Description
본 발명은 PBO섬유의 UV저항성 향상을 위한 표면처리방법에 관한 것으로서 UV에 의한 강도저하를 감소시켜 응용 분야를 넓히기 위한 표면처리방법이다.The present invention relates to a surface treatment method for improving the UV resistance of PBO fibers, and is a surface treatment method for widening the application field by reducing the decrease in the strength by UV.
우주항공, 자동차, 선박 등의 산업의 발달에 따라 섬유소재 분야에서도 유연하면서 고강도, 고내열성을 가지는 고기능성섬유에 대한 관심이 증대되고 있다. 그 중에서도 1998년 처음으로 일본의 Toyobo사에서 Zylonⓡ이라는 상표명으로 출시한 poly(p-phenylene benzobisoxazole)(PBO) 섬유는 상업화된 모든 합성섬유 중에서 최고의 인장 강도와 탄성률을 발휘하는 것으로 잘 알려져 있다. PBO 섬유는 대표적인 헤테로고리 방향족 고분자 (Heterocyclic Aromatic Polymer)로 이루어진 섬유로서 강도가 파라계 아라미드 섬유의 약 2배에 이르며, 탄소섬유와 비슷한 탄성율과 약 650℃의 높은 분해 온도와 LOI가 65인 난연성을 가지고 있을 뿐만 아니라 가볍고 유연한 섬유의 특성 또한 겸비하고 있어 차세대 수퍼섬유라고 불리고 있다.With the development of industries such as aerospace, automobiles, and ships, there is growing interest in high-functional fibers having flexibility and high strength and high heat resistance in the field of textile materials. Among them, poly (p-phenylene benzobisoxazole) (PBO) fiber, which was first marketed by Toyobo in Japan under the trade name Zylon ⓡ , is known to exhibit the highest tensile strength and elastic modulus among all commercialized synthetic fibers. PBO fiber is a typical heterocyclic aromatic polymer. Its strength is about twice that of para-aramid fibers. It has a modulus of elasticity similar to that of carbon fiber, a high decomposition temperature of about 650 ° C, and a flame retardancy of LOI of 65 In addition to having it, it also combines the characteristics of light and flexible fibers and is called the next generation super fiber.
이러한 PBO 섬유는 우주항공, 군용 및 산업용 분야에서 고성능 복합재료의 보강섬유로서 큰 잠재력을 가지고 있다. 그러나 우수한 강도와 내열성, 내화학성 등의 특성에도 불구하고 PBO 섬유는 압축강도가 인장강도에 비해 매우 낮은 단점을 가지고 있으며, 더욱이 경쟁 재료인 파라계 아라미드 섬유, 초고분자량폴리에틸렌 섬유나 폴리아릴레이트 섬유에 비해 보다 낮은 UV 안정성을 가지는 치명적 단점이 응용 분야에 제약을 가져올 수가 있다. 그 동안 PBO 섬유의 표면에너지를 증대시켜 복합재료에서 수지와의 젖음성(wettability)을 향상시키는 표면처리에 대해서는 많은 연구가 있었으나, UV 조사하에서 PBO 섬유의 기계적 특성이 크게 저하되는 메카니즘에 대한 연구와 UV 저항성을 향상시키기 위한 표면처리기술 개발은 그리 많지 않았다. UV 노출 전 약 33 g/d의 강도를 가지고 있는 Zylonⓡ 섬유를 UV에 약 24시간 노출시켰을 때 노출 전에 비해 강도가 약 55% 감소하여 산업용 파라계 아라미드 섬유 보다 낮은 약 15 g/d의 강도를 가진다고 보고되고 있으며, 수산화기를 가지는 dihydroxy poly(p-phenylene benzobisoxazole) 공중합체를 통하여 UV저항성을 향상시키는 연구결과도 발표되고 있다. These PBO fibers have great potential as reinforcing fibers for high performance composites in aerospace, military and industrial applications. However, in spite of its excellent strength, heat resistance and chemical resistance, the PBO fiber has a disadvantage in that the compressive strength is very low compared to the tensile strength. Further, the PBO fiber has a disadvantage in that it can not be used in the competitive aramid fiber, ultra high molecular weight polyethylene fiber or polyarylate fiber The fatal disadvantage of having a lower UV stability than the conventional one can impose limitations on the application field. There have been many researches on the surface treatment which improves the wettability with the resin in the composite material by increasing the surface energy of the PBO fiber. However, the mechanism of the degradation of the mechanical properties of the PBO fiber under UV irradiation and the UV There have been few developments in surface treatment technology to improve resistance. Zylon ⓡ fibers with a strength of about 33 g / d before exposure to UV for about 24 hours were exposed to UV for about 24 hours, which resulted in a reduction in strength of about 55% compared to before exposure and a strength of about 15 g / d lower than industrial para- aramid fibers , And studies have been made to improve the UV resistance through hydroxylated dihydroxy poly (p-phenylene benzobisoxazole) copolymer.
