Description

무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 제조방법Manufacturing method of industrial textile product coated with plasticizer-free polypropylene modified compound composition
본 발명은 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 제조방법에 관한 것이다.The present invention relates to a method for producing an industrial textile product coated with a plasticizer-free polypropylene modified compound composition.
최근 유럽연맹이나 미국, 영연방국에서는 폴리염화비닐(PVC, Poly Vinyl Chloride) 사용에 대한 규제가 강화되고 있는 실정이며, 이에 따라 세계 각국은 폴리염화비닐을 대체하는 여러 가지 수지들의 개발을 시도하였으나, 가공성과 경제성면에서 폴리염화비닐에 견줄 수 있을 만한 수지는 개발되지 못했다.Recently, the EU, US, and Commonwealth countries have tightened regulations on the use of polyvinyl chloride (PVC). Accordingly, countries around the world have tried to develop various resins to replace polyvinyl chloride. In terms of processability and economy, no resin has been developed that can be compared with polyvinyl chloride.
폴리머 코팅 산업용 섬유제품은 일반적으로 폴리에스테르 직물에 폴리염화비닐 수지나 열가소성 폴리우레탄(Thermoplastic Polyurethane; TPU) 수지를 코팅하여 제조되고 있으나 폴리에스테르 직물에 폴리염화비닐 수지를 코팅하여 제조되는 산업용 섬유제품은 사용 후 폐기시킬 때 코팅 물질인 폴리염화비닐 수지와 폴리에스테르 직물의 분리가 힘들어 재활용 비용이 높아서 소각 폐기시키고 있는데 폐기 소각 시에 다이옥신 및 유독가스를 발생시키는 심각한 문제점이 있으며 또한 코팅 수지 가공 배합에 포함되는 프탈레이트 가소제로 인한 환경 호르몬 유해물질에 대한 규제가 강화되고 있는 실정이다.Polymer coating industrial textile products are generally manufactured by coating polyvinyl chloride resin or thermoplastic polyurethane (TPU) resin on a polyester fabric, but industrial textile products produced by coating polyvinyl chloride resin on a polyester fabric In case of disposal after use, it is difficult to separate the coating material of polyvinyl chloride resin and polyester fabric, so the recycling cost is high, and incineration is disposed of, but there is a serious problem of generating dioxin and toxic gas during incineration. Regulation of environmental hormone harmful substances due to the phthalate plasticizer is being tightened.
또한 폴리에스테르 직물에 TPU 수지를 코팅하여 제조되고 있는 산업용 섬유제품은 가공성에 있어서 폴리염화비닐에 사용되는 카렌다 공법이나 졸 코팅 공법의 적용이 불가능하고, 압출 T-Dies 공법에 의해서만 생산이 가능하여 생산 설비에 대한 제한성이 있고 코팅 물질인 TPU 수지가 고가라 경제성이 떨어지며, 이 또한 사용 후 폐기시킬 때 코팅물질인 TPU 수지와 폴리에스테르 직물의 분리가 힘들어 재활용 비용이 높아서 소각폐기 시키고 있는데 폐기 소각 시에 시안화수소 및 유독가스를 발생시키는 심각한 문제점이 있다. 또한 폴리에스테르 직물에 폴리염화비닐 수지나 TPU 수지를 코팅하여 제조되는 산업용 섬유제품은 접착제를 사용하여 라미네이션 과정을 거쳐야 하는 번거로움이 있다. In addition, industrial textile products manufactured by coating a TPU resin on a polyester fabric cannot be applied to the calender method or sol coating method used for polyvinyl chloride in processability, and can be produced only by the extrusion T-Dies method. The facility is limited and the TPU resin, which is a coating material, is expensive, and the economic efficiency is low.In addition, it is difficult to separate the TPU resin and polyester fabric, which is a coating material, when it is disposed of after use. There is a serious problem of generating hydrogen cyanide and toxic gases. In addition, industrial textile products produced by coating a polyvinyl chloride resin or TPU resin on the polyester fabric has a cumbersome lamination process using an adhesive.

상기 목적을 달성하기 위하여, 본 발명은 폴리프로필렌 직물 양면에 액상 타입의 수계 폴리올레핀 분산 수지를 1차로 코팅 또는 딥핑 처리하는 단계 및 상기 1차 코팅 또는 딥핑 처리한 폴리프로필렌 직물 양면에 폴리프로필렌 변성 컴파운드 조성물을 2차로 코팅하는 단계를 포함하며, 상기 폴리프로필렌 변성 컴파운드 조성물이 폴리프로필렌 수지 100 중량부에 대하여, 폴리프로필렌계 변성엘라스토머 20내지 150 중량부, 폴리스티렌계 변성엘라스토머 20 내지 100 중량부, 무기필러 0.1 내지 30 중량부, 산화방지제 0.1 내지 1.0 중량부, UV 흡수제 0.1 내지 2.0 중량부, 가공활제 0.1 내지 3.0 중량부 및 착색제 0.1 내지 15 중량부를 포함하여 이루어지는 것을 특징으로 하는 폴리프로필렌 변성 코팅 산업용 섬유제품의 제조방법을 제공한다.In order to achieve the above object, the present invention is a step of first coating or dipping the liquid-type water-based polyolefin dispersion resin on both sides of the polypropylene fabric and polypropylene modified compound composition on both sides of the primary coating or dipping treatment polypropylene fabric To the secondary coating step, wherein the polypropylene modified compound composition is based on 100 parts by weight of polypropylene resin, 20 to 150 parts by weight of polypropylene-based modified elastomer, 20 to 100 parts by weight of polystyrene-based modified elastomer, inorganic filler 0.1 To 30 parts by weight, 0.1 to 1.0 parts by weight of antioxidant, 0.1 to 2.0 parts by weight of UV absorber, 0.1 to 3.0 parts by weight of processing agent and 0.1 to 15 parts by weight of colorant of the polypropylene modified coating industrial textile product It provides a manufacturing method.
