Description
본 발명은 우수한 내마모 특성을 갖는 폴리아미드 수지 조성물에 관한 것으로서, 더욱 상세하게는 폴리아미드 수지에 유리섬유, 초대분자량 폴리메틸실록산 (ultra-high molecular weight polydimethylsiloxane), 폴리테트라플루오르에틸렌(Polytetrafluoroethylene) 등을 함유시켜 열적성질과 기계적성질이 양호하며, 고속 고하중에서 우수한 내마모 특성을 갖는 유리섬유강화 폴리아미드 수지 조성물에 관한 것이다The present invention relates to a polyamide resin composition having excellent wear resistance, and more particularly, to a polyamide resin, such as glass fiber, ultra-high molecular weight polydimethylsiloxane, polytetrafluoroethylene, and the like. The present invention relates to a glass fiber-reinforced polyamide resin composition having good thermal and mechanical properties and excellent wear resistance at high speed and high loads.
회전체가 많은 산업업분야에서 저속, 저하중에서는 일반적인 마찰특성을 지닌 수지를 사용하여 사출성형품으로 사용할 수 있다. 그러나 베어링 케이지(BEARING CAGE)나 자동차 도아 체크 암(DOOR CHECK ARM) 등과 같은 부품에서는 고속의 회전과 고하중의 조건에서 많은 마찰에서도 열 발생이 낮고, 사출성형품의 마모가 적어 형상 유지성이 우수해야하는 유리섬유가 충진된 사출성형품들이 요구되고 있으며, 이는 일반 고분자나 자기윤활성이 우수하지 못한 고분자로서는 해 결이 불가능하다. In industrial fields where many rotors are used at low speeds and low loads, resins with general frictional properties can be used as injection molded products. However, parts such as bearing cages and door check arms, such as bearing cages, have low heat generation even under high friction under high-speed rotation and high load conditions. Fiber-filled injection molded products are required, which cannot be solved by general polymers or polymers with poor self-lubrication.
폴리아미드수지의 물성을 향상시키기 위해 첨가된 유리섬유는 고속의 회전과 고하중에서 마찰계수를 높게 하는 작용을 한다. 즉 내마모특성을 떨어지게 하여, 비마모량이 높아져 사출품의 형상을 유지시키지 못하여 장기간 사용할 때 사출성형품의 성능을 떨어뜨리게 한다.The glass fiber added to improve the physical properties of the polyamide resin serves to increase the coefficient of friction at high speed of rotation and high load. In other words, the wear resistance is lowered, the wear amount is increased, and the shape of the injection molded product is not maintained, and thus the performance of the injection molded product is degraded when used for a long time.
종래에 사출 성형품중 슬리이브나 기어제품 또는 마찰부품용으로 폴리아미드 수지나 아세탈 수지가 사용되어 왔으며 내마모성을 향상시키는 기술로서는 몰리브덴이나 실리콘 등을 함유시켜 자기 윤활성이 증가하도록하는 방법이 알려져 있다.Conventionally, polyamide resins and acetal resins have been used for sleeves, gear products or friction parts among injection molded articles. As a technique for improving abrasion resistance, a method of increasing molybdenum, silicon or the like to increase self-lubrication is known.
한국공개특허 1989-0019953호와 1990-0020162호에서는 폴리아마이드 수지에 이황화몰리브덴과 유리섬유를 첨가하는 방법이 있으나 이황화몰리브덴 사용시 각종 색상을 부여하는게 불가능하며 또한 본 발명에서 요구하는 사출성형품의 고속 고하중에서 낮은 동마찰계수와 비마모량, 즉 동마찰계수 0.01이하, 비마모량 10mg이하를 얻을 수 없다.In Korean Patent Publication Nos. 1989-0019953 and 1990-0020162, there is a method of adding molybdenum disulfide and glass fiber to polyamide resin, but it is impossible to impart various colors when using molybdenum disulfide, and also in the high speed and high load of the injection molded article required by the present invention. Low coefficient of kinetic friction and wear, ie less than 0.01 coefficient of kinetic friction, less than 10 mg of non-friction can not be obtained.
