Abstract
Description
본 발명은 산업용 안전망에 사용되는 폴리에스터계 직물의 밀림 및 재단부의 탈봉(올풀림)을 방지하여 견직성을 향상시키고 동시에 난연성을 부가하기 위한 코팅 조성물 및 이의 제조방법에 관한 것으로서, 보다 구체적으로 무독성의 환경친화적인 수용성 바인더 조성물 및 할로겐프리 난연제 조성물을 포함하는 안전망용 코팅 조성물 및 이의 제조방법에 대한 것이다.The present invention relates to a coating composition and a method for manufacturing the same, which are used for industrial safety nets, to prevent slipping and detachment (unraveling) of the cutting part to improve the texture and at the same time to add flame retardancy, and more specifically, to a non-toxic A coating composition for a safety net comprising an environmentally friendly water-soluble binder composition and a halogen-free flame retardant composition and a method for manufacturing the same.
산업용 안전망은 건설 공사 현장에서 작업자의 접근 또는 추락을 방지하고, 낙하물로 인한 피해를 방지하기 위해 사용하는 안전가설물 중 하나로서, 종류에는 수직보호망, 추락방호망, 낙하물 방지망, 수직형 추락방망, 비계망 등이 있다. 일반적으로 산업용 안전망은 폴리에스터계, 폴리프로필렌계, 폴리에틸렌계(주로 HDPE), 나일론계 소재의 섬유를 원사로 하여 망 형태로 직물을 제직하여 제조되고, 추가적으로 내구성을 향상시키고 방수, 방염, 방오, 난연 등의 기능을 부가하기 위하여 PVC, 할로겐계 물질 등을 보강재로 하여 상기 망에 도포, 함침, 코팅시키는 방법으로 제조된다. Industrial safety net is one of the safety facilities used to prevent workers from approaching or falling at construction sites and to prevent damage from falling objects. nets, etc. In general, industrial safety nets are manufactured by weaving fabrics in the form of nets using fibers of polyester, polypropylene, polyethylene (mainly HDPE), and nylon as yarns, and additionally improve durability and have waterproof, flameproof, antifouling, In order to add functions such as flame retardancy, it is manufactured by applying, impregnating, or coating the net with PVC, halogen-based materials, etc. as reinforcing materials.
이러한 산업용 안전망 제조 기술 중에서도 특히 폴리에스터(예를 들어, PET(polyethylene terephthalate, 폴리에틸렌 테레프탈레이트)의 고강력사 원단에 PVC 수지를 코팅하는 제조 방법이 일본에서 처음 상용화된 이후 국내에도 동일한 제조 방법이 도입 및 정착되어 현재에도 해당 제조 방법이 90% 이상의 시장 점유율을 기록하고 있다.Among these industrial safety net manufacturing technologies, in particular, since the manufacturing method of coating PVC resin on high-tenacity yarn fabric of polyester (for example, polyethylene terephthalate (PET)) was first commercialized in Japan, the same manufacturing method has been introduced and developed in Korea. It has been established and even today, the manufacturing method has a market share of over 90%.
그러나 종래 기술은 환경독성물질인 염소(Chlorine, Cl), 삼산화안티몬(Antimony Trioxide), 프탈레이트계 가소제(예를 들어, DINP (Diisononyl phthalate, 다이아이소노닐 프탈레이트)), 희석제로서의 유기용제(예를 들어, 톨루엔) 등이 가공과정 중 발생하기 때문에 대기오염 방지를 위한 저감시설을 필요로 할 뿐만 아니라, 이러한 유해물질이 완성제품에도 다량 남아있다는 것이 가장 큰 문제점으로 지적되고 있다.However, the prior art is environmentally toxic substances such as chlorine (Cl), antimony trioxide, phthalate-based plasticizers (eg DINP (Diisononyl phthalate, diisononyl phthalate)), organic solvents as diluents (eg , toluene), etc. are generated during the processing process, so it is pointed out as the biggest problem that a reduction facility is required to prevent air pollution, and that a large amount of these harmful substances remain in the finished product.
