: August 12, 2015, Tianjin Port Ruihai company explosion shocked the whole of China, the second explosion equivalent to 24 tons of TNT equivalent of the fact is even more impressive. According to the latest data, the August 12 bombings in Tianjin have killed 114 people and left 65 unaffemented.
18, the seventh day of the tianjin port explosion in China, according to China's traditional customs, is the unfortunate victims of the "first seven" festival day. At 9 a.m., seven sites in Tianjin held a collective silence to mourn the victims, and ships in Tianjin Port sounded their sirens for three minutes to pay tribute to the victims.
in the heavy sorrow, chemical production enterprises should be sad, from the explosion to learn lessons and inspiration, strengthen the importance of production safety issues.
, the building for fire prevention role is also worthy of enterprises to ponder a problem. In recent years, there have been many major fire accidents caused by the insulation materials of the exterior walls of construction projects throughout the country, which have exposed many new situations and problems in the field of fire control of the exterior wall insulation system and decorative materials of civil buildings. Therefore
coatings
industry as an industry related to the decoration of building facades, enterprise research and development and production of
awall coatings
products have the functionality of consumer concern.
the 80's, China's tiles developed rapidly, meeting people's decorative requirements for the facade of the building. However, because the exterior tiles are prone to a wide range of falling and injuring accidents, from 2000 onwards, the provinces of the country have introduced relevant regulations: prohibit the use of external wall tiles in high-rise buildings or crowded places, while promoting the application of high-performance, environmentally friendly exterior paint. Since then, colorful, multi-functional, to meet the different needs of consumers of exterior paint has become an important choice for people.
, thermal insulation coatings because of the building can play a role in warm winter and cool summer, has been favored by many consumers. It is understood that at present, China's buildings use more organic insulation materials are polystyrene and polyurethane hard foam materials, their biggest advantage is light quality, insulation and good insulation effect, the biggest defect is poor fire resistance, easy aging and combustion.
from a certain point of view, there is a certain contradiction between the performance of exterior paint insoofing and fire prevention. Organic insulation materials have good insulation, but poor fire protection. Inorance insulation material fire resistance is good, but insulation performance is poor. Therefore, if the building facade chooses to use organic materials with good insulation, it will increase the risk of causing fires and accelerating the spread of fires.
May 25 this year, 38 people were killed and six injured in a fire at Kang paradise old-age apartment in Lushan County, Pingdingshan City, Henan Province. The accident exposed the production and operation units illegal use of flammable combustible materials as core materials of colored steel plate building fire resistance level is low and other issues. On August 5th, a clear picture of the exterior wall of a new house on the first floor of the Taiyuan Riverside in Shanxi province was exposed and again caused panic among the whole population.
the use of insulation paint building fire frequently, again and again affect the nerves of the organic insulation industry. On the one hand, building energy conservation is the trend, the market demand for organic insulation materials is growing, on the other hand, the fire safety situation is becoming more and more serious. How to coordinate the contradiction between building energy saving and fire safety has become an urgent problem in front of government management departments, construction industry and insulation materials industry.

to promote building energy conservation imminent insulation fire prevention can both?
years, China is facing severe pressure of energy conservation and emission reduction, building energy conservation has increasingly attracted the attention of all sectors of society. According to the relevant data, China's building energy consumption accounts for about 30% of the total energy consumption of the whole society, in high-energy buildings, the wall and exterior window thermal loss accounted for 85% of the total heat loss of buildings.
Therefore, in order to achieve energy saving in the building, it is necessary to improve the insulation performance of the exterior wall, in the field of building insulation, polystyrene, polyurethane foam and other organic materials have inorganic materials can not be compared with the advantages, including high insulation performance, easy construction and so on. However, polystyrene and polyurethane foams themselves have flammable properties and must be added flame retardants to achieve the corresponding flame retardant level.
flame retardant in the combustion process by playing the following roles to achieve flame retardant: (1) capture free-form; At present, some organic insulation coatings in China's market have been retardant treatment, trying to improve the flame retardant properties of materials, and thus reduce the possibility of fire risk.
some people may think that the insulation material with flame retardants after the fire protection function, in fact, "flame retardant" and "fireproof" is not the same thing. The flame retardant of material refers to the fire retardant object after being treated by special method, the object itself has the performance of preventing, slowing down or terminating combustion, the object of flame retardant is the material itself, and the fire resistance of the object is destroyed by some way, so that the combustible object does not heat up quickly when attacked by fire, and the object of fire protection is the object that needs to be protected.
the principles of "flame retardant" and "fire prevention" are different, but in the event of a fire, we can control the fire to a certain extent, so that people flee the scene and firefighters to fight the fire to get enough time.
application of fire retardant materials is the most important technical means to ensure fire safety, which can play the role of source control.
" if strictly in accordance with the requirements of the specifications, product compliance, construction is legal, the building of malignant fire accidents can be completely avoided, the current domestic flame retardant technology and products at the technical level is completely free of problems. "However, most of the materials on the market have not been subject to the corresponding flame retardant treatment, and the flame retardant properties simply do not meet the flame retardant standards required by building fire safety regulations. It
understood that compared to non-flame retardant materials, the price of flame retardant materials is 10%-30% higher, the high price is difficult for enterprises to accept. Some developers in order to save costs at the expense of unethical use of inferior materials, so that a large number of poor quality, unqualified flame retardant materials flooded the market, to the building brought great hidden dangers, but also buried around people "time bomb."
As early as 2011, the provincial public security departments, housing and urban and rural construction departments jointly issued a notice, in the province-wide focus on building exterior insulation materials fire safety special rectification, and constantly strengthen the quality supervision of civil building exterior wall insulation materials, and strive to maximize the containment of civil building fire accidents.
In the Interim Regulations on Insulation Systems and Exterior Wall Decoration fire prevention issued by the Ministry of Public Security, Housing and Urban-Rural Development, clear requirements are put forward for the combustion properties of insulation materials used in different buildings. The Interim Provisions require that the combustion performance of insulation materials outside civil buildings should be A-grade and should not be lower than B2.
in the combustion properties of insulation materials outside civil buildings, only A-grade is non-combustible materials, throughout the market, to achieve this requirement of a few materials. Class B materials are divided into three levels, B1 is flammable, B2 is flammable, B3 is flammable. This means that the building's minimum requirements must be at least until the hard-to-burn B2 level meets the standard.
In order to reduce the occurrence of building fire accidents, relevant government departments should strictly limit the production and application of insulation materials for flammable organic buildings, modify and improve relevant technical specifications, strengthen the supervision and inspection of