첫째, 본 발명은 폴리머 코팅 산업용 섬유제품의 제조 시 폴리프로필렌 변성 코팅 컴파운드 조성물을 이용하여 카렌더 공법과 압출 T-Dies 공법 모두 적용이 가능하여 가공성이 우수한 효과를 나타낸다.First, the present invention can be applied to both the calendering method and the extrusion T-Dies method using a polypropylene modified coating compound composition in the production of polymer coating industrial textiles, it shows an excellent processability.
둘째, 본 발명은 소각시 다이옥신 및 시안화수소 등의 유독가스를 발생시키지 않고, 접착을 위해 유기용제가 들어있지 않는 수계 폴리올레핀 분산 수지를 사용하기 때문에 휘발성유기화합물(V.O.C, Volatile Organic Compound)이 제조공정 상에서 발생하지 않아 대기오염에 무관하며, 심체로 사용하는 폴리프로필렌 직물과 코팅 물질이 동일계 물질이라 재활용이 100%로 가능하고, 인체에 유해한 환경호르몬 규제물질인 프탈레이트계 가소제를 전혀 사용하지 않아 무독성 친환경적인 효과를 나타낸다.Second, the present invention uses a water-based polyolefin dispersion resin that does not generate toxic gases such as dioxins and hydrogen cyanide when incinerated and does not contain an organic solvent for adhesion, so that a volatile organic compound (VOC) is produced in a manufacturing process. Since it does not occur in the air phase, it is irrelevant to air pollution, and the polypropylene fabric and coating material used as the core are the same material, and can be recycled with 100%, and it is non-toxic and eco-friendly because it does not use any phthalate-based plasticizer, which is a harmful substance to human body. Has an effective effect.
세째, 본 발명은 폴리에스테르 섬유에 폴리염화비닐을 코팅한 종래의 폴리염화비닐 산업용 섬유제품에 비해 내구성 및 내후성 면에서 우수한 물성을 나타낸다.Third, the present invention exhibits excellent physical properties in terms of durability and weather resistance compared to conventional polyvinyl chloride industrial textile products coated with polyvinyl chloride on polyester fibers.

이하, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되 이는 본 발명이 속하는 기술 분야에서 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, the preferred embodiments of the present invention and the physical properties of each component will be described in detail so that the present invention can be easily described in detail so that those skilled in the art can easily carry out the invention. It is not intended that the technical spirit and scope of the present invention be limited.
본 발명에 따른 심체로 사용되는 폴리프로필렌 직물은 용융 방사 방법으로 제조된 단사강도가 6.2 gf/d 내지 8.0 gf/d의 폴리프로필렌 모노필라멘트를 이용하여 텍스법 연계수(twist multiplier; TM) 6.7 내지 20의 합연사한 400 내지 1,500 데니아의 폴리프로필렌 멀티필라멘트사를 사용하여 경사 1인치 당 15 내지 40, 위사 1인치 당 15 내지 40의 제직 밀도를 지닌 평직 직물을 사용할 수 있다. The polypropylene fabric used as the core according to the present invention is a twisted multiplier (TM) using a polypropylene monofilament having a single yarn strength of 6.2 gf / d to 8.0 gf / d produced by the melt spinning method. Using 20 twisted yarns of 400-1,500 denia polypropylene multifilament yarns, it is possible to use plain weave fabrics having a weave density of 15 to 40 per inch of warp yarn and 15 to 40 per inch of weft yarn.
상기 폴리프로필렌 직물을 제직할 때 사용되는 폴리프로필렌 모노필라멘트의 단사 강도가 6.2 gf/d 미만이면 본 발명에서 구현하고자 하는 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 인장강도 및 인열강도가 낮아져서 상품가치가 떨어지며, 8.0 gf/d를 초과하면 범용으로 생산되지 않는 문제가 야기될 수 있다. Tensile strength and tearing strength of an industrial textile product coated with a plasticizer-free polypropylene modified compound composition to be implemented in the present invention when the single yarn strength of the polypropylene monofilament used when weaving the polypropylene fabric is less than 6.2 gf / d. Lowers the commodity value, and if it exceeds 8.0 gf / d may cause a problem that is not produced universally.
상기 폴리프로필렌 직물을 제직할 때 사용되는 폴리프로필렌 멀티필라멘트사는 반드시 TM 20이하의 합연사를 사용하여야 하며, 이는 1차로 코팅되는 수계 폴리올레핀 분산 수지가 섬유 사이로 일부 용융 침투되어야 직물과 컴파운드 조성물 사이의 층간 접착력이 우수해 지지만 무연사인 경우는 수계 폴리올레핀 분산 수지나 폴리프로필렌 변성 컴파운드 조성물의 용융 침투가 잘 되지 않아 본 발명에서 구현하고자 하는 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 접착력이 저하될 수 있다. 연사 정도는 TM이 20 이하가 바람직한데 20을 초과하면 제직한 직물의 표면 굴곡이 2차로 코팅하는 폴리프로필렌 변성 컴파운드 수지의 코팅량을 높여야하는 문제점이 있다. The polypropylene multifilament yarn used when weaving the polypropylene fabric must use a twisted yarn of TM 20 or less, which must be partially melt penetrated into the fiber between the water-based polyolefin dispersion resin first coated and the interlayer between the fabric and the compound composition. The adhesive strength is excellent, but in the case of non-twisted yarn, poor penetration of the water-based polyolefin dispersion resin or polypropylene modified compound composition may reduce the adhesive force of the industrial textile product coated with the plasticizer-free polypropylene modified compound composition to be implemented in the present invention. Can be. The degree of twisting is preferably 20 or less TM, but if it exceeds 20, the surface curvature of the woven fabric has a problem in that the coating amount of the polypropylene modified compound resin to be coated second.