또한 미국특허 제5,700,863호 및 제5,726,232호에서는 폴리아미드수지에 내마모재 소재인 테프론을 사용하여 자기윤활성을 향상시키는 방법을 제안하고 있고, 미국특허 제4,898,905호에서는 폴리아미드수지에 내마모재 소재인 테프론, 이황화몰리브덴, 흑연을 사용하여 폴리아미드수지의 윤활성을 향상시키는 방법 즉 마찰계수를 낮추는 방법을 제안하고 있다. 그러나 이러한 선행기술의 경우에도 각종 색상을 부여하는게 불가능하며 또한 본 발명이 요구하는 유리섬유강화 폴리아미드수지의 고속, 고하중의 마찰조건에서 낮은 마찰계수나 비마모량을 얻을 수 없다.
In addition, U.S. Patent Nos. 5,700,863 and 5,726,232 propose a method of improving self-lubrication by using Teflon, a wear-resistant material for polyamide resin, and U.S. Patent No. 4,898,905 for a wear resistant material for polyamide resin Teflon, molybdenum disulfide, and graphite have been proposed to improve the lubricity of polyamide resin, that is, to lower the friction coefficient. However, even in the case of the prior art, it is impossible to impart various colors, and low friction coefficient or wear rate cannot be obtained under high speed and high load friction conditions of the glass fiber reinforced polyamide resin required by the present invention.
따라서 본 발명은 고속, 고하중의 마찰조건에서 기계적물성이 양호하고 형상유지성이 우수하며 또한 각종 색상을 부여하는 것이 용이한 유리섬유강화 폴리아미드 수지 조성물을 제공하는 것을 목적으로 한다. Accordingly, an object of the present invention is to provide a glass fiber-reinforced polyamide resin composition having good mechanical properties, excellent shape retention, and easy to impart various colors under friction conditions of high speed and high load.
상기한 과제를 해결하기 위한 본 발명자의 연구에서 상기한 목적에 부합하는 유리섬유강화 폴리아미드 수지는 동마찰계수가 0.01이하이고, 비마모량은 10mg 이하이어야 하며, 이러한 수지는 적정량의 초대분자량 폴리메틸실록산과 폴리테트라플루오르에틸렌를 배합하는 것에 의해 얻을 수 있다는 사실을 알게 되어 본 발명을 완성하게 된 것이다.
Glass fiber-reinforced polyamide resin meeting the above object in the study of the present inventors to solve the above problems should have a coefficient of kinetic friction of 0.01 or less, abrasion amount of less than 10mg, such a resin of an appropriate amount of high molecular weight polymethyl The present invention has been completed by knowing that it can be obtained by combining siloxane and polytetrafluoroethylene.
그러므로, 본 발명에 의하면 유리섬유강화 폴리아미드 수지 조성물에 있어서, 폴리아미드 수지 100중량부당 초대분자량 폴리메틸실록산 0.5 내지 5 중량부, 및 폴리테트라플루오르에틸렌 5 내지 15중량를 함유하는 것을 특징으로 하는 내마모성 유리섬유강화 폴리아미드수지 조성물이 제공된다. Therefore, according to the present invention, the glass fiber-reinforced polyamide resin composition contains 0.5 to 5 parts by weight of super molecular weight polymethylsiloxane and 5 to 15 parts by weight of polytetrafluoroethylene per 100 parts by weight of polyamide resin. A fiber reinforced polyamide resin composition is provided.
또한 본 발명에 의하면, 유리섬유강화 폴리아미드 수지 조성물에 있어서, 동마찰계수 0.01이하 및 비마모량 10mg 이하의 내마모특성을 만족하는 내마모성 유리섬유강화 폴리아미드 수지 조성물이 제공된다.According to the present invention, there is provided a wear-resistant glass fiber-reinforced polyamide resin composition which satisfies the wear resistance property of the dynamic friction coefficient of 0.01 or less and the specific wear amount of 10 mg or less.
이하, 본 발명을 보다 상세하게 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명에 따라 동마찰계수 0.01 이하와 비마모량은 10mg 이하를 동시에 만족하는 유리섬유강화 폴리아미드 수지 조성물은 고속회전과 고하중에서 사용되는 사출성형품에 대해 마찰에 의한 형상유지성과 기계적물성이 양호하고, 장기내열성이 우수하여 베어링 케이지, 자동차 도아 체크 암 등과 같은 부품에 적용하기에 매우 적합하다. According to the present invention, the glass fiber-reinforced polyamide resin composition satisfying the dynamic friction coefficient of 0.01 or less and 10 mg or less at the same time has good shape retention and mechanical properties due to friction with respect to injection molded articles used at high speed and high load. Its excellent long-term heat resistance makes it ideal for applications such as bearing cages and automotive door check arms.