특히, PVC(Polyvinyl Chloride, 폴리비닐 클로라이드)는 염화비닐을 중합한 것으로서 염소가 대량으로 들어있어 생산, 사용, 폐기과정에서 유독물질이 많이 나오고, 소각시 다이옥신으로 대표되는 환경 호르몬이 대량으로 발생하기 때문에 생물에게 매우 유독하고 위험하여 지정폐기물로 분류되어 반드시 분리수거를 해야하는 품목 중 하나이다. 안티몬은 난연화제로서 주로 삼산화안티몬으로 PVC에 첨가되나, 독성 중금속이기 때문에 피부와 눈에 대한 자극제이며, 폐와 위장에도 독성을 나타내는 물질이다. 프탈레이트는 플라스틱 가소제로 특히 PVC를 부드럽게 만들기 위해 쓰이고 있으나, 내분비교란물질이자 환경오염물질로서 현재 국내는 10종의 프탈레이트를 규제대상으로 정하고 있고, 추가로 15종, 18종 규제로 규제폭이 확대될 예정이다.In particular, PVC (Polyvinyl Chloride) is a polymerized vinyl chloride, and contains a large amount of chlorine, so a lot of toxic substances are released during the production, use, and disposal process, and when incinerated, a large amount of environmental hormones represented by dioxins are generated. Therefore, it is very toxic and dangerous to organisms, and is classified as designated waste and is one of the items that must be collected separately. As a flame retardant, antimony is added to PVC mainly as antimony trioxide, but since it is a toxic heavy metal, it is an irritant to the skin and eyes, and is also toxic to the lungs and stomach. Phthalates are used as plastic plasticizers to make PVC soft, but as endocrine disruptors and environmental pollutants, 10 types of phthalates are currently designated as regulated targets in Korea, and the scope of regulation will be expanded with additional 15 and 18 types of regulations. Is expected.
더욱이 종래 기술은 이와 같은 규제물질과 유기용제들을 사용하여 160℃ 이상의 열을 가해 수지를 녹여 원단에 고착시키는 방식으로 제품을 제조하기 때문에 에너지 사용이 과다하고, 이로인해 발생되는 매연과 냄새를 저감시키기 위해 2차 배기시설의 설치를 필요로 하기 때문에 막대한 운전비용과 설비비용이 들어가게 된다. 그럼에도 불구하고, PVC를 주성분으로 하는 종래의 코팅 조성물로 코팅된 PET 안전망은 이종수지와 규제물질 사용으로 인해 재활용이 불가하고, 지정폐기물로 분류되어 있기 때문에 사용후에는 반드시 분리수거 해야한다.Moreover, since the prior art uses such regulated substances and organic solvents to manufacture products by applying heat of 160 ° C. or higher to melt the resin and fix it to the fabric, energy consumption is excessive, and it is difficult to reduce the smoke and odor generated by this. Since the installation of a secondary exhaust system is required for ventilation, huge operating and facility costs are incurred. Nevertheless, PET safety nets coated with a conventional coating composition containing PVC as a main component cannot be recycled due to the use of heterogeneous resins and regulated substances, and are classified as designated waste, so they must be collected separately after use.
또한, 종래 기술은 제조공정시 원단을 160℃ 이상으로 고온 가공처리 해야하기 때문에 고온에서도 변형이 적도록, 수축률이 낮은 저수축사를 사용해야만 한다. 일반적인 폴리에스터계 안전망의 제조공정상 용융방사, 재직, 망포재직 및 연결사 열처리 과정을 거쳐 형성된 직물지의 경우, 고온 열처리 과정에서 직물지의 변형이 일어나지 않도록 원단의 변사부를 물리적으로 고정해야 하는데, 이때 기본 원단의 5%가 폐기되어 원단 손실이 발생한다는 단점이 있다. In addition, in the prior art, since the fabric must be processed at a high temperature of 160 ° C. or higher during the manufacturing process, a low-shrinkage yarn with a low shrinkage rate must be used so that deformation is small even at high temperatures. In the case of woven paper formed through melt spinning, weaving, mesh weaving, and connecting yarn heat treatment processes in the manufacturing process of a general polyester safety net, it is necessary to physically fix the twist part of the fabric so that the woven paper does not deform during the high temperature heat treatment process. At this time, the basic fabric There is a disadvantage that 5% of the waste is discarded, resulting in fabric loss.
그러나, 이러한 유독성의 코팅 조성물 및 코팅 공정시의 단점을 회피하고자 단순히 통상적인 원사를 사용하여 제조된 안전망을 보강재 없이, 즉 코팅하지 않고 사용할 경우, 원사의 물리적 결합만으로는 외부 장력에 저항하는 힘이 부족하여 밀림 현상이 빈번히 발생하게 되고(도 2), 직물 조직 또한 직교된 부분의 결합이 안정적으로 고정되지 않아 재단부의 탈봉이 빈번히 발생하게 될 것이다(도 3). 결과적으로는 안전망 가공, 재단 및 설치 등의 작업시 효율이 떨어지게 된다.However, in order to avoid such toxic coating composition and disadvantages in the coating process, when a safety net manufactured using simply conventional yarn is used without a reinforcing material, that is, without coating, the strength to resist external tension is insufficient only by the physical bonding of the yarn. As a result, shedding occurs frequently (FIG. 2), and the fabric tissue is also not stably fixed to the bond of the orthogonal portion, so that the cutting portion will be disconnected frequently (FIG. 3). As a result, the efficiency of work such as safety net processing, cutting and installation is reduced.
