Polyurethane new material is an advanced polymer material with great application value in seven fields of foam plastics, rubber, synthetic leather, fiber, coating, adhesive and functional polymer.At present, polyurethane has developed a large number of special functional materials in automobile, shipbuilding, high-speed railway and intercity track, aerospace, steel, new energy and other industries, meeting the urgent needs of related industries for new materials.
However, the use of polyurethane high-efficiency building energy-saving insulation materials in the real estate industry has been restricted, the main reasons are:
1. Low quality, non-flame retardant polyurethane materials were used by the engineering contractor.
2. From the perspective of market supervision, there are many problems in the building thermal insulation industry, which obviously cannot adapt to the overall goal of building energy conservation.
The main problems include:
(A) the industry is not standardized, and some production enterprises lack of self-discipline;
(B) insufficient market regulation and urgent improvement of regulatory methods.An obvious fact is that one of the common causes of fires related to building insulation is the use of substandard B3 grade insulation.According to the comprehensive analysis of all causes of accidents, it has never been found that the use of qualified grade B2 or above insulation materials caused by fire quality problems;
(C) there is an urgent need for further refinement of the regulatory framework.The lack of operable specific implementation specifications, coupled with the supervision difficulties in the actual operation process, also objectively led to the building external wall insulation material market increasingly chaotic.
Building energy conservation is an important measure to realize low-carbon and green economy in China.At present, more than 95% of new buildings in China are still high-energy buildings, and the energy consumption of buildings has reached 27% of the total energy consumption of the whole society. By 2020, 50% of the national energy consumption will be spent on buildings.Only 10 percent of the newly completed buildings in the city meet the energy conservation standards, and less than 4 percent of the 430 million square meters of existing residential buildings meet the standards.In European and American developed countries, 50% of the building thermal insulation materials are polyurethane thermal insulation materials, but the current utilization rate in China is less than 10%.Pu heat preservation material is one of the world's most recognized can satisfy the environmental protection and energy saving and safety performance of one of the ideal thermal insulation material, with its excellent thermal insulation, waterproof, wind resistance, impact resistance, such as performance, with spray, casting and sheet cover a variety of construction form, is widely used in wall insulation materials, doors and Windows insulation, roof insulation materials, practice proved that the polyurethane thermal insulation materials in addition to make commercial and residential buildings more energy efficient and comfortable outside, also can significantly reduce energy costs.
In order to further standardize the development of building insulation material market, in the spirit of science, from the practical point of view, take into account the two goals of energy conservation and fire prevention, we think from the following three aspects of implementation of supervision.
1. Strictly enforce the law and strengthen the market supervision of building thermal insulation engineering.
Through strict and fair law enforcement, we should increase the cost of breaking the law, establish a compulsory market elimination and withdrawal mechanism for illegal and illegal enterprises, strengthen market supervision in and after the event, and gradually establish a fair and equitable environment for development.
2. A strict market access system should be established to give full play to the auxiliary role of industry associations and carry out training and industry self-discipline.
It is suggested that relevant government departments should establish and improve the market access system to avoid enterprises lacking relevant technical qualifications and management ability from entering this field. Meanwhile, it is also suggested to guide and support the industry associations to carry out training and industry self-discipline work, so as to fundamentally improve the overall level of the building insulation industry.
3. Strengthen the evaluation of building energy saving effect.
It is suggested that the government should organize a third-party organization to establish an evaluation mechanism of building energy saving effect, so as to promote the use of efficient thermal insulation materials and reduce the energy consumption of buildings during use.
We fully believe that as long as the polyurethane production enterprises strictly and conscientiously implement the national and local laws and regulations, then polyurethane efficient building energy conservation insulation materials in the real estate industry will get considerable development.
