Examples
Example 1
The anticorrosive finish paint comprises the following components in parts by weight as shown in Table 1, and is prepared by the following steps:
s1, mixing the novolac epoxy resin and the polyamide resin at 200 ℃ at 1000r/min for 30 min;
s2, adding a film-forming aid, a defoaming agent and the silicone oil/asphalt composite emulsion, and mixing at 140 ℃ at 2500r/min for 10min to obtain the anticorrosive finish paint;
wherein the polyamide resin is polyamide 115; the film-forming auxiliary agent is propylene glycol butyl ether; the defoaming agent is polyethylene glycol; a silicone oil/asphalt composite emulsion was prepared by preparation example 1.
Examples 2 to 6
An anticorrosive topcoat paint, which is different from example 1 in that each component and the corresponding weight thereof are shown in table 1.
TABLE 1 Components and weights (kg) thereof in examples 1-6
Comparative example 1
An anticorrosive finish paint is different from the anticorrosive finish paint in the embodiment 1 in that the anticorrosive finish paint is identical to the anticorrosive finish paint in the embodiment 1 except that the components do not contain the silicone oil/asphalt composite emulsion.
The anticorrosive topcoats prepared in examples 1 to 6 and comparative example 1 were extracted, and adhesion, acid resistance and alkali resistance were measured according to the above measurement procedures and measurement standards, and the results of the measurements were averaged and recorded in the following table.
As can be seen from the table above, the anticorrosive finish paint prepared in examples 1-6 has strong adhesion, up to 8.3-9.2MPa, and has performance standard of more than 8.0 MPa; the acid resistance is excellent and is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sulfuric acid solution for 168 hours; the alkali resistance is excellent and is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sodium hydroxide solution for 168 hours;
therefore, the anticorrosive finish paint prepared from the components according to the proportion has excellent adhesive force and corrosion resistance, and is not easy to peel, crack or fall off after being cured and formed into a film.
In particular, the anticorrosive finish paint prepared in the embodiment 4 has strong adhesive force which is as high as 9.2MPa and is far greater than the performance standard of 8.0 MPa; the acid resistance is strong, and the coating is free from pathological coating phenomenon in 20% sulfuric acid solution for 168 hours; the alkali resistance is strong, and the pathological film coating phenomenon is avoided in 20% sodium hydroxide solution for 168 hours;
it can be seen that example 4 is the best example, and the anticorrosive finish paint prepared by the components has the best performance, wherein in examples 5-6, although the acid resistance and alkali resistance are equal to those of example 4, the adhesion is reduced, and the practical use of the anticorrosive paint is not facilitated.
It can be seen from the above table that, compared with example 1, in comparative example 1, because the components do not contain the silicone oil/asphalt composite emulsion, the performances can also meet the basic use standard, but the adhesion force is only 8.1 MPa; the acid resistance is weak, and the coating is only in a 10% sulfuric acid solution for 168 hours, so that the pathological coating phenomenon is avoided; the alkali resistance is weak, and the film is only in a 10% sodium hydroxide solution for 168 hours without pathological film coating phenomenon;
the addition of the silicone oil/asphalt composite emulsion is favorable for improving the adhesiveness and the crosslinking density of the finish paint, so that the finish paint can have better anticorrosion and protective properties after being cured into a film, and is not easy to peel, crack or fall off.
The reason may be that the silicone oil contains more active functional groups, which can be respectively combined with C ═ C double bonds, carboxyl groups, hydroxyl groups and other groups in the coal tar pitch, the epoxy resin and the fluorocarbon resin to strengthen the connection relationship among the multiple components, so as to form a three-dimensional cross-linked network structure with a complex structure, and can also be used as a dispersant and a lubricant to fully fill the nano inorganic filler in the three-dimensional cross-linked network and form a compact anticorrosive coating, so as to realize the anticorrosive protection effect of the finish paint.
In conclusion, the silicone oil/asphalt composite emulsion prepared by blending and modifying the silicone oil, the coal tar pitch, the fluorocarbon resin and the nano inorganic filler can obviously improve the water resistance and the cohesiveness of the coating after being doped into an anticorrosive finish paint system, and further has better anticorrosive protection performance after the coating is cured into a film;
the solvent-free epoxy anticorrosive finish paint system has high bonding strength with a substrate to be protected, has low shrinkage rate during curing film forming, and is not easy to generate pores, and then the finish paint is not easy to peel, crack or fall off after being cured into a film.

As can be seen from the table above, the anticorrosive finish paint prepared in the embodiment 1 and the embodiments 7 to 9 has strong adhesive force which is as high as 8.3 to 9.2MPa and is greater than the performance standard of 8.0 MPa; the acid resistance is excellent and is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sulfuric acid solution for 168 hours; the paint has excellent alkali resistance which is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sodium hydroxide solution for 168 hours, and the silicone oil/asphalt composite emulsion prepared by the process can improve the performance of the anticorrosive finish paint.
In particular, the anticorrosive finish paint prepared in the examples 1 and 7-8 has strong adhesive force which is as high as 8.6-9.0MPa and is far greater than the performance standard of 8.0 MPa; the acid resistance is strong, and the coating is free from pathological coating phenomenon in 15% sulfuric acid solution for 168 hours; the alkali resistance is strong, the coating phenomenon is not generated in 15% sodium hydroxide solution for 168 hours, and the parameter conditions in preparation examples 2-3 are shown to be better processes.
In conclusion, the silicone oil/asphalt composite emulsion prepared by mixing the components by the step method has relatively stable and uniform performance, and can effectively improve the adhesiveness and the crosslinking density of the finish paint, thereby ensuring the anti-corrosion and protective performance of the finish paint.