이처럼, 종래 기술은 환경적, 에너지적, 자원 재활용적 및 비용적 측면에서도 다양한 문제점을 가지고 있어, 에너지면에서 효율적이고, 재활용이 가능하고, 유독성 및 유해성 물질을 사용하지 않아 친환경적이면서도 견직성 및 난연성을 향상시킬 수 있는 산업용 안전망 제조 기술이 요구되고 있다.As such, the prior art has various problems in terms of environmental, energy, resource recycling, and cost, and is energy efficient, recyclable, and eco-friendly because it does not use toxic and hazardous materials, but also has robustness and flame retardancy. There is a demand for industrial safety net manufacturing technology that can improve performance.

첫째, PVC 코팅 조성물을 고온(160℃ 이상)에서 녹여 원단에 고착시키는 종래의 방식과는 달리, 본 발명의 안전망용 코팅 조성물은 할로겐(예를 들어, 염소, 브롬 등), 안티몬, 프탈레이트와 같은 유독성 물질을 포함하지 않고 수용성의 아크릴계 공중합체를 포함하고 있어 120℃ 이하의 온도에서 수분을 제거하여 원단에 고착시키는 방식을 이용함으로써, 독성물질 및 매연이 발생하지 않아 대기오염 방지시설을 추가로 필요로 하지 않으므로 운전비용과 설비비용 감소 효과는 물론, 에너지 및 온실가스 저감 효과가 있다.First, unlike the conventional method of melting the PVC coating composition at a high temperature (160 ° C. or more) and fixing it to the fabric, the coating composition for safety nets of the present invention is halogen (eg, chlorine, bromine, etc.), antimony, phthalate, etc. It does not contain toxic substances and contains a water-soluble acrylic copolymer, so it removes moisture at a temperature of 120 ° C or lower and fixes it to the fabric, so toxic substances and smoke do not occur, so air pollution prevention facilities are additionally required. Since it is not used as a system, it has the effect of reducing operating costs and facility costs as well as reducing energy and greenhouse gas emissions.
둘째, 종래 기술의 고온가공 하에서는 일반적인 원사의 경우 수축률이 높아 가공이 쉽지 않기 때문에 저수축사를 사용하게 되는데, 이와 같은 저수축사는 원사의 강도(g/데니아)가 낮아 물리적인 결합에 의한 견직성이 결여되어 외부 장력에 의한 밀림 및 재단부의 연쇄 탈봉 현상이 빈번하게 일어난다는 문제가 있으나, 본 발명은 저온가공이 가능하여 인장강도가 뛰어난 일반 고강력사를 사용할 수 있으므로, 밀림 및 탈봉 현상이 개선된 견고한 안전망 직물지를 얻을 수 있다.Second, in the case of high-temperature processing in the prior art, low-shrinkage yarn is used because it is not easy to process because the shrinkage rate is high in the case of general yarn. However, since the present invention can be processed at a low temperature and can use general high-tenacity yarn with excellent tensile strength, the present invention is robust with improved slippage and peeling phenomena. You can get safety net fabric.
셋째, 본 발명의 코팅 조성물은 안전망에 난연성을 부여하기 위한 난연제 조성물을 포함함에 있어 친환경 소재인 구아니딘계 및 인계 난연제와 같은 할로겐프리 난연제를 포함하고 있을 뿐만 아니라, 아크릴계 공중합체 합성시 인계 모노머를 첨가하여 제조함으로써 난연성을 더욱 증진시키는 효과가 있다.Third, the coating composition of the present invention includes halogen-free flame retardants such as guanidine-based and phosphorus-based flame retardants, which are environmentally friendly materials, as well as adding a phosphorus-based monomer when synthesizing an acrylic copolymer, as it includes a flame retardant composition for imparting flame retardancy to a safety net. By manufacturing it, there is an effect of further enhancing the flame retardancy.
넷째, 본 발명의 코팅 조성물은 친환경적인 수용성 물질들을 이용하고 있어 제조공정 중에 유독 물질이 발생하지 않고, 완제품에도 독성물질이 남지 않으며, 사용 후 재활용이 가능하다. Fourth, since the coating composition of the present invention uses environmentally friendly water-soluble materials, no toxic substances are generated during the manufacturing process, no toxic substances are left in the finished product, and it can be recycled after use.
