The present invention relates to an FRP reinforcing bar with enhanced flame retardancy and adhesive strength, and an apparatus for manufacturing the same. The FRP reinforcing bar includes a flame-retardant aqueous solution, a reinforcing fiber, a surface protective film, and an adhesive strength increasing material. Also, the FRP reinforcing bar includes a fiber support and resin impregnated box, a surface protector, a first dryer, a molding machine, a coating machine, an attaching machine, a second dryer, a cooler, a drawing machine, a cutting machine, and a trimming machine. According to the present invention, the FRP reinforcing bar can prevent secondary damage from fire by blocking movement of flame in advance with the flame-retardant performance given when exposed to fire. When used as a substitute for reinforcing bars in structures such as concrete, adhesion is enhanced and durability is improved. In addition, by improving a method of tying reinforcing fiber yarns when manufacturing FRP reinforcing bars, there is an effect of improving the continuity of a manufacturing process, space reduction of molding equipment, and maintenance.

Description

난연성과 부착력이 강화된 FRP 보강근 및 그 제조장치{FRP reinforcing bar with enhanced non-flammability and adhesion, and device for manufacturing the same}FRP reinforcing bar with enhanced non-flammability and adhesion, and device for manufacturing the same

본 발명은 난연성과 부착력이 강화된 FRP(Fiber Reinforced Plastics : 섬유강화 플라스틱) 보강근 및 그 제조장치에 관한 것으로서, 더욱 상세하게는 난연성능을 구현하는 성분으로 사용되는 무기계 광물의 분말 및 세골재와 유기계 분말을 FRP 보강근 제조공정 단계에서부터 포함시킴으로써 FRP 보강근에 반영구적인 난연특성이 부여되고, 콘크리트와 같은 구조물 속에 철근 대용으로 사용 시 난연재료의 거친표면 형상과 콘크리트와의 부착력 강화로 내구성이 향상되는 FRP 보강근을 보다 효율적으로 생산할 수 있는 난연성과 부착력이 강화된 FRP 보강근 및 그 제조장치에 관한 것이다.The present invention relates to a FRP (Fiber Reinforced Plastics) reinforcing bar with enhanced flame retardancy and adhesion and an apparatus for manufacturing the same, and more particularly, inorganic mineral powder, fine aggregate, and organic powder used as a component for implementing flame retardant performance. FRP reinforcing bars are given semi-permanent flame retardant properties by including FRP rebar from the manufacturing process stage, and when used as a substitute for rebar in structures such as concrete, FRP reinforcing bars with improved durability due to the rough surface shape of flame retardant materials and reinforcement of adhesion to concrete It relates to an FRP reinforcing bar with enhanced flame retardancy and adhesion that can be produced more efficiently and a manufacturing apparatus therefor.

일반적으로 난연성 섬유강화 플라스틱(FRP)을 제조하는 방법에서 사용되는 수지는 메틸올기를 포함하는 열경화성 수지의 형태로 시판되고 있는데, 이러한 메틸올기를 포함하는 열경화성 수지는 페놀 수지나 멜라민 수지를 포름알데히드에 적정비율로 반응시켜 제조된다.In general, the resin used in the method of manufacturing a flame-retardant fiber-reinforced plastic (FRP) is marketed in the form of a thermosetting resin containing a methylol group. It is prepared by reacting in an appropriate ratio.

시판되는 메틸올기를 포함하는 열경화성 수지는 120~180℃ 에서 10~45kgf/cm2 의 압력 이상으로 가압함으로써 성형이 가능하며, 생활용품으로는 펄프, 셀룰로우즈 등을 필러로 하여 그릇이나 화장판 또는 PCB 기판 등의 성형에 사용되고, 건축용으로는 유리섬유(Glass fiber), 화강암 섬유(Basalt Fiber), 탄소섬유(Carbon fiber), 규소섬유(Silica fiber), 아라미드 섬유(Aramid fiber), 보론섬유(Boron fiber), 나일론계 섬유(Nylon-based fiber)를 주재료로하여 사용하고 있다.Commercially available thermosetting resins containing methylol groups can be molded by pressing at a pressure of 10 to 45 kgf/cm 2 or more at 120 to 180° C. Or used for molding PCB boards, etc., for construction, glass fiber, granite fiber, carbon fiber, silicon fiber, aramid fiber, boron fiber ( Boron fiber) and nylon-based fiber are used as main materials.

이러한 수지를 난연화하기 위해 일반적으로 사용되는 난연재는 크게 할로겐이나인 또는 아민류를 포함하는 유기계 난연재와 무기질을 주성분으로 하는 무기계 난연재로 나뉘며 기존의 방법에 사용되는 난연재료로는 국내 여러특허에 공개된 무기계 암모늄 포스페이트 및 실리카, 알루미나, 구아니딘, 탄산수소나트륨, 석고, 산화 알루미늄, 탄산칼슘, 산화규소, 산화마그네슘, 염화마그네슘 등이 적정비율로 제조되어 생활용품 및 건설자재로 사용되고 있으나, 국가기술표준원의 시험기준(KS M 3015 : 2003(A법))인 내연성 시험에서 난연성 판정이나 국토해양부고시(제2009-866호)의 "건축물 내부마감재료의 난연성능 기준" 의 기준을 상회하는 예는 없었으며 특히, FRP 보강근과 같이 건설부분에서 사용되는 자재의 난연기능이 포함되는 제품은 없었다.Flame retardants generally used to flame retardant such resins are largely divided into organic flame retardants containing halogens or phosphorus or amines and inorganic flame retardants containing inorganic substances as a main component. Inorganic ammonium phosphate, silica, alumina, guanidine, sodium bicarbonate, gypsum, aluminum oxide, calcium carbonate, silicon oxide, magnesium oxide, magnesium chloride, etc. are manufactured in appropriate proportions and are used as household goods and construction materials. In the flame retardancy test, which is the test standard (KS M 3015: 2003 (Method A)), there was no case that exceeded the standard of "flammability performance standards for interior finishing materials for buildings" of the Ministry of Land, Transport and Maritime Affairs Notice (No. 2009-866). In particular, there was no product that included the flame retardant function of materials used in construction, such as FRP reinforcing bars.

또한, FRP 보강근 제조 시 다수개의 섬유(원사)를 하나로 묶는(Braiding) 단계, 수지를 함침하는 단계, 1차 열경화 처리단계, 가압하여 성형하는 단계, 2차 열경화 처리단계, 냉각단계, 절단 및 포장단계 중 묶는(Braiding) 단계에서 묶는 실이 소진될 때 새로운 것으로 교체하는 동안 전체 공정을 일시 중지해야 하는 번거로움과 가압하여 성형하는 장비가 복잡하여 유지관리에 어려움이 있었다.In addition, when manufacturing FRP reinforcing bars, a step of braiding a plurality of fibers (yarns) into one, a step of impregnating a resin, a first heat curing treatment step, a pressing and molding step, a second heat curing treatment step, a cooling step, cutting And when the yarn to be tied in the braiding step of the packaging step is exhausted, the entire process has to be paused while replacing it with a new one, and the equipment for pressing and molding is complicated, making it difficult to maintain.
