Building materials release various toxic gases, and the closed indoor environment has high humidity, which will provide a suitable living environment for mold and bacteria. Therefore, people’s demand for green building materials is becoming more and more urgent and widespread, and the demand for green building materials is becoming more and more urgent.

Research on building materials also came into being.

Come and find out more about it with me below.

A brief analysis of the characteristics of green building materials and their development status in my country 2. Characteristics of green building materials Green building materials are also called "ecological building materials", "healthy building materials" or "environmental protection building materials". It is not a simple type of building materials, but a " A comprehensive evaluation of the qualities of "energy saving, environmental protection, health and safety" requires a comprehensive evaluation of its entire life cycle including raw material collection, production process, construction process, use process and waste disposal, and must fully meet the green building materials evaluation standards.

1. Basic characteristics of green building materials 1. Low consumption: From the perspective of raw material selection, the raw materials used in the production of green building materials use as few natural resources as possible, and use a large amount of tailings, waste residue, garbage, waste liquid and other wastes; 2. Low energy consumption: from

From the perspective of production technology, green building materials adopt low-energy-consuming manufacturing processes and production technologies that are non-polluting to the environment; 3. Light pollution: From the perspective of production process, green building materials must not use formaldehyde, halide solvents or aromatic solvents during product preparation or production.

Group hydrocarbons, products must not contain mercury and its compounds, pigments and additives of lead, cadmium, chromium and other metals and their compounds must not be used, and other pollutants harmful to the human body and the environment must not be used; 4. Multi-function:

From the point of view of the use process, the design of green building materials products is to improve the production environment and improve the quality of life. That is, the products not only do not harm human health, but also are beneficial to human health. The products have multiple functions, such as antibacterial, sterilization,

Anti-mildew, deodorization, heat insulation, flame retardant, fire prevention, temperature regulation, humidity regulation, degaussing, anti-ray, anti-static, etc.; 5. Recycling: From the perspective of the waste process, green building materials products can be recycled or recycled.

Waste that does not pollute the environment.

2. The meaning of green building materials 1. It is a high-performance traditional building material produced at the expense of relatively minimal resource and energy consumption and environmental pollution; 2. It can significantly reduce building energy consumption (including energy consumption during production and use).

energy consumption); 3. It has higher usage efficiency and excellent material properties, thereby reducing material consumption; 4. It has building materials that improve the ecological environment and health care functions of the living room; 5. It can be used in large quantities

Building materials from industrial waste.

A brief analysis of the characteristics of green building materials and their development status in my country 3. The development status of green building materials in my country Since the reform and opening up, with the rapid development of my country's economy and society and the increasing living standards, people have increasingly higher requirements for the quality and environmental protection of housing. The higher the number, the more intensive and extensive the research, development and use of green building materials will be.

The "greening" of construction and decoration materials is mankind's new requirement for this ancient field of building materials, and it is also the only way for the sustainable development of building materials.

my country's environmental labeling was announced in October 1993. On May 17, 1994, the China Environmental Labeling Product Certification Committee was announced in Beijing. In 1994, environmental labeling was first implemented in 18 products in 6 categories. Water-based coatings were the first building materials A batch of products subject to environmental labeling.

In May 1998, the Ministry of Science and Technology, the National Natural Science Foundation of China and the 863 Program New Materials Expert Group jointly held an "Ecological and Environmental Materials Seminar" and determined that "Ecological and Environmental Materials" should have both satisfactory performance and excellent environmental coordination.

, and materials that can improve the environment.

Although the development of "green building materials" in our country has achieved some results, it is still in its infancy. In the future, we must continue to develop in the direction of saving resources, energy, health, safety, and environmental protection, and develop more and more high-quality and low-cost products.

Green building materials products improve the quality of human living environment and ensure the sustainable development of our society.

With the rapid growth of the world's population, it has become a very important and arduous task to solve the housing problem of the large population and to achieve safety, comfort and health. The basis for completing this task is to vigorously develop green building materials.

According to incomplete statistics from the China Building Decoration Association, decoration projects across the country have been on a straight-line rise in recent years, reaching 60 billion yuan in 1994, 85 billion yuan in 1995, and exceeding 100 billion yuan in 1996. It is expected to reach 100 billion yuan in 2000.

200 billion yuan, it can be seen that interior decoration has become a hot spot for investment in homes and public places, and the decoration boom will become a potentially huge market for a considerable period of time. This undoubtedly provides a golden opportunity for the development of green building materials.
