Comparative example 1
The difference of this comparative example and embodiment 1 is only that, does not include graphene slurry, remaining group in this comparative example B component
It is point same as Example 1 that epoxy glass squama antiseptic paint is prepared.
Epoxy glass squama antiseptic paint prepared by embodiment 1 and comparative example 1 carries out seawater immersion test, when recording identical
Between the corrosion condition put, be divided into early period, mid-term and later period.Concrete outcome is as shown in figs 1 to 6.Wherein, Fig. 1, Fig. 2 and Fig. 3 points
Not Wei comparative example 1 prepare epoxy glass squama antiseptic paint impregnate early period, mid-term and later period erosion profile figure, Fig. 4, Fig. 5 and
Fig. 6 is early period, mid-term and the later period erosion profile figure that epoxy glass squama antiseptic paint prepared by embodiment 1 impregnates, and passes through observation
Comparison it is found that embodiment 1 erosion profile of the coating in different immersion periods, impregnate early period and mid-term do not generate more apparent corruption
Erosion, surface remain unchanged smooth corrosion-free product.The immersion later period produces apparent yellow corrosion product, comparative example on two kinds of coatings
The corroded area on coating that 1 epoxy glass squama antiseptic paint is formed is larger, also with some black in yellow corrosion product,
It is relatively corrosive than more serious.And the corroded area on the coating of epoxy glass squama antiseptic paint prepared by embodiment 1 is smaller, it is resistance to
Corrosivity is preferable.
Epoxy glass squama antiseptic paint prepared by comparative example 1 carries out same carry out ac impedance spectroscopy survey in the seawater
Examination, soaking time is respectively 5h, and for 24 hours, 72h, 120h, 360h, 432h, 528h, concrete outcome is as shown in table 2:
Table 2

By charge transfer resistance RrVariation it is found that addition graphene glass flake coatings RrGreater than not adding graphite
The R of the glass flake coatings of alkener, illustrate that the coating corrosion resistance for adding graphene can be more preferable, the impedance of 5h to 120h in two tables
Value reduce, analysis the reason is that coating damage rate increasing cause corrosion accelerate, and 360h to 528h impedance value increase, analyze the reason is that
The corrosion product generated before is adsorbed on coating surface layer, blocks damaged mouth, plays protective effect, reduces corrosion.
Pass through the charge transfer resistance R in embodiment 1 and comparative example 1rComparison is it is found that R in embodiment 1rValue it is bigger, resist
Corrosive effect is more excellent.