다섯째, 본 발명의 수성 코팅 조성물을 이용하여 폴리에스터계 안전망 원단을 코팅한 경우, 종래 유성의 PVC 코팅 조성물을 이용하였을 때보다 완제품(안전망 직물지)에서 20% 이상 경량화가 가능하므로, 안전망 설치시 작업을 보다 용이하게 할 수 있다.Fifth, when the polyester-based safety net fabric is coated using the water-based coating composition of the present invention, it is possible to reduce the weight of the finished product (safety net fabric) by 20% or more compared to when using a conventional oil-based PVC coating composition, so work when installing the safety net can be made more easily.
본 발명의 효과들은 이상에서 언급된 효과로 제한되지 않으며, 언급되지 않은 또 다른 효과들은 아래의 기재로부터 통상의 기술자에게 명확하게 이해될 수 있을 것이다.The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

The 2-methyl-2-propenoic acid porphinicobis (oxy-2,1-ethanediyl) ester is also available as KAYAMER PM-2 from NK Co., Ltd. (Nippon Kayaku/Japan Oil Corporation).
보다 구체적으로, 상기 아크릴계 공중합체 에멀젼은, Tg(glass transition temperature, 유리전이 온도) 값을 고려하여 아크릴계 모노머로서 메틸 아크릴레이트, 에틸 아크릴레이트, 뷰틸 아크릴레이트, 2-에틸헥실 아크릴레이트, 메틸 메타크릴레이트, N-뷰틸 메타크릴레이트, 아크릴산, 메타크릴산, 2-하이드록시에틸 메타크릴레이트(2-HEMA), 2-하이드록시에틸아크릴레이트, 아크릴아마이드, 스티렌, 아크릴로나이트릴 및 N-메틸 아크릴아마이드 중에서 선택되는 적어도 하나 이상의 모노머와, 상기 인계 모노머로서 2-메틸-2-프로펜산 포피니코비스(옥시-2,1-에탄디일)에스터를 일정비율로 혼합하고 유화제를 이용하여 유화중합함으로써 합성된 공중합체를 포함한다.More specifically, the acrylic copolymer emulsion contains methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, and methyl methacryl as acrylic monomers in consideration of the Tg (glass transition temperature) value. lactate, N-butyl methacrylate, acrylic acid, methacrylic acid, 2-hydroxyethyl methacrylate (2-HEMA), 2-hydroxyethyl acrylate, acrylamide, styrene, acrylonitrile and N-methyl By mixing at least one monomer selected from acrylamide and 2-methyl-2-propenoic acid porphinicobis (oxy-2,1-ethanediyl) ester as the phosphorus monomer in a certain ratio and emulsion polymerization using an emulsifier including synthesized copolymers.
이때 생성된 공중합체(또는 공중합체 에멀젼)은 Tg 값이 -10~30℃인 것이 바람직하다. 보다 바람직하게는, 폴리에스터계 안전망의 완제품에서의 내수성, 내구성 및 점착성을 고려하여 Tg가 10-20℃인 것이 적절하다. 또한 상기 모노머들의 혼합 비율은 안전망 직물의 견직성을 강화시키기 위한 필요 강직 정도에 따라 결정될 수 있다.At this time, the resulting copolymer (or copolymer emulsion) preferably has a Tg value of -10 to 30 °C. More preferably, considering the water resistance, durability and adhesiveness of the finished product of the polyester safety net, it is appropriate that the Tg is 10-20°C. In addition, the mixing ratio of the monomers may be determined according to the degree of rigidity required to enhance the stiffness of the safety net fabric.
상기 유화중합시 사용되는 유화제 역시, 난연성을 극대화시키기 위하여 인계 유화제 중에서 선택되며, 구체적으로는 폴리옥시에틸렌 트리데실 포스페이트 에스터(polyoxyethylene tridecyl phosphate ester)(Solvay사의 RHODAFAC RS-610 E)와 같은 인계 유화제가 바람직하나, 이에 한정되는 것은 아니다. 상기 인계 유화제는 음이온성 유화제 또는 비이온성 유화제로부터 선택되는 하나 이상의 유화제와 함께 혼합유화제로 사용될 수 있다. 상기 음이온성 유화제 및 비이온성 유화제는 본 기술 분야에 알려져 있는 물질들 중에서 비제한적으로 선택될 수 있다.The emulsifier used during the emulsion polymerization is also selected from phosphorus-based emulsifiers to maximize flame retardancy, specifically, phosphorus-based emulsifiers such as polyoxyethylene tridecyl phosphate ester (Solvay's RHODAFAC RS-610 E) Preferred, but not limited thereto. The phosphorus-based emulsifier may be used as a mixed emulsifier together with one or more emulsifiers selected from anionic emulsifiers and nonionic emulsifiers. The anionic emulsifier and nonionic emulsifier may be selected from materials known in the art without limitation.
