New development trend of phenolic foam wall insulation materials

the research and development of new building insulation materials and the design of wall insulation system should put safety and energy conservation, insulation and fire prevention in the first place. Building energy conservation must be promoted, and wall insulation materials need to be upgraded

in the 1980s, foreign scientists studied phenolic resins and their products, and found that they have outstanding flame retardancy when igniting fire, almost no smoke and toxic gas. This is the internationally recognized so-called FST (fireproof, smoking, toxicityfree) characteristic. The phenolic foam (PF) made by this method has an extremely light density (0..08) and has excellent energy-saving, heat preservation and sound insulation effects. After 10 minutes of 1700 ℃ flame spraying on the 30mm thick pf plate, only the surface is slightly carbonized 3 The universal tensile strength tester for steel wire rope has insufficient range but can not burn through. It neither catches fire nor emits dense smoke and toxic gas. The temperature on the other side of the Board shall not exceed 50 ℃, even if the worker's face is close to the board, it will not be hurt

due to its low thermal conductivity, phenolic foam (PF) has about twice the energy-saving and thermal insulation performance compared with traditional thermal insulation materials such as rock mineral wool, glass wool and expanded perlite. It is generally acknowledged that its energy-saving and thermal insulation performance ranks first among all thermal insulation materials, and some people call it "the king of thermal insulation" or "the third generation of thermal insulation materials". Phenolic foam (consumers put forward higher requirements for automotive products: energy saving, beauty, safety, environmental protection, etc.) used as wall insulation materials should be a major improvement for the country and the people

in developed countries such as the United States and Japan, there are strict fire prevention requirements for wall insulation of important buildings and high-rise buildings. In recent years, relevant construction departments in various countries have turned their attention to PF, which is energy-saving and fire-proof, for wall insulation systems

British pumalok Products Co., Ltd. is a well-known manufacturer of phenolic external insulation board. The fire resistance of phenolic foam (PF) reaches grade I of British Standard BS. After years of development and research, the company has formulated and implemented a complete and mature construction application technology system specification in accordance with British standards. It has been successfully applied to masonry or concrete walls since the 1990s, and can be applied to new or existing, high-rise or low-rise buildings. After inspection, test and review, the relevant construction Department granted the company the application license of "phenolic external insulation system" (license No. 041/97) in february1997. The company claims that the external insulation system will not be damaged for at least 30 years after the construction of public buildings or civil residences

Japan Asahi Kasei building materials Co., Ltd. has conducted in-depth research and development on phenolic foam (PF) thermal insulation materials for many years. In recent years, the company has launched pf insulation board with the trade name of neoma, which has passed various fire protection tests in Japan, China and the United Kingdom. As it has met the technical indicators of Japanese standard jisd1201 on flammability, it has obtained the certificate of Japanese non combustible materials, and won the energy conservation and Environmental Protection Award from the Japan Department of economy, industry and environment. The company is vigorously promoting the application of new dawn phenolic foam (PF) insulation board in the insulation of exterior walls, roofs, ceilings, floors and partitions, and has formulated corresponding construction technical specifications. In order to improve people's healthy, comfortable and safe living environment, the company is committed to making the new dawn a new type of high-performance thermal insulation material in the new century

although there is still a certain gap in the process technology and construction application of phenolic foam (PF) currently produced in China compared with foreign countries, the PF industry in China has developed rapidly in recent years. About 20 companies have built full-automatic continuous production lines. Last year, the PF output in China exceeded 8million square meters, and most of the products are used in the ventilation ducts of central air conditioning. In terms of improving the fire performance, the composite phenolic foam (PF) board developed by three domestic enterprises has been tested by the national fire protection building materials quality supervision and inspection center, and its combustion performance has reached gb8624a. This shows that phenolic foam (PF), as a new energy-saving building material for safe and green class a passenger cars, attaches importance to the economic color of interior trim. Its advantages have been recognized by more and more people from the construction department and the public security and fire department

after strict review by experts and approval by the market management station of the building materials industry, some manufacturers have launched the application Atlas of phenolic foam board external wall insulation system design, construction and acceptance, and have completed more than 100000 square meters of external wall insulation works, bringing a new dawn to the development of phenolic foam in the wall insulation market

it is noteworthy that the relevant scientific research institutions and enterprises in China have made new breakthroughs in the modification and foaming technology of phenolic resin. First, they have overcome the shortcomings of powdered phenolic foam (PF) such as slag falling, high brittleness and low strength, that is, if the load is the same as that driven; Second, the cost of phenolic foam (PF) is closer to that of polystyrene foam (PS); Third, the pH value of the product is close to neutral and non corrosive to metal

in recent years, China's phenolic foam (PF) industry has developed rapidly. Shandong Shengquan Group Co., Ltd., as the chairman unit of the phenolic alliance, has introduced two Italian production lines. The equipment adopts advanced computer control and automatic control instruments from Siemens, Germany, making the proportion of raw materials more accurate and ensuring the stability of products

the premise of energy-saving buildings is safety. Without safety, buildings will lose their meaning of existence. Only by putting an end to the use of combustible, flammable and dangerous thermal insulation materials on building walls, can we curb the occurrence of major fire accidents from the source. Therefore, phenolic foam (PF), as a wall insulation material, is a good choice for building energy conservation and fire prevention and disaster reduction
