Abstract
The invention discloses a nanometer modified epoxy anti-corrosion paint prepared from the following raw materials in parts by weight: 30 parts of epoxy resin, 0.8 part of coupling agent, 21 parts of pigment, 21 parts of filler, 13 parts of nanometer silicon and 10 parts of solvent, wherein the epoxy resin comprises E20 epoxy resin, and the coupling agent comprises a silane coupling agent. The nanometer silicon as the raw material can be automatically filled in a generated hole in a film forming process to finally play compact and impermeable roles and improve the impermeability to water and other media, so that the anti-corrosion property of the whole paint film is improved, and an unexpected technical effect is achieved.
Description
Technical field
The present invention relates to antifouling paste, be specifically related to a kind of nanometer modified epoxy antifouling paste.
Background technology
At present, epoxy anticorrosive paint is applicable to the Waterproofing/oilproofing chemical-resistant reagent of steel equipment and pipeline, do the use of protection bottoming, also can be used as aluminium alloy, cementitious substrate bottoming or bottom surface unification protection.But existing epoxy anticorrosive paint antirust ability is strong, easily produce precipitation, construction process requirement is high.If construction wrong, rust-stabilising pigment is not fully utilized, and a little less than the anodic protection effect, paint film is prone to and returns the rust phenomenon, affects the long-term antiseptic property of epoxy anticorrosive paint.How improving the long-term antiseptic property of epoxy anticorrosive paint, is the direction that epoxy anticorrosive paint is made great efforts.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of nanometer modified epoxy antifouling paste, its paint film densification, and shielding is good, and antiseptic property is superior and the anti-ability of soaking into is strong, thereby eliminates defect in the above-mentioned background technology.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of nanometer modified epoxy antifouling paste comprises that the raw material of following weight part is prepared from: epoxy resin 30, coupling agent 0.8, pigment 21, filler 21, nano-silicon 13, solvent 10; Described epoxy resin comprises E20 epoxy resin; Described coupling agent comprises the polysilane coupling agent.
As a kind of improvement, described pigment comprises titanium dioxide, carbon black or iron oxide red.
As a kind of improvement, described filler comprises at least one of process white, talcum powder and water-ground limestone.
As a kind of improvement, described solvent comprises at least one of dimethylbenzene, propyl carbinol.
As a kind of improvement, described nano-silicon comprises the nano silica fume of particle diameter 3-4 nanometer.
The present invention is prepared as follows step:
S1, obtain the E20 epoxy resin, polysilane coupling agent, pigment, filler, nano-silicon and the solvent that weigh by weight, the 1/2 E20 epoxy resin weighed, the polysilane coupling agent weighed, pigment and filler are mixed, and high speed dispersion 25-35 minute, be uniformly dispersed, obtain just mill base;
S2, by the first mill base obtained in step S1, utilize sand mill to be ground to fineness 20-40um, obtain thick mill base;
S3, by the thick mill base obtained in step S2, add the residue 1/2 E20 epoxy resin weighed, the nano-silicon weighed and solvent high-speed stirring 15-25 minute, the indexs such as viscosity, fineness, dryness of adjusting product are product.
In step S1, during high speed dispersion, stirring velocity is 1000-1500 rev/min.
In step S3, during high-speed stirring, stirring velocity is 1000-1500 rev/min.
Owing to having 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: be at first to have selected effectively to improve the fine and close not raw material of antifouling paste film forming, 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 because the modified epoxy paint is certain to produce hole in film process, cause dense form to reduce, the technician is when improving its performance, when unexpected discovery adds nano-silicon in raw material, in film process, nano-silicon meeting automatic filling, to the hole produced, finally plays fine and close not saturating effect, improves the impermeabilisation power to water and other media, thereby improve whole paint film antiseptic property, this is that those skilled in the art are beyong contemplation; Secondly, the invention provides the proportioning of each raw material, the proportioning value draws through a large amount of experiment screenings repeatedly of technician, especially the raw material of selecting in conjunction with the present invention, 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, the consumption of polysilane coupling agent for example, if consumption is lower than 0.5 weight part, product easily precipitates, if consumption affects sticking power higher than 1 weight part; The consumption of nano-silicon is lower than 10 weight parts, and antiseptic property is not obvious, if 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 provided in the present invention, just mill base utilizes sand mill to be ground to fineness 20-40um, adopt the nano silica fume that particle diameter is the 3-4 nanometer simultaneously, and adopt the speed of 1000-1500 rev/min disperseed and stir, 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.
The nanometer modified epoxy antifouling paste prepared according to raw material provided by the invention, proportioning, there is 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 anti-corrosion primer, after the remodeling epoxy anticorrosion primer, by standard making sheet, be salt spray resistance and water tolerance contrast experiment, result, as following table, finds out that from result nanometer modified epoxy antifouling paste antiseptic property is better than common epoxy anticorrosive paint.
