Energy saving and fire prevention of organic thermal insulation materials must take into account

according to the comprehensive work plan for energy conservation and emission reduction in the 12th Five Year Plan, building energy conservation has undertaken about 17% of the total energy conservation target of the whole society in the 12th Five Year Plan. To achieve the goal of building energy conservation, we cannot do without the wide application of polystyrene (PS), polyurethane (PU), phenolic and other organic exterior wall insulation materials. It is necessary to solve the problem of fire safety through the technical integration of materials and building structural systems such as fire separation belts, so that organic thermal insulation materials can really shoulder the responsibility

from the current situation, in order to play a greater role in building external insulation, organic thermal insulation materials need to overcome the barrier of fire safety. That is, in addition to ensuring that the flame retardant performance of the material itself meets the standard, we should also strengthen the integration of various technologies and the development and research of the external wall insulation system, so as to make the organic insulation materials develop their strengths and circumvent their weaknesses, and truly achieve both energy conservation and fire prevention. This is the common aspiration expressed by experts and enterprise representatives at the national external wall insulation and energy-saving structure technology exchange and promotion meeting held in Nanjing from July 21 to 22

with the deepening and promotion of China's energy conservation and emission reduction tasks, building energy efficiency standards are also constantly improving. According to quhongle, director of the office of new wall materials and structures technology of the science and technology development center of the Ministry of housing and urban rural development, according to the "12th Five Year Plan" for building energy conservation, by the end of the "12th Five Year Plan", China's building energy conservation should strive to achieve the goal of 116 million tons of standard coal, of which 45 million tons of standard coal can be saved by developing green buildings and strengthening new buildings. The realization of this goal is inseparable from the contribution of building envelope to building energy conservation. In the current situation, the energy-saving level and fire safety of building envelope are more important than ever

it is understood that at present, the thermal insulation materials commonly used in building envelope in China are diversified, mainly divided into organic materials and inorganic materials. Pu, expanded polystyrene (EPS), extruded polystyrene (XPS) and other organic materials are characterized by excellent thermal insulation performance, but poor fire resistance; Inorganic materials have excellent fire resistance, but inferior thermal insulation performance. Therefore, for buildings with high energy-saving requirements, organic thermal insulation materials bear the heavy responsibility, and solving the problem of fire safety has become the primary technical topic. At present, many domestic enterprises have explored and gained in this regard

linyongfei, chairman of Jiangsu Lvyuan new materials Co., Ltd., said that as a material supplier, Jiangsu Lvyuan has been committed to developing Pu exterior wall insulation materials with higher fire rating. Through the application of structural flame-retardant polyether in Pu, the high-performance and thermosetting Pu developed by the company has reached B1 (flame-retardant) level with the depletion of oil resources, and the technology has become increasingly mature. The industrialization of this structural flame-retardant PU material will effectively improve the long-term flame-retardant performance of PU. At the same time, the company developed high-performance organic materials and inorganic composite insulation materials to complement each other. Nanjing faningge Energy Saving Technology Co., Ltd. improved the transformation and upgrading of EPS materials in China by adjusting the formula, and PS was applied to the production of XPS, which improved the flame retardant performance of XPS and reduced molten dripping at the same time

experts such as huangmaosong, a distinguished professor at the school of materials science and engineering of Shanghai Institute of applied technology, and Ji Guangqi, a researcher at the Institute of building fire protection of the Chinese Academy of Building Sciences, emphasized that external wall insulation is a systematic project, and it is biased to rely solely on a certain material or overemphasize the performance of a certain aspect. Only the performance of thermal insulation materials and external wall structures are set, but at present, a considerable part of ophthalmic materials have not yet reached idealization, Therefore, seeking new technologies and methods, constantly improving existing ophthalmic materials or preparing new functional ophthalmic materials is a hot plan in the field of biomaterials research. Organic combination and mutual matching, strengthening materials and fire barrier, etc. 6 Only by pressing the "start" key to build the technical integration of structural system, can we fundamentally achieve both building energy conservation and fire safety
