The fireproof silicone rubber composite material is characterized in that: the fireproof silicone rubber composite material is obtained by the hot-pressing and composition of a silicone rubber fireproof isolation layer (1), a silicone rubber flame-retardant cooling layer (2), a silicone rubber ablation-resistant layer (3) and a silicone rubber substance layer (4); and the silicone rubber fireproof isolation layer, the silicone rubber flame-retardant cooling layer, the silicone rubber ablation-resistant layer and the silicone rubber substance layer are arranged from outside to inside in sequence. The fireproof silicone rubber composite material has the advantages of good fireproof effect and good heat insulation effect.

Description

technical field

[0001] The invention relates to a fire-resistant silicone rubber composite material and a preparation method, which are suitable for aircraft firewalls, internal fire-proof equipment of other high-speed transportation vehicles, and military-related equipment. Background technique

[0002] Due to the requirements of the special environment of the aircraft, it is necessary to build a firewall, which is a metal plate structure that isolates the potential fire area of ​​​​the aircraft from the adjacent cabin. Fire-resistant silicone rubber is an important part of it. In addition to the flame-retardant properties of silicone rubber, higher flame impact resistance requirements are also required for materials. The material is required to form a ceramic barrier layer under extremely high temperature flames to protect the backside components from being damaged by strong heat. There are many foreign research reports on fire-resistant silicone rubber. For example, US ...