상기 폴리프로필렌 직물을 제직할 때 사용되는 폴리프로필렌 멀티필라멘트사는 섬도가 400 내지 1,500 데니아인 것을 사용해야 하는데, 이때 400 데니아 미만인 경우에는 섬도가 낮기 때문에 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 인장강도 및 인열강도가 낮아서 폴리머 코팅 산업용 섬유제품에 사용하기에는 부적합하며, 1,500 데니아를 초과하면 직물의 표면 평활도가 떨어져서 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 외관이 나빠진다. 특히, 폴리머 코팅 산업용 섬유제품에 사용되는 것은 1,000 데니아의 멀티필라멘트사를 많이 사용하며 이것은 표준 제품으로 물성적인 측면이나 가격이 저렴하여 경제적이다.Polypropylene multifilament yarn used when weaving the polypropylene fabric should be used with a fineness of 400 to 1,500 denia, when the fineness is less than 400 denier of the industrial fiber products coated with a plasticizer-free polypropylene modified compound composition The low tensile and tear strengths make them unsuitable for use in polymer coated industrial textiles. Exceeding 1,500 deniers results in poor surface smoothness of the fabric, which deteriorates the appearance of industrial fiber products coated with a plasticizer-free polypropylene modified compound composition. In particular, it is used in the polymer coating industrial textile products are used a lot of 1,000 filament multifilament yarn, which is a standard product is economical in terms of physical properties and low price.
상기 폴리프로필렌 직물을 제직할 때 제직 밀도는 경사 1인치 당 15 내지 40, 위사 1인치 당 15 내지 40의 제직 밀도를 지닌 평직의 직물로서, 이는 위사 및 경사의 제직 밀도가 1인치 당 15 미만이면 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품의 인장강도, 인열강도 등의 물리적 성질이 낮아지는 문제가 있고, 1인치 당 40을 초과하면 변성 폴리프로필렌을 코팅한 산업용 섬유 제품에서 요구되는 물성 이상이므로 중량만 올라가고 생산 원가만 상승시키므로 본 발명에서 구현하고자 하는 무가소제 폴리프로필렌 변성 컴파운드 조성물을 코팅한 산업용 섬유제품용 직물의 제직 밀도는 경사 1인치 당 15 내지 40, 위사 1인치 당 15 내지 40의 제직 밀도를 지닌 평직의 직물이 가장 바람직하다.When weaving the polypropylene fabric, the weaving density is a plain weave fabric having a weaving density of 15 to 40 per inch of warp yarn and 15 to 40 per inch of weft yarn, provided that the weaving density of the weft and warp yarns is less than 15 per inch. There is a problem that the physical properties such as tensile strength, tear strength, etc. of the industrial fiber products coated with a plasticizer-free polypropylene modified compound composition is lowered, and when exceeding 40 per inch, the industrial fiber products coated with modified polypropylene are required. Weaving density of the fabric for industrial textile products coated with the plasticizer-free polypropylene modified compound composition to be implemented in the present invention is 15 to 40 per inch of weft, 15 to per inch of weft yarn because it is more than physical properties to increase only the weight and increase the production cost. Most preferred are plain weave fabrics with a weave density of 40.
본 발명에서 사용된 수계 폴리올레핀 분산 수지는 산 변형 올레핀 수지, 예를들어 에틸렌폴리머계, 프로필렌폴리머계, 에틸렌프로필렌코폴리머계 및 프로필렌에틸렌부텐터폴리머계 산 변형 올레핀 수지를 사용하며, 상기 산 변형 올레핀 수지 100 중량부에 대하여 점증제 0.5 내지 5.0 중량부를 첨가하여 상온에서 점도를 500cps 내지 3,000cps로 조정한 것을 사용한다.The water-based polyolefin dispersion resin used in the present invention uses an acid-modified olefin resin, for example, an ethylene polymer, a propylene polymer, an ethylene propylene copolymer, and a propylene ethylene butene polymer-based acid modified olefin resin. 0.5 to 5.0 parts by weight of a thickener was added to 100 parts by weight of resin to adjust the viscosity at room temperature to 500 cps to 3,000 cps.
상기 수계 폴리올레핀 분산 수지는 폴리프로필렌 직물 양면에 코팅방법 또는 딥핑방법 중 어느 하나의 방법으로 처리할 수 있는데, 코팅방법은 코팅 공정 설비에 따라 Mesh Roll 방식과 Knife 방식의 2가지가 있으며, 다시 Mesh Roll 방식은 Transfer Mesh Roll 방식과 Air Mesh Roll 방식으로 나누어진다. The water-based polyolefin dispersion resin may be treated on either side of the polypropylene fabric by a coating method or a dipping method, the coating method has two types of mesh roll method and knife method according to the coating process equipment, again mesh roll The method is divided into Transfer Mesh Roll method and Air Mesh Roll method.
