Do FR-V6 flame retardant standard environmental protection, fire protection needs to collaborate
Edit: Taizhou New Material Co., Ltd.Date: 2016-07-02

Today, plastic, rubber, chemical fiber, paint and other polymer materials are increasingly filled with people's lives. Polymer materials to bring light, efficient and other advantages, but also for people's lives buried safety risks. Long carbon chain of polymer materials in the heat will be broken down into small molecules flammable, easily lead to fire. How to avoid the safety risks, so that the polymer material to better serve people's daily life? This requires the addition of FR-V6 flame retardants to the material according to the relevant standards.

The main role of FR-V6 flame retardants is to slow down the time when the polymer burns or decomposes, extending people's escape time in a fire. Proper use of flame retardants can be described as significant, but some enterprises in the production and construction process, for cost and other reasons, not in accordance with the standard to add flame retardants, and even simply do not use flame retardants, and ultimately lead to disaster.

In 2009, CCTV TCEP manufacturers new building was splashed fireworks ignition, the fire instantly spread, a full 6 hours of burning, resulting in direct economic losses of 163.83 million yuan. The survey results show that this fire is due to flame retardant material selection due to substandard. The building curtain wall construction side should use flame retardant grade B1 (flame retardant) extruded polystyrene insulation board, but the purchase of the combustion is not up to B2 (combustible) extruded board.

Coincidentally, 2010 Shanghai Jing'an District teacher apartment fire is also because the wall insulation layer is not required to choose a flame retardant properties of the material, but illegal use of a large number of polyurethane foam and other highly explosive materials, and ultimately lead to 58 people were killed in the disaster.

Two fires exposed the lack of fire control in China. It is understood that China's fire-retardant legislation is still in its infancy, the standard imperfect and safety supervision measures are not so that different industries are facing fire hazards. China Fire-retardant Society Secretary-General Zhou Zhengmao pointed out that China should speed up the revision of the relevant fire-retardant products and the establishment of third-party testing organizations to further improve the relevant laws and regulations, strengthen supervision, so that flame retardant materials play a fire retardant role.

It is reported that in 2015, Shenzhen Airlines occurred arson case, it is precisely because the aircraft seat in strict accordance with the standard fire-retardant manufacturing, and ultimately to avoid a tragedy. Afterwards, an airline captain Zhang Peng said in an interview with reporters, the aircraft floor, seats, doors, are made of high flame-retardant properties of the material, will not be easily ignited, the possibility of fire is not ; Even if the local fire, can also be used in the cabin fire extinguisher in time to extinguish.

In addition to standards and regulatory issues, the flame retardant industry is also facing a major controversy in environmental protection: halogen or halogen-free? After hexabromocyclododecane is defined as persistent organic pollutants are banned, many unknown people believe that halogen-containing flame retardants have irreversible pollution and toxicity to the environment and the human body. Many environmental groups also hold high the banner of halogen-free, requiring bromine products permanently quit the "rivers and lakes."

The halogen-free movement has shrunk the market for brominated flame retardants. An industry source told reporters that in 2004 halogen-free flame retardant aluminum hydroxide production is 2,000 tons, and by 2015, production has soared to 100,000 tons. "Preemption is of course the market for brominated flame retardants."

"Blind pursuit of halogen-free, which is unwise choice," Chinese fire-retardant Institute Secretary-General Zhou Zhengmao said that different types of flame retardants have their own different advantages, enterprises should be selected in accordance with the specific application areas for scientific judgment. To electric vehicles, for example, the car at the moment the great current, the flame retardant requirements of the circuit board is very high, only bromine flame retardants can meet the requirements of the components on the flame retardant performance, blind pursuit of halogen-free Significant security risks.

Bromine Environment and Science Forum, Dr. Han Songqing believes that bromine flame retardant pollution itself is a false proposition. "It is absurd to judge whether a class of products is contaminated by the presence of certain elements, and Han Chuangqing points out that the scientific judgment on toxicity and pollution must be directed to a particular substance, from its chemical structure itself Analyze whether the substance is persistent, bioaccumulative and toxic substances (PBT), whether it is carcinogenic, mutagenic, and reproductive toxic substances (CMR).

According to the introduction, the EU's REACH regulations, the United States "toxic substances control bill" and other regulatory regulations do not have any provisions on brominated flame retardants to a comprehensive limit or prohibit, is now producing and using more than 70 kinds of brominated flame retardant , Only polybrominated biphenyls and polybrominated diphenyl ethers are no longer used, hexabromocyclododecane is defined as persistent organic pollutants. Other brominated flame retardants have been identified as non-PBT, non-MCR, continue in the automotive, construction, electronic products and other areas play light and heat. "The need to point out that", Han Songqing stressed that hexabromocyclododecane was banned after the European Union, the US Environmental Protection Agency (EPA) and the Japanese Ministry of Economy, Trade and Industry (METI) recommended or approved several hexabromocyclo Alkane alternatives are still brominated flame retardants.
