Abstract

The present invention provides an aerosol fire suppression apparatus with a high temperature ablation resistant thermal insulating layer and preparation method thereof, wherein the aerosol fire suppression apparatus comprises enclosure, thermal insulating layer, aerosol generating chemical agent, cooling material, and initiator. The thermal insulating layer is made of silicone rubber material, comprising silicone rubber substrate, cross-linking agent, fire retarding agent, high temperature resistant material, coupling agent and catalyst. The preparation method of the aerosol fire suppression apparatus comprises: casting aerosol generating chemical agent and silicone rubber into an integral piece in a mold, and cross-linking and solidifying at room temperature, to form a thermal insulating layer; loading the initiator in the chemical agent, filling a cooling material over the initiator, and covering the cooling material with a screen; loading the thermal insulating layer that contains the aerosol generating chemical agent, initiator, and cooling material into the enclosure of the apparatus, and sealing the thermal insulating layer with a cover. Compared to existing apparatuses in the prior art, the apparatus in the present invention has the following advantages: the silicone rubber casting process is simple and suitable for mass production; the silicone rubber thermal insulating layer delivers good heat insulation effect; the packed aerosol generating agent can burn stably without flying flame or explosive burning phenomenon.