이때 코팅방법 중 Transfer Mesh Roll 방식에 사용되는 수계 폴리올레핀 분산 수지의 점도는 상온에 800cps 내지 1,000cps가 되어야 하며, 이는 코팅공정에서 800cps 미만일 경우에는 폴리프로필렌 직물 양면에 코팅하는 수계 폴리올레핀 분산 수지가 섬유 사이로 침투가 많이 되어 산업용 섬유제품의 부드러움이 나빠지며, 코팅 수지의 흐름성이 높아 폴리프로필렌 직물 표면으로 흘러내리는 현상이 발생되어 불량의 원인이 된다. 또한 1,000cps보다 높으면 섬유 사이로 침투되는 수지의 양이 너무 적어 접착력이 저하되고 코팅 부하가 많이 발생되어 고른 코팅이 어려우며 코팅량이 많아지는 단점이 있다. 한편, Knife 코팅 방식은 코팅 점도가 상온에서 2,000 cps 내지 3,000cps가 바람직하지만, 한번의 공정을 통하여 동시에 양면 코팅을 할 수 없을 뿐 아니라, 수계 폴리올레핀 분산 수지의 점증이 어려우며 점증제의 양이 많이 소요되어 수계 폴리올레핀 분산 수지의 물성에도 악영향을 미치고 점도를 유지하는 안정성도 떨어지므로 바람직한 방법이라 할 수 없다. At this time, the viscosity of the water-based polyolefin dispersion resin used in the transfer mesh roll method of the coating method should be 800cps to 1,000cps at room temperature, which is less than 800cps in the coating process, the water-based polyolefin dispersion resin coated on both sides of the polypropylene fabric between the fibers Due to the high penetration, the softness of the industrial textile products is deteriorated, and the flowability of the coating resin is high, which causes the phenomenon of flowing down to the surface of the polypropylene fabric, which causes defects. In addition, if it is higher than 1,000cps, the amount of resin penetrated between the fibers is too small, the adhesive strength is lowered, the coating load is generated a lot, even coating is difficult and the amount of coating has a disadvantage. In the Knife coating method, the coating viscosity is preferably 2,000 cps to 3,000 cps at room temperature. However, both coatings cannot be performed at the same time through a single process, and it is difficult to increase the number of aqueous polyolefin dispersion resins and requires a large amount of a thickener. This is not a preferred method because it adversely affects the physical properties of the aqueous polyolefin dispersion resin and also the stability of maintaining the viscosity is poor.
그리고, 딥핑 방법은 수계 폴리올레핀 분산 수지의 점도가 상온에서 500cps 내지 800cps인 것이 바람직하며, 이러한 방법은 본 발명에서 구현하고자 하는 산업용 섬유제품이 보트, 에어매트리스, 물탱크, 유류탱크용 등 특별하게 직물의 발수기능이 요구될 때 사용하는 방법으로 별도로 발수 처리를 하지 않아도 수계 폴리올레핀 분산 수지가 발수기능을 하기 때문이다. In addition, the dipping method is preferably a viscosity of the water-based polyolefin dispersion resin is 500cps to 800cps at room temperature, this method is an industrial textile products to be implemented in the present invention, such as boats, air mattresses, water tanks, oil tanks, such as special fabrics This is because the water-based polyolefin dispersion resin has a water-repellent function even when the water-repellent function of the water-repellent function is required, even if the water-repellent treatment is not performed separately.
본 발명에 따른 폴리프로필렌 변성 컴파운드 조성물은 폴리프로필렌 수지 100 중량부에 대하여, 폴리프로필렌계 변성엘라스토머 20내지 150 중량부, 폴리스티렌계 변성엘라스토머 20 내지 100 중량부, 무기필러 0.1 내지 30 중량부, 산화방지제 0.1 내지 1.0 중량부, UV 흡수제 0.1 내지 2.0 중량부, 가공활제 0.1 내지 3.0 중량부 및 착색제 0.1 내지 15 중량부를 포함하여 이루어지며, 폴리프로필렌 직물 양면에 폴리프로필렌 변성 컴파운드 조성물을 2차 코팅하여 산업용 섬유제품을 제조할 수 있다.The polypropylene modified compound composition according to the present invention is based on 100 parts by weight of polypropylene resin, 20 to 150 parts by weight of polypropylene-based modified elastomer, 20 to 100 parts by weight of polystyrene-based modified elastomer, 0.1 to 30 parts by weight of inorganic filler, antioxidant 0.1 to 1.0 parts by weight, UV absorber 0.1 to 2.0 parts by weight, 0.1 to 3.0 parts by weight of processing agent and 0.1 to 15 parts by weight of the colorant, and the secondary coating of the polypropylene modified compound composition on both sides of the polypropylene fabric industrial fiber The product can be manufactured.
상기 폴리프로필렌계 수지는 일반호모폴리프로필렌(General Homo PP), 하이크리스탈폴리프로필렌 공중합체(HCCP Homo PP), 하이크리스탈블록폴리프로필렌 공중합체(HCCP Block Copolymer PP), 랜덤코폴리프로필렌(Random Copolymer PP) 및 부틸터셔리폴리프로필렌 삼중합체(tert-PP)로 이루어진 군에서 선택된 하나 이상을 선택하여야 하며, 상기 폴리프로필렌계 수지는 용융지수(Melt Index; MI)(230℃/2.16Kg, ASTM D1238)가 1.0 g/10min 내지 5.0 g/10min인 수지를 사용하여 카렌더 공법으로 산업용 섬유제품을 제조하며, MI(230℃/2.16Kg, ASTM D1238)가 7 g/10min 내지 30 g/10min인 수지를 사용하여 압출 T-Dies 공법으로 산업용 섬유제품을 제조할 수 있기 때문에 본 발명에 따르면 카렌더 공법과 압출 T-Dies 공법 모두 적용가능하여 가공성이 우수한 산업용 섬유제품을 제조할 수 있다.The polypropylene-based resin is a general homo polypropylene (General Homo PP), a high crystal polypropylene copolymer (HCCP Homo PP), a high crystal block polypropylene copolymer (HCCP Block Copolymer PP), random copolypropylene (Random Copolymer PP ) And butyl tertiary polypropylene terpolymer (tert-PP) at least one selected from the group consisting of, the polypropylene resin has a melt index (Melt Index (MI) (230 ℃ / 2.16Kg, ASTM D1238) Is used to produce industrial textile products using a calendering method using a resin of 1.0 g / 10 min to 5.0 g / 10 min, and a resin having a MI (230 ° C./2.16 Kg, ASTM D1238) of 7 g / 10 min to 30 g / 10 min. In order to manufacture an industrial textile product by the extrusion T-Dies method, according to the present invention, both the calendering method and the extrusion T-Dies method are applicable, so that an industrial fiber product having excellent processability can be manufactured.
