Experimental example 1
The performance for the composite material that the embodiment of the present invention, comparative example are prepared is compared.Longitudinal tensile strength and
Modulus test is measured according to method specified in GB/T 1447-2005, and buckling strength and modulus test are according to GB/T
Method specified in 1449-2005 is measured, and the test of short beam shear strength in ASTM D2344/D2344M-13 according to advising
Fixed method is tested, and the test of notch impact strength is measured according to method specified in GB/T 1451-2005.Tool
Body testing result is as shown in table 3 below.
3 the performance test results of table
From experimental result as can be seen that relative to conventional without the fiber-reinforced polymer-matrix composite wood for introducing graphene
Material, the comprehensive mechanical property of resulting product are significantly improved.Firstly, either bending strength or tensile strength are all because of stone
The introducing of black alkene and occur slightly improving, while more valuable is this expression toughness of material of the notch impact strength of material
Index also with graphene introducing and greatly improve, the toughness of display material is enhanced.So through the invention
The polymer matrix composite of preparation method preparation just realizes rigidity-toughness balanced to a certain extent, to be conducive to expand such
The application field of material.
In addition it is worth noting that, the key of graphene activeness and quietness is that it disperses in a polymer matrix, therefore one
As use condition under need to introduce surface active agent composition, such as neopelex, Silane coupling agent KH550 etc..And
On the one hand surfactant that the propylene esters polymer used in the present invention disperses in resin adhesive liquid as help graphene,
The component can also play the role of release agent in material preparation process simultaneously, and it is (opposite to show as seldom release agent additive amount
It is 0.5 mass parts in resin) good stripping result can be obtained.This double action, which has taken into account, ensure that the equal of graphene
The process stabilizing of even dispersion and product preparation, therefore be also the present invention important summary of the invention and innovative point.Pass through comparative example 10-
13 as can be seen that the simple graphene that is added cannot play humidification, this is because the agglomeration traits of graphene result in
The disappearance of activeness and quietness effect, and the relative scale of graphene and acrylic polymer is also particularly significant, acrylate
Quasi polymer addition is very few, can not reach good graphene dispersion effect, so that it is not apparent to show as product properties
It improves.Mechanism is mutually matched this also illustrates graphene and dispersing agent (acrylic polymer).
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, it can be combined in any appropriate way.In order to avoid unnecessary repetition, the present invention to it is various can
No further explanation will be given for the combination of energy.
Although illustrate and describing the present invention with specific embodiment, it will be appreciated that without departing substantially from of the invention
Many other change and modification can be made in the case where spirit and scope.It is, therefore, intended that in the following claims
Including belonging to all such changes and modifications in the scope of the invention.
