Description
Technical Field
The invention relates to the technical field of galvanized sheet surface treatment, in particular to a primer for a single-component galvanized sheet and a preparation method thereof.
Background
The galvanized sheet is used as a sheet material with better strength and flexibility, and is widely applied to the fields of movable board houses, living boxes and the like. Because the galvanized sheet is provided with the galvanized layer, the galvanized sheet has better anti-corrosion performance, but a layer of paint is generally required to be sprayed on a movable house for attractive appearance, and the paint is required to have better adhesive force to the galvanized layer, excellent weather resistance and certain water resistance. The adhesion of the coating to the galvanized layer, particularly the adhesion of the coating after soaking water, is particularly critical, and the coating is easy to fall off due to the lack of the adhesion, so that the service life of the board room is directly affected.
However, since materials such as galvanized sheet, aluminum sheet and glass are difficult to adhere, it is generally necessary to use an adhesion promoter to enhance the adhesion effect of the coating film on such a substrate.

Pull-apart adhesion test
Test instrument: BGD 500 digital display pull development adhesion tester (Guangzhou standard reach laboratory instruments Co., ltd.)
The testing method comprises the following steps: GB/T5210-2006 paint and varnish adhesion test by pull-off method (idt iso 4624-2002)
A bottom plate: the specification of the sandblasted steel plate is 150X70X (3-5) mm
According to the specification of GB/T5210-2006, a test column with the diameter of 20mm is adopted, and an upper test column and a lower test column are coaxially butted with a sample plate for testing.
The pull-apart adhesion test results are shown in the following table:
TABLE 5
Analysis of results:
It can be seen from examples 1 and 4 that the formulation of example 1 has a certain improvement in adhesion relative to example 4 when the formulation of example 1 is used, and thus, the improvement effect of the formulation of example 1 on the adhesion of the primer for one-component galvanized sheet is more remarkable than that of example 4;
It can be seen from examples 1 and comparative examples 1 to 3 that, although the semi-finished product B contains a large amount of zinc epoxy phosphate, the semi-finished product C and the semi-finished product D contain a large amount of PVB resin, when zinc epoxy phosphate is used instead of the semi-finished product B and epoxy resin is used instead of the semi-finished product C and the semi-finished product D, the adhesion ability of the primer is reduced to different extents, so that it is considered that the factors for improving the adhesion of the primer are not only the zinc epoxy phosphate in the semi-finished product B, the PVB resin in the semi-finished product C and the PVB resin in the semi-finished product D, but also the other substances in the semi-finished product B, the semi-finished product C and the semi-finished product D, and the adhesion ability of the primer is more likely to be improved as a result of synergy between the zinc epoxy phosphate in the semi-finished product B, the PVB resin in the semi-finished product C and the other substances in the semi-finished product B and the semi-finished product D;
As can be seen from examples 1 and 4 to 7, when the n-butanol or the semi-finished product C is added not twice but once, the adhesion of the primer is reduced to a small extent, and it is presumed that the reason for this is that the n-butanol or the semi-finished product C cannot be sufficiently reacted or mixed with other raw materials by one addition, and thus the effect of the n-butanol or the semi-finished product C cannot be sufficiently exerted;
as can be seen from example 1 and comparative examples 8 to 10, the adhesion ability of the primer was significantly reduced when Desettle p, afcon a2020, afcona4010 were absent from the raw materials of the primer, and it can be seen that Desettle p, afcon a2020, afcona4010 described above are indispensable components in the primer for one-component galvanized sheet;
It can be seen from example 1 and comparative examples 11 to 13 that the adhesion ability of the primer for one-component galvanized sheet was reduced to a different extent when Desettle p, afcon a 2020, afcona4010 were replaced with canfair p, BYK052, and DISPERBYK-163, and it was found that Desettle p, afcon a 2020, afcona4010 were not replaced in the raw materials of the primer for one-component galvanized sheet.