상기 PBO섬유와 다른 합성섬유에는 UV저항성을 증가시키는 특허로서 대한민국특허출원 제10-2007-0140499호에서는 벤조트리아졸계 자외선흡수제, 페놀릭계 및/또는 포스파이트계 산화안정제 및 힌더드 아민계 광안정제를 소정 범위의 량으로 각각 폴리에틸렌테레프탈레이트 베이스 수지에 혼합하되, 그 총량을 제어하여 용융방사함으로서, 자외선에 대한 내광성이 양호하면서도 강도가 거의 저하되지 않는 폴리에틸렌테레프탈레이트의 용융방사방법을 제시하고 있으나, 본 발명의 대상인 PBO섬유에 대해서는 그 방법을 제시하지는 못하고 있다.In Korean Patent Application No. 10-2007-0140499, as a patent for increasing the UV resistance to PBO fibers and other synthetic fibers, benzotriazole-based ultraviolet absorbers, phenolic and / or phosphite-based oxidative stabilizers and hindered amine light stabilizers There is proposed a melt spinning method of polyethylene terephthalate in which the light resistance of the polyethylene terephthalate is good while the light resistance against ultraviolet light is good and the strength is hardly lowered by mixing the polyethylene terephthalate base resin with the polyethylene terephthalate base resin in a predetermined amount, The method of PBO fiber, which is the object of the invention, can not be proposed.
그러므로 본 발명에 의하면, PBO섬유의 단점인 낮은 UV 안정성을 보완하여 우주항공, 군용 및 산업용 분야에서 고성능 복합재료의 보강섬유로서 큰 잠재력이 있는 PBO 섬유의 응용 분야를 확대하기 위하여 효과적인 표면처리방법을 제공하는 것을 기술적과제로 한다.Therefore, according to the present invention, an effective surface treatment method is applied to expand the application field of PBO fiber having a great potential as a reinforcing fiber of high performance composite material in the aerospace, military, and industrial fields by supplementing low UV stability which is a disadvantage of PBO fiber The technical problem is to provide.
그러므로 본 발명에 의하면, 수분산폴리우레탄, UV흡수제, HALS(Hindered Amine Light Stabilizer)계 광안정제 및 잔부로서 물로 이루어지는 처리액에 PBO(poly(p-phenylene benzobisoxazole))섬유를 픽업율 40~50%로 디핑한 후 100~120℃, 30~50분간 열처리하는 것을 특징으로 하는 PBO섬유의 UV저항성 향상을 위한 표면처리방법이 제공된다.
Therefore, according to the present invention, PBO (poly (p-phenylene benzobisoxazole)) fibers are picked up at a pick-up rate of 40 to 50% to water-dispersed polyurethane, UV absorbent, Hindered Amine Light Stabilizer (HALS) light stabilizer, , Followed by heat treatment at 100 to 120 ° C for 30 to 50 minutes. A surface treatment method for improving the UV resistance of the PBO fiber is provided.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 폴리p-페닐렌벤조비족사졸(poly(p-phenylene benzobisoxazole, 이하 "PBO"섬유라 한다.)섬유의 UV저항성 향상을 위한 표면처리방법은 수분산폴리우레탄, UV흡수제, HALS(Hindered Amine Light Stabilizer)계 광안정제 및 잔부로서 물로 이루어지는 처리액에 PBO(poly(p-phenylene benzobisoxazole))섬유를 디핑한 후 열처리하여 이루어진다.The surface treatment method for improving the UV resistance of the poly (p-phenylene benzobisoxazole) (hereinafter referred to as "PBO" fiber) of the present invention is a water-dispersed polyurethane, UV absorbent, HALS Amine Light Stabilizer PBO (poly (p-phenylene benzobisoxazole)) fiber is dipped in a treatment liquid containing a light stabilizer and water as the remainder, followed by heat treatment.
PBO섬유는 고성능 복합재료의 보강섬유로서 우수한 강도와 내열성, 내화학성 등의 특성에도 불구하고 낮은 UV 안정성을 가지는 단점을 보완하여 응용 분야를 넓히기 위해 본 발명의 UV저항성 향상을 위한 표면처리방법을 행한다.The PBO fiber is a reinforcing fiber of a high performance composite material, and despite the characteristics such as excellent strength, heat resistance, and chemical resistance, the surface treatment method for enhancing the UV resistance of the present invention is carried out in order to broaden the application field to compensate for the disadvantage of low UV stability .
