이 발명은 난연시트 및 그 제조방법에 관한 것이다. 자세히 이 발명은 난연성 탄성 복합체인 난연시트를 제공하며, 난연시트에 의한 방진,방호용 두건을 제공한다. 이 발명 난연시트는 두건 외에도 화재로부터 개인을 보호하는 산소발생마스크, 방독면을 포함하는 개인용 안전용구, 구명 용구 등의 재료로 사용된다.The present invention relates to a flame retardant sheet and a method of manufacturing the same. The present invention provides a flame retardant sheet is a flame retardant elastic composite, and provides a hood for dustproof and protective by the flame retardant sheet. The flame retardant sheet of the present invention is used as a material such as an oxygen generating mask that protects an individual from a fire, a personal safety device including a gas mask, and a life preserver in addition to a hood.
종래의 화재 및 가스누출 재해 등에 사용되는 개인 안전용구인 두건의 재료는 천연섬유 또는 합성섬유 직물에 액상고무, 고무풀, 혹은 열가소성 수지, TPE(Thermoplastics elastomer) 등을 코팅하거나 압연한 시트로 제조되었다. 이와 같은 종래의 난연성 시트는 난연성 약하고 높은 코스트가 문제이다. 액상고무 및 고무풀을 직물 위에 입하는 난연가공은 직물에 다층 코팅층을 적층하는 복잡한 공정이 코스트 업의 주 원인이다. 열가소성 수지 및 TPE 코팅 직물은 요구되는 난연성을 충족하지 못하고 있다.The hood material, which is a personal safety device used in a conventional fire and gas leakage disaster, is made of a sheet coated or rolled with natural rubber or synthetic fabric fabric with liquid rubber, rubber paste, thermoplastic resin, TPE (Thermoplastics elastomer), or the like. Such a conventional flame retardant sheet is problematic in flame retardancy and high cost. In flame retardant processing, in which liquid rubber and rubber glue are applied onto a fabric, a complicated process of laminating a multilayer coating layer on the fabric is a major cause of cost up. Thermoplastic and TPE coated fabrics do not meet the required flame retardancy.

The present invention seeks to provide a flame retardant sheet manufacturing method which is easy to manufacture and can be manufactured at low cost. The present invention is to provide a flame retardant sheet which is heated to form a carbonized layer and the flame retardant effect is obtained by preventing the movement of the flame. The present invention seeks to provide a flame retardant sheet that satisfies UL standards and FMVSS302, regardless of the type of polymer that is the base of the flame retardant compounded rubber. The present invention aims to provide a hood as a flame retardant sheet and a personal safety device having excellent flame retardancy that can faithfully protect an individual in a flame scene.
이 발명은 고상 고무를 난연 배합고무로 콤파운딩 한 후 캘린더(carlender)에서 기층 섬유에 얇게 입히고(friction) 난연 배합고무층과 기층 직물을 가교 접착시키는 공정을 채용하여, 코스트 다운과 안정한 고 품질 난연시트를 얻고 이 난연 시트로 개인 보호장비의 필수조건인 난연성을 UL94의 V0등급과 ASTM E162, ASTM E662, ASTM C1166 , SMP-800-C에 적합하게 하였다.The present invention employs a process of compounding solid rubber into a flame retardant compounded rubber, and then applying a process of thinly coating the base fiber in a calender and crosslinking the flame retardant compounded rubber layer and the base fabric to reduce cost and stabilize high quality flame retardant sheet. This flame retardant sheet was designed to meet the requirements of UL94 V0 and ASTM E162, ASTM E662, ASTM C1166 and SMP-800-C.
이 발명은 매우 우수한 난연성으로 인하여 개인 안전용구 두건 외에도 난연 시트로서 많은 분야에서 이용될 수 있다.This invention can be used in many fields as a flame retardant sheet in addition to a personal safety hood due to its very good flame retardancy.
이 발명 탄성 복합체인 난연시트는 천연직물, 합성섬유직물 및 부직포를 포함하는 기층 직물에 난연 배합고무를 입히고 열과 압력을 가하여 직물과 난연 배합고무를 가교접착 시켜 제조한다. 이 발명은 난연제의 조성 및 난연 배합고무의 설계 및 제조가 중심이 된다. 난연 배합고무는 기층 직물과 가교 접착되어 고온에서 난연성을 유지하면서 안정한 접착 상태를 지켜야 하므로 난연 배합고무의 자착력, 표면성분(표면장력)이 난연 배합고무의 설계에 중요한 요소로 관계된다. 난연 배합고무를 섬유 기층 직물에 입히는 과정의 선택도 중요하다. 섬유직물들은 난연 시트의 기층 재료로서 직물 자체의 인장 강도나 유연성이 이 발명 기층재료의 요건을 대체로 충족하고 있다. 기층 직물의 섬유가 난연처리된 것이라면 더욱 좋겠으나 가격을 고려하면 난연처리 섬유는 이 발명에서 꼭 필요한 것은 아니다. Flame retardant sheet is an elastic composite of the present invention is prepared by applying a flame-retardant compounding rubber to the base fabric including natural fabrics, synthetic fiber fabrics and non-woven fabrics and applying heat and pressure to cross-link the fabric and the flame-retardant compounding rubber. This invention centers on the composition of a flame retardant, and the design and manufacture of a flame retardant compounding rubber. The flame retardant compounded rubber is cross-linked with the base fabric to maintain a stable adhesive state while maintaining flame retardancy at high temperature, so the self-adhesion and surface components (surface tension) of the flame retardant compounded rubber are important factors in the design of the flame retardant compounded rubber. The choice of the process of applying flame retardant rubber to textile based fabrics is also important. Textile fabrics are the base material of flame retardant sheets, and the tensile strength or flexibility of the fabric itself generally meets the requirements of this base material. It would be better if the fibers of the base fabric were flame retardant, but considering the price, the flame retardant fibers are not necessary in this invention.
이 발명 난연시트를 제조하기 위하여 먼저 기층 직물을 선택하고, 난연 배합고무를 제조하고 기층직물에 난연 배합고무를 0.08-3mm 두께로 입히고, 직물과 난연층을 가교 접착시킨다. 이 발명은 이와 같이 제조된 난연 시트는 개인 안전용구의 구조와 형태에 따라 재단하고 재봉하여 두건을 포함하는 개인 안전용구를 제조한다. In order to manufacture the flame retardant sheet of the present invention, first, a base fabric is selected, a flame retardant compounded rubber is prepared, a flame retardant compounded rubber is coated on the base fabric to a thickness of 0.08-3 mm, and the fabric and the flame retardant layer are cross-linked. The present invention is a flame-retardant sheet prepared in this way to cut and sew according to the structure and form of personal safety equipment to produce a personal safety equipment including a hood.

The base polymer of the flame retardant compounded rubber can use both synthetic rubber and natural rubber. Chloroprene rubber (CR, Chloroprene), chlorosulfonylated polyethylene (Chlorosulphoneized polyethylene), chloropolyethylene (CPE, chloropolyethylene), NBR-PVC, etc. are preferable, and ordinary synthetic rubber can also be used. If natural rubber is used, it is necessary to use a large amount of flame retardant fillers and pay attention to weather resistance.