바람직하게 상기한 특성을 만족하는 유리섬유강화 폴리아미드 수지 조성물은 폴리아미드 수지 100중량부당 초대분자량 폴리메틸실록산 0.5 내지 5 중량부 및 폴리테트라플루오르에틸렌 5 내지 15중량를 배합하는 것에 의해 제조할 수 있다. Preferably, the glass fiber-reinforced polyamide resin composition that satisfies the above properties can be prepared by blending 0.5 to 5 parts by weight of ultra-high molecular weight polymethylsiloxane and 5 to 15 parts by weight of polytetrafluoroethylene per 100 parts by weight of polyamide resin.
본 조성물에 있어서, 초대분자량 폴리메틸실록산과 불소수지는 유리섬유강화 폴리아미드 수지의 내마모특성 향상시킬 뿐만아니라 자기윤활성을 향상시키는 작용도 한다. In the present composition, the ultra-molecular weight polymethylsiloxane and the fluororesin not only improve the wear resistance of the glass fiber reinforced polyamide resin, but also improve the self-lubrication activity.
본 조성물에 함유되는 초대분자량 폴리메틸실록산은 성형후 성형물의 수지내 함유되어 있거나 표면에 피복된다. 초대분자량 폴리메틸실록산이 사출성형품과 상대재질인 금속과의 마찰시 표면에서 일차적으로 표면에 피복된 폴리메틸실록산이 윤활제 역활를 하고 시간이 경과함에 따라 수지 내부에 있는 폴리메틸실록산이 표면으로 이동하려는 성질이 있어 성형품의 손상을 억제하는 낮은 마찰계수와 비마모량을 갖게 한다. The ultra-molecular weight polymethylsiloxane contained in the present composition is contained in the resin of the molded product or coated on the surface after molding. When ultra-molecular weight polymethylsiloxane is rubbing between injection molded part and metal of relative material, polymethylsiloxane coated on the surface acts as a lubricant and polymethylsiloxane inside the resin is going to move to the surface as time passes. This results in a low coefficient of friction and abrasion resistance that prevents damage to the molded article.
기존의 저분자량의 액상 실리콘은 이축압출기에서 혼련시 쉽게 가스화되고 , 또한 사출성형품 제조시 성형품의 표면으로 이탈로 인한 성형품 표면의 불량의 원인이 되어 우수한 자기 윤활성을 유지할 수 없으며 수지내에 함유된 저분자량 액상 실리콘은 수지내에서 표면으로 이동하여는 성질이 강하여 장기간의 윤활성을 유지 못하는 단점이 있으나, 본 조성물에 함유되는 초대분자량 폴리메틸실록산은 그 자체가 내마모특성을 우수하게 하는 특성이 있다. Conventional low molecular weight liquid silicone is easily gasified when kneading in a twin screw extruder, and in the manufacture of injection molded products, it is a cause of defects on the surface of the molded product due to separation to the surface of the molded product. Liquid silicone has a disadvantage in that it is difficult to maintain long-term lubricity because of its property to move to the surface in the resin, the ultra-molecular weight polymethylsiloxane contained in the composition has the characteristics of excellent wear resistance itself.
본 발명에 따라 폴리아미드 수지 100중량부당 초대분자량 폴리메틸실록산을 0.5 내지 5 중량부를 함유하는 유리섬유강화 폴리아미드 수지는 이축압출기에서 가공시나 사출성형품내에서도 안정한 함량을 유지하고 우수한 자기윤활성을 나타낸다. 본 조성물중 초대분자량 폴리메틸실록산의 함량이 0.5중량부 미만이면 목적하는 낮은 마찰계수와 비마모량을 얻을 수가 없고, 또한 5 중량부 보다 많이 사용하는 경우에는 압출성형성의 저하로 사출성형품의 표면 불량을 초래할 수 있다. According to the present invention, the glass fiber reinforced polyamide resin containing 0.5 to 5 parts by weight of ultra-molecular weight polymethylsiloxane per 100 parts by weight of polyamide resin maintains a stable content even when processing in a twin screw extruder and exhibits excellent self-lubricating activity. If the content of ultra-molecular weight polymethylsiloxane in the present composition is less than 0.5 parts by weight, the desired low coefficient of friction and non-wearing amount cannot be obtained. Can cause.