The water resistance effect of the examples is good, and the data are shown in the following table as the water resistance effect is good, general and poor according to the grade evaluation:
TABLE 6
Analysis of results:
It can be seen from examples 1 and comparative examples 1 to 3 that, although the semi-finished product B contains a large amount of zinc epoxy phosphate, the semi-finished product C and the semi-finished product D contain a large amount of PVB resin, when zinc epoxy phosphate is used instead of the semi-finished product B and epoxy resin is used instead of the semi-finished product C and the semi-finished product D, the water resistance of the primer is reduced to a different extent, and in combination with fig. 5, the water stain residue in comparative examples 1 to 3 is significantly more serious than that in example 1, so that it is considered that the factor for improving the water resistance of the primer is not only due to the zinc epoxy phosphate in the semi-finished product B, the semi-finished product C and the PVB resin in the semi-finished product D, but also due to other substances in the semi-finished product B, the semi-finished product C and the semi-finished product D, but the improvement of the water resistance of the primer is more likely due to the synergistic effect between the zinc epoxy phosphate in the semi-finished product B, the semi-finished product C and the PVB resin in the semi-finished product D and the other substances in the semi-finished product B and the semi-finished product C and the semi-finished product D;
As can be seen from examples 1 and 4 to 7, when the n-butanol or the semi-finished product C is added not twice but once, the water resistance of the primer is reduced to a small extent, and it is presumed that the reason is that the n-butanol or the semi-finished product C cannot be fully reacted or mixed with other raw materials by one addition, and thus the effect of the n-butanol or the semi-finished product C cannot be fully exerted;
As can be seen from example 1 and comparative examples 8 to 10, the water resistance of the primer was significantly reduced when Desettle p, afcon a2020, afcona 4010 were absent from the raw materials of the primer, and it can be seen that Desettle p, afcon a2020, afcona 4010 described above are indispensable components in the primer for one-component galvanized sheet;
It can be seen from example 1 and comparative examples 11 to 13 that, when Desettle p, afcon a 2020, afcona4010 were replaced with canfair p, BYK052, and DISPERBYK-163, the water resistance of the one-component primer for galvanized sheet was lowered to various degrees, and Desettle p, afcon a 2020, afcona4010 were not replaced in the raw materials of the one-component primer for galvanized sheet.

Table 7:
Analysis of results:
As can be seen from examples 1 and comparative examples 1 to 3, although the semi-finished product B contains a large amount of zinc epoxy phosphate, the semi-finished product C and the semi-finished product D contain a large amount of PVB resin, when the zinc epoxy phosphate is used to replace the semi-finished product B and the semi-finished product D is used to replace the semi-finished product C and the semi-finished product D, the salt spray resistance of the primer is reduced to different degrees, and in combination with fig. 7, it can be seen that the trace of salt spray corrosion in comparative examples 1 to 3 is significantly more serious than that in example 1, therefore, it is considered that the factor for improving the salt spray resistance of the primer is not only because of the zinc epoxy phosphate in the semi-finished product B, the PVB resin in the semi-finished product C and the semi-finished product D, but also comprises other substances in the semi-finished product B, the semi-finished product C and the semi-finished product D, and the improvement of the salt spray resistance of the primer is more likely due to the synergistic effect between the zinc epoxy phosphate in the semi-finished product C and the PVB resin in the semi-finished product D and the other substances in the semi-finished product B and the semi-finished product D;
as can be seen from examples 1 and 4-comparative example 7, when n-butanol or semi-finished product C is not added twice but added once, the salt spray resistance of the primer is reduced to a small extent, and it is presumed that the reason for this is that the one-time addition may be that the n-butanol or semi-finished product C cannot sufficiently react or mix with other raw materials, and thus the effect of the n-butanol or semi-finished product C cannot be sufficiently exerted;
As can be seen from example 1 and comparative examples 8 to 10, when Desettle p, afcon a2020, afcona4010 were absent from the raw materials of the primer, the salt spray resistance of the primer was significantly reduced, and it can be seen that Desettle p, afcon a2020, afcona4010 described above are indispensable components in the primer for one-component galvanized sheet;
It can be seen from example 1 and comparative examples 11 to 13 that when Desettle p, afcon a 2020, afcona4010 were replaced with canfair a, BYK052, and DISPERBYK-163, the salt spray resistance of the one-component primer for galvanized sheet was lowered to various degrees, and Desettle p, afcon a 2020, afcona4010 were not replaced in the raw materials of the one-component primer for galvanized sheet.
