Policy support for the development of green buildings is conducive to polyurethane insulation materials

polyurethane rigid foam insulation materials are ideal materials for building energy conservation, low-carbon and environmental protection. In foreign countries, 50% of building insulation materials use polyurethane insulation materials, while only 10% in China. Polyurethane insulation materials have a huge potential market

policies vigorously support green building materials

in January 2013, the general office of the State Council forwarded the green building action plan formulated by the national development and Reform Commission and the Ministry of housing and urban rural development, requiring green building actions to be carried out and mandatory standards for building energy efficiency to be strictly implemented. Content of the standard: "during the 12th Five Year Plan period, China will complete the construction of 1billion square meters of new green buildings; By the end of 2015, 20% of new urban buildings will meet the requirements of green building standards; Complete the heating metering and energy-saving transformation of existing residential buildings in northern heating areas of more than 400million square meters, and the energy-saving transformation of existing residential buildings in hot summer and cold winter areas of 50million square meters; 120million square meters of energy-saving renovation of public buildings and offices of public institutions; 400000 sets of energy-saving demonstrations were implemented for the renovation of dilapidated houses in rural areas

from January 1, 2013, Beijing announced the implementation of 75% building energy efficiency standards

the market share of polyurethane insulation materials is growing rapidly

the initial market share of polyurethane rigid foam insulation materials is only about 1%. In the following years, the consumption of polyurethane rigid foam showed a linear increasing trend. From 2005 to 2010, the average annual growth rate of polyurethane insulation materials in China was 16%. In just one year in 2012, the number of manufacturers of rigid polyurethane composite boards increased explosively to more than 250. In 2012, the third Beijing Automotive Plastics Technology Forum was successfully held a few days ago, and the market share of rigid polyurethane in the major projects of comprehensive transformation of old residential areas in the city reached 65%

however, due to the high price, the comprehensive share of polyurethane insulation materials in China's building energy-saving material market is still not high, less than 10%. It is estimated that by 2015, the market share of polyurethane insulation materials will reach 30% - 40%

the market space is still huge: 100 billion business opportunities need to be leveraged

statistical data show that during the "12th Five Year Plan" period, China's annual average external wall insulation area is 1billion square meters (measured by the proportion of external wall area accounting for 62% of the construction area), which can drive the demand for polyurethane rigid foam from 2013 to 2015, 268600 tons, 314600 tons and 376600 tons. Calculated by 100 yuan/square meter of thermal insulation materials, the external wall thermal insulation Market in China will exceed 100 billion yuan during the "12th Five Year Plan"

the enthusiasm of market procurement needs to be improved. Policy support and standardization of industries

due to the high price, the independent acceptance of the current market is not high. And most of them are substandard and substandard products that are produced irregularly, flooding the market

according to the standard, the combustion performance of polyurethane insulation board is grade B2 and B1, which has flame retardancy, but most of the polyurethane insulation materials in use on the market do not meet this standard. The main reason is cost constraints

at present, compared with flammable and combustible XPS and EP, polyurethane insulation materials are not competitive in price among the external wall insulation materials in the market. The B1 grade polyurethane insulation material per cubic meter is 1800 yuan, while XPS is 650 yuan per cubic meter and EPS is 350 yuan per cubic meter, with a maximum price difference of 1450 yuan. Calculated with a thickness of 5 cm, the maximum price difference per square meter is 73 yuan

for some prescriptive buildings or public buildings, the utilization rate of polyurethane is still very high, but the popularity of polyurethane in residential buildings, especially in medium and low-grade commercial housing, is significantly low. Since 1978, when it was widely produced and put into the market,

little knowledge: polyurethane materials have good thermal insulation, flame retardancy and environmental protection characteristics

common insulation materials include rock wool, polystyrene foam board (EPS), extruded polystyrene foam insulation board (XPS) and polyurethane (PUR). From the three aspects of thermal insulation, flame retardancy and economy, polyurethane rigid foam has outstanding comprehensive performance. It is a standard thermal insulation material and can be widely used in building energy conservation

high environmental protection: using one cubic meter of polyurethane insulation material can reduce carbon dioxide emissions by 270 kg a year. If the consumption of polyurethane insulation materials is 1million tons per year, the carbon dioxide emission can be reduced by 7million tons per year

flame retardant: among thermal insulation materials, only polyurethane materials are flame retardant

thermal insulation: the thermal conductivity of rigid polyurethane thermal insulation materials for buildings is 0 024. Compared with other insulation materials, the heat transfer coefficient is the lowest and the insulation performance is the best