또한, 상기 폴리프로필렌 수지는 굴곡탄성율(ASTM D790, kg/㎠)은 6,500 내지 11,000 kg/㎠이며, 용융점(ASTM D3418, ℃)은 130 내지 150 이고, 연화점(ASTM D1525, ℃)은 110 내지 140 이며, 신장율(ASTM D638, %)은 500% 이하인 것이 바람직하다. In addition, the polypropylene resin is a flexural modulus (ASTM D790, kg / ㎠) is 6,500 to 11,000 kg / ㎠, melting point (ASTM D3418, ℃) is 130 to 150, softening point (ASTM D1525, ℃) is 110 to 140 The elongation rate (ASTM D638,%) is preferably 500% or less.
변성 폴리프로필렌을 코팅한 산업용 섬유제품을 카렌다 공법으로 제조하는 것은 폴리프로필렌 변성 컴파운드 조성물의 코팅 두께가 한면 기준으로 0.2 mm를 초과 할 때 사용하는 공법으로, 용융지수가 3 이상이면 흐름성이 너무 높아 변성 폴리프로필렌 코팅 산업용 섬유제품용 시트 제조시 처짐현상이 발생하기 때문에 카렌더 공정을 적용하기가 어려워지고, 압출 T-Dies 공법은 폴리프로필렌 변성 컴파운드 조성물의 코팅 두께가 한면 기준으로 0.05 mm 내지 1.0 mm일 때 사용하는 공법으로 용융지수가 20 이하이면 수지의 흐름성이 나빠져서 압출기에 부하가 많이 걸리고 Neck In이 심하여 변성 폴리프로필렌을 코팅한 산업용 섬유제품의 중앙과 양 측면 간의 코팅 두께 편차가 심하여 제품을 원하는 폭으로 생산하기가 어려운 문제가 야기될 수 있다. 이를 극복하기 위해서는 양 측면 컷팅 폭이 넓어져야 하므로 손실이 많아지는 단점이 발생할 수 있다. 용융지수가 30 이상이면 압출 T-Dies 공법을 적용하기가 어려운데 이는 흐름성이 너무 빨라서 압출 가공 속도를 높여야 하기 때문에 원하는 최소한의 코팅 두께인 한면 기준으로 0.1 mm 이상인 제품을 생산하기 힘들 뿐 아니라 코팅 수지와 직물 간 면접합 속도가 너무 빨라서 접착력이 떨어질 수 있다.The manufacture of industrial fiber products coated with modified polypropylene by the calendering method is used when the coating thickness of the polypropylene modified compound composition exceeds 0.2 mm based on one side. When the melt index is 3 or more, the flowability is too high. Modified polypropylene coating It is difficult to apply the calendering process because sagging occurs in the manufacturing of sheets for industrial textile products, and the extrusion T-Dies method has a coating thickness of 0.05 to 1.0 mm based on one side of the polypropylene modified compound composition. When the melt index is 20 or less, the flowability of the resin is worsened, so that the extruder takes a lot of load and the neck in is severe, so that the coating thickness variation between the center and both sides of the industrial fiber product coated with modified polypropylene is severe. Problems that are difficult to produce in breadth can arise. In order to overcome this, both side cutting widths must be widened, which may result in a loss. If the melt index is more than 30, it is difficult to apply the extrusion T-Dies method, because the flowability is so fast that the extrusion processing speed must be increased. The bond rate between the fabric and the fabric may be so high that the adhesion may be reduced.
굴곡탄성률의 경우 유연성과 밀접한 관계가 있는 것으로, 6,500 kg/㎠ 미만이면 외부 응력에 대한 복원력이 떨어지고, 11,000 kg/㎠을 초과하게 되면 변성 폴리프로필렌을 코팅한 산업용 섬유제품의 부드러움이 나빠져서 딱딱한 느낌을 주며 쵸크마크가 발생할 확률이 높아 코팅용 컴파운드 조성물을 결정할 때 연성을 부여하는 수지를 많이 사용하여야 하는데 이는 컴파운드 조성물의 단가를 높이고 물성의 저하를 가져오며 접착력이 저하되는 단점이 발생할 수 있다.Flexural modulus is closely related to flexibility, and if it is less than 6,500 kg / ㎠, the resilience against external stress falls, and if it exceeds 11,000 kg / ㎠, the softness of industrial fiber products coated with modified polypropylene worsens and gives a hard feeling. It has a high probability of occurrence of chalk marks, so when the coating compound composition is determined, a resin that provides ductility should be used. This may increase the cost of the compound composition, lower the physical properties, and lower the adhesive strength.