이처럼 본 발명의 수용성 바인더 조성물은 인계 모노머 및 인계 유화제를 포함하는데, 인계 화합물은 연소시 열분해에 의해 폴리인산을 생성하고, 폴리인산이 생성될 때의 탈수작용에 의해 생성되는 탄소피막이 산소를 차단하여 연소를 막는 작용을 하며, 또한 폴리인산 자체로도 보호층의 역할을 하기 때문에 난연제로 이용될 수 있다.As described above, the water-soluble binder composition of the present invention includes a phosphorus monomer and a phosphorus emulsifier. The phosphorus compound generates polyphosphoric acid by thermal decomposition during combustion, and the carbon film formed by dehydration when polyphosphoric acid is produced blocks oxygen. It acts to prevent combustion and can be used as a flame retardant because polyphosphoric acid itself also serves as a protective layer.
특히 본 발명은 다양한 인계 화합물들 중에서도 2-메틸-2-프로펜산 포피니코비스(옥시-2,1-에탄디일)에스터와 같은 인계 모노머를, 폴리옥시에틸렌 트리데실 포스페이트 에스터와 같은 인계 유화제를 이용하여, 아크릴계 모노머와 유화중합하였을 때 생성된 공중합체가 폴리에스터계 안전망의 직교된 부분의 결합을 견고히 할 수 있으며, 바인더 조성물 자체의 난연성 또한 향상시키는 효과가 있음을 발견하였다.In particular, the present invention uses a phosphorus-based monomer such as 2-methyl-2-propenoic acid porphinicobis (oxy-2,1-ethanediyl) ester, among various phosphorus-based compounds, and a phosphorus-based emulsifier such as polyoxyethylene tridecyl phosphate ester. Thus, it was found that the copolymer produced by emulsion polymerization with an acrylic monomer can strengthen the bonding of the orthogonal parts of the polyester safety net, and also has an effect of improving the flame retardancy of the binder composition itself.
다시 말해 본 발명은, 본 발명의 특징적인 물질 조성, 즉 인계 모노머, 인계 유화제를 유화중합에 이용함으로써, PET와 같은 폴리에스터계 안전망과의 상용성이 높아 바인더로서 직물의 직교부위의 결합을 단단히 결속시키는 기능이 있으며, 난연 성능을 향상시키는 기능을 동시에 갖는 새로운 아크릴계 공중합체를 합성하여 이를 코팅 조성물로 포함하는 것을 특징으로 하는 것이다. In other words, the present invention, by using the characteristic material composition of the present invention, that is, a phosphorus monomer and a phosphorus emulsifier for emulsion polymerization, has high compatibility with polyester-based safety nets such as PET, so that the bonding of the orthogonal region of the fabric as a binder is firmly established. It has a function of binding and is characterized by synthesizing a new acrylic copolymer having a function of improving flame retardant performance and including it as a coating composition.
또한, 본 발명은 폴리에스터계 안전망에 난연성을 부여하기 위해 할로겐프리 난연제 조성물을 포함하는데, 상기 할로겐프리 난연제 조성물은 할로겐계 물질(염소, 브롬 등)을 포함하지 않는 친환경 소재의 질소계(구아니딘계) 및 인계 난연제를 구성 성분으로 한다.In addition, the present invention includes a halogen-free flame retardant composition to impart flame retardancy to a polyester safety net, wherein the halogen-free flame retardant composition is a nitrogen-based (guanidine-based) eco-friendly material that does not contain halogen-based materials (chlorine, bromine, etc.) ) and a phosphorus-based flame retardant as components.
일반적으로 다양한 산업분야에서는 할로겐프리(Halogen Free) 규제 사양 및 표준을, 균질 재료 속에 (1) 염소가 900ppm 이하, (2) 브롬이 900 ppm 이하, (3) 염소 및 브롬의 합계 함유율이 1500ppm 이하, (4) 삼산화안티몬이 1000ppm 이하인 것으로 규정하고 있는데, 할로겐계 난연제는 화재시 발생하는 가스의 독성이 문제되기 때문에 환경영향적 측면에서 규제가 강화되고 있는 추세이다. 따라서 본 발명은 친환경적 코팅 조성물을 제공하고자, 할로겐계 난연제를 포함하지 않으면서 난연성을 부여하도록 질소계 및 인계 난연제를 포함하는 것을 특징으로 한다. 특히, 종래 안전망 코팅 조성물에 질소계 난연제를 사용한 사례는 없었다.In general, in various industries, halogen-free regulatory specifications and standards, in homogeneous materials, contain (1) less than 900 ppm of chlorine, (2) less than 900 ppm of bromine, and (3) less than 1500 ppm of chlorine and bromine in total. , (4) antimony trioxide is regulated to be less than 1000ppm, but halogen-based flame retardants are becoming more stringent in terms of environmental impact because the toxicity of gases generated in the event of a fire is a problem. Therefore, the present invention is characterized by including nitrogen-based and phosphorus-based flame retardants to impart flame retardancy without including a halogen-based flame retardant to provide an environmentally friendly coating composition. In particular, there has been no case of using a nitrogen-based flame retardant in a conventional safety net coating composition.
