Description

A kind of silicon rubber composite material
Technical field
The present invention relates to a kind of silicon rubber composite material, especially a kind of silicon rubber composite material for having fire-proof function, The material is suitable for aircraft fire protection wall, the interior fire protection equipment of other high speed means of transport and military relevant device etc..
Background technique
Because the requirement of aircraft particular surroundings needs to establish firewall, this is a kind of aircraft is potentially played flame range and closed on The metal plate structure of cabin isolation.Fireproof silicone rubber is its important component, in addition to the flame-retardant nature for requiring silicon rubber, is also mentioned to material The requirement of higher fire-resistance flame impact is gone out.It is required that material can form the barrier layer of ceramic under the flame of very high temperature, with Back part is protected not damaged by heat-flash amount.
The research foreign countries correlative study report of fireproof silicone rubber is more.It mentions with silicon rubber such as U.S. Patent No. 5047449 Composite material composed by glue, metal oxide borax and mica or frog stone.U.S. Patent No. No. 5508321 and No. 4694030 The middle fire prevention dilatant being formed by combining using silicon rubber combination expanded graphite silicate.The RTV2757 that GE company of the U.S. develops Thixotropic silicon rubber foam layer has good heat-resisting and heat-proof quality.After applying a thin layer on cardboard, it is placed in 2780 DEG C of flames Lower 60s, back temperature are only raised to 29 DEG C by 22 DEG C, and protected fresh flower is not withered.
A kind of patented technology of Dow Corning Corporation's development & production, is added to the wollastonite of 7%-20% in liquid silastic With the reinforced filling of 10%-60% etc., the test piece of thick 0.635cm calcination 15min, back under 1093 DEG C of Bunsen burner of flame is made It does not burn or burns in face.
One kind of John Meaney design is used for aircraft engine light fire-proof layer.First layer is applied in metal part surface Organic silicon sealant spreads ceramic fiber fabric when unvulcanized above it, then applies second layer organic silicon sealant again. Organic silicon sealant has used the space sealing agent that the trade mark of Dow Corning Corporation is 902006, and ceramic fiber cloth uses 3M company The product of 312 series of Nextel.This thermal protection shield is not burnt for 15 minutes under 1093 DEG C of flame, and has lightweight, resistance to molten Agent, oil resistant and water resistant wash away and the advantages of anti-vibrations.But there are its products thicker, shorter than great and fire resistance period etc. to ask Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of fire prevention, the fireproof silicone rubber composite material of good heat-insulation effect.
To achieve the goals above, the technical solution adopted by the present invention is that：A kind of fireproof silicone rubber composite material, it is by silicon Rubber fire-resistant separation layer 1, silicon rubber flame-retardant cooling layer 2, silicon rubber anti-ablation layer 3,4 hot pressing of ontology silastic-layer are combined, Silicone rubber fireproof separation layer, silicon rubber flame-retardant cooling layer, silicon rubber anti-ablation layer, ontology silastic-layer successively cloth from outside to inside It sets.
The beneficial effects of the invention are as follows：
1) silicone rubber fireproof separation layer 1 can generate oxygen in diluent air while heat absorption and polymer is decomposed and generated Combustible gaseous object, and protective gas blocking oxygen can be released, flame retardant effect is played, which also has suppression cigarette characteristic.The material When meeting open fire, the phenolic resin on surface, which is carbonized rapidly, forms multi-layer fireproofing carbon-coating with expanded graphite and montmorillonite, then relies on glass After fiber or carbon fiber network form strict thermal insulation layer, can completely cut off or weaken hot transmitting, and hydrotalcite is heated, release water and Carbon dioxide makes material not burn, not smoke, does not generate toxic gas, in addition the specific gravity of the material is lighter.Cutting silicon rubber, The burn cycle that heat and oxygen three elements are constituted, the present invention have good fire retardant effect.
2) when meeting with flame, silicon rubber flame-retardant cooling layer 2 can generate the oxygen in diluent air and be gathered while heat absorption It closes object and decomposes the combustible gaseous object generated, and protective gas blocking oxygen can be released, play fire-retardant cooling effect.
3) silicon rubber anti-ablation layer 3 can resist the ablation of flame, protect ontology silicon rubber.
4) when meeting fire, silicone rubber fireproof separation layer, silicon rubber flame-retardant cooling layer, silicon rubber anti-ablation layer can form more Layer fire prevention isolation film, hot transmitting can be completely cut off and weaken by having, and prevent flame from burning away.Ontology silastic-layer energy and metal base plate It combines, does not generate or seldom generate the dense smoke or toxic gas released when burning.It is special to be applicable in production aircraft The firewall of the requirement of environment fireproof silicone rubber material.It can also make rapid (aircraft, steamer cabin, train vehicle Compartment, subway carriage, cage etc.), interior of building fire proofing material, military equipment, fire-fighting tool etc..