용융점의 경우는 130℃ 미만이면 폴리프로필렌 타포린과 같은 산업용 섬유제품의 열 안정성이 저하되고, 160℃를 초과하게 되면 폴리프로필렌 변성 컴파운드 조성물의 시트 제조시 높은 가공온도가 필요해지는 문제가 야기될 수 있다.If the melting point is less than 130 ℃ thermal stability of industrial textile products such as polypropylene tarpaulin is lowered, if it exceeds 160 ℃ may cause a problem that a high processing temperature is required when manufacturing the sheet of the polypropylene modified compound composition. .
연화점의 경우는 110℃ 미만이면 변성 폴리프로필렌을 코팅한 산업용 섬유제품의 열에 대한 보지성이 나빠져 엠보스되어 있는 타포린의 경우는 엠보스 무늬의 선명성이 저하되며, 140℃를 초과하게 되면 엠보싱을 할 때 높은 가공온도를 필요로 하기 때문에, 기계에 부하가 많이 발생할 수 있다.If the softening point is less than 110 ℃, the retaining ability of the industrial textile product coated with modified polypropylene becomes poor, and in the case of tarpaulin embossed, the sharpness of the embossed pattern is lowered. Because of the high processing temperatures required, the machine can be heavily loaded.
신장률의 경우는 500%를 초과하게 되면, 열에 의한 수축이 쉽게 발생하기 때문에, 변성 폴리프로필렌을 코팅한 산업용 섬유제품의 열치수 안정성이 저하될 수 있다.In the case of the elongation rate exceeding 500%, since shrinkage by heat occurs easily, the thermal dimensional stability of the industrial fiber product coated with modified polypropylene may be lowered.
이러한 폴리프로필렌계 수지의 특성은 최종제품의 열 안정성 및 굴곡 강도에 영향을 미치게 되며, 변성 폴리프로필렌을 코팅한 산업용 섬유제품 제조용 컴파운드 조성물을 제조할 때 압출 공법이 적용 가능하다.The characteristics of the polypropylene resin affects the thermal stability and the flexural strength of the final product, it is possible to apply an extrusion method when producing a compound composition for manufacturing industrial fiber products coated with modified polypropylene.
상기 폴리프로필렌계 변성 엘라스토머 수지는 메탈로젠 촉매법으로 제조한 폴리프로필렌에틸렌 공중합 플라스토머(m-PEPP), 폴리프로필렌옥텐 공중합 플라스토머(m-POPP), 폴리프로필렌헥센 공중합 플라스토머(m-PHPP), 폴리프로필렌부텐 공중합 플라스토머(m-PBPP) 및 폴리올레핀블록코폴리머로 이루어진 군에서 선택된 하나 이상을 포함하여 이루어지는데, 이러한 폴리프로필렌계 변성 엘라스토머는 폴리프로필렌 타포린과 같은 산업용 섬유제품을 구성하는 층 중에 코팅층 컴파운드 조성물의 탄성과 내한성을 높여주는 역할을 하며, 폴리프로필렌 수지와 상용성이 아주 뛰어나다. The polypropylene-based modified elastomer resin is polypropylene ethylene copolymerized plastomizer (m-PEPP), polypropylene octene copolymerized plastomizer (m-POPP), polypropylene hexene copolymerized plasomer (m) -PHPP), polypropylene butene copolymerized plastomers (m-PBPP) and polyolefin block copolymers, and one or more selected from the group consisting of such polypropylene-based modified elastomers for industrial textile products such as polypropylene tarpaulin Among the constituting layers, it serves to increase the elasticity and cold resistance of the coating layer compound composition, and excellent compatibility with the polypropylene resin.
상기 폴리프로필렌계 변성 엘라스토머 수지는 카렌다 공법으로 제조하는 경우에는 물성 항목 중 MI(Melt Index, 용융지수)(230℃/2.16Kg, ASTM D1238, g/10min)가 1 내지 3인 수지를, 압출 T-Dies 공법으로 제조하는 경우에는 MI(Melt Index)(230℃/2.16Kg, ASTM D1238, g/10min)가 5 내지 15인 수지를 사용하며, 경도(ASTM D2240, Shore A)는 60 내지 80이며, 총 결정도(Total Crystallinity)가 20% 이하이다. When the polypropylene-based modified elastomer resin is manufactured by the calender method, the resin having an MI (Melt Index, Melt Index) (230 ° C./2.16 Kg, ASTM D1238, g / 10 min) of 1 to 3 among physical properties is extruded. When manufactured by the Dies method, a resin having a MI (Melt Index) (230 ° C / 2.16Kg, ASTM D1238, g / 10min) of 5 to 15 is used, and the hardness (ASTM D2240, Shore A) is 60 to 80. The total crystallinity is less than 20%.
이때, 경도가 60 미만이면 컴파운드 조성물의 인장강도 및 인열이 나빠지며, 80을 초과하면 컴파운드 조성물의 부드러움이 저하되어 최종 제품인 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품이 뻣뻣해진다. 총 결정도(Total Crystallinity)가 20을 초과하면 탄성과 내한성에 나쁜 영향을 주며, 심체로 사용하는 폴리에스테르 직물과 컴파운드 조성물 간의 접착성도 나빠질 수 있다.At this time, when the hardness is less than 60, the tensile strength and tear of the compound composition worsens, and when the hardness is greater than 80, the softness of the compound composition is lowered and the final product of the polypropylene modified compound coating industrial textile product is stiff. If the total crystallinity exceeds 20, the elasticity and cold resistance will be adversely affected, and the adhesion between the core polyester fabric and the compound composition may worsen.
