The following are the results of testing the products prepared in examples 1-3.
Test example 1 calculation of Corrosion Rate in Uniform immersion experiment
After uniform immersion etching for 480 hours in 3.5wt% NaCl solution, the etching rates of the five groups of samples were obtained by calculation.
TABLE 1 Corrosion Rate for each set of samples
It can be seen that the five groups of samples all show better corrosion resistance, the corrosion rate is less than 0.1mm/a, and the addition of the phytic polyaniline can be seen to significantly improve the corrosion resistance, wherein the corrosion rate of the tinplate sample doped with 5wt% of the phytic polyaniline adhesive tape is the slowest and is 0.014mm/a.
Test example 2. Intermediate immersion test
The immersion test refers to the test piece with metal coating is alternately immersed in a liquid corrosive medium and exposed to air. The cross dip test is a simulation test and also an accelerated test.
Samples 1-5 were prepared as in test example 1.
The experiments used 3.5wt% NaCl solutions with a period of 8h, a dry-to-wet time ratio of 1. The resulting etch pictures after 30 cycles are shown in figure 2.
The corrosion condition of the sample 1 (figure 2 a) is severe, the scratch is corroded deeply, the scratch of the sample 2 (figure 2 b) generates corrosion traces, the scratch of the sample 3 (figure 2 c) slightly corrodes, the corrosion of the sample 4 (figure 2 d) aggravates again, it can be seen that the corrosion resistance changes to a certain extent along with the change of the specific gravity of the polyaniline, and the 5wt% phytic acid doped polyaniline adhesive tape has better corrosion resistance. The commercially available corrosion protection coating (fig. 2 e) not only produces corrosion at the scratches but also spreads with it.
Test example 3.180 ° peel strength test
180 peel strength is an important indicator of the measurement and evaluation of the adhesive properties of an adhesive product. Generally, two adhered materials are prepared into an adhered sample by using an adhesive, then the adhered sample is peeled from an opening of the adhesion at a specified speed, and the two adhered materials are gradually separated along the length direction of the adhered surface. The peel force applied through the flexible adherend is substantially parallel to the adhesive face. The adhesive bonding test piece consisting of two bonded materials (one is a flexible material and the other is a rigid material) has 180-degree stripping resistance under specified conditions. ( When the 180 DEG peel force is greater than or equal to 0.2N/mm, the glue sample is considered to have acceptable initial tack; when the measured 180 ° peel force is greater than or equal to 0.3N/mm, the glue sample is considered to have good initial tack; when the 180 DEG peel force measured is greater than or equal to 0.45N/mm, the gum sample is considered to have excellent initial tack. )
Adhering the prepared anti-corrosion adhesive tape to the surface of a steel plate with a smooth and finished surface, irradiating for 1-3min under a UV-LED device with the wavelength of 365nm to fully cure the adhesive, and then carrying out peel strength test, wherein the average value of five groups of adhesive tape data is as follows: 0.324N/mm. The test result shows that the invention has good initial viscosity and can meet the practical application.
