Embodiment 1 and comparative example 1 are the influences for verifying graphene oxide and modified graphene oxide to damping,
The modified dispersion be conducive in the base of graphene oxide, reduces the generation of reunion, and the compatibility of enhancing and matrix is modified
Damping is basically unchanged, and fissipation factor is 1 or so, but low temperature range damping property increases.And by attached drawing 2 in 5um
Electricity under the microscope can significantly find out that the fold of modified graphene oxide significantly reduces.The reason is that modified graphene oxide
Compatibility is more preferable in polymer matrix macromolecular chain, plays the role of " lubricating ", so to show as damping fin elasticity preferable, soft for print
It spends higher, glass transition temperature to decrease, is conducive to construction.
Pass through embodiment 2 and the research discovery of comparative example 2.The effect of smoke density is carried out due to cost considerations first
The compounding of test, molybdenum system column fire retardant and zinc borate has biggish improvement to maximum smoke density and smoke density grade, and oxygen refers to
Number, smoke density grade, maximum smoke density are up to standard, and modified graphene oxide (MGO) is because reduce surface tension, with
Matrix it is compatible much better, so reducing to the effect of smoke density much better, oxygen index (OI) can achieve 32, smoke density grade
Little with the variation of maximum smoke density, in addition modified graphene oxide (MGO) also has facilitation to damping, changes relative to nothing
The peak value of property graphene oxide damping loss factor improves 0.15 or so, but molybdenum trioxide fire retardant series has inhibition to damping
Effect, makes fissipation factor damping peak reduce 0.2 or so, in controlled range.Fire protecting performance has been carried out into one in embodiment 3
Step research, compounds synergistic with nitrogen phosphorus dilatancy app by graphene oxide, enhances layer of charcoal in terms of acid source and charcoal source, pass through
Shown in attached drawing 4 and attached drawing 5, being formed by layer of charcoal after further improving does not have fracture phenomena, compact and complete, effectively prevents flame
Further to propagate, attached drawing 6 is the entire heat release of 3 olefinic carbon damping material combustion process of comparative example 2 and comparative example
Rate curve, it has been found that there is the active combustion time after layer of charcoal barrier to be reduced to by the 40s-550s in comparative example 2
31s-375s in comparative example 3, from showing total cigarette rate of release by the 39.4MJ/m in comparative example 2 in attached drawing 7
It has been reduced to 28.4MJ/m, and total cigarette rate of release is the key that determine that flame extends index, flame Drawing rate is being prevented fires
Very important effect is played in the disaster relief, is obviously improved so fire protecting performance has before relatively improving.Attached drawing 8 is that entire cigarette is close