상기 폴리스티렌계 변성엘라스토머는 폴리스티렌부타디엔공중합체(SBS), 폴리스티렌이소프렌공중합체(SIS), 폴리스티렌에틸렌부타디엔블록공중합체(SEBS), 폴리스티렌에틸렌프로필렌블록공중합체(SEPS), 수소부가폴리스티렌에틸렌부타디엔엘라스토머(HSEBS)로 이루어진 군에서 선택된 하나 이상을 포함하여 이루어지는데, 상기 컴파운드 조성물로 코팅한 산업용 섬유제품의 인장성, 인열성, 유연성 및 굴곡강도를 향상시켜 준다.The polystyrene-based modified elastomer is polystyrene butadiene copolymer (SBS), polystyrene isoprene copolymer (SIS), polystyrene ethylene butadiene block copolymer (SEBS), polystyrene ethylene propylene block copolymer (SEPS), hydrogenated polystyrene ethylene butadiene elastomer (HSEBS It comprises one or more selected from the group consisting of, to improve the tensile, tearing, flexibility and flexural strength of the industrial textile product coated with the compound composition.
상기 폴리스티렌 변성엘라스토머는 인장강도는 3,000 kgf/cm2를 초과하고, 파단점 신장률이 800% 내지 1,500%인 고탄성 엘라스토머인데, 100 중량부를 초과하여 함유되면 신장률이 높은 물질이기 때문에 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품의 열에 대한 치수안정성을 감소시키며, 고무와 거동이 비슷해져 2차 가공이 어려워지고 원가상승의 원인이 될 수 있다.The polystyrene modified elastomer is a high elastic elastomer having a tensile strength of more than 3,000 kgf / cm 2 and an elongation at break of 800% to 1,500%. It reduces the dimensional stability against heat of textile products and the similar behavior with rubber can make secondary processing difficult and cause the cost to rise.
상기 무기필러는 탄산칼슘, 탈크, 클레이, 마그네사이트, 수산화알루미늄 및 수산화마그네슘으로 이루어진 군에서 선택된 하나 이상으로 이루어진다. 상기 30 중량부를 초과하여 함유되면 쵸크마크가 발생할 확률이 높아지고 비중이 높아져서 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품의 특징인 경량성을 저해할 수 있다. The inorganic filler consists of at least one selected from the group consisting of calcium carbonate, talc, clay, magnesite, aluminum hydroxide and magnesium hydroxide. When the content is more than 30 parts by weight, the probability of occurrence of the chalk mark is increased and the specific gravity is increased, thereby inhibiting the lightness which is a characteristic of the polypropylene modified compound coating industrial textile product.

상기 UV 흡수제는 벤조페논계, 페닐실리케이트, 비스(2,2,6,6-테트라메틸-4-피페리디닐)세바케이트, 2-(3'-5'-디-터셔리-부틸-2'-히드록시페닐)-5-클로로벤조트리아졸, 2-(3,5-디-터셔리-페닐-2-히드록시페닐)벤조트리아졸, 2-(2'-히드록시-5-메틸페닐)벤조트리아졸, 2-(3'-터셔리-부틸-2'-히드록시-5'-메틸페닐)-5-클로로벤조트리아졸 및 힌다드아민계 자외선 안정제로 이루어진 군에서 선택된 하나 이상을 포함하여 이루어지는데, 자외선으로부터 섬유 코팅용 폴리프로필렌 컴파운드 조성물의 물성변화를 차단하여 안정화시키고, 변색 및 노화를 방지하여 내후성 및 내광성을 향상시켜 준다.The UV absorber is benzophenone series, phenyl silicate, bis (2,2,6,6-tetramethyl-4-piperidinyl) sebacate, 2- (3'-5'-di-tertiary-butyl-2 '-Hydroxyphenyl) -5-chlorobenzotriazole, 2- (3,5-di-tertiary-phenyl-2-hydroxyphenyl) benzotriazole, 2- (2'-hydroxy-5-methylphenyl ) Benzotriazole, 2- (3'-tertiary-butyl-2'-hydroxy-5'-methylphenyl) -5-chlorobenzotriazole and a hindered amine based UV stabilizer It is made, by stabilizing by blocking the change in physical properties of the polypropylene compound composition for fiber coating from ultraviolet rays, and prevents discoloration and aging to improve weather resistance and light resistance.
상기 가공활제는 스테아르산아연, 올레아미드, 에루카아미드, 스테아르아미드, 베헨아미드, 지방산아민 및 불소수지로 이루어진 군에서 선택된 하나 이상을 포함하여 이루어지는데, 3.0 중량부를 초과하여 사용하게 되면 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품의 코팅층 접착력이 감소하게 될 수 있다.The processing lubricant comprises one or more selected from the group consisting of zinc stearate, oleamide, erucamide, stearamide, behenamide, fatty acid amine and fluororesin, and when used in excess of 3.0 parts by weight of polypropylene modified Compound coating The coating layer adhesion of the industrial textile products may be reduced.
이러한 가공활제는 압출기 실린더 및 스크류와 컴파운드 조성물 간에 마찰계수를 낮춰주기 때문에 압출공정 시에 원활한 압출을 제공하게 하고, 실린더 및 스크류에 조성물 잔존물이 남는 것을 차단하여 잔존물이 탄화되는 것을 예방하기 때문에 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품의 코팅층의 표면 불량률을 감소시킬 수 있다. 또한, 카렌더 공정을 이용하여 폴리프로필렌 변성 컴파운드 시트를 제조할 때에는 카렌더로부터 이형성을 부여하는 가공조제의 역할을 한다.This processing lubricant lowers the coefficient of friction between the extruder cylinder and the screw and the compound composition to provide smooth extrusion during the extrusion process and prevents the residue from carbonizing by blocking the composition residue from remaining in the cylinder and screw. Modified compound coating can reduce the surface failure rate of the coating layer of the industrial textile products. In addition, when producing a polypropylene modified compound sheet using a calender process, it serves as a processing aid for imparting releasability from the calender.
