 실란트 부틸 조성물은 이소부틸렌 이소프렌 공중합체, 폴리이소부텐, 에틸렌비닐아세테이트, 안정제, 점착부여제 및 충전제로 이루어지며, 이소부틸렌 이소프렌 공중합체 100 중량부, 폴리이소부텐 25 내지 52 중량부, 에틸렌비닐아세테이트 25 내지 52 중량부, 안정제 0.5 내지 3.5 중량부, 점착부여제 50 내지 110 중량부 및 충전제 300 내지 480 중량부로 이루어지는 것이 바람직하다.A cementitious butyl composition having excellent tackiness and workability, which is composed of an isobutylene isoprene copolymer, polyisobutene, ethylene vinyl acetate, a stabilizer, a tackifier and a filler, is characterized by comprising 100 parts by weight of an isobutylene isoprene copolymer, 25 to 52 parts by weight of ethylene vinyl acetate, 25 to 52 parts by weight of ethylene vinyl acetate, 0.5 to 3.5 parts by weight of a stabilizer, 50 to 110 parts by weight of a tackifier and 300 to 480 parts by weight of a filler.
상기 이소부틸렌 이소프렌 공중합체는 개시된 점착성 및 작업성이 우수한 실란트 조성물의 주재료가 되는 성분으로, 실란트 조성물에 수밀성, 기밀성 및 점착성을 부여하며 상온에서는 고상을 나타내는데, 이때, 고유의 물성인 점착력은 유지되기 때문에, 실란트 조성물을 부재를 점착시키는 역할을 한다.The isobutylene isoprene copolymer serves as a main component of the sealant composition having excellent tackiness and workability, and imparts watertightness, airtightness and adhesiveness to the sealant composition and exhibits a solid state at room temperature. At this time, , The sealant composition serves to adhere the member.
상기 폴리이소부텐은 25 내지 52 중량부가 함유되며, 상기 이소부틸렌 이소프렌 공중합체와 함께 점착성 및 작업성이 우수한 실란트 조성물의 주재료가 되는 성분으로, 실란트 조성물에 수밀성, 기밀성 및 점착성을 부여하며, 120 내지 140℃의 고온에서는 액상을 나타내기 때문에, 실란트 조성물이 상기의 온도범위에서 우수한 유동성 및 토출성을 나타내도록 하는 역할을 한다.The polyisobutene is contained in an amount of 25 to 52 parts by weight, and is used as a main ingredient of a sealant composition excellent in tackiness and workability together with the isobutylene isoprene copolymer. The sealant composition imparts watertightness, airtightness and adhesiveness to the sealant composition, And at 140 DEG C, the sealant composition plays a role of exhibiting excellent fluidity and dischargeability in the above temperature range.
상기 폴리이소부텐의 함량이 25 중량부 미만이면 실란트 조성물이 상기와 같은 고온에서 우수한 유동성 및 토출성을 나타낼 수 없으며, 상기 폴리이소부텐의 함량이 52 중량부를 초과하게 되면 제조비용이 지나치게 증가하여 바람직하지 못하다.If the content of the polyisobutene is less than 25 parts by weight, the sealant composition can not exhibit excellent flowability and dischargeability at the high temperatures as described above. If the content of the polyisobutene exceeds 52 parts by weight, the production cost is excessively increased I can not.
상기 에틸렌비닐아세테이트는 25 내지 52 중량부가 함유되며 우수한 점착성을 나타낼 뿐만 아니라 열가소성을 나타내기 때문에, 상기와 같은 고온에서 실란트 조성물의 토출성능을 향상시키는 역할을 한다.The ethylene vinyl acetate is contained in an amount of 25 to 52 parts by weight and exhibits excellent adhesiveness as well as thermoplasticity. Therefore, the ethylene vinyl acetate serves to improve the discharge performance of the sealant composition at such a high temperature.
