Description
Technical field
The present invention relates to silicon rubber technical field more particularly to a kind of digital keys methyl vinyl silicone rubbers.
Background technology
Silicon rubber is one of most important kind in special synthetic rubber, it is that main chain is the Si-O atoms being alternately arranged,
Side group is the siloxane chain shaped polymer of organic group, can become rubber-like elastic body by crosslinking.Silicon rubber has excellent
Heat resistance, cold resistance, insulating properties, highly-breathable and physiological inertia etc., it is incomparable for other high-molecular organic materials
And replacement, it is widely used in the digital keys of high end equipment.
But the continuous development of the digital keys with high end equipment, the requirement for material is higher and higher, particularly pair
The demand for being applied to silastic material of the extreme condition with wear-resisting, resistance to hot function in some is growing, it would be highly desirable to solve.
The content of the invention
Technical problems based on background technology, the present invention propose a kind of digital keys methyl ethylene silicon rubber
Glue, wear-resisting property is extremely excellent, and heat resistance is fabulous, can meet its application on digital keys product, be particularly suited for
The occasion more demanding to hot environment.
A kind of digital keys methyl vinyl silicone rubber proposed by the present invention, raw material include by weight：Low ethylene

The present invention using fluorine silicone rubber and low vinyl content methyl vinyl silicone rubber as rubber substrate, long-chain with it is short
Chain acts synergistically, and not only intermolecular force is big, but also has fabulous demoulding effect, while of low cost；And gas phase hard charcoal
It is black to be dispersed in rubber substrate, not only the additive amount of rubber substrate can be reduced indirectly, but also can further improve the comprehensive of the present invention
Close performance；Multi-walled carbon nanotube, Silica Nanotube compounding, multi-walled carbon nanotube intramolecular contain the stronger pi bond of delocalization,
Defect is easily formed between layer by layer, and Silica Nanotube is tubular structure, while also there are spherical silicon dioxide particle, it is more
Wall carbon nano tube, Silica Nanotube and rubber substrate compound tense, not only disperse to be formed fabulous, but also rubber molecule can enter
Rejected region is in tubular structure, playing certain enhancing and cross-linking effect, further in methyl trifluoro propyl silicone oil with containing cyanogen
Under the action of silicone oil, effect of impregnation is good, and effectively reduce the present invention hardness, intersect each other it is strong, through peroxidating two
After benzoyl crosslinking, wear-resisting property of the invention is extremely excellent, simultaneously because forming substantial amounts of passage of heat in rubber substrate, makes
Heat resistance of the present invention is fabulous, can meet its application on digital keys product, particularly suitable for more demanding to hot environment
Occasion.The tear-resistant intensity of the present invention is up to 26kN/m, and tensile strength is up to 15Mpa, and for -65 DEG C~400 DEG C, the service life can
