Abstract

The invention relates to a silicone rubber composite material. The silicone rubber composite material is prepared from a silicone rubber fireproofing and isolation layer (1), a silicone rubber flame-retardant and cooling layer (2), a silicone rubber anti-ablation layer (3) and a body silicone rubber layer (4) through hot-pressing compositing, wherein the silicone rubber fireproofing and isolationlayer (1), the silicone rubber flame-retardant and cooling layer (2), the silicone rubber anti-ablation layer (3) and the body silicone rubber layer are sequentially distributed from outside to inside. The silicone rubber composite material has good flame-retardant and fireproof effects and is suitable for preparing fireproof silicone rubber materials for firewalls for airplane special environments.

Description

technical field

[0001] The invention relates to a silicone rubber composite material, in particular to a silicone rubber composite material with a fireproof function. The material is suitable for aircraft firewalls, internal fireproof 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.

[0003] There are many foreign research repor...

Embodiment 1

[0016] A fire-resistant silicone rubber composite material, which is composed of a silicone rubber fire-proof isolation layer 1, a silicone rubber flame-retardant cooling layer 2, a silicone rubber ablation-resistant layer 3, and a body silicone rubber layer 4. The silicone rubber fire-proof isolation layer, The silicone rubber flame-retardant and cooling layer, the silicone rubber anti-ablation layer, and the body silicone rubber layer are arranged in sequence from outside to inside.

[0017] The above-mentioned fireproof silicone rubber composite material is prepared according to the following steps:

[0018] 1. Preparation of semi-finished silicone rubber fireproof isolation layer: the material of silicone rubber fireproof isolation layer is prepared from matrix, fireproof filler, reinforcing material, crosslinking agent, catalyst and adhesive raw materials. The parts by weight of each raw material are: 100 parts of matrix, 100 parts of fireproof filler, 1 part of reinforci...