상기 구아니딘계(질소계) 난연제는 설파민산 구아니딘, 인산구아니딘 및 인산 구아닐요소 중에서 선택될 수 있다. 본 발명의 일 실시예에서는, 수용성 바인더 조성물과의 상용성을 고려하여 설파민산 구아니딘을 사용하였다.

In one embodiment of the present invention, amine, C12-14-alkyl, and C6-10-alkyl phosphate, which are environmentally friendly and excellent phosphorus and nitrogen hybrid compounds in consideration of price and flame retardancy, were used at 50% actual solid content.
상기 할로겐프리 난연제 조성물에서 구아니딘계 난연제와 인계 난연제의 비율은 수용성 바인더 조성물과의 상용성, 폴리에스터계 안전망 원단과의 상용성, 난연성 등을 고려하여 적절히 선택될 수 있다. 보다 구체적으로, 상기 할로겐프리 난연제 조성물은 상기 구아니딘계 난연제 50~100 중량부, 상기 인계 난연제 0~50 중량부를 포함할 수 있다. 보다 바람직하게는, 상기 구아니딘계 난연제 70~80 중량부, 상기 인계 난연제 20~30 중량부를 포함한다.In the halogen-free flame retardant composition, the ratio of the guanidine-based flame retardant to the phosphorus-based flame retardant may be appropriately selected in consideration of compatibility with the water-soluble binder composition, compatibility with polyester-based safety net fabric, and flame retardancy. More specifically, the halogen-free flame retardant composition may include 50 to 100 parts by weight of the guanidine-based flame retardant and 0 to 50 parts by weight of the phosphorus-based flame retardant. More preferably, 70 to 80 parts by weight of the guanidine-based flame retardant and 20 to 30 parts by weight of the phosphorus-based flame retardant are included.

상기 수용성 바인더 조성물과 할로겐프리 난연제 조성물의 혼합 비율은 직물의 견직성 및 난연성 향상을 고려하여 적절하게 선택될 수 있다. 보다 구체적으로, 상기 코팅 조성물은 상기 수용성 바인더 조성물 30~80 중량부, 상기 할로겐프리 난연제 조성물 20~70 중량부를 포함할 수 있다. 일 실시예에서는 상기 수용성 바인더 조성물과 상기 할로겐프리 난연제 조성물의 중량비가 70:30 인 것이 바람직하고, 또 다른 실시예에서는, 50:50 인 것이 바람직하다.The mixing ratio of the water-soluble binder composition and the halogen-free flame retardant composition may be appropriately selected in consideration of improving the stiffness and flame retardancy of the fabric. More specifically, the coating composition may include 30 to 80 parts by weight of the water-soluble binder composition and 20 to 70 parts by weight of the halogen-free flame retardant composition. In one embodiment, the weight ratio of the water-soluble binder composition and the halogen-free flame retardant composition is preferably 70:30, and in another embodiment, it is preferable that it is 50:50.
이온성 및 pH를 조절함으로써 상기 수용성 바인더 조성물과 할로겐프리 난연제 조성물의 상용성을 향상시킬 수 있는데, 이때 pH 조절제는 수산화 나트륨, 암모니아수 및 2-아미노-2-메틸-1-프로판올(2-amino-2-methyl-1-propanol) 중에서 선택될 수 있으며, 이는 상기 수용성 바인더 조성물, 아크릴계 공중합체 에멀젼에 추가로 포함될 수 있다. 일 실시예에서는 pH 조절제로서 질소 화합물인 2-아미노-2-메틸-1-프로판올이 첨가될 수 있다. 일 실시예에서는, pH는 8로 조절되는 것이 바람직하며, 이에 따라 상기 pH 조절제의 첨가량은 적절하게 조절될 수 있다. 선택적으로, 상기 pH 조절제는 할로겐프리 난연제 조성물에 포함될 수도 있다.It is possible to improve the compatibility of the water-soluble binder composition and the halogen-free flame retardant composition by adjusting the ionicity and pH. At this time, the pH adjusting agent is sodium hydroxide, ammonia water and 2-amino-2-methyl-1-propanol (2-amino- 2-methyl-1-propanol), which may be further included in the water-soluble binder composition and the acrylic copolymer emulsion. In one embodiment, a nitrogen compound, 2-amino-2-methyl-1-propanol, may be added as a pH adjusting agent. In one embodiment, the pH is preferably adjusted to 8, and accordingly, the addition amount of the pH adjusting agent can be appropriately adjusted.