상기 폴리프로필렌 변성 컴파운드 코팅 산업용 섬유제품을 제조하기 위하여, 폴리프로필렌 변성 컴파운드 조성물은 도 1에 도시된 바와 같이 니더(Kneader) 또는 믹서기를 이용하여 1차 혼련하고, 1차 혼련이 끝난 조성물을 압출기에 넣고 용융혼합하면서 압출시키는데, 이때 압출 조건은 아래와 같다.In order to manufacture the polypropylene modified compound coated industrial textile products, the polypropylene modified compound composition is kneaded first using a kneader or a mixer as shown in FIG. 1, and the first kneaded composition is extruded to an extruder. Into the extrusion while melting and mixing, the extrusion conditions are as follows.
호퍼온도 : 상온 Hopper temperature: Room temperature
실린더온도 : 140℃ 내지 170℃ Cylinder temperature: 140 ℃ to 170 ℃
다이(Die)온도 : 180℃ 내지 210℃Die temperature: 180 ℃ to 210 ℃
싱글스크류 타입 압출기 : L/D=36/1 이상Single screw type extruder: L / D = 36/1 or more
트윈스크류 타입 압출기 : L/D=26/1 이상Twin screw type extruder: L / D = 26/1 or more
상기 압출조건으로 압출된 조성물은 수냉과정을 거치고, 컷팅해서 펠렛(Pellet)화 시키고, 유수분리의 과정을 거친 후에 건조시켜 보관한다. The composition extruded under the extrusion conditions is subjected to a water cooling process, cut and pelletized, and dried and stored after undergoing a process of oil and water separation.
그리고, 수계 폴리올레핀 분산 수지를 이용하여 폴리프로필렌 직물을 1차 코팅하는 경우에는 Transfer Mesh Roll 방법과 딥핑 방법이 있다. 상기 Transfer Mesh Roll 방법은 도 2에 나타난 바와 같이 액상 형태의 수계 폴리올레핀 분산 수지를 폴리프로필렌 직물에 건조 후 중량 기준으로 100g/㎡ 내지 120g/㎡을 양면에 코팅한 다음 120℃ 내지 150℃의 온도가 유지되는 열풍 건조 챔버를 통과시켜서 수분이 완전히 제거되도록 건조시킨다. 이때 열풍 건조 챔버는 반드시 직물 양 측면을 클립으로 고정시켜서 통과시키는 방식으로 해야 하는데 이는 직물의 열변형을 막아주기 위해서이다. 수분이 완전히 제거되지 않으면 접착에 나쁜 영향을 준다. 그리고, 딥핑 방식은 도 3에 나타난 바와 같이 망글 공정을 통하여 딥핑한 수계 폴리올레핀 분산 수지를 Squeezing Roll로 짜서 필요한 양만큼 취하는 공정으로 망글의 압력으로 취하는 양을 결정한다. 이 방식도 공히 건조 후 중량 기준으로 100g/㎡ 내지 120g/㎡을 양면 코팅한 후 120℃ 내지 150℃의 온도가 유지되는 열풍 건조 챔버를 통과시켜서 수분이 완전히 제거되도록 건조시킨다. 폴리프로필렌 직물에 수계 폴리올레핀 분산 수지를 Transfer Mesh Roll이나 딥핑 방식으로 양면 코팅을 한 후 IR 가열 챔버(180 ± 5℃)와 IR 가열 드럼(190 ± 5℃) 사이로 통과시키면서 엠보 압착롤을 통해 라미네이션 시켜 변성 폴리프로필렌을 코팅한 산업용 섬유제품을 제조하며, 엠보 압착 라미네이션 Roll은 스틸 냉각롤과 실리콘 또는 고무 냉각롤로 구성되며 엠보싱 역할도 동시에 수행한다. 사용 압력은 5 kgf/㎠ 이상이 바람직하며, Roll의 직경은 클수록 접착에 유리하다.In the case of primary coating of a polypropylene fabric using an aqueous polyolefin dispersion resin, there are a transfer mesh roll method and a dipping method. The transfer mesh roll method is a water-based polyolefin dispersion resin of the liquid form as shown in Figure 2 and then coated on both sides 100g / ㎡ to 120g / ㎡ by weight based on the weight of the polypropylene fabric and then the temperature of 120 ℃ to 150 ℃ Pass the hot air drying chamber maintained to dry to remove moisture completely. At this time, the hot air drying chamber must be fixed by passing both sides of the fabric with a clip in order to prevent heat deformation of the fabric. If the moisture is not removed completely, it will adversely affect the adhesion. In addition, the dipping method is a process of squeezing the water-based polyolefin dispersion resin dipped through the mangle process using a squeezing roll and taking as much as necessary to determine the amount taken by the mangle pressure. This method is also coated on both sides of 100g / ㎡ to 120g / ㎡ on the basis of weight after drying and then passed through a hot air drying chamber maintained at a temperature of 120 ℃ to 150 ℃ to dry to remove moisture completely. Water-based polyolefin dispersion resin is coated on both sides of polypropylene fabric by transfer mesh roll or dipping method, and then laminated through emboss pressing roll while passing between IR heating chamber (180 ± 5 ℃) and IR heating drum (190 ± 5 ℃). It manufactures industrial fiber products coated with modified polypropylene, and embossing lamination roll is composed of steel cooling rolls and silicon or rubber cooling rolls, and also embossing. The use pressure is preferably 5 kgf / cm 2 or more, and the larger the diameter of the roll, the better the adhesion.