Comparative example 2
An anticorrosive finish paint is different from the anticorrosive finish paint in example 1 in that the conditions are the same as those in example 1 except that fluorocarbon resin is not contained in the silicone oil/asphalt composite emulsion.
The anticorrosive topcoats prepared in examples 10 to 13 and comparative example 2 were extracted, and adhesion, acid resistance and alkali resistance were measured according to the above measurement procedures and measurement standards, and the results of the measurements were averaged and recorded in the following table.
As can be seen from the table above, the anticorrosive finish paint prepared in the embodiment 1 and the embodiments 10 to 13 has strong adhesive force which is as high as 8.2 to 8.6MPa and is greater than the performance standard of 8.0 MPa; the acid resistance is excellent and is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sulfuric acid solution for 168 hours; the paint has excellent alkali resistance which is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sodium hydroxide solution for 168 hours, and the performance of the anticorrosive finish paint can be effectively improved by the silicone oil/asphalt composite emulsion prepared from the silicone oil and the fluorocarbon resin according to the proportion.
Further, examples 10 to 12 are preferred examples, and the adhesion was small and the reduction in the degree of adhesion was 8.5 MPa; but the corrosion resistance is obviously enhanced, and no pathological film coating phenomenon exists in 20 percent sulfuric acid solution for 168 hours; in 20% sodium hydroxide solution for 168 hours, no pathological film coating phenomenon exists, and the improvement of the performance of the anticorrosive finish paint is more remarkable when the weight ratio of the silicone oil to the fluorocarbon resin is 1 (0.1-0.2);
and as can be seen from the above table, although the corrosion resistance of the finish paint can be effectively guaranteed by adding excessive fluorocarbon resin, the flexibility, elasticity and adhesive force of the coating are reduced, which is not beneficial to the practical use of the finish paint.
Compared with the example 1, the adhesion of the comparative example 2 is improved to 8.8MPa because the silicone oil/asphalt composite emulsion does not contain fluorocarbon resin, but the corrosion resistance is correspondingly reduced, and the coating can only be carried out in a 10% sulfuric acid solution for 168 hours without pathological coating phenomenon; the coating is carried out for 168 hours in a 10% sodium hydroxide solution, and no pathological coating phenomenon exists;
it can be seen that the three components in the silicone oil/asphalt composite emulsion have a certain compounding effect, and the improvement of the anti-corrosion performance of the anti-corrosion finish paint is reduced after the fluorocarbon resin is lacked.
In conclusion, the silicone oil and the fluorocarbon resin in the proportion have excellent compounding effect, and can form a stable prepolymer through crosslinking of bonding relations such as fluorine-carbon bonds, facilitate further crosslinking combination of the prepolymer and other components, and endow the finish paint with excellent corrosion resistance and weather resistance through the characteristics of the fluorocarbon resin.

As can be seen from the table above, the anticorrosive finish paint prepared in the embodiment 1 and the embodiments 14 to 17 has strong adhesive force which is as high as 8.6 to 9.2MPa and is greater than the performance standard of 8.0 MPa; the acid resistance is excellent and is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sulfuric acid solution for 168 hours; the paint has excellent alkali resistance which is higher than the performance standard, namely, no pathological film coating phenomenon exists in a 10% sodium hydroxide solution for 168 hours, and the performance of the anticorrosive finish paint can be effectively improved by the silicone oil/asphalt composite emulsion prepared from the silicone oil and the fluorocarbon resin according to the proportion.
Further, examples 14 to 16 are preferred examples, and the adhesion was small and the reduction in the level was 9.1 to 9.2 MPa; but the corrosion resistance is obviously enhanced, and no pathological film coating phenomenon exists in 20 percent sulfuric acid solution for 168 hours; when 20% sodium hydroxide solution is used for 168 hours, no pathological film coating phenomenon exists, and the emulsion premix, the coal tar pitch and the nano inorganic filler are mixed according to the weight ratio of 1 (0.2-0.3) to 0.3-0.5, so that the anti-corrosion finishing paint has remarkable improvement on the performance;
as can also be seen from the above table, in comparative example 3, compared with example 1, since the silicone oil/asphalt composite emulsion does not contain the nano inorganic filler, the adhesion force is basically even and is 8.7MPa, but the corrosion resistance is correspondingly reduced, and the coating can only be carried out in a 10% sulfuric acid solution for 168 hours without pathological coating phenomenon; the coating is carried out for 168 hours in a 10% sodium hydroxide solution, and no pathological coating phenomenon exists;
it can be seen that the three components in the silicone oil/asphalt composite emulsion have a certain compounding effect, and the improvement of the anti-corrosion performance of the anti-corrosion finish paint is reduced after the nano inorganic filler is lacked.
In conclusion, the coal tar pitch and the nano inorganic filler in the proportion have a better matching relationship with the emulsion premix, not only can further enhance the complexity of a three-dimensional cross-linked network structure, but also can form a compact anticorrosive coating through compounding of the coal tar pitch, the nano inorganic filler and the emulsion premix, and the nano inorganic filler can be filled and combined in the formed cross-linked network, so that the compactness of a coating system is enhanced, and the bonding performance of the coating is not easily influenced.
