Description
Technical field
The present invention relates to silicone rubber art more particularly to a kind of silicon rubber with compared with strong interface adhesive property.
Background technique
Silicon rubber is widely used as coating, adhesive and sealing material because of its electrical insulating property, weatherability, corrosion resistance etc.
Material.Especially in solid propellant rocket field, the heat insulation layer of silicon rubber matrix is expected to become novel solid propellant rocket
Heat insulation layer.Silicon rubber heat insulation layer temperature use scope is wide, glass transition temperature be lower than -50 DEG C, have excellent ablation resistance,
It is splendid without smoke performance, extraordinary storge quality, good solvent resistant transfer ability, combine weather-proof, hydrophobic, insulation
Property.But silicon rubber also limits its development because of the Some features of itself simultaneously and uses, such as high density, low-intensity, poor
Interfacial adhesion etc..Maximum restraining factors are poor interfacial adhesions.Silastic surface activity is poor, while not having again
There is the group that can be connected chemically, therefore the research of silicon rubber interfacial adhesion enhancing is extremely must for the application of silicon rubber
It wants.
Summary of the invention

Preferably, this has the silicon rubber compared with strong interface adhesive property, in parts by weight, mainly prepared by following material and
At: 100 parts of raw-silastic continuously material；7 parts of curing agent；10 parts of tackifier；1 part of crosslinking agent；0.3 part of catalyst.
Preferably, the curing agent is Methyl Hydrogen Polysiloxane Fluid.
Preferably, the tackifier are silane coupling agent.Further, the tackifier be bisamide silane coupling agent or
Vinyl-based silane coupling agent.
Preferably, the crosslinking agent is trimethylol-propane trimethacrylate.
Preferably, the catalyst is chloroplatinic acid, palladium catalyst.
Compared with prior art, the invention has the benefit that by the way that suitable three hydroxyl of crosslinking agent containing polyhydroxy is added
Trimethacrylate improves the craftsmanship of silicon rubber, and it is bonding with metal strong to effectively increase silicon rubber
Degree；The adhesive property of silicon rubber is also effectively increased by the way that suitable tackifier silane coupling agent is added.The present invention passes through selection
Suitable auxiliary agent effectively increases the interfacial adhesion of silicon rubber, and preparation process is simple, and production cost is low, applied widely.
Specific embodiment