In particular, the phosphorus-based flame retardant of the present invention is a halogen-free flame retardant and has excellent eco-friendliness, but has low reactivity with conventional PVC resins, making it difficult to use. As a result of the research of the inventor of the present application, it was confirmed that the phosphorus-based flame retardant can be used.

It is understood by those skilled in the art that the same function can be given and it is possible to select from known materials, and the materials may be selected and added in an appropriate ratio in consideration of each function and overall performance of the coating composition.
상기와 같은 조성으로 제조된 본 발명의 코팅 조성물은 수용성 에멀젼, 할로겐프리 난연제, 친환경수지(폴리에스터, 아크릴, 우레탄 등)을 사용하여 독성물질 재료를 대체한 수성 코팅제이기 때문에 유해물질이 없고, 제조 공정 중에도 발생하지 않는다. 따라서 추가적인 옥외 배출시설 등을 필요로 하지 않게 된다.The coating composition of the present invention prepared with the above composition does not have harmful substances because it is a water-based coating agent that replaces toxic materials by using water-soluble emulsion, halogen-free flame retardant, and eco-friendly resin (polyester, acrylic, urethane, etc.). It does not occur during the process. Therefore, an additional outdoor discharge facility is not required.
특히 본 발명의 코팅 조성물은 수성 코팅제이기 때문에 폴리에스터계 원단에 함침 및 고착되는 과정 또한 저온가공(120℃ 이하) 방식으로 제조될 수 있다. 종래 기술에서와 같이 열가소성 수지인 PVC를 코팅 조성물로 포함하는 경우에는, PVC가 녹지 않은 상태로는 원단에 고착이 되지 않기 때문에 이를 원단에 고착시키기 위해서는 PVC의 녹는점 이상의 온도 조건(최소한 160℃ 이상)이 필수적이었다. 이처럼 PVC를 녹여 고착시키는 종래의 고온가공(160℃ 내지 210℃) 방식에서 일반 고강력사를 원사로 이용할 경우 변형, 수축이 심하기 때문에, 원사 또한 수축률이 낮은 저수축사를 사용해야만 했다. 이와는 달리, 본 발명의 코팅 조성물은 수성 코팅제이기 때문에 수분이 증발될 수 있는 온도 조건(약 100-120℃)에서 충분히 가공이 가능한데, 이와 같은 온도 조건에서는 일반적으로 원단 변형, 수축이 잘 일어나지 않기 때문에 일반 고강력사를 원사로 이용할 수 있다. 저수축사는 일반 고강력사에 비해 강도는 낮고(저수축사: 7.8g/데니아, 일반 고강력사: 9g/데니아), 가격이 높기 때문에, 본 발명에서와 같이 일반 고강력사를 사용하게 될 경우 안전망 원단 자체의 강도를 증대시킬 수 있을 뿐만 아니라 원가 절감 효과를 누릴 수 있다.In particular, since the coating composition of the present invention is a water-based coating agent, the process of impregnating and fixing the polyester-based fabric may also be prepared by low-temperature processing (120° C. or less). As in the prior art, when PVC, a thermoplastic resin, is included as a coating composition, since PVC is not adhered to the fabric in an unmelted state, the temperature condition (at least 160 ° C. or more ) was essential. In the conventional high-temperature processing (160 ° C. to 210 ° C.) method of melting and fixing PVC, when using general high-tenacity yarn as a yarn, deformation and shrinkage are severe, so the yarn also had to use a low-shrinkage yarn with a low shrinkage rate. In contrast, since the coating composition of the present invention is a water-based coating agent, it can be sufficiently processed under a temperature condition (about 100-120 ° C) where moisture can evaporate. Ordinary high tenacity yarn can be used as yarn. Low-shrinkage yarn has lower strength than general high-tenacity yarn (low-shrinkage yarn: 7.8g/denier, general high-tenacity yarn: 9g/denier) and is expensive, so when using general high-tenacity yarn as in the present invention, the safety net fabric itself Not only can increase the strength of the product, but also enjoy the effect of cost reduction.
뿐만 아니라, 종래의 고온가공 방식에서는 안전망 원단이 고온에서 변형되지 않도록 물리적으로 고정하는 장치가 필수적으로 필요한데, 이때 고정 장치가 원단의 변부를 잡아 고정해야 하기 때문에 기본 원단의 5%가 폐기물로 발생할 수 밖에 없다. 그러나, 본 발명은 120℃ 이하의 저온에서 열풍을 이용해 본 발명의 코팅 조성물을 원단에 고착시키기 때문에 원단의 변형, 수축을 방지하기 위한 원단 고정장치가 별도로 필요하지 않으며, 따라서 원단 손실이 발생하지 않게 된다.In addition, in the conventional high-temperature processing method, a device for physically fixing the safety net fabric is essential so that it is not deformed at high temperature. there is only However, since the present invention fixes the coating composition of the present invention to the fabric using hot air at a low temperature of 120 ° C. or less, a separate fabric fixing device is not required to prevent deformation and shrinkage of the fabric, and therefore, the fabric is not lost. do.
