Characteristics of Green Building Materials and Their Development Status in China
2. The characteristics of green building materials
Green building materials, also known as "ecological building materials", "healthy building materials" or "environment-friendly building materials", are not simple building materials, but a comprehensive evaluation of the energy saving, environmental protection, health and safety of building materials. It requires a comprehensive evaluation of its whole life cycle, including the adoption of raw materials, production process, construction process, use process and waste disposal, in order to fully meet the evaluation standards of green building materials.
First, the basic characteristics of green building materials
1, low consumption: from the perspective of raw material selection, raw materials used in the production of green building materials use as little natural resources as possible, and use a lot of wastes such as tailings, waste residue, garbage and waste liquid;
2. Low energy consumption: in terms of production technology, green building materials adopt low energy consumption manufacturing technology and production technology that does not pollute the environment;
3. Light pollution: From the production process, formaldehyde, halide solvents or aromatic hydrocarbons shall not be used in the preparation or production of green building materials, and the products shall not contain mercury and its compounds, and pigments and additives of various metals and their compounds such as lead, cadmium and chromium shall not be used, and other pollutants harmful to human body and environment shall not be used;
4. Multifunctional: From the use process, the design of green building materials products is aimed at improving the production environment and improving the quality of life, that is, the products are not only harmful to human health, but also beneficial to human health. Products have antibacterial, bactericidal, mildew-proof, deodorizing, heat insulation, flame retardant, fire prevention, temperature regulation, humidity control, degaussing, radiation protection, antistatic and other functions;
5. Recycling: From the perspective of waste treatment process, green building materials products can be recycled or reused, and there is no environmental waste.
Second, the meaning of green building materials
1 is a high-performance traditional building material produced at the cost of relatively low resource and energy consumption and environmental pollution;
2. Building materials products that can greatly reduce building energy consumption (including energy consumption during production and use);
3, it has high use efficiency and excellent material properties, thus reducing material consumption;
4. It is a building material with the functions of improving living environment and health care;
5. It can make great use of industrial waste building materials.
Characteristics of Green Building Materials and Their Development Status in China
Third, the development status of green building materials in China
Since the reform and opening up, with the rapid development of China's economy and society and the increasing improvement of living standards, people have higher and higher requirements for the quality and environmental protection of housing, which makes the research, development and use of green building materials more and more in-depth and extensive. The greening of building decoration materials is a new requirement for the ancient building materials field and the only way for the sustainable development of building materials.
China Environmental Label was released on June 1993, and China Environmental Label Product Certification Committee was established in Beijing on May 17, 1994. 1June, 1994, environmental labeling was first implemented in six categories of 18 products. Waterborne coatings are the first products to implement environmental labeling.
1In May, 1998, the Ministry of Science and Technology, the National Natural Science Foundation of China and the Expert Group on New Materials of the 863 Program jointly held the "Seminar on Eco-environmental Materials", and determined that "Eco-environmental Materials" should be materials with satisfactory performance, excellent environmental coordination and environmental improvement.
Although some achievements have been made in the development of "green building materials" in China, it is still in the primary stage. In the future, we will continue to develop in the direction of resource saving, energy saving, health, safety and environmental protection, and develop more and more inexpensive green building materials products to improve the quality of human living environment and ensure the sustainable development of our society.
With the rapid growth of the world population, it has become a very important and arduous task to solve the housing problem of a large number of people and realize safety, comfort and health, and the basis for completing this task is to vigorously develop green building materials.
According to the incomplete statistics of China Building Decoration Association, in recent years, China's decoration projects have been in a straight upward trend,160 billion yuan in 994,185 billion yuan in 995, 1996 1000 billion yuan, and it is estimated that it will reach 200 billion yuan in 1000. It can be seen that interior decoration has become a concern of families and the public.