우선, 수분산폴리우레탄, UV흡수제, HALS(Hindered Amine Light Stabilizer)계 광안정제 및 잔부로서 물로 이루어지는 처리액을 준비한 후 PBO(poly(p-phenylene benzobisoxazole))섬유를 픽업율 40~50%로 디핑한 후 100~120℃, 30~50분간 열처리하게 된다.First, PBO (poly (p-phenylene benzobisoxazole)) fibers were dipped in a pick-up rate of 40 to 50% after preparing a water-dispersed polyurethane, UV absorbent, HALS (Hindered Amine Light Stabilizer) light stabilizer, Followed by heat treatment at 100 to 120 ° C for 30 to 50 minutes.
상기 처리액은 수분산폴리우레탄 5~10 중량%, UV흡수제 0.5~5중량%, HALS(Hindered Amine Light Stabilizer)계 광안정제 0.5~5중량% 및 잔부로서 물로 이루어지는 것이 바람직한데, 수분산폴리우레탄은 섬유의 촉감에 영향을 미치지 않고, UV흡수제, HALS(Hindered Amine Light Stabilizer)계 광안정제와의 상용성이 우수하므로 바람직하다. 수분산폴리우레탄은 5~10 중량%이 되도록 하는 것이 5중량%미만에서는 PBO 섬유와의 접착력이 저하되어 내구성이 불량하며, 10중량%를 초과하는 경우에는 분산성은 양호하나 수분산 폴리우레탄의 과다 도포에 의한 촉감이 저하되는 문제점이 발생한다. 특히 상기 수분산폴리우레탄은 비이온계 계면활성제를 수지대비 0.1~1.0중량% 포함하도록 하는 것이 UV흡수제 및 안정제의 분산성에 도움을 준다.The treatment liquid is preferably composed of 5 to 10% by weight of an aqueous dispersion polyurethane, 0.5 to 5% by weight of an UV absorbent, 0.5 to 5% by weight of a HALS (Hindered Amine Light Stabilizer) light stabilizer, and water as the remainder, Is preferable because it is excellent in compatibility with a UV absorber and a Hindered Amine Light Stabilizer (HALS) light stabilizer without affecting tactile feel of the fiber. When the amount of the water-dispersed polyurethane is less than 5% by weight, the adhesive strength with the PBO fiber is lowered and the durability is poor. When the amount of the water-dispersed polyurethane is more than 10% by weight, There arises a problem that the tactile sensation due to application is deteriorated. Particularly, the water-dispersed polyurethane contains 0.1 to 1.0 wt% of a nonionic surfactant relative to the resin, which contributes to the dispersibility of the UV absorbent and the stabilizer.
상기 UV흡수제는 자외선을 흡수하여 고분자의 분해를 초래하는 자유라디칼의 형성을 억제하는 역할을 하며, 황변 등 색상변화에 주로 관여한다. 본 발명에서 UV흡수제는 벤조트리아졸형(Benzo-triazoles type)은 2-[2-하이드록시-3,5-디-(1,1-디메틸벤질)]-2H-벤조트리아졸(2-[2-hydroxy-3,5-di-(1,1-dimethylbenzyl)]-2H- Benzotriazole(C30H29N3O)) 또는 2,2'-메틸렌비스(6-(2H-벤조트리아졸-2-일)-4-,1,1,3,3,테트라메틸부틸)페놀)(2,2'-Methylene bis(6-(2H-benzotriazol-2- yl)-4-,1,1,3,3,tetramethylbutyl)phenol)(C41H50N6O2))을 사용할 수 있고, 벤조페논형(Benzo-phenones type)은 2,4-디하이트록시 벤조페논(2,4-Dihytroxy Benzophenone(C13H100))을, 트리아진형(Triazine type)은 2-[4,6-비스(2,4-디메틸페닐)-1,3,5-트리아진-2-일]-5-(이소옥틸록시)페놀 (2-[4,6-bis(2,4-dimethylphenyl) -1,3,5-triazin-2-yl]-5-(isooctyloxy)phenol)(C33H39N3O2)를 사용할 수 있다. The UV absorber plays a role in suppressing the formation of free radicals which absorbs ultraviolet rays and causes decomposition of the polymer, and is mainly involved in the change of hue and other color. In the present invention, the UV absorber is preferably a benzo-triazoles type compound selected from the group consisting of 2- [2-hydroxy-3,5-di- (1,1-dimethylbenzyl)] -2H-benzotriazole -hydroxy-3,5-di- (1,1- dimethylbenzyl)] - 2H- benzotriazole (C 3 0H 2 9N 3 O)) or 2,2'-methylenebis (6- (2H- benzotriazol--2 (2,2'-methylene bis (6- (2H-benzotriazol-2-yl) -4-, 1,1,3 , 3, tetramethylbutyl) phenol (C 41 H 5 0N 6 O 2 ), and the benzo-phenones type can be 2,4-dihydroxybenzophenone (2,4-dihydroxybenzophenone C 13 H 100)) to, yttria started (triazine type) is 2- [4,6-bis (2,4-dimethylphenyl) -1,3,5-triazin-2-yl] -5- (isopropyl hydroxy-octyl) phenol (2- [4,6-bis (2,4 -dimethylphenyl) -1,3,5-triazin-2-yl] -5- (isooctyloxy) phenol) (C 33 H 39 N 3 O 2 ) Can be used.