상기 에틸렌비닐아세테이트의 함량이 25 중량부 미만이면 상기와 같은 고온에서 실란트 조성물의 토출성능이 저하될 수 있으며, 상기 에틸렌비닐아세테이트는 상온에서는 점착력이 저하되기 때문에 상기 에틸렌비닐아세테이트의 함량이 52 중량부를 초과하게 되면 실란트 조성물의 상온 점착력이 저하될 수 있다.If the content of ethylene vinyl acetate is less than 25 parts by weight, the discharge performance of the sealant composition may deteriorate at such a high temperature. Since the ethylene vinyl acetate has a low adhesive strength at room temperature, the ethylene vinyl acetate content is preferably 52 parts by weight The adhesive strength at room temperature of the sealant composition may be lowered.
상기 안정제는 0.5 내지 3.5 중량부가 함유되며, 테트라키스메틸렌-(3,5-디-터셔리-4-히드록시 하이드로시나메이트)메탄으로 이루어지는데, 실란트 조성물이 열이나 빛에 노출되었을 때, 물성이 저하되는 것을 억제하는 역할을 한다.The stabilizer is contained in an amount of 0.5 to 3.5 parts by weight and is composed of tetrakis methylene- (3,5-di-tertiary-4-hydroxyhydrocinnamate) methane. When the sealant composition is exposed to heat or light, And the like.
상기 안정제의 함량이 0.5 중량부 미만이면 상기와 같이 실란트 조성물이 열이나 빛에 노출되었을 때 물성의 저하를 억제하는 효과가 미미하며, 상기 안정제의 함량이 3.5 중량부를 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 제조비용을 증가시키게 된다.If the content of the stabilizer is less than 0.5 part by weight, the effect of suppressing the deterioration of physical properties when the sealant composition is exposed to heat or light is insufficient. If the content of the stabilizer exceeds 3.5 parts by weight, But the manufacturing cost is not improved.
상기 점착부여제는 50 내지 110 중량부가 함유되며, 석유수지 20 내지 45 중량부 및 폴리부텐 30 내지 65 중량부로 이루어지는데, 실란트 조성물에 점착성능을 향상시키는 역할을 한다.The tackifier comprises 50 to 110 parts by weight of petroleum resin, 20 to 45 parts by weight of petroleum resin, and 30 to 65 parts by weight of polybutene, which improves the adhesive performance of the sealant composition.
상기 석유수지는 상기 에틸렌비닐아세테이트와 같이 상온에서는 고상이지만, 고온에서는 액상으로 변하기 때문에, 실란트 조성물에 점착력뿐만 아니라, 고온 유동성, 토출성 및 형태안정성을 향상시키는 역할도 하는데, 상기 석유수지의 함량이 20 중량부 미만이면 실란트 조성물의 고온 유동성, 토출성 및 형태안정성을 향상시키는 효과가 미미하며, 상기 석유수지의 함량이 45 중량부를 초과하게 되면 상기의 효과들은 향상되나, 실란트 조성물의 침입도가 저하될 수 있다.Since the petroleum resin, like ethylene vinyl acetate, is solid at room temperature but changes into a liquid at high temperature, it plays a role not only in improving the adhesive strength, but also in improving the high temperature fluidity, dischargeability and form stability of the sealant composition. If the content of the petroleum resin is more than 45 parts by weight, the above effects are improved, but the penetration of the sealant composition is lowered. When the content of the petroleum resin is less than 20 parts by weight, the effect of improving the high temperature fluidity, dischargeability and form stability of the sealant composition is insignificant. .
이때, 상기 석유수지는 특별히 한정되지 않고, 120 내지 140℃의 고온에서 유동성 및 토출성이 우수하며, 실란트 조성물의 형태안정성을 향상시킬 수 있는 것이면 어떠한 것이든 사용가능하나, 일본 제온(주)의 Quinton A-100을 사용하는 것이 바람직하다.The petroleum resin is not particularly limited and any petroleum resin may be used as long as it has excellent flowability and dischargeability at a high temperature of 120 to 140 ° C and can improve the morphological stability of the sealant composition. Quinton A-100 is preferably used.
또한, 상기 폴리부텐은 실란트 조성물의 점착력을 향상시키는 역할을 하는데, 폴리이소부텐에 비해 점도가 매우 낮기 때문에 실란트 조성물의 유동성 및 토출성을 향상시키는 역할을 한다.In addition, the polybutene serves to improve the adhesion of the sealant composition, and has a lower viscosity than polyisobutene, thereby improving fluidity and dischargeability of the sealant composition.
