Development of flame retarding organic materials and application technology
 
 

Project Leader: Cho, Nam-Wook (Research Fellow, nwcho@kict.re.kr)

 

 
KITC’s Fire Investigation, Research, Testing, and Education conducts a material development project to meet the two goals of the government ministry: “reinforcing fire safety standards“, and “strengthening the energy standards of buildings in order to cope with climate change”.
 
Accordingly, we have developed various flame retardant organic materials and have been conducting various studies using these materials.
 
As a result, we developed “semi-fireproof organic insulation” based on Ministry of Land, Transport and Maritime Affairs notification by reacting flame retardant additive to organic insulation material and also developed “semi-fireproof plastic material” which kept molding performance while suppressing flame, smoke and toxic gas generation. Organic materials with flame retarding function can be applied to finishing materials, insulation materials and composite panels in the field of construction that has strengthened fire safety system. And it can be applied to civil engineering, shipbuilding, aviation and railway as well.
 
 
 
■ Research background
 
Under the Paris Climate Change Agreement of December 2015, Korea has implemented policies to reduce greenhouse gas emissions with strengthened energy policies in the construction sector. The passive house design in 2017 aims to reduce energy consumption by 60% compared to the existing one. In 2025 the zero energy building is expected to become mandatory. Meanwhile, fire safety standards have been strengthened along with stricter energy standards. The overall safety standards for buildings have become more rigid in accordance with the “Comprehensive Measures to Strengthen Building Safety” since the Sewol ferry sinking disaster. In January, 2016, the construction act strengthening the fire resistance performance criteria of exterior finishing materials and insulation materials was revised after a fire accident in Uijeongbu apartment.
 
In response to meet the two purposes of strengthened energy standards resulting from climate change and strengthened fire safety standards, the development of new materials has emerged as a difficult technology for SMEs, and the KICT has carried out various material development researches to satisfy these goals.

■ Research content
 
The KICT developed the material technology of semi-fireproof organic insulation and semi-fireproof plastic as two items of flame retardant organic materials. It developed organic flame retardant material technology and relevant process technology to produce it, and evaluated performance through fire tests of various sizes.
 
• Development of semi-inflammable organic insulation based on phenolform, development of catalysts and hardeners for insulating materials, and development of quasi-incombustible plastics
• Development of process technology: development of insulation (production of core material prototype for fire door based on 7 steps of continuous automation process technology) / development of plastics (implementation of special process technology automation pilot, and manufacturing of lightweight plastic door for fire doors, aluminum composite panel, and exothermic panel prototype)
• Fire test to ensure good performance: Fire retardant performance evaluation (con-calorimeter, gas hazard/ secured externally accredited institutional testing performance), Fireproof door fire resistance test(40-minute thermal performance / 30 minutes as standard)

■ Research achievement
 
We have developed flame-retardant organic materials to respond to strengthened energy performance standards of buildings and strict fire safety standards of buildings and have developed derivative technologies using them. To accomplish these goals, the KICT has established a patent portfolio for core element technology and have won various contests thanks to technology transfer and excellent research by acquiring many industrial property rights, practical research.
 
• Establishment of non-flammable plastic patent portfolio and technology transfer
   - Established a portfolio of flame retardant plastic technology: 26 cases of family patents (17 registered ones)
   - Achievement through transfer of flame retardant material technology: Transfer of material original technology and its application technology (15 cases)
 
• Establishment of mass production test-bed and patent portfolio of semi-fireproof insulation materials/ plastics
   - Material source technology for semi-fire-proof resin manufacturing method Patent and technology transfer 1 case
   - 4 detail patents on the processing element technology that is constructed with regard to the manufacturing methods
   - 13 patent application cases for quasi-fireproof insulation / plastic applied product technology
 
• Grand prize at the Korea-US Patent Competition (2013)
 
• Awarded the Jang Young Sil Award for the achievement of the development of flame retardant materials (2016)
 
• Awarded the award of the Commissioner of the Korean Intellectual Property Office as the outstanding example of research note writing (2016)

■ Expected Effects
 
It is possible to solve the technical difficulties of small companies through the transfer of technology by developing organic material safe for fire. In particular, this study has established a strong patent portfolio based on the source material technology, and it is easy to develop applied material technology and verified the performance through various fire performance experiments.
 
Currently, the KICT applied researches to fire doors, shipbuilding, modular houses, mobile houses, etc., and manufactured prototypes and its mass production was confirmed. Especially mobile houses using semi-fireproof organic materials have been built and being used as a test-bed.
 
The scope of R&D will continue to be broadened by securing source technologies necessary for responding to climate change and reinforcing fire safety as well as developing applied technologies. The results of this research is expected to contribute to the fire safety of society as a whole, being used as an efficient energy building system for the safe land development.
