As a kind of improvement, said solvent comprises at least a of YLENE, propyl carbinol.
As a kind of improvement, said nano-silicon comprises the nano silica fume of particle diameter 3-4 nanometer.
The present invention is prepared as follows step:
S1, obtain the epoxy resin, coupling agent, pigment, filler, nano-silicon and the solvent that weigh by weight; 1/2 epoxy resin, the coupling agent that weighs, pigment and the filler that weigh mixed; And high speed dispersion 25-35 minute, be uniformly dispersed, obtain mill base just;
S2, with the first mill base that obtains among the step S1, utilize sand mill to be ground to fineness 20-40um, obtain thick mill base;
S3, with the thick mill base that obtains among the step S2, added the epoxy resin that residue 1/2 weighs, the nano-silicon that weighs and solvent high-speed stirring 15-25 minute, the indexs such as viscosity, fineness, dryness of adjusting product are product.
Among the step S1, during high speed dispersion, stirring velocity is 1000-1500 rev/min.
Among the step S3, during high-speed stirring, stirring velocity is 1000-1500 rev/min.
Owing to adopted technique scheme, the invention has the beneficial effects as follows:
A kind of nanometer modified epoxy antifouling paste provided by the invention; Those skilled in the art have done a large amount of explorations: at first be to have selected effectively to improve the fine and close inadequately raw material of antifouling paste film forming; The antiseptic property and the impermeabilisation ability of epoxy anticorrosive paint have effectively been increased; Nanometer modified epoxy antifouling paste provided by the invention, wherein heavy flakey rust-stabilising pigment, zinc powder are evenly distributed in paint film, and physicals is even; And, causing dense form to reduce because the modified epoxy lacquer is certain to produce the hole in film process, the technician is when improving its performance; The unexpected discovery when adding nano-silicon in the raw material; Nano-silicon can be filled in the hole of generation automatically in the film process, finally plays fine and close effect of not passing through, and improves the impermeabilisation power to water and other media; Thereby improve whole paint film antiseptic property, this is those skilled in the art's beyong contemplations; Secondly, the invention provides each proportion of raw materials, the proportioning value draws through a large amount of experiment screenings repeatedly of technician; Especially the raw material that combines the present invention to select for use can make the paint film densification of nanometer modified epoxy antifouling paste, the advantage that shielding is good, antiseptic property is superior and the anti-ability of soaking into is strong perform to the best, has very high creativeness; For example: the consumption of coupling agent; If consumption is lower than 0.5 weight part, then product is prone to deposition, if consumption is higher than 1 weight part and then influences sticking power; The consumption of nano-silicon is lower than 10 weight parts, and then antiseptic property is not obvious, if be higher than 15 weight parts, the antiseptic property state that tends towards stability can cause the waste of nano-silicon.
In addition, in the preparation process that provides among the present invention, first mill base utilizes sand mill to be ground to fineness 20-40um; Adopting particle diameter simultaneously is the nano silica fume of 3-4 nanometer; And the speed that adopts 1000-1500 rev/min disperses and stirs, and under these processing condition, nano-silicon is best to the filling effect in hole; Make the film forming of nanometer modified epoxy antifouling paste the finest and close, it is best that overall performance reaches.
Nanometer modified epoxy antifouling paste according to raw material provided by the invention, proportioning preparation has excellent preservative property and impermeabilisation ability, the epoxy zinc rich primer that test makes; The modified epoxy zinc rich primer, the iron oxide red epoxy anticorrosion primer is behind the remodeling epoxy anticorrosion primer; By standard making sheet; Be salt spray resistance and water tolerance contrast experiment, result such as following table find out that from the result nanometer modified epoxy antifouling paste antiseptic property is superior to common epoxy anticorrosive paint.