상기 폴리부텐의 함량이 30 중량부 미만이면 실란트 조성물의 점착력이 저하될 수 있으며, 상기 폴리부텐의 함량이 65 중량부를 초과하게 되면 상온에서 실란트 조성물의 침입도가 지나치게 향상되며, 낮은 점도로 인해 실란트 조성물의 형태안정성이 저하될 수 있다.If the content of the polybutene is less than 30 parts by weight, the adhesive strength of the sealant composition may deteriorate. If the content of the polybutene exceeds 65 parts by weight, penetration of the sealant composition at room temperature is excessively improved, The morphological stability of the composition may be degraded.
상기 충전제는 300 내지 480 중량부가 함유되며, 카본블랙, 실리카, 탄산칼슘 및 탈크로 이루어진 그룹에서 선택된 하나 이상으로 이루어지며, 카본블랙 20 내지 45 중량부, 실리카 20 내지 45 중량부, 탄산칼슘 130 내지 195 중량부 및 탈크 130 내지 195 중량부로 이루어지는 것이 바람직하다.The filler is contained in an amount of 300 to 480 parts by weight, and is composed of at least one selected from the group consisting of carbon black, silica, calcium carbonate and talc, and comprises 20 to 45 parts by weight of carbon black, 20 to 45 parts by weight of silica, 195 parts by weight and 130-195 parts by weight of talc.
상기 카본블랙은 실란트 조성물이 변색되는 것을 방지하는 역할도 하지만, 120 내지 140℃의 고온에서 토출되는 제품이 일정 형태의 형태를 유지한 채로 토출될 수 있도록 하는 역할을 하며, 실란트 조성물이 토출 된 후에 상온으로 냉각된 후에는 일정한 형태를 유지할 수 있도록 형태안정성을 향상시키는 역할을 한다.The carbon black serves to prevent the discoloration of the sealant composition, but it serves to enable the product discharged at a high temperature of 120 to 140 ° C to be discharged while maintaining a certain shape, and after the sealant composition is discharged After cooling to room temperature, it plays a role of improving morphological stability so that it can maintain a certain shape.
상기 카본블랙의 함량이 20 중량부 미만이면 실란트 조성물의 응집력이 저하되어 결과적으로는 침입도가 지나치게 향상되며, 상기 카본블랙의 함량이 45 중량부를 초과하게 되면 침입도가 지나치게 낮아져 바람직하지 못하다.If the content of the carbon black is less than 20 parts by weight, the cohesive force of the sealant composition is lowered, resulting in an excessively improved penetration. If the content of the carbon black exceeds 45 parts by weight, penetration becomes too low.
또한, 상기 실리카는 상기 카본블랙과 유사한 역할을 하면서 카본블랙의 물성을 보완하는 역할을 하는데, 상기 실리카의 함량이 20 중량부 미만이면 실란트 조성물의 응집력이 저하되어 결과적으로는 침입도가 지나치게 향상되며, 상기 실리카의 함량이 45 중량부를 초과하게 되면 침입도가 지나치게 낮아져 바람직하지 못하다.When the content of the silica is less than 20 parts by weight, the cohesive force of the sealant composition is lowered, resulting in an excessively improved penetration. As a result, If the content of the silica exceeds 45 parts by weight, penetration becomes too low, which is undesirable.
또한, 상기 탄산칼슘은 실란트 조성물이 고온에서 우수한 토출성능을 나타낼 수 있도록 하며, 다른 충전제 성분들에 비해 원료가격이 낮기 때문에 제품의 제조비용을 낮춰주는 역할을 하는데, 상기 탄산칼슘의 함량이 130 중량부 미만이면 상기의 효과가 미미하며, 상기 탄산칼슘의 함량이 195 중량부를 초과하게 되면 실란트 조성물의 고온 유동성, 토출성 및 점착력이 저하된다.The calcium carbonate serves to lower the manufacturing cost of the product because the silane composition can exhibit excellent discharge performance at a high temperature and the raw material cost is lower than other filler components. When the content of the calcium carbonate is 130 weight The above effect is insignificant. If the content of the calcium carbonate exceeds 195 parts by weight, the high temperature fluidity, dischargeability and adhesion of the sealant composition are lowered.