이러한 초대분자량 폴리메틸실록산의 시중구입가능한 예로는 다우코닝사 제품인 MB50-011가 있다. A commercially available example of such ultra-molecular weight polymethylsiloxane is MB50-011 available from Dow Corning.
또한 본 조성물은 불소수지인 폴리테트라플루오르에틸렌을 함유하는데, 이러한 불소수지는 수지내에 첨가되어 사출성형한 제품의 표면에 막을 형성하여 상대재질인 금속과 마찰시 우수한 내마모특성을 지니게 한다. 그러나 내마모제로 사용되는 불소수지 단독으로 내마모 특성을 나타낼 시에는 많은 양의 첨가시에만 내마모특성을 발휘한다. 하지만 본 발명에서 목적하는 낮은 마찰계수와 비마모량이 낮은 특성을 지닌 유리섬유강화 폴리아미드 수지를 제조할 수 없게 된다.In addition, the composition contains polytetrafluoroethylene, which is a fluororesin, which is added to the resin to form a film on the surface of an injection molded product to have excellent abrasion resistance when rubbing with a metal, which is a relative material. However, when the fluorine resin used as an anti-wear agent alone exhibits anti-wear properties, it exhibits anti-wear properties only when a large amount is added. However, the glass fiber-reinforced polyamide resin having low frictional coefficient and low abrasion resistance desired in the present invention cannot be manufactured.
본 발명에 따라 초대분자량 폴리메틸실록산과 함께 폴리테트라플루오르에틸렌을 폴리아미드 수지 100중량부당 5 내지 15중량부의 양으로 함유시키게 되면 시너지효과를 발휘할 수 있게 된다. 본 조성물중 폴리테트라플루오르에틸렌의 함량 이 5중량부 미만이면 목적하는 낮은 마찰계수와 비마모량을 얻을 수가 없고, 15중량부를 초과하면 압출성형성의 저하와 제품의 원가를 상승시키는 문제점이 있다.According to the present invention, when the polytetrafluoroethylene is contained in an amount of 5 to 15 parts by weight per 100 parts by weight of the polyamide resin together with the ultra-molecular weight polymethylsiloxane, synergistic effects can be exerted. If the content of polytetrafluoroethylene in the present composition is less than 5 parts by weight, the desired low coefficient of friction and wear cannot be obtained. If the content is more than 15 parts by weight, there is a problem of lowering extrudability and increasing cost of the product.
본 조성물중 기본 베이스 폴리머인 폴리아미드 수지는 상대점도가 2.4∼3.5인 것이 바람직하다. 상대점도가 2.4 미만인 수지를 사용할 경우는 폴리아미드수지의 중합도가 어렵고, 상대점도 3.5이상인 경우에는 고점도인 관계로 흐름성이 낮아 사출성형이 어려운 문제점이 있다. 본 조성물에 특히 바람직한 폴리아미드 수지는 폴리아미드 66 또는 폴리아미드 6이다.It is preferable that the polyamide resin which is a basic base polymer in this composition is 2.4-3.5 relative viscosity. When the resin having a relative viscosity of less than 2.4 is used, the polymerization degree of the polyamide resin is difficult, and when the relative viscosity is 3.5 or more, the flowability is low due to the high viscosity, which makes injection molding difficult. Particularly preferred polyamide resins for this composition are polyamide 66 or polyamide 6.
본 조성물중 수지의 물성보강 목적으로 함유되는 유리섬유로는 폴리아미드 수지와 상용성을 갖도록 처리된 것이 바람직하다. 예를 들어, 폴리아미드의 말단기인 아민기와 화학적결합을 통하여 상용성이 있도록 유리섬유 표면에 실란이 처리된 것이 바람직하다. 특별히 제한하기 위한 것은 아니지만 본 조성물중 유리섬유 함량은 대략 폴리아미드 수지 100중량부당 30∼40중량부 정도가 적당하다.
The glass fiber contained for the purpose of reinforcing the physical properties of the resin in the composition is preferably treated to have compatibility with the polyamide resin. For example, the silane is preferably treated on the surface of the glass fiber so as to be compatible with the amine group, which is the end group of the polyamide, through chemical bonding. Although not particularly limited, the glass fiber content of the present composition is suitably about 30 to 40 parts by weight per 100 parts by weight of the polyamide resin.
