Study on Fire Prevention of Wall Insulation Organic Materials Wang Pengxiang1, Zhang Cunwei2, Li Xiangmei3, Yang Rongjie3 School of Materials Science &Engineering, Beijing Institute of Technology National Engineering Research Center of Flame Retardant Materials,100081,Beijing Keywords: Organic, Wall Insulation Materials, Fire Prevention, Development Abstract: This article described the technical progress of the wall insulation organic materials and analyzed other relevant factors in recent years about the insulation materials policies changes and market changes.
The second type of wall insulation materials are composite materials, such as phenolic foam insulation materials, reaching flame retardant materials B1 level (fire).
They belong to the combustible materials (B2 fire).
A: incombustible materials.
B2: combustible construction materials.

Influence barrier property of thin film packaging materials are the main factors.

In this paper, we focus on the need for the study of interface characteristics between different reinforced materials and clay, by making indoor drawing test with two kinds of reinforced materials commonly used in engineering and the same clay.
With the rapid development of Reinforced earth technology, different reinforced materials are also gradually applied to reinforced earth, In this paper, we focus on the need for the study of interface characteristics between different reinforced materials and clay, by making a indoor drawing test with two kinds of reinforced materials commonly used in engineering and the same clay.
The two kinds of reinforced materials drawing test results is shown in table 3.
