Aluminum Foil Aerogel Blanket in Vehicle Insulation Fire Protection Applications
Modified High Thermal Barrier Thermal Insulation Applications in Vehicles - The Only Flame-Retardant Thermal Insulation to Meet the Latest Passenger Safety Standards
Background introduction
China's automobile industry has made remarkable achievements in the world, and transportation tools have become one of the most closely related facilities to people's lives. From 2010 to 2014, China's annual average passenger car output reached 2.32 million, ranking the highest in the world. However, the frequency and extent of loss of passenger safety accidents are equally fierce.
Shown above is the bus accident. Accident vehicle body flammable polyurethane insulation, car insulation laying at the end of the same flammable foam. According to the survey, the vast majority of vehicle interior insulation is still flammable combustible organic foam insulation material. In the event of a fire, traditional organic insulation material can easily be ignited, thereby contributing to the fire, expanding the disaster and generating a large amount of poisonous gas, directly endangering the respiratory and nervous systems of passengers, making it difficult for passengers to escape. So we see that every time a bus fire is a shocking heavy casualties.
Therefore, the vehicle manufacturers, operating units and government regulatory departments are urgently needed a fire retardant and highly efficient thermal insulation of new insulation materials. Vehicle insulation and sound insulation noise reduction material selection, has drawn the attention of the relevant state departments. The Ministry of Industry and Information Technology issued on November 11, 2016 "Electric Bus Safety Technical Conditions" clearly states: "4.3.3 Rechargeable energy storage system (or installation of cabin) and the cabin should be used between the flame retardant Insulation material isolation, flame retardant insulation materials should meet the flammability requirements of Class A, the thermal conductivity at 300 ℃ should be less than equal to 0.04 W / (m · K). "Against this background and trends, Joda developed Aluminum Foil Aerogel Blanket becomes the best choice for fire and heat insulation of transportation vehicles.
Second, application examples
Joda aluminum foil aerogel insulation fire-retardant blanket is an excellent fire insulation material to meet the dual characteristics of fire retardant and efficient insulation. In the bottom of the bus fire isolation, body fire insulation and battery box insulation, can be a large number of applications.
Pictured is Joda's electric bus fire insulation solution. Through the battery compartment and the passenger compartment laid aluminum foil aerogel insulation fire retardant blanket to form a fire barrier to prevent the battery in the event of combustion to prevent the spread of fire to fight for the escape time to protect the safety of upper passengers; Organic foam insulation materials to reduce the combustible composition, reducing the spread of fire hazards; through the external battery box with aluminum foil aerogel insulation fire retardant blanket, can effectively reduce the risk of battery accidents, while protecting the battery's low temperature performance.
Foil aerogel insulation flame retardant blanket construction is also simple and quick. The installation of the aerogel insulation blanket is to install the blanket pad at the bottom of the floor, according to customer requirements will be cut into the mat to develop specifications. In this case, the blanket mat is cut to the same size as the floor, and glued to the floor with double-sided tape. Subsequent installation process and the same as the original process, the floor can be installed in the original design site. Slim thickness for easy construction operation, installation of the aluminum foil aerogel insulation flame retardant blanket will not image the original design structure.
Third, experimental verification
After Joda bus production customers on-site fire experiment, foil aerogel insulation fire blanket solution achieved excellent results. The thin aerogel insulation blanket above the brazier, burned at 800 ℃ flames for 20 minutes, the aerogel insulation blanket intact, the back of the temperature is only about 80 ℃. The experiment proved that the aluminum foil aerogel insulation flame retardant blanket can effectively block the spread of fire and ensure the safety of personnel.
After multiple verification, aluminum foil aerogel insulation fire retardant blanket is ideal for fire and heat insulation materials.
