Abstract:
본 발명은 폴리우레탄폼용 인계 난연제 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 할로겐원소를 배제하고 분자내에 2 ~ 6개의 인원자, 및 질소원자를 함유하는 인계 난연제 및 이의 제조방법에 관한 것이다. 본 발명에 따른 인계 난연제는 폴리우레탄폼에 적용시 폴리우레탄폼의 난연성을 향상시키면서도 시간경과에 따른 용출현상이 없어 난연성 저하 현상을 발생시키지 않으며, 또한 폴리우레탄폼의 기계적 물성을 저하시키지 않으므로 기존의 할로겐계 난연제를 친환경적 난연제로 대체할 수 있다.
Abstract:
PURPOSE: A phosphorous-based flame retardant for polyurethane foam is provided to obtain excellent flame retardance without degradation of mechanical properties, and to have excellent flame retardance comparison to existing halogen-containing flame retardants. CONSTITUTION: A phosphorous-based flame retardant for polyurethane foam is in chemical formula 1. In chemical formula 1, n is an integer from 1-5. R1 is a C2-8 alkylene group, or a C6-7 arylene group. R2 is NHCONH2. A manufacturing method of the phosphate flame retardant comprises: a step of manufacturing an intermediate product by reacting polyphosphoric acid and diol; and a step of manufacturing the phosphorous-based flame retardant by reacting the intermediate product and urea. The polyphosphoric acid comprises 2-6 phosphorous atoms per one molecule.

CONSTITUTION: A TPO sheet composition comprises 35~45 weight% of partially crosslinked thermoplastic olefin resin, 5~15 weight% of non-crosslinked thermoplastic olefin resin, 10~20 weight% of polypropylene resin, 10~20 weight% of ethylene octene rubber, 10~20 weight% of linear low-density polyethylene resin and 5~10 weight% of inorganic filler. The partially crosslinked thermoplastic olefin resin has a hardness of Shore A 65.
Abstract:
PURPOSE: A modifier for a reactive hot melt adhesive, and the reactive hot melt adhesive including thereof are provided to secure the initial adhesive force and the coherence strength between non-polar materials, and to prevent the generation of volatile organic compounds. CONSTITUTION: A modifier for a reactive hot melt adhesive contains a multi-block copolymer. The multi-block copolymer is obtained by polymerizing a polymer initiator having a hydrophilic segment formed by condense-polymerizing a hydrophilic polymer and 4,4`-azobis(4-cyanopentanoic acid), layered silicate, a vinyl monomer, and a chain transfer agent.