HALS(Hindered Amine Light Stabilizer)계 광안정제는 이미 형성된 자유라디칼을 다시 원상의 안정한 상태로 돌아가게 해 주는 역할을 하며, 광택, 강도, 신율 등 물성변화에 주로 관여한다. 본 발명에서 광안정제는 2,2,6,6-tetramethyl piperidine의 유도체인 hindered amine light stabilizers(Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidinyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidinyl)imino]])가 사용된다. HALS는 구조에 아민(amine)이 포함되어 있으며, 태양광선에 의한 플라스틱 소재나 비닐제품의 노화, 변색을 방지해주는 역할을 하고 전자제품이나 통신장비 케이스 등 플라스틱을 이용한 각종제품에 사용된다. 이들은 자외선을 직접 흡수하지는 않지만 라디칼 Scavenger로 작용한다. 라디칼 Scavenger는 자외선으로부터 광분해되어 생성된 자유라디칼을 소멸시킴으로써 연쇄적인 광산화 반응을 정지시키는 역할을 한다. UV흡수제와 HALS계 광안정제는 특히 2 : 1의 비율로 혼합하는 것이 바람직하다.Hindered Amine Light Stabilizer (HALS) light stabilizer acts to restore the free radicals that have already been formed to the original stable state, and is mainly involved in changes in physical properties such as gloss, strength and elongation. In the present invention, the light stabilizer is a derivative of 2,2,6,6-tetramethyl piperidine, hindered amine light stabilizers (Poly [[6 - [(1,1,3,3-tetramethylbutyl) amino] triazine-2,4-diyl] [(2,2,6,6-tetramethyl-4-piperidinyl) imino] -1,6-hexanediyl [(2,2,6,6-tetramethyl- ]) Is used. HALS contains amines in its structure and prevents aging and discoloration of plastic materials and vinyl products by sunlight, and is used in various products using plastic such as electronic products and communication equipment cases. They do not absorb ultraviolet light directly but act as a radical Scavenger. Radical Scavenger is responsible for stopping the photooxidation reaction by destroying free radicals generated by photolysis from ultraviolet rays. The UV absorber and the HALS light stabilizer are preferably mixed in a ratio of 2: 1 in particular.
이렇게 준비된 처리액에 PBO(poly(p-phenylene benzobisoxazole))섬유를 픽업율 40~50%로 디핑한 후 100~120℃, 30~50분간 열처리하여 본 발명의 PBO섬유의 UV저항성 향상을 위한 표면처리를 완료하게 된다.PBO (poly (p-phenylene benzobisoxazole)) fibers were dipped in the prepared treatment solution at a pickup ratio of 40 to 50%, and then heat-treated at 100 to 120 ° C for 30 to 50 minutes to obtain a surface for improving the UV resistance of the PBO fiber of the present invention Processing is completed.
따라서 본 발명에 의하면, PBO섬유의 단점인 낮은 UV 안정성을 보완하여 우주항공, 군용 및 산업용 분야에서 고성능 복합재료의 보강섬유로서 큰 잠재력이 있는 PBO 섬유의 응용 분야를 확대하기 위하여 수분산폴리우레탄에 UV 흡수제와 안정제를 혼입 표면처리함으로써 UV에 의한 강도저하를 감소시킬수 있다.Therefore, according to the present invention, in order to expand the application field of PBO fiber having a great potential as a reinforcing fiber of a high performance composite material in the aerospace, military and industrial fields by supplementing low UV stability which is a disadvantage of PBO fiber, The UV-induced strength reduction can be reduced by incorporating a UV absorber and a stabilizer.
