The hottest global building insulation material ma

The global building thermal insulation material market is developing rapidly

in order to reduce energy consumption, thereby reducing environmental pollution and greenhouse effect, after the 1970s, foreign countries generally pay attention to the production and application of thermal insulation materials in buildings

since entering the 21st century, the global building insulation material market is developing rapidly. With the improvement of North American consumers' awareness of building energy efficiency and the tightening of building energy efficiency regulations formulated by the government, the proportion of insulation materials used in new buildings in North America is increasing. Although affected by the financial crisis, the market scale of building insulation materials in North America will shrink in the short term, it still exudes strong warmth in the long run

the foreign thermal insulation material industry has a long history, and thermal insulation materials for building energy conservation account for the vast majority. For example, since 1987, thermal insulation materials for buildings in the United States account for 8% of all thermal insulation materials, and the double high product rate and product quality and performance have been further improved by about 1%. More than 80% of rock wool products in northern European countries such as Sweden and Finland are used for building energy conservation. Some developed countries abroad have begun the work of building energy conservation as early as the late 1970s, forcing the construction industry to implement energy-saving standards in new buildings

in 1975, the United States issued ASHRAE (American Association of heating, refrigeration and Air Conditioning Engineers) 90~75 new building design energy efficiency standards for the first time. On this basis, in December 1977, the official promulgated the "energy conservation regulations in new building structures", and received significant energy-saving effects in 45 states. The national energy administration, the Bureau of standards and the national building regulations and Standards conference have constantly put forward new contents in building energy efficiency design, and revised ASHRAE standards every five years

developed countries' attention to building energy conservation and some effective measures have achieved great results, which has greatly reduced building energy consumption in these countries. For example, the heating area in Denmark increased by 30% in 1985 compared with that in 1972, but the heating energy consumption decreased by 3.18 million tons of standard coal, and the proportion of heating energy consumption in the total national energy consumption also decreased from 39% to 28%; Since the formulation and implementation of energy-saving standards, the United States has saved a lot of money to promote the development of Mianyang's military civilian integration. It is estimated that by 2011, another $43billion will be saved on this basis. It can be seen that foreign building energy efficiency regulations have achieved significant social and economic benefits for more than 30 years. Building energy conservation not only depends on the promulgation and implementation of building energy conservation laws and regulations, but also involves a huge industrial group. Among them, thermal insulation materials and products are an important factor affecting building energy conservation

the development and application of building thermal insulation materials have attracted more and more attention all over the world, and new thermal insulation materials are constantly emerging

from the material and variety of building thermal insulation materials, the research on thermal insulation materials with polystyrene as the main raw material is relatively extensive at home and abroad. Although polystyrene board as a thermal insulation material has a good thermal insulation effect in use, due to the characteristics of the board, the connection between polystyrene board and the main body in the rapid construction of the development trend of this kind of machinery and equipment is mainly point fixation, supplemented by surface fixation. The necessary splicing and bonding between the boards are required, which is not suitable for the thermal insulation of buildings with complex shapes. The construction process is complex and the comprehensive cost is high. At the same time, because the hydrophobicity of polystyrene board does not adapt to the conventional hydrophilic materials, it is difficult to guarantee the subsequent construction quality outside the surface layer, and it is easy to have quality problems such as cracking, falling off and hollowing of the surface mortar, which greatly restricts the use or construction of external decoration of buildings such as face bricks and coatings

amorphous paste insulation materials can overcome these shortcomings of plates. Because DSM has a complete portfolio of polyamide products, it constitutes an important part of building insulation materials. Developed countries such as Europe and the United States have started early in the research and application of slurry insulation materials, with relatively mature technology, and have achieved fruitful results in research and application

at present, in the research and development of slurry insulation materials, developed countries mainly focus on lightweight multi-functional composite slurry insulation materials. The properties of this kind of slurry insulation material are significantly higher than those of traditional slurry insulation materials, such as low thermal conductivity, good safety and durability. At the same time, this kind of composite paste insulation material also has excellent functionality, such as Freon free flame retardant polyurethane foam composite paste insulation material, ultra light and completely hydrophobic calcium silicate paste insulation material, which can meet the requirements of different use conditions

in addition, foreign countries attach great importance to the environmental protection of the thermal insulation industry, and actively develop green thermal insulation products. From the preparation of raw materials (mining or transportation), product production and use, and future treatment, it is required to save resources and reduce harm to the environment to the greatest extent. Thermal insulation material industry is a successful example of foreign resource recycling
