At present, with the occurrence of many building thermal insulation fire incidents, the new environmental protection and green building industry is being paid more and more attention by the public, which has aroused the thinking of thermal insulation and fire protection from all walks of life, and the fire performance of thermal insulation materials has attracted great attention in the industry. Experts believe that the increasingly popular "passive" energy-saving buildings in European countries are developed on the basis of low-energy-consumption buildings. By optimizing the building design, the building shape coefficient can be controlled; composite thermal insulation materials can be used to meet energy-saving standards. At present, many polyurethane thermal insulation material manufacturers have been actively improving their production processes, and mass-produced composite A-level rigid foam polyurethane composite panels with B1-level core materials and flame-retardant inorganic materials coated on both sides. Experts said that the composite material itself not only maintains the thermal insulation performance of polyurethane materials, but also improves the high fire performance, and can also reduce the probability of fire during construction, which is a trend in the development of the polyurethane thermal insulation material industry.

In the 2013 China International New Materials Exhibition, polyurethane thermal insulation material enterprises accounted for half of the country. According to the person in charge of the company in the industry: "In recent years, the consumption of polyurethane thermal insulation materials has increased significantly. Under the background of the country's vigorous promotion of green and energy-saving building construction, the development prospects of polyurethane thermal insulation materials are very broad.

There are many types of building exterior wall insulation materials in my country, including rock wool, glass wool, foam ceramics, foam glass, etc. Polyurethane insulation materials are new materials emerging in recent years. China has become the fastest growing region in the world's polyurethane industry. China's urbanization is developing rapidly. Under the background of the country's vigorous promotion of green and energy-saving building construction, the development prospects of polyurethane thermal insulation materials are very broad.

To sum up, the polyurethane industry has a good market prospect. Throughout the world, the polyurethane composite panels of western developed countries have already entered a mature development period and entered the stage of innovative research and development. Industry insiders said that the country's call for building energy conservation has brought opportunities to the polyurethane insulation industry. Grasping market trends and improving production efficiency and production processes are the top priorities of many polyurethane companies. The Asian market is growing rapidly, and many multinational chemical companies have focused their business. and R&D centers have been transferred to the Asian and even Chinese markets, bringing new business opportunities to the domestic polyurethane composite industry.

The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeating urethane groups on the main chain. Its raw materials can be divided into isocyanates such as MDI and TDI, polyols such as PO and PTMEG and additives such as DMF. At present, the production capacity and production supply of MDI diphenylmethane diisocyanate and TDI toluene diisocyanate, the key raw materials of domestic polyurethane, are sufficient; the downstream products of polyurethane will benefit from the domestic demand market and form a number of new economic growth points.

The downstream products of polyurethane mainly include two systems, case system and foam system. CSAE system is mainly used to produce coatings, adhesives, sealants and elastomers. The foam system mainly includes polyurethane soft foam and rigid foam. The soft foam mainly includes various cushion materials for furniture and vehicles. The rigid foam includes the thermal insulation and waterproof spray foam of the house wall and the pipeline insulation material, etc. It can be seen that the application field of polyurethane is broad. It is a field with good prospects and an important new chemical material industry advocated by the state.

Polyurethane composite panels for construction conform to the national standard GB/T 23932-2009. This product is a bimetallic, single-metallic and non-metallic composite panel with polyurethane rigid foam as the thermal insulation layer. It is usually used in industrial plants, logistics storage, Integrate the wall and roof envelope system of the house. Generally speaking, polyurethane composite panels can be used in almost all kinds of construction needs, including industrial plants, public buildings, modular houses, purification projects and other construction fields.

It is estimated that the thermal insulation effect of 4 cm thick polyurethane insulation material is equivalent to that of 1.7 m thick ordinary red brick, and the thermal insulation effect is 2 to 3 times that of traditional rock wool, and 2 times that of polystyrene board. The use of polyurethane material can reduce the volume of the thermal insulation material while ensuring the thermal insulation effect. In the era of increasingly high housing prices, increasing the usable area will naturally bring considerable economic value. Polyurethane exterior wall insulation material has the advantages of low thermal conductivity and high efficiency and energy saving. It is estimated that every cubic meter of polyurethane can reduce heating fuel consumption by 200 liters and reduce carbon dioxide emissions by 570 kilograms per year.

With the improvement of building energy-saving standards and fire protection requirements in my country and the completion of the preparation of polyurethane building insulation standards, polyurethane rigid foam will become an important part of building insulation materials. In the case of many high-rise buildings and high density in my country, the challenge of building thermal insulation and fire prevention is greater than that of foreign countries. Industry insiders predict that thermosetting thermal insulation materials such as polyurethane rigid foam are superior to thermoplastic thermal insulation materials in terms of combustion performance, and will usher in good development opportunities. As the country increases the promotion of new thermal insulation materials, the utilization rate of polyurethane in the region is increasing year by year, and polyurethane wall thermal insulation materials have great market potential in my country and even the world.

Due to the particularity of its material, in addition to being widely used in the above-mentioned construction fields, people also give full play to its characteristics and apply it to a wider field, such as the inner partition wall of ships, cold storage, highway soundproof walls, etc. , and with the continuous progress of science and technology and the upgrading of people's work and life needs, so as to better meet people's needs and create a broader space in the building materials industry where new products are emerging one after another. At present, there are only a handful of enterprises with the most advanced polyurethane composite panel production lines in China. Changzhou Yanghu Refrigeration Equipment Co., Ltd. has launched a polyurethane composite panel production line with the latest information at home and abroad, hoping to better serve our customers.

Polyurethane is not widely used in the construction industry as an external wall insulation application, but the government attaches great importance to the promotion of building energy-saving materials. In addition, our company has domestic first-class chemical research institutions and the most advanced equipment in the world. Changzhou Yanghu Refrigeration Equipment Co., Ltd. The company has unique advantages in the development of polyurethane thermal insulation industry. In this way, a complete industrial chain will be gradually formed, which will stimulate the product demand of upstream enterprises and promote the transformation and upgrading of the construction industry.