또한, 상기 탈크는 상기 탄산칼슘과 마찬가지로 실란트 조성물의 제조비용을 낮춰줄 뿐만 아니라, 실란트 조성물이 고온에서 도출된 후에 일정한 형태를 유지할 수 있도록 형태안정성을 향상시키는 역할을 하는데, 상기 탈크의 함량이 130 중량부 미만이면 상기의 효과가 미미하며, 상기 탈크의 함량이 130 중량부를 초과하게 되면 실란트 조성물의 고온 유동성, 토출성 및 점착력이 저하된다.In addition, the talc not only lowers the production cost of the sealant composition like the calcium carbonate but also improves the morphological stability of the sealant composition so that the sealant composition can maintain a certain shape after being taken out at a high temperature. When the content of the talc is 130 If the amount of the talc is less than 130 parts by weight, the high temperature fluidity, dischargeability, and adhesion of the sealant composition may deteriorate.
상기의 성분으로 이루어지는 점착성 및 작업성이 우수한 실란트 조성물은 이소부틸렌 이소프렌 공중합체 100 중량부, 폴리이소부텐 25 내지 52 중량부, 에틸렌비닐아세테이트 25 내지 52 중량부, 안정제 0.5 내지 3.5 중량부, 점착부여제 50 내지 110 중량부 및 충전제 300 내지 480 중량부를 교반기에 투입하고 150 내지 250rpm의 속도로 교반하면서 10 내지 20분 동안 교반하여 제조되는데, 상기의 과정을 통해 제조된 실란트 조성물은 가열장치가 구비된 토출장치에 투입된 후에 120 내지 140℃의 온도로 가열하여 액상으로 용융되면 토출장치에 구비된 노즐을 통해 부재에 적용된다.The sealant composition excellent in tackiness and workability comprising the above components is obtained by mixing 100 parts by weight of an isobutylene isoprene copolymer, 25 to 52 parts by weight of polyisobutene, 25 to 52 parts by weight of ethylene vinyl acetate, 0.5 to 3.5 parts by weight of a stabilizer, 50 to 110 parts by weight of the filler and 300 to 480 parts by weight of the filler are put into a stirrer and stirred for 10 to 20 minutes at a speed of 150 to 250 rpm while the sealant composition prepared by the above- And is melted in a liquid state by heating at a temperature of 120 to 140 DEG C, and is applied to the member through a nozzle provided in the discharging device.
일 예로, 상기의 실란트 조성물을 차량의 바닥 차체 프레임과 연료펌프커버의 접촉부위 등에 적용하는 경우에는 연료펌프커버에 토출장치에 구비된 노즐을 통해 고온으로 가열되어 액상을 나타내는 실란트 조성물을 토출시킨 후에 상온으로 냉각시키면 연료펌프커버에 대해 우수한 점착강도를 나타낼 뿐만 아니라, 차량의 바닥 차체 프레임과 연료펌프커버 사이에 수밀성 및 기밀성을 유지시키는 실란트 q부재가 형성된다.For example, when the above-mentioned sealant composition is applied to a bottom body frame of a vehicle and a contact portion of a fuel pump cover, the fuel pump cover is heated to a high temperature through a nozzle provided in a discharge device to discharge a sealant composition Cooling to room temperature not only exhibits excellent adhesive strength to the fuel pump cover, but also forms a sealant q member between the bottom vehicle body frame of the vehicle and the fuel pump cover to maintain watertightness and airtightness.
따라서, 개시된 점착성 및 작업성이 우수한 부틸 실란트 조성물은 수밀성, 기밀성, 점착성 및 형태안정성이 우수할 뿐만 아니라, 고온에서 우수한 유동성 및 토출성을 나타내기 때문에 종래에 사용되는 노즐을 통해서도 차량의 바닥 차체 프레임과 같은 복잡한 형상을 나타내는 부재에 간편하게 시공되는 효과를 나타낸다.Therefore, since the butyl sealant composition having excellent tackiness and workability is excellent in watertightness, airtightness, tackiness, and shape stability, and exhibits excellent flowability and dischargeability at high temperatures, And the like can be easily installed on a member having a complicated shape.
