Description
Technical field
The present invention relates to anti-flaming smoke-inhibiting agent technical field, be specifically related to a kind of Red copper oxide hydridization Graphene anti-flaming smoke-inhibiting agent
And preparation method thereof.
Background technology
Since 21 century, along with developing rapidly of national economy, organic polymer material in people's daily life and
The medium every field of the development of the national economy is all widely used, and organic polymer material is to the development of the life of the mankind with society
All bring huge facility.But, most of organic polymer material is all readily ignited and deflagrate, and produces
Substantial amounts of calory burning and toxic gas, also bring huge threat to the most undoubtedly human lives, therefore improves organic poly-
The combustibility of laminate material is increasingly paid attention to by researcher.
Graphene (GNS) is a kind of bi-dimensional cellular shape planar structure tightly packed by monolayer carbon atom, and it has
Bigger surface area and excellent electricity, optics, mechanics and thermal property, therefore suffered from the extensive of various fields researcher
Pay close attention to.At present, Graphene is at the energy and electronic equipment, chemical sensor, pharmaceutical carrier, catalyst and transparent conductive material etc.
Field is widely used, and it has been investigated that, it has huge in terms of improving the fire resistance of polymer equally

Rice sheet (guide number S) can give the anti-flammability that epoxy resin is excellent, add the GNS of 5wt% can make the LOI value of epoxy resin from
15.7% increases to 21.4%, and total heat release can be from 33.4kJ/m2It is reduced to 27.8kJ/m2.It practice, Graphene
The graphene sheet layer mainly due to bigger serface that promotes of composite polymeric materials fire resistance can be effective as one
Physical barriers, thus the energy between gas phase and condensed phase and the transmission of material during suppressing polymer combustion.
But, owing to there is stronger Van der Waals force between graphene sheet layer, therefore Graphene is in preparation dry run
Easily being packed together between its lamella, when causing Graphene to be used alone, its flame retarding efficiency is poor, therefore can not suppress well
The burning of polymer.Additionally, the experimental results shows, Graphene is more weak to the smoke suppressing of polymer, it is impossible to effectively suppress
The release of cigarette, it is therefore necessary to Graphene is carried out surface modification to improve its flame retarding efficiency in polymeric matrix and to press down cigarette
Performance.
Red copper oxide (Cu2O) as tradition smoke suppressant, by reduction coupling mechanism, it can promote that polymer is burned
Journey is formed more layer of charcoal, the smoke suppressing improving polymer is had the highest efficiency.And as a kind of two-dimension single layer material,
Graphene is the ideal carrier that metal-oxide is applied to catalytic field, therefore, studies Red copper oxide-graphene hybrid material,
This is significant to the flame retarding and smoke suppressing properties improving polymer.
