A kind of underwater anticorrosive paint of graphene composite Nano alloy, including component A and B component, component A and B component matter
Amount is than being 4:(1-2)；
Wherein, component A is by including that the raw material of following parts by weight is made:
B component is by including that the raw material of following parts by weight is made:
20-25 parts of curing agent,
0-1 parts of thixotropic agent, and do not include 0；
0-1 parts of coupling agent, and do not include 0.
Further, the epoxide number of the epoxy resin 1 is 0.41-0.47, and the epoxide number of the epoxy resin 2 is 0.48-
0.54, the epoxide number of the epoxy resin 3 is 0.18-0.22.
Further, the graphene composite Nano alloy base-material is prepared by the method included the following steps:
A, by graphene powder, metal alloy powder, epoxy resin 1, coupling agent, acetone 20:20:59.6 in mass ratio:
The first ultrasonic mixing in closed ultrasonic stirrer of the ratio of 0.4:100；
B, the mixed liquor that the step a is obtained is imported in nano-level grinder and is ground；
C, the step b is obtained into the abjection of the acetone in mixed liquor to get graphene composite Nano alloy base-material.
Further, metal alloy powder is silver, zirconium, the two or more mixtures in titanium, ultrasonic mixing in the step a
6 hours；
The fineness ground in the step b is less than or equal to 20 μm；
The condition for deviating from acetone in the step c is 60 DEG C and vacuumizes 60min to -0.8Pa.
Further, coupling agent is GF9 in the step a.
Further, the partial size of the graphene powder is in 5-30nm.
Further, the silver, zirconium, titanium are mixed by the mass ratio of 1:1:(2-3).
Further, in component A, the toughener is the mixture of one or both of DOP or DBP；
The nanometer base-material is the mixture of one or both of nano-titanium dioxide or nano zine oxide；
The filler is the mixture of one or more of kaolin, blanc fixe, mica powder or trbasic zinc phosphate；
The pigment is one of titanium dioxide or iron oxide black；
The thixotropic agent is the mixture of one or more of white carbon black, gas-phase silica or organobentonite.
Further, the DOP and DBP is mixed by the mass ratio of 1:(2-5)；
The nano-titanium dioxide is with nano zine oxide by 1:(1-2) mass ratio mix；
The kaolin, blanc fixe, mica powder, trbasic zinc phosphate are mixed by the mass ratio of 1:5:1.5:1；
The white carbon black, gas-phase silica, organobentonite are mixed by the mass ratio of 1:3:1.
Further, the function additive is coupling agent KH550: dispersant B YK104: defoaming agent BYK054 in mass ratio 2:
1:1 is mixed to get.
Further, in B component, the curing agent is one or both of JA-1S and MA 1:(1-4 in mass ratio) it is mixed
It closes；The thixotropic agent is TS720；The coupling agent is GF95.
The preparation method that the present invention also provides a kind of such as the above-mentioned underwater anticorrosive paint of graphene composite Nano alloy,
This method comprises the following steps:
A, component A is prepared:
(1) will all epoxy resin heating mixing in formula, after to be cooled to room temperature spare；
(2) other materials is successively put into epoxy resin liquid according to formula sequence, using under blender vacuum state
Disperse up to component A；
B, B component is prepared:
Three kinds of components of formula are stirred and are dispersed to uniformly without particle；
C, component A is mixed by formula rate and the anticorrosive paint can be obtained in B component.
Further, in the component A preparation method, the step (1) is warming up to 90-100 DEG C, mixes 1 hour；The step