이처럼 저온가공 방식을 채택함으로써 원가절감, 원단손실 방지, 원단 강도 향상 등의 효과가 있으면서 동시에 전기 에너지 사용을 기존대비 70% 정도 줄여 저탄소 녹색 생산이 가능하게 된다. 다시 말해, 가공 온도를 낮출 수 있어 텐타설비(고온)과 같은 설비를 필요로 하지 않기 때문에, 에너지 사용을 현저히 저감시킬 수 있으며 온실가스(CO2) 발생 저감 효과가 있다.By adopting such a low-temperature processing method, there are effects such as cost reduction, fabric loss prevention, fabric strength improvement, and at the same time, electric energy consumption is reduced by 70% compared to the existing method, enabling low-carbon green production. In other words, since the processing temperature can be lowered and no equipment such as tenter equipment (high temperature) is required, energy consumption can be significantly reduced and greenhouse gas (CO 2 ) emission reduction effect is achieved.
또한 본 발명의 코팅 조성물로 코팅된 안전망은 종래 기술과 비교하여 경량화가 가능하다. 종래 기술과 같이 PVC를 코팅 조성물로 포함하는 경우, PVC는 물에 잘 녹지 않기 때문에 코팅 조성물을 전체적으로 유기성의 물질들로 제조해야만 한다. 이때 사용되는 유기용제들은 증발되면서 환경오염 물질을 생성하게 된다. 뿐만 아니라 PVC가 유기용제에 잘 녹을 수 있도록 추가 첨가제를 필요로 하는데, 이렇게 제조된 코팅 조성물은 본 발명의 수성 코팅 조성물과 비교하였을 때 점도가 높아, 원단에 함침시켰을 때 과도한 양의 코팅 조성물이 불필요하게 원단에 묻어 잔류되게 되고, 따라서 안전망 직물 자체의 중량이 불필요하게 증가될 뿐만 아니라 제조 공정 중에도 코팅 조성물이 낭비되게 된다. 그러나 본 발명의 수성 코팅 조성물은 수성으로서 점도가 낮기 때문에 과도하고 불필요하게 원단에 잔류하지 않아 PVC 코팅 조성물과 비교하였을 때 가공 가능한 원단 면적을 증대시킬 수 있으며, 수분이 증발된 후의 안전망 직물지는 종래의 PVC 코팅 조성물을 이용한 것과 비교하였을 때 중량이 낮아지는 효과가 있다. 보다 구체적으로, 종래 기술과 같이 PET 안전망에 PVC를 코팅하는 경우에는 제조된 안전망의 중량이 300 g/㎡ 이상이나, 본 발명의 코팅 조성물로 코팅하는 경우에는 220~250 g/㎡ 정도이기 때문에 기존 기술 대비 20% 이상 경량화가 가능하여 안전망 설치시 작업효율을 향상시킬 수 있으며, 앞서 설명한 바와 같이 가공 가능한 원단의 면적 또한 증대시켜 자원 이용 효율을 향상시킬 수 있다.In addition, the safety net coated with the coating composition of the present invention can be reduced in weight compared to the prior art. When PVC is included in the coating composition as in the prior art, since PVC is poorly soluble in water, the coating composition must be entirely made of organic materials. The organic solvents used at this time evaporate and generate environmental pollutants. In addition, additional additives are required so that PVC can dissolve well in organic solvents, and the coating composition prepared in this way has a high viscosity compared to the aqueous coating composition of the present invention, so that an excessive amount of the coating composition is unnecessary when impregnated into a fabric. Thus, the weight of the safety net fabric itself is unnecessarily increased and the coating composition is wasted during the manufacturing process. However, since the water-based coating composition of the present invention is water-based and has a low viscosity, it does not excessively and unnecessarily remain on the fabric, thereby increasing the area of the fabric that can be processed compared to the PVC coating composition. There is an effect of lowering the weight when compared to using a PVC coating composition. More specifically, in the case of coating PVC on the PET safety net as in the prior art, the weight of the manufactured safety net is 300 g/m2 or more, but in the case of coating with the coating composition of the present invention, it is about 220 to 250 g/m2. It is possible to reduce the weight by more than 20% compared to the technology, so the work efficiency can be improved when installing the safety net.
